Your Tax Breakdown
How Your Income Is Taxed, Bracket by Bracket
Each bracket applies only to the income that falls within its range. No income is retroactively taxed at a higher rate when you cross a threshold.
Your Marginal Rate vs Your Effective Rate
Your marginal rate is the rate on the next dollar you earn. Your effective rate is the average rate across your entire income. These are always different — and confusing them is the most common tax misconception in Canada.

Ontario Tax Explained: Surtax and the Health Premium
The Ontario surtax
The Ontario surtax triggers on your basic Ontario tax — not on your income. Once your basic Ontario tax (the amount before surtax) exceeds , a 20% surtax applies to the amount above that threshold. If your basic Ontario tax exceeds , an additional 36% surtax applies to the amount above that second threshold.
At the trigger, your income is approximately $. Below that income level, the surtax does not apply at all — regardless of your bracket rate.
Surtax = 20% × max(0, basicOntarioTax − ) + 36% × max(0, basicOntarioTax − )
The Ontario Health Premium
The OHP is collected at tax filing time — it does not appear as a line on your paycheque. It is based on your taxable income for the year and follows a band schedule capped at . The premium applies starting at $20,000 of income and reaches its maximum above $200,600.
Federal Tax in : The Rate Cut and the Basic Personal Amount
Why the bottom rate is 14%, not 15%
The Basic Personal Amount credit
The federal BPA is not a tax-free zone. It is a non-refundable credit. The full BPA of generates a credit of ( × ). That credit is subtracted from your calculated federal tax — it does not reduce the income that enters the brackets.
For incomes above , the BPA begins to phase down. It reaches its base value of at .
Ontario has its own BPA: , generating a credit of ( × ).

Why Did My Tax Go Up? The Raise and Overtime Questions
You got a raise — only the new portion is taxed more
When your income crosses a bracket threshold, the higher rate applies only to the dollars above that threshold. Your existing income is never retroactively taxed at the new rate.
Example: Your salary increases from $58,000 to $65,000. You crossed the federal second bracket at . Only the above that threshold is taxed at 20.5% — the rest stays at 14%. Your take-home pay increases with every dollar of the raise.
Overtime pay looks over-taxed on the cheque
Payroll software calculates source deductions by annualizing each pay period. If you earn a week of overtime, the software treats it as if you earn that amount every week — inflating the projected annual income and withholding at a higher rate. At year-end, the actual rate is correct. You typically receive a refund if overtime was a one-time event.
A raise never reduces your take-home pay
No bracket crossing makes your net income decrease. The highest-bracket rate applies only to the marginal dollars. Every dollar of gross income always adds to net income — the rate increases, but never by more than 100% of the increment.
CPP and EI: Deductions That Reduce Your Tax
CPP1 and EI generate non-refundable tax credits
Your CPP1 contributions and EI premiums are deducted from your employment income before income tax is calculated. They also generate non-refundable credits at the federal and Ontario lowest bracket rates — reducing your final tax liability further.
CPP1 maxes at (on earnings up to minus the $3,500 basic exemption, at ). EI maxes at (on earnings up to , at ).
CPP2 is different: it reduces income but generates no credit
On earnings between and , you pay CPP2 at , up to . Unlike CPP1, CPP2 contributions do not generate a non-refundable tax credit — they are simply deducted from gross income. This asymmetry means CPP2's tax benefit is smaller than CPP1's per dollar contributed.
Are CPP and EI taxes?
CPP contributions build your entitlement to CPP retirement, disability, and survivor benefits. EI premiums fund your entitlement to employment insurance benefits. Neither is a pure tax — both are insurance/pension contributions with defined benefit structures. The employer matches CPP at 1:1 and EI at 1.4:1.

Three Real Tax Calculations
$60,000 — First-time filer, marketing coordinator, Toronto
At $60,000, your income crosses into the second federal bracket mid-year but stays in the first Ontario bracket. The defining feature of this income level: most of the salary is taxed at the 14% federal rate, not the 20.5% rate that applies only to the $1,477 above the first federal bracket threshold.
$110,000 — Senior professional, project manager, Ottawa
At $110,000, two things happen that don't apply at $60,000: the income enters the third federal bracket () for a portion, and the basic Ontario tax crosses the first surtax threshold, triggering the 20% Ontario surtax on that excess. The combined effect makes the effective rate jump noticeably compared to $100,000.
$185,000 — Executive, VP Operations, Mississauga
At $185,000, the federal 29% bracket applies to the portion of income — after CPP and EI — that exceeds . The Ontario surtax applies fully at both tiers. OHP reaches . The federal BPA begins its phase-down above .
Specific Tax Questions
I got a raise to $60,000 — will I take home less money?
No. The second federal bracket () applies only to the income above . If your previous salary was $58,000 and your new salary is $60,000, only the $1,477 above the bracket threshold is taxed at 20.5% instead of 14%. That incremental difference is approximately $96 more in federal tax on the full raise — not a reduction in take-home pay on the salary below $58,523. Your after-tax pay increases with every dollar of the raise.
What is the Ontario surtax and who pays it?
The Ontario surtax is an additional levy on your basic Ontario tax — not on your income. It triggers when your basic Ontario tax exceeds . At that threshold, the corresponding income is roughly $. The 20% surtax applies to the basic Ontario tax above that amount; if your basic Ontario tax also exceeds , an additional 36% applies to that higher excess. Most Ontario earners below $80,000 pay zero surtax.
Why do I pay more tax than a colleague in Quebec with the same salary?
Ontario and Quebec have different provincial tax structures. Ontario's five brackets range from 5.05% to 13.16%, but Ontario also levies a surtax and the Ontario Health Premium that Quebec does not. Quebec has higher provincial rates at lower incomes but allows deductions Ontario does not. The federal tax is identical in both provinces; the difference is entirely provincial. At $75,000, the Ontario-Quebec difference in total provincial tax is typically $1,000–$2,500 depending on credits claimed.
Is CPP a tax or a contribution?
CPP is a mandatory contribution to a defined-benefit pension plan — not a tax. Your CPP1 contributions (up to in ) accumulate entitlements that pay out as retirement income, disability benefits, and survivor benefits. The contribution rate () and ceiling () are set annually by the federal government. Unlike income tax, CPP contributions have a defined return: your CPP pension at 65 is directly related to your contribution history.
What is the Ontario Health Premium and why isn't it on my paycheque?
The OHP is an Ontario provincial levy collected through the tax return — not through payroll. It does not appear on your T4 or paycheque stub. The OHP applies based on your taxable income for the full year, ranging from $0 under $20,000 to a maximum of above $200,600. You pay it when filing your Ontario return. If you are surprised by an OHP balance owing, it is because the annual calculation was not reflected in payroll withholding.
My employer withholds tax at source — will I owe more at tax time?
Whether you owe more at tax time comes down to whether your employer's source deduction matched your actual annual income. CRA uses annualized withholding based on your regular pay period. If you had a bonus, irregular overtime, or multiple employers in the same year, the total withholding may fall short of what you actually owe — potentially by hundreds of dollars. RRSP contributions, deductible union dues, or other credits can go the other way and produce a refund. The most reliable approach: run the full calculation at your actual year-end income to check before April.

How This Calculator Works
Rates current for tax year . Last updated: .
Federal income tax
Progressive bracket application on employment income minus CPP1 and EI. Federal Basic Personal Amount credit applied at the lowest federal bracket rate. Formula: BPA × creditRate. CPP1 and EI each generate additional non-refundable credits at the same rate.
Ontario provincial tax
Progressive bracket application on the same taxable income (after CPP1 and EI). Ontario BPA credit applied at Ontario's lowest rate. Ontario surtax formula: 0.20 × max(0, basicOntarioTax − threshold1) + 0.36 × max(0, basicOntarioTax − threshold2). Surtax is applied to basic Ontario tax, not to income.
Ontario Health Premium
Computed from the OHP band schedule using gross income. Not a payroll deduction. Effective rate formula: (federalTax + ontarioTax + surtax + OHP) / grossIncome.
CPP and EI
CPP1 on (income − $3,500) × 5.95%, capped at max CPP1. CPP2 on earnings between YMPE and YAMPE at 4.00%, capped at max CPP2. CPP2 is not deductible for tax credit purposes. EI on earnings up to maximum insurable earnings at the premium rate, capped at the annual maximum.
Known limitations
This calculator estimates income tax on employment income only. It does not account for: RRSP contributions, childcare deductions, union dues, eligible/non-eligible dividends, capital gains, rental income, self-employment income, or provincial tax credits beyond the BPA and CPP/EI credits.
