If your company is claiming SR&ED tax credits, you're already ahead of many Canadian businesses. But are you claiming everything you're entitled to? Here are five proven strategies to maximize your SR&ED refunds.
1. Track R&D Activities Year-Round
Picture a dev team in October trying to remember which February sprint involved genuine technical uncertainty and which was just routine bug-fixing. That's the trap of treating SR&ED as a year-end exercise: by the time you're preparing the claim, the details that would have made a strong narrative are already fuzzy or gone.
Best Practice: Implement continuous tracking of R&D activities. This can be as simple as:
- Weekly R&D activity logs
- Project-specific time tracking
- Regular documentation of technical challenges and solutions
Modern tools like Glauq can automate much of this, integrating with your existing workflows (Slack, Jira, GitHub) to capture R&D activities in real-time.
2. Expand Your Definition of "R&D"
Many companies have a narrow view of what constitutes SR&ED-eligible R&D. They think of lab work or major product development initiatives, missing smaller but qualifying activities.
Activities often overlooked include:
- Performance optimization efforts
- Security improvements involving technical uncertainty
- Integration challenges with third-party systems
- Scaling issues requiring novel solutions
- Failed experiments (yes, these count too!)
If work involved technological uncertainty and systematic investigation, it might qualify, regardless of whether it succeeded.
3. Document Technical Uncertainty
Say your team tried the obvious approach first, watched it fail under real conditions, and spent real time testing alternatives before landing on something that worked. That's the kind of story CRA reviewers want to see. The agency requires demonstration of "technological uncertainty": the idea that achieving your objective couldn't be done using standard practice or readily available knowledge.
Strong documentation includes:
- What you were trying to achieve
- Why existing solutions didn't work
- What alternatives you investigated
- The technical challenges you encountered
- How you resolved them (or why you couldn't)
Pro tip: Document uncertainties at the start of a project, not just the solutions at the end. This creates a clearer narrative for the CRA.
4. Properly Allocate Employee Time
Salaries are usually the single largest component of a SR&ED claim. Yet many companies under-claim because they don't properly allocate employee time to R&D activities.
Strategies for better time allocation:
- Use project codes that distinguish R&D from non-R&D work
- Train employees to recognize SR&ED-eligible activities
- Review time allocations quarterly to catch underreported R&D
- Include time for planning, testing, and iteration, not just coding
Remember: supporting activities (testing, documentation, data collection) that are directly related to SR&ED work are also eligible.
5. Don't Forget Overhead and Materials
Beyond salaries, SR&ED claims can include materials consumed, contractor costs, and a portion of overhead:
- Materials consumed: Components, supplies, and materials used in R&D
- Contractor costs: Payments to third parties for R&D work in Canada
- Overhead: A portion of rent, utilities, and other expenses related to R&D
The proxy method lets you claim a prescribed proxy amount of 55% of your SR&ED salary base in place of itemizing overhead, but depending on your situation, the traditional method might yield higher claims. Not sure what your total could be? Try our SR&ED calculator for a quick estimate.
Bonus: Get Expert Review
Even with perfect documentation, the nuances of SR&ED can be tricky. A claim that seems straightforward might be missing key elements that maximize value — or include red flags that trigger audits.
Working with a qualified SR&ED expert, supported by AI tooling that organizes the evidence for them, can help you:
- Identify additional eligible activities
- Strengthen technical narratives
- Avoid common audit triggers
- Ensure compliance with current CRA guidelines
Taking Action
Maximizing your SR&ED claim isn't about gaming the system — it's about ensuring you claim every dollar you're legitimately entitled to. With proper tracking, expanded awareness, and strong documentation, most companies can significantly increase their refunds.
Start implementing these strategies today, and your next SR&ED claim could be your best one yet.
Frequently asked questions
Do failed experiments qualify for SR&ED? Yes. If the work involved technological uncertainty and systematic investigation, it can qualify regardless of whether it succeeded. Failed experiments are among the most commonly overlooked eligible activities. The program rewards the attempt to resolve uncertainty, not just successful outcomes.
What is the proxy method for SR&ED overhead? The proxy method lets you claim a prescribed proxy amount of 55% of your SR&ED salary base in place of itemizing overhead expenses like rent and utilities. Depending on your situation, the traditional method of itemizing actual overhead might yield a higher claim, so it's worth comparing both.
What's the biggest mistake companies make with SR&ED claims? Treating SR&ED as a year-end exercise. By the time the claim is being prepared, important technical details have been forgotten and eligible work goes unclaimed. Continuous tracking, meaning weekly activity logs, project-specific time tracking, and documenting challenges as they happen, is the single highest-impact fix.
Can I claim contractor costs in a SR&ED claim? Yes, payments to third parties for R&D work performed in Canada are eligible expenditures, alongside salaries, materials consumed during R&D, and a portion of overhead.
Do provincial credits simply add to the federal SR&ED rate? No. Provincial credits stack with the federal credit but reduce the federal expenditure base, so the rates don't simply add. British Columbia's effective combined rate is roughly 41.5%, and Quebec's roughly 54.5% on the first tier — lower in each case than adding the headline percentages together.
Don't forget that provincial credits stack with the federal one, though they reduce the federal expenditure base, so the rates don't simply add. Companies in British Columbia see an effective combined rate of roughly 41.5%, and Quebec roughly 54.5% on the first tier. See the full breakdown in our SR&ED guide for 2026.
