Furnished Holiday Lettings Abolition: HMRC Enquiries Into Historic Claims

The favourable tax treatment of furnished holiday lettings ended with Finance Act 2025. That does not close the door on HMRC scrutiny, it opens a specific new one. Every year in which FHL status was claimed before the abolition remains open to challenge if it falls within HMRC's normal enquiry or discovery assessment window, and the tests that determined whether a property genuinely qualified are exactly the kind of factual questions HMRC is well practised at picking apart.

What Finance Act 2025 actually changed

Finance Act 2025 abolished the special tax treatment of the commercial letting of furnished holiday accommodation. FHL businesses are now treated in the same way as any other property letting business. The change applies to income tax from the 2025/26 tax year, to corporation tax for accounting periods beginning on or after 1 April 2025, to capital allowances for periods of account beginning on or after 6 April 2025 (income tax) or 1 April 2025 (corporation tax), and to capital gains tax for disposals made on or after 6 April 2025 (1 April 2025 for gains subject to corporation tax).

Before abolition, FHLs benefited from treatment closer to a trade than an ordinary letting business: full mortgage interest deductibility rather than the restricted relief that applies to residential landlords, access to capital allowances on furniture and equipment, and eligibility for certain capital gains reliefs (such as rollover relief and Business Asset Disposal Relief) not otherwise available to property businesses. Those advantages are now gone for current and future years. What is not gone is HMRC's ability to look back.

The three tests that decided whether a property qualified

For any year up to and including 2024/25, an FHL claim depended on satisfying three statutory tests, and HMRC's enquiries into historic years focus squarely on whether they were genuinely met.

The availability condition required the accommodation to be available for commercial letting to the public for at least 210 days in the tax year. The letting condition required it to actually be let commercially for at least 105 of those days, not merely offered. The pattern of occupation condition capped longer-term lettings, those exceeding 31 consecutive days, at no more than 155 days in total; where a single letting ran longer than 31 days, none of those days counted towards the 105-day letting condition at all, and exceeding the 155-day cap disqualified the property for that year regardless of the other two tests.

Two elections could rescue a claim that would otherwise fail the letting condition. The averaging election let an owner with multiple qualifying FHL properties apply the 105-day letting test across the average of all of them, so a strong-performing property could carry a weaker one. The period of grace election allowed a year to be treated as qualifying where the letting condition had genuinely been met in the immediately preceding year, covering the elected year and potentially a second subsequent year. Both elections had to be made correctly and within time, an averaging election within a year of the 31 January filing deadline for the relevant tax year, and both are exactly the kind of technical step HMRC checks was actually completed properly rather than assumed.

The transitional traps for 2025/26 onward

Ceasing to qualify as an FHL would ordinarily trigger a balancing event for capital allowances purposes, potentially producing an immediate tax charge where the allowances already given exceed the property's actual depreciation. That charge is suspended for anyone who continues letting the property after 5 April 2025, but it is not written off, it is deferred, and the mechanics of exactly when and how it might still crystallise (for example, on a later disposal) are a live area where HMRC's position and a taxpayer's expectations can diverge.

The existing capital allowances pool continues to attract writing-down allowances, but any new expenditure incurred on or after the operative date no longer qualifies for the favourable FHL capital allowances treatment; the property instead qualifies for replacement of domestic items relief, in line with ordinary residential lettings. Correctly drawing the line between what counts as continuing pool expenditure and what counts as new, post-abolition expenditure is a straightforward area for HMRC to query where the accounting has not clearly separated the two. FHL losses carried forward into 2025/26 are merged into the owner's general UK or overseas property business losses, provided that business continues, another area where the mechanics of the merger are worth getting right rather than assumed.

How these cases typically unfold

Case A: The property that was advertised, not let

A couple claim FHL status on a coastal cottage for 2022/23 and 2023/24, relying on year-round listing across two booking platforms to satisfy the availability condition. HMRC opens an enquiry into 2023/24 (still within the enquiry window) and requests booking confirmations and platform payout statements rather than the listing history. The records show genuine paid bookings totalling 88 days, short of the 105-day letting condition, with the shortfall explained by a slow shoulder season the owners had not tracked separately from general availability. Because no averaging election was made (the couple owned only the one property) and no period of grace election was filed in time, the claim fails for that year. The property reverts to ordinary property business treatment for 2023/24, with mortgage interest relief restricted accordingly and the FHL-specific capital allowances claim disallowed, producing an additional liability that a period of grace election, filed correctly the following January, would have avoided entirely.

Case B: The averaging election that wasn't recorded correctly

An owner of four FHL cottages relies on an averaging election to bring a consistently under-performing fourth property up to the 105-day threshold across the portfolio. HMRC's enquiry focuses on whether the election was validly made, since no explicit election letter was found on file, only a set of accounts prepared on an averaged basis. Because the accountant can produce email correspondence contemporaneously setting out the average calculation and the intention to elect, submitted to HMRC alongside the return within the statutory time limit, the election is accepted as validly made in substance despite the informal form. A less complete paper trail would have left the fourth property's FHL status, and the capital allowances and reliefs that depended on it, exposed.

Responding to an HMRC enquiry into a historic FHL claim

The starting point is the same discipline that applies to any HMRC enquiry into a factual qualifying test: reconstructing, from contemporaneous records rather than recollection, exactly how many days the property was genuinely let, to whom, and for how long each stay ran. Platform statements, bank deposits, cleaning and changeover invoices and any booking diary are all more persuasive than an after-the-fact reconstruction. Where an election was relied on, locating the evidence that it was validly made, and made in time, is equally important. Where the underlying facts do not support the claim for a particular year, the conversation shifts to penalty behaviour, whether an honest but wrong view was taken of a genuinely borderline year, which is a materially different position from a claim made without any real attempt to track the qualifying conditions.
