Is a bonus taxed at a higher rate than salary?

No. A bonus is taxed at the same marginal rates as salary. However, because a bonus adds to your annual income, it may push part of your total earnings into a higher bracket — so the bonus dollars at the top of your income are taxed at the marginal rate for that bracket, which may be higher than the average rate on your salary. The bonus itself is not subject to a special bonus tax rate.

How much tax will I pay on a $5,000 bonus?

The tax depends on your total annual income and province. If you earn $60,000 in Ontario, a $5,000 bonus brings you to $65,000 — all of the bonus falls in the $57,375-$114,750 federal bracket (20.5%) plus Ontario's provincial rate for that range (~9.15%), for a combined marginal rate of approximately 29.65%. Tax on the $5,000 bonus would be roughly $1,483. Add surtax effects and the actual rate is closer to 31-33%.

What is the bonus method used by employers?

The bonus method (sometimes called the bonus method of withholding) is the CRA-preferred approach described in T4032. The employer calculates the withholding tax by: (1) adding the bonus to the year's expected salary, (2) computing annual tax on the total, (3) subtracting tax already withheld year-to-date. The remaining tax is withheld from the bonus. This method prevents large over- or under-withholding.

Can I put my bonus in an RRSP to reduce tax?

Yes. Contributing your bonus (or an equivalent amount) to an RRSP reduces your taxable income by the contribution amount. If you have RRSP contribution room available, the tax saving equals the contribution multiplied by your combined marginal rate. At a 43% marginal rate, a $10,000 RRSP contribution from a bonus saves $4,300 in tax for the year.

Do CPP and EI apply to bonuses?

CPP and EI apply to bonuses unless you have already reached the annual maximums for the year. In 2025, the CPP maximum is $4,034.10 (employee) and the EI maximum is $1,077.48. If your regular pay through the year has already hit these ceilings, no additional CPP or EI is deducted from the bonus.

Is my employer required to withhold tax on my bonus?

Yes. Under the Income Tax Act, employers must withhold tax from all employment income, including bonuses, using either the bonus method or the regular method. If an employer fails to withhold, the liability falls on the employer, but you are still responsible for reporting and paying the tax on your T1.

What if my employer withholds too much tax on my bonus?

Excess withholding is refunded when you file your T1 tax return. The withholding is only an estimate — your actual tax liability is calculated at year-end based on all income, deductions, and credits. A large bonus withheld at a high rate often produces a refund if your full-year marginal rate is lower than the rate at which the bonus was withheld.

Are signing bonuses taxable in Canada?

Yes. Signing bonuses are employment income under the Income Tax Act and are fully taxable in the year received. If you are required to repay a signing bonus in a future year (e.g., if you leave within a specified period), you may claim a deduction in the year of repayment under paragraph 8(1)(n) of the ITA.

What province has the highest bonus tax rate?

Nova Scotia has the highest combined federal-provincial top marginal rate in Canada at approximately 54% on income above $150,000. Quebec has the second-highest rate at approximately 53.3%. Alberta has the lowest top marginal rate at approximately 48% due to its flat 10% provincial rate and no provincial surtax.

Does a deferred bonus trigger tax in the year of deferral or payment?

Tax arises in the year of constructive receipt — when you have the right to the money without restriction. A bonus formally allocated in December but not payable until January of the following year is generally taxable in January (year of payment), not December (year of allocation). However, a bonus held in escrow that you could have taken in December but chose to defer is taxable in December.

A bonus payment in Canada is fully taxable as employment income in the year received. The tax treatment of bonuses is the same as regular salary under the Income Tax Act — the bonus is added to your total employment income for the year and taxed at your marginal rate. However, the amount withheld by your employer at the time of payment may be calculated using either the bonus method or the regular method, which affects the withholding but not the final tax owing.

Quick Answer

A $10,000 bonus for an Ontario employee earning $80,000 is taxed at the combined federal-provincial marginal rate for income in that bracket — approximately 43.41% in 2025 (26% federal + 11.16% Ontario + 6.25% Ontario surtax threshold effects). The additional tax owing on the $10,000 bonus is approximately $4,341. Your employer’s withholding may differ from this exact amount depending on the method used.

How Bonus Tax Is Calculated

The final tax on a bonus is straightforward: add the bonus to your annual employment income and apply the marginal rate at that combined income level. The marginal rate applies only to the portion of income in each bracket — not to your entire income.

Federal 2025 brackets:
– 15%: $0 to $57,375
– 20.5%: $57,375 to $114,750
– 26%: $114,750 to $177,882
– 29%: $177,882 to $253,414
– 33%: above $253,414

Example: An Ontario employee earning $80,000 receives a $10,000 bonus. Their combined income is $90,000. The bonus falls entirely in the $57,375-$114,750 federal bracket (20.5%) and Ontario’s corresponding bracket. The blended federal + Ontario marginal rate at $90,000 is approximately 43.41%.

The Bonus Method vs. Regular Method

Employers use one of two methods to calculate payroll withholding on bonuses:

Bonus method: Add the bonus to the annual salary, calculate tax on the combined amount, subtract tax already withheld for the year. The remainder is withheld from the bonus. This is the more accurate method and prevents large over- or under-withholding.

Regular method: Add the periodic bonus (annualized as if paid every period) to the regular pay for the period, calculate withholding on the combined amount for that period. This can result in significant over-withholding for large one-time bonuses.

Regardless of the method used, your actual tax liability is calculated at year-end when you file your T1. Any excess withheld is refunded; any shortfall is owed.

Reducing Tax on a Bonus

The most effective strategy for reducing tax on a bonus is contributing it (or an equivalent amount) to an RRSP before or within 60 days of year-end. An RRSP contribution of $10,000 at a 43% marginal rate saves $4,300 in tax. You can also ask CRA to reduce your withholding at source (Form T1213) if you know you will make an RRSP contribution.

CPP and EI are generally not applied to a bonus payment once the annual maximums for the year have been reached. If you have not yet reached the CPP or EI maximum, they will also be deducted from the bonus.

Edge Cases

Signing bonus: Signing bonuses are employment income in the year received. If you repay a signing bonus in a future year, you may be able to deduct it at that point, but the original year’s tax is not amended.

Retention bonus: Same treatment as regular bonus — fully taxable in the year received as employment income.

Deferred bonus: Bonuses that are genuinely deferred to a future tax year are taxable in the year constructively received (when they are available to be taken). A bonus allocated in December but paid in January of the next year is generally taxable in January.

Quebec: Quebec taxes bonuses through Revenu Quebec’s withholding tables. The QPP and QPIP rules differ from federal CPP and EI.
