Ontario Income Tax Calculator (Canada)
Estimate your annual and per-paycheque net income based on federal + Ontario tax brackets, CPP, and EI.
Estimate only. Does not include every credit/surtax scenario (for example Ontario Health Premium, spouse/tuition credits, and special deductions).
How this Canada Ontario tax calculator works
This calculator estimates take-home pay for people earning income in Ontario, Canada. It combines four major payroll components:
- Federal income tax using progressive tax brackets
- Ontario provincial income tax using Ontario brackets
- CPP contributions (including first and second earnings tiers)
- EI premiums up to the annual maximum insurable earnings limit
Because Canada uses progressive rates, each portion of your taxable income is taxed at a different rate. That means moving into a higher bracket does not make all your income taxed at that higher rate—only the amount above the bracket threshold.
Inputs explained
Employment income
This is your gross salary or wages before deductions. CPP and EI are calculated from this amount.
Additional taxable income
Use this for other taxable amounts such as side income or taxable investment income. This amount affects tax but does not increase CPP/EI in this calculator.
RRSP contributions
RRSP contributions reduce taxable income. If contributions are made through payroll, they can also reduce immediate tax withholding and improve current cash flow.
Other pre-tax deductions
This can include employer-plan deductions that reduce taxable income. Enter only deductions that are truly pre-tax.
What you get in the results
- Taxable income used for calculation
- Estimated federal and Ontario tax after basic credits
- CPP and EI contributions
- Total deductions
- Estimated net annual income and net per pay period
- Average tax rate and approximate marginal rate
Example scenario
If you enter:
- Employment income: $90,000
- Additional income: $5,000
- RRSP: $7,500
- Other deductions: $1,000
The calculator estimates the federal/provincial taxes and payroll deductions, then returns net pay annually and per selected pay period. This is useful for budgeting, salary comparison, or planning RRSP contribution amounts before year-end.
Ways to reduce your Ontario tax bill
1) Use registered accounts strategically
RRSP contributions can lower current-year taxable income. TFSA contributions do not reduce current taxes, but they help build tax-free future growth.
2) Split timing of deductions and income
If possible, coordinate bonus timing, business expenses, and deductible contributions across tax years for better bracket efficiency.
3) Check available non-refundable credits
Credits for tuition, disability, medical costs, charitable giving, and caregiving may reduce taxes payable.
Important limitations
This page is designed as a fast planning tool, not a CRA filing engine. Real returns may differ due to:
- Ontario Health Premium and surtax interactions
- Age amount, pension amount, tuition transfer, or spousal credits
- Self-employment CPP differences
- Benefit clawbacks and provincial benefit calculations
- Employer-specific payroll handling
