When do Ontario tax brackets change?
Any changes to tax rates or income brackets must be announced in a budget. Both federal and provincial/territorial governments can make changes to their level of taxation, tax deductions or credits, programs and exemptions, but they are always done in a budget announcement. They aren’t enacted until the budget bill receives Royal Assent.
Are Ontario tax brackets progressive?
Yes, the rate of tax increases as the amount of income increases.
What If My Income Falls Into Multiple Tax Brackets?
If your income falls in a higher tax bracket, you will be taxed on the lowest tax bracket rate to the maximum for that bracket, on the second tax bracket to the maximum amount for that bracket, and so on progressively until all your income is taxed at each rate for each bracket that it spills into. Remember that there are different rates for federal and provincial/territorial taxes.
