The Patent Box

By electing in to the Patent Box, an innovative company can achieve a significant long-term reduction in its corporation tax bill.

What are patent box tax incentives?

The Patent Box is a 10% rate of corporation tax that can be claimed by companies that have patented products, or processes, developed by the company. It is applicable to patent related profits and applies for the life of the patent, lasting up to 20 years.

Typical businesses claiming patent box reliefPatent box

According to the latest HMRC statistics (issued September 2021) only 1,405 claims were made in 2018-19 (the most recent accounting period on which full statistics are available).

The uptake of the Patent Box is disappointing, particularly as the tax savings from paying tax at 10%, compared to the normal 19% rate, over the whole life of the patent can be great.

Of the companies that claimed, over half were in manufacturing, including the pharmaceuticals.
