Withholding Tax Calculator Ontario

Ontario's withholding tax system requires employers to deduct a portion of employee earnings before paying them. This calculator helps you determine the correct withholding tax amount for payroll purposes in Ontario.

What is Withholding Tax?

Withholding tax is a tax deducted from an employee's wages before they receive payment. In Ontario, employers must withhold income tax from employee earnings based on the employee's tax bracket. This ensures that the appropriate amount of income tax is paid to the Canada Revenue Agency (CRA) on behalf of the employee.

Key Points

Withholding tax is different from payroll tax, which includes employment insurance and CPP contributions. It's calculated based on the employee's tax bracket and the number of pay periods in the year.

The withholding tax system in Ontario is designed to simplify payroll processing for employers while ensuring employees pay the correct amount of income tax. The system uses tax tables provided by the CRA to determine the appropriate withholding amounts.

How to Calculate Withholding Tax

Calculating withholding tax in Ontario involves several steps. Here's a step-by-step guide:

Determine the employee's gross earnings for the pay period.
Subtract the basic personal amount from the gross earnings.
Apply the appropriate withholding rate to the taxable amount.
Round the result to the nearest cent.

For example, if an employee earns $2,500 in a pay period and falls into the 20.5% tax bracket:

Example Calculation

Taxable Amount = $2,500 - $1,206.90 = $1,293.10

Withholding Tax = $1,293.10 × 20.5% = $266.15

This withholding tax amount would then be deducted from the employee's paycheck.
