If your business spends money solving technical problems, the SR&ED tax credit can return a large share of those costs as cash or tax savings. For Canadian-controlled private corporations (CCPCs), refunds can reach 35% of eligible R&D spending, while other corporations can still claim 15% non‑refundable credits. Recent federal budgets have changed key limits starting in 2025, which directly affects how much you can claim.
This guide focuses on current SR&ED tax credit rules, what changed for 2025–2026, and how to know if your work qualifies.
The Scientific Research and Experimental Development (SR&ED) Tax Incentive Program is a federal program administered by the Canada Revenue Agency (CRA). It rewards businesses that attempt technological advancement in Canada, even if the project fails.
Here’s how the SR&ED tax credit breaks down today:
35% refundable credit
15% non‑refundable credit
Budget 2025 confirmed that the SR&ED expenditure limit increased to $6 million, up from $3 million, for qualifying CCPCs.
This means:
Starting in 2025, the taxable capital phase‑out thresholds were adjusted to allow more mid‑sized CCPCs to access the enhanced 35% rate.
To claim the SR&ED tax credit, your work must aim to overcome scientific or technological uncertainty. Eligible costs usually include:
The work must be performed in Canada and documented properly. CRA looks for evidence of hypothesis testing, experimentation, and advancement—not routine engineering.
If you’re unsure whether your activities qualify, tools like GrantHub’s eligibility matcher can help you filter programs by industry, province, and R&D activity in seconds.
In addition to the federal SR&ED tax credit, many provinces offer their own credits that stack with the federal program.
Examples include:
These provincial programs can push total support well beyond 50% of eligible R&D costs in some cases. See our guide on SR&ED credits in Ontario for a province‑specific breakdown.
Claiming routine work
Software updates, standard debugging, or known processes usually do not qualify.
Weak documentation
CRA expects contemporaneous records. Recreating notes months later is a red flag.
Missing deadlines
SR&ED claims must be filed within 18 months of your tax year‑end.
Ignoring taxable capital limits
Even profitable CCPCs can still qualify after the 2025 changes—but only if thresholds are calculated correctly.
Q: Is the SR&ED tax credit refundable?
Yes, for CCPCs the enhanced 35% SR&ED tax credit is refundable, meaning you can receive cash even if your business has no taxes payable.
Q: Does my project have to succeed to qualify?
No. Failed experiments can still qualify as long as there was genuine technological uncertainty and systematic investigation.
Q: How much can my business claim under SR&ED?
For eligible CCPCs, up to $6 million in expenditures can earn a 35% refundable credit, or about $2.1 million per year.
Q: Can startups with no revenue claim SR&ED?
Yes. Many startups receive SR&ED refunds before becoming profitable, especially through payroll‑heavy R&D claims.
Q: Do I need an SR&ED consultant?
Not always. Smaller claims can be filed internally, but complex or high‑value claims may benefit from expert review. See SR&ED consultants for pros and cons.
The SR&ED tax credit remains one of the most generous R&D incentives in Canada—especially after the 2025 changes. Understanding the rates, limits, and documentation rules is key to maximizing your refund.
