R&D tax credits, explained
Research & Development Tax Credits are a UK tax incentive designed to encourage companies to invest in R&D. Companies can reduce their tax bill or claim payable cash credits as a proportion of their R&D expenditure. R&D Tax Credits can be claimed on development of a new product, process or service, or improvements to existing ones – even if the work wasn’t successful.

Are you eligible to claim?
R&D tax credits don’t just apply to white coat or laboratory based research. Companies in any industry may be eligible. Any work to improve a product, process or service, or even develop a new one, may be eligible – even if the work wasn’t successful. If this work required a scientific or technological problem to be solved that couldn’t have been resolved by a short conversation with competent professionals – some of the work probably qualifies as R&D.
If you’re not sure whether your work qualifies – contact us for a free consultation.

What costs can I claim for?
Staff costs for any time they spent on the R&D projects, including any National Insurance and Pension contributions.
65% of any costs related to freelancers or companies subcontracted to help with the Research & Development.
Consumable items, including any materials used within the R&D.
The cost of any software used as part of the R&D process.
The relevant proportion of water, fuel or power consumed as part of the R&D.

How much can I get back?
A profit making company can receive up to 25% of its Research & Development costs back. This will mean either a reduction of that value in your corporation tax bill, or a payable credit if you have already paid.
A loss making company can receive up to 33% of its Research & Development costs back. This will mean a payable credit from HMRC.
