What Is the SR&ED Program?
The Scientific Research and Experimental Development (SR&ED) program is Canada’s largest federal tax incentive — delivering over $4 billion annually to businesses conducting qualifying research and development. Administered by the CRA, SR&ED lets Canadian companies recover up to 43% of eligible R&D expenditures through refundable and non-refundable investment tax credits (ITCs).
SR&ED claims Canada is available to CCPCs, public corporations, individuals, and partnerships. For Mississauga businesses in technology, manufacturing, engineering, and life sciences, SR&ED can be one of the most significant cash injections your company receives in a year.

SR&ED Tax Credit Rates 2025: How Much Can You Get Back?
| Business Type | Federal SR&ED ITC | Ontario OITC/ORDTC | Combined Rate | Refundable? |
|---|---|---|---|---|
| CCPC — first $3M of qualified expenditures | 35% | 8% OITC | Up to 43% | ✅ Yes — cash refund |
| CCPC — above $3M threshold | 15% | 3.5% ORDTC | Up to 18.5% | ❌ Non-refundable (reduces tax) |
| Other Canadian corporations | 15% | 3.5% ORDTC | Up to 18.5% | ❌ Non-refundable |
| Individuals / partnerships | 15% | Varies by province | Up to 18.5% | ❌ Non-refundable |
Ontario CCPC Example: A Mississauga tech company spends $500,000 on qualifying SR&ED work:
- Federal 35% ITC: $500,000 × 35% = $175,000 cash refund
- Ontario OITC 8%: $500,000 × 8% = $40,000 additional
- Total recovered: $215,000 — effective R&D cost reduced to $285,000
What Qualifies as SR&ED? The Three-Part Test
The CRA applies a strict three-part test. All three must be satisfied:
- Scientific or technological advancement: The work must attempt to advance knowledge beyond what is currently known — not merely applying existing techniques in a new context
- Scientific or technological uncertainty: A genuine uncertainty that qualified professionals could not resolve without systematic investigation
- Scientific or technological content: A systematic investigation using the scientific method — hypothesis, experiment, analysis, conclusion
| ✅ Qualifies for SR&ED | ❌ Does NOT Qualify |
|---|---|
| Novel software algorithms where standard approaches fail | Routine software development and bug fixes |
| Engineering processes that exceed current technical capability | Applying standard engineering practices |
| Biotech, pharma, or medical device research | Quality control and routine testing |
| Prototyping with genuinely uncertain technical outcomes | Social science, humanities, or market research |
| Manufacturing process innovations beyond current industry standards | Style changes or aesthetic improvements |
| AI/ML model architecture when existing frameworks are insufficient | Data collection without experimental design |
Eligible SR&ED Expenditures: What You Can Claim
| Expenditure Category | Eligible? | Key Rules |
|---|---|---|
| Salaries — directly engaged in SR&ED | ✅ 100% | Must document time allocation; time sheets strongly recommended |
| Salaries — supporting SR&ED work | ✅ 55% (proxy) or actual | Project managers, HR, admin supporting SR&ED staff |
| Materials consumed or transformed | ✅ 100% | Raw materials used directly in experiments |
| Third-party Canadian contracts | ✅ 80% | Arm’s-length Canadian contractors only; 100% for prescribed contracts |
| Overhead — proxy method | ✅ 55% of SR&ED labour | Simplest option; most CCPCs choose this |
| Overhead — traditional method | ✅ Actual costs | More paperwork; beneficial if overhead is high relative to labour |
| Capital equipment | ⚠️ Limited ITC only | No deduction; ITC credit only; phased out for many expenditures |
| Non-arm’s length payments | ⚠️ At cost only | Payments to related parties capped at their actual cost to produce |
How to File an SR&ED Claim: Step-by-Step
- Identify qualifying projects during the year — do not wait until year-end. Keep contemporaneous documentation as the work happens: lab notebooks, experiment logs, test results, version control commits
- Track employee time allocation — maintain time records showing what percentage of each person’s time was spent on SR&ED vs non-SR&ED activities. Weekly time sheets are the CRA’s preferred format
- Complete Form T661 (SR&ED Expenditures Claim) — describes each qualifying project with technical narrative (the “uncertainty and advancement” story) and financial details
- Calculate ITCs on Schedule T2SCH31 (corporations) or Form T2038 (individuals)
- File with your T2 corporate tax return — SR&ED claims must be filed within 18 months of fiscal year end. This deadline is absolute and non-extendable
- Claim Ontario provincial credits separately — OITC (8% refundable) and ORDTC (3.5% non-refundable) are claimed on Schedule T2SCH508
The 18-Month SR&ED Deadline: Non-Negotiable
The 18-month filing deadline for SR&ED is the most critical rule to know. There are no extensions — not for late accountants, not for CRA delays, not for any reason. A claim filed one day late is permanently disallowed.
- Fiscal year ending December 31, 2024 → SR&ED claim due by June 30, 2026
- Fiscal year ending March 31, 2025 → SR&ED claim due by September 30, 2026
- Fiscal year ending June 30, 2025 → SR&ED claim due by December 31, 2026
Surviving a CRA SR&ED Technical Review
The CRA reviews a significant percentage of SR&ED claims — especially first-time claimants and large claims. A Research and Technology Advisor (RTA) assesses whether your work meets the three-part test:
- What they review: Your technical project descriptions in Form T661, supporting documentation, and may conduct a site visit or technical interview
- What gets claims denied: Vague technical narratives, no contemporaneous documentation, inability to articulate the “uncertainty” clearly, or routine work described as experimental
- What protects your claim: Detailed lab notebooks, experiment logs dated during the project, clear articulation of the technological uncertainty and how you tested hypotheses, strong technical narrative written by someone who did the work
SR&ED for Startups: Getting Cash Back Before Profitability
One of SR&ED’s most powerful features: a CCPC in its early years with no taxable income can still receive the fully refundable 35% ITC on eligible expenditures up to $3 million. This means:
- Startup spends $300,000 on qualifying R&D in Year 1
- Federal SR&ED refund: $300,000 × 35% = $105,000 cash deposited by CRA
- Ontario OITC: $300,000 × 8% = $24,000 additional
- Total cash recovery: $129,000 — even with zero revenue and zero tax payable
Frequently Asked Questions: SR&ED Claims Canada
What is the difference between SR&ED and a regular R&D expense deduction?
A regular R&D expense deduction reduces your taxable income by the amount spent. SR&ED goes further — it provides an Investment Tax Credit (ITC) that is a dollar-for-dollar reduction in taxes owed, or a cash refund for qualifying CCPCs. On $500,000 of R&D: a regular deduction at a 26.5% Ontario corporate tax rate saves approximately $132,500 in tax. SR&ED at 35% provides $175,000 — plus you still get the deduction. The two work together, not instead of each other.
Can a startup with no revenue claim SR&ED refunds?
Yes — this is SR&ED’s most important feature for Canadian startups. A CCPC with no taxable income still receives the fully refundable 35% federal ITC on eligible expenditures up to $3 million. Ontario’s 8% OITC is also refundable. This provides critical runway funding — a startup spending $400,000 on qualifying SR&ED can receive approximately $172,000 in combined federal and provincial cash refunds, even with zero revenue.
What documentation does the CRA require for an SR&ED claim?
The CRA requires contemporaneous documentation — records created during the project, not reconstructed afterward. Essential documents include: project plans with technical specifications, hypothesis statements identifying the technological uncertainty, experiment logs or lab notebooks dated during the work, test results and analysis notes, version control logs or engineering change orders, time sheets showing SR&ED vs non-SR&ED allocation, and invoices/receipts for all claimed expenditures. The technical narrative in Form T661 must be sufficiently detailed for a CRA Research and Technology Advisor to evaluate the work independently.
How much does SR&ED preparation cost and is it worth it?
Professional SR&ED preparation typically costs 15–25% of the ITC recovered, either as a flat fee or contingency. On a $175,000 ITC, professional fees might range from $26,000 to $43,000 — leaving $132,000 to $149,000 in net recovery. Self-prepared claims have higher denial rates and typically capture fewer eligible expenditures than professionally prepared claims. For Ontario businesses with R&D spending above $100,000, professional SR&ED preparation with a qualified CPA almost always delivers a positive net return.
