For over 40 years, owners of qualifying furnished holiday lets enjoyed a set of tax advantages that put them closer to businesses than to ordinary residential landlords. That era came to an end on 6 April 2025. From that date, income from short-term holiday letting — whether through Airbnb, direct bookings, or any other channel — is taxed as standard UK property income under the same rules that apply to long-term residential landlords.

The change was first announced by then Chancellor Jeremy Hunt at the Spring Budget in March 2024, and was subsequently confirmed and carried forward by the incoming Labour government. There is no transitional period for income tax purposes and no grandfathering for existing properties.

⚠️ Important — your 2025/26 return

The 2025/26 tax return, due 31 January 2027, is the first return filed entirely under the post-FHL rules. For many holiday let owners, particularly those with mortgage debt on their properties, the tax bill for 2025/26 will be materially higher than 2024/25. If you haven't already reviewed your position, now is the time.

What the FHL regime was

Before 6 April 2025, a residential property qualified as a Furnished Holiday Let if it met three occupancy conditions:

Properties meeting these conditions were treated as a trading business, not an investment property, and received significant tax advantages not available to ordinary residential landlords.

What has changed — the full picture

Tax treatment Before 6 April 2025 (FHL) From 6 April 2025 (standard)
Mortgage interest Fully deductible from rental income Section 24 applies — 20% tax credit only
Capital allowances Annual Investment Allowance & capital allowances on furniture, fixtures and fittings No new capital allowances — Replacement of Domestic Items Relief only (like-for-like)
CGT — Business Asset Disposal Relief Available on sale — 10% CGT rate No longer available — standard 18%/24% residential CGT rates apply
CGT — Rollover relief Available where proceeds reinvested in another qualifying asset No longer available
CGT — Gift relief Available on gifts of FHL properties No longer available
Pension contributions FHL profits counted as relevant earnings — could fund pension contributions Holiday let profits no longer count as relevant earnings
Losses FHL losses could be offset against other FHL income in same year Losses form part of property business — offset against other property income only
Income splitting Profits could be split between co-owners in any proportion Standard property rules apply — usually split in proportion to ownership

The biggest change — mortgage interest restriction

For most holiday let owners with a mortgage, this is the change that hurts most. Under Section 24, mortgage interest is no longer deductible as a business expense. Instead, you receive a 20% tax credit on mortgage interest costs.

This is the same restriction that was phased in for residential landlords between 2017 and 2020 — but holiday let owners were previously exempt from it entirely. That exemption is now gone.

Worked example — higher rate taxpayer

Annual rental income£24,000
Annual mortgage interest£12,000
Other expenses£4,000
Under old FHL rules (2024/25)
Taxable profit (after full interest deduction)£8,000
Tax at 40%£3,200
Under new rules (2025/26 onwards)
Taxable profit (interest no longer deductible)£20,000
Tax at 40%£8,000
Less 20% tax credit on interest (£12,000 × 20%)-£2,400
Net tax payable£5,600
Additional tax compared to 2024/25+£2,400/year

For a 40% higher rate landlord with £30,000 of annual mortgage interest, that is a £6,000 a year increase in net tax compared with the old FHL position.

Limited companies are not affected by Section 24

Limited companies are not in scope of Section 24, so company-held holiday lets still get full mortgage interest deduction inside the company. Whether incorporating is worthwhile depends on a range of factors — it is not a straightforward decision and should be reviewed carefully with an accountant before any action is taken.

Capital allowances — what you can and can't claim

Under the old FHL regime, owners could claim the Annual Investment Allowance and capital allowances on furniture, fixtures, fittings and equipment. From 6 April 2025 you cannot bring new qualifying expenditure (new fridge, new sofa, new heat pump, new fitted carpets) into a capital allowances pool for a holiday let.

However, the situation for existing pools is slightly different. There are some specific transitional rules available: continuation of ongoing capital allowances pools of historical expenditure — however, any new expenditure incurred on or after the operative date must be considered under the property business rules.

Going forward, Replacement of Domestic Items Relief (RDIR) applies instead. This allows you to deduct the cost of replacing an existing domestic item (sofa, bed, white goods) on a like-for-like basis — but it does not cover initial fit-out, improvements to existing items, or the cost of items above a like-for-like replacement standard.

Capital Gains Tax — significant loss of reliefs

FHL properties previously enjoyed a suite of CGT reliefs that treated them like business assets rather than investment properties. All of these are now gone:

CGT timing — contracts vs completion

The tax point for CGT is exchange of contracts. If you exchanged on or before 5 April 2025 (even with completion after), the old rules apply to that disposal. Get the contract date confirmed before filing. If you are in any doubt about the applicable rules for a disposal, seek advice before submitting your return.

Pension contributions

One of the less-discussed but significant changes is the impact on pension planning. Under the old regime, FHL profits counted as "relevant earnings" for pension purposes, allowing holiday let owners to make tax-relieved pension contributions up to 100% of those profits (subject to the annual allowance). Profits from FHLs counting as relevant earnings for pension purposes meant tax-advantaged pension contributions could be made.

From 6 April 2025, holiday let profits are property income — not relevant earnings — and cannot be used to support pension contributions in the same way. If you were relying on FHL income to fund pension contributions, your maximum pension input may have reduced significantly. This should be reviewed urgently if you have an ongoing pension contribution strategy based on FHL income.

Anti-forestalling rules

There is also an anti-forestalling rule that applies from 6 March 2024, which prevents the obtaining of a tax advantage through the use of unconditional contracts to obtain capital gains relief under the current FHL rules. If you did any pre-abolition restructuring, get advice on whether the anti-forestalling provisions catch your transaction.

What should you do now?

The immediate priority for most holiday let owners is understanding the impact on your 2025/26 self-assessment return, due 31 January 2027. Beyond that, some owners will want to review their longer-term strategy.
