To think that the mansion tax breaks the principles of taxation

Most taxes fall into:
Income you receive
Profit you realise
Spending you choose

Council tax sit outisde of this. Its more like levy based valuation bandings and was a quick and dirty fix after the poll tax fiasco. It is effectively a service charge not a wealth tax.

Whereas mansion tax is the government estimating the value your actual house, then treating this valuation as pure profit then taxing you on this. Given the majority of homes are purchased with mortgages and paid for by already taxed money:

Why is

Mansion Tax = Estmated value × %

More reasonable than

CGT = Profit * % (Profit = Actual sales price - (Purchase price + actutal costs)

With actual costs being renovations not stamp duty or interest paid on your mortgage

I am not in the mansion tax bracket. I do accept that some taxes need to rise but I don't believe this is the solution.

is taxing ownership of an asset new?

Well see how far you get without taxing your car, and get back to me.

But taxing your car is linked to emissions and you don't have to pay if you aren't driving it (SORN). It's a tax on using your car on the public roads. Not the same at all.

It's absolute nonsense.

But it will work like arsenic. Low dose at first, barely noticed (piddling), then quietly lethal once it’s sunk into the system.

Nah. It’ll be abolished when Labour are ousted at the next election.

@ByQuaintAzureWasp. We tried that, didn’t go down well! Don’t you remember the poll tax riots

Wealth taxes are part of most countries tax mix. You need a mix to ensure the savvy with expensive accountants don’t pay less than ordinary people on paye (pure income taxes can be quite unfair because those with the most means to pay often pay less). If you can afford a £2m house then these relatively small amounts are pocket money. I pay nearly £3k for my band e house, my share is 10% of my income!

I don't think it was thought out. Expensive houses aren't selling already because of stamp duty threshold it almost becomes a double tax on wealth, and it will trap some people in homes they can't sell. I'm not anywhere close to the threshold for mansions tax but you do wonder if it will be one of those taxes where the thresholds don't change and in 20 years every home owner will have to pay it.

I definitely think this will happen. Actually I expect that once it's been embedded for a few years the thresholds could well gradually reduce. It's a tax that won't raise a great deal at the moment but will be much more worthwhile for the government the more people are brought into it's scope.

Also - please correct me if I'm wrong but is taxing ownership of an asset new? Most taxes are either service charges (eg council tax, vehicle excise duty), target transactions (income tax, CGT) or levied at the time assets are realised (IHT). Can anyone think of any other taxes that exist to tax ownership of something? It seems that once this principle is established it's a small step to extend this to taxing other assets just for owning them.

ByQuaintAzureWasp · 30/11/2025 09:48

Its bloody ridiculous (im nowhere near or ever will have a £2m house).
Its for local services and should be per adult head count.

I wonder how many property sales will go through at £1.99M with the extra booked as fixtures and fittings to avoid the levy ...

On top of this, there will non be a group of people who decide it is now financial suicide to move up the ladder

you're talking about a tiny number of property owners, and you're not taking account of those who already live in £2m+ houses who aren't going to move because they now have to pay £2,500 a year extra.

neither will people stop their house move plans because of the tax, they'll have predicted this and now be working with their vendor to avoid the levy by the method I've mentioned at the top of my post. Anyone buying a £3-5m house isn't going to be bothered either.

Edited

ISTR there was a mumsnetter on another thread (I didn't 'watch' it so can't link) who said their property transaction collapsed the day after the budget due to this tax.

That will only work within a particular band of value though and will be pretty counter productive

It will work at all bands because the amount they are charged is going to be a percentage of the price the property is valued at.

My friend lived in Durban. Property taxes were 0.9% of the value of the property each year. So if you had a £2m house you've be paying £15k per month. When you look at through that lens, £200 per month which can be deferred til you sell or die seems quite reasonable.

I think the tax is OK: the baby boomer generation who I think are by far the biggest owners in this bracket didn't pay enough tax through their lifetime and are now creating big NHS expenses. So the wealthiest of them - and the millionaires who put their wealth away from the reaches of our state while enjoying all the benefits of it - can fund it out of their unearned wealth.

I think it also has the added benefit of curbing house price rises and starting gently deflating the housing market, which is needed so our young people can start to buy houses of their own but not so much that it causes a crash. It also encourages people to live in the right-sized houses.

Had a look at Durban…

Durban is what you get when wealth tax policy is built on the back of a fag packet, a heavy dose of liberal bias, and a lot of dog-whistling about 'fairness' and 'mobility'. It’s the real world version of what that 'tax wealth harder and hope for the best' actually looks like when growth and capital mobility are ignored.

It will also be like the window tax, which caused people to brick up window in their homes in the 18th century. People will let properties fall into a state of neglect to prevent them being valued too highly.

We need to start taxing wealth, not income.
income doesn’t make you wealthy. As a high earning dual high income family, with high mortgage, high childcare fees, high cost of living, but no inherited wealth, we are not wealthy.
We’ve both worked extremely hard, done several degrees with no financial backing or wealth behind us. We’ve always worked very long hours, weekends, late into the night.
It’s been a long uphill struggle and the future is still uncertain.

Those around us with familial wealth, land, multiple properties, very high value properties who themselves work much less, earn much less, spend more time with their kids, yet pay less tax. All whilst being able to afford multiple holidays and private school. How is this fair? Income tax does not tax true wealth.

We should be taxing billionaires, big corporations, those with land/multiple properties and prevent wealth from being off-shored. The real reason times are getting harder is that true wealth, large assets, land, global corporations are not taxed enough.

I agree with this. You can work till you are killing yourself with stress in a high paid job and you still won't have a fraction of the wealth of Jenny down the street who is currently renting a property from her dad, having UC pay the rent and working PT and will then inherit her dad's (paid for by UC) property empire in due course (and I personally know quite a number of mums doing this!)

Legally, they can tax what but as we saw with the poll tax it can lead to distortion, backlash and policy failure. It doesn't mean that it is a reasonable or well designed tax.

The IFS has done a great series on tax if you’re interested. Arguing it’s a bad tax is different to making stuff up about principals of taxation that don’t exist. If enough people don’t like it then they will be voted out at the next election.

What @Mslak said

I didn’t say anything about tax being old. I said governments can tax anything they like and if we don’t like it we can vote them out.

Savoury · 30/11/2025 09:20

Responding to the poster who said this will raise half a million for flood defences. The truth is that half a billion is very little, way more than the welfare reform that Labour Reform MPs wouldn’t stomach and much less than all other tax raising mechanisms. It could cost more to administer at the start so they’re only doing it to expand to many more homes soon.
It is like the farmer inheritance changes and VAT on school fees - a starter before the main course.

Tbh, the mansion ‘tax’ is so piddling in value, it’s really just a political statement - ‘Look! We’re taxing the rich!’

Absolute nonsense.

If it has a mortgage surely the bank owns that bit so they should chip in

TangoWhiskeyAlphaTango1 · 29/11/2025 12:17

I disagree with it. Older people who bought their London homes 60 years ago in places like Hackney maybe sitting on a gold mine and are most likely asset rich but cash poor. Are they expected to sell up in order to pay this tax.

I honestly don't think it will go ahead. Forget the demonisation of the working class, now its the demonisation of anyone who earns well. I am not a big earner either but sick of hearing about rich people.

Maybe we can let them secure it as a charge against their property instead. Then the money can be collected when the property is sold.

They didnt earn all that value. It came from a crazy escalation in house prices that is causing others to struggle to even dream of buying a home

I would have preferred more council tax bands and only having the single person's discount for lower bands.

Me too. Much fairer. Although I'm in favour of the mansion tax (because rich people can hide all their other wealth), another cliff edge is going to have lots of attached problems.

The rich get richer, and everyone else gets forced out.

how are "the rich getting richer" in this scenario?

Capital Gains Tax at least works off actual profit, not a morally dodgy valuation that treats the whole house as if it were pure gain. Paired with the removal/ significant reduction of samp duty for downsizers it could free. Help free up the market.

There is already stacking. You pay tax on the income you earned to buy the house, then Stamp Duty Land Tax at purchase, then Council Tax every year, and now a mansion tax on top. The same home is taxed four times. It’s sold as 'fairness' and encouraging downsizing, but it won’t stop at £2m. It never does. SDLT is at least a one-off. The others are permanent and will only rise. The mansion tax is more likely to exists because Rachel Reeves has run out of room to push income tax higher and she needs more money to waste.

It still won’t free up homes for ordinary families. They are still blocked by deposits, mortgage rates and affordability. On top of this, there will non be a group of people who decide it is now financial suicide to move up the ladder. And just like that another group of people who can't or wont move but this group will be blocking the housing market for families.

The forced sales are likely be snaffled up by the holdersof liquid capital. They love a good distress sale! They’ll clean using tax / wealth planning loopholes, whilst enjoying gains in wealth from wholesale redevelopments, flat conversions and HMOs.
