Green Party Calls for 38% Windfall Tax on Big-Bank Profits to Fund SMEs

Policy Proposal and Financial Targets
The Green Party of England and Wales announced a plan to levy a 38% windfall tax on the domestic profits of the UK’s largest banks that exceed £800 million. The party cites campaign group Positive Money, which estimates the levy could generate about £19 billion a year. The revenue would be directed to small and medium-sized enterprises (SMEs) by doubling the Employment Allowance, potentially reducing National Insurance bills by up to £10,500 per business and providing a “lifeline” to more than one million SMEs.
Rationale and Context
Party leader Zack Polanski argues that record-breaking bank profits stem largely from high Bank of England interest rates intended to curb inflation, rather than from improved services or products. The proposal follows a similar idea floated last year, which the trade body UK Finance said was unnecessary because banks already pay a corporation-tax surcharge and a separate bank levy.
Industry and Political Reactions
The London Economic notes that Barclays reported a profit surge in the first half of 2026, with executive bonuses rising by nearly 30%, underscoring the Greens’ claim of “obscene” payouts. A Labour Party spokesperson countered that the government is already pursuing a “high-street renaissance,” citing measures such as business-rate cuts for roughly 32,000 small firms, devolved powers to support local hiring, and reduced transport costs. The spokesperson also described the Green proposal as “unrealistic” and “unfunded.”
Expected Impact on Small Businesses
If implemented, the tax-derived funds would allow SMEs to cut National Insurance contributions by up to £10,500, effectively lowering operating costs and potentially enabling the hiring of additional staff. The Greens present this as a direct boost to community economies, positioning the tax as a redistribution of excess bank earnings toward grassroots employment.
