Your marginal tax rate — the tax on your next dollar — is the single most useful number in Canadian personal finance. It sets the value of every RRSP deduction, the tax on every bonus, and whether realizing a gain this year or next is smarter.
Two changes define 2026: the lowest federal rate dropped to 14% (from 15%), and all brackets are indexed for inflation. Combined Ontario marginal rates now run from 19.05% to 53.53%.
The 2026 brackets
| Federal taxable income | Federal rate | Ontario taxable income | Ontario rate |
|---|---|---|---|
| Up to $58,523 | 14% | Up to $53,891 | 5.05% |
| $58,523–$117,045 | 20.5% | $53,891–$107,785 | 9.15% |
| $117,045–$181,440 | 26% | $107,785–$150,000 | 11.16% |
| $181,440–$258,482 | 29% | $150,000–$220,000 | 12.16% |
| Over $258,482 | 33% | Over $220,000 | 13.16% |
Basic personal amounts shelter the first slice: $16,452 federally and $12,989 in Ontario for 2026. Ontario also applies surtaxes at higher incomes, which is why the combined top rate reaches 53.53%.
Marginal vs. average: the myth that costs people money
Crossing into a higher bracket does not tax all your income at the higher rate — only the dollars above the line. Someone earning $60,000 pays 19.05% combined on most of it and 29.65% only on the slice above ~$58,500. Your average rate (total tax ÷ total income) is always lower than your marginal rate — and it is the marginal rate that governs every next-dollar decision.
Three decisions your marginal rate makes
- RRSP vs. TFSA: contribute to the RRSP when your marginal rate is high (the deduction is worth more); prefer the TFSA when it is low or you expect higher rates in retirement.
- Bonus timing: a bonus pushed into January lands in next year's income — useful if this year was unusually high.
- Capital gains timing: realizing a gain in a low-income year (sabbatical, parental leave, early retirement) can save thousands versus a peak-earning year.
2026 change to note: the federal lowest-bracket cut to 14% is the first full year at the new rate — and non-refundable credits (basic personal amount, age amount) are now valued at 14%, making them slightly less valuable than before.
Frequently asked questions
What are the Ontario tax brackets for 2026?
Ontario: 5.05% to $53,891, 9.15% to $107,785, 11.16% to $150,000, 12.16% to $220,000, 13.16% above. Federal: 14% to $58,523, 20.5% to $117,045, 26% to $181,440, 29% to $258,482, 33% above.
What is the top marginal tax rate in Ontario in 2026?
53.53% combined (33% federal + 13.16% Ontario + Ontario surtaxes) on income above $258,482.
Does moving into a higher tax bracket tax all my income more?
No. Only income above the threshold is taxed at the higher rate — earlier dollars keep their lower rates. This is the most common tax myth in Canada.
How does my marginal rate affect RRSP contributions?
At a 30% marginal rate, a $10,000 RRSP contribution saves about $3,000 in tax. Higher marginal rate = more valuable deduction.
