What is Ontario Surtax?

Ontario surtax is a progressive tax that applies to certain types of income in Ontario. It is calculated as an additional percentage on top of the provincial tax rate. The surtax is designed to target specific income brackets or types of income that the government wants to tax more heavily.

How to Calculate Ontario Surtax

To calculate Ontario surtax, you need to know the taxable income and the applicable surtax rate. The formula for calculating Ontario surtax is:

Ontario Surtax = Taxable Income × Surtax Rate

The taxable income is the amount of income that is subject to Ontario provincial tax. The surtax rate is the additional percentage that is applied to the taxable income. The surtax rate varies depending on the type of income and the income bracket.

Here are the steps to calculate Ontario surtax:

Determine your taxable income for the year.
Identify the applicable surtax rate based on your income bracket and type of income.
Multiply your taxable income by the surtax rate to calculate the Ontario surtax.

The Ontario government provides a tax calculator on its website that can help you calculate your Ontario surtax. You can also consult a tax professional for personalized advice.

Example Calculation

Let's say you have a taxable income of $100,000 and the applicable surtax rate is 10%. Here's how you would calculate the Ontario surtax:

Ontario Surtax = $100,000 × 10% = $10,000

In this example, the Ontario surtax would be $10,000. This amount would be added to your provincial tax liability.

It's important to note that the surtax rate and thresholds may change depending on the type of income and the income bracket. Always verify the current rates with the Ontario government or a tax professional.
