There’s been a lot of talk recently about the new mansion tax announced in the Autumn Budget. While it won’t affect most homeowners, we know many people still have questions about what it means and how it will work.
At Rush Witt & Wilson, we’re keeping a close eye on the details so we can give clear advice as more information becomes available.
What is the mansion tax?
The mansion tax is a new yearly charge for homes in England worth £2 million or more. It will start in April 2028, but the values used to decide who pays will be based on 2026 valuations from the Government’s Valuation Office Agency.
Only a small number of homes in England are worth this much. According to the Government, less than 1%. But importantly, most of these are in London and the South East, an area where we work
How much will it cost?
There will be four price bands. So far, the Government has shared the following:
- £2m to £2.5m: £2,500 a year
- £2.5m to £3.5m: £3,500 a year
- £3.5m to £5m: £5,000 a year
- £5m+ : £7,500 a year
This charge is on top of the council tax that homeowners will still be required to pay. And unlike council tax, the money goes to the Treasury instead of the local council.
Who will have to pay it?
Homeowners, not renters, will pay the mansion tax. If you rent a property worth £2m or more, you won’t be the one paying the tax. Although rents could change over time as Landlords look to recoup this cost.
When does it start?
The tax begins in April 2028, but the key valuations occur in 2026. And these valuations will be reviewed every five years.
So, for now, no one needs to pay anything. But it’s something owners of higher-value homes may want to keep in mind over the next couple of years.
What about stamp duty?
Some people expected stamp duty changes in the Budget, but none were made.
The mansion tax is not the same as stamp duty.
Stamp duty is paid once when you buy a home, while the mansion tax is a yearly charge for homes over £2m.
Why is it called the “mansion tax”?
The name suggests it’s only for huge, luxury homes. But in places like the South East and London, a £2m property isn’t always what most people think of as a “mansion”.
The aim of the tax is to target the very top end of the market, but it may still affect long-term homeowners who bought many years ago and have seen their property value rise over time.
What if someone can’t afford to pay?
The Government has said there will be a support scheme for people who are “asset rich but cash poor”.
This may include options to delay the payment until the property is sold or the owner passes away. The government has said details will be shared next year.
Could the tax affect the market?
It might. And some possible changes include:
- Homes just above £2m may see pressure on prices
- Buyers might shift their focus to properties under the threshold
- Some owners could choose to downsize
- The higher-end market may slow slightly as people consider the extra yearly cost
But it’s still early days, and the full impact won’t be clear for some time.
What does this mean for you?
For most homeowners, nothing changes.
For those buying or selling a property worth £2m or more, this is something to be aware of, but remember, we’re still waiting for all the details.
