UK bank tax data before Budget

Highlights

UK Finance's PwC-backed claim that London's total bank tax rate is 46.2%—higher than Amsterdam, Frankfurt, Dublin and New York—faces criticism for excluding Paris.
A separate accountancy firm estimates Paris's bank tax rate at 51.6% to 57.3%, up to 11.1 percentage points higher than London, challenging the lobby's portrayal.
Campaign groups argue the exclusion may overstate London's tax burden, with the TUC claiming raising the bank surcharge to 8% could generate 2.25 billion pounds annually.

Disputed tax comparisons before the budget

As reported by The Guardian, UK Finance has been promoting annual PwC analysis that puts London’s total tax rate for a large bank at 46.2%, above Amsterdam at 42.2%, Frankfurt at 39.1%, Dublin at 29% and New York at 27.9%. The lobby group has used the figures in its case to ministers, warning that higher taxes could push jobs and business toward competing financial centers.

That comparison is now facing criticism because it does not include Paris, one of London’s main rivals for investment banking activity. Calculations reviewed by a leading accountancy firm indicate the same bank in Paris would face a total tax rate of between 51.6% and 57.3%, potentially up to 11.1 percentage points above London.

UK Finance says Paris is not omitted because of its tax position, but because it could not produce a robust like-for-like figure using the report’s model bank. The group also says the five cities in the study remain unchanged to preserve consistency over time.

Political pressure and sector implications

Campaign groups including the Trades Union Congress and Positive Money argue the exclusion weakens the industry’s case against a bank tax increase at the budget. They say the figures risk overstating London’s relative tax burden at a time when lenders are reporting strong profits and trying to limit the impact of fresh levies.

Paul Nowak, general secretary of the TUC, says some in the finance lobby are cherrypicking jurisdictions to support their argument and that Britain’s banks should pay a fairer share while households remain under pressure. The TUC says reversing earlier cuts and lifting the bank surcharge from 3% to 8% could raise 2.25 billion pounds a year.

Bank executives are sending mixed signals as the budget approaches. Barclays chief executive CS Venkatakrishnan says the hit from higher bank taxes would be bearable, while JPMorgan chief Jamie Dimon has warned previously that a more hostile tax environment could threaten investment and jobs, including plans tied to a new London headquarters. A Treasury spokesperson says decisions on tax remain for the chancellor to set out at fiscal events and declines to comment on speculation or proposals.

Draghi’s warning about the policy trade-off between inflation control, debt sustainability, and long-term growth highlighted how aggressive tightening and fiscal retrenchment can suppress the investment needed for productivity and resilience. Our earlier article noted his call for central banks to keep rates no higher than necessary for price stability, while governments support growth through measures like EU market integration and targeted industrial policy to de-risk investment.
