Introduction
The Scientific Research and Experimental Development (SR&ED) program is the Canadian federal government's primary mechanism for incentivising innovation. For eligible Canadian-controlled private corporations (CCPCs), it provides a refundable tax credit on qualifying expenditures — meaning the credit results in a cash refund even if the company owes no income tax.
For early-stage tech companies with significant development costs and limited revenue, SR&ED can be a meaningful source of cash. For many founders, it is also poorly understood — either overclaimed (creating audit risk), underclaimed (leaving money behind), or not claimed at all.
What Is SR&ED?
SR&ED is a federal income tax incentive administered by the CRA that allows businesses to deduct qualifying R&D expenditures and, for eligible corporations, to receive a refundable investment tax credit (ITC) on those expenditures.
The program covers three types of activities:
• Basic research: Work undertaken for the advancement of scientific knowledge without a specific practical application in view
• Applied research: Work undertaken for the advancement of scientific knowledge with a specific practical application in view
• Experimental development: Work undertaken to achieve technological advancement for the purpose of creating new, or improving existing, materials, devices, products, or processes
The vast majority of SR&ED claims by tech companies fall under experimental development — work done to develop or improve software, systems, or technology products.
What Qualifies for SR&ED
Not all development activity qualifies. The CRA applies specific criteria to determine eligibility:
Technological uncertainty: There must be a scientific or technological uncertainty — something the company does not know how to do and cannot determine through standard practice or routine engineering.
Scientific or technological content: The work must aim to resolve that uncertainty through a systematic investigation.
Technological advancement: The work must result in advancement of the general knowledge base, not just a business outcome.
The CRA does not require that the work succeed. A failed experiment that genuinely tried to resolve a technological uncertainty may still qualify. What matters is the nature of the work, not its commercial outcome.
Routine debugging, simple adaptation of existing technology, and software development that does not involve technological uncertainty generally do not qualify.
Qualifying Expenditures
For CCPCs with under $50 million in taxable capital (and under $800,000 in prior-year income for the enhanced credit), qualifying SR&ED expenditures include:
• Wages of employees directly engaged in SR&ED activities (and a portion of wages for support activities)
• Contractor costs for SR&ED work performed in Canada (subject to limits)
• Materials consumed in SR&ED activities
• Overhead costs, which can be calculated using a proxy method (65% of directly engaged employee wages)
The refundable federal ITC rate for eligible CCPCs is 35% on the first $3 million of qualified expenditures. The rate is 15% on amounts above that threshold and for non-CCPCs. Ontario provides an additional provincial credit for qualifying SR&ED.
Documentation: The Critical Point
The CRA requires that SR&ED claims be supported by contemporaneous documentation — records created at the time the work was performed, not reconstructed after the fact. This is one of the most common SR&ED compliance failures.
Documentation should include records of technological uncertainties identified, hypotheses tested, experiments conducted, results observed, and conclusions reached. Project records, technical specifications, git commit logs, testing frameworks, and development journals all contribute to a defensible SR&ED claim.
Tech founders who do not document their development process as they go often find that their SR&ED claims are reduced or denied on audit — not because the work did not qualify, but because it cannot be demonstrated.
Filing Deadlines
An SR&ED claim must be filed within 18 months of the end of the taxation year in which the expenditures were made. Missing this deadline means the claim is permanently lost — there is no mechanism to file late. This is another reason why identifying SR&ED activity early in the year, rather than at filing time, is important.
When to Speak With a CPA
SR&ED claims should be prepared with both technical and financial input. Some CPA firms work with technical writers or SR&ED consultants who are experienced in documenting qualifying activity. The quality of the claim — and its defensibility on review — depends on the quality of the underlying documentation and the accuracy of the financial schedules.
