Stacking Recommendation & Action Plan
How to optimize your filings by leveraging both programs in parallel.
Yes, you can and should stack IRAP and SR&ED! This is the single highest-yielding strategy for Canadian software and hardware startups.
The stacking workflow operates as follows:
- Step 1: Apply for the IRAP wage grant to cover up to 80% of your primary developers' salaries during the active development period.
- Step 2: At your fiscal year-end, claim the SR&ED tax credit on all remaining eligible expenditures.
- Step 3 (The Grind): When compiling your SR&ED claim, you must declare the IRAP funding received as "assistance." CRA will deduct (grind) the IRAP amount from your qualified pool, but you will still claim tax refunds on the remaining 20-50% of wages that were paid out-of-pocket.
