John Healey Considers Lowering the Mansion-Tax Threshold to £1.5 million
By Drooid · · How we work
Core Proposal and Scope
The Treasury is debating whether to reduce the mansion-tax threshold from £2 million to £1.5 million. Under the current scheme, properties valued at £2 million-£2.5 million would pay an annual surcharge of £2,500, rising to £7,500 for homes above £5 million. Lowering the threshold would expand the levy from the 134,000 homes originally targeted to an estimated 271,000 households based on current valuations.
Background and Context
The “mansion tax” was introduced in the Autumn Budget last year by former chancellor Rachel Reeves, applying an extra charge to high-value homes as a wealth-tax measure. The government now faces a fiscal gap of roughly £10 billion ahead of the upcoming autumn Budget, a shortfall it attributes in part to higher borrowing costs linked to the war in Iran. Reducing the threshold is being examined as one way to generate additional revenue while the Treasury seeks to balance the books.
Data and Statistics
- Original threshold (£2 million) – 134,000 homes affected.
- Proposed £1.5 million threshold – 271,000 homes affected, effectively doubling the levy base.
- Surcharge bands remain unchanged: £2,500 for £2 million-£2.5 million, up to £7,500 for properties over £5 million.
- Analysts estimate the change could raise about £800 million a year.
- Since the last budget, the number of homes valued above £2 million has fallen 6.5 percent as owners lower asking prices to avoid the tax.
Official Statements & Responses
The chancellor, John Healey, is reported to be seeking around £10 billion of additional revenue, but officials stress that no final decision on the threshold has been taken.
Verbatim Quotes
- “As has always been the case, decisions on tax are a matter for the Chancellor to set out at fiscal events, rather than routinely commenting on rumour, speculation or proposals.” — Alamy An HMT spokesperson
- “They’ve already got to cope with rising interest rates and energy costs and this could just be the straw that breaks the camel’s back.” — Lucian Cook, the head of residential research at Savills
- “The other risk is that people whose finances are stretched may find that they need to leave the property that they live in and are very emotionally attached to. That is one of the less palatable consequences.” — Arun Advani, the director of the Centre for the Analysis of Taxation
What’s Next
The Treasury has described the threshold discussion as “live,” and a decision, if any, is expected to be announced at the autumn Budget later this year. No formal policy change has been confirmed at this stage.
