Marginal tax is what the next dollar you earn costs you, and it’s nearly always higher than the share of your pay that goes to tax overall. Picture $60,000 taxable in Nova Scotia the marginal rate is 35.45%, while the average works out to 20.3%.
What is a marginal tax rate, in plain terms?
Canada taxes income in slices. The first slice is taxed lightly, the next a little more, and so on. Your marginal rate is the rate on the top slice you reach. Nothing already earned gets taxed again at that rate, which is the point people miss when they turn down a raise for fear of a “higher bracket.”
Two layers here. There’s a federal rate and a provincial one, and both apply to the same slice. At $60,000 the federal rate is 20.5%. Add Ontario’s 9.15% and you’re at 29.65%.
What are the marginal rates at common incomes?
Here’s what our engine returns for taxable income, with the basic personal amount claimed and nothing else. Average is total tax over income.
| Taxable income | Province | Marginal rate | Average rate |
|---|---|---|---|
| $60,000 | British Columbia | 28.2% | 15.0% |
| $60,000 | Ontario | 29.65% | 15.7% |
| $60,000 | Nova Scotia | 35.45% | 20.3% |
| $100,000 | Ontario | 31.48% | 21.5% |
| $100,000 | Nova Scotia | 38.0% | 27.1% |
| $150,000 | British Columbia | 40.7% | 25.6% |
| $150,000 | Nova Scotia | 43.5% | 31.9% |
The gap between the two columns is the whole story, and it’s why a quoted top rate sounds so much scarier than the share of your pay that actually goes to tax. Someone at $150,000 in British Columbia pays 40.7% on the next dollar but only 25.6% overall.
Why does Ontario show 31.48% at $100,000?
Because 20.5% plus 9.15% is 29.65%, and that’s not what comes out. Ontario charges a surtax once its own tax passes a set level, and that sits on top of the bracket rate. At $100,000 it’s already in play, which lifts the effective rate on the next dollar to 31.48%. The province also has a health premium that steps up with income, so the marginal rate can jump in odd places.
Our tool reads the rate by testing the tax on the next $100, so surtax and premium steps show up in it. Near $200,000 in Ontario the result can look very high because of the health premium step. Treat any reading right on a step as a jump, not a typical rate. The marginal tax rate calculator runs a few incomes either side of yours.
What does a $5,000 raise really leave you?
Take $60,000 in Nova Scotia. The engine says total tax on $65,000 is $1,824.25 higher than on $60,000. So the $5,000 raise leaves $3,175.75, or about 63.5 cents on the dollar. That’s a bit more than 35.45% because the raise crosses Nova Scotia’s $61,991 line, where the provincial rate goes from 14.95% to 16.67%.
The same raise in British Columbia costs $1,410, and you keep $3,590. Ontario costs $1,482.50 and leaves $3,517.50. All three are before CPP and EI, which come out of a real paycheque as well. For the full picture use the take-home pay calculator, or the bonus tax calculator if it’s a one-time payment.
How can you use your marginal rate?
An RRSP deduction comes off the top of your income, so it saves tax at your marginal rate, not your average. Put $5,000 in at 35.45% and you cut your bill by about $1,772. So the same deposit does more at $100,000 than at $30,000. The RRSP calculator shows how a deposit grows.
The opposite happens with extra income. Side work, overtime and a second job stack on the top slice. If you’re deciding whether extra shifts are worth it, work from the marginal rate, then subtract the parts that aren’t tax.
Where does the marginal rate mislead you?
It ignores benefits. Some income-tested payments shrink as income grows, and that clawback works like extra tax that this figure doesn’t include. Our tool leaves out those benefit reductions, plus every credit except the basic personal amount. It also treats all income as ordinary. Dividends and capital gains are taxed differently, so a dollar of either doesn’t carry the rate in the table.
And be careful with Quebec, where the calculation has its own federal abatement and provincial system. We haven’t tested it for this page.
Where do the numbers come from?
Federal and provincial brackets for 2026 are on the CRA’s current-year tax rates page, and the British Columbia rates match the provincial government’s page. Ontario surtax and health premium data come from our own engine files, which we rechecked on 30 September 2026. This site isn’t connected to the CRA or any government.
Frequently asked questions
What is the difference between marginal and average tax rate?
The marginal rate is the tax on your next dollar. The average rate is your total tax divided by your income, so it's lower.
Can a raise push me into a bracket where I take home less?
No. Only the income above the bracket line is taxed at the higher rate. On a $5,000 raise from $60,000 in Nova Scotia you still keep $3,175.75.
Why is the marginal rate in Ontario higher than the two rates added?
Ontario's surtax applies on top of its own tax once that tax passes a set level, and a health premium steps up with income.
Does an RRSP deduction save tax at my marginal rate?
Yes. The deduction comes off your top slice of income, so it saves tax at that slice's rate.
Does the marginal rate include CPP and EI?
No. Our figures are income tax only. Payroll contributions are extra.
