Jason Harris, Managing Director of professional property purchasing specialists, Open Property Group offers his thoughts ahead of the forthcoming Autumn Budget.
As the Autumn Budget is officially scheduled for 26 November 2025, landlords across the UK are watching with mounting concern.
The Stakes at Play
With the UK facing a daunting fiscal shortfall—estimates range from £20 billion to £50 billion—the government is searching widely for additional revenue streams. Against a pledge not to increase VAT, income tax, or employee National Insurance, attention has increasingly turned to property as a source of funds.
The Speculated Tax Measures
Several policy ideas are circulating in preparation for the Budget:
- National Insurance on Rental Income
Landlords might see their rental income treated similarly to wages, subject to an 8% NIC levy—a change that could raise around £2 billion, effectively broadening the NI base.
- Stamp Duty Replaced with Annual Property Tax
Instead of an upfront charge, homeowners (including landlords) may pay a recurring, value-based levy. Models suggest rates around 0.5% annually for property values above thresholds such as £500,000 or even £1.5 million.
- CGT Exemption Removed for High-Value Homes
The relief from Capital Gains Tax on a primary residence may be lifted for homes valued over £1.5 million, capturing a revenue stream from otherwise excluded capital gains.
- Other Property-Tax Measures
Additional possibilities include a mansion tax, reforms to council tax, and tweaks to stamp duty thresholds, all designed to collect more from property owners.
Why Landlords Should Be Worried
- Rising Costs & Lowered Returns
An 8% NIC on rental income dramatically cuts net profitability. Landlords in moderate-return portfolios- especially those renting lower-priced units, might see profits wiped out or be forced to raise rents to keep afloat.
- Market Distortion and Reduced Supply
New landlord taxes could trigger exits from the rental market, reducing housing supply, delaying property turnover, and increasing rents for tenants.
- Transaction Freeze
Speculation alone is already causing market paralysis, high-value homeowners and landlords are hesitating to put homes on the market, waiting for policy clarity.
- Regressive Impacts
These reforms could hit asset-rich but cash-poor owners, pensioners or long-time landlords, who may struggle with annual levies despite limited disposable income.
A Call for Thoughtful, Balanced Reform
The Autumn Budget arrives amid fiscal urgency. But policymakers must tread carefully—not all revenue has to come through punitive or destabilizing measures on property. For landlords, understanding the potential impact is crucial, not just on profitability, but on housing supply, tenant costs, and the broader market equilibrium.
A measured approach, possibly involving phased changes, exemptions for small-scale landlords, or alternative revenue models, will preserve both tax fairness and a healthy rental ecosystem. As we await the Chancellor’s announcements, stakeholders should prepare, but resist reactive decisions driven by speculation.
