Chancellor John Healey's first Budget on 28/10/2026 promises fireworks, with reports pointing to a sharp rise in the bank corporation tax surcharge as the star revenue-raiser. Amid Iran conflict-driven inflation and a £24.5bn September deficit, this move could fund vital cost-of-living breathing space without breaching Labour's manifesto locks.
Pre-Budget Speculation on the Bank Surcharge
Speculation swirls around reversing the surcharge from 3% back toward 8%, potentially raising over £2bn annually. This targets banks' bumper profits while sidestepping CGT hikes, income tax rises, NI increases or VAT changes. Funds may support energy and fuel relief or red tape cuts for households.
- Expected yield: £2bn+ per year
- Timing: Tied to OBR forecasts and fiscal headroom checks
- Political appeal: Hits banks, spares ordinary taxpayers
How the Bank Corporation Tax Surcharge Works
The surcharge applies to banks and building societies on taxable profits above a £1.5m threshold (adjusted for groups). It sits on top of the main 25% corporation tax rate. Currently at 3%, a return to 8% would push the effective rate to 33% for larger institutions.
This is fiscally attractive now due to strong bank profits and aligns with avoiding manifesto pledges. It is politically popular as it focuses on the financial sector rather than individuals.
