9.3.1 Deductions from income

You can deduct certain expenses and other adjustments from your total income to get your taxable income. These deductions reduce the amount of income that you pay tax on, so they reduce your overall income tax. The more deductions that apply to you, the less your taxable income becomes.

Deductions from taxable income are listed on lines 24400 to 25600 of the federal T1 form (see illustration). Review the deductions listed to see any that you think might apply to you.

You can deduct income paid into Registered Pension Plans (RPPs) and Registered retirement savings plans (RRSPs) from both your federal and Quebec tax, up to a limit that is based on the income you have earned in previous years, the amount previously claimed and an annual ceiling. For details, see the section titled Registered Savings Plans.

Other key deductions include:

Normally, you must have receipts for actual expenses or similar documents to claim these deductions, but you don't have to send them in with your tax return.

These deductions are available only when you meet specific conditions, so check the tax guide to be sure that they apply.


Tax deductions reduce your total income to your Taxable Income, line 26000 on the federal T1 tax return and line 299 on the Quebec TP-1.D-V. Taxable Income is used to calculate how much you will receive for federal benefits that are determined by your income, such as the goods and services tax/harmonized sales tax (GST/HST) refund and the Guaranteed Income Supplement. If your Taxable Income is high enough, some benefits are reduced or eliminated entirely—a limit called a clawback.
