Fears are mounting within the UK banking sector over a potential fresh tax raid as Chancellor Rachel Reeves prepares for the upcoming Budget next month. According to a recent report by trade body UK Finance, the industry already shoulders significantly higher tax burdens than major financial hubs such as New York and Frankfurt, a reality that risks sending a “negative signal to international investors.”

UK Finance’s 2025 banking sector tax report reveals that banks based in London face a total tax rate of 46.4%, surpassing Amsterdam at 42.2%, Frankfurt at 38.9%, Dublin at 28.9%, and New York at just 27.9%. This increase is mainly driven by changes to employer National Insurance Contributions (NICs) implemented in April 2025, with projections suggesting the rate will rise further to 46.6% by 2026 as the full impact takes effect. The report states that banks contributed £43.3 billion in tax for the financial year ending March 2025, accounting for approximately 4.3% of total UK government tax receipts.

The tax burden includes not only corporation tax and the bank levy, which alone brought in £23.1 billion, but also £20.2 billion collected through income tax and national insurance from bank employees. Unlike some global centres such as the US, Switzerland, and Singapore, the UK maintains permanent sector-specific banking levies, which have added to the cumulative tax load on the industry.

David Postings, chief executive of UK Finance, warned that ongoing uncertainty regarding future bank taxation and the permanence of these sector-specific levies may deter international investors. He emphasised, “A strong economy needs strong banks,” highlighting the sector’s vital contribution to public finances while cautioning against policies that could undermine growth. Barclays chief executive CS Venkatakrishnan echoed these concerns last month, pointing out the UK banks’ uniquely heavy tax burden and questioning how much more the sector can be squeezed.

The speculation about an imminent tax hike intensified earlier this month, with reports that Reeves is considering raising the banking surcharge from 3% to 8%, a move expected to generate an additional £2 billion. Moreover, a suggestion from the Institute for Public Policy Research to impose a windfall tax on lenders could raise up to £8 billion annually, though this has met resistance from industry leaders who argue such measures would restrict lending capacity to households and businesses.

Meanwhile, the Institute for Fiscal Studies (IFS) has urged the Chancellor to consider substantial tax increases as part of a broader strategy to stabilize the public finances. The IFS analysis highlights the need to raise around £42 billion via tax hikes and spending cuts to address Britain’s fiscal challenges and create a buffer for future uncertainty. However, Reeves faces political constraints, having pledged not to raise major personal taxes during the election campaign, and has abandoned welfare cuts due to internal party opposition. The IFS recommends reforming wealth and property taxes as alternatives, while some economists caution that heavy tax increases could exacerbate inflation and prolong the Bank of England’s high interest rate policy.

The banking sector’s call for relief from additional levies is underscored by UK Finance’s advocacy for phasing out the bank corporation tax surcharge and the bank levy altogether. They also push for scrapping the 0.5% stamp duty on UK share purchases, a move supported by the Investment Association despite debates over its actual impact on market demand. Banks and investment firms are simultaneously adjusting to new regulations requiring compensation to fraud victims, further complicating their financial landscape.

As lenders prepare to report third-quarter results next week, their leadership is expected to reiterate warnings about the detrimental effects of further tax increases on growth and lending capacity. Yet, some observers argue that the sizeable profits banks continue to post indicate they can sustain higher tax contributions. This tension highlights the delicate balance Chancellor Reeves must strike between shoring up public finances and maintaining the UK’s competitiveness as a global financial centre.
