Formula Used

The Ontario income tax return is calculated using progressive tax brackets. The formula is:

Where bracket rates are determined by your filing status and taxable income level. The calculator applies these rates automatically based on your inputs.

Worked Example

Let's calculate a tax return for a single filer with $50,000 in taxable income:

First $44,701 at 5.05% = $2,263.56
Next $5,299 at 9.15% = $483.55
Remaining $0 at 11.16% = $0.00
Total tax owed = $2,747.11

If you have $2,000 in deductions, your taxable income becomes $48,000, potentially reducing your tax owed.

Common Deductions

Several deductions can reduce your taxable income:

RRSP contributions (up to $27,720 in 2024)
Medical expenses over 3% of income
Donations to registered charities
Home office expenses
Moving expenses for military personnel

Note: Deductions must be claimed on your official tax return and may have specific eligibility requirements.

Tax Credits

Ontario offers several tax credits that can reduce your tax liability:

Ontario Child Benefit (up to $2,500 per child)
Ontario Disability Support Program credit
Ontario Trillium Benefit for seniors
Homeowners' property tax credit

These credits are applied after deductions but before any refunds are issued.
