JP Morgan CEO Warns Burnham Bank Tax Could Stall £3bn Tower 2026

JP Morgan CEO Jamie Dimon has issued a stark warning to Greater Manchester Mayor Andy Burnham, cautioning that higher bank taxes could jeopardize the bank's £3bn headquarters in London and drive investment away from the UK. In an interview on the Master Investor Podcast, Dimon said taxing banks 'may sound great' but carries 'adverse consequences' for shareholders and the broader economy.

Dimon’s Warning on Bank Tax Surcharge

The world’s largest bank already pays a 28% corporation tax rate—higher than the standard 25%—plus a separate levy on UK balance sheets. Dimon argued that penalizing banks disproportionately hurts a sector that contributes massively to jobs and growth. 'I would be very cautious if I was a government thinking that penalising any company out of the ordinary is a good thing for that country,' he said.

Impact on JP Morgan's London Headquarters

Dimon approved the 279,000 sq metre Canary Wharf tower last year after the banking industry was spared higher taxes in former chancellor Rachel Reeves’s autumn budget. However, he now warns the project—which would house more than half of JP Morgan’s 23,000 UK workforce—could be scrapped if Burnham’s government raises taxes. 'That’s a binary decision … I don’t know what I would do,' Dimon stated.

Key Takeaways from Dimon’s Interview

• Higher bank taxes risk derailing JP Morgan's £3bn Canary Wharf headquarters.
• The UK’s bank tax surcharge is already higher than the standard corporate rate.
• Dimon warned that penalizing banks could drive investment away from Britain.
• The bank CEO previously threatened to cancel the tower if a new Labour leader was hostile to banks.

Broader Implications for UK Business

Dimon’s comments come amid ongoing debates about how to raise revenue without stifling growth. The UK has one of the highest bank tax rates in the developed world, and industry leaders argue it undermines London’s competitiveness as a financial hub. As Prime Minister Keir Starmer’s government considers tax options, Dimon’s warning serves as a reminder of the delicate balance between fiscal policy and business confidence.
