How to Apply for
SR&ED Tax Credits
The Short Answer: SR&ED gives CCPCs a 35% refundable tax credit on eligible R&D. You must file within 18 months of your fiscal year end. The key requirement is proving 'technological uncertainty' — document your failures, they are your strongest evidence.

How does the SR&ED application process work?
It's 2026: Rates have Improved
Recent changes have expanded eligibility for some public corporations and restored capital expenditure credits. Always use the latest T661 form.
1. The "Why" (Technical Uncertainty)
You must prove you faced a technical problem that could not be solved by standard practice. This is the heart of your claim.
2. The "How" (Systematic Investigation)
You must show the steps you took—experiments, analysis, testing. Keep your lab notes, emails, and commit logs!
3. The Calculation
Sum up eligible salaries, materials, and sub-contractors. Apply the "Proxy Method" (usually best) to cover overheads.
4. File T661
Submit Form T661 and Schedule T2SCH31 with your corporate tax return (T2).

What activities are actually eligible?
SR&ED is not just for scientists in lab coats. It applies to software developers, manufacturers, and engineers solving hard problems.
- Technological Uncertainty: You didn't know *if* or *how* to achieve the result.
- Technical Content: You formulated a hypothesis and tested it.
- Advancement: You generated new knowledge (even if the project failed).
How much money can I get back?
CCPC (Canadian Private)
- Federal: 35% refundable

Foreign / Public Corp
- Federal: 15% non-refundable
- Provincial: Varies
- Note: Used to reduce taxes owed, not cash back.
Avoiding the Audit Trigger
The #1 reason claims are rejected is "Lack of Substantiation". You cannot recreate documentation at year-end.
Do:
Save dated screenshots, git commit hashes, meeting minutes, and test logs.
Don't:
Estimate time percentages (e.g., "I spent roughly 50% on R&D"). Use time sheets!
Frequently Asked Questions
Is the refund taxable?
Yes. The federal ITC (Investment Tax Credit) reduces your expenditure pool for the next year, or is included in income.
Can I file myself?
Yes, the T661 is available online. However, the technical narrative is tricky. Many companies use a consultant who charges a contingency fee (15-25% of the refund).
Does SEO or marketing count?
No. Social science, marketing, routine data collection, and style changes are specifically excluded.
Common Questions About SR&ED
1. Is there a deadline?
Yes: 18 months after your fiscal year end. This is a hard deadline. If you miss it, the credits for that year are lost forever.
2. How much do SR&ED consultants charge?
Most firms work on a contingency fee model, charging between 15% and 25% of the refund amount. You generally should not pay upfront fees for SR&ED preparation.
3. What if I fail?
Failure is good! In the eyes of the CRA, technical failure proves there was "technological uncertainty," which is a core requirement. You can claim the costs of failed experiments.
4. Do I need timesheets?
The CRA strongly prefers them. If you are audited, "estimated" time allocations are often rejected. Implement a simple time-tracking code for "R&D" in your payroll system.
5. Can I claim the CEO's salary?
Only for the time they spent directly engaged in the technical work or directly supervising it. You cannot claim time spent on sales, marketing, or general administration.
6. What is the Proxy Method?
The Proxy Method simplifies overhead calculations. Instead of itemizing every pen and paper, you claim a flat 55% of eligible salaries as overhead. This is the method chosen by 90% of claimants.
