SR&ED Tax Credit: The Complete Guide for Canadian Businesses

The Scientific Research and Experimental Development (SR&ED) program is Canada's largest federal tax incentive for innovation. Yet many eligible businesses leave millions on the table because they don't realize they qualify or don't know how to claim it.

This guide breaks down everything you need to know about SR&ED, written in plain English.

What is SR&ED?

SR&ED (pronounced "shred") is a federal tax incentive program that provides tax credits for businesses conducting research and development in Canada. The program reduces the after-tax cost of R&D work, making innovation more affordable.

Key Facts

  • Program Type: Tax credit (not a grant)
  • Refundable Credit (Canadian-Controlled Private Corporations): Up to 35% of eligible expenses
  • Non-Refundable Credit (Other Businesses): 15% of eligible expenses
  • Annual Claims: Over $3 billion distributed to 20,000+ Canadian businesses
  • No Sector Restrictions: Available across all industries

Who Qualifies for SR&ED?

Here's the surprising truth: if your business develops new products, improves existing ones, or solves technical problems, you probably qualify.

Eligible Business Types

  • Canadian-Controlled Private Corporations (CCPCs) - Get the highest credit rate
  • Other Canadian corporations - Lower rate but still valuable
  • Individuals and partnerships - Also eligible
  • Non-profits - Can claim in certain cases

What Activities Qualify?

SR&ED work must involve technological uncertainty and technological advancement. Here's what that means:

Technological Uncertainty

You don't know if something is possible or how to achieve it using existing technology. For example:

  • Can we make this product work at extreme temperatures?
  • How do we reduce manufacturing defects below 1%?
  • What algorithm will give us real-time processing?

Technological Advancement

Your work advances the understanding of technology, even if others elsewhere may have solved similar problems. The key is that it's an advancement for your business.

Common Qualifying Activities

āœ… Software Development

  • Developing new algorithms
  • Improving performance or scalability
  • Creating novel architectures
  • Solving technical challenges

āœ… Product Development

  • Designing new products or processes
  • Improving existing designs
  • Testing and prototyping
  • Materials research

āœ… Manufacturing Improvements

  • Process optimization
  • Quality improvements
  • Automation development
  • Efficiency gains through technical innovation

āœ… Food and Agriculture

  • New food products or processes
  • Improved growing techniques
  • Agricultural technology

āœ… Clean Tech and Environmental

  • Energy efficiency improvements
  • Emission reduction technology
  • Waste management innovation

What DOESN'T Qualify?

āŒ Market research or sales activities āŒ Routine testing or quality control (unless part of R&D) āŒ Commercial production āŒ Arts, humanities, or social sciences research āŒ Prospecting or exploring for resources

How Much Can You Get?

The credit amount depends on your business type and size.

Canadian-Controlled Private Corporations (CCPCs)

Enhanced Rate (35% refundable):

  • Applies to first $3M of qualified expenditures
  • Available if previous year's taxable income ≤ $500,000
  • And previous year's taxable capital ≤ $10M

Regular Rate (15% non-refundable):

  • Applies to expenditures above $3M
  • Or if you exceed the income/capital thresholds

Non-CCPCs and Public Companies

  • 15% non-refundable credit
  • Can reduce federal taxes owed
  • Can be carried back 3 years or forward 20 years

Example Calculation

Scenario: Small CCPC with $500,000 in eligible R&D expenses

Eligible R&D expenses: $500,000
Enhanced credit rate: 35%
SR&ED credit: $175,000

After-tax cost of R&D:
$500,000 - $175,000 = $325,000

Effective discount: 35%

Eligible Expenditures

You can claim several types of expenses:

1. Salaries and Wages

  • Employees directly engaged in SR&ED
  • Portion of time spent on eligible work
  • Includes base salary, bonuses, and benefits
  • Pro tip: Track time carefully with detailed records

2. Materials

  • Materials consumed or transformed in R&D
  • Prototypes and test materials
  • Must be directly used in SR&ED work

3. Contractor Payments

  • CCPCs: Can claim 100% of qualifying contractor payments
  • Non-CCPCs: Limited to 80% of the amount paid
  • Contractor must perform eligible R&D activities

4. Overhead (CCPCs only)

  • Proxy method: 55% of salaries/wages (easy, no receipts needed)
  • Traditional method: Actual overhead costs (more complex but potentially higher)

5. Capital Equipment

  • SR&ED-specific equipment (must be used 90%+ for R&D)
  • Depreciation allocated to SR&ED work

How to Claim SR&ED

Step 1: Identify Eligible Projects

  • Review all development work from the fiscal year
  • Identify projects with technological uncertainty
  • Document the challenges and advancements

Step 2: Track Time and Expenses

  • Maintain detailed time logs for R&D staff
  • Track materials and contractors
  • Keep technical records (design docs, test results, meeting notes)

Step 3: Prepare Technical Narrative

Describe each project:

  • What technological uncertainties existed?
  • What advancement was sought?
  • What hypothesis or approach was tested?
  • What was the outcome?

Step 4: Calculate Eligible Expenditures

  • Compile wages, materials, contractors, overhead
  • Apply the appropriate calculation methods
  • Ensure documentation supports all claims

Step 5: File Forms

  • Form T661 - SR&ED Expenditures Claim
  • Schedule T2SCH31 - Investment Tax Credit (Corporations)
  • File with your T2 corporate tax return
  • Deadline: 18 months after fiscal year-end

Best Practices for Maximizing Your Claim

1. Document Everything

The CRA may review your claim. Good documentation includes:

  • Project plans and technical specs
  • Test results and analysis
  • Meeting minutes discussing technical challenges
  • Source code changes and commit logs (for software)
  • Design iterations and failures
  • Time tracking records

2. Track Time Accurately

  • Don't estimate after the fact
  • Use time tracking software or timesheets
  • Separate R&D time from routine work
  • Be conservative and honest

3. Use the Proxy Method (CCPCs)

Unless your actual overhead is significantly higher, the 55% proxy method is simpler and less risky.

4. Work with Experts

SR&ED claims can be complex. Consider:

  • SR&ED consultants (typically work on contingency)
  • Specialized accountants
  • CRA's pre-claim consultation service (free)

5. Keep Claims Reasonable

  • Don't overstate or exaggerate
  • Focus on quality over quantity
  • Be prepared to defend your claim

Common Mistakes to Avoid

1. Not Claiming at All

Many businesses assume they don't qualify. If you develop anything new or solve technical problems, you likely do.

2. Poor Documentation

"We did R&D but didn't document it" is the most common reason claims are reduced. Start tracking now.

3. Including Non-Eligible Work

Don't inflate claims with routine work or commercial production. This invites scrutiny.

4. Missing the Deadline

You have 18 months after your fiscal year-end to file. Missing it means losing the credit.

5. Not Consulting Experts

First-time claims benefit enormously from expert review. The cost is usually worth it.

SR&ED vs. Other R&D Programs

SR&ED works great alongside other programs:

ProgramTypeBest For
SR&EDTax creditOngoing R&D across all sectors
NRC IRAPGrant + advisoryHigh-growth tech companies
CanExport InnovationGrantDeveloping products for export
Regional programs (ACOA, Alberta Innovates)GrantLocation-specific innovation

Strategy: Stack programs where possible. Use grants for upfront funding, then claim SR&ED on the same expenses (where allowed).

FAQs

Q: Can I claim SR&ED on failed projects? A: Yes! Failures are eligible if the work met the SR&ED criteria. Document what you learned.

Q: Do I need patents to claim SR&ED? A: No. Patents are irrelevant to SR&ED eligibility.

Q: Can I claim the same expenses for SR&ED and other grants? A: It depends on the grant program. Some allow it, others don't. Check each program's rules.

Q: What if the CRA reviews my claim? A: This is normal. Provide documentation, answer questions honestly, and work with them constructively.

Q: Should I use a consultant? A: For first claims or complex situations, yes. They often increase claims by more than their fee.
