Formula Used

The calculator uses the following simplified formula to estimate your tax return:

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

Where:

Taxable Income = Total income - Non-taxable income
Tax Rate = Ontario provincial tax rate (varies by income level)
Deductions = RRSP contributions, medical expenses, etc.
Tax Credits = Canada Child Benefit, disability credits, etc.

Important Notes

This is a simplified estimate. The actual tax return may differ based on your specific circumstances and the exact tax rules that apply to you. Always consult with a tax professional for precise calculations.

Worked Example

Let's calculate an example tax return for a single filer with $50,000 taxable income, $5,000 in deductions, and $2,000 in tax credits.

Taxable Income = $50,000
Deductions = $5,000
Taxable Income after Deductions = $50,000 - $5,000 = $45,000
Tax Rate (for $45,000 in Ontario) = 20.05%
Tax Owed = $45,000 × 20.05% = $9,022.50
Tax Credits = $2,000
Estimated Tax Return = $9,022.50 - $2,000 = $7,022.50

This example shows an estimated refund of $7,022.50. The actual amount may vary based on your specific situation.
