How to Combine Grants & R&D Tax Credits Without Losing Out

Working

Startups often assume that receiving a grant (from bodies like Innovate UK, Scottish Enterprise, Invest Northern Ireland or Enterprise Ireland) automatically disqualifies them from claiming R&D tax credits.

That’s a common misconception. While the interaction between grants and R&D incentives is complex, it’s entirely possible to access both, if you plan carefully.

Receiving a notified state aid grant, such as Innovate UK funding, does restrict your ability to claim under the SME R&D tax relief scheme for the same project. However, this doesn’t make you ineligible for R&D credits altogether.

Instead, costs relating to the grant-funded project may still qualify under the Research and Development Expenditure Credit (RDEC) scheme — a slightly less generous, but still valuable, alternative designed for larger companies or those in receipt of state aid.

Why This Matters

R&D tax credits can return up to 27% of eligible spend under the SME ERIS (Enhanced R&D Intensive Support) scheme, and around 15–16% under the new RDEC (merged) scheme. Without careful planning, you could miss out on significant cash credits or tax relief.

"By strategically planning your grant funding and R&D activities, you can ensure you don’t leave money on the table. It requires navigation, but with the right advice, both can work in your favour."
