Bonus Tax Calculator Canada (2026)
Direct answer: Canada has no special bonus tax. A bonus is added to your salary and taxed at your marginal rate. On a $70,000 Ontario salary that rate is about 29.6%, so a $5,000 bonus loses roughly $1,483 to income tax — leaving about $3,518 before CPP and EI. Add your bonus to your salary in the calculator below to see the combined take-home.
Is there a special bonus tax in Canada?
No. Canada has no special bonus tax rate. A bonus is added to your income and taxed at your marginal rate — the same rate as the rest of your salary.
How much tax will I pay on a $5,000 bonus?
At a $70,000 Ontario salary, your marginal rate is about 29.6%, so a $5,000 bonus costs about $1,483 in income tax — plus CPP and EI if you have not maxed them.
Why was so much tax taken off my bonus?
Payroll often uses the CRA bonus method, which can withhold more upfront than your true marginal rate. Any over-withholding comes back as a refund when you file your return.
Do CPP and EI come off a bonus?
Yes, until you reach the annual maximums. A bonus has CPP (5.95%) and EI (1.63%) withheld like regular pay, unless you have already maxed them for the year.

Is there a special bonus tax in Canada?
No. This is the single most common misunderstanding about bonuses. There is no separate, higher tax rate for bonus income in Canada. A bonus, a commission, or a signing bonus is simply added to your employment income for the year and taxed at your marginal rate — the rate on your top dollar of regular salary.
How is tax on a bonus actually calculated?
To estimate the income tax on a bonus:
- Find your marginal rate (the calculator shows it for your salary and province).
- Multiply the bonus by that rate to get the income tax.
- Add CPP (5.95%) and EI (1.63%) if you have not yet maxed them for the year.
- Subtract the total from the bonus for your net.
Why does my paycheque show so much tax on a bonus?
Employers usually run bonuses through the CRA "bonus method", which annualizes the payment to decide withholding. On a one-time bonus this can withhold more than your true marginal rate, especially if the bonus is large relative to a single pay period. The extra is not lost — it is over-withholding that comes back as a refund when you file, or reduces tax owing.
Do CPP and EI apply to bonuses?
Yes, unless you have already reached the annual maximums. A bonus is pensionable and insurable, so CPP and EI are withheld on it just like salary — until your year-to-date earnings cross the $85,000 CPP and $68,900 EI ceilings, after which only income tax applies. This is why a bonus paid early in the year often has more deducted than one paid in December.
How can I estimate my bonus take-home?
The simplest way is to add your expected bonus to your base salary in the calculator above and read the change in take-home. The difference between the two net figures is your bonus take-home. Because the calculator uses your real marginal rate and the 2026 CPP and EI ceilings, it is more accurate than the flat percentage payroll may withhold up front.
