Many Canadian businesses assume SR&ED is only for labs or biotech. That’s not true. As of 2026, SR&ED eligibility still hinges on what problem you were trying to solve and how you approached it, not your industry. With recent federal changes raising the enhanced credit limit to $6 million, understanding eligibility matters more than ever.
Below is a clear, up‑to‑date breakdown of how CRA decides if your work qualifies — and where businesses most often get it wrong.
CRA uses a three-part eligibility test. All three must be met for your project to qualify for SR&ED tax credits.
Your project must attempt to overcome a problem where the solution was not already known or readily available to a competent professional.
Examples:
Routine work does not qualify. That includes debugging with known fixes or applying standard methods.
CRA expects evidence of a structured approach, similar to the scientific method.
This usually includes:
You do not need lab coats or white papers. Internal test logs, Git commits, design notes, and experiment results often meet this requirement.
The goal must be to advance knowledge beyond your company, not just improve efficiency or aesthetics.
Qualifying advancement:
Non-qualifying work:
CRA is clear about exclusions, even if the work was expensive or time-consuming.
Excluded activities include:
If your project shifted into production after solving the uncertainty, only the experimental phase is eligible.
Eligibility determines what work qualifies. Your corporate structure determines how much you get back.
For Canadian‑Controlled Private Corporations (CCPCs):
These changes apply to taxation years beginning on or after December 16, 2024.
Other corporations:
Capital expenditures (like certain equipment) are also eligible again under the restored rules.
If your project qualifies federally, it often unlocks provincial SR&ED credits too.
Examples:
CRA eligibility is the foundation. Provinces build on it.
Describing business problems instead of technical ones
CRA cares about technological uncertainty, not missed deadlines or customer needs.
Claiming routine development as SR&ED
Using known frameworks or standard methods usually fails eligibility review.
No documentation during the year
Recreated narratives after year-end are weak. Contemporaneous records matter.
Assuming software always qualifies
Software can qualify — but only when it advances technology, not just features.
Q: Is my software project eligible for SR&ED?
Possibly. Software qualifies when it attempts to overcome technological uncertainty and achieve advancement, not when it involves routine coding or feature development.
Q: Do startups need revenue to qualify?
No. Pre‑revenue companies can still be eligible and receive refundable SR&ED credits if they meet the criteria.
Q: Can failed projects qualify?
Yes. Failure does not disqualify a claim if systematic experimentation was performed.
Q: How long do I have to file an SR&ED claim?
Most corporations have 18 months after their tax year‑end to file Form T661.
Q: Does using contractors affect eligibility?
No, but only eligible portions of contractor work can be claimed, and documentation is critical.

SR&ED eligibility is about how you solve technical problems, not how innovative your product sounds. With higher credit limits now in effect, eligibility mistakes can cost real money.
