Ontario Tax Brackets

Ontario uses a progressive tax system, meaning higher income levels are taxed at higher rates. The 2023 tax brackets for individuals are as follows:

Over $220,000 13.16%

The Ontario government also imposes a provincial sales tax (PST) of 8% on most goods and services, which is included in the final price of most items.

How to Calculate Ontario Income Tax

Calculating your Ontario income tax involves several steps:

  1. Determine your taxable income: Subtract allowable deductions from your total income.
  2. Apply the Ontario tax brackets: Calculate the tax owed in each bracket.
  3. Add provincial sales tax (PST): Include the 8% PST on taxable income.
  4. Apply credits and deductions: Subtract any applicable tax credits or deductions.

Formula for Ontario Income Tax Calculation

Ontario Tax Credits and Deductions

Ontario offers various tax credits and deductions that can reduce your tax liability:

  • Basic Personal Amount: $12,323 for 2023, reducing taxable income.
  • Ontario Child Benefit: Up to $1,000 per child under 18.

Example Calculation

Let's calculate the income tax for someone earning $80,000 in Ontario:

  1. Subtract the Basic Personal Amount: $80,000 - $12,323 = $67,677 taxable income.
  2. Apply Ontario tax brackets:
    • $49,059 × 5.05% = $2,458.29
    • ($67,677 - $49,059) × 9.15% = $1,640.58
    • Total tax before PST = $2,458.29 + $1,640.58 = $4,098.87
  3. Add 8% PST: $67,677 × 8% = $5,414.16
  4. Total tax = $4,098.87 + $5,414.16 = $9,513.03

This example shows the tax before applying any credits or deductions.
