Key Payroll Deductions in Ontario

Ontario payroll deductions include several mandatory contributions and taxes that employers must account for when processing payroll. The main deductions are:

Canada Pension Plan (CPP)

The CPP is a retirement savings program where both employees and employers contribute. The employee contribution rate is 5.15% of the employee's earnings, up to the maximum insurable earnings limit.

Employment Insurance (EI)

The EI program provides income replacement to workers who become unemployed through no fault of their own. The employee contribution rate is 1.66% of the employee's earnings, up to the maximum insurable earnings limit.

Income Tax

Ontario income tax is calculated based on the employee's taxable income. The tax rates vary depending on the employee's tax bracket. Federal income tax is also deducted from the employee's paycheck.

Calculation Method

The Ontario Payroll Deductions Calculator 2025 uses the following formulas to calculate the deductions:

CPP Contribution

CPP = Employee Earnings × 0.0515 (employee rate)

Maximum insurable earnings for CPP in 2025: $65,900

EI Contribution

EI = Employee Earnings × 0.0166 (employee rate)

Maximum insurable earnings for EI in 2025: $61,800

Income Tax

Ontario income tax is calculated using progressive tax brackets. Federal income tax is also deducted based on the employee's taxable income.

The total payroll deductions are the sum of CPP, EI, and income tax deductions.

Example Calculation

Let's calculate the payroll deductions for an employee with a gross pay of $4,000 in 2025.

Step 1: Calculate CPP Contribution

CPP = $4,000 × 0.0515 = $206

Step 2: Calculate EI Contribution

EI = $4,000 × 0.0166 = $66.40

Step 3: Calculate Income Tax

Assuming the employee is in the basic personal amount bracket, the Ontario income tax would be calculated as follows:

Taxable income = $4,000 - $12,069 (basic personal amount) = $2,931

Ontario income tax = $2,931 × 0.0505 = $148.54

Federal income tax = $2,931 × 0.15 = $439.65

Step 4: Total Deductions

Total deductions = CPP + EI + Ontario tax + Federal tax = $206 + $66.40 + $148.54 + $439.65 = $850.59

The net pay for the employee would be $4,000 - $850.59 = $3,149.41.
