Canada SR&ED Tax Credit — Federal R&D Incentive Explained

The SR&ED program is Canada’s largest federal R&D incentive, returning up to 35% of qualifying expenditures to Canadian businesses. Learn who qualifies, what expenses are eligible, and how to file.

What is the SR&ED tax credit?

Scientific Research and Experimental Development (SR&ED) is a federal tax credit program administered by the Canada Revenue Agency (CRA). It reimburses eligible R&D expenditures through an Investment Tax Credit (ITC) applied against federal tax — or paid as a cash refund for Canadian-controlled private corporations (CCPCs). The program is available to any Canadian corporation, trust, or individual conducting eligible R&D in Canada.

SR&ED is not a grant. It is a tax credit calculated as a percentage of qualified expenditures — wages, contractor costs, and materials directly consumed in eligible work. The credit is calculated when you file your T2 corporate tax return, with a separate T661 form detailing the technical projects.

Who qualifies for SR&ED in Canada?

Any Canadian company doing work that meets CRA’s three-part eligibility test may qualify: the work must involve genuine technological uncertainty, follow a systematic investigation, and seek technological advancement. The industry doesn’t matter — biotech, software, manufacturing, cleantech, and medtech all qualify if the work passes the test.

Federal ITC rates: what you can claim

CCPC rate

35% refundable ITC on the first $3 million of qualified expenditures. This is the most favourable rate and applies to most Canadian startups and private companies.

The phase-out begins when taxable income or taxable capital exceeds CRA thresholds. Larger CCPCs and non-CCPCs receive a 15% non-refundable ITC. Combined with provincial credits, total benefits often exceed 40–50% of eligible payroll.

How to file an SR&ED claim

Filing SR&ED involves your accountant submitting Form T661 (Scientific Research and Experimental Development Expenditures Claim) and Schedule 31 alongside your T2 corporation tax return. The T661 requires project descriptions — written in CRA’s technical language — that document the uncertainty, the systematic investigation, and the advancement sought.

Most founders find the technical writing the hardest part. SREDY.IO generates T661-ready narratives, financial schedules, and an evidence index for a flat fee, giving your accountant a complete, structured package to review and file.

Common questions

What is the federal SR&ED ITC rate for CCPCs?

Canadian-controlled private corporations (CCPCs) receive a 35% refundable Investment Tax Credit on the first $3 million of qualified SR&ED expenditures in a tax year. Non-CCPCs receive a 15% non-refundable ITC. The refundable credit means a cash refund even if your company has no tax payable.

When is the deadline to file an SR&ED claim?

The claim must be filed within 18 months of the corporation's tax year-end. For example, a December 31, 2025 fiscal year has until June 30, 2027. Missing this deadline forfeits the credit — there are no extensions.

Can a pre-revenue startup claim SR&ED?

Yes. Because the CCPC credit is fully refundable, a pre-revenue company with no tax payable still receives the credit as a cash refund from CRA. This makes SR&ED one of the few government programs that genuinely benefits early-stage companies.

What is the difference between a refundable and non-refundable ITC?

A refundable ITC is paid out as cash by CRA regardless of whether the company owes tax. A non-refundable ITC can only reduce federal tax payable — any excess is carried back three years or forward twenty years, but is never paid in cash.

Do provincial SR&ED credits stack with the federal credit?

Yes. Most provinces offer their own R&D incentives that stack on top of the federal SR&ED ITC. Ontario's OITC, Quebec's RTC, and British Columbia's credits can significantly increase the total benefit. Your accountant should claim both when applicable.
