If you are filing your first SR&ED claim, here is the one thing to understand up front: the program is generous, but the paperwork is unforgiving. A good consultant earns their keep by finding eligible work you would have overlooked and by translating your engineering story into the evidence the CRA needs to approve it.
The gap isn’t between companies that innovate and those that don’t. It’s between companies that recognize their innovation and document it properly, and those that don’t. First-time claimants almost always sit in the second group, not because their work doesn’t qualify, but because nobody told them what to keep.
Below are eight facts worth knowing before you sign with anyone. They will help you ask better questions, avoid the common traps, and choose a partner instead of just a form-filler.
The Scientific Research and Experimental Development (SR&ED) program is the single largest source of federal R&D support in Canada, returning more than $4 billion a year to roughly 20,000 claimants. It rewards companies that solve technical problems standard practice can’t answer.
Crucially for startups, the refundable portion is paid as cash even if you owe no tax. You do not need to be profitable to benefit. If you want the full picture of the program’s scale, our State of SR&ED report breaks down the numbers.
The industry standard is a contingency fee: the consultant takes a percentage of whatever refund you receive, typically between 10% and 25%. The appeal is obvious, since there is no upfront cost. The downside is that the percentage repeats every year, so a firm that keeps claiming can quietly become one of your largest recurring expenses.
A smaller group of firms charges a flat fee instead. Here is how the two models compare in plain terms.
Contingency (percentage) pros: no upfront cost, fee scales down automatically if your claim is small, and the firm is motivated to maximize the number.
Contingency cons: the cost compounds year after year, and on a large or growing claim you can pay far more than the work is worth.
Flat fee pros: you know the cost before you start, it usually works out cheaper over the life of a claim, and the incentive is to prepare an accurate, defensible claim rather than an inflated one.
Flat fee cons: there is a defined cost regardless of refund size, so it makes the most sense once your claim is large enough to matter.
SRED.ca uses the flat-fee model and is, as far as we know, the only SR&ED provider in Canada that publishes its pricing on its website. You can see the numbers on our flat-fee pricing page and read a fuller breakdown in our guide to SR&ED consultant costs in Canada.
Success or failure in meeting your business objective is not what determines eligibility. What matters is whether you faced genuine technological uncertainty and worked through it systematically. A dead end that taught you something still counts.
First-time claimants routinely disqualify themselves in their own heads, assuming that because a feature never shipped or an experiment flopped, there is nothing to claim. Often the opposite is true. The failed attempts are frequently the clearest evidence of the systematic investigation the CRA is looking for.
If you file as a corporation, your SR&ED claim is due 18 months after the end of the fiscal year in which the work happened. For example, if your fiscal year ends December 31, 2024, your filing deadline is June 30, 2026. This deadline is effectively absolute, and the CRA very rarely accepts late claims. (Unincorporated businesses and trusts follow different timelines, so confirm yours.)
This is one of the most expensive facts for first-timers to learn the hard way. A refund you were fully entitled to can vanish simply because the window closed. A good consultant tracks these dates for you so a missed deadline never costs you a year of R&D funding.
If you paid an arm’s-length Canadian contractor to perform eligible R&D in Canada on your behalf, and the contractor is a taxable supplier, you can generally claim 80% of that eligible cost. Salaries, some materials (eligible when they are consumed or transformed in the work), and certain overhead can also qualify.
This matters for startups that lean on freelancers and agencies instead of a full in-house team. The eligible costs are often larger than founders expect, which is exactly the kind of value a consultant surfaces when they map your spend against the rules.
For Canadian-controlled private corporations (CCPCs), the enhanced credit refunds 35% on the first $6 million of qualifying SR&ED expenditures. That is worth up to $2.1 million in refundable credits in a single year, and it applies for taxation years that begin on or after December 16, 2024.
The $6 million ceiling is recent. Budget 2025, enacted through Bill C-15 (which received Royal Assent on March 26, 2026), raised the expenditure limit from $3 million to $6 million, effectively doubling the maximum refundable credit for growing companies. Treat $2.1 million as a ceiling rather than a default: the enhanced rate phases out as your taxable capital grows, and the limit is shared among associated corporations. Combined federal and provincial credits push the effective return higher, though not by simple addition, and how much higher depends on your province.
Here is what that can look like in round numbers. Suppose your CCPC spends $500,000 on eligible SR&ED salaries and pays a Canadian contractor $100,000 for eligible work, of which 80% ($80,000) is claimable. That is $580,000 of qualifying expenditure. At the 35% enhanced refundable rate, that works out to roughly $203,000 back as a cash refund, before the prescribed-proxy overhead amount and any provincial credit, which usually push the figure higher. Numbers like these are why the $6 million ceiling matters so little for most first-time claimants: nearly all of your qualifying spend earns the top rate.
The CRA does not take your word for it. Every eligible project has to show three things: technological uncertainty, systematic investigation, and technological advancement. If your records don’t tell that story clearly, the refund shrinks or disappears, no matter how real the work was.
The records that hold up are the ones created while the work is happening: technical diaries, experiment logs, progress notes, and time tracking. Reconstructing them from memory a year later is where first-time claims fall apart. This is why the strongest consultants build documentation habits into your workflow from day one rather than scrambling at filing time. Our SR&ED Academy covers how to do this in-house if you would rather learn the ropes yourself.
Filing the claim is only half the job. If the CRA selects your claim for review, someone has to defend it, and refundable claims selected for review can take up to 180 days to process from a complete claim. A consultant who files and disappears leaves you to face that alone.
Before you sign, ask directly whether audit defense is included or billed separately, and what happens if the CRA reduces your claim. The answer tells you whether you are hiring a partner or renting a form-filler. For more on this, see our guides on how to choose an SR&ED consultant and the questions to ask an SR&ED consultant before you commit.
Before you file your first claim, or before your first call with a consultant, get these in order. Having them ready is the difference between a smooth claim and a stressful one.
Most SR&ED firms still work the old way: a percentage of your refund, vague deliverables, and a consultant who moves on once the cheque clears. SRED.ca was built to do the opposite.
We charge a transparent flat fee, billed monthly, and we publish it openly. We support you year-round with documentation tracking rather than a once-a-year scramble. And we back the work with Canada’s only SR&ED guarantee: any claim we prepare from start to finish is guaranteed to be approved for at least 75% of its filed value, or our fees are waived, audit defense included. If there is no eligible work in your year, you don’t pay.
For a first-time claimant, that means you know the cost before you start, you are not alone if the CRA asks questions, and your consultant is motivated to file an accurate claim rather than an inflated one.
Your first SR&ED claim does not have to be intimidating. The program is designed to reward exactly the kind of technical risk-taking you are already doing. The facts above, from how fees work to why documentation matters more than the size of your idea, put you in a position to choose a consultant on your terms.
Ask about fees, deadlines, and audit defense before you sign. Keep your records as you go. And if you want a second opinion on whether your work qualifies, you can book a free consultation and we will tell you honestly, even if the answer is not yet.
No, you can file an SR&ED claim yourself. But first-time claimants often leave money on the table or trigger a CRA review because they miss eligible work or document it poorly. A consultant is most valuable when your refund is large enough that a bigger, better-defended claim outweighs the fee.
Most consultants charge a contingency fee of roughly 10% to 25% of your refund, repeated every year you claim. A smaller group, including SRED.ca, charges a published flat fee instead, which usually costs less over the life of a claim. You can see SRED.ca’s pricing on the pricing page.
For a corporation, the claim is due 18 months after the end of the fiscal year in which the work took place. For a fiscal year ending December 31, 2024, the deadline is June 30, 2026. The CRA very rarely accepts late claims, so a missed deadline usually means the refund for that year is lost.
Yes. Eligibility depends on whether you faced technological uncertainty and investigated it systematically, not on whether the project succeeded. Failed experiments often provide the clearest evidence that your work qualifies.
For Canadian-controlled private corporations, the enhanced credit refunds 35% on the first $6 million of qualifying expenditures, worth up to $2.1 million per year before phase-outs. Combined federal and provincial credits are higher than the federal credit alone, though not by simple addition, and how much higher depends on your province. The refundable portion is paid in cash even if your company is not yet profitable.
Ask how they charge (flat fee or percentage), whether audit defense is included or billed separately, what happens if the CRA reduces your claim, and how they capture documentation through the year. The answers reveal whether you are hiring a long-term partner or a one-time form-filler.
