Updated Checked by the Tax-Services.ca editorial team How we check
Income tax in Canada is charged in slices, first by Ottawa and then by your province, and your employer takes it off each paycheque before you see it. On a $70,000 salary in Ontario, we get about $11,134 in income tax for 2026, plus $5,080 in CPP and EI, which leaves about $53,786 in your pocket.
(We’re assuming you want the general picture for an employee. “Incometax” could mean a few things, and this is the most common one.)
How is income tax worked out, step by step?
Start with your total income for the year: pay, interest, self-employment income and so on. Subtract deductions, like RRSP contributions, and you have taxable income. That’s the number the brackets use.
Next, each bracket taxes only its own slice. The CRA describes this as a progressive system, where rates rise as income rises. Then credits come off the tax itself. The basic personal amount is the biggest, and the CRA calls it a non-refundable tax credit that both Ottawa and the provinces let you claim.
Last, the CRA compares what your employer already withheld with the bill. Too much withheld means a refund. Too little means you owe.
What do the federal brackets do to $69,335?
The CRA’s 2026 tax rates and income brackets page sets the first federal slice at 14% up to $58,523 and the next at 20.5% up to $117,045. Run the taxable income from the table below through them. The first $58,523 at 14% is $8,193.22, and the remaining $10,812 at 20.5% is $2,216.46. That’s about $10,410 before credits.
The federal figure in the table is $7,278, so roughly $3,100 of credits came off the top. The basic personal amount is the largest, and the CPP, EI and employment credits make up most of the rest. This is the step people forget when they try the sum on a napkin and come out too high.
What does a $70,000 salary look like in Ontario?
| Line | Amount, 2026 |
|---|---|
| Gross pay | $70,000 |
| CPP contribution | $3,957 |
| EI premium | $1,123 |
| Taxable income after the enhanced CPP deduction | $69,335 |
| Federal tax | $7,278 |
| Ontario tax, health premium included | $3,856 |
| Left after tax and payroll deductions | $53,786 |
Why is taxable income a bit under $70,000? The part of CPP above the base rate comes off as a deduction, and here that’s $665. EI and the lower slice of CPP work as credits instead. The take-home pay calculator follows the same steps, and the payroll deductions calculator breaks out each line.
Your marginal rate at this income in Ontario comes to about 29.65%. That’s the tax on the next dollar, and it’s a lot higher than the 16% you pay on average, which is why a raise never feels quite as big as you’d hoped.
Which items lower your income tax the most?
Take $2,000 off your income with an RRSP contribution and, at $70,000 in Ontario, the tax falls by roughly $593. Claim a $2,000 credit amount instead and you save $280 federally, plus a smaller provincial piece. Same number, very different result. The first works at your marginal rate, the second at the lowest one.
So if you have a choice, go for the deduction. But you rarely do. Most credits are claimed, not chosen. Check the tax credits calculator for federal credits you might have skipped, and note that it doesn’t cover provincial ones.
Where does the tax on your pay actually go?
Federal and provincial income tax are both collected through the same return for everyone outside Quebec. There, a separate provincial return goes to Revenu Québec. CPP or QPP and EI aren’t income tax, though they come off the same cheque. Employers send the money to the CRA under payroll rules.
Try your own income with the income tax calculator, and switch provinces to see how much the choice of province moves the total.
Mistakes that raise your bill
Forgetting to claim something is the classic. Tuition, medical costs and moving expenses only help if they’re on the return.
Second: treating the withholding as the final answer. Your employer’s tax withholding is an estimate. Add a side job or a big bonus and tax time can bring a bill. And number three is trusting a rough calculator too far. This page leaves out the Ontario LIFT credit, employer benefits, and most credits, so your real figure will differ.
If your income is uneven, the marginal tax rate calculator shows what the next dollar costs. In Ontario near $200,000 it reads unusually high because it counts the health premium.
Sources, and how we checked them
Brackets, the basic personal amount principle and the progressive-tax explanation are taken from the CRA‘s 2026 tax pages. CPP and EI figures follow the CRA’s 2026 payroll rates, and Ontario tax follows the CRA’s January 2026 Ontario payroll tables and the province’s health premium. The $70,000 example was run through this site’s own engine and matches its take-home calculator. Check your notice of assessment for your final figure.
Frequently asked questions
How is income tax calculated in Canada?
Total income minus deductions gives taxable income. Each bracket taxes only its own slice, then credits like the basic personal amount reduce the tax.
Why does a deduction beat a credit of the same size?
Deductions come off income and save you your top rate on the amount. Credits come off the tax itself, at the lowest rate for most basic ones.
Are CPP and EI income tax?
No. They're separate contributions that come off the same paycheque. CPP and EI still earn you tax relief through credits and a deduction.
Why might I owe money even though my employer withheld tax?
Withholding is only an estimate, and extra income can push the real bill above it.
Does Quebec work the same way?
The steps are similar, but Quebec residents file a separate provincial return with Revenu Québec and get a federal abatement.
