Worked Example
Let's calculate the tax for a single filer with $60,000 in taxable income:
- Determine the tax bracket: $60,000 falls in the $44,702 - $89,404 bracket with a 9.15% rate.
- Calculate the taxable amount in this bracket: $60,000 - $44,701 = $15,299.
- Calculate the tax for this bracket: $15,299 × 9.15% = $1,399.66.
- Add the tax from the previous bracket: $44,701 × 5.05% = $2,266.51.
- Total tax: $2,266.51 + $1,399.66 = $3,666.17.
- Subtract the basic personal amount: $3,666.17 - $11,474 = $2,519.17.
This example shows that a single filer with $60,000 in taxable income would owe approximately $2,519.17 in Ontario taxes for 2018.
