Canada Tax Credits & Deductions Guide for Individuals
Canadian tax returns use deductions and credits that affect calculations in different ways. Federal provisions interact with provincial or territorial tax and benefits. This guide helps you organize common claims, but eligibility, limits and supporting records depend on the specific rule and your circumstances.
Deductions reduce taxable income
A deduction is generally subtracted when calculating taxable income. Potential claims may include qualifying RRSP contributions, childcare expenses, employment expenses or other amounts when statutory conditions are met. The rules are not interchangeable: some require employer certification, a prescribed form or a limit tied to income. Keep documents and check whether the expense belongs to you or another family member.
Credits reduce tax or may be refundable
A non-refundable credit generally reduces tax payable but cannot usually create a refund beyond tax otherwise owing. Refundable credits may be paid when eligibility requirements are met. The federal basic personal amount is delivered through a credit mechanism and has income-related rules; it is not simply a universal tax-free threshold. Medical, tuition, donation, caregiver and disability-related claims each have specific conditions. Provincial and territorial credits differ, while benefits such as the Canada Child Benefit are calculated separately and can depend on adjusted family net income.
| Type | General effect |
|---|---|
| Deduction | Reduces taxable income when permitted |
| Non-refundable credit | Reduces tax payable, generally not below zero |
| Refundable credit | May be paid under eligibility rules |
| Income-tested benefit | Often depends on family income and household details |
Practical checklist
- Collect information slips, contribution receipts and supporting documents.
- Verify eligibility and limits using current CRA instructions for each claim.
- Avoid claiming one expense twice or mixing a deduction with a credit.
- Check provincial or territorial schedules and residence at year end.
- Keep evidence in case CRA requests support after filing.
