ATED

The Annual Tax on Enveloped Dwellings (ATED) catches many companies unaware, and with 2026/27 charges running from £4,600 to £303,450 a year, a missed relief claim is expensive. Acumon handles the full cycle: liability assessment, relief declaration returns, charge calculations and payment planning — alongside the SDLT, capital gains and corporation tax issues that come with 'enveloped' property.

What is ATED?

ATED (Annual Tax on Enveloped Dwellings) is an annual charge on UK residential property worth more than £500,000 held by 'non-natural persons' — companies, partnerships with a corporate member and collective investment schemes. Introduced in 2013 to discourage 'enveloping' high-value homes in corporate structures, it applies for each chargeable period running 1 April to 31 March.

Crucially, even where a relief removes the charge entirely, a return normally still has to be filed. That is the most common ATED mistake we see — and penalties apply to late returns even when no tax is due.

ATED Charge Bands and Rates (2026/27)

Properties valued at £500,000 or less are outside ATED. For the chargeable period 1 April 2026 to 31 March 2027 the annual charges are:

£500,001 to £1 million: £4,600 £1 million to £2 million: £9,450 £2 million to £5 million: £32,200 £5 million to £10 million: £75,450 £10 million to £20 million: £151,450 Over £20 million: £303,450

The return and payment for 2026/27 were due by 30 April 2026 for properties held on 1 April 2026. Properties acquired part-way through the year trigger their own filing deadline shortly after purchase, with the charge apportioned for the period of ownership.

ATED Reliefs

Most commercially held property qualifies for a relief — but every relief has conditions, and each must be claimed on a return.

Property Rental Business Relief: for property let on a commercial basis to unconnected third parties as part of a genuine rental business.

Property Development and Property Trading Relief: for property acquired to develop and resell, or held as trading stock, provided it is not occupied by a connected person.

Dwellings Open to the Public Relief: for properties opened to the public on a commercial basis for a minimum number of days each year, such as historic houses.

Farmhouse Relief: for a farmhouse forming part of a working farm and occupied by a qualifying farm worker.

Employee Accommodation Relief: for accommodation provided for the company's trade to employees who are not connected persons.

We review actual use against the conditions each year — occupation by a shareholder or family member, a void period or a change of intention can all put a relief at risk.

Our ATED Services

Compliance and return preparation: liability assessment across your portfolio, preparation and submission of ATED returns and relief declaration returns by 30 April, and ongoing monitoring as circumstances change.

Relief assessment: a structured review of property use, letting arrangements, development activity and occupation to confirm which reliefs apply and that the evidence supports them.

Charge calculations: banding reviews, charge calculations where reliefs don't apply, apportioned calculations for part-year ownership, and payment planning.

Strategic planning: ownership structuring, transaction timing, and integration with SDLT, CGT and corporation tax — including whether keeping the property in a corporate wrapper still makes commercial sense.

Deadlines and Penalties

ATED works on a 'pay in advance' cycle: the return and any payment are due by 30 April at the start of each chargeable period (1 April to 31 March).

Late returns attract an immediate fixed penalty, with daily and tax-geared penalties the longer the return remains outstanding — and they apply even where a relief means no ATED is actually payable. We diarise every deadline so returns are filed on time, every time.

Property Valuations for ATED

Your charge band depends on the property's value at the later of the most recent fixed five-yearly ATED revaluation date or the date you acquired it. If your property sits near a band boundary, a professional valuation matters — and we can support a pre-return banding check with HMRC to give certainty before you file.

ATED and Other Property Taxes

ATED rarely exists in isolation. Companies buying residential property for more than £500,000 can also face the flat 17% SDLT rate for corporate purchasers (with reliefs that broadly mirror the ATED reliefs). Disposals need CGT and corporation tax coordination, and ATED charges are generally deductible for corporation tax purposes. We advise on the whole picture, not just the return.
