What Are SR&ED Tax Credits?

The SR&ED program is a federal tax incentive designed to encourage Canadian businesses of all sizes and sectors to conduct research and development. Administered by the Canada Revenue Agency (CRA), the program provides:

  • Refundable tax credits for Canadian-controlled private corporations (CCPCs)
  • Investment tax credits for all qualifying corporations and individuals
  • Provincial enhancement through Ontario’s Innovation Tax Credit (OITC)

SR&ED Eligibility Criteria

Your project may qualify for SR&ED if it meets one of these three categories:

1. Experimental Development — Systematic work to advance technology or knowledge
2. Applied Research — Work with practical application in view
3. Basic Research — Work to advance scientific knowledge without specific application

The “Why” Test

The CRA uses a five-question test to determine SR&ED eligibility:

1. Was there a scientific or technological uncertainty?
2. Did the effort involve formulating hypotheses?
3. Did the work involve systematic investigation?
4. Was the approach consistent with systematic research?
5. Did it result in a technological advancement?

Many businesses assume their work doesn’t qualify. Our experience shows that manufacturing process improvements, software development, engineering optimizations, and even failed experiments often meet these criteria.

Frequently Asked Questions

How long do I have to claim SR&ED tax credits?

You must file your SR&ED claim within 18 months of the end of the tax year in which the expenditures were incurred. We recommend starting the claim process as soon as your fiscal year ends to ensure adequate time for documentation.

Can I claim SR&ED for failed experiments?

Yes. The CRA explicitly recognizes that failures can indicate systematic investigation and may qualify for SR&ED. The key is documenting what was attempted, why it was expected to work, and what was learned from the failure.

What documentation do I need for a SR&ED claim?

Contemporaneous documentation is ideal but not strictly required. Useful records include:

  • Project plans and design documents
  • Meeting notes and emails discussing technical challenges
  • Test results and prototype iterations
  • Timesheets or activity logs showing R&D time allocation
  • Source code commits and version control history (for software)

How long does the claim process take?

CRA processing times vary:

  • Initial assessment: 30-60 days for refundable credits
  • Technical review: 3-6 months if selected
  • Payment: Generally 60 days after approval for refundable claims

We recommend filing early to minimize delays.

Can startups with no tax liability benefit from SR&ED?

Absolutely. CCPCs can receive refundable cash payments even without taxable income. This makes SR&ED particularly valuable for startups and pre-revenue companies, providing essential funding for continued innovation.

Do I need to create something new to qualify for SR&ED?

Not necessarily. SR&ED focuses on overcoming scientific or technological uncertainty and achieving advancement. This can include:

  • Improving existing processes
  • Optimizing current technologies
  • Resolving persistent technical problems
  • Adapting technology to new applications

Our assessment can identify qualifying work you may not have recognized.
