# How Canadian income tax works: brackets and credits > How federal and provincial Canadian income tax stack up, what marginal and average rates mean, and how credits and deductions change your bill Canadian income tax has two layers: Ottawa taxes your income, and your province or territory taxes the same income again at its own rates. Quebec runs a separate return. For 2026 the federal rate is 14% on the first $58,523 of taxable income, rising to 33% at the top, and each bracket applies only to the slice of income inside it. ## What's the difference between a marginal and an average rate? Your marginal rate is the tax on your next dollar. Your average rate is your total tax divided by your income. They're rarely the same. People often fear a raise will push them into a bracket where they take home less, but it can't: only the dollars above the line are taxed at the higher rate, and the rest stay where they were. The [marginal tax rate calculator](https://tax-services.ca/calculators/income-tax/marginal-tax-rate) shows yours. The 2026 federal brackets work like this. The first $58,523 is taxed at 14%, the next slice up to $117,045 at 20.5%, and then come 26%, 29% and 33% (the [limits page](https://tax-services.ca/tax-numbers) has the full list, and the CRA's [2026 tax rates and income brackets](https://www.canada.ca/en/revenue-agency/services/tax/individuals/tax-rates-brackets/current-year.html) shows the same table). Say you have $70,000 of taxable income. The first $58,523 costs you $8,193, the remaining $11,477 costs you $2,353, and that's about $10,546 before credits. The basic personal amount of $16,452 then comes off the bill at 14%, a saving of $2,303. Federal tax lands near $8,243. That's an average rate of 11.8%, even though the next dollar you earn is taxed at 20.5% and your province's tax comes on top of both. The [tax brackets page](https://tax-services.ca/canada-tax-brackets) lists the rates for each province. ## How do tax credits and deductions differ? A deduction lowers the income you're taxed on. An RRSP contribution is the classic one, and it saves you your marginal rate on the amount. A non-refundable credit lowers the tax itself, and federally it cuts your tax by 14% of the credit amount in 2026. The [tax credits calculator](https://tax-services.ca/calculators/income-tax/tax-credits) shows what each claim saves. So a deduction matters more as your income rises, while a credit counts for the same amount to everyone who can claim it, whatever they earn. Take the $70,000 example again. A $5,000 RRSP deduction saves about $1,025 in federal tax (20.5% of $5,000), while a $5,000 credit amount saves $700 (14% of $5,000). The [RRSP calculator](https://tax-services.ca/calculators/rrsp-retirement/rrsp-calculator) shows the deduction side with your own figures, and the [TFSA vs RRSP calculator](https://tax-services.ca/calculators/rrsp-retirement/tfsa-vs-rrsp) compares the two accounts. ## What changes by province? Everything on the second layer. Each province sets its own brackets, rates and credits, so $70,000 doesn't produce the same bill in Ontario, Alberta and Nova Scotia. The [province pages](https://tax-services.ca/provinces) sum up the differences. Want one combined figure? Use the [income tax calculator](https://tax-services.ca/calculators/income-tax/income-tax-calculator). ## What else comes off your pay besides income tax? CPP and EI. In 2026 you pay CPP at 5.95% on pay between a $3,500 exemption and $74,600, and EI at 1.63% on pay up to $68,900 outside Quebec. The [take-home pay calculator](https://tax-services.ca/calculators/payroll-salary/take-home-pay-calculator) puts all three together, which is the number that matters when you're checking your paycheque against the offer letter. ## Why doesn't your withholding match your final bill? Your employer takes tax off each paycheque using a standard formula, then your return settles the real figure once credits and deductions are counted. If more came off than you owe, you get a refund. If less, you pay the difference by April 30. A refund means you overpaid during the year. Side income with no withholding is a common reason for a bill; the [side hustle or hobby tax article](https://tax-services.ca/articles/side-hustle-or-hobby-tax-canada) explains where that line sits. ## Related articles on how the tax system works Common beliefs about refunds and brackets are often wrong, and the article on [tax myths in Canada](https://tax-services.ca/articles/tax-myths-canada) takes on several of them. --- Source: https://tax-services.ca/guides/how-canadian-taxes-work Last updated: 2026-10-08 Independent information site.
