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.

There is only one principle of taxation:

Extract as much as possible under threat of force without people noticing, refusing to pay, and ultimately rebelling.

We've had taxes on property, windows (a proxy for the value of your house), and beards.

Interesting though that commercial buildings, or residential buildings owned by a company, are not subjected to the tax, nor people that rent a high value property.

I'm therefore waiting for some mortgage company to come up with some elaborate hire purchase scheme to replace a standard mortgage.

.

I suspect it won't be long.

People hate inheritance tax though (even though most won't pay it) which is when you could tax on house profits. Trouble is of course is that it's fairly easy to avoid with inheritance planning so it becomes a tax on putting all your eggs in one basket. Nobody rich is really affected by it.

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

It’s not about how many it hits, it’s what it does to behaviour. £2m+ owners who can, sit tight. Those those near the line suddenly discover “fixtures and fittings”, and £3 -£5m buyers might just absorb. We haven’t even seen the damage from the council tax revaluations yet.

Meanwhile this false-flag tax still ignores the real drivers of inequality and just hands discounted stock to the cash buyers waiting to hoover it up.

I’m sorry but my violin is really really tiny on this issue. As it was for the couple on £120k complaining about the tax relief changes on ISAs on the bbc website.

maltravers · 30/11/2025 22:58

My objection to it is the north/south divide. So someone in an expensive London house pays, while someone with a bigger house in the north where prices are lower pays nothing - that doesn’t seem fair to me. It seems like a tax on the SE.

I am not affected by this policy but but I recognise what it does and where it is heading. I accept that I will have to pay more tax because I accept that comes with living in civilised society. What I don’t accept is being told to swallow bad policy that pretends to tackle inequality while actually entrenching it. If you’re going to ask people to pay more, the least you can do is target the causes of inequality, not load more pressure onto the consequences of a broken system.

It takes a special kind of person to be so wrapped up in jealousy and ignorance that they can’t even recognise the government screwing other people over. Mocking savers for being upset when the goalposts on ISAs get moved isn’t insight, it just advertises how little you know. If I was you I would give up the violin routine, you wouldn’t recognise a good tune even if it hit you in the face.

So the real issue is that people in the North might miss out on being hit by a bad tax? Don't worry the council tax brands will stick it to them...

Why aren't you focused on why the government can get away with imposing a bad tax? The North isn’t the problem here. You are fighting the wrong enemy.

There are no principles of taxation and this is an issue (like private schools VAT) where most people won’t play their sympathy violins fornyou

I think you miss off a doo...

I’m not affected by the mansion tax. If you put down the violins and paused the knuckle-dragging for just a second, you might finally hear the point whistling past.

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.

Sadly, I suspect they were not the only ones. And so it begins...

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

They learned their lesson from the Poll Tax which is why they started small this time. Who is going to kick up a fuss for the 'wealthy'...

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.

This will happen. Look at where student loans started...

I’m not jealous or ignorant. I mean you have no idea of my financial circumstances to know if I need to be jealous do you? But I will save my sympathy for people struggling to feed their kids rather than people moaning that their preferred method of saving is now less tax efficient.

I’m someone that spends probably too much of their lives looking at tax policy. This is a terrible policy. Anyone with a house that is deemed just over £2m will fight the valuation tooth and nail. Our tax courts will be stuffed to the rafters with valuation disputes a. The fact that HMRC deems a property to be over £2m automatically devalues it by a couple of hundred thousand. I don’t think many will try to avoid it. You don’t see much stamp duty avoidance to do with messing with the valuation as doing so is very dodgy and could invalidate your ownership of your property.

But yes, a bad tax due to lazy implementation.

'Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime'.

People struggling don’t need endless handouts to trap them there, they need short-term support and real routes into skills, work and productivity - similar to the Nordic states provision from what I understand of it. Saving drives growth, growth drives wages, and wages pay for benefits and the support that feeds kids. Attack saving and work and you don’t help the poor or starving children you just make the river have fewer fish to feed an ever increasing number of mouths.

A working couple on £120k, being productive and doing the right things, aren’t the ones to sneer at. I save my contempt for the people who hand out sympathy and cheques just to keep people stuck where they are. That’s not support it's a noose.

It’s a veritable can of worms: bank valuation for the mortgage, government valuation for tax, actual sale price in the market. Potentially three prices for one house. What could possibly go wrong?

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

Absolute nonsense.

But it also means that the people who bought houses years ago, lived in them for years, now have to find income to stay in them or sell and move (far) away.

But those get no sympathy from the baying packs of wolves appearing on MN because obviously if a person or pensioner lives in a £2m house, even if they didnt buy a £2m house then they should sell it... (because only the real rich should have £2m houses, not the fake ones)

I fit into neither category
