Ontario Tax Return Calculator 2019

How to Use This Calculator

Enter your total taxable income for 2019 in the first field. Then add any eligible deductions and tax credits. The calculator will compute your estimated tax payable or refund.

This is an estimate only. Actual tax calculations may differ based on your specific situation and changes in tax laws. Always consult a tax professional for final tax preparation.

Formula Used

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

The Ontario tax rates for 2019 were:

• 15% on the first $43,906 of taxable income
• 28.5% on the next $43,903
• 33% on the amount over $87,809

Worked Example

For a taxpayer with $90,000 taxable income, $5,000 in deductions, and $2,000 in tax credits:

1. Taxable income after deductions: $90,000 - $5,000 = $85,000
2. Taxable income after credits: $85,000 - $2,000 = $83,000
3. Tax calculation:
   • $43,906 × 15% = $6,585.90
   • $43,903 × 28.5% = $12,470.76
   • ($83,000 - $87,809) × 33% = $0 (since $83,000 is below the third bracket)
4. Total tax payable: $6,585.90 + $12,470.76 = $19,056.66

This example shows an estimated tax payable of $19,056.66.
