Corporate tax returns
Under the Income Tax Act, all corporations have to file a T2 corporation tax return, even if there is no tax payable. This includes non-profit organizations, tax-exempt corporations and inactive corporations. The only exception to this rule is a corporation that was a registered charity throughout the year. Corporate income tax eturns are due six months after the fiscal year end. For corporations claiming the small business deduction, the balance of the corporation tax payable is due on the last day of the third following month.
