The Scientific Research and Experimental Development tax incentive program remains one of Canada’s principal federal mechanisms for supporting private-sector research and development. In 2026, the Canada Revenue Agency also introduced an optional pre-claim approval process for eligible businesses seeking an early determination on planned work.
01 What SR&ED provides
The Canada Revenue Agency states that eligible claimants may receive two forms of tax support: a deduction against income and an investment tax credit. Eligibility is based on both the nature of the work and the expenditures associated with that work.
SR&ED is not a general innovation credit. The work must meet statutory and administrative requirements, and the claimant must be able to connect the eligible work to qualifying expenditures.
02 The core eligibility test
Current CRA guidance states that work must be conducted in Canada and must satisfy two central requirements: it must be undertaken for the advancement of scientific knowledge or for the purpose of achieving a technological advancement, and it must involve a systematic investigation or search carried out by experiment or analysis in a field of science or technology.
Routine engineering, standard practice, market research and commercial activity do not become SR&ED merely because they occur inside an innovative company. The relevant question is what scientific or technological uncertainty was addressed and how the work sought to resolve it.
03 Documentation should be contemporaneous
CRA guidance emphasizes supporting documentation. Organizations should maintain records that show the work performed, the uncertainties or hypotheses considered, the experiments or analyses conducted, the results obtained and the expenditures connected to the work.
Useful evidence can include technical notes, version histories, test results, design records, issue logs, project plans, time records and financial documentation. The objective is not to create a separate documentation system solely for tax purposes; it is to ensure that the normal engineering or scientific record can support the claim.
04 Preparing the claim
The CRA’s claim process requires organizations to identify eligible work, group that work into SR&ED projects, report the work and expenditures on Form T661, determine allowable and qualified expenditures and calculate the investment tax credit. Claimants must also respect the applicable reporting deadlines.
Organizations that receive other government funding for the same project should also review how that assistance affects the SR&ED expenditure and investment tax credit calculations.
05 Pre-claim approval introduced in 2026
As of April 1, 2026, the CRA offers an optional pre-claim approval process for eligible businesses. The process is intended to provide a determination on planned work before the business starts the work or incurs costs. CRA guidance identifies eligibility criteria for the applicant and project, including business-income and good-standing requirements.
The CRA states that it will provide a decision within eight weeks after a complete pre-claim approval application is submitted. The process includes a case number, an application form, supporting documents and, in many cases, a meeting with a CRA Research and Technology Advisor.
06 SR&ED as an operating discipline
For organizations with recurring research and development activity, SR&ED readiness is most effective when incorporated into project governance. Teams should establish project ownership, define the technical question at the start of work, maintain evidence through normal engineering workflows and periodically review whether the work continues to meet SR&ED requirements.
This reduces the risk that the organization attempts to reconstruct the technical narrative at year-end without sufficient evidence.
