How Canadian Income Tax Works

Canadian income tax operates on a progressive system, which means you don't pay the same rate on all your income. Instead, your income is divided into brackets, and each portion is taxed at its own rate. This surprises people who think earning more puts their entire income in a higher tax bracket - it doesn't.

You pay federal tax to the Canada Revenue Agency (CRA) and provincial tax to your province. Each has separate brackets and rates. For example, you might pay 15% federal tax on your first chunk of income, but your provincial rate could be anywhere from 4% to 20% depending on where you live and how much you earn.

Everyone gets a basic personal amount tax-free. For 2026, that's $15,705 federally, meaning your first $15,705 isn't taxed by the federal government. Each province has its own basic amount too. These tax-free thresholds ensure low-income earners pay little to no tax.

Understanding Deductions and Credits

This is where things get interesting. RRSP contributions are deducted from your taxable income before tax is calculated. So if you earn $80,000 and contribute $10,000 to your RRSP, you're only taxed on $70,000. That's powerful, especially in higher tax brackets.

Tax credits work differently - they're applied after your tax is calculated. Some credits are refundable (you can get money back even if you owe no tax), while others are non-refundable (they can only reduce tax owing to zero). The basic personal amount is a non-refundable credit that everyone gets.

Common deductions include union dues, childcare expenses, moving expenses for work, and employment expenses if you work from home. Keep your receipts and declaration forms - CRA can audit going back several years.

CPP and EI Explained

Canada Pension Plan (CPP) contributions are mandatory for most working Canadians. In 2026, you pay 5.95% on earnings between $3,500 and $68,500, maxing out around $3,867 annually. Your employer matches this dollar-for-dollar. If you're self-employed, you pay both portions - the full 11.9%.

Employment Insurance (EI) premiums are 1.66% on earnings up to $63,200, maxing out at about $1,049. Again, employers match your contribution. EI provides income support if you lose your job, take parental leave, or need to care for a seriously ill family member.

These aren't technically taxes, but they come off your paycheque the same way. Once you hit the maximum earnings threshold, your take-home pay increases for the rest of the year since you stop contributing.

Provincial Differences Matter

Where you live on December 31st determines your provincial tax rate for the entire year. Provincial rates vary dramatically. Alberta has a flat tax structure with low rates, while Quebec and some Atlantic provinces have higher marginal rates.

Provincial tax isn't just about rates - each province has different credits and programs. Quebec residents can claim childcare expenses at the provincial level. Ontario has different credits for seniors than BC does. Some provinces offer tax credits for transit passes, donations to local charities, or investments in small businesses.

If you move between provinces mid-year, your tax return gets complicated. You'll file as a resident of your December 31st province but might need to calculate partial-year amounts. Professional help is worth it in those situations.

Tax Planning Strategies

• RRSP Timing: Contribute in years when you're in a higher bracket for maximum savings
• Income Splitting: Pension income splitting with a spouse can reduce combined tax bills
• TFSA for Tax-Free Growth: Use TFSAs for investments you'll withdraw in retirement
• Donation Timing: Combine multiple years of donations in one year to maximize credits
• Capital Gains: Only 50% of investment gains are taxable - better than interest income
• Medical Expenses: Claim for any 12-month period ending in the tax year
• First-Time Home Buyer Credit: Worth $750 if you haven't owned in the past 4 years
