The chancellor announced a mansion tax in the budget, saying it would solve a "long-standing source of wealth inequality".

-
What it is: The UK government introduced a High Value Council Tax Surcharge (often described as a mansion tax) targeting homes valued above £2 million, with four fixed annual bands. The charges start at £2,500 for properties £2m–£2.5m and go up to £7,500 for £5m+, uprated annually with CPI inflation. This policy is designed to raise additional revenue and address wealth inequality, with the revenue earmarked for central government rather than local councils.

Implementation timeline: The surcharge is set to apply from 2028, following a government consultation and a valuation exercise to identify eligible properties. The plan envisions revaluations at five-year intervals. [Sky News coverage; MoneyWeek overview][3][1]

Scope and impact: The measure is expected to affect a small share of properties (the examples cited generally target the top 0.4%–1% of homes by value, concentrated in London and the Southeast). The government emphasizes protections for low-income households and possible deferral/support options, but acknowledges potential market distortions as owners may seek to downsize or alter listed prices to avoid the surcharge.
