Ontario’s highest tax bracket for 2026 starts at $220,000 of taxable income, where the provincial rate reaches 13.16%. That is only part of the picture. Once Ontario’s surtax and federal income tax are layered on, the true top marginal rate on ordinary income climbs to 53.53% on every dollar above $258,482.1Canada Revenue Agency.

The Five Ontario Brackets for 2026
Ontario applies five provincial brackets, each indexed to inflation by 1.9% from the prior year:1Canada Revenue Agency. Payroll Deductions Tables – CPP, EI, and Income Tax Deductions – Ontario
- First $53,891: 5.05%
- $53,891 to $107,785: 9.15%
- $107,785 to $150,000: 11.16%
- $150,000 to $220,000: 12.16%
- Over $220,000: 13.16%
The $220,000 line is where the top provincial bracket begins. Every dollar of taxable income above it is charged 13.16% by the province before anything else is added.
The Federal Brackets Stack on Top
Ontario residents also owe federal tax, calculated separately on the same taxable income. For 2026, the CRA uses these federal brackets:2Canada Revenue Agency. Tax Rates and Income Brackets for Individuals
- First $58,523: 15%
- $58,523 to $117,045: 20.5%
- $117,045 to $181,440: 26%
- $181,440 to $258,482: 29%
- Over $258,482: 33%
The federal top bracket starts at $258,482, not $220,000. That gap matters. Someone earning $240,000 is already in Ontario’s top provincial bracket but still in the 29% federal bracket. The full combined top rate only takes hold once income crosses $258,482, where both governments are charging their maximum rate at the same time.3Canada Revenue Agency.

How Ontario’s Surtax Pushes 13.16% Higher
Ontario’s surtax is a tax on tax. It applies not to your income directly, but to the amount of basic provincial tax you owe. For 2026 there are two layers:1Canada Revenue Agency. Payroll Deductions Tables – CPP, EI, and Income Tax Deductions – Ontario
- A 20% surtax on basic provincial tax above $5,818
- A 36% surtax on basic provincial tax above $7,446, stacked on top of the 20%
Once your provincial tax exceeds $7,446, both surtaxes apply together for a combined surtax rate of 56%. The 13.16% base rate is effectively multiplied by 1.56, producing a real provincial rate of roughly 20.53% at the top. This is one of the biggest reasons the stated bracket rate understates what a high earner actually pays. The surtax thresholds are not indexed as aggressively as the bracket thresholds, so more earners drift into surtax territory over time. For anyone solidly in the top bracket, the surtax is unavoidable.
Building the 53.53% Combined Top Rate
Here is how the parts add up on every dollar above $258,482:
- Federal tax: 33%
- Ontario base tax: 13.16%
- Ontario surtax effect: 13.16% × 0.56 ≈ 7.37%
- Total: 53.53%
This rate applies to ordinary income: employment earnings, business income, and interest. Capital gains and eligible dividends are taxed at different effective rates because of the capital gains inclusion rate and the dividend gross-up and credit system, so the 53.53% figure does not describe those sources.1Canada Revenue Agency.

What “Top Bracket” Actually Means for Your Tax Bill
A common misread of the top bracket is that crossing $220,000 or $258,482 pushes your entire income to the higher rate. It does not. Each bracket applies only to income within its range. Earning one dollar above $220,000 does not retroactively re-tax the first $220,000. That extra dollar is taxed at 13.16% provincially; everything below it stays at the same lower rates as before.4Canada Revenue Agency. Learn About Progressive Tax Rates and Income Brackets
Your total tax is a blended average across every bracket your income passes through. Someone earning $260,000 pays 5.05% on the first $53,891, then 9.15% on the next slice, and so on up the ladder. Their effective rate on total income is well below the 53.53% top marginal rate. A raise that puts you into a new bracket never costs you more in tax than the raise itself is worth.
Cutting Taxable Income at the Top
Because every dollar above $258,482 faces a combined 53.53%, deductions are worth more at this level than anywhere else on the income scale. The most common tool is the Registered Retirement Savings Plan. For 2026, the maximum RRSP contribution room is the lesser of 18% of your previous year’s earned income or $33,810, plus any unused room carried forward. A maximum RRSP contribution at the top marginal rate saves roughly $18,100 in combined tax on that year’s return.
Other options include the Tax-Free Savings Account (which shelters investment growth rather than reducing current taxable income), charitable donations (which generate federal and provincial credits at enhanced rates on amounts above $200), and pension income splitting with a spouse after age 65. Every dollar of deduction at the top bracket is worth more than 53 cents in tax saved, which is why planning pays off disproportionately once you are in this range.
The Ontario Health Premium
Ontario also charges a health premium based on taxable income. It is not technically an income tax rate, but it appears on your return and adds to your total obligation. For 2026, the premium reaches its maximum of $900 once taxable income exceeds $200,000.1Canada Revenue Agency. Payroll Deductions Tables – CPP, EI, and Income Tax Deductions – Ontario The premium phases in gradually between $20,000 and $200,000. For anyone at or near the top bracket, the $900 is a fixed cost, so its effect on the marginal rate is negligible. It is one more line item to expect, not a change to the 53.53% figure.
