Many Canadian businesses claim SR&ED but miss out on provincial R&D tax credits. The good news is that federal and provincial programs are designed to work together. If your company does R&D in British Columbia, you can often claim both SR&ED and the BC Scientific Research & Experimental Development Tax Credit on the same project, as long as you follow the stacking rules.
The Scientific Research & Experimental Development (SR&ED) program is a federal tax incentive administered by the CRA. It supports eligible R&D work done in Canada through refundable or non-refundable tax credits. Provinces offer their own credits based on SR&ED rules, using similar definitions of eligible work and costs.
Here’s the key idea:
You don’t choose between federal and provincial R&D credits. You usually claim both.
Provincial credits are calculated after federal SR&ED rules are applied and usually reduce the SR&ED expenditure pool to prevent claiming the same expenses twice.
If your R&D is performed in British Columbia, the BC Scientific Research & Experimental Development Tax Credit is the main provincial program to combine with SR&ED.
This credit is claimed on your T2 corporate tax return, alongside your federal SR&ED claim.
Here’s how most businesses combine SR&ED with provincial R&D tax credits:
Identify eligible SR&ED work
Use CRA’s definition of scientific or technological uncertainty, advancement, and systematic investigation.
Calculate federal SR&ED expenditures first
This includes eligible wages, materials, and contracts under CRA rules.
Apply the provincial credit
File both claims together
Federal and provincial credits are claimed through your corporate tax return and related schedules.
Tools like GrantHub’s eligibility matcher can help you quickly check which provincial R&D credits apply based on where your work is done and your corporation type.
While this article focuses on BC, the same stacking concept applies in other provinces:
Ontario Business Research Institute Tax Credit
Innovation and Development Labour Rebate Program (PEI)
Each province has different rates, refundability rules, and caps. Always check how provincial assistance affects your federal SR&ED pool.
Assuming you must choose one program
SR&ED and provincial R&D credits are meant to be combined, not treated as alternatives.
Forgetting expenditure adjustments
Provincial credits usually reduce your SR&ED expenditure pool. Missing this can trigger CRA reviews.
Claiming the wrong province
Credits are based on where the R&D work is physically performed, not where your head office is.
Missing refundability limits
In BC, only CCPCs qualify for the refundable portion of the credit.
Q: Can I claim SR&ED and the BC SR&ED tax credit on the same project?
Yes. If the R&D work is performed in British Columbia and meets SR&ED criteria, you can usually claim both federal SR&ED and the BC SR&ED tax credit.
Q: Does the provincial credit reduce my federal SR&ED refund?
Yes. Provincial assistance typically reduces the SR&ED expenditure pool to prevent claiming the same expenses twice, but you still benefit overall.
Q: Is the BC SR&ED tax credit refundable for all companies?
No. Refundability is generally limited to Canadian-controlled private corporations, with a cap tied to qualifying expenditures.
Q: What if my R&D spans multiple provinces?
You may need to allocate expenditures by province and claim the appropriate provincial credits separately, based on where the work occurred.
Q: Do grants affect SR&ED claims the same way as tax credits?
Yes. Most government assistance, including grants, must be deducted from eligible SR&ED expenditures.
GrantHub tracks hundreds of active grant and tax credit programs across Canada—including federal and provincial R&D incentives—so you can quickly see which ones match your business profile.
If you’re already claiming SR&ED, the next step is to check which provincial R&D tax credits you qualify for—and how they interact. GrantHub helps you compare programs by province, business type, and R&D activity, so you can claim every dollar you’re eligible for without guesswork.
