Ontario Income Tax 2026: A Practical Guide
Understand how federal and Ontario provincial income tax interact for Ontario residents.
How the two systems combine
As an Ontario resident you pay two income taxes: federal (14%–33% for 2026) and Ontario provincial (5.05%–13.16%, plus surtax). Each is calculated on your taxable income separately, then added together. Credits — most importantly the basic personal amounts ($16,452 federal, $12,989 Ontario for 2026) — reduce the bill after the rates are applied.
Worked example: $80,000 in Ontario (2026)
Simplified estimate, no other credits or deductions:
| Federal | Ontario | |
|---|---|---|
| Tax on $80,000 | ≈ $10,293 | ≈ $4,455 |
| Combined income tax | ≈ $14,747 | |
| Average rate | ≈ 18.4% | |
| Combined marginal rate | 29.65% | |
Ontario's surtax doesn't apply here yet — provincial tax of about $4,455 is below the $5,818 surtax threshold. It starts biting around $95,000 of taxable income.
Paycheque vs. tax return
Your employer withholds tax, CPP and EI from each paycheque using CRA payroll tables — that's an estimate. Your actual tax is settled when you file: over-withholding comes back as a refund, under-withholding means a balance owing. RRSP contributions, medical expenses and other deductions claimed on the return are the most common reasons the two differ.
Key points
- Federal + provincial taxes are computed separately, then added.
- Basic personal amounts shelter the first $16,452 federally and $12,989 provincially (2026).
- Payroll deductions are estimates; the tax return settles the real bill.
- Figures are simplified 2026 estimates. Confirm with CRA sources.

Seeing the same math at two income levels shows how progressivity works. Simplified 2026 estimates, income tax only (before CPP/EI), standard credits:
| $60,000 | $100,000 | |
|---|---|---|
| Federal tax | ≈ $6,193 | ≈ $14,393 |
| Ontario tax | ≈ $2,625 | ≈ $6,378* |
| Combined income tax | ≈ $8,818 | ≈ $20,771 |
| Average income-tax rate | ≈ 14.7% | ≈ 20.8% |
*Includes about $93 of Ontario surtax: at $100,000 the provincial tax bill crosses the $5,818 surtax threshold, adding 20% on the excess. The $60,000 case stays below it, so no surtax applies — one reason the average rate jumps faster than the brackets alone suggest.
The $100,000 earner makes 67% more but pays about 136% more income tax. That is progressivity doing its job: each extra dollar is taxed more heavily than the last, while the first dollars stay lightly taxed for everyone.
FAQ
If I contribute $5,000 to my RRSP, how much tax do I actually save?
It depends on your marginal rate: at $80,000 (29.65% combined) a $5,000 RRSP contribution saves roughly $1,482.50 in tax; at $100,000 (31.66%) it saves about $1,583. The contribution reduces your taxable income dollar for dollar, so the saving equals contribution × your marginal rate — one reason higher earners get more value per RRSP dollar.
Do I pay 20.5% federal tax on my whole $60,000?
No. Only the $1,477 above the $58,523 threshold faces 20.5%. The first $58,523 is taxed at 14%, and the $16,452 basic personal amount wipes out tax on the first dollars entirely via a credit.
Why is the $100,000 average rate so much higher than at $60,000?
Three compounding effects: more income sits in the 20.5% federal bracket, more sits in Ontario's 9.15% bracket, and the Ontario surtax starts adding ~$93. Average rates rise with income even though the first dollars are taxed identically.
Why does my refund differ from the calculator estimate?
Calculators use the standard brackets and basic credits. Your return also reflects RRSP deductions, medical credits, tuition, donations and benefit repayments — any of which move the final number.
