Your SR&ED filing deadline
For a corporation, the SR&ED reporting deadline is generally 18 months after tax year-end. Enter the year-end to estimate the general date, then confirm it before filing.
Assumption: this calculator applies the general corporation rule of 18 months after tax year-end. Other taxpayer types have different deadlines.
Weekends and holidays: the CRA may treat the next business day as on time when a due date falls on a weekend or recognized public holiday. This tool shows the unadjusted general date, so confirm the filing date before relying on it.

How the deadline works
For a corporation, the SR&ED reporting deadline is generally 12 months after the T2 filing due date, which is usually 18 months after tax year-end. A December 31, 2024 year-end, for example, gives a June 30, 2026 reporting deadline. The prescribed information must be filed by that date, so plan the preparation work backward from it.
If the date falls on a weekend or public holiday recognized by the CRA, the next-business-day rule may apply. The calculator shows the unadjusted general date because recognized holidays can depend on the circumstances.
Preparing a claim in the last few weeks can make it harder to collect and review the records created while the work was underway. More on SR&ED deadlines
