Ontario Tax Brackets 2017 Calculator

Calculate your Ontario tax liability for 2017 using this official tax bracket calculator. Understand federal and provincial tax rates, deductions, and credits to accurately determine your tax obligations.

How Ontario Tax Brackets Work in 2017

In 2017, Ontario implemented a progressive tax system where your tax rate increases as your income rises. The tax brackets for Ontario residents in 2017 were as follows:

Note: These rates apply to Ontario residents only. Federal tax rates are calculated separately and added to the provincial tax.

Taxable Income	Marginal Rate
$0 - $43,906	5.05%
$43,907 - $87,813	9.15%
$87,814 - $150,000	11.16%
$150,001 - $220,000	12.16%
Over $220,000	13.16%

The tax is calculated by applying the marginal rate to the amount of income that falls within each bracket. For example, if you earn $50,000, the first $43,906 is taxed at 5.05%, and the remaining $6,094 is taxed at 9.15%.

Federal vs. Provincial Tax Rates

In addition to Ontario's provincial tax rates, federal tax rates also apply. The federal tax brackets for 2017 were:

Taxable Income	Marginal Rate
$0 - $45,282	15%
$45,283 - $90,563	20.5%
$90,564 - $140,388	26%
$140,389 - $200,000	29%
Over $200,000	33%

The total tax liability is the sum of the provincial and federal taxes. For example, a $50,000 income would be taxed at 5.05% + 15% = 20.05% in the first bracket.

Deductions and Tax Credits

Several deductions and tax credits can reduce your taxable income and lower your tax bill. Common deductions include:

RRSP contributions (up to a certain limit)
Medical expenses (over 3% of income)
Donations to registered charities
Home office expenses
Moving expenses (for certain individuals)

Tax credits directly reduce your tax liability. Examples include:

Canada Child Benefit
Canada Pension Plan contributions
Employment Insurance premiums
Provincial tax credits (varies by province)

These deductions and credits can significantly impact your final tax liability, so it's important to account for them in your calculations.

Example Calculation

Let's calculate the tax for a single Ontario resident earning $50,000 in 2017.

Provincial Tax: $43,906 × 5.05% = $2,212.73 ($50,000 - $43,906) × 9.15% = $6,094.25 Total Provincial Tax = $2,212.73 + $6,094.25 = $8,306.98 Federal Tax: $45,282 × 15% = $6,792.30 ($50,000 - $45,282) × 20.5% = $967.70 Total Federal Tax = $6,792.30 + $967.70 = $7,760.00 Total Tax = $8,306.98 + $7,760.00 = $16,066.98

After accounting for deductions and credits, your final tax liability would be less. For example, if you have $5,000 in eligible deductions, your tax liability would be $11,066.98.
