Ontario Incorporation Tax Rates

Ontario's corporate tax rate is 12.25% of taxable income. This applies to both regular and small business incorporations. The tax is calculated on the business's net income after deducting eligible expenses.

Note: The corporate tax rate may change. Always verify with the latest government publications or consult a tax professional for current rates.

In addition to the corporate tax, businesses may also be subject to provincial sales tax (PST) on certain transactions.

Worked Examples

Example 1: Regular Incorporation

For a regular incorporation with a base fee of $300 and no additional fees:

Total Cost = $300 + $0 = $300
Tax Liability = $300 × 12.25% = $36.75

Your total incorporation cost would be $300, with an estimated tax liability of $36.75 in the first year.

Example 2: Small Business Incorporation

For a small business incorporation with a base fee of $100 and $50 in additional fees:

Total Cost = $100 + $50 = $150
Tax Liability = $150 × 12.25% = $18.38

Your total incorporation cost would be $150, with an estimated tax liability of $18.38 in the first year.
