Canada’s income tax system is two-tiered: you pay federal tax to the CRA, plus provincial or territorial tax to your home province. Both are calculated on the same taxable income, but use different rates and bracket thresholds. The combined marginal rate—what you pay on the next dollar of income—varies widely by province.
Federal + Provincial: How They Stack
Federal and provincial taxes are calculated separately and then added together. A high-income earner in Quebec faces a top combined marginal rate above 53%; the same earner in Alberta pays around 48%.
2025 Federal Income Tax Rates:
| Federal Taxable Income | Federal Rate |
|---|---|
| Up to $57,375 | 15% |
| $57,376 – $114,750 | 20.5% |
| $114,751 – $158,519 | 26% |
| $158,520 – $220,000 | 29% |
| Over $220,000 | 33% |
The Basic Personal Amount (federal) is $16,129 for 2025—the first $16,129 of income is tax-free federally.

Quebec: A Different System
Quebec operates a largely separate tax administration—you file two returns: one with the CRA (T1) and one with Revenu Québec ( provincial). Key differences:
- Quebec abatement: Federal tax is reduced by 16.5% for Quebec residents to account for Quebec administering its own programs
- Quebec residents receive the full abatement but pay significant provincial tax instead
- Quebec has its own equivalent of many federal credits, often with different thresholds
- QPIP (Quebec Parental Insurance Plan) replaces federal EI for parental benefits
Key Provincial Tax Credits
Most provinces offer credits equivalent to federal ones, but with province-specific amounts. Key credits to claim:
| Credit | Federal | Ontario Example | BC Example |
|---|---|---|---|
| Basic Personal Amount | $16,129 | $11,865 | $11,981 |
| Age Amount (65+) | $8,396 | $5,897 | $4,975 |
| Disability Amount | $9,872 | $9,586 | $9,428 |
| Charitable donations (first $200) | 15% | 5.05% | 5.06% |
| Charitable donations (above $200) | 29–33% | 11.16% | 16.8% |
Provincial credits are non-refundable unless specified, meaning they reduce tax owing but cannot create a refund on their own.
Provincial Dividend Tax Credits
Dividends from Canadian corporations receive gross-up treatment and a dividend tax credit (DTC) at both federal and provincial levels. The combination of gross-up and DTC means eligible dividends (from publicly traded companies) are taxed favourably—effective rate around 25–39% at top brackets depending on province.
| Province | Eligible DTC Rate | Non-Eligible DTC Rate |
|---|---|---|
| Ontario | 10% | 4.5% |
| BC | 12% | 1.96% |
| Alberta | 10% | 3.01% |
| Quebec | 11.9% | 6.28% |
| Saskatchewan | 11% | 3.33% |
The provincial DTC stacks with the federal DTC—both reduce the effective tax rate on dividends.
Decision Framework: Province and Tax Planning
| Situation | Key Tax Consideration |
|---|---|
| High-income and mobile profession | Alberta offers lowest combined rates above $100K; no PST |
| Significant investment income | Province of residence on December 31 determines which provincial rates apply |
| Filing in Quebec | File both T1 and Quebec return; different credits and amounts |
| Age 65+, lower income | Age amount credits at both federal and provincial level; RRSP withdrawals affect GIS |
| Small business income | Provincial small business rate (SBD) reduces provincial corporate tax on first $500K |
| Large charitable gift | Donate in high-income year for top marginal credit rate |
Provincial Small Business Tax Rates
Each province offers a reduced corporate tax rate on the first $500,000 of active business income (the Small Business Deduction). Combined with the federal small business rate of 9%, total corporate rates for qualifying income are substantially lower than personal rates:
| Province | Provincial SBD Rate | Combined Fed + Prov Rate |
|---|---|---|
| Alberta | 2% | 11% |
| Ontario | 3.2% | 12.2% |
| BC | 2% | 11% |
| Quebec | 3.2% | 12.2% |
| Saskatchewan | 1% | 10% |
| Manitoba | 0% (SBD eliminated 2020) | 9% (federal only on first $500K) |
This creates a significant incentive to incorporate a small business drawing profits below $500,000—the after-tax corporate income can be used to fund a holding company, invest inside the corporation, or be distributed as a dividend (triggering personal tax at dividend rates when taken out).
Provincial Income Tax and Retirement Planning
For retirees, provincial tax intersects with federal benefits in important ways:
- BC Seniors Supplement / Ontario GAINS: Low-income seniors may receive provincial top-up payments
- Age Amount (provincial): Each province sets its own age amount credit for seniors 65+, reducing provincial tax
- Pension Income Splitting: The federal pension splitting election (up to 50% of eligible pension income transferred to spouse) reduces combined federal + provincial tax at both levels simultaneously
- OAS Clawback: Uses net income before the GIS/OAS clawback threshold—RRSP withdrawals and RRIF income both count; TFSA withdrawals do not
Frequently Asked Questions
Which province has the lowest income tax? For incomes above $100,000, Alberta typically has the lowest combined federal + provincial rate. For lower incomes, the picture varies—Nunavut has the lowest bottom rate (4%), and several small provinces have lower rates in the first bracket.
If I move provinces during the year, which provincial tax applies? You pay the tax rate for the province where you are resident on December 31 of the tax year. If you moved from Ontario to Alberta on October 1, you file as an Alberta resident for the full year. However, income earned in each province is accounted for.
Do I have to file separately with Quebec? Yes. Quebec residents file a federal T1 return with the CRA and a separate provincial TP-1 return with Revenu Québec. The CRA administers most other provincial returns—Quebec is the exception.
What is the Ontario Surtax? Ontario charges a surtax on top of provincial income tax if your basic Ontario tax exceeds $5,831—adding 20%—and a second surtax of 36% on Ontario tax exceeding $7,459. This means higher-income Ontario residents effectively pay more than the headline 13.16% top rate suggests.
Are provincial tax credits different from federal ones? Yes. Each province sets its own credit amounts, phase-out thresholds, and available credits. Some provinces offer credits that don’t exist federally—for example, BC’s renter’s tax credit or Ontario’s LIFT credit for low-income workers.
Does RRSP contribution reduce provincial tax too? Yes. RRSP contributions reduce your net income (line 23600), which is the base for both federal and provincial tax calculations. So a $10,000 RRSP contribution saves tax at your combined (federal + provincial) marginal rate.
