Canadian Federal Ontario Tax Calculator 2018

Calculate your 2018 Canadian federal and Ontario tax liability with this professional tax calculator. The calculator uses the 2018 tax brackets and formulas to provide accurate results. You can input your taxable income and see how much you owe in federal and provincial taxes, as well as your effective tax rate.

How the 2018 Canadian Tax Calculator Works

The Canadian tax system is progressive, meaning higher income brackets are taxed at higher rates. The calculator applies both federal and Ontario tax rates to your taxable income. Here's how the calculation works:

Tax Calculation Formula

Federal Tax = Taxable Income × Federal Tax Rate
Ontario Tax = Taxable Income × Ontario Tax Rate
Total Tax = Federal Tax + Ontario Tax
Effective Tax Rate = (Total Tax / Taxable Income) × 100

The calculator uses the 2018 tax brackets and rates for both federal and Ontario taxes. It does not account for deductions, credits, or other tax adjustments. For a more precise calculation, consult a tax professional.
