Calculate Your Taxes
Understanding Canada's Tax System
Canada uses a progressive tax system where both federal and provincial tax apply to the same income. Here are the key concepts:
Basic Personal Amount (BPA)
Both federal and provincial governments give you a personal amount that is not taxed. For 2026, the federal BPA is approximately $15,705, and provincial BPAs range from $11,865 (Ontario) to $21,003 (Alberta). These reduce your taxable income dollar-for-dollar.
Combined Tax Brackets
Your marginal tax rate (the rate on your next dollar of income) is the sum of federal and provincial rates. In high-income provinces, combined marginal rates can exceed 50%. For example, in British Columbia at $350,000 income, the combined rate is approximately 56.2%.
CPP and EI Contributions
In addition to income tax, employees contribute to the Canada Pension Plan (CPP) at 5.95% on earnings between $3,500 and $68,500, plus an additional top-up contribution (CPP2). Employment Insurance (EI) is deducted at 1.66% on insurable earnings up to the annual maximum.
Canadian Example (2026)
Federal tax: ~$13,600 (after basic personal amount of $15,705)
Ontario provincial tax: ~$5,800 (after provincial BPA of $11,865)
CPP contribution: ~$3,867
EI premium: ~$1,049
Net take-home: ~$60,684/yr (~$5,057/mo)
Effective tax rate: ~28.6%
Marginal tax rate: ~43.4% (combined federal + provincial)
What Your Results Mean
Effective Tax Rate vs Marginal Tax Rate
Effective tax rate is all your taxes divided by your gross incomeβit's what you actually pay as a percentage. Marginal tax rate is the tax rate on your next dollar earned. The marginal rate is always higher because Canada's system is progressive. Understanding this matters for decisions about RRSP contributions or side income.
Monthly vs Bi-Weekly Paycheques
Your net annual income divided by 12 gives your monthly take-home. Most Canadian employers run payroll bi-weekly (26 pay periods per year), so divide by 26 for your typical paycheque amount. Tax deductions and CPP/EI contributions are usually deducted from each paycheque.
RRSP Contributions Reduce Taxable Income
Any amount you contribute to a Registered Retirement Savings Plan (RRSP) reduces your taxable income. This means if you earn $85,000 and contribute $10,000 to an RRSP, you pay tax on only $75,000. At a 43.4% marginal rate, that saves you $4,340 in taxes. This "tax refund" is a powerful reason to max out your RRSP room.
Frequently Asked Questions
What is the difference between marginal and effective tax rate?
Marginal tax rate is the tax on your next dollar earned. In Ontario at $85,000 income, the marginal rate is 43.4% (15% federal + 9.15% provincial). If you earn one more dollar, you keep approximately 56.6Β’ after tax.
Marginal rate is more relevant for decisions about additional income (bonuses, freelance work, RRSP contributions) because it shows what you actually keep.
How do RRSP contributions reduce my taxes?
Which province has the highest income taxes in Canada?
However, at mid-range incomes ($100,000), the differences are smaller. For high earners, provincial choice matters significantly for tax planning.
What is the basic personal amount for 2026?
Provincial BPAs vary:
β’ Alberta: $21,003 (highest)
β’ Ontario: $11,865
β’ British Columbia: $11,981
β’ Quebec: $17,183
β’ Newfoundland & Labrador: $10,820 (lowest)
Higher BPAs mean less tax for low-income earners. The BPA essentially creates a tax-free threshold: the first $15,705 (federal) + your provincial amount of income is not taxed.
How are CPP and EI calculated?
EI (Employment Insurance): Employees contribute 1.66% of insurable earnings up to the annual maximum (approximately $63,200 in 2024). The employer pays a matching premium (1.66% Γ 1.6 = 2.66% in most provinces).
Both are deducted from paycheques automatically and are not optional.
Do I owe taxes if my employer already deducts them?
β’ You have multiple jobs (incorrect total deductions)
β’ You earned capital gains or investment income
β’ You have business income or rental income
β’ You claimed too many exemptions
Conversely, you may be owed a refund if:
β’ You contributed to an RRSP (reduces taxable income)
β’ You qualify for tax credits (medical expenses, donations, tuition)
β’ Your employer over-withheld
Always file your annual tax return with the CRA (Canada Revenue Agency) to settle your exact tax liability.
Tax Tips to Maximise Your Take-Home
If you're in a high tax bracket (above 40%), prioritise RRSP contributions over TFSA. The immediate tax refund is substantial and can be reinvested.
Don't miss deductions for union dues, professional fees, moving expenses, or home office setup costs. Keep receipts and file them with your tax return.
If you earn significantly more than your spouse, contribute to a spousal RRSP. Both get the same tax deduction, but the lower-income spouse withdraws at retirement and pays less tax.
Only 50% of capital gains are taxable (dividends vary by type). Employment income is fully taxable, making capital gains more tax-efficient for investing.
