Glossary+−
- Eligible Expenditures
Expenses that meet CRA SR&ED definitions and can be claimed for the SR&ED tax credit (labour, materials, certain contracts, and overhead allocations).
- Refundable Credit
A tax credit that is payable to the claimant even if there is no tax owing, subject to program rules and limits.
- Non‑Refundable Credit
A tax credit that can reduce tax payable but will not be refunded if it exceeds tax owing.
Key takeaways
This estimator helps project SR&ED tax credits by multiplying eligible expenditures by selected federal and provincial rates.
Always verify eligibility and current rates with CRA and provincial guidance before relying on estimates for decisions or filings.

Worked examples
Example: Small CCPC with $100,000 qualifying costs
A Canadian‑controlled private corporation submits $100,000 of qualifying SR&ED expenditures. Using a federal refundable rate of 35% and no provincial top-up, the estimated federal credit is $35,000 (100,000 × 0.35).
Interpretation
Estimated federal credit: $35,000; estimated provincial credit: $0; total estimate: $35,000.
Example: Non‑CCPC corporation with $50,000 qualifying costs and a provincial top-up
A non‑CCPC claims $50,000 of qualifying SR&ED costs. Using a federal rate of 15% and a provincial top-up rate of 5%, the estimated federal credit is $7,500 and the provincial credit is $2,500, for a combined estimate of $10,000.
Interpretation
Estimated federal credit: $7,500; provincial credit: $2,500; total estimate: $10,000.
