The Budget and Your Property: Navigating New Taxes and Market Certainty

Yesterday’s Autumn Budget, delivered by Chancellor Rachel Reeves, brought an end to months of speculation, particularly around property taxes. While the overall market can breathe a collective sigh of relief that a broad-based tax on homes above £500,000 has been avoided, the focus has shifted to the high-value market and the private rented sector.

As your trusted property partner, we've broken down the key announcements and what they mean for homeowners, buyers, and landlords across the UK.

1. The ‘High Value Council Tax Surcharge’ (The so-called ‘Mansion Tax’)

This was arguably the biggest property announcement, but its impact is highly targeted.

What is it?

Officially named the High Value Council Tax Surcharge, this is an annual charge that will apply to properties in England valued at over £2 million (based on a 2026 valuation). It will be paid on top of existing Council Tax.

The Details:

• Timeline: The tax will come into force from April 2028.
• Cost: The surcharge will range from £2,500 per year for homes valued between £2 million and £2.5 million, up to £7,500 per year for those valued over £5 million.
• Who Pays: The charge is payable by the owner of the property, not the occupier.

Our Commentary

This new tax will directly affect a very small percentage of the total housing market (estimated at around 0.5% of homes), primarily concentrated in London and the Southeast.

Richard Cleaver, Head of Residential at Shouler & Son, comments:

“The primary takeaway here is that the vast majority of the UK housing market remains unaffected by this tax. However, even a highly targeted measure at the top end can create a ripple effect. We may see some 'bunching' of sales just below the £2 million and subsequent price bands as the 2028 implementation date draws closer.

For our clients who own these high-value properties, this introduces a new annual cost that needs to be factored into long-term ownership. It gives them ample time to plan, but it certainly doesn't help the overall sentiment at the premium end of the market.”

2. Increased Income Tax for Landlords

The private rented sector received another tax hit, following on from previous measures like the reduction in mortgage interest relief.

What is it?

From April 2027, the rates of income tax applied to rental, dividend, and savings income will increase by 2 percentage points.

The Details:

• New Tax Rates for Landlords: The basic, higher, and additional rates of income tax on property income will rise to 22%, 42%, and 47% respectively.

Our Commentary

This change will reduce the net returns for unincorporated landlords, who make up the bulk of the private rented sector. While the widely rumoured extension of National Insurance to rental income was avoided, this move places further financial pressure on investors.

Richard Cleaver advises:

“Landlords are already navigating higher borrowing costs and increased regulatory pressure, and this additional tax is another unwelcome burden. The risk is that these extra costs are ultimately passed on to tenants in the form of higher rents, further straining affordability in an already challenging rental market.

We strongly advise our landlord clients to review their portfolios and business structure with their accountant to ensure they are operating as tax-efficiently as possible. For those looking to invest, the maths has just got a little harder, but the fundamental demand for quality rental property remains very high.”

3. No Change to Stamp Duty Land Tax (SDLT)

Despite intense speculation and calls for reform, the Chancellor made no changes to the existing Stamp Duty Land Tax structure.

Our Commentary

The lack of change removes a significant layer of uncertainty that has been hanging over the market, which can now proceed with more clarity.

Richard Cleaver concludes:

“The property market hates uncertainty, and the removal of the threat of a large-scale annual property tax or sudden SDLT reform is, in itself, a positive step for market sentiment. Buyers and sellers can now proceed with greater confidence, particularly in the mid-market where activity had perhaps been held back by fear of a major change.

Overall, the Budget was not the seismic event some feared. It was highly targeted at two specific areas. For the average homeowner, mover, or first-time buyer, the biggest influences on the market remain mortgage rates, inflation, and the supply of housing. We remain committed to helping all our clients navigate this landscape with expertise and reassurance.”
