UK finance minister Healey weighs wealth tax options ahead of October budget

Britain’s Chancellor of the Exchequer John Healey is actively exploring wealth-targeted tax measures as he prepares for his first budget on October 28, a move that could reshape the fiscal landscape for the country’s wealthiest residents.

The deliberations come as Prime Minister Andy Burnham’s government faces a familiar squeeze: borrowing costs are climbing, and spending commitments on social care and defense keep growing.

What’s on the table

No formal proposal for a new annual wealth tax has been confirmed.

Campaigners from Oxfam and Tax Justice UK have been pushing for a 2% annual levy on assets exceeding £10 million. Research from the University of Warwick estimates such a tax could generate roughly £24 billion per year.

The Institute for Fiscal Studies has already flagged one of the most stubborn obstacles: figuring out what wealthy people’s stuff is actually worth. Publicly traded shares have clear market prices. A private business, a collection of rare art, or a sprawling agricultural estate? Those valuations get messy fast.

Burnham’s broader tax fairness agenda

Prime Minister Burnham has repeatedly signaled his belief that wealth is undertaxed relative to labor in the UK. He previously backed a high-value council tax surcharge targeting homes valued above £2 million, set to take effect in 2028.

Healey was appointed Chancellor in July 2026, giving him only a few months to navigate these crosscurrents before his budget debut.

The implementation puzzle

Annual wealth taxes exist in a handful of countries, including Norway and Spain, but nowhere at the scale being discussed in the UK.

The core problem is liquidity. A billionaire whose wealth is tied up in a private company doesn’t have £20 million sitting in a checking account to pay a 2% annual levy.

The IFS has been particularly pointed on this issue, noting that the valuation complexities surrounding private business assets could undermine the entire framework.

A £10 million threshold would capture a relatively small number of households, perhaps a few tens of thousands.

What to watch as October approaches

The £24 billion annual revenue figure cited by campaigners should be treated as an upper bound, not a forecast.

More probable near-term measures could include reforms to capital gains tax, inheritance tax, or pension tax relief for high earners. These are politically easier to implement because the administrative infrastructure already exists and avoid the valuation quagmire that makes a pure wealth tax so challenging.

For markets, high-value real estate in London could face pricing pressure as wealthy owners factor in potential new tax liabilities.
