Tax Savings = (Total Income × Ontario Tax Rate) - (Taxable Income × Ontario Tax Rate)

Worked Examples

Example 1: Basic Personal Amount Deduction

If you have a total income of $50,000 and claim the basic personal amount deduction of $12,069, your taxable income would be:

Taxable Income = $50,000 - $12,069 = $37,931

Tax Savings = ($50,000 × 5.05%) - ($37,931 × 5.05%) = $2,525 - $1,913 = $612

Example 2: Medical Expenses Deduction

If you have a total income of $60,000 and claim medical expenses of $3,000, your taxable income would be:

Taxable Income = $60,000 - $3,000 = $57,000

Tax Savings = ($60,000 × 5.05%) - ($57,000 × 5.05%) = $3,030 - $2,913 = $117
