Budget uncertainty and property tax rumours: Should you wait or act now?
Property tax speculation has been one more reason for some buyers and sellers to hesitate this summer. But as we move further into August, it is important to separate rumours from policies that have actually been announced.
The market itself is subdued. The latest RICS Residential Market Survey showed new buyer enquiries at a net balance of minus 28% in July and agreed sales at minus 30%, meaning more survey respondents continued to report falls than rises. RICS said geopolitics, the domestic political climate, and mortgage costs were continuing to weigh on sentiment. The July survey is here: https://www.rics.org/news-insights/uk-residential-survey-july-2026
But some of the uncertainty around property taxation has reduced since those concerns first emerged. That changes the question from “what taxes might suddenly change?” to the more practical one of whether waiting still improves your position.
What has actually been ruled out?
One of the biggest rumours concerned Stamp Duty Land Tax. Prime Minister Andy Burnham explicitly ruled out changing or scrapping stamp duty at the next Budget on 27 July. Reuters reported that, when asked directly whether the government would make changes, he said that would not be happening. The Reuters report is here: https://www.reuters.com/world/uk/uk-pm-burnham-rules-out-changes-stamp-duty-next-budget-2026-07-27/
That means someone purchasing a property should not currently base a decision to delay solely on the hope that stamp duty will be removed or substantially changed in the coming Budget.
There continues to be wider political debate about whether Britain’s property taxes should eventually be reformed. Council tax in particular remains controversial because homes in England are still assigned to bands based on historic valuations. But discussion about longer term reform is very different from confirmed Budget policy.
One property tax change is already confirmed
There is, however, an important distinction for owners and buyers of high value homes. The High Value Council Tax Surcharge was announced in the 2025 Budget and is due to take effect from April 2028 for residential properties in England valued at £2 million or more.
The proposed annual charges start at £2,500 for properties worth between £2 million and £2.5 million, rising to £7,500 for properties worth more than £5 million. This is an additional charge rather than a replacement for existing council tax. The House of Commons Library summary is here: https://commonslibrary.parliament.uk/research-briefings/cbp-10869/
That should therefore be treated as a genuine planning consideration for relevant high value buyers rather than grouped together with general Budget rumours.
Has uncertainty already affected the market?
The latest August evidence suggests confidence may respond quite quickly when uncertainty reduces. Rightmove reported that buyer demand rose by 5% after Andy Burnham became Prime Minister on 20 July, and said his announcement that property taxes would not be changed in the October Budget should give buyers more certainty heading into autumn.
At the same time, conditions still favour careful buyers. Rightmove said the average asking price of a newly listed property fell by 2% in August to £364,999, which was a larger August drop than usual. It also reported that the number of homes available for sale was at its highest level for this time of year since 2014. The latest Rightmove House Price Index is here: https://www.rightmove.co.uk/news/house-price-index/
These are asking prices rather than completed sale prices, so they should not be treated as proof that every property is becoming cheaper. But they do suggest buyers currently have considerable choice and that sellers are having to think carefully about pricing.
Should buyers wait for the Budget?
There is no single answer, because the right timing depends on why you are moving.
If you have not found a property you want, there is little reason to manufacture urgency around the Budget. Keep looking, understand your borrowing capacity, and be ready when something appropriate appears.
If you have already found the right property and the numbers work, delaying purely because of tax rumours may be harder to justify now that stamp duty changes at the next Budget have been ruled out. Waiting also introduces other uncertainties, including mortgage rates, seller decisions, and whether the property remains available.
A quieter market can sometimes create opportunities. Where sellers have been waiting longer or are competing with more listings, a well prepared buyer may have greater scope to negotiate.
What sellers should consider
For sellers, uncertainty makes realistic pricing particularly important. RICS continues to describe demand and sales as subdued, while Rightmove says buyers currently have plenty of choice. An ambitious asking price may therefore cause a property to sit on the market while buyers focus elsewhere.
That does not mean sellers should automatically accept a large discount. It means local evidence matters. Recent comparable sales, competing listings, and how quickly similar properties are attracting offers are more useful than trying to price around hypothetical Budget announcements.
Practical takeaways
Do not make a major property decision based only on a tax rumour. Distinguish confirmed measures from political discussion, calculate the costs that actually apply to you today, and consider what waiting could change in both directions.
For some buyers, current uncertainty may actually strengthen their negotiating position. For others, particularly those considering homes above £2 million, confirmed future tax measures deserve closer attention.
