The Annual Tax on Enveloped Dwellings (ATED) is one of the more easily overlooked taxes affecting UK property ownership. Introduced in 2013, it imposes an annual charge on UK residential property held within corporate structures — the so-called "envelope" — with values above £500,000. The purpose was to discourage the use of companies to avoid SDLT and inheritance tax on high-value residential property.
ATED affects a broad range of overseas investors, HNW individuals, and property companies. Even where a full relief from the ATED charge is available, an annual return must still be filed — failure to do so results in penalties.
What Is ATED?
ATED is a UK tax charged on UK residential property worth more than £500,000 that is owned by:
- A company (UK or overseas)
- A limited liability partnership where any member is a company
- A collective investment scheme (including certain unit trusts and OEICs)
"Residential property" for ATED purposes means a dwelling — any property that is used, or suitable for use, as a private residence. This includes:
- Furnished holiday lets
- Properties let on short-term leases (Airbnb-type arrangements)
- Properties that are unoccupied but could be used as a dwelling
- Granny annexes and gatehouse properties on larger estates
It does NOT include commercial property, hotels, student accommodation (where purpose-built), or care homes.
The Annual Charges
ATED is indexed annually by the Consumer Price Index (CPI). The charges for the current 2026/27 ATED year (1 April 2026 to 31 March 2027, set by SI 2026/156) are:
| Property Value Band | Annual ATED Charge |
|---|---|
| More than £500,000 up to £1,000,000 | £4,600 |
| More than £1,000,000 up to £2,000,000 | £9,450 |
| More than £2,000,000 up to £5,000,000 | £32,200 |
| More than £5,000,000 up to £10,000,000 | £75,450 |
| More than £10,000,000 up to £20,000,000 | £151,450 |
| Over £20,000,000 | £303,450 |
For reference, the 2025/26 charges (1 April 2025 to 31 March 2026) were: £4,450 / £9,150 / £31,050 / £72,700 / £145,950 / £292,350 for the same bands respectively.
These charges are per property, per year. A property company with ten properties across multiple bands could face a combined ATED bill of several hundred thousand pounds.
ATED Reliefs
Several reliefs are available that eliminate the ATED charge. The key reliefs are:
Genuine commercial letting relief: The most widely used relief. If the property is genuinely let on a commercial basis to a third party (i.e., a genuine tenancy at market rent to an arm's-length tenant), the ATED charge does not apply. The property must not be occupied by the owner, connected persons, or permitted occupants.
Property developer relief: Where a company develops UK residential property (builds, renovates, or refurbishes properties for sale), the property held in the course of development is exempt from ATED.
Property trader relief: Companies that purchase and sell (trade) residential properties in the course of a genuine property trading business can claim relief.
Farmhouses and farm worker accommodation: Where residential property forms part of a working farm and is occupied by a farm manager or qualifying employee, relief is available.
Charitable purposes: Charities and public bodies holding residential property for qualifying purposes.
Social housing: Housing provided by social landlords.
The Critical Compliance Trap: Filing Even When No Charge Is Due
This is the point most commonly missed by property companies and their advisers: a company that qualifies for full ATED relief is still required to file an annual ATED return.
The filing deadline is 30 April at the start of each ATED chargeable period (which runs 1 April to 31 March). An ATED return must be filed for each chargeable period in which the property is held within an envelope — even if the relief claim means the actual tax charge is nil.
Failure to file the return on time incurs:
- An automatic £100 penalty for late filing
- Further daily penalties after three months
- Additional penalties after six and twelve months
HMRC has issued penalty notices to many property companies that were unaware of the requirement to file nil-charge returns. Property companies using relief must still file.
Valuation for ATED
The property value used for ATED is the market value at a revaluation date, not the original purchase price. Revaluation dates occur every five years:
- The most recent revaluation date was 1 April 2022
- The value used for 2022/23 through 2026/27 ATED returns is the market value at 1 April 2022 (or the most recent acquisition date if later)
- The next revaluation date will be 1 April 2027
A property purchased for £450,000 in 2015 that has grown in value to £600,000 by 1 April 2022 will be drawn into the £500,001–£1,000,000 ATED band from the 2022/23 chargeable period onwards, even though it was below the threshold at acquisition.
It is the company's responsibility to value the property at each revaluation date and determine whether the ATED threshold has been breached. Formal RICS valuations are not mandatory but provide evidence if HMRC challenges the valuation. An error in undervaluing a property below an ATED threshold could lead to an ATED assessment plus penalties.
ATED and Related Property Taxes
ATED sits within a broader framework of property taxes specifically targeting corporate ownership of UK residential property:
Higher SDLT rates (15% flat rate): Purchases of UK residential property by companies at values above £500,000 incur a 15% flat SDLT rate (unless a relief applies). This significantly increases the acquisition cost for company purchases.
Non-resident CGT: Companies not resident in the UK are subject to CGT (at the corporation tax rate) on disposal of UK residential and commercial property.
ATED-related CGT: Gains on ATED-chargeable properties are taxed under a separate regime if the ATED charge applied in the year of disposal. This can interact with the standard non-resident CGT rules.
UK IHT on UK-sited assets: UK residential property held within a non-UK company may still be within the scope of UK IHT if the beneficial owner is UK domiciled or a long-term UK resident. Even for non-UK domiciliaries, UK-sited assets (which includes shares in a company if the company's value derives from UK property) may be in scope.
The De-Enveloping Problem
Many properties were placed into corporate structures before 2013 — when the ATED regime was introduced — for tax and estate planning reasons. The question of whether to "de-envelope" (remove the property from the corporate structure) is complex and rarely straightforward.
The costs of de-enveloping:
Removing a property from a company can trigger:
- SDLT: Transferring the property from the company to an individual shareholder is a chargeable transaction for SDLT purposes if the property has grown in value. The market value is used as the consideration even if no money changes hands.
- CGT (or corporation tax on the gain): The company pays corporation tax on the gain from the original acquisition cost to the market value at transfer. The individual may also have a further CGT liability on eventual disposal.
- Income tax: If the transfer is treated as a distribution from the company (e.g., a benefit in kind or dividend), income tax may apply.
The costs of keeping the envelope:
- Annual ATED charges (if relief not available)
- Higher rates of SDLT on any future restructuring
- Complexity and ongoing compliance costs
- The 15% SDLT rate on any subsequent corporate purchase
The conclusion: De-enveloping almost always creates significant tax charges and should only be done with specialist tax advice. For properties where a full ATED relief applies and the relief will continue indefinitely (e.g., a genuine commercial let), keeping the structure may be less costly than de-enveloping, once the tax trigger costs are considered.
ATED for Overseas Companies
Overseas companies that own UK residential property above £500,000 are within scope of ATED. There is no exemption for offshore structures. This was an explicit policy decision to address the practice of holding UK prime residential property through offshore companies (particularly in Jersey, BVI, and Cayman Islands) to avoid SDLT and IHT.
Overseas companies are required to register for ATED through HMRC's online services and file returns in the same way as UK companies.
Planning Points
- Confirm relief eligibility annually. If the nature of the property use changes (e.g., a previously commercially let property is now used by the owner's family), relief will no longer apply and the full ATED charge becomes due.
- File on time, always. Even if the tax charge is nil. The 30 April deadline must be met for each property in each chargeable period.
- Revalue at revaluation dates. Ensure the 1 April 2022 (and future 2027) market values are correctly assessed. Properties that have grown significantly may have moved into higher bands.
- Consider the broader tax package before acquiring. The combination of 15% SDLT, ATED, and non-resident CGT makes corporate ownership of UK residential property expensive. New corporate acquisitions of UK residential property should be structured only after a full tax analysis.
Compliance Caveats
ATED rules, rates, and relief conditions are subject to change. The charges stated in this article reflect published 2026/27 rates (SI 2026/156) and should be verified against current HMRC guidance before any transaction or return preparation. This article is for information only and does not constitute tax advice. Professional advice from a qualified UK tax adviser is essential for anyone holding or considering holding UK residential property through a company. Property values can fall as well as rise; income is not guaranteed.
