R&D TAX RELIEF &
PATENT BOX

R&D tax relief presents the opportunity to recover a significant portion of your investment in innovative research, while Patent Box tax relief lowers the Corporation Tax rate on income derived from licensed patents.

Though these reliefs are enticing, claiming them can be intricate. Leveraging our expertise, we have a proven record of navigating the qualification process and securing successful R&D claims with HMRC, resulting in substantial tax savings for businesses. Similarly, we adeptly utilise Patent Box reliefs to diminish the effective tax rate on commercial transactions, ensuring our clients maximise returns on their intellectual property.
