A Complete Guide to Annual Tax on Enveloped Dwellings (ATED)

ATED (Annual Tax on Enveloped Dwellings) is an annual tax payable by a company that owns UK residential property valued at more than £500,000. This limit is applicable per property.

Annual Tax on Enveloped Dwellings (ATED) is a tax charged in the UK to corporate bodies holding ‘single dwelling interests’ in the UK. 

Motive Behind Introduction of ATED

With the intention of combating a series of anti-avoidance schemes and making it less attractive to hold high-value UK residential property via a corporate structure, ATED regime was introduced by Finance Act 2013, Part 3.

The main reasons behind introducing the ATED are:

• Transparency - ATED promotes transparency by requiring companies to declare ownership of high-value residential properties, preventing tax avoidance.
• Fairness - It aims to ensure that individuals and companies owning high-value residential property make a fair contribution to the tax system.
• Revenue generation - ATED generates additional tax revenue, which can be utilised for public welfare and infrastructure development.

Applicability of ATED

The ATED regime applies to UK residential property owned by ‘non-natural persons’, including:

• Companies
• Partnerships with at least one company member, or
• Collective investment schemes

Property Ownership

In the UK, property ownership plays a key role in determining how ATED applies. Residential properties can be owned either as freehold or leasehold, and the ownership structure can influence tax obligations under ATED. Understanding these ownership types is essential for companies to assess their tax liabilities correctly.

Freehold Estate

A freehold estate represents full ownership of a property and the land it stands on. If a company owns a freehold interest in a UK residential property, it may be subject to ATED. The company must determine its compliance obligations, submit an ATED return, and pay any applicable tax unless a relief or exemption applies.

Leasehold Estate

A leasehold estate grants the right to use and occupy a property for a fixed period under a lease agreement. If a company holds a leasehold interest in a UK residential property, it may also be subject to ATED, particularly if the lease is long-term. The company must assess whether it falls under ATED rules, file the required ATED return, and claim any eligible reliefs if applicable.

Meaning of Dwelling for ATED

As previously mentioned, ATED applies specifically to "single-dwelling interests." Determining whether a property qualifies as a single dwelling interest begins with establishing whether it meets the criteria to be considered a dwelling. For ATED purposes, a dwelling typically consists of residential units, such as houses or flats, which are used as individual residences. Non-residential buildings are generally not subject to ATED.

HMRC’s guidance expands the definition of a dwelling to include not only the main building but also land which comprises the grounds or gardens to a dwelling and any other land that is, or is at any time, intended to be occupied or enjoyed with a dwelling. Some of the examples stated in the HMRC’s guidance include: a garden, a tennis court, drive, garage, swimming pool and changing room, summerhouses etc.

It is crucial to note that where a building is capable of being used as a separate dwelling, such building would not be prevented from forming a part of a larger single dwelling. For example, where there is a ‘flat’ above the garage or a separate ‘flat’ inside the house, these may be included as part of the main dwelling. However, this may change depending on the facts of each case.

However, dwellings excludes the followings:  

• Hotels
• Guesthouse
• Boarding School Accommodation
• Hospitals
• Student Halls of Residence
• Military Accommodation
• Care Homes
• Prisons

Valuation for ATED

Non-natural persons holding UK residential properties must be informed of the valuation requirements for ATED purposes. Typically, the property's value, subject to ATED, is determined by its market value on the valuation date. Revaluation dates occur every five years from 1 April 2012, with each revaluation date applying to five consecutive chargeable periods.

For the current five-year cycle, the relevant valuation date is 1 April 2022. Properties owned on or before this date must be valued as at 1 April 2022, while properties acquired after this date should use the date of acquisition as the valuation date. The next revaluation date will be 1 April 2027.

Although it is not mandatory for companies to use a professional surveyor or estate agent to revalue the property, it is advisable to do so as it ensures the robustness and reasonableness of the figures. Additionally, valuations must be a precise amount and not ‘falling within ATED range’ type valuations.

Where there remains uncertainty about which ATED band a property falls into particularly where the valuation is close to a band threshold. Companies can apply to HMRC for a pre-return banding check before submitting their return. This provides greater certainty and helps avoid the risk of filing in the wrong band.

Sample Letter from HMRC - Disagreement Over Property Valuation

Although the property doesn't need to be professionally valued, HMRC may sometimes disagree with the valuation provided. If they disagree, you will receive a letter as follows:

Substantial Acquisitions and Disposals on Dwellings

In addition to the 5-year valuation rule, the substantial acquisition and disposal of the chargeable dwelling by the companies trigger the need for revaluation for ATED purposes.

Generally, an acquisition of a chargeable interest in a dwelling is a ‘substantial acquisition’ if the chargeable consideration for the acquisition (including any linked acquisition of a chargeable interest in or over the same dwelling) is £40,000 or more.

When to File the ATED Return?

If the company is within the scope of ATED on 1 April, it is required to submit the annual ATED return.

The ATED return is prepared to 31 March annually irrespective of the company's year-end, and unlike other tax returns, ATED is forward-looking.

E.g., The return for year ending 31 March 2027 will have to be submitted to HMRC by 30 April 2026. 

You usually need to submit the return for:

How to Register for ATED?

Before submitting an ATED return, companies must register for the ATED online service. Both the company and any appointed agent must register separately using their own sign-in details. Where a company has more than one business with enveloped properties, separate sign-in details must be created for each business.

To register, the company will need its registered business name and Unique Taxpayer Reference (UTR). The UTR is made up of 10 or 13 digits. If 13 digits, only the last 10 should be entered. For a chargeable return, the property's address, market value and title number will also be required.

Registering as a Business

A business registers for the ATED online service to submit its own returns or to appoint an agent to submit returns on its behalf. To appoint an agent, the agent must already be registered and must provide the company with a unique authorisation number to enter during registration.

Registering as an Agent

Agents register using their agency's business name and UTR, then add clients to their account. A unique authorisation number is generated per client and shared with them to complete the appointment. Where multiple staff handle ATED matters, additional administrators can be added to the agency account.

Overseas Businesses Without a UTR

Overseas companies without a HMRC UTR can register for the online service directly or appoint an agent to do so on their behalf. Those wishing to appoint an agent should complete an ATED1 form, which allows the agent to complete registration on their behalf.

To register, sign in to the ATED online service using existing Government Gateway credentials or create new sign-in details if not already registered. Once registration is complete, the online service can be used to submit returns, appoint agents, save and retrieve drafts, amend previously submitted returns, and obtain a payment reference number upon submission.

How to Submit an ATED Return?

All ATED returns are submitted online through the ATED online service. There are two types of return depending on the circumstances: 

• Where an ATED charge is due, a chargeable return must be submitted for each property. HMRC calculates the amount owed based on the information reported, and an instant payment reference number is issued upon submission. The online service saves the return as a draft for 60 days, allowing completion in stages.
• Where a relief applies, a Relief Declaration Return must be submitted instead. (see Reliefs Available Under ATED below)

How to Pay Your ATED Charge?

The payment deadline mirrors the filing deadline. Ordinarily 30 April at the start of the chargeable period, or the same later date where a later filing deadline applies, such as for new acquisitions or newly built properties.

A payment reference number issued upon submission of return must be used when making payment to ensure correct allocation by HMRC. If the deadline falls on a weekend or bank holiday, payment must reach HMRC by the end of the previous working day.

What are the ATED Annual Charges?

The amount payable under ATED is determined by a banding system based on the market value of the property. Charges are reviewed annually and have increased each year. The table below shows the current and two preceding chargeable periods for comparison. For historic rates prior to 2024–2025, refer to HMRC's guidance.

Reliefs & Exemptions Available Under ATED

There are number of ATED reliefs which may eliminate or reduce the amount payable for ATED.

Generally, the relief can be claimed if the property under the question is:

• Let to a third party on a commercial basis and is not, at any time, occupied (or available for occupation) by anyone connected with the owner
• Open to the public for at least 28 days a year
• Being developed for resale by a property developer
• Owned by a property trader as the stock of the business for the sole purpose of resale
• Repossessed by a financial institution as a result of its business of lending money
• Acquired under a regulated home reversion plan
• Being used by a trading business to provide living accommodation to certain qualifying employees
• A farmhouse occupied by a farm worker or a former long-serving farm worker
• Owned by a registered provider of social housing or a qualifying housing co-operative

How to Claim Reliefs

Reliefs are claimed through the ATED online service by submitting a Relief Declaration Return. This is still required even where the relief reduces the ATED charge to nil. Failure to do so may result in penalties even where no tax is ultimately due.

A single Relief Declaration Return can cover multiple properties eligible for the same relief, but where different reliefs apply, a separate return must be submitted for each relief type.

ATED Relief: Homes for Ukraine Sponsorship Scheme

From 1 April 2022, specific ATED reliefs were preserved for properties made available to house individuals arriving in the UK under the Homes for Ukraine Sponsorship Scheme. This provision also extends to individuals who subsequently transfer to the Ukraine Permission Extension Scheme.

The reliefs for property rental relief, property developers relief and property traders relief continue to be available. This means that where a company's property would ordinarily qualify for one of these reliefs but is occupied by individuals under the Homes for Ukraine or Ukraine Permission Extension Scheme, the relief is not lost solely by virtue of that occupation.

ATED Exemptions

In addition to the reliefs described above, certain entities are entirely exempt from ATED. Where an exemption applies, no ATED return is required at all.

The following are exempt from ATED:

• Charitable companies holding a property for qualifying charitable purposes, provided the relevant conditions are met. Note that a subsidiary company owned by a charitable company does not itself qualify for this exemption, though it may still be eligible to claim ATED reliefs
• Public bodies, including central and local government authorities, NHS bodies, and devolved administration bodies across England, Wales, Scotland and Northern Ireland
• Bodies established for national purposes, including the Historic Buildings and Monuments Commission for England, the Trustees of the British Museum, the Trustees of the National Heritage Memorial Fund, and the Trustees of the Natural History Museum
• Dwellings conditionally exempt from Inheritance Tax, where the property has been designated as of national interest and the owner has committed to preserve it and allow reasonable public access, in which case the dwelling is treated as having a taxable value of zero for ATED purposes

The conditions attaching to each exemption, particularly for charitable companies, can be complex. We therefore advise seeking professional advice to confirm whether an exemption applies before concluding that no filing obligation exists.

Fines & Penalties for Non Filing 

Failure to file tax returns or other necessary documents on time may result in the imposition of the following penalties:

• An initial penalty of £100 will be applied the day after the due date of your tax return or document.
• Daily penalties of £10 per day will be incurred for up to 90 days following a three-month delay in filing your return or document.
• A 'further penalty' of £300 or 5% of our estimate of your tax liability (whichever is higher) will be levied after a six-month delay in filing your tax return or document.
• A second 'further penalty' of £300 or 5% of our estimate of your tax liability (whichever is higher) will be imposed after a twelve-month delay in filing your tax return or document.

In instances where tax returns or documents have not been filed, HMRC reserves the right to estimate the tax liability. In such cases, the penalties charged at the six-month and twelve-month marks will be 5% of the estimated liability or £300, whichever amount is higher.

Upon filing your return or document, the penalties at the six-month and twelve-month marks will be automatically recalculated if the tax liability in the return differs from our initial estimate.

After HMRC has applied the second further penalty, the percentage rate will escalate if, by failing to submit your return or document within twelve months, you:

• Concealed information.
• Were aware that the information could aid in determining your precise tax liability.

During the assessment, HMRC will ascertain whether there is a withheld of information and, if so, the underlying rationale. This rationale is referred to as the 'behaviour'. HMRC charges different penalties based on the behaviour it deems fit.

Sample Letter from HMRC- Late Filing Penalty Notice

You might receive a letter as shown below if you either fail to file the ATED return on time, or fail to pay the ATED charges on time.

Sample Letter from HMRC- Disclosure for Annual Tax on Enveloped Dewllings

You might receive a letter such as shown below to disclose the annual tax on enveloped dwellings/Non resident landlord liabilities from HMRC.

Fines & Penalties for Non-Payment of Annual Charge

Penalties under ATED follow the rules that apply to the income tax and corporation tax self-assessment regimes and cover late filing, late payment and inaccuracies.

When ATED is not paid on time, whether partly or in full, the penalties charged is as follows:

• An initial penalty of 5% of the tax unpaid at the penalty date and
• Two further penalties of 5% of the tax unpaid at 5 and 11 months after the penalty date

For more detailed information, explore HMRC’s guidance.

Fines & Penalties for Inaccurate Returns

The penalty percentage is classified into one of six ranges, determined by the nature of the behaviour and whether the disclosure was 'prompted' or 'unprompted'. The table below outlines these six penalty ranges.

Amendment of ATED Return

ATED return needs to be amended if

• You have disposed of the property
• Error in the information sent earlier
• Claiming a relief

The amended return must be submitted within 12 months of the end of the relevant period. If you submitted your original return after 1 January following the end of the relevant chargeable period, you would need to make any changes within 3 months of the date you submitted your original return.

Conclusion

In summary, ATED imposes an annual tax on UK residential properties owned by companies valued above £500,000. It aims to counter avoidance schemes, promote fairness, and generate revenue for public welfare. Compliance with ATED, including valuation, filing, and relief requirements, is crucial to avoid fines. Given the complexity, seeking professional advice is advised for accurate reporting and compliance.
