You Just Got Acquired. What Happens to Your SR&ED Credits?

Canadian founders assume that unclaimed SR&ED credits survive an acquisition. Sometimes they're right. Sometimes they walk away from hundreds of thousands of dollars in refundable ITCs that disappeared the moment the deal closed.

The term sheet said nothing about this

A Toronto AI company closes a $12M Series B. The lead investor is a US-based fund that takes a majority stake, placing two board members and retaining the right to lead a future process. Eighteen months later, a larger US acquirer buys the company. The deal closes in October.

The founders had filed SR&ED claims for years two and three of their operations but hadn't yet filed for year four — the year of the acquisition. Year four was their biggest R&D year. Eight engineers, aggressive product development, significant technical investigation. They estimated the year-four claim at $280,000 in qualified expenditures, representing roughly $98,000 in refundable federal credits.

What their M&A lawyer didn't flag — and what their accountant noticed only after the deal had closed — was that the moment the US acquirer took control, the company lost its CCPC status. It was no longer a Canadian-Controlled Private Corporation. And the enhanced 35% refundable ITC rate that made that $98,000 possible? Gone.

The work still qualified. The claim could still be filed. But the rate dropped from 35% refundable to 15% non-refundable — available to offset future taxes the company would likely never owe in Canada. The practical value of the credit fell from $98,000 in cash to something close to zero.

This scenario isn't rare. It plays out whenever a Canadian company loses its CCPC status through an acquisition — by a US strategic, a foreign PE fund, or any non-Canadian controlling party. The SR&ED program has two different credit regimes, and the difference in value between them is not subtle.

The two SR&ED credit regimes — and why CCPC status is everything

Canada's SR&ED program provides different ITC rates depending on the company's corporate structure and size. The distinction that matters most for startups is between CCPC and non-CCPC status.

Canadian-Controlled Private Corporation (CCPC) with less than $10M in prior-year taxable capital: 35% federal ITC, fully refundable. This is the regime most tech startups operate under. It means real cash back — even with no tax owing.
CCPC with $10M–$50M in prior-year taxable capital: graduated phase-out of the enhanced rate, moving toward the general 15% rate as you cross the threshold.
Non-CCPC (including foreign-controlled corporations and public companies): 15% federal ITC, generally non-refundable. The credit offsets tax owing but produces no cash if you have no tax liability.

The math: $1M in qualifying SR&ED expenditures as a CCPC = up to $350,000 in refundable credits. Same $1M as a non-CCPC = $150,000 in non-refundable credits that may never generate actual cash. The difference is $350,000 vs. likely $0 if the company has no Canadian tax owing.

CCPC status is determined by who controls the corporation. If a non-Canadian entity — US company, PE fund, or individual — holds voting control, the corporation is no longer a CCPC. That status changes the moment control changes, not at year-end, not at the next filing date.

What can survive an acquisition — and what cannot

Not every acquisition destroys SR&ED value. It depends on the structure, the timing, and whether the company's tax filings were current going in.

Credits that have already been claimed and refunded are gone — they're cash in the bank. Nothing in an acquisition changes that. The question is about unclaimed credits: ITCs that have accumulated but haven't yet been applied, and future credits on work already done.

Filed claims, refund not yet received: the refund follows the filing. If a CCPC filed a claim, got the refund issued but not yet deposited — the acquirer typically negotiates who receives it as part of closing adjustments. CRA pays it to the legal entity that filed.
Unclaimed prior years (deadline still open): if a CCPC hasn't filed for prior years but the 18-month window is still open, it can file those years as a CCPC and claim the refundable rate — even post-acquisition, as long as the company was a CCPC during the qualifying year.
Current year, partially into the period: the year gets split. Expenditures during the CCPC period qualify at 35%. After control changes, the rate changes. This requires a deemed year-end calculation, which most M&A CPAs handle as part of closing.
ITC carryforwards from prior years: unused ITCs (generated in prior years but not applied against taxes) can be carried forward 20 years under the Income Tax Act. They survive acquisitions. But if they were non-refundable to begin with, they still need taxable income to apply against — which a loss-stage startup under a US parent may not generate in Canada.

The timing play that changes everything

A Waterloo company receives a letter of intent in March. Their fiscal year ends December 31. The deal is expected to close in August — mid-fiscal year. Their year-to-date SR&ED activity is significant: $400K in qualifying wages. Instead of waiting for the deal to close and triggering a deemed year-end at the lower rate, their tax counsel recommends accelerating the close of a prior-year claim (for the year ending December 31 of last year) before the August close date, and filing a stub-period return covering January to August for the current year — locking in the CCPC rate on the YTD qualifying work. The timing decision preserves approximately $85,000 in refundable credits that would otherwise become non-refundable.

Why this never comes up in due diligence

In most startup acquisitions, the SR&ED credit position is not a primary focus of due diligence. M&A counsel is focused on IP ownership, employment contracts, regulatory approvals, and representations about financial statements. Tax due diligence often focuses on liabilities — outstanding assessments, potential reassessments, transfer pricing exposure — not on tax assets that might be recovered differently post-close.

The founder often doesn't raise it because they don't know what questions to ask. And the acquirer often doesn't raise it because they're thinking about the business, not the Canadian tax credit program.

The result: founders walk into acquisitions without understanding that their CCPC status is expiring and that they have a narrow window — between LOI and close — to file outstanding claims and lock in the refundable rate on work already done.

If you're in a process right now

Pull your SR&ED filing history. Identify any fiscal years where work was done but a claim hasn't been filed yet. Check whether those years are still within the 18-month window. If yes, and if your company is still a CCPC, filing those claims before a control change preserves the refundable rate. After close, that option is gone.

The LOI period is not the time to start documenting R&D for the first time. If the evidence base doesn't exist — because the engineering team was heads-down and never tracked their investigation systematically — there's no realistic way to build it before close. The founders who capture the most SR&ED value in an acquisition context are the ones who were filing annually and documenting continuously before the conversation ever started.

This guide is for general information only. SR&ED credit treatment in acquisitions and mergers depends on specific transaction structure, timing, filing history, and applicable tax law. Founders engaged in M&A processes should obtain specific advice from a qualified Canadian tax lawyer and CPA before closing any transaction. Learn more at sredy.io.
