Mansion Tax at £1.5m - what will this mean?

856 replies

MaureenOHara · 20/09/2026 09:27

Does anyone have any idea what this might mean for an individual and what it might do to the market. What happened to the £2m market and will that be replicated or is it different?

This “fortune” is irrelevant if it is all a notional value of the house that you live in because you cannot realise any of that supposed wealth unless you fancy living in a tent.

I agree wrt 'mansion' tax. I think it's a terrible idea for that and a number of other reasons, not least that the government and civil service is so completely incompetent that there is no way valuations will be completed fairly and equitably.

But I do get tired of the often-touted on this site narrative that 'people who live in the south are so screwed', when actually the creation of wealth via insane house price increases is a major benefit for many.

I don’t think you can means test the pension. What incentive is there to work in that case at all. I can see the arguments for getting rid of the triple lock as the intention was to raise it initially and it had its place in time and history. But means testing state pension? People will just think what next, state schools, NHS etc? They are already taking from those contributing the most financially. It will lead to the collapse of society if you remove all universal benefits.

"What incentive is there to work in that case at all."

To eat, to pay your big mortgage or rent for shelter?

I am often down south and understand the house price differential. Although southerners often fail to recognise in these conversations that a lot of them have benefitted from enormous growth in house prices, whereas people in the north generally have to more actively pay down their debt as house price increases are much more modest. So although I get the ‘my house is worth £1.5m but it’s just a terrace, it would buy a bigger house in the north’ complaint, ultimately they still have an asset work £1.5m and they have often benefitted from dramatic increases.

I know a lot of people in the south on modest incomes who have made a fortune in property, so to suggest that it is all hardship doesn’t quite show the whole picture. Obviously accepting that getting on the property ladder itself is more challenging these days.

The asset is only worth what someone will pay, it reduces as interest rates rise and also is reduced by tax policy like this, it is not like money in the bank, and to get cash from the house you would need to downsize or live with a relative or something?

Yes I understand that, and my earlier response confirms that I agree the 'mansion' tax doesn't work for this and other reasons. But the fact remains that there are a large number of people who have and are benefitting hugely from house prices in the south, whether they immediately liquidate the asset or not.

BeardySchnauzer · 21/09/2026 14:56

well there’s no way to avoid losing a chunk of your house value to tax at some point if you intend to continue living in an owned house in this country - either care home fees (which I don’t object to) or IHT if the house is worth 1.5m

The mansion tax does work to reduce house prices, which is obviously their aim?

Araminta1004 · 21/09/2026 15:03

I don’t think most people do benefit unless they liquidate and move somewhere far cheaper and live off the gains and have a party with it. Most people are far too good little citizens and at best leave it to their children who need it to be able to stay where they grew up and stick around their own parents in old age to provide support. So the downsizing is often done locally to help a child onto the ladder. But how many people in advanced age realistically go let’s sell the 4 bed “mansion” in Shoreditch and all go to Thailand/Dubai/Ibiza etc wherever and splash the cash. Maybe more people should do it. You would get great health care and care in Thailand at a fraction of the cost.

Yes it’s not that beneficial. It’s a very high mortgage cost and if you want to move within London or close enough to keep jobs it’s the same again.

So how are this hapless bunch of fuckwits going to arbitrarily pick a moment in time and decide what a house is 'worth'. Anything on the border line of 1.5m clearly won't be worth that any more once saddled with the additional tax yet will still be stuck with that liability for evermore

BeardySchnauzer · 21/09/2026 15:21

The other issue with a property tax like this is that whilst some people buy property as investments, most are buying a home. DH and I have been fortunate to build up to our family home which we’ve owned for 15 years and the value hasn’t gone up that much but it’s our home. We will most likely sell once the kids are independent but we won’t move areas as this is home. So yes we will liberate some capital but once you’ve knocked off stamp duty and other costs it’s not going to be enormous

Although I’m interested in how this interacts with leasehold. If you own a leasehold flat on a 150 year lease and it’s currently worth £1.5m - well that value is only going down surely?

It's perfectly possible to partially liquidate assets.

Equity release, remortgaging or lifetime mortgages are all possible.

Government has also proposed schemes where the extra tax can be deferred and accumulate as a charge on a property before it is sold.

So there are multiple solutions for the (very) small percentage of people who wouldn't otherwise be able to pay the tax due to lack of liquidity but want to remain living in the house.

and costly - taking on debt to pay the tax is not wise

Indeed. It won’t just be a one-off valuation exercise: for many properties it will be an endless series of expensive legal cases so highly likely to cost more to administer than it raises. Idiotic.

For the majority of working-age people especially those under 45 or so it has not been a source of wealth, rather a very large cost which significantly decreases their standard of living. Some are now going to have that disadvantage compounded by tax on their mortgage debt.

It was done in the past with council tax, the bands are way out of date and have been for decades. They will do anything other than cut the welfare bill, my hope is that the bond market calls time on them, but then of course the "million pound mansions" will be worth even less. Best bet for people who like their high house price mortgage free with minimal costs for services would be to vote for the bloke with five houses?

You want the poll tax 2 that nearly brought down a conservative government? They had to repeal it.

No one with any political memory would propose this. It would mean an 80 year old in a two million pound house would pay the same as a 20 year old in a small bedroom in an hmo. The unfairness brought it down first time around. And it means the young tend to pay more for less, than older people do.

why not abolish council tax completely and increase income tax if you want higher incomes to pay more? Realistically if you have a high value house you have a high income so why bother with this costly and messy solution when there is an easy one available.

council tax is merely local people paying for local services. It should be on a person by person basis. Your house value shouldn’t come into it.

This isn"t true, plenty of people renting have a higher income than an older person in a large house, hence the fuss about this proposed tax.

I agree to an extent about that group of older people but lots of people have said on this group that those people who have huge mortgages on these high value houses must have a high income to satisfy the mortgage and therefore should be able pay the extra council tax. If that is the case why not just abolish council tax and put income tax up? Save all the admin burden.

Many people took out massive mortgages when rates were nearly zero, they can"t afford the mortgage now let alone the council tax.

What utter nonsense.

The government can choose to take measures to stimulate the economy. They don’t, they have done the opposite.

The government have chosen to mothball the North Sea industries.

They are chasing away people who create wealth and employment.

They can get their hands on money other than yours or mine. They choose not to.

It’s not nonsense. Ignoring what they are doing is nonsense. If my auntie had bollocks she’d be my uncle is nonsense.

Maybe the budget will prove us wrong, but I doubt very much Labour’s are going to do anything radical to boost the economy.

Tax, spend and borrow is the only show in town.
