Updated Checked by the Tax-Services.ca editorial team How we check
The Canada tax code, as people call it, is really the Income Tax Act plus the rules that hang off it. The Act’s full name is R.S.C. 1985, c. 1 (5th Supp.), and the version on the Justice Laws website is current to 21 September 2026. Your federal tax on 2026 income starts at 14% on the first $58,523 of taxable income.
Is there one Canadian tax code?
No, and that surprises people. There isn’t a single book with that title. Federal income tax sits in the Income Tax Act, and the Income Tax Regulations (C.R.C., c. 945) fill in details the Act leaves to them. The regulations were last amended on 18 June 2026 and are current to 21 September 2026.
Each province adds its own tax on top, with its own brackets. Then there are the CRA’s published interpretations, such as its Income Tax Folios. Those explain how the agency reads the law, but they aren’t the law itself.
The Act is organized in Parts. Part I is the income tax most of us pay. Later Parts cover special cases, from the tax on Old Age Security clawbacks (Part I.2) to rules for non-residents and deferred income plans.
What are the federal rates for 2026?
Here are the federal brackets from the CRA’s 2026 rates page. Each rate applies only to the slice of income inside its bracket.
| Taxable income | Federal rate |
|---|---|
| Up to $58,523 | 14% |
| $58,523 to $117,045 | 20.5% |
| $117,045 to $181,440 | 26% |
| $181,440 to $258,482 | 29% |
| Over $258,482 | 33% |
The basic personal amount is up to $16,452, and it shrinks for higher earners between $181,440 and $258,482. That credit is why you pay no federal tax on your first dollars of income.
How much tax does $80,000 actually produce?
Say you earn an $80,000 salary. Our income tax calculator, which counts the basic personal amount and the CPP and EI credits and nothing else, shows federal tax of $9,242.60. In Ontario the provincial part is $4,885.26, so income tax comes to $14,127.85. That’s an average rate of about 17.7% of pay, well under the 20.5% bracket the last dollars fall in.
Move the same person to Nova Scotia and the provincial part becomes $8,749.03. Total income tax is $17,991.63. Same federal law, different province, a gap of almost $3,900.
Why the gap? Nova Scotia’s 2026 rates run from 8.79% on income up to $30,995 to 21% above $157,124, while Ontario’s lowest rate is 5.05%. That’s how the two levels of government split things, and it’s why you can’t quote “the” tax rate for Canada.
Where do the changes come from?
Rates and credit amounts are indexed, so they move most years. For 2026 the federal indexation factor was 2%. Nova Scotia’s was 1.6%. Budgets add new credits or drop old ones, and a bill has to pass before any change becomes law.
The capital gains inclusion rate is a good case. A proposed rise to two-thirds was cancelled in the Prime Minister’s release of 21 March 2025. We couldn’t find the 2026 inclusion rate printed on a CRA page, so treat the long-standing 50% as our working assumption and check before you sell anything large. The capital gains tax calculator uses 50%.
Where it goes wrong for readers
Most mistakes come from reading a rate off a bracket table and applying it to every dollar you earn. A 20.5% bracket doesn’t mean 20.5% of your income. Pay attention to your marginal rate for new income, such as a bonus or a second job, and your average rate for the whole year. The marginal tax rate calculator shows the first, the income tax calculator shows the second.
Credits are the other trap. Some are refundable, most aren’t, and many are income tested. If you want to see which ones a household might claim, the tax credits calculator covers the federal ones. It doesn’t include provincial credits.
And when a website quotes a rule, ask which year it’s from. Rates from 2023 still float around the internet.
Where the numbers come from
The Act and the regulations are read on the Justice Canada Laws website, current to the dates above. Rates, brackets and the basic amount come from the CRA’s 2026 rates page. Nova Scotia’s rates and 1.6% indexation come from the province’s own personal income tax page. All were rechecked on 30 September 2026. This site isn’t connected with the CRA or any government body.
Frequently asked questions
Is there a single Canada tax code?
No. Federal income tax is set by the Income Tax Act and its regulations, and each province adds its own rules and rates.
What is the lowest federal tax rate in 2026?
14%, on taxable income up to $58,523.
Where can I read the Income Tax Act?
On the Justice Laws website of the Government of Canada, where it is kept up to date.
Do CRA guides count as law?
No. Folios and guides explain how the CRA reads the law, but the Act and regulations are the law itself.
Why does the same income pay different tax in different provinces?
Provinces set their own brackets and credits. On $80,000 our calculator shows $14,127.85 of income tax in Ontario and $17,991.63 in Nova Scotia.
