Owners of holiday lets in England face a fresh wave of uncertainty as the Treasury reviews the tax treatment of short-term rentals, with a potential reclassification that could strip away valuable business rates relief. The review, confirmed in a written parliamentary answer on September 10, comes ahead of the October 28 Budget, and a recent report suggests Chancellor John Healey is considering whether some properties currently treated as businesses should instead be classified as second homes.
The distinction is financially significant. A qualifying self-catering property can enter the business rates system and may receive full Small Business Rate Relief, potentially reducing the tax bill to zero. In contrast, a second home typically falls under council tax, where local authorities can charge up to double the standard bill. For owners, lenders, and accommodation platforms, the critical question is not whether a new tax rate has been set, but whether the eligibility line for business treatment is about to move.
What the Treasury has actually confirmed
In the parliamentary answer, Treasury minister James Murray confirmed that the government is reviewing the tax treatment of short-term lets, including self-catering accommodation. He acknowledged concerns that some second-home owners are using Small Business Rate Relief primarily to reduce their tax bills, while also recognizing that many self-catering properties are genuine small businesses. The review's outcome remains undecided, with a response to the earlier call for evidence promised in due course.
The Independent reported on September 18 that Healey is weighing a second-home classification for holiday lets, but no threshold, start date, or draft rule has been announced. This leaves the industry in a state of limbo, with the existing rules still in effect.
Current rules versus reported risk
Under current guidance, a property offered for short stays of no more than 28 nights qualifies for business rates only if it is available for at least 140 nights and actually let for at least 70 nights in the prior 12 months, with an intention to offer 140 nights in the next year. Owners must confirm eligibility annually, and a property that fails the test moves to council tax.
Small Business Rate Relief is substantial for smaller properties: with one property, relief reduces the bill to zero if the rateable value is £12,000 or below, tapering to £15,000. By contrast, councils can impose a premium of up to 100% on second-home council tax bills, subject to exceptions.
Alistair Handyside, chairman of the Professional Association of Self-Caterers, estimated that the reported change could cost an average owner between £1,000 and £3,000 a year. This is an industry estimate, not a Treasury costing, and the actual impact would vary based on rateable value, council tax band, location, and the premium chosen by the local council.
Separate from furnished holiday lettings repeal
This review is distinct from the recent repeal of the furnished holiday lettings income-tax regime, which ended on April 6, 2025. That repeal removed advantages such as special capital-allowance treatment and more favorable finance-cost rules, but HMRC explicitly stated that it did not change the separate council tax and business rates tests.
The new review could affect that remaining property-tax distinction. Reclassification would raise fixed costs for affected operators regardless of bookings, potentially pressuring marginal cottages and reducing accommodation supply in rural and coastal areas where hotels are scarce. The counterargument is that a tax relief intended for trading businesses can be exploited by owners who arrange limited letting activity around a second home primarily to secure a lower bill. The Treasury's challenge is to separate these cases without penalizing genuine accommodation businesses that meet real occupancy demand.
The next hard checkpoint is the Budget on October 28, formally set by HM Treasury. Investors and property owners should watch for the precise eligibility test, any transition period, and whether councils retain discretion. Until those details appear, the report remains a policy signal rather than a payable tax bill.
