Canadian income tax is calculated in layers: federal tax first, then provincial tax, then payroll deductions (CPP and EI), minus various credits. Each layer has its own rates and thresholds. This guide walks through each one so you understand exactly what you're paying and why.
The Big Picture: What Makes Up Your Total Tax
For most employed Canadians, your total deductions from a paycheque include:
- Federal income tax — graduated brackets, 15% to 33%
- Provincial income tax — separate brackets for your province
- CPP contributions — pension contributions, shared with your employer
- EI premiums — employment insurance premiums
Credits (Basic Personal Amount, CPP/EI credits, etc.) then reduce steps 1 and 2. The net result is what you actually owe.
Step 1: Calculate Total Income
Add up all income sources
Canadian tax applies to your worldwide income from all sources:
- Employment income (T4 box 14)
- Self-employment net income
- Investment income: interest, dividends, rental income
- Capital gains (at the applicable inclusion rate)
- RRSP withdrawals, RRIF payments, pension income
- OAS and CPP/QPP payments
- Employment Insurance benefits
TFSA withdrawals, GST/HST credits, and CCB payments are not included in income.
Step 2: Calculate Net Income
Subtract above-the-line deductions
Certain deductions reduce your total income before credits are applied. The most common:
- RRSP contributions — the biggest one for most Canadians
- Union dues and professional membership fees
- Childcare expenses
- Moving expenses
- Employment expenses (with T2200)
- Business expenses (self-employed)
- Capital losses (to offset capital gains)
Total Income − Deductions = Net Income
Net income determines your eligibility for many income-tested benefits and credits (CCB, GST credit, OAS clawback threshold).
Step 3: Calculate Federal Tax
Apply the federal brackets to taxable income
Federal tax is calculated on taxable income (net income minus a few additional deductions like the basic personal amount adjustment). The 2026 federal brackets are:
| Taxable Income | Federal Rate | Tax on Bracket |
|---|---|---|
| $0 – $57,375 | 15% | Up to $8,606 |
| $57,375 – $114,750 | 20.5% | Up to $11,762 |
| $114,750 – $158,519 | 26% | Up to $11,380 |
| $158,519 – $220,000 | 29% | Up to $17,830 |
| Over $220,000 | 33% | — |
These are marginal rates — each bracket only applies to the income within that range. A person earning $80,000 does NOT pay 20.5% on all $80,000. They pay 15% on the first $57,375, and 20.5% on the remaining $22,625.
Example: Federal tax on $80,000
Next $22,625 × 20.5% = $4,638
Gross federal tax = $13,244
Step 4: Apply Federal Non-Refundable Credits
Subtract credits from gross federal tax
Credits are applied at 15% of the credit amount (the lowest federal bracket rate). Every Canadian automatically receives at minimum:
- Basic Personal Amount (BPA): $16,129 × 15% = $2,419 credit
- CPP Employee Credit: CPP paid × 15%
- EI Premium Credit: EI paid × 15%
Continuing the $80,000 example (with CPP of $3,867 and EI of $1,049):
Less BPA credit: − $2,419
Less CPP credit: − $580
Less EI credit: − $157
Net federal tax = $10,088
Step 5: Calculate Provincial Tax
Apply provincial brackets and provincial BPA credit
Each province has its own set of tax brackets — entirely separate from the federal calculation. Provincial rates range from Ontario's 5.05% starting rate to Quebec's 14% top rate. Each province also has its own Basic Personal Amount.
Example: Ontario provincial tax on $80,000
Ontario 2026 brackets:
| Income Range | Ontario Rate |
|---|---|
| $0 – $51,446 | 5.05% |
| $51,446 – $102,894 | 9.15% |
| $102,894 – $150,000 | 11.16% |
| $150,000 – $220,000 | 12.16% |
| Over $220,000 | 13.16% |
Next $28,554 × 9.15% = $2,613
Gross Ontario tax: $5,211
Less Ontario BPA credit: − $561 (approx)
Less CPP/EI credits: − $110 (approx)
Net Ontario tax ≈ $4,540
Note: Ontario also has a health premium (up to $900/year for incomes over $20,000) which is collected as part of provincial tax. Some provinces also have surtaxes or low-income reductions that adjust the result further.
Step 6: Calculate CPP Contributions
CPP1 and CPP2 (new in 2019/2024)
The Canada Pension Plan has two tiers in 2026:
| Tier | Rate (Employee) | Income Range | Max Contribution |
|---|---|---|---|
| CPP1 | 5.95% | $3,500 – $68,500 | $3,867 |
| CPP2 | 4.00% | $68,500 – $73,200 | $188 |
Your employer matches your CPP1 and CPP2 contributions. Self-employed individuals pay both the employee and employer share (11.9% for CPP1).
For our $80,000 example:
CPP2: ($73,200 − $68,500) × 4.00% = $188
Total CPP employee = $4,056
Step 7: Calculate EI Premiums
Employment Insurance premiums
EI premiums in 2026 are 1.66% of insurable earnings, up to a maximum insurable amount of $63,200.
EI = $63,200 × 1.66%
EI premium = $1,049
Quebec residents pay a lower EI rate (approx 1.31%) because Quebec has its own parental insurance plan (QPIP). Employers pay 1.4× the employee EI rate.
Step 8: Add It All Up
Total deductions from $80,000 employment income (Ontario)
Ontario income tax: $4,540
CPP contributions: $4,056
EI premiums: $1,049
Total deductions: $19,733
Less total deductions: − $19,733
After-tax take-home ≈ $60,267
That's an effective total tax rate of about 24.7%, or a marginal rate of ~43.4% on the last dollar earned.
Understanding Marginal vs. Effective Rate
These are the two most important percentages to understand:
- Marginal rate — the tax rate you pay on your next dollar of income. This is what matters for decisions like "should I contribute to my RRSP?" (you save at your marginal rate) or "should I take on more work?" At $80,000 in Ontario, your marginal rate is roughly 43.4% (20.5% federal + 9.15% Ontario + 5.95% CPP).
- Effective rate — total tax divided by total income. For our $80,000 earner in Ontario, it's $14,628 ÷ $80,000 = ~18.3% for income tax only (excluding CPP and EI).
The progressive nature of the system means your effective rate is always much lower than your marginal rate.
How RRSP Contributions Change the Calculation
If our $80,000 Ontario earner contributes $10,000 to an RRSP:
- Taxable income drops from $80,000 to $70,000
- $10,000 that was taxed at the 20.5% federal bracket + 9.15% Ontario bracket = 29.65% combined
- Tax saving: approximately $2,965 just on federal + Ontario income tax
- The investment grows tax-sheltered until withdrawal

Quebec: A Different System
Quebec residents file two separate tax returns: the federal T1 (with a 16.5% federal tax abatement that reduces federal tax) and the provincial TP-1 return filed with Revenu Québec. Quebec also administers QPP (instead of CPP) and has its own QPIP parental benefits plan. The net tax burden in Quebec is high due to the province's extensive public services, but the federal abatement partially offsets this.
