If your business spends money trying to solve technical problems or build new products, the SR&ED tax program could refund a large portion of those costs. The Scientific Research and Experimental Development (SR&ED) tax incentive is Canada’s largest federal R&D program, delivering over $3 billion each year to Canadian businesses through tax credits.
This guide explains what the SR&ED tax is, how much you can claim in 2025–2026, and what counts as eligible work—without getting buried in forms or jargon.
The SR&ED tax refers to federal (and provincial) tax credits available when your business performs eligible research and development in Canada. The program is administered by the Canada Revenue Agency (CRA) and applies across industries, not just tech.
At a high level, SR&ED rewards you for:
You do not need to succeed. Failed experiments can still qualify.
For a plain‑language overview, see What is SR&ED?.
The value of the SR&ED tax depends on your business size and structure.
For Canadian‑Controlled Private Corporations (CCPCs):
For non‑CCPCs and public companies:
Your access to the 35% refundable rate phases out if:
The enhanced rate is fully phased out at $800,000 taxable income or $50 million taxable capital.
Eligible SR&ED expenditures must be directly related to qualifying R&D work performed in Canada.
Common claimable costs include:
Capital expenditures remain excluded following earlier reforms, and no major changes were made to eligible cost categories in Budget 2024.
The CRA recognizes three types of SR&ED activities:
Experimental development
Improving products, processes, or software through technical experimentation
Applied research
Advancing knowledge with a practical objective
Basic research
Advancing scientific knowledge without a specific commercial goal
Routine engineering, debugging, or market research does not qualify unless it addresses genuine technological uncertainty.
Examples by industry are covered in SR&ED examples.
Many provinces offer stackable SR&ED tax credits, increasing your total refund.
For example:
Other provinces, including Ontario and Quebec, have their own SR&ED‑linked incentives. See SR&ED credits Ontario for a provincial breakdown.
Tools like GrantHub’s eligibility matcher can help you filter programs by province and industry in seconds, including SR&ED and complementary funding.
You claim the SR&ED tax credit as part of your corporate tax return:
Missing the deadline means losing the credit entirely.
A step‑by‑step breakdown lives in our existing guide, so this page focuses on understanding the SR&ED tax—not duplicating filing instructions.
Assuming your work must succeed
SR&ED rewards experimentation, not commercial success.
Claiming routine work
Standard coding, testing, or customization usually fails CRA reviews.
Weak technical documentation
The CRA looks for evidence of uncertainty, hypotheses, and results.
Missing the 18‑month deadline
Late SR&ED claims are automatically denied.
Q: Is the SR&ED tax credit refundable?
Yes, for most CCPCs. The 35% federal SR&ED credit is refundable up to the expenditure limit, meaning you can receive cash even if you owe no tax.
Q: Can startups with no revenue claim SR&ED tax credits?
Yes. Pre‑revenue startups can receive refundable SR&ED credits if they qualify as CCPCs.
Q: Does software development qualify for SR&ED?
Sometimes. Software work must address technological uncertainty and go beyond routine development to qualify.
Q: Has Budget 2024 changed SR&ED?
No major structural changes were made. The core rates, thresholds, and eligibility rules remain in place for 2025–2026.
Q: Can SR&ED be combined with other grants?
Yes, but other government funding may reduce eligible SR&ED expenditures. This is called “assistance stacking.”
GrantHub tracks 2,500+ active grant programs across Canada — check which ones match your business profile to see how SR&ED fits into your full funding mix.
The SR&ED tax can return tens or hundreds of thousands of dollars to eligible Canadian businesses—but only if you understand how the rules apply to your work. Before you file, it helps to see SR&ED alongside other federal and provincial incentives.
GrantHub helps you do that by mapping SR&ED, provincial credits, and non‑dilutive grants in one place, so you can plan funding with confidence instead of guessing.
