Get Up to 9x More R&D Tax Relief With True Specialists — Not Just Accountants
Most accountants and tax teams don’t have the time or specialist knowledge to uncover your full R&D entitlement — and that leaves money on the table.
Unlike many R&D firms, our experts handle both the technical and financial aspects of your claim in-house. This ensures nothing gets lost in translation and every qualifying activity is fully accounted for.
We dig deeper, document better, and know exactly how to maximise your claim without triggering red flags with HMRC — which is why our clients often recover up to 9x more than those using generalist accountants or self-submitting.
Which R&D tax scheme applies to my company?
As of April 1, 2024, the UK government introduced a new, merged R&D tax scheme for accounting periods beginning on or after that date. This reform replaces the previous separate schemes for SMEs and large companies, aiming to simplify and streamline the R&D tax credit system.
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 more than 30% of total expenditure on R&D) can still benefit from an enhanced 27% tax credit if they are loss-making.
It’s important to note:
- The merged scheme only applies to accounting periods starting on or after April 1, 2024.
- Claims for earlier periods will still follow the old SME or RDEC scheme rules and can be backdated for up to two years — meaning those legacy schemes remain relevant until April 2026.
