Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment has she made of the potential impact of the patent box tax relief on levels of private sector (a) investment and (b) innovation.

HMRC published an evaluation of the Patent Box in 2020. The evaluation concludes that the Patent Box has had a positive impact on investment by companies, with an increase of around 10% in assets held by companies that use the Patent Box compared to similar companies that do not use the Patent Box since it was introduced.
