Canada doesn’t use the word slab, but the idea is the same: your taxable income is cut into slices, and each slice has its own rate. For 2026 the federal slices run from 14% up to 33%, and only the dollars inside a slice are taxed at that slice’s rate.
What are the federal tax slabs for 2026?
Here are the five federal brackets on the CRA’s 2026 rate page. Provinces add their own on top.
| Taxable income | Federal rate |
|---|---|
| $0 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 thresholds are indexed to inflation every year, so they move up a little each January.
What happens right at the edge of a slab?
Try $60,000 of taxable income, just over the first line. The first $58,523 is taxed at 14%, which is $8,193.22. The extra $1,477 is taxed at 20.5%, which is $302.79. Federal tax before credits is $8,496.01, an average of about 14.2%. If the $1,477 had been taxed at 14% it would have been $206.78, so crossing the line cost about $96 more, a few bucks a week, and nothing happened to the first $58,523.
Does earning more ever leave me with less?
No. This is the myth that refuses to die, usually as “a raise pushed me into a higher slab and now I take home less.” A higher slab taxes only the extra dollars at the higher rate. Everything below stays where it was.
There are real cases where a rise in income costs you more than the headline rate suggests, but they come from benefits and credits that shrink as income grows, not from the slab itself.
How do I work out tax on $90,000 in Ontario?
Start with taxable income, which is lower than your pay. On a $90,000 salary in Ontario our engine gets $88,873, because the extra layer of CPP (about 1% of pay above $3,500) comes off as a deduction. Then cut it into slices.
The first $58,523 is taxed at 14%, which is $8,193. The remaining $30,350 sits in the 20.5% slice and adds $6,222. That’s $14,415 before credits. After the basic personal amount and the other credits the engine models, federal tax comes to $11,252. Ontario adds $5,782, so the total is $17,034, an average rate of 18.9% on $90,000.
The rate on your next dollar there is 29.65%, the federal 20.5% plus Ontario’s 9.15%. That’s higher than the 18.9% average, and it’s the number to use when you’re deciding about an RRSP deposit or a side job. The marginal tax rate calculator gives it for your own income.
Which slab am I really in?
Check taxable income, not gross pay. On an $85,000 salary in Ontario the engine shows $15,551 of tax. Add a $5,000 RRSP deduction and it drops to $14,069, a saving of $1,482, or about 30 cents per dollar deducted. That matches the slice those dollars came out of. Put your own deduction in the income tax calculator and compare with the RRSP calculator.
Different income kinds are also taxed differently. Dividends and capital gains don’t work like salary, so try the dividend tax calculator and the capital gains tax calculator for those.
Deduction or credit, which one matters more?
They aren’t the same thing. A deduction shrinks taxable income, so it saves tax at the rate of your top slice. A credit is subtracted from the tax itself. The federal basic personal amount is $16,452 for 2026 and is credited at 14%, so it takes about $2,303 off your federal bill whatever you earn (the amount tapers down at the very top). That’s why a $1,000 deduction helps a person in the 26% slice almost twice as much as one in the 14% slice, while a credit is worth the same to both. The tax credits calculator shows the federal ones.
How big is a full slab?
The second one spans $58,522, from $58,523 to $117,045, so a person who fills all of it pays 20.5% on that whole stretch: about $11,997 before credits. That’s the whole cost of the middle of the income range. If you’re ever unsure which one you’re in, look at taxable income on your return’s taxable income line, not at the T4 box 14 figure.
Limits of a slab table
A slab table shows federal tax before credits. It doesn’t show provincial tax, the Ontario Health Premium, CPP or EI, and it skips the credits that cut the bill. Federal thresholds are the same in every province, but provincial ones aren’t, and they differ a lot.
Sources, and how we checked them
The federal brackets are from the CRA‘s 2026 rates page (page dated June 2026). The worked example comes from our calculator, using 2026 federal and Ontario data. For other provinces, use the calculator or the CRA rate page, since some provincial figures differ between sources.
Frequently asked questions
What is a taxable income slab in Canada?
It's a tax bracket: a band of taxable income with its own rate. Only the dollars inside each band are taxed at that rate.
What are the 2026 federal rates?
14%, 20.5%, 26%, 29% and 33%, with the first break at $58,523 and the last above $258,482.
Can a raise leave me with less pay?
Not because of the bracket. A higher bracket taxes only the extra dollars at the higher rate.
Is taxable income the same as my salary?
No. Deductions such as RRSP contributions and the enhanced CPP part come off first.
Are provincial slabs the same as federal ones?
No. Each province sets its own brackets and rates, and they're added to the federal tax.
