Annual Tax on Enveloped Dwellings (ATED): What Companies Owning Residential Property Must Know

Section 24 has pushed more landlords than ever into buying and holding property through a company. What a lot of them do not budget for is a separate annual tax that applies purely because a company — rather than an individual — owns a residential dwelling worth more than half a million pounds. It is called the Annual Tax on Enveloped Dwellings, it is easy to miss until the first bill or penalty notice arrives, and one of its most common traps has nothing to do with property value at all.

What ATED actually is

ATED is an annual charge on UK residential dwellings valued above £500,000 that are owned by a “non-natural person” — in practice, almost always a UK or overseas company, a partnership with a corporate member, or a collective investment scheme. It does not apply to individuals owning property directly, however many properties they hold. It applies dwelling by dwelling: a company holding three qualifying properties gets three separate charges, not one combined assessment.

The chargeable period runs 1 April to 31 March. Valuation is self-assessed by the company, based on the property's value at a fixed valuation date rather than its current market value — the current valuation date is 1 April 2022 (or the acquisition date, if later), and it holds for the five chargeable periods from 2023/24 through to 2027/28. The next revaluation date is 1 April 2027, taking effect from 2028/29. This means a property bought for £480,000 in 2023 that is now worth £550,000 on the open market may still sit outside ATED entirely, because it is the fixed valuation date that counts — but it also means values need re-checking as each new five-year cycle approaches.

What it costs

The charge is banded by value and uprated each year, broadly in line with inflation. For the 2026/27 period (1 April 2026 to 31 March 2027), the annual charge is:

• £500,001 – £1,000,000: £4,600
• £1,000,001 – £2,000,000: £9,450
• £2,000,001 – £5,000,000: £32,200
• £5,000,001 – £10,000,000: £75,450
• £10,000,001 – £20,000,000: £151,450
• Above £20,000,000: £303,450

Because these figures move every year, the charge that applied when a company first bought a property is not necessarily what is due this year — it is worth checking the current band each time a return is prepared, not assuming last year's figure still applies.

Filing and payment deadlines

For a property already within scope at the start of a chargeable period, the return and payment are due by 30 April at the start of that period — effectively a pre-payment for the year ahead, not paid in arrears. Miss this and HMRC treats it the same as any other late Self Assessment-style filing: penalties start immediately, escalate the longer the return remains outstanding, and run alongside interest on any unpaid tax.

Two situations sit outside the standard 30 April date. If a company acquires a qualifying dwelling, or an existing property newly comes into scope (a change of use, for example), a return is due within 30 days. For a new build, the deadline is 90 days from whichever comes first — the date it becomes a dwelling for council tax purposes, or the date it is first occupied. Developers holding new stock need this date diarised separately from the main annual cycle, since it will not align with the 30 April deadline most other property owners are working to.

Reliefs exist — but they are not automatic

Several reliefs reduce the ATED charge to nil, and they cover most of the ordinary reasons a company might hold residential property:

• Property rental business relief — the property is let to a third party on a genuinely commercial, arm's-length basis.
• Property developer or trading stock relief — the dwelling is held for development or resale in the course of a property development or trading business.
• Employee occupation relief — a trading company provides the dwelling to a genuine employee for the purposes of the trade (with restrictions where the employee is also a significant shareholder).
• Farmhouse relief, relief for dwellings open to the public, and relief for charitable, public sector and social housing bodies.

None of these apply by default. Even where relief reduces the liability to nil, the company must still submit an annual return or a Relief Declaration Return by the deadline to claim it. This is the single most common way ATED penalties arise: not because tax was owed and unpaid, but because a company assumed relief meant no filing obligation, and a penalty notice arrived for a return that was never made.

The trap most SPV owners do not see coming

This is worth stating plainly, because we see it regularly among landlords and investors who have incorporated since Section 24 restricted mortgage interest relief for individuals: buying a high-value home through your own company for you, a family member, or another shareholder to live in does not qualify for property rental business relief. That relief requires a commercial letting to someone unconnected with the company. A director living in a company-owned house, rent-free or on non-commercial terms, is exactly the scenario the connected-party rule is designed to catch.

The consequences stack. ATED is due in full, at the appropriate band, every year the arrangement continues. Separately, HMRC treats a close company providing living accommodation to a director or shareholder as a benefit in kind, taxable on the individual, with its own reporting and Class 1A National Insurance consequences for the company. Neither of these is a one-off cost that fades after the first year — both recur annually for as long as the arrangement stands. This is one of the clearest examples of a structure that looks efficient on the SDLT and Section 24 numbers alone, but is materially worse once ATED and benefit-in-kind rules are factored in — exactly the kind of interaction we cover when weighing up whether company ownership actually stacks up for a given property.

Where this sits alongside SDLT and CGT

ATED is separate from, and in addition to, the 5% SDLT surcharge a company pays on acquiring residential property, and separate again from the corporation tax due on any eventual gain when the property is sold (the old standalone ATED-related CGT charge was abolished for disposals from April 2019, folded into the wider extension of UK tax to company and non-resident disposals of UK property). None of these three replace each other — a company holding a £600,000 investment property faces the surcharge on the way in, ATED every year it is held (unless relief genuinely applies), and tax on the gain on the way out. Modelling only one of the three, and assuming the others will not apply, is how the true cost of a company structure gets underestimated.

What to do if this affects you

If your company holds — or is about to buy — a UK residential dwelling anywhere near the £500,000 threshold, the questions worth answering before the next 30 April deadline are: what is the property's value at the current valuation date, does the letting genuinely qualify for relief, and has a return (even a nil-liability Relief Declaration Return) actually been filed. Getting the relief claim right, and getting it filed on time, is a considerably smaller job than untangling penalties and a benefit-in-kind enquiry after the fact.

Common questions

What is ATED and which properties does it apply to?

The Annual Tax on Enveloped Dwellings is an annual charge on UK residential dwellings valued above £500,000 that are owned by a “non-natural person” — typically a UK or overseas company, a partnership with a corporate member, or a collective investment scheme. It applies dwelling by dwelling, not to the company's portfolio as a whole, so each qualifying property is assessed and charged separately.

What is the ATED threshold and how much does it cost?

The entry threshold is £500,000 of property value. For the 2026/27 chargeable period (1 April 2026 to 31 March 2027), the annual charge ranges from £4,600 for a property valued between £500,001 and £1 million, rising through several bands to £303,450 for a property valued above £20 million. The charges are uprated broadly in line with inflation each year, so the figure due changes annually even if nothing else about the property does.

Can I avoid ATED by claiming relief, and do I still need to file if no tax is due?

Several reliefs reduce the charge to nil, most commonly for a genuine property rental business letting to an unconnected third party on commercial terms, for property developers holding a dwelling as trading stock, and for dwellings occupied by employees of a qualifying trading company. None of these are automatic. A return, or a Relief Declaration Return, must still be submitted by the deadline to claim the relief — failing to file attracts the same penalties as failing to pay tax that was actually due.

Does ATED apply if a director lives in a property owned by their own company?

Yes, and this is where ATED catches out the most property owners. The property rental business relief only applies to lettings on genuinely commercial terms to someone unconnected with the company. A director or shareholder living in a company-owned home does not qualify, however the arrangement is structured, so the full ATED charge is due. On top of that, HMRC treats the arrangement as the company providing living accommodation to a participator, which brings its own benefit-in-kind and corporation tax consequences separate from ATED.
