Key Takeaway
Canadian businesses can claim SR&ED credits at both the federal and provincial level simultaneously, with combined rates that can recover 40–65% of eligible R&D wages depending on province and company type.
Most companies know about the federal SR&ED tax credit. Fewer realize every major province runs its own parallel program on top of it. If you’re only claiming federally, you’re leaving money on the table.
This guide covers what each province offers, how provincial credits stack with the federal credit, and the numbers you need for financial planning.
How do federal and provincial SR&ED credits work together?
They’re independent claims on the same expenditures. You file the T661 with CRA for the federal credit, and a separate provincial form for the provincial credit. Both reference the same qualifying R&D work. There’s no coordination required beyond ensuring the expenses are properly documented.
The federal credit is the foundation. For Canadian-controlled private corporations (CCPCs), the federal program offers a 35% refundable investment tax credit on the first $3M of qualified SR&ED expenditures annually. Above that threshold, the rate drops to 15% non-refundable. Other corporations get 15% non-refundable.
Provincial credits layer on top. Depending on your province, this adds anywhere from 10% to 30% more recovery on the same wages and materials.
What does Alberta offer for SR&ED?
Alberta’s SR&ED tax credit is 20% refundable on eligible R&D expenditures, up to $4M in annual qualifying costs. The program is administered provincially and applies to wages paid to employees conducting qualifying work in Alberta.
For a CCPC spending $1M on qualifying R&D in Alberta: the federal credit returns $350K (35%), the provincial credit returns $200K (20%). Combined recovery: 55% of that $1M.
Alberta’s 20% rate is among the most generous in Canada. The program is particularly useful for energy-sector R&D, though it applies across all industries.
What does British Columbia offer for SR&ED?
BC’s refundable SR&ED tax credit sits at 10% for most corporations. The credit applies to qualifying wages for R&D conducted in BC and is refundable, meaning BC companies receive it as cash even in a loss year.
BC has historically capped its program at the first $3M in qualified expenditures. Combined with the federal CCPC rate, a company doing $1M of qualifying work in BC recovers 45% (35% federal + 10% provincial).
What does Ontario offer for SR&ED?
Ontario runs two programs simultaneously.
Ontario Research and Development Tax Credit (ORDTC): 10% non-refundable credit on qualifying R&D expenditures. Available to all corporations with a permanent establishment in Ontario.
Ontario Innovation Tax Credit (OITC): 20% refundable credit for small- and medium-sized businesses (annual revenue under $20M, assets under $50M). The refundable rate makes this the more impactful program for qualifying companies.
The distinction matters. If your company qualifies for the OITC, you’re looking at 55% combined recovery (35% federal + 20% OITC). If you only qualify for the ORDTC, you’re at 45%, and only 35% of it is cash-in-hand.
What does Quebec offer for SR&ED?
Quebec’s RS&DE (the French equivalent program, Recherches scientifiques et développement expérimental) is the most generous provincial program in Canada.
The base refundable rate is 30% on qualifying wages paid to employees conducting eligible work in Quebec. For SMEs — companies with assets below $50M — the rate can reach 30% on the first $3M in qualifying wages.
Quebec also runs a separate refundable credit for R&D subcontracts, at a lower rate (14–27% depending on company size and the nature of the subcontract).
For a CCPC operating in Quebec, combined federal and provincial recovery can reach 65% on qualifying wages. This makes Quebec one of the best jurisdictions in the world for R&D-heavy software and biotech companies.
What do Manitoba, Nova Scotia, and New Brunswick offer?
Manitoba: 15% refundable credit on qualifying SR&ED wages, up to specific annual limits. The Manitoba SR&ED Tax Credit applies to qualified expenditures incurred by corporations with a permanent establishment in Manitoba.
Nova Scotia: 15% refundable credit on qualifying wages and overhead. Straightforward provincial stacking on top of the federal program.
New Brunswick: 15% refundable credit on eligible SR&ED expenditures. Like Nova Scotia, it stacks directly on the federal credit without significant additional complexity.
For CCPCs in these three provinces, the combined federal + provincial recovery rate lands at 50% on qualifying wages within the federal $3M threshold.
How do you calculate your combined SR&ED credit?
Start with your total qualifying expenditures for the fiscal year. For each dollar of qualifying wages:
- Apply the federal rate (35% for CCPC under threshold, 15% above)
- Apply your province’s rate against the same expenditures
- Sum both for your total credit
Example: A Montreal CCPC with $500K in qualifying wages.
- Federal credit: $500K × 35% = $175K (refundable)
- Quebec RS&DE: $500K × 30% = $150K (refundable)
- Total recovery: $325K (65% of qualified wages)
That $325K comes back as cash — you don’t need taxable income to receive it.
The calculation gets more involved when you layer in overhead using the proxy method, subcontractor costs, and capital expenditures. A SR&ED consultant or software like Chrono R&D handles the calculation automatically once your project data is captured.
How do you manage cash flow while waiting for SR&ED credits?
The main frustration with SR&ED isn’t the program — it’s the timing. You spend the money in year one, file the claim in year two, and receive the credit months after filing. For fast-growing companies, that gap creates real cash pressure.
SR&ED financing bridges it. Several lenders specialize in advancing SR&ED credits — typically 70–80% of the expected credit, at rates between 1–2% per month. The advance is repaid when CRA releases the funds.
It’s not free money, but for companies where R&D spending is high relative to cash reserves, financing the SR&ED receivable can free up capital for hiring or infrastructure that would otherwise wait.
The other strategy: file on time and file well. CRA’s standard processing window is 60–180 days after filing. An incomplete T661 or a claim that triggers review extends this significantly. Thorough documentation up front means faster processing.
What’s the application process for claiming both credits?
The federal and provincial claims are filed together with your corporate tax return.
- Federal: Complete Form T661 (SR&ED expenditures and project descriptions) and Schedule 31 (investment tax credit calculation). Submit with your T2 return.
- Provincial: Each province has its own form. Quebec uses the CO-1029.8.36.II, Ontario uses the CT23 (ORDTC) and the OITC schedule, Alberta and BC have their own provincial forms.
Your tax accountant handles the provincial filing. The SR&ED-specific work — project narratives, eligible activity identification, expenditure allocation — is where a dedicated consultant or SR&ED software adds the most value.
The 18-month deadline is firm. Claims must be filed within 18 months of your fiscal year-end. Miss it and the claim is gone.
Frequently Asked Questions
Can I claim both the federal and provincial SR&ED credit on the same expenses?
Yes. Federal and provincial SR&ED programs are independent. The same qualifying wages and eligible expenditures can generate credits in both programs. There’s no double-dipping restriction — the two levels of government each fund their own incentive.
What if my company operates in multiple provinces?
You claim the provincial credit in each province where you have a permanent establishment and where the qualifying work was conducted. If your team is split between Ontario and Quebec, you allocate wages by province and claim the applicable provincial credit for each portion.
Does a failed R&D project still qualify?
Yes. SR&ED eligibility is based on whether the work involved systematic investigation into technological uncertainty — not whether it succeeded. A failed attempt that produced new knowledge still qualifies. Document what you tried, what you observed, and what you concluded.
