Calculate Bonus Tax Ontario

Reviewed by Calculator Editorial Team

Bonuses are a common form of compensation for employees, but understanding how they're taxed in Ontario can be confusing. This guide explains the Ontario bonus tax calculation, including tax rates, deductions, and how to determine your taxable bonus amount.

How Ontario Bonus Tax Works

In Ontario, bonuses are taxed as part of your total income for the year. The Canada Revenue Agency (CRA) treats bonuses as taxable income, which means you'll need to report them on your tax return. The amount of tax you owe on your bonus depends on your total taxable income and the applicable tax brackets.

Key Points

Bonuses are subject to income tax, but not to employment insurance premiums or Canada Pension Plan contributions. The tax on bonuses is calculated using the same progressive tax rates as your regular income.

Bonus Tax Calculation Process

The process of calculating bonus tax in Ontario involves several steps:

  1. Determine your total taxable income for the year, including your bonus
  2. Apply the Ontario tax rates to your total taxable income
  3. Calculate the tax owed on your bonus by comparing the tax on your total income to the tax on your income without the bonus

Bonus Tax Calculation

The formula for calculating bonus tax in Ontario is:

Formula

Bonus Tax = (Total Income + Bonus) × Ontario Tax Rate - (Total Income × Ontario Tax Rate)

Where:

  • Total Income = Your total taxable income before the bonus
  • Bonus = The amount of your bonus
  • Ontario Tax Rate = The applicable Ontario tax rate based on your total income

Step-by-Step Calculation

  1. Add your bonus to your total taxable income to get your new total income
  2. Calculate the tax on your new total income using the Ontario tax rates
  3. Calculate the tax on your original total income using the Ontario tax rates
  4. Subtract the tax on your original income from the tax on your new income to get your bonus tax

Tax Rates and Brackets

Ontario uses a progressive tax system, meaning your tax rate increases as your income increases. The 2023 Ontario tax rates are:

Taxable Income Tax Rate
$0 - $48,535 5.05%
$48,535.01 - $97,069 9.15%
$97,069.01 - $150,473 11.16%
$150,473.01 - $220,000 12.16%
Over $220,000 13.16%

For example, if your total income is $100,000 and you receive a $5,000 bonus, your new total income is $105,000. The tax on $105,000 is $10,252.55, and the tax on $100,000 is $9,707.55. The tax on your bonus is $545.

Example Calculation

Let's walk through an example to illustrate how to calculate bonus tax in Ontario.

Scenario

  • Total taxable income before bonus: $90,000
  • Bonus amount: $7,000

Step 1: Calculate tax on total income before bonus

$90,000 falls into the $48,535.01 - $97,069 bracket at 9.15%.

Tax = $90,000 × 9.15% = $8,235

Step 2: Add bonus to total income

New total income = $90,000 + $7,000 = $97,000

Step 3: Calculate tax on new total income

$97,000 falls into the $97,069.01 - $150,473 bracket at 11.16%.

Tax = $97,000 × 11.16% = $10,849.20

Step 4: Calculate bonus tax

Bonus tax = $10,849.20 - $8,235 = $2,614.20

Result

In this example, the bonus tax owed is $2,614.20.
