Understanding Ontario's marginal tax rates is essential for anyone working in the province. This calculator helps you determine how much tax you'll owe based on your income, and our guide explains how the tax system works in Ontario.
How Ontario Marginal Tax Rates Work
Ontario's income tax system uses a progressive tax rate structure, meaning your tax rate increases as your income increases. This system is designed to ensure that higher-income earners contribute a larger share of their income to government revenue.
Marginal Tax Rate Formula
The marginal tax rate is calculated as the additional tax owed on the next dollar of income earned. It's determined by the tax bracket in which your income falls.
When you file your taxes, your income is divided into different tax brackets, each with its own tax rate. The tax you owe is calculated by multiplying each portion of your income by its respective tax rate.

Worked Examples
Let's look at a couple of examples to see how the Ontario marginal tax rates work in practice.
Example 1: Low Income
If you earn $30,000 in Ontario, your marginal tax rate would be 5.05%. This means you pay 5.05% on all your income.
Calculation
Tax Owed = $30,000 × 5.05% = $1,515
Example 2: Higher Income
If you earn $100,000 in Ontario, your marginal tax rate would be 9.15%. However, you'll pay lower rates on the first $49,020 of your income.
Calculation
First $49,020: $49,020 × 5.05% = $2,451.11
Next $50,980: $50,980 × 9.15% = $4,652.87
Total Tax Owed = $2,451.11 + $4,652.87 = $7,103.98
