The SR&ED Tax Credit Explained for Canadian Small Businesses (2026)

SR&ED is Canada's largest R&D tax incentive, and 2026 brought its biggest expansion in decades. Here is what it is, who qualifies, and how to claim it.

SR&ED, short for Scientific Research and Experimental Development, is the largest source of research and development funding in Canada, and most small businesses that qualify never claim it. In 2026 the program went through its biggest expansion in decades. Here is what it is, what changed, and how to claim it.

Who this is for

Any Canadian business that experiments, develops, or improves a product, process, or piece of software could qualify. This is not just for labs and tech startups. Manufacturers, food producers, software shops, and even trades can qualify when they are solving a genuine technical problem where the outcome was not obvious in advance.

What SR&ED actually is

It is a tax credit for eligible R&D work carried out in Canada. For a Canadian-controlled private corporation (CCPC), the credit can be refundable, which means you can receive cash back even in a year when you owe no tax. That refundable feature is what makes it so valuable to small companies.

What changed in 2026

The 2026 changes made the program far more generous. These are the ones that matter most for a small business.

Enhanced refundable rate 35% refundable

CCPCs earn a 35% refundable investment tax credit on eligible R&D spending within the expenditure limit. Refundable means you can receive it as cash even if you owe no tax that year.

Higher expenditure limit Up to $6 million

The annual spending that qualifies for the top rate doubled from $3 million to $6 million, so up to about $2.1 million in credits can now be refundable in a single year.

Taxable-capital phase-out raised $15M to $75M

The enhanced limit now begins to phase out at $15 million of taxable capital and reaches nil at $75 million, up from the old $10 million to $50 million band. More growing firms keep the full benefit.

Capital expenditures are back Newly eligible again

Equipment and other capital used for R&D is eligible once more, after years of being excluded. The credit on eligible capital assets is refundable up to 40%.

Effective date Tax years from Dec 16, 2024

The changes apply to tax years that begin on or after December 16, 2024, so most 2025 and 2026 filings can use them.

It is not only for CCPCs anymore. Certain Canadian public corporations controlled by residents can now access the refundable credit too. And you do not need a formal lab or a science degree. What matters is that you were resolving genuine technical uncertainty, not just doing routine work.

How to claim it

Document the work as you go. Record the technical problem, what you tried, and why the result was uncertain. Notes written at the time beat ones reconstructed at tax time.
Track your eligible costs. Wages for the people doing the work, materials consumed, and now eligible capital. Keep them separated in your books.
File form T661 with your corporate return. This is the SR&ED claim itself, filed alongside your T2 for the year.
Get a second set of eyes. A SR&ED specialist or an experienced accountant is often the difference between a trimmed claim and a full one, especially on your first.

Frequently asked questions

Who qualifies for the SR&ED tax credit?

Any Canadian business carrying out eligible R&D in Canada, meaning work to resolve genuine scientific or technological uncertainty. Canadian-controlled private corporations get the most generous, refundable version, and as of 2026 some public corporations can access refundable credits too.

How much can a small business get back from SR&ED?

A CCPC can earn a 35% refundable credit on eligible spending up to a $6 million annual limit, which works out to as much as roughly $2.1 million refunded in a year. Most small claims are far smaller, but even modest ones are often worth thousands.

Is SR&ED a grant or a tax credit?

It is a tax credit claimed through your corporate return, not an application-based grant. For a CCPC it can be refundable, so you may receive cash even with no tax owing. Create a free Inceptium profile to see the credits and grants you qualify for.
