Personal Income Tax Deductions in Canada

Canada’s federal and provincial governments use income tax deductions to reduce the tax for some taxpayers and to promote certain activities considered to be beneficial. Some deductions reduce the income subject to tax, while others reduce the amount of the tax directly. As a taxpayer, you should be aware of all the deductions that are available to avoid over-payment.

What Can You Claim On Your Tax Return?

  • basic personal amount that every taxpayer can use
  • age amount
  • disability credits
  • amounts for child care, eligible dependants, and spouse or common-law partner
  • student loan interest
  • medical expenses
  • public transit passes
  • provincial or territorial tax credits

Deductible Expenses

To calculate your tax due, add up your income from all sources. You may be able to deduct expenses from certain types of income, if the expenses represent costs necessary to create the income in the first place.

  • For capital gains declared on Schedule 3, you may have costs or exemptions that you can deduct.
  • For investment income declared on Schedule 4, you often have carrying charges and interest deductions.
  • If you earned self-employed income from a business, as a professional, from a farm or from a fishing operation, you have to fill out Form 2125, Statement of Business or Professional Activities, and deduct your business-related expenses from your income.

If you lost money from any of these activities, you can sometimes deduct the loss from other income.

Deductions That Reduce Taxable Income

Deductions also can be taken after calculating your total income. Governments don’t charge income tax on some of your income and allow you to subtract other amounts, such as RRSP contributions.

You can, for example, deduct money spent on child care and expenses related to employment including moving costs if you change jobs. Your total income minus these deductions equals your net income.

There are a few items you may be able to deduct from the net income because of special circumstances. You could, for example, deduct losses from previous years and an amount if you are a northern resident.

The best strategy for claiming deductions of this type is to go through your income tax form line by line.

If you aren’t sure how to identify a deduction, look at the guide for the line number next to the deduction. The guide explains how to claim the deduction and whether you are eligible.

Deductions That Reduce Income Tax

The Canada Revenue Agency allows you to deduct amounts from the tax that you owe based on your taxable income. You can carry out these calculations on Schedule 1.

There are numerous possible deductions, and while many represent small amounts, they can add up to substantial savings.

Non-refundable vs. Refundable

Tax deductions that reduce your taxable income, or amounts you can subtract from your tax due, are known as non-refundable. This means you can use the deductions to reduce your tax payable to zero, but you can’t claim a refund based on these amounts.

Refundable tax credits, as the name suggests, result in a refund. Normally, you have already paid some income tax, either through salary deductions or via installments paid during the year.

To these amounts, you can add any over payments you made on employment insurance or the government pension plan.

The Working Income Tax Benefit is an example of a refundable tax credit. When the total of these amounts is more than the amount of tax due, or if there is no tax due because the deductions have reduced it to zero, you could receive a refund.
