Common Deductions for Bonus Payments

• Charitable Donations: Donations to registered charities may be deductible, depending on the amount and type of donation.

Worked Example

Let's calculate the tax on a $10,000 bonus payment for someone with a $90,000 taxable income before the bonus.

1. Total taxable income with bonus: $90,000 + $10,000 = $100,000
2. Tax bracket for $100,000: $53,359 - $106,717 at 29.65% combined rate
3. Tax on $100,000: $29,650
4. Tax on $90,000: $18,050
5. Tax on bonus: $29,650 - $18,050 = $11,600

This example shows that a $10,000 bonus in this income bracket would result in an additional $11,600 in taxes.
