Calculating corporate income tax in Ontario involves several steps. First, determine your taxable income by subtracting allowable deductions from your total revenue. Then apply the appropriate tax rates to your taxable income. The Ontario government offers several tax credits and deductions that can reduce your taxable income.

Steps to Calculate Corporate Income Tax

1. Calculate your total revenue from all sources.
2. Subtract allowable business expenses to determine taxable income.
3. Apply the Ontario corporate tax rates to your taxable income.
4. Subtract any applicable tax credits to determine your final tax liability.

Formula for Corporate Income Tax

The formula for calculating corporate income tax in Ontario is straightforward. You multiply your taxable income by the applicable tax rate to determine your tax liability.

Where:

• Taxable Income = Total Revenue - Allowable Expenses - Tax Credits
• Tax Rate = Applicable Ontario corporate tax rate (12% to 26.5%)

The Ontario government provides a progressive tax system, meaning higher income levels are taxed at higher rates. The tax rates are as follows:

• 12% on the first $50,000 of taxable income
• 14% on the next $50,000 of taxable income
• 16.5% on the next $50,000 of taxable income
• 19% on the next $50,000 of taxable income
• 20.5% on the next $50,000 of taxable income
• 22.5% on the next $50,000 of taxable income
• 26.5% on taxable income over $300,000

Worked Example

Let's walk through a worked example to illustrate how to calculate corporate income tax in Ontario. Suppose a corporation has a total revenue of $400,000 and allowable expenses of $250,000.

Step 1: Calculate Taxable Income

Taxable Income = Total Revenue - Allowable Expenses

Taxable Income = $400,000 - $250,000 = $150,000

Step 2: Apply Tax Rates

The Ontario corporate tax rates are progressive, so we apply them to the taxable income:

• $50,000 × 12% = $6,000
• $50,000 × 14% = $7,000
• $50,000 × 16.5% = $8,250
• Remaining $0 × 19% = $0

Total Corporate Income Tax = $6,000 + $7,000 + $8,250 = $21,250
