Your taxable income in Ontario is your total income for the year minus the deductions the tax return allows. It is not your pay stub number. On an $80,000 salary, the calculator lands on $79,073, because $927 of CPP contributions comes off first.
What counts as taxable income in Ontario?
Start with everything that lands on your return as income: employment pay, self-employment profit, interest, rent after costs, pension income, and half of any capital gain. Dividends come in grossed up, which surprises people. That’s line one, and it’s the easy part.
Line two is deductions. These reduce the income the brackets act on, so they’re worth more than credits of the same size. Common ones are RRSP contributions, the extra CPP contribution, union dues, child care costs and moving costs for a work move. Ontario doesn’t have its own taxable income. You work out one figure on the federal return, and Ontario’s brackets apply to that same number, so one deduction lowers both bills, the federal one and the Ontario one.
Credits work differently, and this trips up more people than any bracket does. The basic personal amount, for example, doesn’t shrink taxable income. It reduces the tax bill after the brackets have done their work, so don’t subtract it yourself.
Which brackets apply to your taxable income?
Both governments tax slices of income at rising rates. The rates below are the 2026 figures on the Canada Revenue Agency’s rates page.
| Slice of taxable income | Federal rate | Ontario slice | Ontario rate |
|---|---|---|---|
| Up to $58,523 | 14% | Up to $53,891 | 5.05% |
| $58,523 to $117,045 | 20.5% | $53,891 to $107,785 | 9.15% |
| $117,045 to $181,440 | 26% | $107,785 to $150,000 | 11.16% |
| $181,440 to $258,482 | 29% | $150,000 to $220,000 | 12.16% |
| Over $258,482 | 33% | Over $220,000 | 13.16% |
The two sets of lines don’t match up. Someone at $60,000 is in the second federal slice but still in the first Ontario one. Ontario also adds a health premium and, at higher incomes, a surtax, and the calculator includes both.
How much does an RRSP change taxable income in Ontario?
Take a salary of $80,000. The income tax calculator shows this:
| No RRSP | $5,000 RRSP | |
|---|---|---|
| Income | $80,000 | $80,000 |
| Taxable income | $79,073 | $74,073 |
| Federal tax | $9,242.60 | $8,217.60 |
| Ontario tax | $4,885.26 | $4,427.76 |
| Total tax | $14,127.85 | $12,645.35 |
So the $5,000 contribution cuts the bill by $1,482.50. That’s about 30 cents per dollar, because those dollars sat in the 20.5% federal slice and the 9.15% Ontario one. Someone earning $45,000 would get less back per dollar, since more of their income sits in the lower slices. Run your own numbers in the RRSP calculator before you borrow to top up a contribution.
The federal and Ontario totals in the table are after the basic credits, the CPP and EI credits and the Canada employment amount. Those don’t show up in taxable income, but they’re inside the tax figures.
Why doesn’t my taxable income match my T4?
Box 14 of the T4 shows employment income. Box 22 shows tax already deducted. Neither is taxable income. The line on your return that does is called taxable income, and you’ll find it near the end of the return and on your notice of assessment.
The gap between the T4 and that line is usually deductions you claimed. It can also go the other way. If you earned interest, side income or a taxable benefit, the total grows. A few hundred dollars of difference is normal. Thousands is worth checking slip by slip, starting with a missing T5 or an RRSP receipt filed in the wrong year.
Mistakes that catch people out
The most common one is treating a bracket as if it taxed all your income. Crossing into the 9.15% Ontario slice taxes only the dollars above $53,891 at that rate. Nothing you earned below it changes.
Another is claiming a deduction twice. Child care can go on only one spouse’s return, and the RRSP receipt has to match the year you claim it in. And people often forget that self-employed people pay both halves of CPP. The self-employed tax calculator lowers income tax for the deductions you enter, but not the CPP, and it leaves out EI, so treat its result as a floor.
If you’d rather see the rate on your next dollar, use the marginal tax rate calculator. Near $200,000 in Ontario it can read very high because of the health premium step. That’s a real jump in the tax formula, but it isn’t a permanent rate.
Where the numbers come from
Brackets are from the Canada Revenue Agency’s 2026 tax rates page. The calculators use the 2026 figures for CPP and EI. These are estimates for a normal employee or freelancer. They aren’t a filed return, and this site has no link with the CRA or the Ontario government.
Frequently asked questions
Is taxable income the same as gross pay?
No. It's your total income minus deductions such as RRSP contributions and the extra CPP contribution. Credits come off the tax, not the income.
Does Ontario have its own taxable income figure?
No. You work out one figure on your federal return, and both the federal and Ontario brackets apply to it.
Where do I find my taxable income?
On your notice of assessment and on the taxable income line of your return. It's also in your CRA account after you file.
Do credits reduce taxable income?
No. Credits like the basic personal amount reduce the tax after the brackets are applied.
What is the top Ontario rate for 2026?
13.16% on taxable income over $220,000, according to the CRA rates page. Federal 33% applies above $258,482.
