That's only one aspect of what they are proposing though.
They are also looking at:
Proposed Seller-Paid Property Tax -
"The government is considering a radical shift in property taxation: scrapping the current Stamp Duty Land Tax (SDLT)—paid by buyers—and replacing it with a seller-paid tax on higher-value property sales. Key details under discussion include:
Threshold: Applies only to properties sold for over £500,000.
Who pays: The seller, not the buyer.
Proposed rates:
0.54% of the sale price for homes between £500,000 and £1 million
An additional 0.278% surcharge on the portion above £1 million
That means:
Selling a £600,000 property could cost ~£3,240
Selling a £1.2 million property could cost ~£8,500
Context: This shift aims to reduce the upfront burden on buyers (especially first-time buyers) and improve housing market fluidity—though critics warn it could still further hinder downsizing and disproportionately affect high-value markets".
Other Tax Proposals of Note
Capital Gains Tax (CGT) on Primary Homes: The exemption for main residences might be removed for properties sold over £1.5 million, meaning sellers could owe CGT—18% for basic rate taxpayers, 24% for higher rate—on any gain.
What You are referring to @DrPrunesqualer is:
Annual Property Tax: In the longer term, the government may introduce an annual property tax to replace both stamp duty and council tax. This could be based on property values.
All proposals at this stage, but there's a lot more on the table that could be announced in the Autumn budget.
