If your business is designing new products, improving processes, or writing code that pushes past what’s already documented in your field, you may be sitting on one of the most valuable — and most underused — tax incentives in Canada: the Scientific Research and Experimental Development (SR&ED) program.
Every year, the SR&ED tax credit returns billions of dollars to Canadian businesses that are solving real technical problems, whether that work happens in a lab, a workshop, or a codebase. Yet many companies either don’t realize their work qualifies, or assume SR&ED is reserved for university researchers and pharmaceutical labs. It isn’t. This guide breaks down what SR&ED actually is, who qualifies, how much you could claim in 2026, and what the CRA expects to see in a claim.
What Is SR&ED?
SR&ED (Scientific Research and Experimental Development) is a federal tax incentive program administered by the Canada Revenue Agency (CRA) that encourages Canadian businesses of all sizes and sectors to conduct research and development in Canada. It’s the largest single source of federal government support for business R&D, supporting more than 22,000 businesses annually.
Rather than a grant you apply for and wait to be awarded, SR&ED is a tax incentive: your business claims eligible R&D expenditures on its tax return in the form of a deduction and, in many cases, an investment tax credit (ITC) that can be fully or partially refundable — meaning the CRA can pay it out even if your company owes little or no tax.
Who Can Qualify for SR&ED?
SR&ED eligibility isn’t determined by your industry, your company’s size, or whether you have a dedicated “R&D department.” It’s determined by the nature of the work itself. Businesses across software, manufacturing, engineering, construction, food science, agriculture, cleantech, and healthcare all successfully claim SR&ED every year, provided their work meets three core criteria set out by the CRA.
The Three-Part SR&ED Eligibility Test
Every project must satisfy all three of the following criteria — meeting only one or two is not enough:
- Technological uncertainty — Could a competent professional in your field have predicted the outcome, approach, or result in advance using existing knowledge and standard practice? If not, uncertainty existed.
- Systematic investigation — Did your team follow a methodical process (forming a hypothesis, testing it, analyzing results, adjusting) to resolve that uncertainty, rather than trial-and-error without structure?
- Technological advancement — Did the work generate new knowledge or capability, even if the end result wasn’t commercially successful? A failed experiment can still qualify — it generated knowledge about what doesn’t work.
| Quick self-check Ask: “Could we have looked this up or bought an off-the-shelf solution instead of experimenting?” If the honest answer is no — because no existing knowledge, tool, or published method could tell you the outcome — your project may involve SR&ED-eligible work. |
What SR&ED Tax Credits Are Worth in 2026
Following the Budget 2025 Implementation Act (Bill C-15), which received Royal Assent on March 26, 2026, the SR&ED program was expanded significantly — the largest enhancement to the program in over a decade. Current federal rates and limits are:
- Canadian-Controlled Private Corporations (CCPCs) can earn a fully refundable 35% investment tax credit on up to $6 million of qualifying SR&ED expenditures annually (up from $3 million) — worth up to $2.1 million per year in refundable credits.
- The taxable capital phase-out range for the enhanced rate was widened from $10–$50 million to $15–$75 million, allowing more mid-sized companies to keep access to the enhanced rate.
- Eligible Canadian public corporations can now access the enhanced 35% refundable rate on qualifying expenditures, a benefit previously limited to CCPCs.
- Capital expenditures are once again eligible for both the income deduction and the investment tax credit, reversing rules that had excluded them since 2014.
- Non-CCPCs, and CCPC spending above the enhanced limit, generally earn a 15% non-refundable (or partially refundable) tax credit.
On top of the federal credit, most provinces offer their own SR&ED-equivalent tax credits that stack with the federal incentive, meaning the effective return on eligible R&D spending can be substantially higher depending on where your business operates.
What Activities Are Eligible?
SR&ED-eligible work generally falls into three categories recognized by the CRA:
- Basic research — work undertaken to advance scientific knowledge without a specific practical application in mind.
- Applied research — work undertaken to advance 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.
In practice, this includes activities like developing new algorithms or system architectures where the approach isn’t documented anywhere, testing new material formulations, engineering products to perform under conditions existing designs weren’t built for, and building manufacturing or production processes that don’t yet have an established method.
What Generally Doesn’t Qualify
Not all technical work is SR&ED. The CRA draws a clear line between experimental development and routine engineering or standard practice. Activities that typically don’t qualify on their own include:
- Routine testing, quality control, or debugging using known methods
- Style changes, cosmetic updates, or minor customization of existing products
- Market research, sales, and promotional work
- Commercial production and routine data collection
That said, these activities can sometimes be claimed as support work when they are directly connected to an eligible experimental development project — which is why accurate documentation matters.
Documentation: The Single Biggest Factor in a Successful Claim
The CRA has been explicit: documentation is the most important factor in whether a claim is accepted. Contemporaneous records — created as the work happened, not reconstructed afterward — are what demonstrate technological uncertainty, systematic investigation, and technological advancement. Useful documentation includes:
- Project and design notes, hypotheses, and test plans
- Version control history, commit logs, and code comments (for software)
- Lab notebooks, test results, and prototype iterations
- Meeting notes discussing technical obstacles and decisions
- Time tracking by project or technical activity
Businesses that build these habits into their regular workflow — rather than piecing together evidence at tax time — consistently submit stronger, more defensible claims.
