Formula Used

The Ontario tax return is calculated using the following formula:

Taxable Income = Total Income - Deductions

Tax Owed = Taxable Income × Tax Rate - Credits

The tax rate is determined based on your taxable income and filing status, using the 2021 Ontario tax brackets.

Worked Example

Let's calculate a tax return for a single filer with $50,000 in taxable income, $5,000 in deductions, and $1,000 in tax credits.

Taxable Income = $50,000 - $5,000 = $45,000
Tax Rate for $45,000 = 5.05% (2021 Ontario rate)
Tax Owed = $45,000 × 5.05% = $2,272.50
Final Tax Return = $2,272.50 - $1,000 = $1,272.50

This example shows an estimated tax return of $1,272.50. The actual amount may vary based on your specific circumstances.
