Get Up to 9x More R&D Tax Relief — Powered by Proven Experts
Most general accountants don’t have the time or specialist knowledge to uncover your full R&D tax credit potential — which could mean missing out on what you’re truly entitled to.
That’s where we come in. Claimly connects you with hand-picked R&D tax specialists who manage both the technical and financial details of your claim — ensuring every eligible activity is captured and compliant.
Our trusted partners know exactly how to maximise relief while staying in line with HMRC guidelines. Businesses referred through Claimly often recover significantly more than when using generalist advisors or going it alone.
Which R&D tax scheme applies to my company?
As of April 1, 2024, the UK government introduced a new, merged R&D tax credit scheme for accounting periods starting on or after that date. This reform replaces the separate schemes previously available for SMEs and large companies, with the goal of simplifying the process.
Under the merged scheme: All companies, regardless of size, now fall under a single 20% R&D tax credit rate. R&D-intensive SMEs (those spending over 30% of total expenditure on R&D) may still be eligible for an enhanced 27% tax credit if they are loss-making.
It’s important to note:The merged scheme applies only to accounting periods starting on or after April 1, 2024.Claims for earlier periods may still follow the SME or RDEC scheme rules and can be backdated for up to two years — meaning these legacy schemes remain relevant until April 2026.
Need help navigating these changes? Claimly can connect you with an R&D tax credit specialist who can assess your eligibility and explain your options in detail.
