Ontario Income Tax Calculator (Federal + Ontario)
This estimator focuses on income tax using federal and Ontario brackets, basic personal amounts, Ontario surtax, and Ontario health premium. It does not include CPP/EI payroll deductions or all tax credits.
What this Ontario tax brackets calculator does
If you live in Ontario, your income tax is built from two systems: federal tax brackets and Ontario provincial tax brackets. This calculator combines both so you can quickly estimate:
- Total annual income tax
- After-tax income
- Monthly after-tax amount
- Effective tax rate and marginal tax rate
It is designed for fast planning: job offers, RRSP contribution decisions, and understanding how much of your next dollar of income may go to tax.

How to use the calculator correctly
1) Enter gross income
Use your expected annual salary or total employment income before tax.
2) Add other taxable income
Include side business income, freelance revenue, taxable investment income, or rental profit if applicable.
3) Add deductions
Enter RRSP contributions and deductible items that reduce taxable income. This can materially lower tax and change your marginal bracket outcome.
4) Review both rates
- Effective tax rate: total tax divided by taxable income
- Marginal tax rate: approximate tax on the next dollar earned
Both are useful, but for decisions like overtime, bonuses, and side gigs, marginal rate is often the more practical number.
Why marginal vs effective tax rate matters
Many people think “I moved into a higher bracket, so all my income is taxed more.” That is not how progressive taxation works. Only the income inside each bracket is taxed at that bracket’s rate.
Your effective rate is usually much lower than your top bracket rate. Understanding this removes confusion and helps with smarter financial planning.
Ways to lower your Ontario tax bill legally
- Use RRSP contributions strategically near year-end
- Track work-related deductions where eligible
- Use tax-efficient account types (TFSA, RRSP, FHSA where relevant)
- Split income lawfully when possible (for families/business owners)
- Plan bonus timing if your income can shift between years
Important limitations
This is a planning tool, not a CRA filing engine. Real tax returns can include many additional credits and adjustments such as tuition, disability, medical expenses, charitable donations, and payroll effects like CPP/EI.
For large financial decisions, verify results with a professional accountant or a certified tax preparation platform.
