SR&ED Tax Credit: Is Your Canadian Business Leaving Money on the Table?

The Biggest SR&ED Change Since 2012

If your business does any form of research, development, experimentation, or technical problem-solving in Canada, there is a real chance you are sitting on an unclaimed tax credit worth tens or even hundreds of thousands of dollars—and the program just became significantly more generous. On March 26, 2026, Bill C-15 (the Budget 2025 Implementation Act) received royal assent, enacting what multiple major accounting firms are calling the largest enhancement to the SR&ED program in over a decade [citation:1][citation:4][citation:8].

The Scientific Research and Experimental Development (SR&ED) program is Canada's largest federal tax incentive supporting business R&D. Unlike a grant or a loan, SR&ED works through the tax system—delivering either a reduction in tax payable or, for many qualifying companies, an actual cash refund, even if the company owes no tax at all that year [citation:1][citation:3].

What Changed: The Headline Numbers

Effective for tax years beginning on or after December 16, 2024, three major enhancements now apply. These changes represent the most significant expansion of the program since it was restructured in 2014 [citation:3][citation:8][citation:10].

1. The Enhanced Expenditure Limit Doubled to $6 Million

The annual expenditure limit under which a Canadian-Controlled Private Corporation (CCPC) can earn the enhanced 35% refundable SR&ED investment tax credit increased from $3 million to $6 million. This means a qualifying CCPC spending the full amount can now claim up to $2.1 million annually in refundable credits, up from $1.05 million previously—effectively doubling the cash-back ceiling for growing, R&D-intensive small businesses [citation:1][citation:2][citation:4].

2. Capital Expenditures Are Eligible Again

This is arguably the most consequential change for hardware-intensive industries. Capital expenditures—equipment, machinery, apparatus, and related lease costs—had been excluded from SR&ED eligibility since 2014. That exclusion has now been reversed. Property acquired on or after December 16, 2024, intended to be used all or substantially all (90% or more) of its operating time performing SR&ED in Canada, is once again eligible for both the income deduction and the investment tax credit [citation:1][citation:3][citation:8].

For manufacturers, biotech companies, clean technology developers, and robotics firms—where specialized R&D equipment often represents the single largest cost component of an innovation project—this reverses what had been a meaningful gap in the program for more than a decade. An amount equal to 40% of capital expenditures on the acquisition cost of depreciable property used in SR&ED activity are eligible for the refundable ITC at the ITC rate of 35% [citation:2][citation:10].

3. Higher Phase-Out Thresholds and New Revenue Option

The enhanced 35% rate phases out as a CCPC's (or its associated group's) prior-year taxable capital grows. That phase-out range has moved from $10 million-$50 million to $15 million-$75 million—allowing mid-sized, scaling companies to retain access to the enhanced refundable rate considerably longer as their balance sheets grow [citation:1][citation:2][citation:4].

Additionally, CCPCs now have a genuinely useful new option: they can elect to use a gross revenue calculation instead of taxable capital to determine their expenditure limit phase-out—whichever method produces the more favourable result for their specific situation. This flexibility particularly benefits early-stage, capital-light companies that might otherwise phase out of the enhanced rate too early based on taxable capital alone, despite still having relatively modest revenue [citation:1][citation:2][citation:4].

A New Category of Eligible Corporation: ECPCs

For the first time, Eligible Canadian Public Corporations (ECPCs)—public companies that remain Canadian-resident and Canadian-controlled, with shares listed on a designated stock exchange—can now access the enhanced 35% refundable rate, something previously reserved exclusively for CCPCs [citation:1][citation:2][citation:4].

This addresses a long-standing structural problem: companies that went public to raise growth capital used to automatically lose access to this valuable refundable credit, forcing an uncomfortable tradeoff between raising capital and retaining R&D tax support. ECPCs get their own expenditure limit calculated using a three-year average gross revenue method, starting at the full $6 million limit and phasing down to zero as average revenue moves from $15 million to $75 million [citation:1][citation:2][citation:4].

What Actually Qualifies as SR&ED Work

The CRA evaluates eligibility against three core criteria, and genuinely understanding these—rather than assuming we built something new automatically qualifies—is where many claims succeed or fail: Scientific or technological uncertainty—the outcome could not be determined in advance using standard practice or existing knowledge. A systematic investigation—genuine experimentation, hypothesis formation, and testing, not simply trial-and-error tinkering without a structured approach. Scientific or technological advancement—the work generated new knowledge or capability, even if the underlying project ultimately failed commercially. Importantly, a project does not need to succeed commercially to qualify—SR&ED is specifically designed to support the uncertainty and experimentation inherent in R&D, including projects that are ultimately abandoned once the technical uncertainty is resolved (even when the resolution is this approach does not work).

The Filing Deadline: Absolute, With No Exceptions

This is the single most consequential deadline in the entire program, and it deserves to be stated plainly: failing to file your SR&ED claim within 18 months of your tax year-end forfeits the entire claim—permanently, with no extensions and no exceptions [citation:4]. Example: a corporation with a tax year ending December 31, 2025 must file its SR&ED claim no later than June 30, 2027. Miss that date by even a single day, and the credit—regardless of how legitimate or well-documented the underlying R&D work was—simply cannot be claimed. Given the severity of this deadline, the practical advice from SR&ED specialists is consistent: calendar the deadline immediately when your tax year closes, and begin the claims process 4 to 6 months before the actual deadline, not in the final weeks. Documentation gathered contemporaneously throughout the year is also significantly more defensible than reconstructed records assembled under deadline pressure.

Conclusion: Is Your Business Leaving Money on the Table?

SR&ED claims sit at the intersection of technical project documentation and tax filing precision, and the program's reputation for generating CRA reviews makes defensible, well-documented claims genuinely valuable. Consider professional guidance if your business is investing meaningfully in product development, engineering, or technical problem-solving and has never assessed SR&ED eligibility, if you have previously filed a claim for a tax year now affected by the 2026 enhancements, if you are planning capital equipment purchases for R&D purposes, or if you want help building contemporaneous documentation practices before your next fiscal year closes.
