What Are Payroll Deductions?
Payroll deductions are amounts withheld from an employee's gross pay to cover various mandatory contributions and taxes. These deductions ensure employees receive their full earnings while covering government obligations and employee benefits.
In Ontario, employers must withhold several types of deductions from employee paychecks, including:
- Income tax
- Canada Pension Plan (CPP) contributions
- Employment Insurance (EI) premiums
- Provincial sales tax (PST) where applicable
- Union dues (if applicable)
- Other mandatory deductions as required by law
Required Ontario Payroll Deductions
The specific deductions required for Ontario payroll depend on the employee's situation and the applicable tax year. The main deductions include:
Income Tax
Ontario income tax is calculated based on the employee's taxable income and the applicable tax brackets. The federal income tax is also withheld from payroll.
Canada Pension Plan (CPP)
CPP contributions are calculated at a flat rate of 5.1% of the employee's earnings, up to the maximum insurable earnings limit.
Employment Insurance (EI)
EI premiums are calculated at a flat rate of 1.66% of the employee's earnings, up to the maximum insurable earnings limit.
Employers must also consider other deductions such as provincial sales tax (PST) for certain employees and any union dues that may apply.

This Ontario payroll deductions calculator uses the current tax rates and contribution rates for the selected tax year to calculate the required deductions. The calculation follows these steps:
- Determine the applicable tax rates for the selected tax year
- Calculate the federal and provincial income tax based on the employee's taxable income
- Calculate the CPP contributions at 5.1% of earnings
- Calculate the EI premiums at 1.66% of earnings
- Sum all deductions to get the total amount to withhold

Example Calculation
Let's look at an example calculation for an employee with a gross pay of $2,500 in the 2023 tax year:
| Deduction Type | Calculation | Amount |
|---|---|---|
| Federal Income Tax | Based on tax brackets | $450.00 |
| Ontario Income Tax | Based on tax brackets | $250.00 |
| CPP Contributions | 5.1% of $2,500 | $127.50 |
| EI Premiums | 1.66% of $2,500 | $41.50 |
| Total Deductions | $868.50 |
In this example, the total deductions for an employee earning $2,500 would be $868.50. The calculator shows the breakdown of each deduction type for clarity.
Frequently Asked Questions
What is the difference between gross pay and net pay?
Gross pay is the total amount an employee earns before any deductions. Net pay is the amount the employee actually receives after all deductions have been withheld.
Are there any deductions that vary by employee?
Yes, some deductions may vary depending on the employee's situation. For example, union dues are only applicable to employees who are union members, and PST may only apply to certain types of employees.
Can I use this calculator for self-employed individuals?
No, this calculator is specifically designed for employers to calculate payroll deductions for their employees. Self-employed individuals should use the Canada Revenue Agency's self-employment tax calculator.
How often should I calculate payroll deductions?
Payroll deductions should be calculated for each pay period to ensure accurate withholding. The frequency depends on your pay schedule (weekly, bi-weekly, monthly, etc.).
