How federal income tax is calculated
Federal income tax applies to your net income after deductions like RRSP contributions, union dues, and employment expenses. The 2025 federal brackets are: 15% on the first $57,375, 20.5% on $57,376–$114,750, 26% on $114,751–$177,882, 29% on $177,883–$253,414, and 33% on income above that. The Basic Personal Amount ($16,129 for 2025) converts to a 15% non-refundable credit, effectively making the first $16,129 of income tax-free.
CPP and EI contributions
- CPP1: 5.95% of earnings between the Year's Basic Exemption ($3,500) and YMPE ($71,300)
- CPP2 (enhanced): 4% on earnings between $71,300 and the Year's Additional Maximum Pensionable Earnings ($81,900)
- EI premium: 1.64% of insurable earnings up to $63,200 in 2025
- Employer matches CPP at 1:1 and EI at 1.4× the employee premium
- Quebec residents pay QPP (instead of CPP) and QPIP (instead of federal EI)
How to use the Canadian income tax calculator
- Enter your gross annual employment income
- Select your province or territory
- Enter RRSP contribution amount to reduce taxable income
- Review federal tax, provincial tax, CPP, EI, and net income
- Switch tax years (2024 or 2025) to compare year-over-year changes
💡 RRSP contributions reduce both federal and provincial tax
RRSP contributions reduce your net income before both federal and provincial tax are applied. For an Ontario resident in the 33% federal bracket, a $10,000 RRSP contribution could save over $4,000 in combined taxes — among the most efficient tax strategies available to Canadians.
Common mistakes to avoid
- Forgetting that provincial tax is calculated separately — it's not a simple add-on percentage to federal tax
- Not factoring in CPP2 contributions for higher earners — introduced in 2024, they're often overlooked
- Ignoring the RRSP deadline (March 1) — contributions made after the deadline count for the next tax year
- Not claiming all non-refundable credits (age amount, disability, caregiver) that reduce both federal and provincial tax
- Using a US-style calculation approach — Canada has different credit structures and fewer standard deductions
