UK R&D Tax Relief – an overview

  • A generous tax relief available to all eligible UK subsidiaries of US businesses (not just start-ups)
  • Available for businesses that are paying technical experts to solve technical problems – undertaking Product, Process, or Software development
  • Tax relief is worth between 10.53% and 33% of qualifying expenditure via Corporation Tax reductions, tax refunds, cash credits and the creation of additional tax losses– an unrivalled relief in the UK
  • Possible to recover a proportion of an equity investment or acquisition value via tax refunds or credits, for R&D work undertaken by the UK business

Getting your claim right is crucial, so it is advisable to partner with a reputable and technically expert UK R&D tax relief specialist that holds memberships with Professional bodies.

At Radius, we are passionate about going the extra mile for our clients and producing claims to the highest technical standard.

Our unrivalled approach takes away the burden of the claim process as we maximise the relief available within the parameters of the scheme. Radius are members of a select professional forum, which keeps us up to date with all policy and legislative changes, and allows us to help refine the R&D scheme itself. And our team includes an ex HMRC R&D Inspector to ensure our claims are robust and compliant with all current HMRC guidelines.

  • Tax savings for innovative UK businesses

    • Similar in benefit and operation to the R&D Tax Credit available to American companies, UK R&D tax relief is a significant tax break available to UK businesses. It is available to UK subsidiaries of American businesses, plus businesses with overseas private equity investment.
    • Long-established companies, along with start-ups across a range of sectors are eligible to claim.
    • The UK is one of the most innovative countries in the world, ranked fourth in the Global Innovation index. The government reinforces this by providing one of the most generous tax relief schemes available

    As members of the Praxity Global Alliance, Radius are here to help all businesses – whatever their global structure – claim their full entitlement of UK R&D tax reliefs. Many companies do not realise they qualify.

  • Who can benefit from this relief?

    The UK R&D Tax Relief scheme offers superb benefits to American businesses and private equity investors:

    • Are you an American business or private equity organisation with existing operations or subsidiaries in the United Kingdom?
    • Even early-stage businesses can benefit via cash-back tax credits for their initial R&D work.
    • Or are you looking to set-up a new company in the UK?
    • Are you an accountant, working with an American company or private equity investor that has operations or subsidiaries in the UK?

    Although R&D work may be carried out by a UK business, American businesses based in the United States that have, or are planning of having links to a UK business that carries out qualifying R&D work, could stand to benefit significantly from R&D tax relief.

Case study examples of qualifying R&D projects

Public safety software company

A new wave of solutions for event and venue management. The company claimed relief on their development of an advanced events management system, providing a real-time solution to improve the situational awareness and threat resolution systems already existing in the market.


Software claim

R&D carried out by the company involved the development of new platforms and features, including functionality to centralise import processes and replace manual processes, reconciling batches of data, as well as a platform to process payments.


Cyber security specialist

Development of products to prevent attacks on APIs. Working at the forefront of their field, the company faced uncertainties surrounding processing a variety of possible data types, structuring data in a specialised way whilst processing it quickly.


E-Learning platform

Designing a unique learning platform to keep track of training and skills development. This required the development of bespoke software infrastructure and testing, with uncertainties surrounding scalability, security, and accessibility across several devices.


Analysis process development

A company conducts ongoing R&D into the creation of separation processes for chemical compounds. A new process is required for each compound, depending on its proposed use, with an infinite number of potential variables.


Greater energy efficiency

A company aimed to reduce energy use whilst not compromising product performance of refrigeration units. This included streamlining areas so that air flow capacity would remain optimal, therefore reducing the level of power required to run the system.

  • Reduce Tax with Patent Box

    Similar to the R&D scheme, Patent Box Tax Relief allows UK businesses to pay a lower effective Corporate Tax rate of 10% on profits arising from patented products or services.

    This can apply where a UK business exclusively licences a patent, perhaps from an overseas group company.

    The Radius team includes dedicated Patent Box experts who have gained a unique specialism in these rules ever since their introduction in 2013. Our team submitted some of the very first claims to be made under the Patent Box tax relief regime, and we have saved clients millions of pounds in Corporation Tax since then.
