On 26th November 2025, Chancellor of the Exchequer, Rachel Reeves, announced a new ‘Mansion Tax’ for properties valued over £2 million in England.
The annual charge will be added on top of the existing council tax and will increase depending on the value of the property, with four separate bands.
At Myerson, we are alive to how this tax could initially unsettle our high-net-worth client base who own properties in Trafford and beyond but would like to stress that it is ‘likely to impact less than 1% of properties in England’ and most will be in concentrated in London and the South East.
In fact, we are taking an optimistic view that the announcement could pave the way for an upturn in the residential property market, for example, older homeowners downsizing.

What will the ‘Mansion Tax’ look like?
From 2028, if your property is worth more than £2mn, you will be subjected to the ‘Mansion Tax’ on top of your existing council tax.
The tax will differ depending on the value of your property and will be determined by the following four bands:
- £2 million to £2.5 million– You will pay £2,500.
- £2.5 million to £3.5 million– You will pay £3,500.
- £3.5 million to £5 million – You will pay £5,000.
- More than £5 million - You will pay £7,500.
While the charge will be imposed on top of the existing council tax, the money will go to the Treasury rather than the local authority.
Your property value will be determined by the Valuation Office Agency in 2026.
What is the purpose of the ‘Mansion Tax?’
In short, Rachel Reeves aims to use it as a vehicle to solve a ‘longstanding source of wealth inequality’’ in England.
According to the Office for Budget Responsibility, the ‘Mansion Tax’ will raise £0.4 billion in 2029 – 2030, which can then be used to assist the central government.
How does the ‘Mansion Tax’ differ from Stamp Duty Land Tax?
It is fundamental to note that these are two separate taxes.
Despite the widespread speculation about incoming stamp duty land tax changes in the 2026 Budget, the rates remain the same.
The key difference is that the ‘Mansion Tax’ will only affect homeowners with properties worth more than £2 million, whereas Stamp Duty Land Tax is a lump-sum tax paid on property purchases based on their value.
Stamp Duty Land Tax is a personal tax, and the duty payable will depend on your specific circumstances.
