Bonus Tax in Ontario: How It Works
Ontario has the largest population and most complex tax structure of any Canadian province, with five tax brackets plus two surtaxes that apply at higher income levels. The combined federal-Ontario top marginal rate reaches approximately 53.5%. For Toronto, Ottawa, Hamilton, and Mississauga residents, bonuses are a common form of compensation and the bonus method is well understood by payroll teams.
Ontario's 2026 provincial brackets are 5.05% (up to $51,446), 9.15% ($51,446–$102,894), 11.16% ($102,894–$150,000), 12.16% ($150,000–$220,000), and 13.16% above $220,000. The Ontario surtax adds 20% on Ontario tax over $5,710 and an additional 36% on Ontario tax over $7,307, effectively raising the top combined provincial rate above 20%. For an Ontario resident earning $90,000 receiving a $10,000 bonus, expect roughly 33–37% withheld for combined income tax plus CPP and EI.

Ontario Bonus Tax: Specific Considerations
Ontario's surtax structure is the country's most complex for bonus calculations. A $5,000 bonus on $80K in Toronto, Mississauga, or Ottawa is taxed at 20.5% federal + 9.15% ON + Ontario Health Premium impact = roughly 30.5% effective, netting about $3,475. A $10,000 bonus on $80K nets approximately $6,950. At $25K bonus on $80K, parts cross the $102,894 Ontario bracket and trigger the 20% Ontario surtax (on tax > $5,710), producing effective withholding around 35–38% and net bonus near $15,500–$16,000. The Ontario surtax adds 20% on Ontario tax over $5,710 and a further 36% on Ontario tax over $7,307 — meaning a $25K bonus to a $150K Toronto bank executive can face effective combined rates above 47%.
Toronto-area earners should pay particular attention to the Ontario surtax trigger points: roughly $87,000 income (for the 20% surtax) and $107,000 (for the additional 36% surtax). A bonus that pushes you across these thresholds adds disproportionately to tax owing. The Ontario Health Premium ($300–$900/year) is built into the regular Ontario tax tables, not a separate withholding. Bay Street financial professionals receiving large performance bonuses should consider RRSP top-ups via T1213 (Request to Reduce Tax Deductions at Source) — this can lower withholding by thousands on a six-figure bonus.
Bonus Tax Planning in Ontario
Ontario residents have many tools to manage bonus tax: RRSP contributions (with potential to reduce withholding at source via T1213), Group RRSP enrollment, and Ontario-specific credits like the Ontario Trillium Benefit and Ontario Sales Tax Credit (which affect filing-time refunds, not bonus withholding). The Ontario Health Premium is included in regular income tax brackets and does not add separately to bonus tax.
The CRA bonus method approximates your marginal tax rate by calculating tax on (annual salary + bonus) and subtracting tax on the salary alone. For Ontario residents, this means the withholding closely tracks your true marginal rate — usually within a few percentage points. If you receive your bonus near the end of the year and have already maxed out CPP and EI contributions, your effective withholding rate may be noticeably lower than mid-year bonuses for the same gross amount. RRSP contributions, FHSA contributions, and (in some cases) charitable donations can reduce tax withheld at source if you file CRA Form T1213 (Request to Reduce Tax Deductions at Source) in advance.
