Introduction

The Longitudinal Administrative Databank (LAD) is a subset of the T1 Family File (T1FF). The T1FF is a yearly cross-sectional file of all taxfilers and their families. Census families are created from information provided annually to the Canada Revenue Agency in personal income tax returns. Both legal and common law spouses are attached by the spousal Social Insurance Number (SIN) listed on the tax form, or by matching based on name, address, age, sex, and marital status. Children are identified through a similar algorithm and supplementary files. Prior to 1993, non-filing children were identified from information on their parents' tax form. Information from the Family Allowance Program was used to assist in the identification of children. Since 1993, information from the Child Tax Benefit Program has been used for this purpose.

The LAD is a random, 20% sample of the T1FF. Selection for LAD is based on an individual's SIN. There is no age restriction, but people without a SIN can only be included in the family component. Once a person is selected for the LAD, the individual remains in the sample and is picked up each year from the T1FF if he or she appears on the T1 that year. Individuals selected for the LAD are linked across years by a unique LAD identification number (LIN__I) generated from the SIN, to create a longitudinal profile of each individual. The LAD is augmented up each year with a sample of new taxfilers so that it consists of approximately 20% of taxfilers for every year. The 20% sample has increased from 3,227,485 people in 1982 to 5,332,700 in 2012 (an increase of 65%). This increase reflects increases in the Canadian population and increases in the incidence of tax filing as a result of the introduction of the Federal sales tax credit in 1986 and the Goods and Services Tax credit in 1989.

The LAD is organized into four levels of aggregation, namely the individual, spouse/parent, family, and child(ren) levels. The databank contains information on demographics, income, and other taxation data at the different levels of aggregation from 1982-2012, with new years of data being added as the information becomes available. Changes in tax legislation and in the design of the T1 form itself have resulted in some variables not being available for all years as well as some minor definitional changes from one year to the next.

The LAD is currently linked with the Longitudinal Immigration Database (IMDB) containing immigration records from 1980 to 2011. This linkage has been approved by the Statistics Canada Policy Committee.

The LAD has been designed to serve as a research tool from which custom tabulations can be prepared. This dictionary, in turn, has been created to assist researchers in identifying the type of information that is available from the LAD. It identifies and defines the LAD variables including historical changes.

Confidentiality

Statistics Canada protects the confidentiality of individuals' tax data. Only aggregated information that conforms to the confidentiality provision of the Statistics Act is released. The LAD resides within Statistics Canada and all retrievals are done on site. Only a small staff within the Income Statistics Division (ISD) can access such data directly. This means that users must specify their data requirements to these persons who then carry out the retrieval. More information on the confidentiality procedures can be obtained from Client Services.

Geography

Data from the LAD are available for various levels of geography including Canada, provinces/territories, and regions (such as Census Division (CD), Census Metropolitan Area /Census Agglomeration (CMA/CA), Census sub-division (CSD) and Census Tracts (CT), etc.). Many other levels of geography are not included on the main LAD database, for example Economic Region (ER) and Federal Electoral District (FED); however these are available in the LAD using the Postal Code Conversion File.

Dictionary format and contents

Outlined below is a brief description of the next nine sections of the LAD Dictionary.

The LAD register (Section 5) is a file that is used in conjunction with the yearly LAD files. The Register outlines the years that an individual is on the LAD and provides information on the taxfiler's sex, year of birth, and year of death. This section provides a brief description of this file and describes how it can be used to enhance LAD data analysis.

The Programming tips section (Section 6) provides information on writing programs for LAD retrievals. This information will assist those individuals who want to better access data from LAD files using the effective programming structure.

The Design of LAD variable acronyms (Section 7) is a description of the variable acronym structure. It provides insight into how to interpret the variable acronyms and information on the aggregation levels.

The LAD variable definitions (Section 8), alphabetically lists each variable by name. In addition, the following information is provided for each variable:

The years the variable is available on the LAD. The term ‘present' denotes the most recent year of LAD data available.
The definition of the variable.
The source of the variable such as the line number on the tax form or through LAD processing.
Where relevant, the availability and historical continuity of the variable in relation to Canada Revenue Agency's definition of total income (TIRC_) and to ISD's definition of Total Income (XTIRC). This information is provided only for those variables that are a component of either definition of total income. For additional information on the income variables see Section 10, Definition of total income variables.
The acronym used to identify each variable and the aggregation levels available.

The Variable counts and amounts for individuals, outlines, for many variables, at the individual aggregate level, the count of individuals and the dollar amounts reported for the two most recent years of LAD data. Persons included in these counts and amounts are those who have been selected into the LAD sample.

The Correspondence with the IMDB variables presents the variables from the Longitudinal Immigration Database (IMDB) that are linked with the LAD.

The Definition of total income variables (Section 10) identifies and defines total income variables and highlights historical changes. Also provided are tables that outline and compare the variables that comprise market income and the Canada Revenue Agency's (CRA) and Income Statistics Division's (ISD) definitions of total income.

The tables outlined in this section are the following:

Table 1 Components of XTIRC for the most recent year of LAD data.

LAD register

The LAD register is a companion data file to the yearly LAD files. It contains a selected number of variables for all individuals who are present at any time in the LAD. These variables have characteristics that should remain constant over time and thus may not be identified in a particular yearly file. A new LAD register is created every year with the addition of a new LAD yearly file from taxfiler information provided from living or deceased taxfilers and imputed individuals. Thus, the current register contains the most up-to-date information on individuals present in the LAD. On rare occasions, new information on individuals may differ from that on the existing file. In these instances, current information supersedes information in the existing LAD register.

The LAD register is a quick reference tool that can provide basic data without accessing the yearly files. For example, information such as the number of individuals in the LAD by age and sex in a given year can be tabulated directly from the register. Further, the LAD register can be employed in conjunction with the yearly files. In particular, it is recommended that the age of an individual be calculated from the register's information on the year of birth rather than relying on the age information in the yearly files in order to ensure that it is consistent across years.

Following is a list of the variables that can be found on the register:

LIN__I: This is a numeric variable uniquely identifying each individual in LAD

SXCO_I: This is a character variable identifying the sex of the individual.
‘F': females ‘M': males
‘ ': when blank, the sex of the individual has not been identified

YOB__I: This is a four digit numeric field identifying the year of birth of the individual (e.g. 1947). The age of the individual in any given year can be calculated by subtracting the year of birth from that given year (e.g. in 2000, an individual born in 1965 would be 2000-1965 = 35 at the end of the 2000 calendar year).

YOD__I: This is a four digit numeric field identifying the year of death of the individual. For individuals who have not passed away, this field is missing.

FLAG_I (plus the relevant LAD year, for example FLAG_I1982, etc). These are character variables that identify the years in which an individual is present in the LAD files. They take the following values:
‘1': the individual has filed in that year
‘2': information for the individual has been imputed for that year
‘ ': (blank): the individual is not present in that year.

TTNFLI: Flag to indicate whether or not an individual has a temporary SIN, where:
‘Y' (Yes) = Temporary SIN;
‘N' (No) = No temporary SIN.

Temporary SINs are issued to temporary workers, non-residents, students with student visas, etc. In these cases, a SIN may change from one year to the next if, for instance, the individual becomes a permanent resident or a Canadian citizen. In the LAD files, LIN__I generated from the original SIN is maintained in order to ensure that information for an individual can be linked across years.

IMMFLI: Flag to indicate whether or not an individual is a Canadian immigrant, who landed between 1980 and the present, where:
‘Y' (Yes) = Immigrant;
‘N' (No) = Not an immigrant.

LNDYR I: This is a four digit numeric field identifying the landing year in which the immigrant landed (e.g. 1990). For individuals who are not an immigrant, this field is missing.

WGT__I^{Note : 1} : This is an individual noise weighting variable used with all procedures invoked in the SAS programs on the LAD 10% sample. It is a noise variable used to protect confidentiality. This variable is also found in the yearly files.

WGT2_I: As the previous variable this is an individual noise variable used to protect confidentiality. This weighting variable is used with all procedures invoked by the SAS programs with the LAD 20% sample. This variable is found in the yearly files as well.

Programming tips

This section provides programming information for individuals who want to have a better understanding of the programming structure used to access data from the LAD files. Please note that individuals may undertake their own programming, however, only a small staff within Statistics Canada can carry out these retrievals. Access to the LAD files is restricted to protect the confidentiality of an individual's tax data and any data that are made available will be screened through a set of rules designed to prevent disclosure.

There are two types of LAD files— the yearly LAD data files and the LAD register (for more details on the LAD register, refer to section 5, LAD register). LAD variables are identified with a variable name that consists of three parts: 1) the acronym name, 2) the aggregate level, and 3) the year (the four-digit year extension exists in most, but not all cases). Observations in the LAD files are sorted by a variable, named lin__i (note that there is no year extension for this variable), which enables users to maintain a link across years.

Data access is undertaken with SAS programming language. The next page contains a sample SAS program designed to access LAD data. The library assignments on the first three lines are the locations for the input files (first two lines) and the output files (the third line). The input files are in SAS format and can therefore be accessed with a SET or MERGE statement. This 20 % sample based program is aimed at retrieving the number of Social Assistance (SA) recipients in Ontario that did not have any earnings appearing on their T4 slips,according to sex and year (in this case, 2000 to 2002). It is generally recommended that programs use the variables available in the register rather than the yearly files because the register information contains the most recent data. For example, the following program uses sxco_i, a variable found in the register, rather than sxco_i&yr, the variable found in the yearly LAD files. The flag_i&yr variables in the register are useful to identify individuals who have filed in a given year. In this program, only individuals who have filed every year from 2000 to 2002 are selected. At the end of the program, four tables are created from the output data file. Note that for confidentiality purposes, the weight variables wgt__i (with the LAD 10% sample) or wgt2_i (with the LAD 20% sample) must be used whenever a SAS procedure such as FREQ or LOGISTIC is invoked.

When programming in SAS, it is important to keep in mind the distinction between missing values and zeros in numeric fields. With SAS, most mathematical operations undertaken with missing values will return missing values. In LAD, in years that an individual is present, numeric variables not relevant to that individual have a value of zero. For example, if a non-family person has filed in 2000, then the value for RRSPSI2000 (contributions to a spouse's RRSP) should be zero. If that individual has not filed in 2000, then the value will be missing. Thus, as a safety precaution, it is suggested that all numeric variables to be used in mathematical expressions be initialized to zero if missing, before using them.

Sample LAD program

* Sample SAS program using the LAD;

libname source1 '/LADdata/data1'; * first 10% sample ;
libname source2 '/LADdata/data2'; * second 10% sample ;
libname Out '/LADuser/xxxx/data'; * user's directory ;

* This sample program's objective is to use the 20% LAD to retrieve the number of Social Assistance (SA) recipients in Ontario that did not have any earnings appearing on their T4 slips, according to sex and year (in this case, 2000 to 2002). Data for provinces and earnings are from the yearly LAD files whereas the sex variable is from the 2002LAD register (the most recent). ;

* The first step is to create a datafile containing all the information that we need to produce our tables. This datafile will be called SAOnt and will be saved in the 'out' directory. The Longitudinal Identifier Number (LIN__I) is used to merge the annual LAD datasets. ;

Design of LAD variable acronyms

Most LAD variables have a ten-character acronym. Each acronym consists of three parts, namely the variable name (five characters), the aggregate level (one character), and the calendar year (four characters), e.g. XTIRCI2000.

The variable name is the principal component of the acronym. The characters identify the type of information provided by the variable (see section 8 "LAD Variable Definitions").

The one-character aggregate level character provides information on individuals of the census family according to the designated level of aggregation. There are four possibilities, namely ‘I', ‘P', ‘F', and ‘K' representing individual, parents, family and children (kids) respectively. The family types outlined in these aggregate levels refer to the status of the family at the end of the tax year. Following are details about each of these aggregate levels:

I (Individual):
A variable with this aggregate level provides information only for the individual (to be selected into the sample, an individual must have a SIN). In most cases this information is taken from the individual's own tax form^{Note : 2}, though some individuals who have not filed are imputed from a spouse's tax form or from information from an earlier year, and therefore have imputed information (since 1993 imputed children can be selected into the sample).

P (Parents/spouse):
This aggregate level indicates that the variable contains data for the parent(s) in the census family for couple families or for single-parent families. For couple families, Parents/spouse represents the partner's individual characteristics. The income is the sum of the income of the two parents / spouses. The partner's income in particular year is the difference between this summed income and the individual income eg. XTIRCP2000 – XTIRCI2000. In the case of lone-parent families or persons not in census families, Parents/spouse is the parent's or person not in census families' individual information.

Because deceased people are attached to families, there are some cases in which variables at the ‘P' aggregate level contain information for more than two individuals. If an individual who is a person not in a census family as of December 31st of the year had a spouse who died during the year, the parent aggregate level may contain information for both the individual and his or her spouse. This can occur if an individual's spouse has recently passed away and the individual has since remarried. In such cases, the ‘P' variables can contain information for three people, the individual, the individual's living spouse, and the individual's deceased spouse. There are a few variables with a ‘P' aggregate level that provide information on only one person in the census family regardless of the family composition. These variables include age, gross business / commission / farming / fishing / professional income, immigrant/emigrant code, English/French language, landing year and year of death.

F (Family):
This aggregate level indicates that the information in the variable is an aggregate of all members in the individual's census family, including the individual himself/herself. Once again, note that deceased individuals are attached to families; therefore this variable can contain information aggregated over more individuals than just the census family. The exceptions are LIMATIyyyy and LIMXTIyyyy, which are the low income status variables using ISD's after-tax income and total income definitions, respectively. These two variables are dichotomous variables (i.e. 0 or 1). Additional exceptions are gross business income (BGRS_Fyyyy), gross commission income (CMGRSFyyyy), gross farming income (FMGRSFyyyy), gross fishing income (FSGRSFyyyy), and gross professional income (PFGRSFyyyy), which contain the largest gross self-employment income amongst all the people in the census family.

K (Kids):
This aggregate level indicates that the information in this variable pertain to children in the census family. Note that these variables are on a different file. There are only two variables available for all children in a census family. They are age (AGE__Kyyyy) and the family identification number (FIN__Iyyyy). The remaining ‘K' variables have information only for tax-filing children, and are left blank or replaced by zero for non-filing children.

The four-characters for the calendar year, identifies the year to which the variable is associated. The LAD data are stored in separate files for each calendar year; therefore all variables in a particular year file will have the same four-character calendar year reference. The only exception in the yearly files is the variable LIN__I, the LAD individual identification number, which is available for each observation present in each year file, but does not have a calendar year as part of the acronym (note that there is also a variable for spousal LIN (LIN__Pyyyy^{Note : 3}) which does have the year extension as part of the acronym name). In the register file, the exceptions to the four character year are LIN__I, SXCO_I, YOB__I, YOD__I, LNDYRI, TTNFLI and IMMFLI, which are the individual's LIN, sex, year of birth, year of death, landing year, temporary SIN flag, and immigrant flag, respectively.

Business income, gross

(1982 to present)

Definition: Gross business income is the entire income of the taxfiler's unincorporated business (e.g. dentist, accountant, physician, etc.), before costs and expenses are deducted. If the enterprise is a partnership, each partner reports the income of the whole operation.

Until 1994, reporting of self-employment income was on a fiscal year basis and the fiscal year end was the end of the taxation year for reporting this income. Beginning in 1995, most individuals are required to report self-employment income on a calendar year basis. However, eligible individuals may be able to use an alternative method of reporting whereby the fiscal period does not end on December 31. Due to this rule change, individuals reporting self-employment income in 1995 may have reported more than one fiscal year's income (i.e. more than 12 months).

Note: When this variable is reported for more than one person in a family, the family and parents aggregate levels contain only the amount from one of these persons, precisely the highest value from all. It has been assumed that when more than one person in the family report this self-employment income, these family persons are supposed to be all working for the same business.

Census Division (CD)

(2009 to present)

Definition: Census division (CD) is the general term for provincially legislated areas (such as county, "municipalité régionale de comté" and regional district) or their equivalents. Census divisions are intermediate geographic areas between the province/territory level and the municipality (census subdivision). A census division is a group of neighbouring municipalities joined together for the purposes of regional planning and managing common services (such as police or ambulance services). These groupings are established under laws in effect in certain provinces of Canada.

For example, a census division might correspond to a county, les municipalités régionales de comté or a regional district. In other provinces and the territories where laws do not provide for such areas, Statistics Canada defines equivalent areas for statistical reporting purposes in cooperation with these provinces and territories. Each CD is identified by a unique four-digit code including the code of the province (first two-digits) and the CD code (third and fourth digits). For example:

To be included in the CMA or CA, other adjacent municipalities must have a high degree of integration with the central urban area, as measured by commuting flows derived from census place of work data.

If the population of the urban core of a CA declines below 10,000, the CA is retired. However, once an area becomes a CMA, it is retained as a CMA even if its total population declines below 100,000 or the population of its urban core falls below 50,000. The urban areas in the CMA or CA that are not contiguous to the urban core are called the urban fringe. Rural areas in the CMA or CA are called the rural fringe.

When a CA has an urban core of at least 50,000, it is subdivided into census tracts. Census tracts are maintained for the CA even if the population of the urban core subsequently falls below 50,000. All CMAs are subdivided into census tracts. For Census metropolitan area 2006 there are 33 census metropolitan areas in Canada. Each CMA or Census Agglomeration (CA) in Canada is identified individually by the two-digit code of the province followed by a unique three-digit code for the CMA/CA. For example:

Census Metropolitan Area - unique

(1995 to present)

Definition: This variable incorporates geographic codes from other levels of geography (for example, province) to obtain a unique census metropolitan area (CMA) code. The variable utilizes census geography information applicable to the year in which the variable is created. Users should be aware that census geography information changes over time, being updated with each new census. In addition, postal code boundaries do not correspond perfectly with census geography boundaries. For additional information please consult the most recent CMA variable using census geographies (for example: CMA06).

Census tract (CT)

(2009 to present)

Definition: Census tracts (CTs) are small geographic units representing urban or rural neighbourhood-like communities in CMAs or CAs (with an urban core population of 50,000 or more at the previous census). Each census tract is assigned a seven-character numeric 'name' (including leading zeros, the decimal point and trailing zeros). To uniquely identify each census tract in its corresponding census metropolitan area or tracted census agglomeration, the three-digit CMA/CA code must be added to and precede the CT 'name'. For example:

Children, total number by specific year of age

(2010 to present)

Definition: These variables provide the total number of children that each tax filer may have, by the specific age for those children, ages 0 through to 18 years. A single additional variable provides information for those filers with children aged 19 years and older. A value of 0 (zero) for any variable indicates that the filer does not have a child of that age. A value of 1 or greater indicates that the filer has that specific number of children of the particular age variable. For example, if a filer has three children, one aged 6 months and two other children aged 3 years, then for that filer the variable TNK00 would have a value of 1, and the variable TNK03 would have a value of 2. For further information please also see variable KID_ "Children, total number in family".

Child Tax benefit

(1993 to present)

Definition: The Child Tax Benefit (or Canada Child Tax Benefit, CCTB) is a program that replaces (beginning from 1993) the previous federal Family Allowance program, the non-refundable child deduction and the refundable Child Tax Credit. It is an income supplement for individuals who have at least one qualified dependent child. Factors involved in determining the Child Tax Benefit (CTBI) include: the number of dependent children, their ages and family income. Provided all eligibility requirements are met, the benefits will continue until the month following the child's 18th birthday.

Derived from: i (CTB) file

Child Tax credit

(1982 to 1992)

Definition: The child tax credit provided assistance in meeting the costs of raising children for low to middle-income families. It was available to taxfilers with eligible children. Between 1982 and 1987, an eligible child had to be less than 18 years old the entire tax year in order to be qualified. From 1988 to 1992, an eligible child was any child who was under 18 and for whom the taxfiler could claim Family Allowance (FA___). If the child became 18 during the tax year, the child was eligible for all months including the month of his or her 18th birthday as long as he or she was still eligible for Family Allowance (FA___).

Since 1986, a child tax credit prepayment was made to low income families. To determine the amount of child tax credit still owing the taxfiler, the prepayment amount was subtracted from the total child tax credit amount. If the prepayment amount was larger than the full credit, the taxfiler had to repay the difference.

Since 1988, a supplement for children under seven years old was also available to taxfilers. This supplement was reduced by 25% of the child care expenses claimed for these children. The remaining amount was added to the child tax credit.

Children, number of children under age 18

(2007 to present)

Definition: The number of children under age 18 at the end of the taxation year for whom the children amount deduction was claimed. For 2007, and later years, a personal amount may be claimed for each child under age 18 at the end of the taxation year. The amount is independent of any income the child may have; that is, it is not reduced by any amount if the child has income of his or her own.

Children, ages of the seven youngest

(1982 to present)

Definition: The ages of the seven youngest children are available on the LAD file. Another file, the KIDS file, contains the ages of all the children in the families on the LAD. Taxfiling children's ages are calculated by subtracting the child's year of birth from the tax year of the data. Non-taxfiling children's ages were imputed in 1982 and 1983. From 1984 to date, most of the ages of children have not been imputed. The major sources of information on ages for children are as follows: from 1984 to 1992, Family Allowance and from 1993 to date, the Child Tax Benefit file.

Please note that children may be any age, i.e. a 40 year-old child may be living with a 60 year-old parent. This variable is considered as a cross-sectional variable rather than a longitudinal variable because there are inconsistencies from year to year in children's ages. The order in which the children are outlined on the file is from the youngest (most recent child) to the seventh youngest.

Children, total number in family

(1982 to present)

Definition: The total number of children in a family is identified in this field. A child is defined as someone who is single and living with one or both parents. Please note that children may be any age, i.e. a 40-year-old child may be living with a 60-year-old parent.

The number of children might have changed in a family over the 2005-2008 period due to improvements to the T1FF process of identifying children and the introduction of the Children Fitness tax credit (CFA) and Children Amount Deduction (CHAD) in 2007 and the Universal Child Care Benefit program in 2006 allowing for the identification of more children. These changes have resulted in improved coverage of children in the T1FF. The impact of these changes is most notable in the count of imputed children from lone-parent families although it is not possible to distinguish the precise impact of the improvements separately from normal year-to-year change.

Children amount deduction

(2007 to present)

Definition: A taxfiler can claim a federal non-refundable tax credit for each child under age 18 at the end of the taxation year. The amount is independent of any income the child may have; that is, it is not reduced by any amount if the child has income of his or her own:

The full amount can be claimed in the year of the child's birth, death, or adoption.
If the child resides with both parents throughout the year, either the filer or spouse or common-law partner can claim this amount.
If the child does not reside with both parents throughout the year, the parent or the spouse or common-law partner who claims the amount for an eligible dependant for that child, can claim this amount.

CPP or QPP deduction or tax credit on self-employment earnings

(2002 to present)

Definition: CPPSE represents 50% of the Self employment CPP/QPP calculated contributions. In the case of self-employment, the taxfiler contributes both halves of CPP and QPP. This amount gets reported on Line 222 and also in Schedule 1, line 310, representing the employer and employee components. You can claim contributions you have to make on self-employment and limited or non-activity partnership income, or those you choose to make on certain employment income (making additional CPP contributions at line 308), or those you choose to make on your provincial income tax return for Quebec on certain employment income (see PQ guide). (See also CLCPP and CLQPP).

Calculated Canada Pension Plan Payable Self-Employment. A taxfiler is entitled to a maximum credit equal to 17% of the CPP/QPP contributions paid in the year. For partnerships, a taxfiler must include only his/her part or net profit or loss. The calculated Canada Pension Plan payable on self-employment is a component in the calculation of total non-refundable tax credits. If the taxfiler's business losses are more than his/her profits, he/she cannot use the loss to reduce CPP contributions paid on employment earnings. If eligible, the taxfiler may make additional contributions to the pension plan up to the maximum annual contribution. This would increase the amount of his/her pension in the future. If the taxfiler contributed more than the maximum amount during the tax year, Canada Revenue Agency would refund the excess amount. Self-employed persons are allowed a maximum contribution based on their maximum contributory earnings(see also variables CLQPP and CPPSE).

CPP/QPP total contributions payable from self-employment

(1982 to present)

Definition: This variable measures the total amount of CPP/QPP contributions payable from self-employment. Up until the end of 2001, this variable (CLCPP) measured both CPP and QPP contributions from self-employment. However, for the period from 2002 onward two important changes occurred. The first major change was the introduction of a new variable CPPSE. Whereas the variable CLCPP measured all contributions payable to CPP/QPP, the new variable CPPSE measures 50% of the total contributions payable on all CPP/QPP contributions (see the definition of CPPSE). The second major change was that from 2002 onward CLCPP measures only the contributions for CPP. Contributions payable to QPP from self-employment, from 2002 onward, are now available in the variable CLQPP.

PRIOR TO 2002
(1982 to 2000)
The Canada Pension Plan (CPP) and the Quebec Pension Plan (QPP) are compulsory contributory social insurance plans that protect workers and their families against loss of income due to retirement, disability or death. Most employed and self-employed individuals between the ages of 18 and 70 years are required to make contributions based on their earnings. When the taxfiler is employed, the employer contributes half the CPP and QPP by matching the employee's contributions. When self-employed, the individual can contribute both halves to either the CPP or QPP. However, if the taxfiler has both wages and self-employment earnings, the amount of CPP contributions made through self-employment earnings will depend on the amount already contributed as an employee to the CPP or QPP.

(2000 to 2002)
When the tax filer is self-employed, the individual can contribute both halves of contributions either for the CPP or QPP. However, if the taxfiler has both wages and self-employment earnings, the amount of CPP contributions made through self-employment earnings will depend on the amount already contributed as an employee to the CPP or QPP. The tax filer can claim, on line 310 of Schedule 1, half of the total of your CPP or QPP contributions, if any, from Schedule 8. The tax filer can also claim on line 222, an amount for the other half.

2002 AND AFTER
Since 2002, measurement of the total amount payable from self-employment contributed to CPP/QPP by taxfilers has changed. First, the variable CPPSE was introduced to measure the total deductions and tax credits available from self-employment income (since taxfilers can contribute both halves, the variable CPPSE measures half of the total, effectively either the employee or employer half).

The second change to the variable CLCPP is that for those taxfilers residing in Quebec with Quebec Pension Plan (QPP) contributions payable on self employment, the total amount of these contributions are no longer included in the variable CLSPP but are instead included in a new variable, CLQPP. CPP contributions payable on self employment are still part of the variable CLCPP for taxfilers who do not reside in Quebec.

A user wishing to obtain the total of CPP/QPP contributions payable from self-employment in the period after 2002 must combine the results from CLCPP and CLQPP. Alternatively, users could also double the amount of the variable CPPSE.

CPP/QPP contributions through employment T4

(2002 to present)

For a taxfiler who receives an income for a paid employment, the employer contributes half of the CPP/QPP and the taxfiler contributes the other half.

Definition: This is the amount that an individual contributes to their Canada Pension Plan (CPP) and the Quebec Pension Plan (QPP). The CPP and QPP are compulsory contributions to social insurance plans that protect workers and their families against loss of income due to retirement, disability or death. Most paid employees and self-employed individuals between the ages of 18 and 70 years are required to make contributions based on their earnings. A taxfiler who is self-employed pays the entire amount of the CPP/QPP contribution. For a taxfiler who receives an income for a paid employment, the employer contributes half of the CPP/QPP and the taxfiler contributes the other half. If the taxfiler has both wages and self-employment earnings, the amount of CPP contributions made through self-employment earnings will depend on the amount already contributed as an employee to the CPP or QPP.

Credit for interest paid on a student loan

(1999 to present)

Definition: The amount of the credit for interest paid on a student loan beginning in 1998 as calculated by CRA. There is a five-year optional carried forward that is available, to the extent that the taxfiler cannot (because the tax amount is insufficient for the use of the credit) or chooses not to claim interest paid in the current year. The taxfiler can claim the carried forward amount in any of the five subsequent years. The taxfiler cannot carry forward amounts paid in 1997 or earlier. This rule is valid, beginning in 1998 only.

To be eligible for the credit, interest must have been paid and not merely due or payable. It is only the student to whom the loan was made that can claim the credit. However, the interest does not necessarily need to have been paid by the student; the student can claim the credit if the interest was paid by the student or anyone related to her/him. Also to be eligible for the credit, the interest must be on a loan made under the Canada Student Loans Act.

The amount of interest paid is entered at line 319 and converted to a 17% credit at line 338.

Disability amount for a dependent other than spouse

(1986 to present)

Definition: The taxfiler may claim the unused portion of the disability amount for a dependent who resides in Canada, if he or she claimed either an "Amount for dependent children" (Line 231, 1986 to 1987; Line 304, 1988 to present), or the "Equivalent amount for spouse" (Line 230, 1986 to 1987; Line 305, 1988 to present), for that dependent. Starting with the 2000 tax year, the claim also applies if the dependant was the spouse's sister, brother, aunt, niece or nephew.

Dividends

(1982 to present)

Definition: Dividends are, for tax purposes, defined as a share of the profits of a Canadian corporation, which are distributed to its shareholders. Dividends should be reported as income on the T1 Tax Form in the year they are received.

The Canada Revenue Agency adjusts dividends upward to create taxable dividends (DIVTX). The Dividends variable on LAD (XDIV_) represents the actual amount of dividends received by the taxfiler before that amount is "grossed-up" by the Canada Revenue Agency. Dividends are calculated using the following equation:

2006 to present:
- XDIV_ = (DIVTO * gross-down factor1) + (DIVTE * gross-down factor2)
- Where:
  - DIVTX = Total taxable amount of dividends (eligible and other than eligible dividends) from
  - taxable Canadian corporations, line 120.
  - DIVTO = Taxable amount of dividends other than eligible dividends, line 180.
  - DIVTE = Taxable amount of eligible dividends, DIVTE = ((DIVTX – DIVTO).
  - Gross-Down Factors = reciprocals of the Canada Revenue Agency's Gross-Up Factors.
    - gross-down factor1 (gross-down factor for other than eligible dividends) = 1/1.25 (2006 to 2011).
    - gross-down factor2 (gross-down factor for eligible dividends) =
    - 1/1.45 (2006 to 2008)
    - 1/1.44 (2009 to 2010)
    - 1/1.41 (2011)
    - 1/1.38 (2012)
- 1982 to 2005:
  - XDIV_ = DIVTX * gross-down factor
  - Where:
    - DIVTX = Taxable amount of dividends from taxable Canadian corporations, line 120 (1984 to 2005), Line 14 (1982 to 1983).
    - Gross-Down Factors = reciprocals of the Canada Revenue Agency's Gross-Up Factors
      - 1988 to 2005 = 4/5
      - 1987 = 3/4
      - 1982 to 1986 = 2/3

Derived from: T1FF processing.

TIRC_: DIVTX Included from 1982 to present, as the taxable amount (i.e.: grossed-up)

Donations and gifts tax credit, federal non-refundable

(1995 to present)

Definition: This variable is the total federal non-refundable tax credit for donations and gifts.

Derived from: Line 349 and Schedule 9

LAD: CDGFT I, F, P

Donations

(1983 to present)

Definition: Donations is the sum of the taxfiler's charitable donations (1983 to present), government gifts (1983 to present), cultural donations (1984 to present) and ecological gifts (1995 to present).

Charitable donations consist of any donations to registered charities and athletic associations. For tax purposes, charitable organizations must be devoted to a valid activity and no part of their income can be made available for personal benefit of any proprietor, member or shareholder. In addition, the organization must have registered with the Department of National Revenue.

These organizations include:

Canadian registered charities;
Registered Canadian amateur athletic associations;
Prescribed universities outside Canada;
Canadian non-profit organizations that only provide low-cost housing for seniors;
Registered national arts service organizations;
The United Nations (or its Specialized Agencies);
Charities outside Canada to which the Government of Canada has made a donation in 1996 or 1997.

Government gifts: consist of any gift to Canada, a province, or a cultural organization.

Cultural donations: The Cultural Property Export and Import Act contains provisions to encourage the retention of national treasures (Canadian cultural property) within Canada. Under these provisions, taxpayers are encouraged to dispose of such property to designated institutions or public authorities in Canada. Gifts of cultural property to a designated public authority or institution in Canada and certified by the Canadian Cultural Property Export Review Board will entitle the taxfiler a tax credit as a donation. The amount eligible for credit is not limited to a percentage of the taxfiler's net income for the year. Any portion not claimed in a year may be carried forward to the next five years.

Ecological gifts: A taxfiler can claim the amount for a gift of land that was certified by the Minister to be important to the preservation of Canada's environmental Heritage. Donations made after February 27, 1995, may be claimed. These donations must be made to a Canadian Municipality or a registered charity designated by the Ministry of Environment.

The following summarizes the method of reporting donations:

From 1983 to 1987:
Donations were a deduction from net income and the taxfiler could claim the entire amount of charitable donations that were the lower of:

The total donations made in the tax year plus any donations not previously claimed. In 1983, an individual could claim 1981 and 1982 donations if they had not been previously claimed. In 1984, donations made after 1980 could be claimed if they had not been previously. Beginning in 1985, any donations made in the previous five years, which included the current tax year, could be claimed, or
20% of his or her net income in the current tax year.

From 1983 to 1995:
A taxfiler receiving income from U.S.A. sources may claim donations made to U.S.A. charitable organizations. This claim was restricted to 20% of U.S.A. income.

From 1983 to present:
Donations not previously claimed may be carried forward for up to five years from the year of the donation unless the donations were made in 1982 or 1983 and the optional $100 donations/medical expenses deduction was claimed. This $100 deduction was claimed on line 47 and was not included in the Donations variable, line 49.

From 1988 to 1993:
A portion of donations could be claimed as a tax credit. (The Donations variable outlines total donations claimed and not the tax credit portion.) The tax credit available was 17% on the first $250 donated and 29% on donations in excess of $250. As in previous years, there are limits on the amount of donations that can be claimed.

From 1988 to 1995:
A taxfiler could claim the entire amount of charitable donations that were the lower of:

the total donations made in the tax year plus any donations not previously claimed (up to 5 years), or
20% of his or her net income in the current tax year.

From 1994 to present:
A portion of donations could be claimed as a tax credit. (The Donations variable outlines total donations claimed and not the tax credit portion.) From 1994 to 2000, a tax credit of 17% was available on the first $200 donated and 29% on donations in excess of $200. From year 2001 to 2004 the rate was 16%, 15% for 2005, 15.25% for 2006 and 15% for 2007 to present, the inclusion rate on the first $200 was reduced to 16%. As in previous years, there are limits on the amount of donations that can be claimed.

From 1995 to present:
A taxfiler can claim donations made by his or her spouse if not previously claimed.

For 1996:
As outlined above, a portion of donations could be claimed as a tax credit. A taxfiler could claim the entire amount of charitable donations that were the lower of the following 2 items:

the total donations made in the tax year plus any donations not previously claimed (up to 5 years), or
50% of his or her net income (line 236) plus 50% of the taxable capital gains included in his or her income from capital property donated in 1996, minus any capital gains deduction claimed in 1996 on that property (line 339). For the year a person dies and the preceding year, the limit is 100% of the person's net income. Also, a taxfiler receiving income from U.S.A. sources may claim 50% of U.S.A. income from donations made to U.S.A. charitable organizations.

From 1997:
A taxfiler could claim the entire amount of charitable donations that were the lower of the following 2 items:

The total donations made in the tax year, plus any donations not previously claimed (up to 5 years), plus unclaimed gifts to the Crown made in the year or the five preceding years, or
75% of his or her net income for the year, plus 25% of taxable capital gains included in his or her income from capital property donated in 1997, plus income from the recapture of any capital cost allowance arising on gifts of capital property, minus any capital gains deduction claimed in 1997, to the extent it relates to a gift above-mentioned. For the years a person dies or for the preceding year, the limit is 100% of the person's income.

Also, government gifts made after February 18, 1997 to the government of Canada or to a Canadian province or territory are subject to the same rule regarding eligible charitable organizations (75% of net income limitation for 1997).

Government gifts made before February 19, 1997 are not limited to the 75% of net income for 1997. Such gifts are eligible for credit to the extent that the taxfiler has sufficient tax to absorb the amount of credit that the taxfiler produces.

A taxfiler receiving an income from U.S.A. sources may now claim 75% of U.S.A. income for donations made to U.S.A. charitable organizations.

If after July 31, 1997, the taxfiler makes a non-qualifying gift in terms of securities, such as shares of a corporation that a taxfiler controls, obligations or any other securities issued by the taxfiler (other than shares, obligations, other securities listed on a prescribed stock exchange and deposits with financial institutions), the taxfiler may not be able to claim a credit for the donation that is subject to special rules.

From 1998
No major changes.

Educational deduction for full-time student

(1983 to present)

Definition: A full-time student at a designated educational institution and enrolled in a qualifying educational program is entitled to claim an educational deduction. This deduction reduces Taxable income. Since 1988, the educational deduction has been a non-refundable tax credit. Prior to that time, it was a deduction from income.

The following are the educational deductions that a student may claim for each whole or part month that he or she was enrolled in a qualifying educational program:

Educational deduction for full-time student
Table summary
This table displays the results of Educational deduction for full-time student . The information is grouped by Years (appearing as row headers), $ per month (appearing as column headers).
Years	$ per month
1983 to 1987	50
1988 to 1991	60

1998 to 2000	200
2001 to 2005	400
2006 to 2012	465($ 400+$ 65 for textbook amount)

From 1998 to 2000, the education amount the taxfiler could claim monthly was $200. Therefore the maximum amount for this line is $2,400 (12 months x $200). From 2001 to 2005, these amounts are respectively $400 and $4,800. For 2006 to 2012, these amounts are respectively $465 ($400+ $65 for textbook amount) and $5580.

From 1983 to 1987, education amounts transferred from a dependent were claimed on the same line. Only the amount not required to reduce the student's Taxable income to zero may be transferred. From 1988 onward, education amounts transferred from a dependent are claimed on a separate line but not included in the LAD until 1998. Starting in 1999 only the amount transferred by spouse is included.

From 1997, we only keep the qualified total amount of the student in the LAD. However, any unused portion of the educational deduction may be carried forward and claimed in a future year. Any amounts carried forward cannot be transferred to a spouse, parent or grandparent at a later date and are not included in the LAD.

Starting in 1998, there is also an educational deduction available to part-time students ($60.00 per month, line 323). This amount is not included in the LAD for 1998 but is included starting in 1999. (see also EDUDC)

The taxfiler must enter on this line the number of months he or she was a part time student as stated on the T2202 form. The maximum number of months a taxfiler can claim is 12. From 1998 to 2000, the education amount the taxfiler could claim monthly was $60. Therefore the maximum amount for this line is $720 (12 months x $60).

From 2001 to 2005, these amounts are respectively $120 and $1,440. For 2006 to present, these amounts are respectively $140 ($120+ $20 for textbook amount) and $1680. This deduction started being available in 1998, but this variable was only included in the LAD since 1999.

Any portion of the education and tuition credits which the student does not need to claim to reduce his/her federal income tax payable to zero can be transferred.

If a student is married and his/her spouse has claimed the married exemption amount or the amounts transferred from a spouse, then a parent, grandparent, or an otherwise qualified supporting person cannot claim transferred tuition or education credits from the student. The education and tuition amounts can only be transferred to the spouse. The unused portion of the education and tuition credits can only be transferred to one person. It is not divisible between supporting individuals.

LAD: CEDEX I, F, P

Family Allowance received

(1982 to 1992)

Definition: Family Allowance received refers to benefits received from a now defunct universal federal program that provided monthly financial assistance to parents or guardians of dependent children. A parent or guardian who wholly or substantially maintained a dependent child under the age of 18 could apply for Family Allowance and receive the benefit up to and including the month in which the child turned 18. There were restrictions on who was eligible, e.g. residency requirements.

A dependent child was defined as a child with no Taxable income of his or her own until 1988. Beginning in 1988, this stipulation was dropped. This occurred because the Canada Revenue Agency introduced non-refundable tax credits and this changed the method of reporting Taxable income. From 1988 onward, a dependent could have some Taxable income and still receive Family Allowance. Family Allowance received was included as income.

Until 1992, residents of Quebec received Family Allowance (FA___) payments from both the federal and provincial governments. From 1982 to 1986, the sum of the two amounts was reported. From 1987 onward, the provincial payments were non-taxable. This resulted in the provincial payments not being included in the Family Allowance received field, and consequently being excluded from XTIRC. The federal Family Allowance payments to residents of Quebec continued to be reported in this field until 1992.

In 1993, the Child Tax Benefit Program replaced the federal Family Allowance Program. Residents of Quebec continued to receive provincial payments. In 1994, a variable was added to the LAD containing the estimated Family Allowance benefits received by Quebec residents (FAQUE). The benefits are estimated since they are not available from the T1 form. To summarize, Quebec provincial Family Allowance payments are covered by LAD from 1982 to 1986 (in the Family Allowance variable, FA___) and from 1994 to 1996 (in the Quebec Family Allowance variable, FAQUE). Quebec Family Allowance information is not available from 1987 to 1993, and therefore there is some inconsistency in XTIRC.

Beginning in 1989, family allowance was clawed back from higher income families. See Family Allowance repayment, calculated for more information.

See Family benefits, FABEN which contains Family Allowance and family benefits from 1982 to present.

Derived from: Line 118 (1984 to 1992), Line 12 (1982 to 1983)

Definition: Family Allowance repayment calculated refers to the calculated amount of Family Allowance benefits repaid to the government. A new rule was introduced in the 1989 taxation year and applied to taxfilers who received Family Allowance benefits. If a taxfiler had a net income of more than the limit ($50,000 in 1989, $50,850 in 1990, $51,765 in 1991 and $53,215 in 1992), then the taxfiler was required to repay to the government part of the benefits received. Family Allowance repayment calculated is one element of the social benefits repayment field on the T1 General (Line 235).

Derived from: Part of Line 235 (1989 to 1992, also see Line 118). Line 235 is the Social benefits repayment field and consists of the benefits to be repaid on:

Old Age Security pension repayment calculated (1989 to present)
Employment insurance repayment (1989 to present);
Family Allowance repayment calculated (1989 to 1992)
Net federal supplements repayment (1993 to present)

Family Allowance, Quebec

(1994 to 1996)

Definition: This variable contains the estimated benefits received by Quebec residents for Quebec Family Allowance. The benefits are estimated since they are not available from the T1 form. Federal and provincial Family Allowance payments for Quebec residents are covered by the LAD from 1982 to 1986 in Family Allowance (FA__) and, beginning in 1994, in Quebec Family Allowance (FAQUE). Amounts received were not available from 1987 to 1993 resulting in some inconsistency in XTIRC. Quebec Family Allowance (FAQUE) had been merged into Family Allowance benefits (FABEN), and is no longer available as a separate variable.

The Family benefits variable (FABEN) includes the estimated benefits from Family Allowance and family benefits for both federal and provincial programs from 1982 to present.

Derived from: T1FF processing

TIRC_: Not present.

XTIRC: Covered from 1982 to 1986 under Family Allowance (FA___). These payments are not included from 1987 to 1993. Covered from 1994 to 1996 under Quebec Family Allowance (FAQUE). Covered from 1982 to 1986 and 1994 to present in Family benefits (FABEN).

Family benefits

(1982 to 1992 and 1994 to present)

Definition: This variable contains the estimated benefits received from Family Allowance and family benefits from both federal and provincial programs. Outlined below is an historical overview of the evolution of this variable.

1982 to 1992:
Family benefits refer to benefits received from a now defunct Family Allowance federal program that was universally available on a monthly basis to provide financial assistance to parents or guardians of dependent children. A parent or guardian who wholly or substantially maintained a dependent child under 18 could apply for Family Allowance and receive the benefit up to and including the month in which the child turned 18. There were restrictions on who was eligible, e.g. residency requirements. The Family Allowance payments had to be reported as income and were therefore taxable.

A dependent child was defined as a child with no Taxable income of his or her own until 1988. Beginning in 1988, this stipulation was dropped because the Canada Revenue Agency introduced non-refundable tax credits and this changed the method of reporting Taxable income. From 1988 onward, a dependent could have some Taxable income and still receive Family Allowance.

Until 1992, residents of Quebec received Family Allowance (FA_) payments from both the federal and provincial governments. From 1982 to 1986, the sum of the two amounts was reported. From 1987 onward, the provincial payments were non-taxable. As a result, the provincial payments are no longer included in the Family Allowance received field, and consequently excluded from XTIRC. The federal Family Allowance payments to residents of Quebec continued to be reported in this field until 1992.

1993:
In 1993, the Child Tax Benefit (CTBI_) program replaced the federal Family Allowance program. Residents of Quebec continued to receive provincial payments, but this information was unavailable for 1993 and therefore there is some inconsistency in XTIRC.

1994 to present:
Quebec Family Allowance (FAQUE) is included in FABEN. These benefits are estimated since they are not available from the T1 form.

1996 to present:
Family benefits for British Columbia (FABC) is included in FABEN. These benefits consist of the British Columbia Family Bonus. These benefits are estimated since they are not available from the T1 form.

1997 to present:
Family benefits for Alberta and New Brunswick are included in this variable. The Alberta family benefits consist of the Alberta Family Employment Tax Credit. The New Brunswick family benefits consist of the New Brunswick Child Tax Benefit and the Working Income Supplement. These benefits are estimated since they are not available from the T1 form.

1998 to present:
Family benefits for Nova Scotia, Ontario, Saskatchewan and Northwest Territories are included in this variable. The Nova Scotia benefits consist of the Nova Scotia Child Tax Benefit. The Ontario benefits consist of the Child Care Supplement for Working Families. The Saskatchewan benefits consist of the Child Tax Benefit. The Northwest Territories Benefits consist of the Child Benefit and the Territorial Worker's Supplement. These benefits are estimated since they are not available from the T1 form.

1999 to present:
Family benefits for Nunavut is included. These benefits consist of the Child Benefit and the Territorial Worker's Supplement. These benefits are estimated since they are not available from the T1 form.

Family caregiver tax credit for a dependant (claimed)

(2012)

Definition: This variable indicates the amount of the family caregiver tax credit for a dependant, as claimed by the client. If the taxfiler has an eligible dependant, the Family caregiver amount (FCA) allows them to claim an additional amount of $2,000 a tax credit if the dependant has an impairment in a physical or mental function.

Note
The maximum amount for infirm dependants age 18 or older (line 306) includes the additional amount of $2,000 for the FCA.

The dependant with the impairment must be:
- an individual 18 years of age or older and dependent on you because of an impairment in physical or mental functions; or
- a child under 18 years of age, with an impairment in physical or mental functions. The impairment must be prolonged and indefinite and the child must be dependent on you for assistance in attending to personal needs and care when compared to children of the same age.

You must have a signed statement from a medical doctor showing when the impairment began and what the duration of the impairment is expected to be. For children under 18 years of age, the statement should also show that the child, because of an impairment in physical or mental functions, is dependent on others for an indefinite duration. This dependence means they need much more assistance for their personal needs and care compared to children of the same age. You can claim the FCA for more than one eligible dependant.

In 1990, the goods and services tax credit and federal sales tax credit overlapped. In 1991, the federal sales tax credit was completely replaced by the goods and services tax credit. The GST was enacted in 1990 as part of the tax imposed on virtually all personal expenditures beginning January 1, 1991. The GST credit is intended to offset the cost of tax for lower income individuals and families. The GST Credit replaced the FST credit on the 1991 return. Taxfilers could apply for the GST credit on the 1989 and 1990 returns. However, the eligible taxfiler did not receive the first GST credit payment, which is paid tri-annually, until December 1990.

GST rebate for employees and self-employed

(1991 to present)

Definition: This is the amount of GST rebate given to employees and partners (self-employed). A taxfiler that deducted eligible expenses from income may claim a GST rebate if his or her employer (other than listed financial institutions) has a GST number and if he or she files a GST return; or the taxfiler is a member of a registered partnership and reports on the return-form his or her share of income from that partnership. This rebate is reported as income in the year it is received. Therefore, if a taxfiler received a 1993 GST rebate for self employment, it should be included in their 1994 tax return as income.

Definition: To receive this credit, including any related provincial credit, you have to apply for it. Your credit is based on the number of children you have and your net income added to the net income of your spouse or common-law partner (if you have one), minus any amount you or your spouse or common-law partner reported on lines 117 and 125. If you or your spouse or common-law partner deducted an amount on line 213, and/or the amount for a repayment of registered disability savings plan income included on line 232, CRA will add these amounts to you or your spouse's or common-law partner's net income. This information is also used to calculate any payments from certain related provincial programs. Net income is the amount on line 236 of a person's return, or the amount that it would be if the person filed a return.

Over a period of no more than 15 years, the participant must repay to his or her RRSPs the amounts withdrawn under the HBP. A participant's repayment period starts the second year following the year of his or her withdrawals. If the person repays more than the required amount for the year, their HBP amount due for later years will be reduced accordingly. If the person does not repay the amount due for a given year, the outstanding amount (Shortfall amount variable HBPSH on LAD) must be declared as income for that year.

Over a period of no more than 15 years, the participant must repay to his or her RRSPs the amounts withdrawn under the HBP. A participant's repayment period starts 60 days after the end of the second year following the year of his or her first withdrawals. If the person repays more than the required amount for the year, their HBP amount due for later years will be reduced accordingly. If the person does not repay the amount due for a given year, the outstanding amount is the shortfall amount. The shortfall amount must be included in the person's income for that year.

Home Buyer's Plan withdrawal

(2002 to present)

Definition: This is the total amount of withdrawals made under the most recent participation to Home Buyer's Plan. These withdrawals could have been made in any given year from 1992 onward, and do not necessarily reflect a withdrawal in the current tax year. Therefore this variable should not be used to determine current year withdrawal amounts.

The Home Buyer's Plan (HBP) is a program that allows a person to withdraw up to $20,000 from their registered retirement savings plans (RRSPs) to buy or build a qualifying home. However, the program sets out certain conditions for participation. If an individual meets all the applicable HBP conditions, the withdrawals will not have to be included in his or her income, and the RRSP issuer will not withhold tax on these amounts. If a person buys a qualifying home with their spouse or common-law partner, or with other individuals, each person involved can withdraw up to $20,000.

Prior to 1999, an individual could use the Home Buyer's Plan only once in a lifetime. This restriction is eliminated for 1999 and subsequent years such that, once an individual has repaid all the funds withdrawn for a prior home purchase, he or she may use the Plan again commencing with the year following the final repayment, as long as all of the original conditions for HBP participation are, once again, satisfied.

Immigrant's country of last permanent residence

(1980 to present)

Definition: This variable is based on the country of last permanent residence, meaning the country where the immigration applicant has resided on a permanent (or de facto permanent) basis for one year or more. De facto permanent applies to residence in a country that never confers permanent residence (such as "illegal" Chinese in various South East Asian countries) or only after a long period (such as Switzerland).

Exceptions:

a) For a Convention Refugee (CR) or member of any Designated Class (DC), CLPR means the country from which the applicant fled. In the case of Political Prisoners and Oppressed Persons (PPOP) Designated Class, CLPR may be the country in which the refugee is currently living (e.g. Special Programs such as Polish Detainee Program, Salvadorian Political Prisoners and Guatemalan PPOP).

b) Regardless of the time a person has resided in a country, if that person's status is of a temporary nature (foreign student, guest worker, long term visitor) CLPR will be the country where the person resided permanently prior to entering the country of present residence.

CLPR for dependent children of CR/DC applicants should be coded the same as the CLPR of the principal applicant regardless of the country of birth or residence of the child. This applies only to CR and DC cases for dependent children and does not affect the CLPR coding for spouses of CR and DC applicants, which should continue to be determined according to item 10.20(2).

The following countries have been regrouped or restructured compared to the original CLPR variable on the IMDB: England, Scotland, Wales, Northern Ireland and the Channel Islands are classified together under the code for the United Kingdom. Portugal and Azores have separate codes. Spain and Canary Islands have separate codes.

See the listing under the Immigrant's Country of Citizenship at Landing (PAYSC) variable for the country codes associated with this variable.

Income before tax, total (ISD definition)

(1982 to present)

Definition: Total income (TIRC), as found on Line 150 of the T1 tax form, refers to the sum of a taxfiler's income for the Canada Revenue Agency's purpose. ISD modified this variable to create its own definition of total income (XTIRC). It includes the taxfiler's income from taxable as well as non-taxable sources. This definition has changed over the years to reflect changes in the tax form, refundable tax credits, and income calculations. The relationship between the Canada Revenue Agency's and ISD's definition is as follows (see Section 14, Table 4 for a complete list of variables):

XTIRC = TIRC - {adjustment for dividends} - {capital gains} + {refundable tax credits} + {other non-Taxable income}

Total income as defined by ISD is the sum of the following income sources:

Master categorization of immigrant categories

(1980 to 2009)

Definition: This field is a ‘Master categorization' of immigrant categories which allows the user to group IMDB data by custom categories. In layperson's terms, the computer program constructs the categories by translating ‘old Act' categories to ‘new Act' ones and distinguishing between immigrants whose applications were processed abroad or in Canada, whether or not they fall under ‘Special Programs' and whether they are Principle Applicants or not. This ‘Master Categorization' serves as the basis for grouping specific categories into broader groupings, e.g., all applications processed abroad versus processed inland and immigrants processed through ‘Special Programs'.

The first three characters represent code for the immigrant's category of immigration as defined in the Immigration Act.
The fourth character is 1 for those who had their VISA issued abroad and 0 for those who had their VISA issued inland.
The fifth character is 1 if the immigrant was not processed through a special program and 0 if the immigrant was processed through a special program.
The sixth character indicates family status, values are:

1 – if the immigrant is the principle applicant;
2 – if the immigrant is a spouse;
3 – if the immigrant is a dependant (excluding those processed as a result regulation J88 since June 1991);
4 – if the immigrant is a dependent (including only those processed as a result of regulation J88 since 1991);
5 – definition still to be provided by CIC; and
6 – unknown family status.

Non-refundable tax credit, calculated

(1988 to present)

Definition: This field refers to the amount of credit claimed by a taxfiler. It is a percentage of the total non-refundable tax credits, plus a percentage of charitable donations.

Non-refundable tax credits cannot be carried over to other years, with the exception of charitable donations, and they cannot be transferred to the spouse, with the exception of the age amount, pension income credit, disability deduction, and tuition fees and education amount. Medical expenses and, since 1995, charitable donations, can be claimed by either spouse.

Prior to the 1988 tax reform, taxfilers used personal exemptions and deductions to reduce their Taxable income. Since 1988, many of these deductions and exemptions are added together to derive the non-refundable credit, which is used to reduce federal income tax payable. They are called non-refundable because, if these credits exceed the federal income tax payable, the difference is not refundable.

The following credits and exemptions are added together to result in the non-refundable credit:

Age amount (AXMP_)
Amounts for infirm dependants 18 years of age or older (ADPER, not in LAD)
Basic personal amount
Canada or Quebec Pension Plan contributions through employment (CQPPD)
Canada or Quebec Pension Plan contributions through self-employment (CLCPP)
Charitable donations (TOTDN)
Disability amount for self (DISDN)
Disability amount transferred from dependents other than spouse (DISDO)
Education amount for self (EDUDN)
Equivalent-to-spouse amount
Medical expenses (MDEXC)
Pension income amount (PENDC)
Tuition amount for self (TUTDN)
Tuition fees and education amount transferred from children (EDUDF)
Employment insurance premiums (T4EIC)
Provincial Parental Insurance Plan premiums paid (PPIP_)
PPIP premiums payable on employment income (PPIPE)
PPIP premiums payable on self-employment income (PPIPSE)

Non-refundable tax credits

(1982 to present)

Definition: Non-refundable tax credits are the sum of the following variables:

Age amount (AXMP_)
Amounts for infirm dependants 18 years of age or older (ADPER, not in LAD)
Basic personal amount (BPXMP)
Canada or Quebec Pension Plan contributions through employment (CQPPD)
Canada or Quebec Pension Plan contributions through self-employment (CLCPP)
Disability amount for self (DISDN)
Disability amount transferred from dependents other than spouse (DISDO)
Education amount for self (EDUDN)
Equivalent-to-spouse amount
Spousal amount (MXMP_)

PPIP premiums payable on employment income (PPIPE)
PPIP premiums payable on self-employment income (PPIPSE)
Canada Employment Amount (CEA__)
Public transit passes amount (PTPA_)
Adoption expenses (ADEXP)

As described for the variable Non-refundable tax credit, calculated, a portion of these credits is used to reduce federal income tax payable. They are called non-refundable because, if these credits exceed the federal income tax payable, the difference is not refundable.

Prior to 1988, many of the credits listed above were deductions from total income, as exemptions. To create a relatively consistent variable over time, LAD processing created a TOTNO variable from 1982 to 1987, which included the items listed above whenever available on the tax form.

Non-Taxable income

(1986 to present)

Definition: The Non-Taxable income field refers to the income considered for the refundable tax credits, but not included in the calculation of Taxable income.

The income which is treated in this way includes:

Workers' compensation payments (WKCPY)
Net federal supplements (NFSL_)
Social assistance income (SASPY)

These amounts are included in the calculation for means-tested tax credits such as the goods and services tax credit. Also, these amounts are included in a taxfiler's income to determine whether someone else can claim to be dependent of him/her. The Canada Revenue Agency did not separate these items on the T1 General tax form until 1992. Before 1992, they were reported as a sum on the T1 schedule (NTXI_), which was used to apply for the child tax credit and the federal sales tax credit.

For continuity, the Non-Taxable income field (NTXI_) still exists and is the sum of the above three transfer payments (WKCPY, NFSL_, SASPY) which are, since 1992, reported separately on the T1 form and are available on the LAD.

Number of members with a SIN

(1982 to present)

Definition: This variable is a count of the number of individuals within a family (file type = F) or a couple (file type = P) that have a social insurance number (SIN). The SIN is the basis of selection of individuals into the LAD. The probability of a T1FF family (couple) being represented in the LAD is proportional to the number of individuals within the family (couple) that have a SIN. The greater the numbers of people within a family (couple) that have a SIN, the greater the probability this family (couple) will be selected. In addition to increasing the probability of being selected, families or couples with more than one SIN also have a probability of being selected more than once within the LAD.

The Number of members with a SIN variable can be used to equalize the probability of selecting families or couples into a sample. Please see LAD staff regarding the methods of equalizing the representation of families (couples) within a sample.

The years listed indicate periods for which the specific item was listed as a component of other income in the tax guide. The tax guide list, however, is not exhaustive.

Other income for non-filing spouses:

1991 to present: Starting in 1991, non-filing spouses are assigned an income based on the spousal net income for provincial refundable tax credits and the spousal net income for the GST credit reported by their spouse and in the married / spousal amount. If both of these fields are equal to zero, and the non-filing spouse is over 65, then the maximum amount of annual Old Age Security pension (OASP) is imputed to this person. If the two spousal Net Income fields are zero, and the imputed spouse is 65, then an amount of OASP benefits is randomly assigned between 12 different amounts, each representing the OASP benefit that an individual would receive according to his or her month of birth. The benefit is randomly assigned because the birth month is not known.
If at least one of the two spousal net income fields is greater than zero and the marital exemption is greater than zero, the imputed income is calculated from the married / spousal amount field. However, if the marital exemption field is not greater than zero, and the spousal Net income for GST is greater than zero, then the imputed income will be set to equal the amount claimed in the spousal Net income field for GST. All imputed amounts for OASP and Other Income are based on the information received from the filing spouse and the non-filing spouse's record for age (spouse), age (imputed spouse) and OASP monthly benefits.
1986 to 1990: Same as above except the Federal sales tax credit information was used instead of GST credit.
1983 to 1985: Same as above except there was no Federal sales tax credit at that time.
1982: Other income for non-filing spouses was set to zero.

NOTE: The Canada Revenue Agency definition of "other income includes retiring allowances, scholarships, amounts received through a supplementary unemployment benefit plan (Guaranteed Annual Income Plan), payments from income-averaging annuity contracts, as well as all other Taxable income not included elsewhere.

Pension adjustment

(1991 to present)

Definition: The variable represents the taxfiler's pension adjustments. The pension adjustment (TPAJA) is the sum of credits for the year, if any, from deferred profit sharing plans and/or benefit provisions of registered pension plans sponsored by the taxfiler's employer.

The TPAJA is used in calculating the taxfiler's RRSP contribution limit for the following year. The contribution limit is based on a certain percentage of the previous year's earned income up to an annual maximum less a pension adjustment. The maximum amount of RRSP deduction for each year since 1982 is as follows:

Pension income deduction

(1984 to present)

Definition: Pension income deduction is a calculated non-refundable credit that the taxfiler may be able to claim for certain types of pension income. A taxfiler is allowed a tax credit of up to $1000 of pension income. To compute the credit, a taxfiler must first determine the amount of his or her eligible pension income. The lesser of this amount and $1000 is then entered on the tax return creditable amounts. The amounts eligible for the pension income deduction differ depending on the age of the taxfiler at the end of the tax year. Between 1982 and 1988, this field represented a deduction from income. In the 1988 tax reform, this deduction was converted to a non-refundable tax credit.

Postal code

(1982 to present)

Definition: The postal code is a six-character, alphanumeric code that locates the point of delivery of mail addressed to post office customers in Canada. The code itself is divided into the forward sorting area (FSA, first three characters) and the local delivery unit (LDU, last three characters). In most applications, the postal code from the family aggregate level should be used instead of the individual aggregate level.

The family postal code is a more reliable variable as there is a higher probability of having information in this field because the postal code can be selected from those within the family unit. Also, there is an increased likelihood that a residential and not a business address will be selected for the family postal code. When analyzing migration patterns, the individual postal code is recommended. Note that there is a Nunavut family postal code flag for Nunavut (NUNAV).

Postal delivery mode

(1982 to present)

Definition: The delivery mode is a classification of different types of mail delivery in Canada. This variable can be used to identify residential, non-residential, urban, urban fringe, and rural addresses. The delivery modes, as of 2007, are:

A = letter carrier delivery to domestic address
B = letter carrier delivery to apartment building
E = letter carrier delivery to commercial office
G = specific large volume receiver with pick up arrangements
H = rural route delivery
J = general delivery
K = post office box delivery with the postal code identifying a group of boxes
M = post office box delivery with the postal code identifying one box (i.e. large volume receiver)
N = unknown
R = miscellaneous
T = suburban service delivery
W = rural postal code
X = mobile route delivery
Z = retired, for which delmode, while active, is unknown

Delivery modes "W" and "N" are assigned by the Income Statistics Division; the others come directly from Canada Post. This division assigns a "W" for rural postal codes whenever the second position of the postal code is a zero.

An "N" is assigned for an unknown delivery mode for very old postal codes. This division does not accept Canada Post's "Z" delivery mode unless unavoidable, and instead retains the delivery mode type when the postal code was in use.

Postal codes are combined by delivery to represent FSA publication delivery modes (PBDLMD).

Definition: This counts the number of sub-sectors of paid employment activity for the individual according to the 3-digit North-American Industry Classification System (NAICS) of the employers. The data is derived from a linkage between the T4 slips issued for the individual and Statistics Canada's Business Register. For a business with operations in several industrial sub-sectors, the principal sub-sector is chosen (this may not be the sector of activity of the individual). The employment earnings associated with each T4 slip are aggregated by 3-digit NAICS and the two top sub-sectors of paid-employment are stored in Main principal industry sub-sector of employers (NAIC1) and Secondary principal industry sub-sector of employers (NAIC2). The T4 slips issued to individual, number of (T4CNT) variable is also available. People not associated with a T4 slip should have 0 and those associated with the missing NAICS information for the business would have a count of 1.

Definition: Gross professional income is the total income from the practice of an unincorporated profession (e.g. dentists, accountants, doctors, etc.) before costs and expenses are deducted. If the enterprise is a partnership, each partner reports the income of the entire operation.

Note: When this variable is reported for more than one person in a family, the family and parents aggregate levels contain only the amount from one of these persons, the highest value. It has been assumed that when more than one person in the family reports this self-employment income, these family persons are all working for the same business.

Provincial home buyers tax credit

(2012)

Definition: The amount of the Saskatchewan provincial home buyers tax credit, as claimed by the taxfiler. The taxfiler can claim an amount of $10,000 for the purchase of a qualifying home made after December 31, 2011 (date of sale identified in the purchase agreement of the home). A qualifying home must be registered in your and/or your spouse's or common-law partner's name with the Land Titles Registry and must be located in Saskatchewan.

RRSP income

(1988 to present)

Definition: Registered retirement savings plan (RRSP) income represents RRSP withdrawals during the tax year. All amounts withdrawn from an RRSP must be included in the taxfiler's income. An annuity, which has passed to a taxfiler after his or her spouse's death, must be included in income. Annually, the first $1,000 of annuity payments received from an RRSP may be eligible for the pension income tax credit (Line 314). In 1986 and 1987, annuity payments from an RRSP were included in pension and superannuation income. Beginning in 1995, line 129 includes repayments that have not been made to an RRSP under the Home Buyers' Plan (HBP).

The following provides some additional information on the HBP and repayments to this plan. The Home Buyers' Plan enables an individual to withdraw up to $20,000 from his or her RRSP to buy or build a qualifying home. Under the HBP, the individual is required to repay the withdrawal to his or her RRSP within a period of no more than 15 years. The minimum required repayment on an annual basis is 1/15th of the amount withdrawn from the RRSP. If in any year the individual does not repay the amount required for that year, then the amount is included as RRSP income, line 129.

The amount contributed to the spouse's RRSP is added, when applicable, to the amount the taxfiler contributes to his or her RRSP and is recorded on line 208. Information for this variable is only available from 1987 to 1992. Prior to 1987 and subsequent to 1992, taxfilers were still permitted to contribute to their spouse's RRSP, but the amount contributed cannot be established from the information forwarded to Statistics Canada.

Qualifying individuals can contribute to this plan, and the government will make some matching contributions depending on the income level of the contributor. The individual's contributions are deductible to a maximum of $600 per year. The deduction is technically limited to the least of the individual's actual contribution to the plan, $600 per year, and his or her amount deductible for RRSP purposes minus actual RRSP contributions to his or her own and/or a spousal RRSP plan. It is intended that this rule will continue as RRSP contribution limits change.

Definition: This codes the secondary sub-sector of paid employment activity for the individual according to 3-digit North-American Industry Classification System (NAICS) of the employers. The data is derived from a linkage between the T4 slips issued for the individual and Statistics Canada's Business Register. For a business with operations in several industrial sub-sectors, the principal sub-sector is chosen (this may not be the sector of activity of the individual). The employment earnings associated with each T4 slip are aggregated by 3-digit NAICS and the two top sub-sectors of paid-employment are stored in Main principal industry sub-sector of employers (NAIC1) and Secondary principal industry sub-sector of employers (NAIC2). A count of the different industries appearing on at least one slip for the individual shows up in Principal industry sub-sectors of employers, number of (NAICC).

Definition: Each record is assigned a code to represent the gender of the taxfiler. The code is assigned by the Canada Revenue Agency by matching the social insurance number (SIN) reported on the tax return to the SINMASTER, a Human Resources and Social Development Canada (HRSDC) file. This file contains the gender of every person who has received a SIN. Imputed children are not assigned a sex code (their sex code is blank) while imputed spouses are given a sex code opposite to that of their filing spouse. Non-matched taxfilers who have no sex code are assigned one randomly.

Following are the possible codes:

‘ ' (blank) – sex code not identified
‘F' – denotes female

Standard industrial classification code

(1988 to 1992)

Definition: In the Personal Information Section, taxfilers were asked to state the type(s) of work or occupation(s) that they had in the given year. For some taxfilers, primarily the self-employed, the Canada Revenue Agency classified this information by industry using the Standard Industrial Classification Coding System (SICCD). The SICCD classifies establishments engaged in similar types of activities in relation to similar goods and services. Examples are logging camps, coal mines, clothing factories and laundries. This classification has been developed primarily for establishments that are separate operating entities. The degree of accuracy for this field is not known because this field is seldom used. Starting in 2000, more industry information is available for people who receive a T4 slip from an employer.

Tax deducted for OAS required clawback

(1989 to present)

Definition: Tax deducted at source for Old Age Security required clawback as calculated by the system. Old Age Security (OAS) payments are subject to a special recovery to the extent the recipient's net income exceeds this amount. The system taxes back OAS benefits at a 15% rate if the income exceeds the specified income amount. The system of clawing back OAS payments extends to the application of withholding tax, so that where net income for a base period exceeds the current year clawback threshold, OAS payments will be subject to withholding on the potential clawback. For OAS payments made in January-June of the current year, withholding is based on net income in second prior year returns. For OAS payments in July-December of the current year, withholding is based on net income in prior year returns. Amounts withheld from OAS payments should be claimed on the T1 return.

Total amount of spousal and child support payments paid

(1998 to present)

Definition: Total amount of spousal and child support payments paid by the taxfiler in the year. Effective January 1, 1997, the terms "alimony" and "maintenance" have been replaced by the term "support amount". The deductible portion of these payments is written on line 220 (ALMDN). The taxfiler enters on line 230 the total of all deductible and non-deductible support payments for a spouse or common-law partner, or for a child, that they made (or, if you are the payee, that you repaid under a court order) in 2005. Only the deductible amount is claimed on line 220. Most child support payments paid according to a written agreement or court order dated after April 1997, are not deductible. To be allowed a deduction for any support payments made in a year, you must be living apart from the qualified recipient throughout the remainder of the year. A payment which is deductible by you will be included in the income of the recipient. Generally, to be allowed your claim, you should register your written agreement or court order (including any amendments) with CRA.

Total amount of spousal and child support payments received

(1998 to present)

Definition: Total amount of spousal and child support payments received by the taxfiler in the year. Effective May 1, 1997, a new system of taxation has been implemented under which separate treatment is prescribed for payments made on account of child support ("child support payments") and payments made on account of support of the recipient (usually but not always a former spouse or common-law partner; these payments are referred to for convenience as "spousal payments"). Child support payments are not taxable to the recipient or deductible to the payor, whereas support payments for the benefit of the recipient will continue to be taxable to the recipient and deductible to the payor so long as they meet the criteria. There is a general presumption that payments are child support payments unless otherwise identified, and new system agreements which provide for taxable/deductible (as opposed to child support) payments must be registered with the CRA. A taxfiler enters on line 156 the total of all support payments for themselves and/or for a child that they received (or, if you are the payer, the payments that were repaid to you under a court order) in the tax year. Taxfilers enter on line 128 only the taxable amount. In the case where the payments are made for the benefit of the recipient (usually a former spouse/common-law partner) the former system will still apply.

Prior to May 1, 1997 the following applied to determining the taxable amount of spousal and child support received. The taxable portion of this amount is written in the ALMI field. Support payments received were generally taxable if ALL of the following conditions were met:

when the payments were received, the tax filer and the person making the payments were living apart because of a breakdown in the relationship
the payments were made under a court order or written agreement
the payments were made to maintain the tax filer, their children, or both
the payments were an allowance to be paid periodically, such as monthly or quarterly
the payments were made to the tax filer or to someone else on the tax filer's behalf

Working Income Tax Benefit

(2007 to present)

Definition: The Working Income Tax Benefit is a federal refundable tax credit, which is available starting in 2007 and consists of a basic amount and a disability supplement for low-income individuals and families who are already in the workforce and to encourage other Canadians to enter the workforce.

Some provinces/territories have exercised the option to reconfigure the WITB calculation based on specific social and economic realities. So, the calculation is the same for most of the provinces and territories but the basic working income tax benefit factors are special for Quebec, British Columbia and the Nunavut.

The WITB is calculated on Schedule 6 of the federal income tax return and then entered on line 453 on page 4 of the return.

On Schedule 6 of the return, there are three steps to accomplish. The first step is to calculate the filer's working income and the adjusted family net income. The second step is the calculation of the basic WITB according to the factors for the province. The third step is the calculation of the WITB disability supplement if the tax filer is eligible. If the third step is not applicable for the tax filer, then the amount calculated at the end of the step 2 is the amount to report on line 453.

A tax filer eligible for the WITB if:

He/she was 19 years of age or older on December 31; and
Was a resident of Canada for income tax purposes throughout the year.

Exception
If the tax filer is under 19 years of age, he/she may still be eligible for the WITB, if He/she a spouse or common-law partner or an eligible dependant on December 31.

A tax filer is not eligible for the WITB if:

He/she does not have an eligible dependant and isenrolled as a full-time student at a designated educational institution for more than 13 weeks in the year;
He/she was confined to a prison or similar institution for a period of 90 days or more in the year; or
He/she does not have to pay tax in Canada because he/she is an officer or servant of another country, such as a diplomat, or a family member or employee of such person.

For WITB purposes, an eligible spouse at the end of the year is a person who meets all of the following conditions:

is the cohabiting spouse or common-law partner on December 31;
is a resident of Canada throughout the year;
is not enrolled as a full-time student at a designated educational institution for a total of more than 13 weeks in the year, unless he/she has an eligible dependant at the end of the year;
is not confined to a prison or similar institution for a period of 90 days or more during the year; and
is not an officer or servant of another country, such as a diplomat, or a family member or employee of such person.

Family net income is an individual's net income added to the net income of their spouse or common-law partner, minus any amount reported for Universal Child Care Benefit (UCCB , see line 117 of the Income Tax and Benefit Return). Net income is the amount on line 236 of the Income Tax and Benefit Return.

The Working income for a tax year is the total amount of an individual's or family's income for the year from employment and business (excluding losses).

Yukon Federal refundable First Nations abatement

(2010 to present)

Definition: The Government of Canada and the Government of Yukon have concluded personal income tax administration agreements with many self-governing Yukon First Nations. The agreements provide that both the Government of Canada and the Government of Yukon will share the field of personal income tax with self-governing Yukon First Nations. They also provide for the co-ordination of the Personal Income Tax Act of the Self-Governing Yukon First Nation with the federal Income Tax Act and with the Yukon Income Tax Act. This co-ordination is done through the income tax and benefit return of individuals residing on the settlement lands of the self-governing First Nations. The transferred amount is referred to as "Yukon First Nations Tax." Yukon First Nations tax consists of a federal abatement and a Yukon First Nations income tax credit.

The Federal abatement rate is 95% if you lived on one of the following self-governing Yukon First Nation settlement lands at the end of the year: (Vuntut Gwitchin, Tr'ondëk Hwëch'in, Teslin Tlingit, Selkirk, Nacho Nyak Dun, Little Salmon/Carmacks, Champagne et Aishihik)

The Federal abatement rate is 75% if you lived on one of the following self-governing Yukon First Nation settlement lands at the end of the year: ( Ta'an Kwäch'än, Kwanlin Dun, Kluane, Carcross/Tagish)

All individuals who reside within the settlement land of a self-governing Yukon First Nation, including those who are not members of a self-governing Yukon First Nation, have to identify themselves as residents of the settlement land of a particular self-governing Yukon First Nation.

11 Definition of total income variables

This section specifies the exact definitions of the three measures of total income that are available on the LAD, which are:

TIRC: Total income as per Canada Revenue Agency;
XTIRC: Total income as per Statistics Canada; and
MKINC: Market income as per Statistics Canada.

The first measure of total income is TIRC, which is the Canada Revenue Agency Taxation definition of total income as per the T1 form. The second measure, XTIRC, has been derived by the Small Area and Administrative Data Division of Statistics Canada as a more appropriate measure for statistical analysis. The components of income that are included in XTIRC are generally described in Table 1, Components of XTIRC in 2012, while the details are given in Table 5, Definition of XTIRC, 1982 to 2012.

The largest difference between XTIRC and TIRC occurs from 1986 onward because non-Taxable income is added to XTIRC. In 1986, the Government of Canada introduced the Federal Sales Tax (FST) Credit directed at the low-income population. In order to determine eligibility for the FST Credit, filers had to report their non-Taxable income. This was defined as Social Assistance payments, Guaranteed Income Supplement (GIS), Spouse's Allowance (SPA), and Workers' compensation payments. As a result of adding non-Taxable income to XTIRC in 1986, the user is cautioned in comparing pre-1986 values of XTIRC with later values. For example, an increase in XTIRC from 1985 to 1986 may simply reflect the reporting of non-Taxable income on the 1986 T1 form but not on the 1985 T1, i.e. perhaps no increase in income occurred.

Other new differences are the exclusion of RRSP income for people who are less than 65 years old and the inclusion of Indian exempt employment income to TIRC.

Another difference between TIRC and XTIRC is that capital gains are included in the former but not in the latter. The remaining differences are detailed in Table 4, Differences between TIRC and XTIRC.

The third measure of total income available from LAD is market income (MKINC). MKINC is derived from XTIRC by removing government transfer payments. The components of MKINC are generally described in Table 2, Components of MKINC, 1982 to 2012, while Table 6, Definition of MKINC, 1982 to 2012, gives the detailed derivation.

Besides the change to XTIRC in 1986 due to the addition of sales tax credits, changes in tax legislation and in the content of the T1 form itself have resulted in differences in the availability of the components of total income. The trend has been towards greater availability. For example, in 1992, the components of non-Taxable income are reported separately on the T1 form, adding three variables to the LAD: NFSL, denoting net federal supplements (GIS and SPA), WKCPY, denoting Workers' compensation payments, and SASPY denoting social assistance payments. From 1986 to 1991, only the total of these three payments was reported. A history of the changes in XTIRC is given in Table 3, History of Components of XTIRC.

In summary, this part of the LAD Dictionary specifies the components of TIRC, XTIRC, and MKINC for each year of LAD from 1982 to 2012 via:

Table 1 Components of XTIRC, 2012
Table 2 Components of MKINC, 1982 to 2012

Table 3 History of components of XTIRC

1986
As a result of introducing the federal sales tax credit, FST, non-Taxable income is added to XTIRC. Two new variables are added to LAD, Non-Taxable income, NTXI_, and FST credit, GHSTC.

Alimony, separation, or child support payments are reported as a separate field, ALMI_. Previously this income was included in Other income, OI__.

1987
Provincial Family Allowance payments for residents of Quebec become non-taxable. They are no longer included in the Family Allowance received field, FA___, and therefore are no longer included in XTIRC.

1988
RRSP income, T4RSP, is available as a separate field; it was previously included with Other income, OI___. However, XTIRC includes RRSP income for persons aged 65 and over, RRSPO, only.

Net limited partnership income is available as a separate field, LTPI_. It was previously included in Net self-employment income, SEI__, Net rental income, RNET_, or Other income, OI___.

1989
No changes were made.

1990
The goods and services tax (GST) credit is added to LAD through the existing FST credit variable, GHSTC. Since some people were eligible for both the GST and the FST credits in 1990, the amount of both is carried in this one variable.

1991
The FST credit is dropped and is completely replaced by the GST credit.

1992
The components of non-Taxable income are reported separately on the T1 form. Three variables are added to the LAD: net federal supplements, NFSL_; Workers' compensation payments, WKCPY; and social assistance payments, SASPY.

1993
As a result of replacing the federal Family Allowance program with the Child Tax Benefits program, the variable denoting income from Family Allowance, FA___, is discontinued and the variable denoting payments received from the Child Tax Benefit program, CTBI_, is added.^{Note : 4}

A variable denoting estimated provincial Family Allowance payments to residents of Quebec, FAQUE, is added.

1995
No changes were made.

1996
