Canadian Payroll Calculator 2025

Running payroll in Canada means withholding the right amounts for income tax, Canada Pension Plan (CPP), and Employment Insurance (EI) from every employee's paycheque — then remitting the employer's share on top. Getting it wrong means interest charges and penalties from the CRA. This calculator gives you a solid estimate for 2025 payroll calculations.

Understanding Canadian Payroll Deductions

Every time you pay an employee in Canada, three types of deductions must be calculated, withheld, and remitted to the CRA:

Income Tax (Federal + Provincial)

You must withhold income tax based on the employee's total expected annual income and their TD1 form declarations. The CRA provides payroll deduction tables, but most employers use payroll software. Tax is withheld at source to prevent employees from owing a large amount at tax time.

Canada Pension Plan (CPP)

For 2025, employees contribute 5.95% of insurable earnings between $3,500 (exemption) and approximately $68,500 (maximum pensionable earnings). The maximum annual CPP contribution is approximately $3,867 for employees. Employers must match this contribution dollar for dollar. Employees aged 65–70 who are receiving CPP/QPP can opt out using Form CPT30.

Employment Insurance (EI)

Employees pay 1.66% of insurable earnings up to approximately $63,200. Maximum annual employee premium: about $1,049. Employers pay 1.4 times the employee premium — so for every $1 withheld from an employee, the employer owes $1.40 to the CRA. Employers with qualified short-term disability plans can apply for an EI premium reduction.

Payroll Compliance: What Employers Must Do

1. Get a Business Number from CRA and open a payroll account (RP)
2. Have each new employee complete a TD1 (federal) and provincial TD1 form
3. Calculate and withhold the correct amounts each pay period
4. Remit deductions + employer shares to CRA by the 15th of the following month
5. Issue T4 slips to all employees by February 28 of the following year
6. File T4 Summary with CRA by February 28

Employee vs. Contractor: The Payroll Impact

If a worker is classified as an employee, you must run payroll and handle all CPP, EI, and income tax withholding. If they're a self-employed contractor, you simply pay them and issue a T4A if you paid them $500 or more. However, misclassifying an employee as a contractor is a serious CRA risk — you'd owe back payroll deductions plus interest and penalties.
