It taxes the land, not the house
This is the whole idea, and nearly every scary number you will see ignores it. A land value tax is charged on the value of the plot, not the value of the building standing on it.
The way it is modelled, land value is what is left when you take the property's value and subtract what it would cost to rebuild the house today. A £400,000 house that would cost £180,000 to rebuild is sitting on roughly £220,000 of land. Across the UK, land works out at about 55% of housing value, so as a rough rule, a land value tax applies to a bit over half of what your home is worth.
Why that matters so much: take a headline rate, apply it to a full property price, and you get a number far bigger than anyone would actually pay. That is the mistake behind most of the eye-watering figures doing the rounds.
Where 1.28% comes from
Tax Policy Associates modelled what rate would be needed to replace English residential council tax and residential stamp duty without the Treasury losing money. The answer came out at 1.28% of land value a year.
Not an extra tax. A swap: no more council tax bill, and no stamp duty when you move.
1.28% is not as frightening as it sounds next to 0.48%
I have written before about a 0.48% proportional property tax, and the two rates get compared as if 1.28% is nearly three times worse. They are not measuring the same thing.
- 0.48% is charged on the whole property value.
- 1.28% is charged on the land only — about 55% of the value.
Run 1.28% against 55% and you land at roughly 0.70% of property value. Still more than 0.48%, and it should be. The land value tax is also replacing stamp duty, which the 0.48% version was not designed to do.
What it looks like on real houses
These are from the modelling, not from me:
- A £200,000 four-bedroom house in Blackpool — about £459 a year, against roughly £2,100 of council tax today. A saving of about £1,641.
- A £520,000 flat in Islington — about £5,600 a year, against roughly £2,000 today. Around £3,600 worse off.
- A £3.4m house in the same part of London — about £12,800 a year.
Look at the last two together, because they are the argument in miniature. The £3.4m house is worth more than six times the flat, and pays a bit over twice as much. Flats sit on a slice of a plot shared between everyone in the building, so the land per home is small. A land value tax is unusually kind to flats and unusually harsh on houses with gardens.
And in much of the north the bill goes down, sharply. Where property values are low enough that rebuild cost eats most of the value, the land underneath is worth very little, and the tax on it approaches nothing.
So who wins and who loses
Better off: low-value areas, flats, and anyone who moves often — no stamp duty means no five-figure bill every time you change house.
Worse off: London and the south-east, houses on generous plots, and people who bought long ago and stayed put. Council tax is still based on 1991 valuations, so a house that has quietly quadrupled in value has been paying a bill frozen in the era it was assessed. A land tax ends that.
The awkward group: asset-rich, income-poor households. Someone retired in a house that has appreciated for thirty years could face a bill several times their current council tax, out of a pension that has not moved with it. Every serious proposal wrestles with deferral schemes for exactly this, and none of them has solved it neatly.
Is any of this actually happening?
No, and it is worth being blunt about that, because there is a lot of confident writing suggesting otherwise.
A land value tax is a proposal, not policy. Reports that the government is actively planning to replace council tax and stamp duty with a single annual tax have been rejected. The Autumn Budget is on 28 October 2026 and nothing here is confirmed until the Chancellor stands up.
What did pass is narrower: a High Value Council Tax Surcharge, the mansion tax, announced in the November 2025 Budget, on homes worth over £2m. That is real, and it is a long way from replacing council tax altogether.
The reason land value tax keeps resurfacing is that council tax is genuinely indefensible in its current form. It is still calculated from 1991 valuations, and it is regressive: as a share of value, a cheap house pays far more than an expensive one. Everyone agrees it needs fixing. Nobody agrees on what replaces it, because every alternative creates a large group of visible losers.
See what a property tax would do to your bill
The proportional property tax calculator shows what a 0.48% charge on your home's value would cost against your current council tax, for England, Scotland, Wales and Northern Ireland. It models a property-value tax rather than a land value tax. The land figures above need a plot valuation nobody publishes yet, but it is the closest you can get to your own number today.

Between now and 28 October there will be a lot of noise. Two things worth applying to anything you read.
Check what the rate is charged on. If a piece quotes a land value tax rate against a full property price, the number is inflated and so is everything built on it.
Check whether stamp duty goes. An annual charge that also removes a £15,000 bill every time you move is a very different proposition from one stacked on top of it. Several write-ups quietly forget the second half.
