UK Chancellor Eyes New Bank Taxes as Sector Reports Record Profits

Budget Pressure on Banking Sector

Chancellor John Healey is preparing to increase taxes on banks ahead of the upcoming Budget announcement in two weeks, according to conversations with senior banking executives. Despite previously describing banks as part of the UK economy's crown jewels, Healey appears ready to target the sector for additional revenue. The four largest banks collectively earned approximately £15 billion in profit during the first half of this year, prompting trade unions and government officials to scrutinize whether they should bear a larger tax burden.

Current Tax Structure and Revenue

The UK's largest banks and building societies currently operate under a layered tax system. They pay corporation tax at the baseline rate of 25%, plus an additional 3% surcharge specific to the banking sector. Beyond that, they also pay a separate levy based on the size of assets held on their balance sheets. Last year, this system generated substantial revenue for the Treasury: the bank levy alone contributed £1.4 billion, the surcharge added £1.2 billion, and when combined with income tax from bank employees, the sector contributed nearly £40 billion to government coffers.

Potential Tax Increase Options

Several mechanisms exist for increasing bank taxes. The most straightforward option would be restoring the surcharge to its previous level of 8%, down from the current 3%—a change implemented under former Chancellor Rishi Sunak when corporation tax rose from 19% to 25%. This restoration could generate approximately £2 billion annually. Alternatively, the levy itself could be restructured; it currently charges 0.1% on short-term loans and 0.05% on longer-dated obligations, with mortgages excluded from calculations.

A third approach, discussed with Treasury officials, involves restricting banks' ability to offset historical losses against current profits. This practice has particularly benefited Lloyds, which has used substantial losses from the 2008 financial crisis to reduce tax bills for over a decade. A temporary moratorium on this offset practice could yield around £1 billion per year while potentially being more palatable to the sector than outright surcharge increases.

The Competitiveness Debate

Banking industry representatives have mounted significant opposition to tax increases. UK Finance, the sector's trade body, warned that additional taxes would diminish competitiveness, discourage investment and employment, and undermine the government's growth objectives. JP Morgan Chief Executive Jamie Dimon has specifically cautioned that the UK already imposes one of the world's highest tax burdens on banks, and further sector-specific levies could drive investment away.

However, this argument faces pushback from multiple quarters. Sir Philip Augar, a former City banker and author, contends that banks currently enjoy exceptionally favorable conditions due to higher interest rates, which have widened the gap between lending rates and savings rates, boosting profitability. He argues there is room for a moderate tax increase raising up to £3 billion annually without harming growth. Augar also highlighted the philosophical inconsistency: banks expect government bailouts during crises yet resist taxation during boom times, claiming they cannot simultaneously be too big to fail and too big to tax.

Union Support and Political Dynamics

Trade unions have actively called for higher bank taxation. Paul Nowak, general secretary of the Trades Union Congress, acknowledged that most bank workers are not wealthy executives, but nonetheless endorsed asking banks to pay a fairer share of tax if the chancellor pursues this in the Budget. This position reflects broader political appetite for addressing the banks' substantial recent profits through the tax system.

The political sensitivity around this issue relates partly to the banks' relief at avoiding taxation in the previous Budget, despite their significant earnings. The fact that banking executives are now confirming tax increases are on the table suggests the government has signaled this outcome is likely. Industry leaders face a strategic challenge: any tax measure hitting UK banks while exempting foreign banks' UK operations would be difficult to justify alongside government rhetoric about supporting British business.
