Summary: The income tax and benefit return (ITBR) is not just a tax form — it is the central mechanism the federal and provincial/territorial governments use to carry out Canada’s system of income redistribution. The article does not explain how to complete each line of the return; instead, it situates the ITBR within the broader policy framework that CVITP volunteers need to understand.
The return provides government with verified information about each individual’s annual income. This information determines both how much income tax a person owes and whether they qualify for income‑tested benefits. Higher‑income individuals generally pay more tax and receive few benefits, while lower‑income individuals pay little or no tax and receive more support. This structure reflects Canada’s approach to reducing income inequality: taxes and transfers partially redistribute income from those who can afford to contribute to those who cannot.
Personal income tax is the federal government’s largest revenue source. Throughout the year, the Canada Revenue Agency (CRA) collects tax from individuals—often through payroll deductions or withholding on investment income—based on estimated amounts owed.
Once the tax year ends, the ITBR becomes the tool for reconciling what was collected with what should have been paid. The return totals all income, subtracts non‑taxable amounts and deductions, calculates theoretical tax owing, and then applies non‑refundable credits and taxes already paid. The result determines whether the individual owes additional tax or receives a refund. The CRA then issues a Notice of Assessment confirming its calculations. For most middle‑ and high‑income households, this reconciliation is the primary purpose of filing.
For low‑income households, the ITBR has a second, equally important function. The income information in the return is used by the CRA and other federal departments to determine eligibility for a wide range of income‑tested benefits. These programs operate on a July–June cycle, and eligibility for the upcoming year depends on the ITBR filed for the previous calendar year.
If a return is not filed by the end of April, benefit payments stop at the end of June because the government lacks updated income information. This is why many CVITP clients—despite having little or no taxable income—are highly motivated to file on time. After processing the return, the CRA issues separate notices outlining eligibility, and payment amounts and schedules for each benefit program.
This article situates the income tax and benefit return (ITBR) within a broader government policy context. It does NOT go into the details of each element of the ITBR. For that, CVITP volunteers are well advised to do their homework on how to prepare the return.
The ITBR – a prerequisite for delivering on government redistribution policies
The ITBR is an essential tool of the federal and many provincial and territorial governments. It is used first to confirm the amount of an individual’s income each year. Based on this information, the government can determine both the amount of income tax to be paid by the individual AND the individual’s eligibility to receive certain benefits.
The higher the income, the greater the income tax to be paid by an individual to the government. The lower the income, the greater the benefits to be received by an individual from the government. Most individuals with higher incomes pay tax on their income but receive little or no benefits. Most individuals with low or no income receive benefits but pay little or no income tax.
This is the nature of the Canadian system, in which there is a partial redistribution of income from those who can afford to pay income tax to those who cannot afford most modern-day conveniences. This is based on an implicit understanding we all have: we contribute to the cost of public goods and services when we can afford to but receive support from those same public goods and services when we cannot. The distribution of income throughout Canada after taxes have been paid in by individuals and benefits have been paid out by government reflects lower income inequality across Canadian society than when based solely on markets, before taxes and government benefits have been paid.[i]
The first half of the ITBR – Income tax
The federal and provincial/territorial governments have many sources of revenue that support the various services and programs they offer residents. Personal income tax is the single most important source of revenue for the federal government, accounting for nearly half of all federal revenues.
The tax collection year runs from January 1 to December 31.[ii] During that time, the Canada Revenue Agency (CRA) of the federal government collects personal income tax on every individual’s taxable income from that year. Examples of taxable income include employment earnings and interest or dividends earned on investments. These amounts are collected in anticipation that they are likely to be the amounts the individual owes the federal government. For example, employers will collect income tax from their employees’ pay and remit it to the CRA.
But once the tax year is over, the federal government embarks on an exercise to confirm that the income tax amounts it has received from the individual for that year are correct.
This reconciliation exercise is run primarily in March and April of the next year. The ITBR is the tool that the federal government uses for this exercise. The purpose of the ITBR is to reconcile the figures for the personal income tax the CRA has already collected from various sources for the individual during the last tax year with the amount of personal income tax the individual should in fact have paid.
In this reconciliation exercise, the return is used initially to total up the amount of income the individual received from all sources during the tax year. Certain compulsory payments (for example, contributions to the Canadian Pension Plan or Employment Insurance premiums) can then be deducted from the total income to arrive at the individual’s net income. Social assistance can then be deducted from the net income to arrive at the individual’s taxable income.
The return includes a calculation of the income tax that would in theory be payable on the individual’s taxable income. However, this is not necessarily their final tax bill.
The individual is entitled to claim various non-refundable tax credits. These are deductions that can be applied against the income tax owed in theory to reduce the amount the individual will pay in practice on their taxable income.[iii] If the individual owes no taxes before the application of these non-refundable tax credits, then the non-refundable tax credits serve no further purpose; in particular, they will not be paid to the individual.[iv] The individual is also entitled to claim all the income tax that was deducted and remitted to the CRA during the tax year.
If the difference between the theoretical amount of tax to be paid and all these deductions is positive, then the individual must pay the difference by April 30th or incur a late filing penalty plus interest on the amount owed. If the difference is negative, then the CRA will issue a refund of the difference to the individual.
Apart from Quebec, every province and territory has agreed that the CRA can also use its income tax return process to calculate and collect the amount of provincial or territorial income tax the individual owes.
Once a return has been filed, the CRA will issue a Notice of Assessment. This document confirms the CRA’s own calculations of the individual’s taxable income, and the refund or balance owed. In many cases, the CRA agrees with the volunteers’ calculations; the Notice of Assessment corresponds with what the volunteer tells the client.
However, in some instances the CRA’s Notice of Assessment will differ. The most common example of this is when the client owes income tax from prior years. This will not be reflected in the volunteer’s calculations as Autofill My Return does not provide this information. But it will show up in the Notice of Assessment.
For many middle and high-income households, this reconciliation exercise completes their returns.
The second half of the ITBR – Benefits
What I’ve described above is only the first half of the story for low-income households.
The income information submitted in the return is then used by the CRA and other federal entities (principally, Employment and Social Development Canada through Service Canada) to determine the individual’s eligibility for various programs designed to help low-income households with various day-to-day costs. Many of these programs are delivered in the form of income support. Many are designed to help reduce income-based poverty, but none are, by themselves, intended to eliminate income poverty.
This is key to understanding the importance of the ITBR preparation process. Many CVITP clients have no or very low taxable income. They may not have much if any income tax to pay. But they make sure to get their returns filed.
This is because these clients know that if they do not, the CRA will not have the income information it needs to determine their ongoing eligibility for these various programs of income support. The net income, not the total or taxable income, reported by the client’s household[v] in their returns is what is usually used to determine eligibility for these programs and the level of support that will be provided.
These programs all run on a 12-month cycle, from July 1st to June 30th of the next calendar year. The eligibility and size of benefits in the next 12-month cycle are based on the information in the ITBR filed for the last calendar/tax year.
If the individual’s income information from the last year is not provided by the end of April, the federal government will stop payments to the individual at the end of June. Thus, most CVITP clients are anxious to get their return filed by the end of April, to ensure no interruption in the benefits they receive from one 12-month cycle to the next.
Based on the income information submitted in the return, the CRA will issue the individual with separate notices for each of the federal and provincial or territorial benefits it administers. These notices will confirm the individual’s eligibility for the benefit, the amount to which they are entitled and the schedule of benefit payments.
Read the second part, entitled What CVITP Clients Need To Know About Their Tax Return.
[i] Statistics Canada reports regularly on income inequality, using a measure called the Gini coefficient. The Gini coefficient is a number between zero and one that measures the relative degree of inequality in the distribution of income. The coefficient would register zero (minimum inequality) for a population in which each person received the same adjusted household income and it would register a coefficient of one (maximum inequality) if one person received all the adjusted household income and the rest received none. Even though a single Gini coefficient value has no simple interpretation, comparisons of the level over time or between populations are very straightforward: the higher the coefficient, the higher the inequality of the distribution. For 2023, the most recent year that Statistics Canada has reported on, Canada’s Gini coefficient for market income was 0.429 and for after tax and benefits income was 0.3.
[ii] The federal government’s fiscal year – a 12-month period that it uses for financial accounting and reporting – runs from April 1 to March 31 of the next calendar year.
[iii] These non-refundable tax credits have multiplied over the years. Together with various refundable tax credits, they have complicated the preparation of the return. Many have been introduced by the federal government because of lobbying by certain interest groups. Thus, their elimination could present the government with political problems.
[iv] The Disability Tax Credit (DTC) is a good example of this. Low-income residents with a valid DTC certificate from the CRA may be able to claim this non-refundable tax credit. But if they have no taxable income, they owe no income tax to begin with. So, the DTC will do nothing to reduce their income tax bill.
[v] The concept of household is used to determine the overall amount of income that is available. An adult living alone is defined as being a household as is a couple living together. A household can also include children under the age of 18 living with one or more parents. Children 18 years of age living with their parents are usually not considered part of the household. So, for example, the GST credit will be based on a single person’s net income. Where two adults are living as a couple, the GST credit will be based on their combined net income. If one or more parents have children under the age of 18 living with them, the GST credit will be based on the net income of the parent(s) but will also take account of the number of children. A child 18 years of age or older who is living with their parents will be considered a separate household so the individual will be eligible to receive the GST credit separately from their parents.
