An annual UK charge on enveloped homes - and for an American owner, a foreign corporation the IRS wants reported. What the structure now costs on both sides.
ATED - the Annual Tax on Enveloped Dwellings - is an annual UK charge on companies, and on certain partnerships and collective investment schemes, that hold UK residential property. GOV.UK describes it as an annual tax payable mainly by companies that own UK residential property valued at more than £500,000, and it falls due whether or not the property earns anything. For an American owner there is a second layer rarely mentioned when the structure was recommended: to the IRS that company is a foreign corporation, which brings US reporting and the anti-deferral rules into view alongside the UK charge.
For two decades an international buyer of a London house was routinely steered towards a non-UK company. The reasoning was coherent then: shares in a foreign company were not UK situs assets, so for a non-UK domiciled owner the inheritance tax exposure appeared to disappear behind the share register, and the company could be sold instead of the property.
The UK response was cumulative, and most surviving structures were built before it landed. Alongside ATED, GOV.UK states that SDLT is charged at 17% on residential properties costing more than £500,000 bought by certain corporate bodies, a rate applying since 31 October 2024.
The inheritance tax argument was then closed directly. HMRC's manual records that with effect from 6 April 2017, Schedule A1 IHTA 1984 restricts excluded property treatment to the extent that the value of an interest in a foreign close company is attributable to UK residential property. The share is still a foreign asset; the UK residential value inside it is not.
ATED is charged on the entity, not the shareholder. GOV.UK sets the entry point at UK residential property valued at more than £500,000, and the bodies in scope are companies, partnerships where any partner is a company, and collective investment schemes such as unit trusts and open-ended investment vehicles. A UK company is as capable of being caught as an offshore one, which surprises owners who assume the tax targets only foreign structures.
The charge is banded by property value, not by income or profit. For the chargeable period 1 April 2026 to 31 March 2027, GOV.UK publishes the chargeable amounts as £4,600 for property worth more than £500,000 up to £1 million, £9,450 up to £2 million, £32,200 up to £5 million, £75,450 up to £10 million, £151,450 up to £20 million, and £303,450 above £20 million. The amounts are uprated for most periods, so read any given year's figure from current guidance.
The charge also ignores the economics: a house kept for occasional family use pays the same as one fully let, unless a relief applies.
GOV.UK states that a return is due by 30 April where the property is within the scope of ATED on 1 April, or within 30 days of acquisition where it comes within scope after 1 April. Payment is not on a later timetable: HMRC states that the ATED payment date is the same as the filing date of the return, normally 30 April within the chargeable period, and that failing to pay by the deadline can attract a penalty, interest, or both. That in-year date catches dormant structures: most UK deadlines fall well after the year they relate to.
Valuation runs on a five-year cycle. GOV.UK requires revaluation every five years in line with the ATED legislation, and for the five chargeable periods from 2023-24, a property acquired on or before 1 April 2022 uses 1 April 2022 as its revaluation date, while one acquired after that date uses the acquisition date. A valuation from an earlier cycle does not carry into the next, so a structure running on autopilot may be filing against a stale figure - or, in a rising market, in the wrong band.
GOV.UK sets out relief where the property is:
Two consequences follow, and they are where families come unstuck.
Advice given before 2019 may no longer describe the disposal position. GOV.UK confirms that all non-UK resident companies, including close companies, are charged to Corporation Tax rather than Capital Gains Tax on their gains, that this applies to disposals made on or after 6 April 2019, and that the provisions relating to ATED-related Capital Gains Tax were abolished.
A gain on the house is therefore a corporate gain, reported through the company's Corporation Tax position and separate from the annual ATED charge. For property held personally, see selling UK property as a US citizen.
The IRS taxes US citizens and resident aliens on their worldwide income from all sources wherever they live, and it does not treat a property-holding vehicle as anything special. A non-US company holding a London flat is a foreign corporation.
That brings the US information regime into play. Form 5471 is described by the IRS as filed by certain US citizens and residents who are officers, directors, or shareholders in certain foreign corporations. "Directors" does real work: an American family member appointed to the board of a dormant property company, owning nothing, can acquire a filing obligation from the appointment alone. The instructions set out several categories of filer, more than one of which can apply at once, and penalties for a late or missing return are substantial and run per corporation per year. Our Form 5471 page sets out what a complete filing involves.
The anti-deferral rules can apply too. Where US persons own more than 50% of the voting power or value and a US person holds 10% or more, the company can be a controlled foreign corporation, and certain of its income is taxed to that shareholder in the year it arises even though nothing has been distributed - and rent accumulating inside the company is the kind of income those rules target. Where the control test is not met, the passive foreign investment company regime and Form 8621 may be the live analysis instead, and Form 8938 can apply on top.
The result is a mismatch in timing and in character. The company pays ATED and UK corporation tax on the UK timetable; the US owner may face an inclusion measured differently, in a different currency, on the calendar year, with credit relief that is neither automatic nor necessarily a full offset. ATED is a tax on holding property rather than on income, which makes it an uncomfortable candidate for credit against a US income tax charge - model it rather than assume it. Where property is held personally, our guide to US tax on UK rental income sets out the cleaner analysis.
The envelope was frequently sold as estate planning. For a non-US buyer holding US property there is a genuine version of that argument; for a US person holding UK property there is not.
A US citizen or US domiciliary is within the US estate tax on their worldwide estate, and shares in a property company are an asset of that estate like any other: the IRS describes estate tax as a tax on the right to transfer property at death, with includible property expressly extending to business interests. The wrapper changes what is valued, not whether it is taxed - and valuing shares in a single-asset property company, with minority and marketability arguments in play, is exactly the position that gets challenged.
On the UK side the original point is closed, as above. A structure bought to solve inheritance tax may now sit inside both systems at once, with relief depending on any applicable estate and gift tax treaty. Our article on US estate and gift tax for Americans in the UK sets out the interaction.
Sooner or later the owner asks whether to take the house out of the company. It is the right question, and it has no general answer.
Unwinding is itself a set of taxable events. On the UK side, transferring the property out can crystallise a corporate gain, extracting value can be treated as a distribution in the shareholder's hands, and the SDLT position depends on how the transfer is structured. On the US side, a distribution or liquidation of a foreign corporation is a taxable transaction with its own characterisation, basis and reporting consequences. The two systems will not agree on timing, on quantum, or on which year the tax belongs to. Against that sits the cost of doing nothing: an annual charge, an annual UK return, a US reporting stack, five-yearly valuations, and a structure whose original purpose has been legislated away.
A defensible decision is built from facts, in this order.
1. Establish what the structure is - the register, the directors, their tax status, the company's residence, and whether any US person crosses the shareholder or officer thresholds.
2. Bring UK filings current, including nil returns that should have been made under a relief.
3. Establish the US reporting position for every open year and every US shareholder, officer and director.
4. Value the property to the current ATED cycle, and quantify the latent corporate gain.
5. Model retention against de-enveloping across both systems, over a realistic holding period and the likely exit - then document the decision.
Sometimes the answer is to keep the company and file it correctly; sometimes it is to unwind. The analysis is fact-dependent, and nothing here is a recommendation to retain or unwind any particular structure.
We are usually brought in alongside a family's existing UK advisers to own the US side of a structure designed without it: running the tests on the actual register, establishing what should have been filed, and saying plainly where the two systems disagree. A licensed CPA or Enrolled Agent reviews and signs off every US filing; the UK side is reviewed by an ACCA-qualified accountant.
Our US-UK expat tax service sets out the engagement. If a UK property company has come into view, book a confidential consultation.
This article is general information, not tax or legal advice, and does not create a professional relationship. It is not a recommendation to establish, retain or unwind any structure. Outcomes are highly fact-dependent and the rules change; charges, bands and valuation dates are uprated and revised, so confirm the current position with a licensed professional before acting.
