Dimon warns UK against raising bank taxes amid fiscal pressure
In brief
- Dimon warned higher UK bank taxes could trigger capital flight from the country
- JPMorgan's £3 billion Canary Wharf headquarters may not proceed if tax environment becomes hostile
- UK banks currently pay 3% corporation tax surcharge on profits above threshold
- Surcharge was cut from 8% in April 2023 after 2008 financial crisis introduction
Capital flight and competitive disadvantage
Dimon's concern centers on the UK's corporation tax surcharge on banks. UK banks currently pay a 3% surcharge on profits above a set threshold, on top of the standard corporate rate. The surcharge was cut from 8% in April 2023 after being first introduced in the aftermath of the 2008 financial crisis.
Despite the reduction, Dimon cited a figure of $5 billion paid by shareholders as a result of the current surcharge regime. His core argument is straightforward: an uncompetitive tax system pushes capital elsewhere.
"If you have an uncompetitive tax system, capital leaves your country" — Jamie Dimon, CEO of JPMorgan Chase
The Canary Wharf project at risk
The CEO made clear that JPMorgan's investment plans are contingent on a favorable tax environment. A planned £3 billion JPMorgan headquarters in Canary Wharf may not happen if the tax environment turns hostile. For London, which has long competed with New York and other global financial centers, losing such an investment signals a broader erosion of competitiveness.
Dimon has raised the bank tax issue multiple times over the years since the surcharge was first introduced. His latest intervention arrives as the new Burnham administration faces pressure to shore up public finances. The tension is real: higher bank taxes could generate short-term revenue, but at the cost of deterring the very capital that sustains London's financial ecosystem and broader economic growth.
