How Ontario Income Tax Refund Works

Ontario income tax is calculated using progressive tax brackets. The refund is determined by comparing the tax you owe to the tax withheld from your paycheck. If you withheld more tax than you owe, you'll receive a refund.

Tax Calculation Formula

Tax Owed = (Taxable Income × Tax Rate) - Deductions - Credits

Refund = (Tax Withheld - Tax Owed)

Worked Examples

Example 1: Single Filer

John is a single filer with a taxable income of $50,000. He has no deductions or credits.

Tax Owed = ($50,000 × 5.06%) = $2,530

Refund = ($3,000 withheld - $2,530 owed) = $470

Example 2: Married Filer

Sarah and David are married with a combined taxable income of $120,000. They have $5,000 in deductions and $2,000 in credits.

Tax Owed = ($120,000 × 11.16%) - $5,000 - $2,000 = $12,496

Refund = ($10,000 withheld - $12,496 owed) = -$2,496 (Sarah and David owe $2,496 more)
