Canadian Income Tax Calculator

Canada uses a progressive bracket system stacking federal and provincial income tax. You pay two separate taxes: one to the federal government (CRA) and one to your province or territory. The two are combined on a single T1 return for every province except Quebec.

The Basic Personal Amount is a non-refundable tax credit that effectively makes your first portion of income tax-free. The federal BPA is $16,452 for 2026 (tapered down to $14,829 for high earners above the second-top bracket). Each province has its own BPA — Alberta, Manitoba, Quebec and others differ materially from the federal amount.

For 2026 the federal brackets are: 14% on the first $58,523, 20.5% on $58,523–$117,045, 26% on $117,045–$181,440, 29% on $181,440–$258,482, and 33% above $258,482. The lowest federal rate was reduced from 15% to 14% effective 1 July 2025.

Your marginal rate is the tax on your next dollar of income — the rate of your highest bracket (federal + provincial combined). Your average (effective) rate is your total tax divided by your total income, which is always lower because the early brackets and the BPA are taxed at low or zero rates. For example, a $100,000 earner in Ontario sits in a roughly 31.5% marginal bracket but pays an average rate of only about 20.0%. Use the marginal rate to judge an RRSP deduction or a raise; use the average rate to budget.

The most common levers are deductions that reduce taxable income — RRSP contributions, child-care expenses, union/professional dues and moving expenses — plus non-refundable credits (tuition, medical, donations). An RRSP deduction saves tax at your marginal rate, so it is worth most to higher-bracket earners. Income splitting (spousal RRSP, pension splitting) and TFSA growth (tax-free, but not deductible) round out the toolkit.

Use 2025 if you are filing or checking your 2025 T1 return (due in spring 2026; a late return is still accepted). Use 2026 to plan your current take-home pay and RRSP room for the year in progress. The calculator above defaults to 2026; switch the year selector to 2025 for filing.

In every province and territory except Quebec, you file a single T1 return with the CRA that calculates both federal and provincial tax. Quebec residents also file a separate provincial return with Revenu Québec and receive a 16.5% federal abatement on their CRA balance.

Yes. Canadian residents generally report income from inside and outside Canada in Canadian dollars, including foreign employment, investment, pension, rental, and business income. A separate Form T1135 may also be required when specified foreign property costs more than $100,000, but that threshold does not exempt lower-value foreign income from the T1 return.

The Income Tax Act is the federal statute that sets the core rules for income tax liability, taxable income, deductions, credits, capital gains, corporations, trusts, administration, and enforcement. CRA guidance explains how to apply it, while the consolidated Justice Laws text is the legal source.
