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 $53,891), 9.15% ($53,891–$107,785), 11.16% ($107,785–$150,000), 12.16% ($150,000–$220,000), and 13.16% above $220,000. The Ontario surtax adds 20% on Ontario tax over $5,818 and an additional 36% on Ontario tax over $7,446, effectively raising the top combined provincial rate above 20%. For an Ontario resident earning $90,000 receiving a $10,000 bonus, expect about 30% withheld (29.9%) — all of it income tax, since CPP and EI are already maxed out at $90,000, including about $26 of surtax on the part of the bonus above a salary of roughly $98,600.

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 = 29.65% (the Ontario Health Premium is already at its $750 plateau at this income, so it adds nothing); the last $200 of CPP2 is deductible, so income tax is $1,423 and the bonus nets about $3,577 after income tax — $3,377 once that CPP2 comes off. A $10,000 bonus on $80K nets approximately $7,094 after income tax. At $25K bonus on $80K, income reaches $105K and stays inside the 9.15% Ontario bracket, but the top of the bonus passes the point where the 20% Ontario surtax begins (basic Ontario tax above $5,818, reached at a salary of about $98,600), which adds about $117 — so the bonus method withholds about 30.7% and nets roughly $17,330. The surtax adds 20% on basic Ontario tax over $5,818 and a further 36% over $7,446 — meaning a $25K bonus to a $150K Toronto bank executive is taxed at about 45%, $1,696 of it surtax.
Toronto-area earners should pay particular attention to the Ontario surtax trigger points: a salary of roughly $98,600 (for the 20% surtax) and $115,000 (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 withheld along with Ontario tax and is flat across most incomes (it tops out at $900), so it only adds to bonus tax when a bonus crosses one of its short phase-in steps.
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.
Bonus Tax in Ontario — FAQ
How much tax is withheld on a $5,000 bonus in Ontario?
On a $75,000 salary, a $5,000 bonus in Ontario has about $1,623.20 withheld — $984.00 federal, $439.20 provincial, $200.00 CPP and $0.00 EI — leaving $3,376.80 net, an effective rate of 32.46%. Your own figure moves with your salary, because the CRA bonus method taxes the bonus at the marginal rate that your salary already puts you in.
Is a bonus taxed at a higher rate than salary in Ontario?
No. A bonus is ordinary employment income and is taxed at exactly the same rates as salary. It only feels higher because payroll uses the CRA bonus method: tax is computed on (annual salary + bonus), then tax on the salary alone is subtracted, so the whole bonus is withheld at your top marginal rate instead of your average rate. Any over-withholding comes back as a refund when you file.
What are the Ontario provincial tax brackets for 2026?
Ontario applies 5.05% on $0.00–$53,891.00, 9.15% on $53,891.00–$107,785.00, 11.16% on $107,785.00–$150,000.00, 12.16% on $150,000.00–$220,000.00, 13.16% above $220,000.00. The top provincial rate of 13.16% starts at $220,000.00 of taxable income, and a bonus that carries you across a bracket line is taxed at the higher rate only on the portion above it.
Does maxing out CPP and EI change my bonus withholding in Ontario?
Yes, and it can be worth hundreds of dollars. For 2026 the CPP maximum is $4,230.45 plus $416.00 of CPP2, and the EI maximum is $1,123.07. Once you have hit those ceilings for the year, no further CPP or EI comes off — so an identical bonus paid in November nets more than one paid in February.
How can I reduce the tax withheld on a bonus in Ontario?
The two practical levers are an RRSP contribution made directly by your employer out of the bonus (no tax is withheld on the amount transferred), and CRA Form T1213, Request to Reduce Tax Deductions at Source, filed in advance. Both reduce withholding at source rather than waiting for a refund at filing time.
Where does Ontario rank for keeping the most of a bonus?
On the $75,000 + $5,000 scenario, Ontario ranks 4 of 13, netting $3,376.80. British Columbia tops the table at $3,446.40, $69.60 more than Ontario on the identical bonus.
