Corporation Tax Rate

If you have incorporated your business, your company has to pay tax on corporation tax rate. Corporation taxes are taxes against profits earned by businesses during a given taxable period; they are generally applied to companies’ operating earnings, after expenses such as COGS, SG&A and depreciation have been deducted from revenues.

If your corporation is qualified as a Canadian Controlled Private Corporation (CCPC), the active income in your corporation will be eligible for the Small Business Deduction (SBD), which will bring your corporation tax rate as low as 15.5% in Ontario in 2013.

However, the government wants to discourage people from using corporations to defer tax on investment income. The investment income such as interest, dividends, rental income and royalty fee in a CCPC is subject to a high corporation tax rate of 46.17% in Ontario in 2013.
