How Ontario Income Tax Works

Ontario's income tax system is progressive, meaning higher-income earners pay a higher percentage of their income in taxes. The province uses a combination of federal and provincial tax rates to determine your tax liability.

The Ontario government collects income tax through payroll deductions, tax returns, and other reporting mechanisms. The tax year runs from April 1 to March 31, with tax returns typically due by June 15.
