The most expensive SR&ED mistake isn’t a bad claim. It’s never filing one. Every year, Canadian companies do genuinely eligible R&D and walk right past the refund, usually because of a belief about themselves that isn’t true. The gap isn’t between companies that innovate and those that don’t. It’s between companies that recognize their innovation and those that don’t. Here’s why eligible companies miss SR&ED, and how to tell if you’re one of them.
They miss it because they assume they don’t qualify, and never check. The reasons are almost always a misunderstanding of who and what the program is for. Here are the beliefs I hear most, and why each one is wrong.
Plenty of ordinary software work qualifies, as long as part of it involved genuine technical uncertainty. You don’t have to be inventing something the world has never seen. If your team hit a problem that standard practice couldn’t solve and had to experiment to get past it, that can be SR&ED, whatever you call your day job. It doesn’t even have to have worked.
Small companies are often the ones that need the cash most, and a claim doesn’t have to be huge to be worth filing. Even a modest claim can return real money to a startup, and it’s exactly the refundable cash that helps extend a runway.
Neither is true. For a qualifying CCPC, the enhanced credit is refundable, so it’s paid as cash even when you make no profit and owe no tax. And you don’t need a lab, scientists or a research department. A normal development team doing uncertain work can qualify on the same terms.
The program has rules, but a well-built claim, one that addresses the three tests and ties the evidence to the costs, is straightforward and defensible, not a gamble. Most of the perceived risk comes from filing a weak claim, which is exactly what good preparation avoids. Doing nothing is the option that guarantees you get zero.
A bad first experience often comes down to a weak claim or a poor fit with a provider, not that you’re ineligible. Eligibility depends on that year’s work, evidence and expenditures, not your last filing. A claim framed around the uncertainty, backed by evidence and costed properly, often looks very different from the one that disappointed you.
It costs you the entire refund for every year you don’t claim, and those years don’t wait. For corporations, the filing deadline is 18 months after fiscal year-end, and the CRA very rarely accepts late claims. So a year you skip isn’t deferred, it’s gone. Miss SR&ED for a few years running and the compounded cost can run into six figures of credits you could have claimed and never did.
Assuming you don’t qualify can cost a full refund. Take a CCPC that nearly skipped SR&ED because “we just build software.” A quick review found $300,000 of eligible salaries and a $25,000 arm’s-length Canadian contractor (claimable at 80%, so $20,000), for a qualifying base of about $320,000.
At the 35% enhanced federal rate, that’s roughly $112,000 in federal credit before the prescribed-proxy overhead amount and provincial credits. For an eligible CCPC that credit is refundable, paid as cash even in a loss year, applies to the first $6 million of qualifying expenditures, and phases out with taxable capital, with the limit shared among associated corporations. Had they trusted the assumption instead of checking, that was the money they’d have left behind. This is illustrative, so your numbers will vary. See our State of SR&ED overview for the wider picture.
You may be missing an SR&ED claim if your team faced technological uncertainty, tested approaches to resolve it, and was pushing for a technical advancement. If several of these are true, it’s worth a proper look before another year’s deadline passes.
SRED.ca charges a flat fee, billed monthly, never a percentage or contingency fee, which usually works out to roughly half the lifetime cost of a percentage-based firm. As far as we know, we’re the only SR&ED provider that publishes its pricing on its website. A quick conversation is usually enough to tell whether you’ve been missing eligible work, and there’s no cost to find out. We’re CPA-owned, audit defense is included, and if the CRA approves less than 75% of the filed claim we waive our fees, as set out in our 75% guarantee. If there’s no eligible work in your year, you don’t pay.
The companies that miss SR&ED almost never do it on purpose. They just assume it isn’t for them, and the deadline quietly closes on another eligible year. If you’re doing real technical work, don’t let a wrong assumption cost you the refund. You aren’t alone in the valley. Grab a free consultation and we’ll tell you honestly whether there’s a claim worth making. The CRA’s SR&ED program page has the official criteria.

Eligible companies miss SR&ED most often because they assume they don’t qualify: that software isn’t R&D, that they’re too small, or that the credit is only for profitable companies or research labs.
If your team hit technical problems that standard practice couldn’t solve and had to experiment to get past them, you may have eligible work. The clearest sign is uncertainty: at the start, you didn’t know whether or how it could be done. A short review can confirm it.
Yes. For a qualifying CCPC, the enhanced credit is refundable, so it’s paid to you as cash even in a year with no profit and no tax owing. That’s one of the main reasons early-stage companies shouldn’t assume SR&ED isn’t for them.
No. A normal development or engineering team qualifies when its work meets the three tests: technological uncertainty, systematic investigation, and technological advancement. Job titles and a formal research department aren’t required.
Probably not. A claim doesn’t have to be large to be worth filing, and the refundable cash often matters most to smaller companies. The only way to know what yours is worth is to look at the eligible work you actually did.
Only within the window. For corporations, you have 18 months after fiscal year-end to file, and the CRA very rarely accepts late claims. Any eligible year still inside that window can be claimed, but once it closes, that year is gone.
Filing a claim doesn’t automatically trigger a review, and a legitimate, well-documented claim is a normal part of the program. Claims can be selected for review, which is why building a defensible claim and keeping evidence matters, but the fear of a review isn’t a good reason to skip a credit you may qualify for.
