ⓘ Bonus tax withholding uses the "bonus method" where the bonus is added to regular pay for the period, tax is calculated on the total, and the difference is withheld. Actual tax owed depends on your total annual income and may differ at tax time.
Frequently Asked Questions
How are bonuses taxed differently than regular income in Ontario?
Bonuses are taxed at the same rates as regular income, but withholding is calculated differently. Employers use the "bonus method" where your bonus is added to your regular pay for that period, tax is calculated on the combined amount, and the incremental tax is withheld from the bonus. This often results in higher withholding rates than your actual annual tax rate. Insight Accounting CPA in Mississauga helps GTA professionals optimize their compensation structures to minimize tax impact across Ontario.
Will I get some of my bonus tax back when I file my return?
If the withholding on your bonus pushes your total deductions above your actual tax liability for the year, yes — you'll receive a refund when you file your T1 return. This commonly happens when bonuses are paid early in the year or when you have significant deductions and credits. Our Toronto-area CPA firm provides year-end tax planning to help Ontario residents maximize their refunds and minimize surprises at tax time.
Do CPP and EI apply to bonuses in Canada?
Yes. Bonuses are considered pensionable and insurable earnings, so CPP (5.95% in 2026 up to the annual maximum) and EI (1.62% for employees in 2026 up to the maximum) are deducted. Once you've reached the annual maximums through regular pay, no additional CPP or EI is withheld from bonuses. Insight Accounting serves businesses across Mississauga, Toronto, and the GTA with payroll compliance and planning strategies.
Should I take my bonus as salary or dividend if I own a corporation in Ontario?
The answer depends on your total income, corporate tax position, and need for RRSP room. Salary bonuses generate RRSP contribution room and are deductible to the corporation, but trigger CPP/EI. Dividends don't create RRSP room but may result in lower overall tax if your corporation benefits from the small business deduction. Our Mississauga CPA firm specializes in salary-dividend optimization for Ontario business owners using patent-pending AI governance frameworks to model tax scenarios in real time.
Can I reduce tax on my bonus by contributing to my RRSP in Ontario?
Absolutely. RRSP contributions reduce your taxable income, so contributing part or all of your bonus to an RRSP can lower your tax bill. You can claim the deduction on your tax return even if withholding has already been applied. For high earners in the GTA, strategic RRSP timing around bonus payments can generate significant tax savings.
