Worked Example

Let's calculate the effective tax rate for a single taxpayer with $50,000 in taxable income for 2017.

First, determine the tax owed using Ontario's 2017 brackets:
- $44,701 - $44,700 = $1 taxed at 5.06%
- $50,000 - $44,701 = $5,299 taxed at 9.15%
Calculate the total tax:
- ($44,700 × 5.06%) + ($5,299 × 9.15%) = $2,251.74 + $484.15 = $2,735.89
Calculate the effective tax rate:
- ($2,735.89 / $50,000) × 100% = 5.47%

For this example, the effective tax rate is 5.47%.
