SR&ED enhanced 35% refund now covers first $6M of R&D spend

Canada's Budget 2025 raised the expenditure limit for the enhanced 35% refundable SR&ED tax credit from $3 million to $6 million of qualifying R&D spending per year (a two-step increase, first to $4.5M then $6M), applying to taxation years beginning on or after December 16, 2024. A qualifying Canadian-controlled private corporation (CCPC) can now claim up to about $2.1 million per year as refundable cash back on eligible R&D. The budget also extended access to the enhanced 35% rate to certain Canadian public corporations.

Why this matters for founders

For an incorporated Canadian founder doing product or technical R&D, this roughly doubles the refundable cash you can pull from SR&ED even before turning a profit, since the enhanced credit is refundable from year one. Track eligible salaries, contractor costs, and materials carefully and file the SR&ED claim with your T2 to capture the larger refund.
