If your business does R&D in Canada, you could be missing out on extra funding. Many companies use the federal SR&ED program but overlook provincial R&D tax credits that can be combined with the same work. With smart planning, you can claim both and increase your refund or tax savings—without increasing your R&D spending.
The Scientific Research and Experimental Development (SR&ED) Tax Incentive Program is Canada’s main federal R&D incentive, managed by the Canada Revenue Agency (CRA). It rewards businesses that perform eligible R&D in Canada.
Key facts:
SR&ED claims must be filed within 18 months of your corporate tax year-end.
Most provinces offer their own R&D tax credits that can be used alongside SR&ED. These are claimed through your provincial corporate tax return and usually rely on the same SR&ED-eligible expenditures.
Examples include:
Quebec offers several R&D-related tax credits, including refundable credits for salaries and contracts related to R&D done in the province. For example, the main refundable R&D salary tax credit rate is up to 30% for small and medium-sized businesses. Quebec’s rates are among the highest in Canada, making its programs especially valuable for eligible companies.
Important: Provincial programs do not replace SR&ED. They are designed to be used together.
“Stacking” means claiming both federal and provincial credits on the same eligible R&D project.
Here is how it typically works:
Identify eligible R&D activities
Determine which projects meet SR&ED criteria. This same technical work usually supports provincial claims.
Calculate eligible expenditures
Labour, materials, and other qualifying costs are calculated once.
Apply provincial credits first
Provincial R&D credits reduce the pool of expenditures used to calculate your federal SR&ED claim. This is required under tax rules.
Claim SR&ED on the adjusted amount
Calculate your federal SR&ED credit on the remaining eligible costs.
Even though provincial credits reduce the SR&ED base, the combined refund is almost always higher than claiming SR&ED alone.
GrantHub’s eligibility matcher can help you find R&D programs by province and business type, so you know which credits can be stacked.

Assuming SR&ED is “federal only”
Many businesses never check provincial programs and miss tens of thousands in refundable credits.
Double-counting expenses incorrectly
Provincial credits must be netted out before calculating SR&ED. Errors here can trigger reviews.
Missing the 18‑month SR&ED deadline
Late claims are denied automatically, even if the work qualifies.
Poor technical documentation
Financial numbers alone are not enough. You must show scientific or technological uncertainty and advancement.
Q: Can I claim SR&ED and provincial R&D tax credits on the same project?
Yes. Most provincial R&D credits are designed to stack with SR&ED, as long as the work is performed in that province.
Q: Do provincial credits reduce my SR&ED refund?
They reduce the expenditure base used for SR&ED, but the combined federal and provincial benefit is usually higher overall.
Q: Is SR&ED refundable for small businesses?
For many CCPCs, SR&ED credits are fully or partially refundable, even if no corporate tax is owed.
Q: Are R&D tax credits considered taxable income?
SR&ED and provincial credits generally reduce deductible R&D expenses, which can increase taxable income in future periods.
Q: What provinces offer R&D tax credits?
Ontario, Quebec, British Columbia, Alberta, and several other provinces have active R&D incentives. Availability and rates vary by province.
GrantHub tracks hundreds of active grant and tax credit programs across Canada—including federal and provincial R&D incentives—and shows which ones match your business profile.
SR&ED vs provincial R&D tax credits is not an either-or decision. The real value comes from stacking programs correctly and planning your claims early. If you want to see which federal and provincial R&D incentives apply to your business, GrantHub can help you identify opportunities based on your location, industry, and growth stage.
