Calculate your Ontario income tax with Canada Pension Plan (CPP) and Employment Insurance (EI) deductions using our accurate tax calculator. This tool helps you understand how much tax you'll owe after deductions for CPP and EI contributions.
How This Calculator Works
The Ontario Income Tax Calculator with CPP and EI takes your gross income and calculates the provincial income tax you owe, minus deductions for Canada Pension Plan (CPP) and Employment Insurance (EI) contributions.
Ontario uses a progressive tax system with different tax rates for different income brackets. The calculator applies these rates to your gross income and subtracts the CPP and EI contributions to give you your net provincial tax liability.
Note: This calculator provides an estimate. For exact tax calculations, consult a tax professional or use official government tax software.
Formula Used
The calculation follows these steps:
- Calculate provincial tax based on Ontario's progressive tax brackets
- Calculate CPP contributions (5.95% of insurable earnings up to $63,500)
- Calculate EI premiums (1.66% of insurable earnings up to $57,400)
- Subtract CPP and EI from provincial tax to get net tax liability
Provincial Tax Calculation:
Tax = (Income × Tax Rate) - (Tax Credits + Deductions)
Where Tax Rate is determined by Ontario's progressive tax brackets.
CPP Calculation:
CPP = 5.95% of insurable earnings (max $63,500)
EI Calculation:
EI = 1.66% of insurable earnings (max $57,400)
Worked Example
Let's calculate the Ontario income tax for someone earning $60,000 with CPP and EI deductions.
| Income Bracket | Tax Rate | Taxable Income | Tax Amount |
|---|---|---|---|
| $0 - $44,703 | 5.06% | $44,703 | $2,263.75 |
| $44,704 - $89,407 | 9.15% | $15,293 | $1,394.95 |
| $89,408 - $140,000 | 11.16% | $5,593 | $622.85 |
| Total Provincial Tax | $4,271.55 |
CPP Contribution: 5.95% of $60,000 = $3,570.00
EI Premium: 1.66% of $60,000 = $996.00
Total Deductions: $3,570.00 + $996.00 = $4,566.00
Net Provincial Tax: $4,271.55 - $4,566.00 = -$294.45 (Refund)
This example shows that with this income level, the CPP and EI deductions exceed the provincial tax owed, resulting in a refund.
