Calculate Total Income
Sum all income: employment (T4), self-employment, interest, dividends (grossed-up), rental income, capital gains (50% inclusion), pensions, EI/government benefits. This is your Total Income (Line 15000).
Calculate Net Income
Subtract deductions from total income: RRSP contributions, union dues, childcare expenses, moving expenses, employment expenses, carrying charges. Result is Net Income (Line 23600), used for income-tested benefits.
Calculate Taxable Income
Subtract additional deductions from net income: capital loss carryforwards, northern residents deduction, other specific deductions. Result is Taxable Income (Line 26000), the base for tax calculation.
Apply Federal Tax Brackets
Tax calculated progressively: 14% on first $58,523; 20.5% on $58,523–$117,045; 26% on $117,045–$181,440; 29% on $181,440–$258,482; 33% above $258,482. Each portion of income taxed only at its bracket rate.
Subtract Non-Refundable Credits
Apply credits to reduce federal tax: Basic Personal Amount, Canada Employment, CPP/EI credits, age amount, pension income, disability, tuition, medical expenses, charitable donations. Credits are calculated at 15% (except donations above $200 at 29%/33%).
Add Provincial Tax
Calculate provincial tax separately using provincial brackets and rates (vary widely by province). Apply provincial non-refundable credits. Provincial tax is added to federal tax for total income tax.
Add CPP and EI Contributions
CPP: 5.95% on earnings $3,500–$74,600 plus 4% on $74,600–$85,000. EI: 1.63% on earnings up to $68,900. These are separate from income tax but deducted from each paycheque alongside tax withholding.
Calculate Final Tax and Net Pay
Total deductions = federal income tax + provincial income tax + CPP + EI. Gross pay minus total deductions = net pay (take-home). Annual return reconciles actual tax owed versus amount withheld — result is a refund or balance owing.
Example Calculation (C$75,000 annual salary, Ontario resident)
This example uses Ontario provincial rates. Actual amounts vary by province. Does not include Ontario Health Premium or surtax. RRSP contribution reduces taxable income but also reduces take-home pay. Provincial tax rates vary significantly across Canada.

CPP, EI & Payroll Contributions
Canada's social insurance system is funded through the Canada Pension Plan (CPP) and Employment Insurance (EI). CPP provides retirement, disability, and survivor pensions. EI covers unemployment, parental leave, and sickness benefits. Both are mandatory for employed and self-employed individuals (EI optional for self-employed).
02Tax Deductions and Credits
Canada offers both tax deductions (reducing taxable income) and tax credits (reducing tax owed). Non-refundable credits eliminate tax but cannot create a refund. Refundable credits can produce a refund even if no tax is owed. Federal and provincial credits often differ.
04Capital Income & Investment Taxation
Canada taxes capital gains at a 50% inclusion rate — half of the gain is added to income. Dividends receive preferential treatment through the gross-up and dividend tax credit system. Canada has no estate or inheritance tax, but deems all assets disposed at death. No wealth tax exists.
05Special Features of Canadian Tax System
Canada's tax system includes unique features: powerful registered savings plans (RRSP, TFSA, FHSA), a federal-provincial dual tax structure, generous family benefits, and a residency-based (not citizenship-based) taxation system.
06Tax Filing and Compliance
Canada operates a self-assessment system with tax withheld at source by employers. The Canada Revenue Agency (CRA) administers federal and most provincial taxes (except Quebec). Electronic filing through NETFILE is standard, and CRA My Account provides online access to tax information.
