How Much Will You Pay? Understanding the Mansion Tax Bands
The mansion tax is an annual surcharge paid in addition to your existing council tax. The government has created four fixed bands based on your property's 2026 market value:
Property Value (2026) | Annual Surcharge |
|---|---|
£2m – £2.5m | £2,500 per year |
£2.5m – £3.5m | £3,500 per year |
£3.5m – £5m | £5,000 per year |
Over £5m | £7,500 per year |
These charges will increase annually with CPI inflation and are collected through your local council, with revenue going directly to the Treasury.
