Bonus Tax Calculator
Calculate the tax withheld on a one-off bonus payment and your net take-home amount after federal tax, provincial tax, CPP, and EI deductions for the 2026 or 2025 tax year.
Key Takeaway
There is no special “bonus tax” in Canada. Bonuses are taxed at your marginal rate as lump-sum payments — but employer withholding may temporarily over-deduct. CPP and EI also apply up to their annual caps.

29.6%How it works: CRA treats bonuses as lump-sum payments. Tax is calculated as the incremental income tax on salary + bonus versus salary alone. CPP and EI are also deducted on the bonus amount, subject to annual maximums. Quebec residents pay a lower EI rate (QPIP applies separately).
How Bonus Tax Works in Canada
The CRA treats bonuses as lump-sum payments. Unlike regular pay, which is taxed on each pay period based on the annualised amount, a bonus is subject to a withholding calculation that compares your total income (salary plus bonus) against your salary alone. The difference in tax between these two amounts is the tax withheld from the bonus. This means the bonus is effectively taxed at your marginal rate — there is no special “bonus tax” in Canada.
Employer withholding: The CRA requires employers to withhold income tax and CPP on bonuses using the bonus (irregular payments) method — comparing the tax on your year-to-date income with and without the bonus. Because this projects your annual income from a single pay period and cannot see credits like RRSP contributions, it can still over- or under-withhold relative to what you actually owe. Any difference is reconciled when you file your T1 return.
CPP contributions: Canada Pension Plan contributions are deducted from your bonus if you have not reached the Year’s Maximum Pensionable Earnings (YMPE) of $74,600 for 2026. The employee rate is 5.95% on pensionable earnings above the $3,500 basic exemption. If your total earnings exceed the YMPE, CPP2 (enhanced) contributions apply at 4% on the portion between $74,600 and $85,000.
EI premiums: Employment Insurance premiums apply to the bonus up to the maximum insurable earnings of $68,900 for 2026. The employee rate is 1.63% outside Quebec. Quebec residents pay a lower EI rate of 1.30% because they contribute to the Quebec Parental Insurance Plan (QPIP) separately, which covers parental and maternity benefits instead of EI.
Why withholding may differ from actual tax: The tax withheld on your bonus may not match what you actually owe. Your employer bases withholding on your year-to-date income and projected annual income, but cannot account for all credits, deductions (such as RRSP contributions), or other income sources. When you file your return, the CRA calculates your actual tax liability on total income, and any overpayment is refunded.

Worked Example
Scenario: You earn $80,000 per year in Ontario and receive a $10,000 bonus. You want to know how much of that bonus you will actually take home.
Step 1 — Federal tax on bonus: On $80,000 salary alone, federal tax is 14% on the first $58,523 = $8,193, plus 20.5% on $21,477 ($80,000 − $58,523) = $4,403. Total federal tax on salary: $12,596. On $90,000 (salary + bonus), federal tax is $8,193 + 20.5% on $31,477 = $14,646. Federal tax on the bonus: $14,646 − $12,596 = $2,050.
Step 2 — Ontario provincial tax on bonus: Ontario taxes $80,000 at 5.05% on the first $53,891 = $2,722, plus 9.15% on $26,109 = $2,389. Total provincial tax on salary: $5,111. On $90,000: $2,722 + 9.15% on $36,109 = $6,027. Provincial tax on the bonus: $6,027 − $5,111 = $916.
Step 3 — CPP on bonus: The YMPE for 2026 is $74,600. At $80,000 salary, you have already maxed out CPP1 contributions. However, CPP2 applies at 4% on earnings between $74,600 and $85,000. Your bonus pushes total earnings from $80,000 to $85,000 (capped), so CPP2 on the bonus is 4% × $5,000 = $200.
Step 4 — EI on bonus: The maximum insurable earnings for 2026 is $68,900. At $80,000 salary, you have already reached the EI cap, so no additional EI is deducted from the bonus: $0.
Total deductions on bonus: $2,050 + $916 + $200 + $0 = $3,166.
Net bonus: $10,000 − $3,166 = $6,834.
Your effective tax rate on the bonus is approximately 31.7%.

Frequently asked questions
How are bonuses taxed in Canada?
There is no special bonus tax rate in Canada. The CRA treats bonuses as lump-sum payments. Your employer adds the bonus to your salary and calculates the incremental federal and provincial income tax at your marginal rate. The difference between the tax on salary alone and tax on salary plus bonus is the tax withheld from the bonus. CPP and EI also apply up to their respective annual caps, and your actual tax on the bonus depends on your total income for the year.
Do I pay CPP on my bonus?
Yes. CPP contributions are deducted from bonus payments if you have not yet reached the Year's Maximum Pensionable Earnings (YMPE) of $74,600 for 2026. The employee CPP rate is 5.95%. If your total earnings exceed the YMPE, CPP2 (enhanced) contributions apply at 4% on earnings between the YMPE and the second ceiling of $85,000. Once you exceed both ceilings, no further CPP is deducted.
Do I pay EI on my bonus?
Yes. Employment Insurance premiums apply to bonus payments up to the maximum insurable earnings of $68,900 for 2026. The employee EI rate is 1.63% outside Quebec. Quebec residents pay a lower EI rate of 1.30% because they contribute to the Quebec Parental Insurance Plan (QPIP) separately. If your salary has already reached the EI cap, no additional EI is withheld from the bonus. Your employer also pays EI premiums at 1.4 times the employee rate.
Is bonus tax different in Quebec?
Quebec has its own provincial income tax administered by Revenu Quebec, separate from the CRA. Quebec residents also pay a lower federal EI rate (1.30% vs 1.63%) because they contribute to the Quebec Parental Insurance Plan (QPIP) instead. The federal tax for Quebec residents is reduced by a 16.5% Quebec Abatement. Provincial tax rates in Quebec range from 14% to 25.75%.
Can I put my bonus in an RRSP to reduce tax?
Yes. Contributing your bonus to an RRSP reduces your taxable income for the year, which can lower or eliminate the tax on the bonus. Your RRSP contribution room for 2026 is 18% of your previous year's earned income, up to the annual maximum of $33,810. If your employer offers a group RRSP, you may be able to contribute before payroll deductions, avoiding withholding tax entirely. Unused room carries forward indefinitely.
Will I get a refund if too much tax was withheld from my bonus?
You may receive a refund when you file your tax return. Employers withhold tax on bonuses using lump-sum rates that may overestimate your actual tax liability. When you file your T1 return, the CRA calculates your actual tax on total income for the year. If withholding exceeded the actual tax owed, the difference is refunded. RRSP contributions, charitable donations, and other deductions can further increase your refund.
How is employer withholding calculated on bonuses?
The CRA requires employers to use the bonus (irregular payments) method: compare the tax on your year-to-date income including the bonus against the tax on your year-to-date income without the bonus. The difference is the tax to withhold. This method effectively applies your marginal tax rate to the bonus. Because it projects annual income from a single pay period, it can still over- or under-withhold relative to your actual liability, reconciled when you file your T1 return.
