Patent Box scheme: what is it and how to claim
5 Mar 2026 • Business Tax • Innovation Incentives
Written by
Patent Box is a government incentive designed to encourage companies to retain and commercialise intellectual property in the UK. It applies a reduced tax rate to profits derived from patented products, processes, or licensing. But many businesses miss out on this incentive either through issues with their company structure or having the wrong IP protections. In this article we outline how the Patent Box scheme might work for your business.
How does Patent Box work?
Eligible companies will pay a lower rate of just 10% on their patent box profits, compared to the main corporation tax rate of 25%. The benefits of the scheme can be substantial for more lucrative corporations, and businesses with high-margin products. However, the calculation can cause complications that will reduce the benefits obtained. We work with businesses to identify the potential tax benefits of using this incentive, by modelling their product and value streams.
Profits attributable to the IP | £500,000 | £1,000,000 | £1,500,000 |
25% Corporation tax due on the IP profits |
Who is eligible to claim the Patent Box scheme?
To qualify, your company must:
Be a UK-based limited company paying UK corporation tax
Own or exclusively license a granted patent awarded by the UK Intellectual Property Office, the European Patent Office, or a designated EEA nation
Have been involved in the development of the patented invention
Generate trading profits from the patented invention
How to claim
If claiming for the first time, you must make an election into the Patent Box system within two years of the relevant accounting period in which relief is sought. A company can elect early, before a patent is awarded, to claim tax reduction on qualifying revenues earned between the filing of the patent application and the grant of the patent - the patent pending period. The accumulated relief is claimed in the year the patent is awarded on the tax return. After this point, the patent box scheme follows the normal corporation tax rules allowing amendments to be made up to two years after the end of the qualifying accounting period.
It is always worth modelling any claim ahead of electing to the scheme to allow IP to be moved or restructured to avoid losing out on any potential benefits. For first time claimants this process can be complex, and we can help with ensuring the correct splits are made and allocating costs to the correct parts of the calculation. We offer a modelling service to plan out patent box submissions to support this process.
