Claimants are responsible for the information in their claim. Whether you prepare the claim yourself or it is done by someone else, check that your claim is complete, accurate, and supported by evidence before you submit it.

A complete SR&ED claim must include:

  • Form T661, SR&ED Expenditures Claim (current version)
  • Form T2SCH31 or Form T2038(IND) to claim an ITC
  • Other forms, as needed (T1145, T1146, T1174, T1263, and any attachments)

To learn more about prescribed SR&ED forms, review Section 3, SR&ED Filing Requirements Policy.
