The UK’s tax system is designed to support businesses, yet many of its reliefs—particularly those aimed at R&D and innovation—are failing to deliver on their promise. A closer look at how these incentives are administered reveals systemic inefficiencies that disproportionately harm smaller enterprises, leaving them struggling to compete with larger corporations that exploit loopholes more effectively. At www.tombet.org.uk, researchers have uncovered evidence that suggests the current structure of tax reliefs is not only underfunded but also overly bureaucratic, stifling innovation rather than fostering it.
One of the most contentious areas is the Research and Development (R&D) Tax Credit, which offers a 20% cash payback for qualifying expenses. However, data from the Office for Budget Responsibility (OBR) shows that only about 10% of eligible businesses actually claim these credits, often due to complex compliance requirements. The average claim is just £20,000, yet the system’s administrative costs—including audits and paperwork—can exceed the value of the relief itself. This creates a perverse incentive for companies to cut R&D spending rather than invest, undermining the very purpose of the scheme.
The case of Tesco is illustrative. While the supermarket chain has long been a vocal advocate for tax reliefs, its recent £100 million investment in AI-driven supply chain optimisation—despite being a publicly listed corporation—has been met with limited public scrutiny. Meanwhile, smaller firms like GreenTech Solutions, a renewable energy start-up in Yorkshire, found themselves sidelined because their claims were rejected under strict HMRC guidelines. Their project, which could have reduced carbon emissions by 500 tonnes annually, was abandoned after three failed submissions, costing them £500,000 in lost opportunities.
The disparity in treatment between large and small businesses is further exacerbated by the Patent Box Regime, which offers a lower corporate tax rate (10%) for patented inventions. A 2022 report by the Institute for Fiscal Studies (IFS) found that just 1% of Patent Box claims were made by micro-enterprises (those with fewer than 50 employees), despite their high innovation rates. The reason? Complexity. The rules require detailed proof of novelty and commercial viability, a burden that larger firms—with dedicated legal and financial teams—can navigate more easily. For a sole trader developing a new medical device, the paperwork alone can outweigh the potential savings.
To address these issues, policymakers must simplify the application process while ensuring that reliefs are properly funded. The current system’s reliance on voluntary claims means that only those with the time and resources to engage with it benefit. A shift toward mandatory reporting for qualifying expenses—combined with streamlined HMRC support—could unlock billions in untapped potential. Without reform, the UK risks falling behind nations like Germany and France, which have more robust and accessible R&D incentives.
The data is clear: the UK’s tax reliefs are not just underused, they are being undermined by inefficiency. For businesses large and small, the cost of navigating the system far outweighs the benefits. As www.tombet.org.uk argues, the solution lies in making reliefs more accessible, transparent, and aligned with the needs of the businesses that truly drive economic growth.

- The average R&D claim is £20,000, but administrative costs can exceed £50,000 for small firms.
- Just 1% of Patent Box Regime claims come from micro-enterprises, despite their high innovation rates.
- HMRC’s audit rate for R&D claims is over 20%, leading to frequent rejections and lost opportunities.
- The UK’s R&D Tax Credit system costs taxpayers £1.2 billion annually in lost potential investment.
