Simplify your payroll: The Canadian business owner's guide to tax calculations

Payroll taxes are an easy subject to push aside when first setting up a new business. If you're like many new business owners, you probably find calculating payroll taxes to be a daunting task—know that you're not alone. This comprehensive guide will simplify the process and introduce you to the important steps to follow to calculate your payroll.

Understanding payroll taxes in Canada

Payroll taxes in Canada comprise various deductions made from an employee's paycheque, which contribute to federal and provincial programs such as the Canada Pension Plan (CPP)/Québec Pension Plan (QPP) and Employment Insurance (EI)/Québec Parental Insurance Plan (QPIP).

Here's what you need to know:

What is payroll tax?

Payroll tax is a mandatory deduction made by employers from their employees' wages. These deductions are paid to the federal government on behalf of the employees' and count as the employees' contributions towards income tax, CPP/QPP, and EI/QPIP.

Why is payroll tax important?

Beyond being a legal obligation, timely and accurate payroll tax deductions can ensure that essential services and benefits, like the CPP/QPP and EI/QPIP, remain funded and available for everyone.

How is payroll tax calculated?

Understanding payroll tax calculations is vital for accurate payouts and ensuring compliance. The Canada Revenue Agency (CRA) provides detailed guidance on how to calculate payroll deductions.

Here's a simple step-by-step breakdown:

1. Determine employee pay

Before any deductions are made, identify the total gross pay for the employee. In order to calculate gross pay, you will need to know hourly or salaried rate of pay, number of hours worked, and the pay period frequency.

2. Calculate federal and provincial income tax

There are a number of online calculators available to help you calculate the necessary payroll deductions. Depending on the province of employment, use the tax tables provided by the CRA to determine the appropriate income tax deduction, or try this free QuickBooks payroll calculator.

The rate of income tax is different for each employee depending on which credits and deductions they are eligible for under the Canadian Income Tax Act. Employees must complete a TD1 form/TP-1015.3-V (if in Québec) every year. This form aids employers in estimating the amount of federal and provincial tax to deduct from the employee's pay.

3. Determine Canada Pension Plan (CPP)/Québec Pension Plan (QPP) contributions

Based on an employee's earnings, calculate their Canada Pension Plan contribution. Employees currently have a basic CPP/QPP exemption of $3,500 annually. This means, employees earning $3,500 or less per year do not need to have CPP/QPP deducted from their earnings.

Additionally, employees are currently exempt from CPP/QPP if they are 18 and under or 70 and older, or they are collecting CPP/QPP benefits. The CPP/QPP annual rate and maximum contributions are subject to change every year. For 2024, the CPP rate is 5.95% with an annual maximum contribution of $3,867.50 per employee. If in Québec For 2024, the QPP rate is 6.40% with an annual maximum contribution of $4,160 per employee.



As of January 2024, pensionable earnings between $68,500 and $73,200 are now subject to second additional CPP/QPP contributions (CPP2/QPP2) as announced by the Canada Revenue Agency. The contribution rate for this will be 4% in 2024 with a maximum contribution of $188 per employee.

4. Calculate Employment Insurance (EI)/Québec Parental Insurance Plan (QPIP) premiums

Employment Insurance provides temporary income to workers while they are in between jobs. It is also used to support those on pregnancy or sick leave. Calculating Employment Insurance/Québec Parental Insurance Plan premiums is simpler to calculate than Canada Pension Plan/Québec Pension Plan contributions, since every dollar earned is subject to EI/QPIP deductions. Note that if an employee is related to their employer—their earnings are not considered insurable. In that case, they would be EI/QPIP exempt, and the employer would not need to deduct EI/QPIP from their earnings. The 2024 EI rate is 1.66% to a maximum of $1,049.12 per employee for the year. If in Québec The 2024 QPIP rate is 1.32% to a maximum of $834.24 per employee for the year. You can use QuickBooks free payroll calculator to easily calculate EI/QPIP premiums.

5. Add additional deductions if applicable

Some employees might have union dues, charitable donations, or other deductions from their pay depending on your organization. Some businesses also handle pension and savings account deductions for their employees as well. Ensure you account for these additional deductions.
