Income Tax Calculator Canada (2026)
How much income tax do you actually pay on $100,000 in Canada? Not 30% of everything: brackets apply in slices, and the basic personal amount shelters the first chunk. This calculator runs the full 2026 federal and provincial bracket calculation for your income and province, then shows your average rate and the marginal rate on your next dollar.
Income tax only, using 2026 brackets and basic personal amount credits, with Ontario surtax and health premium where applicable. CPP, EI, other credits and deductions are not included; your filed return will differ, usually downward, once all credits are claimed.
How it works
Two rates answer two different questions. Your average rate, total tax divided by income, tells you what share of your income goes to income tax overall. Your marginal rate is what the next dollar earned would pay, and it is the rate that matters for decisions like whether an RRSP deduction or an extra contract is worth it.
On $100,000 in Ontario for 2026, this calculator finds $21,520.55 of income tax: an average rate of 21.52%, while the marginal rate on the next dollar is higher, because that dollar lands in a higher slice than most of the dollars below it.

Frequently asked questions
What is the average tax rate on $100,000 in Ontario?
About 21.52% for 2026 under this calculator’s method (basic personal amount credits only), or $21,520.55 of income tax. Claiming all credits available on a real return, such as the Canada employment amount and CPP/EI credits, lowers it further.
What are the federal tax brackets for 2026?
14% up to $58,523, 20.5% to $117,045, 26% to $181,440, 29% to $258,482 and 33% above that. The lowest rate was cut from 15% to 14% in 2025, and the 2026 federal basic personal amount is $16,452.
Why is my marginal rate higher than my average rate?
Because brackets are progressive: your first dollars are sheltered or taxed at the lowest rates, and only the top slice pays your marginal rate. Every decision about one more dollar, a bonus, an RRSP deduction, uses the marginal rate.
Does this include CPP and EI?
No. This is an income tax calculator. CPP (maximum $4,230.45 plus up to $416 of CPP2 in 2026) and EI (maximum $1,123.07) are separate payroll deductions, shown in our Salary Calculator.
How can I lower my income tax legally?
The main levers are deductions and credits you qualify for: RRSP contributions, childcare expenses, moving expenses for work, carrying charges, and credits such as medical expenses and donations. Timing income and using a TFSA for investment growth also help.
