Key Payroll Deductions in Ontario

Canada Pension Plan (CPP)

The CPP is a social insurance program that provides retirement income to eligible Canadians. Employers must deduct CPP contributions from employee wages.

Employment Insurance (EI)

EI provides income protection and job placement services to workers who become unemployed through no fault of their own. Employers deduct EI premiums from employee wages.

Income Tax

Income tax is deducted from employee wages to fund provincial and federal government services. The tax rate depends on the employee's taxable income.

CPP Retirement Contributions

Additional CPP contributions may be required for employees who are 65 years or older or who have reached the maximum pensionable earnings limit.

Provincial Sales Tax (PST)

Certain employees may be subject to PST deductions, particularly those in the hospitality industry.

Calculation Method

The Ontario Payroll Deductions Calculator uses the following formulas to determine the required deductions:

CPP Employee Contribution = Wages × CPP Rate CPP Employer Contribution = Wages × CPP Rate EI Premium = Wages × EI Rate Income Tax = (Taxable Income - Basic Personal Amount) × Tax Rate CPP Retirement Contribution = Wages × Retirement Rate (if applicable) PST = Wages × PST Rate (if applicable)

The calculator uses the current rates for each deduction type. For the most accurate results, ensure you enter the correct wages and taxable income amounts.

Note: The actual calculation may vary based on specific employment circumstances and changes in government rates. Always verify with official government sources or a payroll professional for critical payroll calculations.

Worked Example

Let's calculate the payroll deductions for an employee earning $2,500 in a month with a taxable income of $2,200.

Assumptions:

CPP Rate: 5.10%
EI Rate: 1.66%
Income Tax Rate: 20.5% (for taxable income over $12,000)
Basic Personal Amount: $12,000
No CPP Retirement or PST deductions

Calculations:

CPP Employee Contribution: $2,500 × 5.10% = $127.50
CPP Employer Contribution: $2,500 × 5.10% = $127.50
EI Premium: $2,500 × 1.66% = $41.50
Income Tax: ($2,200 - $1,200) × 20.5% = $205.00

Total Deductions:

The total payroll deductions for this employee would be $127.50 (CPP employee) + $127.50 (CPP employer) + $41.50 (EI) + $205.00 (income tax) = $501.50.
