2026 Canadian Income Tax Calculator

Canadian income tax has two main parts: federal tax and the tax charged by your province or territory. Both use brackets. Each bracket applies a rate to a slice of taxable income, so moving into a higher bracket does not mean that all your income is taxed at that higher rate. Your province of residence on December 31 generally determines which provincial or territorial return you complete.

Taxable income is not always the same as your salary. Employment earnings, self-employment profit, interest and other income can be treated differently. Eligible deductions, such as amounts you claim for RRSP or FHSA contributions, can reduce the income used to calculate tax. Non-refundable credits then reduce tax, but generally cannot create a refund by themselves.

If you are asking ‘how do I calculate my income tax?’, start with your expected annual income and deductions in this personal tax calculator. Add tax already withheld to estimate a refund or balance owing. The detailed estimate asks about family circumstances, credits and benefits that the quick calculation cannot capture. These are estimates, not a filed return.

Your marginal tax rate is the rate that applies to your next dollar of taxable income. Your average tax rate describes the share of income paid in tax overall. Because lower brackets apply first and credits reduce the bill, the average rate is usually lower than the marginal rate. CPP contributions and EI premiums are separate from income tax, even when all three appear as deductions on your paycheque.

This distinction matters when comparing a raise, additional freelance work or a deductible contribution. A higher bracket does not erase the benefit of earning more. Credits, surtaxes and income-tested benefits can also affect the result, so a bracket table alone cannot predict your final refund. Compare estimates using the same income period and the same assumptions.

A refund generally means you paid more during the year than your final tax bill requires. A larger refund is not automatically a larger tax saving: extra payroll withholding can also increase it. The useful goal is to claim every deduction and credit you actually qualify for while keeping your information complete and accurate.

Gather your contribution receipts, tuition slips, charitable donation receipts, medical expenses and eligible child-care costs. Check your available RRSP deduction limit and FHSA eligibility rather than assuming every contribution is deductible. Self-employed people should keep a clear record of business income and eligible expenses. Never add expenses you cannot support.

Use the detailed personal tax calculator to explore your own circumstances, including a spouse or children, and review benefits separately from your refund. Keep previous notices of assessment and carry-forward information available for filing.
