SR&ED (Scientific Research & Experimental Development) is the largest federal tax credit program for Canadian R&D — CCPCs get a refundable 35% credit on the first $3M of eligible spend plus Ontario's 8% OITC top-up. Most tech startups, manufacturers, and engineering firms qualify but don't claim. Our calculator estimates your refund in 30 seconds.

Why SR&ED matters for Ontario tech companies
The average tech startup or manufacturer leaves $40,000-$200,000 per year of SR&ED credits unclaimed. Reasons: complexity (the technical narrative scares people), audit risk (CRA reviews 1 in 10 claims), and bad advice. Insight Accounting CPA prepares CRA-defensible SR&ED claims with both the technical narrative and the financial schedule.
Frequently asked questions
Is the estimator free?
Yes. No login required. It returns an estimate — the actual claim requires a technical narrative and CRA submission.
What’s eligible vs not?
Eligible: technical work that resolves uncertainty (not routine engineering). Includes wages, contractor fees, and materials consumed. Excludes capital expenditures, marketing, sales, training.
How long does CRA take to refund?
For CCPCs filing on time, refunds typically arrive 2-4 months after T2 filing. Audited claims take 6-12 months.
What’s the audit risk?
CRA selects ~10% of SR&ED claims for review. The technical narrative is the #1 audit trigger. Insight Accounting CPA writes audit-resistant narratives.
What does Insight Accounting CPA charge to prepare a SR&ED claim?
Typical SR&ED preparation engagement is $5,000-$20,000 fixed-fee, depending on claim size and complexity. Often paid from the refund itself.
