Ontario Tax Brackets 2024

Ontario's progressive tax system applies different rates to different income levels. Here are the 2024 tax brackets:

Taxable Income	Tax Rate
$0 - $49,020	5.05%
$49,020.01 - $98,040	9.15%
$98,040.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
Over $220,000	13.16%

These rates apply to Ontario residents. Federal tax rates are different and must be calculated separately.

How Ontario Income Tax Works

Ontario's income tax system is progressive, meaning higher incomes are taxed at higher rates. The tax is calculated by applying each rate to the portion of income that falls within that bracket.

Tax Calculation Formula

Tax = (Income × Rate) for each bracket, summed together

For example, someone earning $50,000 would pay:

$49,020 × 5.05% = $2,451.01
Remaining $980 × 9.15% = $89.14
Total tax = $2,451.01 + $89.14 = $2,540.15

The Ontario government uses this progressive system to fund public services and programs. The rates are adjusted annually based on provincial revenue needs.

Deductions and Tax Credits

Several deductions and credits can reduce your Ontario income tax liability:

Type	Description	Maximum Value
Basic Personal Amount	Reduces taxable income	$12,222 (2024)
CPP Contributions	Deduction for pension plan contributions	Up to 5.95% of pensionable earnings
RRSP Contributions	Deduction for retirement savings	Up to $27,720 (2024)
Medical Expenses	Deduction for eligible medical expenses	3% of net income

These deductions and credits can significantly reduce your taxable income and overall tax liability. The calculator does not automatically apply these - you must manually adjust your taxable income before calculating.

Example Calculation

Let's calculate the tax for a single Ontarian earning $60,000:

Subtract the Basic Personal Amount: $60,000 - $12,222 = $47,778 taxable income
Calculate tax for each bracket:
- $49,020 × 5.05% = $2,451.01
- Remaining $8,758 × 9.15% = $800.14
Total tax = $2,451.01 + $800.14 = $3,251.15

This example shows how the progressive tax system works. The first $49,020 is taxed at the lower rate, while the remaining income is taxed at the higher rate.
