Possible Property Tax Shake-Up: Stamp Duty Could Be on the Way Out

In what could mark the biggest property tax shake-up in British history, Chancellor Rachel Reeves is exploring plans to scrap stamp duty on most home sales and bring in a new tax targeting more expensive properties.

According to a report published in The Guardian, the Treasury is actively weighing up a national property tax that would apply when homes worth over £500,000 are sold.

The aim? To replace stamp duty, widely seen as outdated and unfair, with something simpler, more consistent, and ultimately, fairer.

It’s all part of a broader effort to tap into the massive wealth stored in Britain’s housing market, while steering clear of breaking the government’s promise not to raise taxes on working people.

Is Stamp Duty on the Way Out?

Stamp duty has long been a sore spot for buyers. It can force individuals, who have probably spent their life savings on buying a house, to pay tens of thousands more in taxes. And with rates varying depending on whether you're a first-time buyer or not, the system has become a patchwork of confusing thresholds.

Last year, stamp duty brought in around £11.6 billion, but revenues swing wildly depending on the state of the housing market. That volatility has made it tough for the government to plan its budgets.

Enter the new idea: a proportional national property tax. Instead of taxing buyers at the time of purchase, this tax would be paid by the seller, but only if the property sells for more than £500,000. That’s roughly double the UK’s current average home price of £272,664, meaning most households wouldn’t be affected.

The proposal, still under review, is expected to hit only about 20% of property transactions, those involving high-value properties. This is a much narrower group than the roughly 60% currently facing stamp duty.

Crucially, the new tax would not replace stamp duty on second homes or investment properties, at least not right away.

Is This Property Tax Shake-Up Necessary?

There’s pressure coming at Chancellor Reeves from all directions. On the one hand, the government needs money urgently. Britain’s public finances are still under serious strain, and those at the top know they can’t just borrow their way out.

But on the other hand, Chancellor Reeves and Prime Minister Keir Starmer are determined to stick to their tax promises. They’ve ruled out hiking Income Tax, VAT or National Insurance. So, they’re looking elsewhere — and wealth, particularly in property, is a prime target.

Deputy Prime Minister Angela Rayner and other senior Labour voices have also been pushing for more “wealth-based” taxes to help tackle inequality and fund struggling public services.

It’s not just about plugging holes in the budget. Economically and politically, there’s an appetite to fix what many economists call one of the most broken parts of the tax system.

Council Tax is Also Under the Microscope

While stamp duty might get replaced sooner, a bigger and arguably trickier reform looms in the background – Council Tax.

Officials are examining whether, after the national property tax is in place, a new local version could replace Council Tax altogether. That plan, inspired in part by ideas from the centre-right thinktank Onward, would charge property owners an annual fee based on their home’s current market value.

In practice, this could mean a flat annual tax starting at around £800 for homes under £500,000, with higher-value homes paying more. The revenue would go directly to local councils, many of which are in serious financial distress.

Local authority finances have been on the brink for years. Some councils are already facing effective bankruptcy, and Labour (now running many of them) doesn’t want that crisis deepening on its watch.

What is the Government’s Goal With This Property Tax Shake-Up?

No final decisions have been made. The Treasury is still modelling how these new taxes could work, and sources say the national property tax could be rolled out during this parliament.

Reforming Council Tax, however, would likely take much longer and would almost certainly require Labour to win a second term in office.

The changes are part of a broader rethinking of how wealth is taxed in the UK. Last week, The Guardian also reported that the Treasury is looking into reforms to Inheritance Tax, another deeply unpopular and complex levy. There are even whispers about how VAT could be tweaked for private schools and farms, which are areas where ministers may be less afraid of upsetting wealthier households.

A Tax That Moves with the Market

One of the key arguments in favour of the new national property tax is that it would be more stable. Stamp duty revenue jumps around depending on how hot the housing market is. In contrast, a seller’s tax based on a fixed rate and only applied to higher-value properties is expected to be more reliable.

And it could also encourage mobility. Stamp duty has been criticised for discouraging people from moving, especially downsizers who might otherwise sell up and free up larger homes for growing families. Removing that barrier could help the housing market flow more smoothly.

As an economist put it, the proposal to get rid of Stamp Duty would make it easier and cheaper to move house, for a better job, or to be near family. It would also be fairer.

Isn’t This a Political Gamble?

It is. Any talk of new taxes is. Even if they only hit the wealthier end of the market, property taxes tend to stir up strong emotions. Some critics will inevitably frame the move as a “homeowner penalty.”

But the government is banking on two things. First, most people won’t be affected. And second, frustration with stamp duty and Council Tax is so widespread that replacing them could actually prove popular.

If the messaging is right, and if the new system feels more transparent and reasonable, the government might just be able to bring the public along.

Conclusion

With Reeves’s Autumn Budget 2025 on the horizon, expect to hear more soon. Whether these plans make it into the final statement or remain in the pipeline for future reform, one thing is clear: Britain’s property tax system is finally getting a serious look.

And for the millions of homeowners, renters, buyers, and local councils affected, that could mean big changes ahead.
