How Marginal Tax Rates Work

Marginal tax rates represent the rate applied to your last dollar of income. The Ontario tax system is progressive, meaning higher income earners pay higher rates on their entire income.

Marginal Tax Rate Formula:

Marginal Tax Rate = (Tax on Last Dollar of Income) / (Last Dollar of Income)

For example, if you earn $50,000 and pay $4,500 in taxes, your marginal tax rate is 9%. This means the last dollar of your income is taxed at 9%.
