R&D Tax Credit Calculator
How are R&D Tax Credits Calculated?
R&D Tax Credits are worth 25% of qualifying expenditure. This rate applies to all companies subject to Corporation Tax and can be used to reduce your tax bill or refunded in cash over three years if your liability is low.
Qualifying costs include staff directly engaged in R&D, consumables such as materials and prototypes, subcontracted R&D (within limits), and certain data and cloud computing costs. Claims must be made within 12 months of your accounting year-end.
Our team ensures every eligible cost is captured and your documentation fully supports the claim, giving you peace of mind that it will stand up to Revenue review.

How much in R&D Tax Credits can my business claim?
Eligible companies can generally claim a 30% tax credit on qualifying R&D expenditure, rising to 35% for accounting periods beginning 1st January 2026. This credit can be used to reduce your corporation tax liability, or — if you don’t have enough profits — can be received as a repayable credit spread over instalments. When combined with the standard 12.5% tax deduction on R&D costs, the overall benefit can be significant.
