How Canadian income tax brackets work
Last updated
A tax bracket is a slice of taxable income, not a label for your whole salary. The rate for a bracket applies only to the dollars inside it. The dollars below that slice keep the lower rates.
For 2026 the federal brackets start at 14% and step up through 20.5%, 26%, 29% and 33%. The thresholds are published by the Canada Revenue Agency for income earned in 2026. Provinces and territories add their own brackets on top. Quebec sets its own provincial brackets through Revenu Québec, and Quebec residents also receive a 16.5% abatement of basic federal tax.
Marginal rate is not the same as your average rate
If a raise pushes you into a higher bracket, only the part of taxable income above the threshold is taxed at the new rate. Your average tax rate — total income tax divided by income — is lower than the rate on the last dollar.
Credits change the bill again. The federal basic personal amount and the Canada employment amount are non-refundable credits. They reduce tax; they are not a second bracket. Payroll deductions for CPP, CPP2 and EI come off a paycheque as well, and only part of the CPP contribution is a credit. The rest is a deduction in the taxable-income estimate used on the paycheque calculator.
What a bracket table leaves out
A bracket table does not know about a spouse, dependants, tuition, donations, or benefits such as the GST/HST credit. Ontario adds a surtax and a health premium. British Columbia has a tax reduction at lower incomes. Those adjustments are why two people in the same bracket can owe different amounts.
Methodology
This guide describes the bracket structure. It does not compute your tax. The live brackets and the worked numbers are rendered from the same 2026 data files as the calculators, which cite the CRA pages above. Where a provincial figure is unresolved, the calculator page says TODO-verify.
