What is the deadline to file your SR&ED claim?

The deadline to file your SR&ED claim is the day that is 12 months after the filing due date of the income tax return for the year.

This means that corporations have 18 months, and individuals have 17.5 months, from the end of the tax year in which the expenditures were incurred to file an SR&ED claim.

A corporation exempt from tax that incurs SR&ED expenditures has to file Form T661 on or before the due date for filing its return for income for the year or it will be subject to a penalty. The filing due date is six months after the corporation’s tax year.
