SR&ED Tax Credit Canada: How Much You'll Actually Get Back

What SR&ED actually is

SR&ED is a tax credit you claim after doing eligible R&D, not a grant you apply for in advance, and it pays out even at 0% ownership stake in the outcome's success.

SR&ED rewards genuine scientific and engineering investigation, not general product development. Building a new app with known frameworks is commercial innovation; solving a problem where the solution approach was unknown, running experiments, and documenting the results as you go, is SR&ED. The distinction matters because CRA's biggest single rejection reason is claiming routine engineering as research: 90% of claims are accepted as filed, but the 10% that are reduced or denied almost always fail on this line.

Federal and provincial rates

CCPCs get 35% refundable on the first $6 million; everyone else gets 15%; five provinces layer 8% to 30% on top.

Company type is the single biggest lever in your SR&ED credit. A CCPC, a Canadian-controlled private corporation, is a private company controlled by Canadian residents and not listed on any stock exchange. A CCPC gets the enhanced 35% rate on the first $6,000,000 of its qualified expenditure pool (doubled from $3,000,000 by Budget 2025), fully refundable as cash even with no tax owing, capped at $2,100,000 a year. A non-CCPC gets 15% on the whole pool, and it is generally non-refundable, meaning it only reduces tax already owed. For an eligible CCPC, SR&ED is a Stack Floor program. The Stack Floor is the funding a qualified applicant can count on before any competitive program: entitlement-style tax credits and guaranteed-access financing that pay every eligible claim. If the work qualifies, the credit pays.

Five provinces run their own R&D tax credit alongside federal SR&ED: Ontario's OITC and ORDTC (8% plus 3.5%), Quebec's CRIC (20% to 30%), Manitoba's R&D Tax Credit (15%), Saskatchewan's R&D Tax Credit (10%), and Alberta's Innovation Employment Grant (8% to 20%). Stacking matters: a CCPC in Ontario can recover close to 46.5% of eligible R&D spending once federal and provincial credits combine, and Quebec's higher SME rate pushes the combined recovery to roughly 65%. The Prescribed Proxy Amount adds a flat 55% of qualifying salaries as deemed overhead, with no receipts required, before any provincial rate is even applied.

Should you file an SR&ED claim?

If a CCPC has $200,000 or more in eligible R&D spend, filing is almost always worth it, even after consultant fees.

• You built something new using known technologies: likely not eligible. Commercial innovation with an established framework is not the same as resolving a technological uncertainty.
• You attempted something where the technical approach was uncertain: likely eligible. Document the hypotheses, the experiments, and the results as you go.
• You spent under $50,000 on R&D this year: weigh the cost-benefit. At 35%, a $50,000 claim yields about $17,500; after a 15% to 25% consultant fee, you keep roughly $13,000 to $15,000.
• You are a CCPC with $200,000 or more in eligible R&D expenses: strong candidate. That level yields $70,000 or more in refundable credits at the enhanced rate, comfortably worth a contingency-fee consultant for a first claim.
• You are a non-CCPC or foreign-controlled company: still eligible at the 15% basic rate. The credit is generally non-refundable but carries forward 20 years, so file to build a balance for when you become profitable.

SR&ED does not require taxable income, which is the single most common thing pre-revenue founders get wrong. A pre-revenue CCPC spending $200,000 on eligible R&D can receive roughly $70,000 in cash from CRA even while it owes zero corporate tax, because the enhanced rate is fully refundable, not just a deduction against tax owed. The eligibility bar is identical to any other claimant: genuine technological uncertainty, systematic investigation, and contemporaneous documentation. Because SR&ED is a Stack Floor program rather than a competitive grant, eligibility rests entirely on the technical work itself, not on revenue, headcount, or how many other companies applied in the same year.

Stacking SR&ED with IRAP and other programs

IRAP and SR&ED are designed to complement each other, but IRAP funding reduces your SR&ED-eligible pool dollar for dollar.

NRC IRAP covers a share of eligible R&D labour costs as a non-repayable contribution, typically $75,000 to $1,000,000 with a $10,000,000 ceiling on major capital projects. You then claim SR&ED only on the portion you paid out of pocket, since IRAP funding counts as government assistance and must be deducted from your expenditure pool first. If a $500,000 project gets $400,000 from IRAP, you claim SR&ED on the remaining $100,000; at the enhanced 35% rate, that yields $35,000, for a combined $435,000 of government support on a $500,000 project. The two programs are explicitly designed to work together, not compete: IRAP funds the project going in, SR&ED pays out on the residual once the year closes.

Federal and provincial R&D credits stack automatically, with no separate application. You file the federal SR&ED claim with CRA and the provincial claim with your provincial tax return, both on the same eligible expenditures. An Ontario CCPC with $400,000 in eligible R&D receives roughly $140,000 federal (35%) plus $32,000 OITC (8%) plus $14,000 ORDTC (3.5%), for $186,000 total. A Quebec CCPC of similar size can push the combined rate to around 65% once the CRIC's higher SME rate applies.

Filing, common mistakes, and a worked example

File within 18 months of fiscal year-end with no exceptions; the technical narrative in Form T661 Part 2 decides most claims, not the arithmetic.

1. Identify eligible projects during the year. Ask whether a competent professional could solve the problem with standard practice. If yes, it is not SR&ED.
2. Document contemporaneously. Project logs, test results, and meeting minutes written as the work happens, not reconstructed later.
3. Track eligible expenditures separately. Salaries, materials, 80% of arm's-length subcontractor payments, and capital equipment for R&D use, using either the 55% proxy overhead method or actual costs.
4. Write the Form T661 Part 2 narrative. Describe the technological uncertainty, the systematic investigation, and the advancement achieved, in technical rather than marketing language.
5. Calculate and file. Schedule T2SCH31 for corporations, or Form T2038(IND) for individuals, with your T2 or T1 return.
6. Handle any CRA review. Financial reviews check the numbers; technical reviews check the science. Respond promptly to keep processing on track.

CRA reviews a claim in one of two ways: a financial review, checking whether the expenditure calculations are correct, or a technical review, evaluating whether the work meets the three-part SR&ED test. Many claims get both. First-time filers and unusually large claims are reviewed more often than routine, well-documented repeat claims. The biggest single trigger is after-the-fact documentation, timesheets and technical notes written weeks or months after the work happened. A claim built on contemporaneous project logs moves through review faster and survives technical scrutiny more often than one reconstructed from memory at filing time. Respond to every CRA request promptly; delays can stretch processing from the standard 60 to 120 days out to 6 to 12 months.

Worked example: an Ontario CCPC's claim

A 12-person Toronto SaaS company spent a fiscal year building a document-analysis pipeline whose accuracy target existing open-source models could not reliably hit, a genuine technological uncertainty. Eligible expenditures: $320,000 in salaries, $15,000 in materials, $24,000 in subcontractor costs (80% eligible), and $176,000 in proxy overhead (55% of salaries), for a $535,000 pool. The federal enhanced ITC at 35% comes to $187,250; Ontario's OITC adds $42,800 (8%), and the ORDTC adds $18,725 (3.5%, non-refundable). After a 20% consultant contingency fee on the refundable portion, the company's net cash refund was $184,040, filed five months after year-end, well inside the 18-month window, and processed by CRA in 85 days. That figure sits well above what an early-stage company typically sees, though; for the honest range, see what a typical SR&ED refund looks like for a small startup.

Mistakes that shrink or kill claims

• Claiming routine engineering as R&D: the number one rejection reason. Novel products built with known technologies are not technological uncertainty.
• Writing the T661 narrative after the fact: retroactive descriptions read differently from contemporaneous logs, and reviewers can tell.
• Poor time tracking between R&D and non-R&D: undocumented time-allocation estimates are the fastest way to get a claim reduced.
• Not reducing the expenditure pool for government assistance: IRAP and provincial grants must be subtracted before you calculate the SR&ED credit.
• Confusing commercial risk with technological uncertainty: "will customers buy it" is commercial risk; "can the algorithm process 10M records under 200ms" is technological uncertainty.
