Monetizing Innovation: How to Claim Up to 65% in Combined Refundable R&D Tax Credits

For most of its history, the SR&ED program capped its enhanced 35% refundable federal credit at the first $3 million of qualifying expenditures for CCPCs. Effective for taxation years beginning on or after December 16, 2024, that ceiling doubled to $6 million, the single largest expansion the program has seen in more than a decade[1]. Combined with provincial credits that stack independently on top, the maximum theoretical recovery rate in Canada's most generous jurisdiction now approaches 65% of eligible R&D wages[2].

The Federal Base: What Changed

The current federal structure gives Canadian-controlled private corporations a 35% refundable investment tax credit on qualifying SR&ED expenditures up to the enhanced limit, now $6 million, with a 15% non-refundable credit applying to spending above that threshold[4]. The phase-out range tied to a corporation's taxable capital has also widened, giving more mid-sized, scaling companies access to the full enhanced rate before it begins grinding down[5]. Non-CCPC claimants and larger corporations continue to receive the base 15% rate, partially refundable in some circumstances[5].

Capital Expenditures Are Eligible Again

Capital expenditures on equipment and machinery used for R&D had been excluded from SR&ED eligibility since 2012. As of the December 2024 changes, they are eligible again, a meaningful shift for manufacturing, life sciences, and hardware companies whose R&D work is inherently equipment-intensive rather than purely wage-driven[1].

Province-by-Province Stacking

Combined rates are theoretical maximums for CCPCs within the enhanced expenditure threshold; some provinces reduce their credit by other government assistance received. Confirm your specific rate before modeling a claim[6].

Quebec's CRIC, which consolidated eight previous provincial R&D credits into one program for taxation years beginning after March 25, 2025, offers a base refundable rate of 20% with an enhanced 30% rate on the first $1 million of qualifying expenditures above the exclusion threshold, now available to all eligible corporations regardless of asset size[7]. Alberta's Innovation Employment Grant works differently from a standard tax credit stack: it pays 8% on spending up to a company's historical baseline, then 20% on incremental spending above that baseline, specifically rewarding companies that are growing their R&D investment year over year[8].

A Worked Example Across Three Provinces

Consider a CCPC spending $500,000 on eligible R&D salaries. In Quebec, combined federal and CRIC credits can return up to approximately $245,000 in cash[9]. The identical spend in Ontario, layering the federal credit with the OITC and ORDTC, produces roughly $175,000 to $210,000 depending on the proxy overhead method applied[4]. In a flat-stacking province like Manitoba or Nova Scotia, the same spend returns approximately $250,000 at a combined 50% rate. The underlying work, the underlying wages, and the underlying risk are identical in all three scenarios, only the province changes the outcome.

The New 90-Day Pre-Approval Process

Historically, SR&ED claims took anywhere from six to eighteen months from filing to receipt of credits. A new pre-approval process introduced in 2026 targets a 90-day turnaround specifically for claims that clear an early technical pre-screening, while complex claims or those selected for full technical review continue to take longer[10]. This makes early, well-organized documentation more valuable than ever, since a clean, pre-approvable file can meaningfully compress the time between spending the money and getting it back.

Why AI and Machine Learning Claims Face Extra Scrutiny

CRA has meaningfully increased scrutiny specifically on claims involving artificial intelligence and machine learning work, and documentation quality, not eligibility itself, has become the primary trigger for technical review on these files[10]. Because so much modern software work now touches AI tooling in some form, claimants need to be more precise than ever about isolating the genuine technological uncertainty in their own work from the routine application of existing, well-documented AI frameworks and libraries.

The 18-Month Filing Deadline

SR&ED claims must be filed within 18 months of the corporation's fiscal year-end, a firm, non-negotiable deadline. Missing it does not delay the claim, it eliminates it entirely, with no late-filing mechanism available[3]. This is precisely why contemporaneous, real-time documentation matters more than a well-written narrative assembled from memory eighteen months later.
