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 on the Justice Laws website, 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.
You don’t need to read it cover to cover. Almost nobody has. Most people meet the Act through the CRA’s guides and the tax return itself, and only reach for the statute when a guide and a notice disagree.
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.
Think of two friends with the same pay, one in Halifax and one in Hamilton. On pay day the Halifax friend’s take-home looks noticeably lighter, and nobody did anything wrong. It’s the province.
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. The CRA pages we read show one half through 2025, and Finance Canada’s release of September 15, 2026 lists the cancellation of the proposed increase, so the long-standing 50% stands for 2026. 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. For a plain-language map of how it all fits, our guide to how Canadian taxes work is a gentler place to start than the statute.
Which part of the system answers which question?
If you want to know what the law says, that’s the Act and the regulations. If you want to know how the CRA applies it, that’s the folios and guides. If you want to know what you personally owe, that’s your notice of assessment. When two of those disagree, the notice is what you deal with first, and you can object to it if you think it’s wrong.
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. No government body has reviewed or endorsed what you read here.
Frequently asked questions
Is there a single Canada tax code?
No. There is no single book with that title. Federal income tax is set by the Income Tax Act and the Income Tax Regulations, and each province adds its own tax with its own brackets on top. The CRA also publishes guides and folios that explain how it applies the law, but those are not the law itself.
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. The version there was current to 21 September 2026 when we rechecked it on 30 September 2026, and the regulations are on the same site. Most people meet the Act through CRA guides and the return itself.
Do CRA guides count as law?
No. Income Tax Folios and guides explain how the CRA reads the law, but the Act and regulations are the law itself. What you personally owe is shown on your notice of assessment. If a guide and your notice disagree, you deal with the notice first, and you can object to it if you think it is wrong.
Why does the same income pay different tax in different provinces?
Provinces set their own brackets and credits on top of the same federal law. On $80,000 our calculator shows $14,127.85 of income tax in Ontario and $17,991.63 in Nova Scotia, a gap of almost $3,900. Nova Scotia's rates run from 8.79% to 21%, while Ontario's lowest rate is 5.05%.
What are the federal tax rates for 2026?
Federal tax on 2026 income is 14% up to $58,523 of taxable income, 20.5% to $117,045, 26% to $181,440, 29% to $258,482 and 33% above that. Each rate applies only to the slice of income inside its bracket, so a 20.5% bracket does not mean 20.5% of your whole income. The rates come from the CRA's 2026 rates page.
