As an Ontario business, if you are conducting investments or have expenses related to scientific research and experimental development (SRED) in a tax year, you may be eligible for the Ontario innovation tax credit. 

The Ontario innovation tax credit invites corporations to claim expenditures for SRED programing during a taxable year on their T2 corporate tax return.

The innovation tax claim is a calculation of 10% of associated expenses taken from the total amount of the tax year’s current expenditures and 40% of the corporation’s capital expenditures. This tax credit is given to eligible SRED programming of up to $2 million wherein all subsidiaries must share this amount.

Who is eligible for the Ontario innovation tax credit?

To be eligible to claim the Ontario innovation tax credit, your business must:

  • Be in operation at a permanent address in Ontario
  • Be a business that has conducted SRED within the tax year
  • Be a business which is eligible for a federal investment tax credit claim for qualified expenditures
  • Complete form T661
  • Not be exempt from any corporate income tax during the tax year
