Autumn Budget 2026: The Key Changes Affecting Buy-to-Let Landlords

Main Autumn Budget 2026 talking points for landlords

The Budget was delivered on 28 October 2026. The Government has confirmed a further two-percentage-point increase, which will take the basic rate to 24%, the higher rate to 44% and the additional rate to 49% from April 2027.

Beyond that headline tax rise, these are the developments;

1. Changes to Self Assessment tax payments

The Government has announced plans to reform how Self Assessment tax is paid from 2029, moving towards smaller, more frequent payments rather than relying on the existing January payment cycle.

Why it matters: Landlords will need to manage cash flow more carefully, particularly where rental profits are already being squeezed by mortgage costs, repairs and taxation. The exact payment arrangements have yet to be confirmed.

2. Making Tax Digital will affect more landlords

This was announced previously, rather than being a new Budget measure, but remains significant.

• April 2026: qualifying income over £50,000.
• April 2027: threshold reduces to £30,000.
• Landlords within scope must maintain digital records and submit quarterly updates.

For landlords with several properties, this adds to the administrative requirements of operating a rental business.

3. High-value property surcharge from April 2028

The Government confirmed further details of the High Value Council Tax Surcharge affecting residential properties in England valued at £2 million or more.

The surcharge falls on the property owner, not the tenant, making it relevant to landlords with high-value rental houses in prime London locations.

4. No significant Stamp Duty relief for buy-to-let investors

The Budget did not introduce a major reduction in Stamp Duty Land Tax to encourage private buy-to-let investment. Higher acquisition costs therefore remain a barrier for landlords considering expanding their portfolios. There is, however, a technical change to remove SDLT on the rent element of assured tenancies, previously announced in April 2026.

5. Government support for first-time buyers

The new Your First Home scheme will provide government-backed equity loans of 20%, with a five-year interest-free period and a minimum buyer deposit of 2.5%. The scheme is intended to launch in spring 2027, with £4.7 billion allocated. This is principally a homeownership initiative rather than support for the PRS. It may help some tenants purchase homes, but does not directly address the financial incentives for private landlords to provide rental accommodation.

6. Frozen income tax thresholds continue to squeeze landlords

Income tax thresholds remain frozen, creating fiscal drag. This means landlords whose taxable income increases over time can move into higher tax bands without enjoying a corresponding real-terms improvement in their finances. Combined with the new property income tax rates, this could further reduce net rental returns.

7. No reversal of Section 24 mortgage interest restrictions

The Budget did not reverse the existing restrictions on mortgage finance cost relief for individual residential landlords. This is particularly important because the new 44% higher property income tax rate will operate alongside the restrictions on deducting mortgage interest. A landlord with substantial mortgage borrowing may therefore face a tax liability that is disproportionately high compared with the cash actually retained from the property. Industry representatives have warned that the combination could encourage landlords to sell rather than continue investing.

8. Additional affordable housing investment — but not direct PRS support

The Budget allocated a further £1.5 billion to the Social and Affordable Homes Programme, intended to support approximately 10,000 additional homes in England. This is welcome investment in housing supply, but it does not provide equivalent financial support for individual private landlords.
