SR&ED

TL;DR

Canada's flagship federal R&D tax credit: 35% refundable for CCPCs (first C$3M of spend), 15% non-refundable otherwise. Often the largest non-dilutive line.

SR&ED (Scientific Research and Experimental Development) is Canada's federal R&D tax credit programme administered by the CRA. CCPCs receive a 35% refundable investment tax credit on the first C$3M of qualifying R&D expenditure each year, paid as cash; spending above C$3M and non-CCPC spending earns a 15% non-refundable credit that reduces future federal tax. Provincial top-up credits (Ontario IRDP, Quebec R&D credits, BC SR&ED) can add another 10–37.5%.

For early-stage Canadian tech founders, SR&ED typically returns 35–50% of qualifying engineering payroll as cash, paid roughly 4–6 months after the corporate-tax filing. Specialist SR&ED consultants (typically 10–25% contingent fee) prepare the technical and financial narratives that satisfy the CRA's 'systematic investigation' test.

Formula

SR&ED Cash Refund (CCPC, first C$3M) = Qualifying R&D Spend × 35%

• Qualifying R&D Spend — Eligible engineering salaries, contractor costs (80%), materials, and overhead during the fiscal year
• 35% — Federal refundable rate for CCPCs on the first C$3M of qualifying expenditure

Provincial top-ups (Ontario, Quebec, BC) add 10–37.5% more, layered on top of the federal credit.

Worked example

A Toronto fintech CCPC spends C$2.4M on qualifying R&D in 2024. Federal SR&ED refund: C$2.4M × 35% = C$840k cash. Ontario IRDP adds C$192k (8% top-up). Total refund C$1.03M lands in mid-2025 — funding ~7 months of additional runway against C$150k/month burn.

Common pitfalls

• Submitting claims via overly aggressive contingent-fee consultants whose technical narratives draw CRA review.
• Treating SR&ED as 'free money' — a CRA review can claw back 100% of the credit if activities don't satisfy the experimental-development test.
• Losing CCPC status mid-year and missing the 35% refundable rate on the back half of qualifying spend.
