Large companies (and certain SMEs) can claim a Research and Development Expenditure Credit (RDEC). This R&D Tax Credit is available for businesses working on projects that make an advance in science or technology.
From 1 April 2020 to 31 March 2023, the RDEC rate was 13% of eligible R&D expenditure. From 1 April 2023, the RDEC rate rose from 13% to 20%.
Large companies, and SMEs unable to claim under the SME R&D Scheme, can generally apply for RDEC benefits. Companies are classed as large if they:
○ Employmore than 500 people;
○ Have a turnover of more than €100m and a balance sheet of more than €86m.

They have the skills to identify all eligible expenses, ensuring that no opportunities to claim back R&D expenses are missed.

Qualifying R&D expenditure for the RDEC scheme might include staff costs; subcontracted R&D costs; software, cloud computing and data licences; externally provided workers (EPW) and even consumable items used in the R&D process.However, identifying these costs can often be complex and nuanced. That’s where our team’s experience becomes invaluable. Our experts, with their deep understanding of the legislation and practical field experience, will identify all potential qualifying expenditures. This ensures you’re claiming for every eligible cost, maximising the financial benefits you receive.Find out if you qualify today >
