For companies and other corporate entities owning high-value UK residential property, Annual Tax on Enveloped Dwellings (ATED) is a compliance obligation that cannot be overlooked. Introduced in 2013 to discourage the use of corporate structures as a vehicle for property tax avoidance, ATED applies an annual charge to qualifying properties and carries significant penalties for late or incorrect filing. This guide explains who it applies to, how it is calculated, what reliefs are available, and what the current deadlines and rates are.
What Is Annual Tax on Enveloped Dwellings?
ATED is an annual tax charged on UK residential properties valued at more than £500,000 that are owned by “non-natural persons” (NNPs). The term “non-natural person” refers to any entity that is not an individual, most commonly a UK or overseas company, a partnership with at least one corporate member, or a collective investment scheme such as a unit trust or open-ended investment vehicle (OEIV).
The tax was introduced by the Finance Act 2013, Part 3, with the primary aim of combating anti-avoidance schemes that allowed high-value properties to be sold via share transfers, thereby avoiding Stamp Duty Land Tax. It also promotes transparency by requiring corporate bodies to declare ownership of high-value residential property and contribute fairly to the tax system.
ATED is self-assessed and operates on a forward-looking basis, meaning returns are filed and tax paid at the start of the chargeable period rather than after it ends.
What Properties Does ATED Apply To?
A property falls within ATED if all or part of it is used, or capable of being used, as a single residence (for example a house or flat), and it is owned by a non-natural person. The definition of a dwelling includes any gardens, grounds, and buildings within them, such as garages, swimming pools, tennis courts, summerhouses, and driveways.
Where a building contains multiple self-contained dwellings with no private access between them, each unit is treated separately for ATED purposes. Where a property has mixed residential and non-residential use, only the value of the residential part is assessed.
Certain types of properties are specifically excluded from the definition of a dwelling and therefore fall outside ATED entirely:
- Hotels and guest houses
- Boarding school accommodation
- Student halls of residence
- Hospitals, hospices, and care homes
- Military accommodation
- Prisons
ATED Charges: Current Rates
The ATED charge is based on a banding system using the value of each individual dwelling. The rates increase annually in line with the Consumer Prices Index (CPI). The current rates for both the 2025 to 2026 and 2026 to 2027 chargeable periods are as follows:
| Property Value | 2025 to 2026 Annual Charge | 2026 to 2027 Annual Charge |
| More than £500,000 up to £1 million | £4,450 | £4,600 |
| More than £1 million up to £2 million | £9,150 | £9,450 |
| More than £2 million up to £5 million | £31,050 | £32,200 |
| More than £5 million up to £10 million | £72,700 | £75,450 |
| More than £10 million up to £20 million | £145,950 | £151,450 |
| More than £20 million | £292,350 | £303,450 |
Where a property is acquired part way through the ATED year, or a relief applies for only part of the year, the charge is apportioned on a daily basis.
Valuing Your Property for ATED
The value used to determine which ATED band applies is based on the property’s market value on a fixed valuation date, not necessarily its current market value. Properties are revalued every five years. The current revaluation date is 1 April 2022, which applies for all chargeable periods from 2023 to 2024 through to 2027 to 2028. Properties acquired after 1 April 2022 use the date of acquisition as their valuation date.
The next five-year revaluation date will be 1 April 2027, applying from the 2028 to 2029 chargeable period onwards.
A revaluation is also triggered before the next scheduled date if a substantial acquisition or disposal of part of the dwelling occurs, meaning the chargeable consideration is £40,000 or more. For example, if a company sells a parcel of garden for £100,000, the entire dwelling must be revalued from that date, and the new value could push the property into a higher ATED band even though part of the property has been sold.
There is no legal requirement for a professional formal valuation, but using a reputable surveyor is strongly recommended, particularly where the property value falls within 10% of an ATED threshold. In such cases, companies may apply to HMRC for a Pre-Return Banding Check (PRBC) before submitting their return, allowing HMRC to confirm the correct banding within approximately 30 working days.
ATED Reliefs: When No Tax Is Due
Several reliefs are available under ATED that can reduce the charge to nil. However, even where full relief applies and no tax is payable, a relief declaration return must still be submitted to HMRC by the filing deadline. Failure to file a relief declaration return on time still attracts penalties, even where no tax is due.
Relief is available where the dwelling is:
- Let to a third party on a commercial basis and is not, at any time, occupied by anyone connected with the owner
- Being developed for resale by a property developer
- Owned by a property trader as trading stock for the sole purpose of resale
- Held by a financial institution following repossession in the course of its lending business
- Open to the public for at least 28 days per year
- Occupied by qualifying employees or partners of a trading business as part of their employment
- A farmhouse occupied by a farm worker or former long-serving farm worker
- Owned by a registered provider of social housing or a qualifying housing co-operative
Charitable companies, public bodies, and bodies established for national purposes may be entirely exempt from ATED, meaning no return is required at all.
Filing Deadlines and Payment
ATED is a forward-looking tax, and the rules on timing are unusual compared to other UK taxes. Returns must be submitted, and any tax due paid, by 30 April at the start of the chargeable period. For example, the return and payment for the period 1 April 2026 to 31 March 2027 were both due by 30 April 2026.
Where a property is acquired during the chargeable period, the ATED return must be filed and tax paid within 30 days of the acquisition date. For newly constructed properties, the deadline is 90 days from the earlier of the property being first occupied or becoming a dwelling for Council Tax purposes.
All ATED returns must be filed online using HMRC’s ATED online service. Returns can be submitted directly or through an appointed tax agent.
Penalties for Late Filing and Non-Payment
ATED penalties can accumulate quickly, particularly where multiple properties are owned. The penalty structure for late filing is as follows:
- Day one after the filing deadline: £100 fixed penalty
- More than three months late: £10 per day for up to 90 days
- More than six months late: the higher of £300 or 5% of the estimated tax due
- More than twelve months late: a further penalty of the higher of £300 or 5% of the estimated tax due
For late payment of the ATED charge itself, a 5% surcharge applies on tax unpaid at the penalty date, with further 5% penalties applied at five months and eleven months after the penalty date.
The First-tier Tax Tribunal has confirmed that ignorance of the law does not constitute a reasonable excuse for missing filing deadlines, even for nil-liability returns.
Interaction with Stamp Duty Land Tax
ATED does not operate in isolation. Corporate bodies purchasing residential property worth more than £500,000 are also subject to the 15% flat rate of Stamp Duty Land Tax on the full purchase price, rather than the standard banding. Since 31 October 2024 this flat rate increased to 17%. Where a company holds a property that falls within ATED but has not paid the higher SDLT flat rate on acquisition, this may indicate an exposure that requires investigation.

Frequently Asked Questions
What is Annual Tax on Enveloped Dwellings?
ATED is an annual tax on UK residential properties worth more than £500,000 that are owned by companies, partnerships with a corporate member, or collective investment schemes. It was introduced in 2013 to deter corporate structures from being used as a vehicle to avoid Stamp Duty Land Tax on property sales.
When must I submit my ATED return?
Annual ATED returns must be filed and any tax paid by 30 April at the start of each chargeable period. For properties acquired during the year, the return must be filed within 30 days of acquisition. Newly built properties have a 90 day window from first occupation or Council Tax registration.
Do I still need to file if I qualify for a relief?
UK and non-UK companies, partnerships where at least one partner is a company, and collective investment vehicles such as unit trusts or OEIVs must pay ATED if they own a UK residential dwelling valued at more than £500,000.
How is the property valued for ATED purposes?
Properties are valued using a fixed five-year revaluation date. The current revaluation date is 1 April 2022, applying to chargeable periods 2023 to 2024 through to 2027 to 2028. Properties acquired after 1 April 2022 use their acquisition date. Substantial acquisitions or disposals of £40,000 or more trigger an earlier revaluation.
Can I challenge an ATED penalty?
Yes. If you disagree with an HMRC penalty or determination, you can appeal within 30 days of the decision to HMRC’s ATED Penalty Appeals team. Note that courts have rejected ignorance of the law as a reasonable excuse.
Does ATED affect how I pay tax when I sell the property?
ATED itself does not give rise to Capital Gains Tax. From 6 April 2019, disposals of ATED-subject properties by companies are taxed under standard Corporation Tax rules on any chargeable gain.
