How Ontario tax return works

Ontario's tax system is progressive, meaning higher income brackets are taxed at higher rates. The basic tax rates for 2023 are:

5.05% on the first $49,208 of taxable income
9.15% on the next $49,208 to $98,417
11.16% on the next $98,418 to $150,000
12.16% on the next $150,001 to $220,000
13.16% on amounts over $220,000

In addition to the basic tax rates, Ontario has provincial sales tax (PST) and harmonized sales tax (HST) rates that vary by product category.

Common tax deductions in Ontario

There are several common deductions that Ontario taxpayers can claim:

Medical expenses over 3% of income
Donations to registered charities
Home office expenses
Education expenses for yourself or dependents
Moving expenses when relocating for work

These deductions can significantly reduce your taxable income and potentially increase your refund.

Important filing deadlines

Ontario tax returns are due by April 30 of each year. However, there are several important dates to remember:

March 2: Deadline to file for the previous year's tax return
April 30: Final deadline for filing
June 15: Deadline for paying any balance due

Missing these deadlines can result in penalties and interest charges on your tax liability.
