Understanding your Ontario income tax rate for 2025 is essential for accurate tax planning — whether you’re an employee, self-employed professional, or incorporated business owner in Mississauga. Ontario uses a progressive tax system where higher income is taxed at higher rates. This guide covers the complete 2025 Ontario and federal combined tax brackets, corporate tax rates, and the key thresholds that affect tax planning decisions. Pathak Professional Corporation provides personalized tax rate analysis for Mississauga residents and businesses. Call 437-872-7399.
2025 Ontario Personal Income Tax Brackets (Combined Federal + Provincial)
Ontario residents pay BOTH federal income tax AND Ontario provincial income tax on the same taxable income. The combined marginal rate is what matters most for planning:
| 2025 Taxable Income | Federal Rate | Ontario Rate | Combined Marginal Rate | Type |
|---|---|---|---|---|
| $0 – $57,375 | 15% | 5.05% | 20.05% | Lowest bracket |
| $57,375 – $114,750 | 20.5% | 9.15% | 29.65% | Second federal bracket |
| $114,750 – $150,000 | 26% | 11.16% | 37.16% | Ontario surtax begins |
| $150,000 – $220,000 | 29% | 12.16% | 43.41% | High income |
| Over $220,000 | 33% | 13.16% | 53.53% | Highest bracket (federal + Ontario surtax) |
Note on Ontario surtax: Ontario applies a surtax on top of basic Ontario tax. The surtax of 20% applies when basic Ontario tax exceeds $5,315, and an additional 36% surtax applies when basic Ontario tax exceeds $6,802. This is why the effective Ontario rate increases at higher income levels. The combined federal + provincial rates above reflect the surtax impact.

Key Ontario Income Tax Thresholds for 2025

Ontario Corporate Tax Rates 2025
Ontario corporations pay corporate income tax at different rates depending on the type and amount of income:
| Type of Corporate Income | Federal Rate | Ontario Rate | Combined Rate |
|---|---|---|---|
| CCPC — Active business income (SBD eligible, first $500K) | 9% | 3.2% | 12.2% |
| CCPC — Active business income (over SBD threshold) | 15% | 11.5% | 26.5% |
| CCPC — Investment income (RDTOH basis) | 38.67% | 11.5% | 50.17% |
| Non-CCPC general rate corporations | 15% | 11.5% | 26.5% |
| Manufacturing and processing (M&P) deduction (Ontario) | – | –2% (M&P credit) | 24.5% |
| Capital gains (50% inclusion rate in 2024) | 15% × 50% = 7.5% | 11.5% × 50% = 5.75% | 26.5% × 50% inclusion = 13.25% |
Capital gains inclusion rate alert: The 2024 federal Budget proposed increasing the capital gains inclusion rate to 2/3 for gains over $250,000 (individuals) and for all corporate capital gains. However, the legislation to increase the rate was withdrawn in early 2025. As of 2025, the inclusion rate remains 1/2 (50%) for individuals and corporations pending further legislative developments.

The Tax Deferral Advantage of Incorporating in Ontario
The most powerful implication of Ontario’s tax rate structure is the corporate tax deferral advantage. Compare:
- Unincorporated (self-employed): $200,000 in business income taxed at 46.41% marginal rate (combined federal + Ontario) = $92,820 in immediate personal tax
- Incorporated CCPC: $200,000 in corporate income taxed at 12.2% = $24,400 in corporate tax. Remaining $175,600 stays inside the corporation. The DEFERRAL = $92,820 − $24,400 = $68,420 retained inside the corporation in that year alone
This $68,420 grows inside the corporation at the low corporate tax rate. Over 20 years, this deferral advantage compounds significantly — it is the fundamental reason why incorporating makes sense for Mississauga professionals and business owners earning consistently above $70,000-$80,000 in business income. Our incorporation guide and Small Business Deduction guide explain the full analysis. Call 437-872-7399.
Ontario Tax Rate Planning Thresholds — Key Decision Points
- $57,375 threshold: Where the second federal bracket begins (20.5% federal). Income just above this level costs an extra 5.5% federal + 4.1% Ontario = 9.6% more in tax. RRSP contributions, employment deductions, or business losses that keep income just below this threshold can save significant tax
- $100,000 income level: The Ontario surtax begins to bite hard in this range. Many tax planning strategies (RRSP, pension, income splitting) target keeping taxable income below $100,000 to avoid the surtax
- $150,000 threshold: Where the 43.41% combined rate applies. At this level, every additional dollar of income costs almost 44 cents in tax. RRSP contributions, corporate structures, and income splitting are all urgently needed
- $220,000+ threshold: Where the 53.53% combined rate (federal top bracket + Ontario surtax) begins. More than half of every additional dollar goes to tax — corporate structures and family trusts become essential

Frequently Asked Questions
What is the Ontario income tax rate for someone earning $100,000 in 2025?
A Mississauga resident with $100,000 in taxable income in 2025 pays tax at multiple marginal rates (because of the progressive bracket system), but the AVERAGE (effective) rate is approximately 27-28%. The calculation: the first $57,375 is taxed at 20.05% (combined federal + Ontario); the amount from $57,375 to $100,000 is taxed at 29.65% (second bracket); this gives a blended average rate of roughly 23.5% on the full $100,000. However, non-refundable credits (basic personal amount, CPP/EI credits, etc.) reduce the tax payable below this calculation. Pathak Professional Corporation calculates precise effective tax rates for all Mississauga clients as part of annual tax planning. Call 437-872-7399.
Are capital gains taxed at a lower rate than employment income in Ontario?
Yes — capital gains have historically been taxed at a lower effective rate than employment income because only 50% of capital gains are included in taxable income (the “inclusion rate”). This means a $100,000 capital gain only adds $50,000 to taxable income — the other $50,000 is tax-free. At a 46% marginal rate, the effective rate on a $100,000 capital gain is 23% (46% × 50% inclusion). Compare this to employment income at the same level which is 100% included and taxed at 46%. NOTE: the federal government proposed increasing the inclusion rate to 66.67% for corporations and for individual gains over $250,000. This proposal was introduced in the 2024 budget but was subsequently withdrawn in early 2025. As of 2025, the 50% inclusion rate remains in force. Pathak Professional Corporation tracks capital gains tax changes for all clients with significant investment assets. Call 437-872-7399.
How can I reduce my Ontario income tax rate legally?
The most effective legal strategies for Ontario taxpayers to reduce their effective income tax rate include: (1) RRSP contributions — each dollar contributed reduces taxable income by $1 at your marginal rate; at 46%, a $20,000 RRSP contribution saves $9,200 in combined federal + Ontario tax; (2) Incorporation — shifting business income from personal (46%+) to corporate (12.2%) provides immediate tax deferral; (3) Income splitting — pension income splitting after 65, Spousal RRSP withdrawals, dividends to family members via private corporation (subject to TOSI rules); (4) TFSA contributions — investment income inside a TFSA is 100% tax-free forever; (5) Charitable donations — federal and Ontario donation credits reduce tax at the highest marginal rate for large donations; (6) Tax loss harvesting — selling investments at a loss to offset capital gains in the same or prior three years. Pathak Professional Corporation builds personalized tax reduction strategies for Mississauga clients. Call 437-872-7399.
What is the Ontario provincial income tax rate on dividends in 2025?
Dividend income from Canadian corporations is taxed differently than other income types because of the dividend tax credit system. In Ontario in 2025: eligible dividends (from large/public corporations) are grossed up by 38% and then receive a federal and Ontario dividend tax credit — the effective combined rate on eligible dividends is approximately 39.34% at the top bracket (well below the 53.53% rate on salary). Non-eligible dividends (from CCPCs) are grossed up by 15% and receive a smaller dividend tax credit — the effective combined rate on non-eligible dividends is approximately 47.74% at the top bracket. Small business owners choosing between salary and dividends from their CCPC must carefully compare the after-tax outcome at their specific income level, accounting for CPP contributions on salary (which are also a cost but provide CPP benefit), EHT, and RRSP room. Pathak Professional Corporation models the optimal salary vs dividend mix for each incorporated Mississauga client. Call 437-872-7399.
