Why the End of Furnished Holiday Lettings Matters to American Owners
The special tax regime for furnished holiday lettings ended on 6 April 2025, and the first self-assessment return filed entirely under the new rules is due by 31 January 2027. Consequently, the 2025/26 tax year is the moment the abolition stops being theoretical and starts costing real money. Most commentary published so far was written in 2024, in the future tense, before anyone had filed anything.
Furthermore, almost all of that commentary ignores a group of owners who face a second, entirely separate problem. American citizens and green card holders who own a cottage in Cornwall, a mews house in Bath or a lodge in the Highlands must also report that property to the IRS. Therefore the UK changes do not simply raise a UK tax bill. Instead, they reshape the interaction between two tax systems that were never designed to fit together.
At TaxYork, we prepare cross-border returns for high-net-worth clients whose property portfolios straddle the Atlantic. In our experience, the owners hit hardest are not the ones who read about the abolition. Rather, they are the ones who assumed their UK accountant and their US preparer were talking to each other.
What Furnished Holiday Lettings Status Actually Gave You
Qualifying furnished holiday lettings were treated as a trade rather than an investment, which unlocked four valuable advantages. Specifically, owners deducted mortgage interest in full, claimed capital allowances on furniture and fixtures, counted profits as relevant UK earnings for pension relief, and accessed the business capital gains reliefs on sale.
To qualify, a property had to be available for letting for at least 210 days a year and actually let commercially for at least 105 days. Additionally, lettings exceeding 31 continuous days could not exceed 155 days in aggregate. Averaging and period-of-grace elections softened the edges for owners with several properties.
Notably, that entire architecture has gone. HMRC confirmed the position in its policy paper on abolition of the furnished holiday lettings tax regime, and issued a follow-up clarification on the abolition dealing with transitional questions.
The Furnished Holiday Lettings Dates That Now Govern Your Filing
Income tax and capital gains tax changes took effect from 6 April 2025. Meanwhile, corporation tax and corporation tax on chargeable gains changed from 1 April 2025. Importantly, an anti-forestalling rule has applied since 6 March 2024, well before either commencement date.
Your property is now simply part of an ordinary UK property business. Accordingly, HMRC's guidance on working out your rental income governs the computation, and HM Revenue and Customs applies the same rules it applies to a buy-to-let flat in Leeds.
The Four Furnished Holiday Lettings Reliefs You Have Now Lost
Losing furnished holiday lettings treatment removes four distinct advantages, and each one bites differently depending on how you hold and finance the property. Moreover, the combined effect on a leveraged higher-rate taxpayer is considerably worse than any single change suggests.
Finance Cost Relief Restricted to Basic Rate
Mortgage interest was previously a full deduction against rental profit. However, relief now arrives as a 20% tax credit, exactly as it does for ordinary landlords since 2017. For an additional-rate taxpayer, effective relief falls from 45% to 20%.
Consider the arithmetic on £30,000 of annual interest. Previously that saved £13,500 in tax at 45%. Now it saves £6,000. Consequently, the annual cost of the change alone reaches £7,500 before any other adjustment.
Additionally, the restriction inflates your taxable profit, because interest no longer reduces it. Therefore some owners of furnished holiday lettings find themselves pushed into a higher rate band, or losing personal allowance, purely as a result of the presentational change.
Capital Allowances Replaced by Domestic Items Relief
New expenditure on furniture, white goods and fixtures no longer attracts capital allowances. Instead, you claim replacement of domestic items relief, which covers like-for-like replacements only. Crucially, that relief gives nothing for the initial fit-out of a newly acquired property.
Existing capital allowance pools continue to unwind under the transitional rules. Nevertheless, the practical effect for furnished holiday lettings refurbished to compete on quality is severe. A £60,000 refit that once generated immediate relief now generates none until items are replaced.
Pension Relevant Earnings Disappeared
Profits from furnished holiday lettings previously counted as relevant UK earnings, allowing owners to contribute to a pension and claim tax relief on that basis. That has stopped. Therefore owners whose only substantial UK earnings came from holiday lets have lost their pension funding capacity entirely.
This point creates a genuine trap. Specifically, an owner who continued contributing at previous levels during 2025/26 may face an excess contribution charge. Accordingly, we recommend reviewing contributions made since April 2025 before the return is filed.
Capital Gains Tax After the Furnished Holiday Lettings Abolition
The capital gains position is where the largest sums sit, and where the published guidance is most out of date. Furthermore, one valuable window remains open, but it closes in April 2028.
Business Asset Disposal Relief and the Closing Three-Year Window
Business Asset Disposal Relief no longer applies to furnished holiday lettings. However, a transitional provision preserves it where the qualifying conditions were satisfied before repeal and the disposal falls within the standard three-year post-cessation window. Because the business is treated as ceasing on 5 April 2025, that window runs to 5 April 2028.
Almost every competing article still quotes the relief at 10%. That figure is wrong now. The rate rose to 14% for disposals between 6 April 2025 and 5 April 2026, and it stands at 18% for disposals on or after 6 April 2026, as GOV.UK confirms for Business Asset Disposal Relief.
Consequently, the transitional window is worth far less than it was, though it is not worthless. Standard residential rates remain 18% for basic rate taxpayers and 24% above that, per the capital gains tax rates guidance. Therefore a higher-rate owner selling before April 2028 still saves six percentage points.
The Anti-Forestalling Rule From 6 March 2024
HMRC anticipated owners exchanging unconditional contracts early to lock in the old reliefs. Hence the anti-forestalling rule, which has applied since 6 March 2024 and is explained in HMRC's Capital Gains Manual at CG64174. Where the rule bites, the relief is denied.
Importantly, the rule targets arrangements whose main purpose was obtaining the tax advantage. Genuine commercial sales are unaffected. Nevertheless, any owner who exchanged in spring 2024 and completed later should expect HMRC to ask why.
Rollover and Gift Relief Are Gone
Rollover relief allowed owners to defer gains by reinvesting in other business assets. Similarly, gift relief allowed a transfer without an immediate charge. Both have been withdrawn for furnished holiday lettings, alongside relief for loans to traders.
For American owners, the withdrawal of gift relief matters twice over. Firstly, the UK charge crystallises on transfer. Secondly, a gift by a US person may trigger a Form 709 filing obligation regardless of the UK outcome.
Furnished Holiday Lettings: The American Layer UK Advisers Miss
Here the mainstream UK guidance simply stops. Yet for a US citizen, the UK abolition changes the size of the foreign tax credit, not the existence of a US filing obligation. Furthermore, the US rules applying to furnished holiday lettings differ sharply from the US rules for ordinary rentals.
Schedule E, ADS Depreciation and the Thirty-Year Life
Your UK holiday let belongs on Schedule E of Form 1040 unless it is genuinely a business. Additionally, foreign rental property must be depreciated under the Alternative Depreciation System, using straight-line depreciation over 30 years for property placed in service after 31 December 2017, and 40 years for earlier acquisitions.
That contrast matters. A domestic US rental depreciates over 27.5 years, so your UK cottage generates markedly less annual depreciation than an equivalent property in Florida. IRS Publication 527 sets out the residential rental rules in full.
Moreover, depreciation is not optional. If you never claimed it, the IRS still reduces your basis on sale by the amount you were allowed to claim. Therefore unclaimed depreciation creates gain without ever having created a deduction.
The Seven-Day Rule That Can Make Your Let Non-Passive
This is the single most valuable point for American owners, and no UK competitor covers it. Under Treasury Regulation 1.469-1(e)(3)(ii)(A), an activity is not a rental activity where the average period of customer use is seven days or less. Consequently, a genuine holiday let with short average stays escapes the automatic passive classification.
If you also materially participate under one of the seven tests in Regulation 1.469-5T(a), the activity becomes non-passive. Accordingly, losses can offset other income rather than being suspended. For a high-net-worth owner with substantial employment or investment income, that treatment is worth a great deal.
Notably, the UK abolition strips trading status away from furnished holiday lettings while the US rules may still treat the same property as a business. Furthermore, that divergence is now wider than it has ever been, which creates planning opportunities that did not previously exist.
Self-Employment Tax and the Net Investment Income Tax
Non-passive treatment carries a warning. Where you provide substantial services comparable to a hotel, the income may attract self-employment tax. However, the US-UK totalisation agreement generally protects a UK-resident owner already paying National Insurance.
Conversely, passive rental income falls within the net investment income tax at 3.8%. Critically, foreign tax credits cannot offset that charge. Therefore an owner paying substantial UK tax can still face a residual 3.8% US liability on the same profit.
Foreign Tax Credits, Currency and the Mismatched Tax Years
Relief from double taxation depends on claiming credits correctly, and holiday lets present two structural problems that ordinary employment income does not.
Why Your UK Tax Year Will Never Match Your US Return
The UK tax year runs to 5 April while the US tax year ends on 31 December. Consequently, you cannot simply copy figures across. Instead, you must recompute the property result on a calendar-year basis and convert each entry to US dollars.
Additionally, UK tax paid on the 2025/26 year is not paid until January 2027. Therefore accrual and cash-basis credit elections produce materially different answers, and the choice binds you going forward.
Which Basket Your Holiday Let Income Falls Into
Rental income is normally passive category income for foreign tax credit purposes, reported on Form 1116. However, income from an active trade or business falls into the general category instead.
Because the seven-day rule can push a holiday let towards business treatment, basket selection requires genuine analysis. Moreover, credits in one basket cannot relieve tax in another. Hence a mistake here strands credits that you have genuinely paid for.
Reporting Obligations on Furnished Holiday Lettings Beyond the Tax Return
Owning UK furnished holiday lettings generates information reporting that has nothing to do with profit. Furthermore, the penalties for missing these forms dwarf the tax at stake.
FBAR and the Letting Agent's Client Account
If your UK accounts exceeded $10,000 in aggregate at any point, you must file an FBAR. Importantly, this includes the deposit account holding guest payments, and sometimes an account over which your letting agent gives you signature authority.
Owners routinely overlook these. Additionally, an account you never personally opened still counts if you hold a financial interest or signature authority over it.
Form 8938 and Ownership Through a UK Company
Holding the property through a UK limited company converts a simple problem into a complex one. Specifically, you become a shareholder in a controlled foreign corporation, triggering Form 5471 and potential GILTI exposure. Meanwhile, the shares themselves may require reporting on Form 8938.
The property itself is not reportable on Form 8938 when held directly. However, the moment a company or partnership sits between you and the bricks, the position changes entirely. Our FBAR and FATCA service addresses exactly this analysis.
What to Do If You Never Reported the Let at All
Many owners bought a holiday cottage years ago and simply never mentioned it to their US preparer. Consequently, they have missed US tax returns, missed FBAR filings and missed reporting of a foreign asset. That combination sounds alarming, yet a well-established remedy exists.
The IRS Streamlined Filing Compliance Procedures allow non-wilful taxpayers to file three years of returns and six years of FBARs, with no penalty under the foreign offshore route. Therefore acting voluntarily, before HMRC or FATCA data reaches the IRS, remains far cheaper than waiting. Our IRS Streamlined Filing service handles the full submission.
A Worked Case Study: Cornwall Furnished Holiday Lettings in 2025/26
Consider Charlotte, a dual US-UK national and an investment banker in London. She owns a four-bedroom property near Padstow, bought in 2016 for £520,000 and now worth £820,000. Her mortgage stands at £390,000 at 5%, producing £19,500 of annual interest. Gross letting income for 2025/26 was £68,000, with £21,000 of running costs.
The UK Position Before and After
Under the old rules, Charlotte deducted the full £19,500 of interest, leaving a profit of £27,500 and a tax bill of £12,375 at 45%. Under the new rules, her taxable profit becomes £47,000, taxed at £21,150, reduced by a basic-rate credit of £3,900. Her UK liability therefore rises to £17,250, an increase of £4,875 in a single year.
Additionally, she had planned a £40,000 pension contribution supported by her furnished holiday lettings profits. That capacity has gone, because those profits are no longer relevant UK earnings.
The US Position and the Net Result
On the US side, Charlotte reports the property on Schedule E in dollars. Her average guest stay is five nights, so the seven-day rule applies and the activity is not automatically passive. Because she materially participates through her management of bookings and refurbishment, the income sits outside the 3.8% net investment income tax.
ADS depreciation on a £400,000 building element over 30 years gives roughly £13,300 a year. Consequently, her US taxable profit is considerably lower than her UK figure, and her UK tax of £17,250 fully covers the residual US liability. Ultimately, Charlotte owes no additional US tax, but she must still file, and she must still claim the credits correctly to prove it.
If she sells before 5 April 2028, the transitional Business Asset Disposal Relief saves six points on the first £1m of gain. On a £300,000 gain, that is £18,000. Waiting until April 2028 therefore costs her that sum outright.
How TaxYork Can Help
We prepare US and UK returns together, in one place, for clients whose affairs cross both systems. Furthermore, we model the interaction rather than filing two disconnected returns and hoping the credits align.
Specifically, we recompute the furnished holiday lettings result on both tax years, select the optimal foreign tax credit basket, and test whether the seven-day rule improves your position. Additionally, we review the transitional relief window before it closes and quantify the cost of delay. Where reporting has been missed, we bring you current through the appropriate disclosure route.
Our US tax return preparation for expats and tax treaty optimisation services work together for exactly these situations. Moreover, we deal with HMRC and the IRS directly, so you do not have to.
Conclusion
The abolition of furnished holiday lettings status has permanently changed the economics of UK holiday property. Leveraged owners lose the most, pension capacity has vanished, and the capital gains reliefs close for good on 5 April 2028. Therefore the decisions you make in the next eighteen months carry real financial consequences.
For American owners, the picture is more nuanced than the headlines suggest. Notably, the US seven-day rule can still deliver business treatment that the UK has withdrawn. Consequently, coordinated advice now produces outcomes that neither a UK accountant nor a US preparer can reach alone. Additionally, Making Tax Digital obligations under HMRC's guidance for income tax add a further layer for qualifying landlords.
