ATED: Annual Tax on Enveloped Dwellings Explained

What Is ATED?

The Annual Tax on Enveloped Dwellings — universally known as ATED — is an annual tax that applies to UK residential properties valued at more than £500,000 when they are owned (or "enveloped") by a company, a partnership with a corporate member, or a collective investment scheme.

ATED was introduced in 2013 as part of a package of measures designed to discourage the practice of holding high-value residential property in corporate structures to avoid Stamp Duty Land Tax and Capital Gains Tax. Whether or not that was your reason for using a company, if the property falls within the rules, ATED applies — unless you qualify for a relief.

This guide explains the ATED rules for the 2025/26 charging period, including the rates, reliefs, and filing requirements.

When Does ATED Apply?

ATED applies when all of the following conditions are met:

1. The property is a dwelling. A dwelling means a building used or suitable for use as a single dwelling, or a building that is being adapted or developed for such use. This includes houses, flats, and apartments. It does not include hotels, guest houses, boarding school accommodation, hospitals, student halls of residence, military accommodation, or care homes.

2. The property is in the UK. The property must be located in England, Scotland, Wales, or Northern Ireland.

3. The property is valued at more than £500,000. The value is based on the most recent ATED valuation date (see below).

4. The property is owned by a "non-natural person." This means a company (UK or non-UK), a partnership with at least one corporate partner, or a collective investment scheme. Individual ownership and ownership by trusts (where the trustees are individuals) is outside the scope of ATED.

If all four conditions are met on 1 April of the charging year, ATED is due for that year.

ATED Valuation Dates

ATED valuations are required at five-year intervals. The relevant valuation dates are:

• 1 April 2012 (the original valuation date)
• 1 April 2017
• 1 April 2022
• 1 April 2027 (the next revaluation)

For the 2025/26 charging period, the relevant valuation is the value as at 1 April 2022, or the acquisition price if the property was purchased after that date.

If you acquired the property for £480,000 but it was worth £550,000 on 1 April 2022, ATED applies. Conversely, if you paid £600,000 but the 1 April 2022 value was below £500,000, ATED does not apply for 2025/26.

You should obtain a professional valuation (from a RICS-qualified surveyor) for each valuation date. HMRC can challenge valuations, and a professional report provides the strongest defence.

ATED Rates for 2025/26

ATED is charged at fixed annual amounts based on the property's value band. The rates for the 2025/26 charging period are:

| Property value (at valuation date) | Annual ATED charge | |---|---| | More than £500,000 but not more than £1 million | £4,400 | | More than £1 million but not more than £2 million | £9,000 | | More than £2 million but not more than £5 million | £30,550 | | More than £5 million but not more than £10 million | £71,500 | | More than £10 million but not more than £20 million | £143,550 | | More than £20 million | £287,500 |

These rates are adjusted annually in line with the Consumer Prices Index (CPI). The amounts shown are approximate and should be confirmed with the latest HMRC guidance for the relevant charging period.

For properties in the lowest band (£500,001 to £1 million), the annual charge of £4,400 may seem modest. For properties over £20 million, the charge of £287,500 is substantial and provides a strong incentive to consider whether the corporate structure is still appropriate.

ATED Reliefs

ATED would catch many legitimate property arrangements if it were not for the reliefs. Several important reliefs exist, and if you qualify, the ATED charge is reduced to zero — although you must still file a return to claim the relief.

Property rental relief

If the property is let to a third party on a commercial basis and is not occupied (or available for occupation) by anyone connected with the owner, the letting relief applies. This is the most commonly claimed relief and covers buy-to-let properties held in companies.

"Connected persons" includes directors, shareholders, their family members, and anyone associated with them. If any connected person occupies the property — even briefly — the relief may be lost for that period.

Property development relief

If the property is being held by a property developer for the purpose of developing and reselling it, property development relief applies. The company must be carrying on a property development trade, and the property must be acquired exclusively for development with a view to disposal.

If you buy a property, develop it, and then decide to keep it as a rental, the development relief ceases from the point you change your intention.

Property trading relief

If the property is held as trading stock by a property trading company, the trading relief applies. The property must be acquired with the sole purpose of resale at a profit as part of the company's trade.

Charitable use relief

Properties held by a charity for charitable purposes qualify for relief.

Public body relief

Properties owned by public bodies and used for public purposes qualify for relief.

Farmhouse relief

A farmhouse occupied by a qualifying farm worker in connection with farming activities qualifies for relief, provided the farmland is commercially farmed.

Social housing relief

Properties used for social housing qualify for relief.

Financial institution relief

Properties acquired by financial institutions in the course of lending (for example, when a bank repossesses a property) qualify for a temporary relief.

Filing Requirements

Who must file

Every company (or other non-natural person) that owns a UK residential property valued at more than £500,000 on 1 April of the charging year must file an ATED return — even if a relief applies and no tax is due.

Filing deadlines

• Existing properties: The return for the charging period (1 April to 31 March) must be filed by 30 April of the charging year. For 2025/26, the return is due by 30 April 2025.
• Newly acquired properties: If you acquire a property during the charging period, the return is due within 30 days of acquisition.
• Properties that come into charge mid-year: If a relief ceases to apply during the year (for example, you stop letting the property commercially), you must file a return within 30 days.

Payment deadlines

ATED payments are due on the same date as the filing deadline. For 2025/26, payment is due by 30 April 2025.

Penalties

Late filing attracts an initial penalty of £100, with further penalties of £10 per day if the return is more than three months late (up to 90 days). After six months, there is a further penalty of 5% of the tax due (or £300, whichever is greater). After 12 months, another 5% or £300 penalty applies.

Late payment attracts interest from the due date, plus surcharges of 5% at 30 days, a further 5% at six months, and a further 5% at 12 months.

ATED and Related Taxes

ATED does not exist in isolation. It is part of a broader framework designed to discourage corporate ownership of residential property:

ATED-related CGT

When a company sells a property that has been within the ATED regime, any gain may be subject to ATED-related Capital Gains Tax at 28%. This applies in addition to any Corporation Tax on the gain. However, if a relief from ATED applied throughout the period of ownership (for example, the property was always let commercially), ATED-related CGT does not apply, and the gain is subject to Corporation Tax in the normal way.

Stamp Duty Land Tax

Companies purchasing residential properties over £500,000 pay a higher rate of SDLT — 15% on the entire purchase price (not just the excess over £500,000). Reliefs broadly mirror the ATED reliefs: if the property is acquired for letting, development, or trading purposes, the 15% rate does not apply, and the standard (or higher rate) SDLT rates apply instead.

Interaction with Corporation Tax

The ATED charge itself is not deductible for Corporation Tax purposes. It is a separate tax that must be paid in addition to any Corporation Tax due on rental profits or capital gains.

Should You De-Envelope?

Given the cost of ATED, SDLT, and ATED-related CGT, many property owners have removed their properties from corporate structures — a process known as de-enveloping. This involves the company transferring the property to the individual shareholders, which triggers SDLT (on the market value) and potentially CGT for the company.

Whether de-enveloping makes financial sense depends on:

• The ATED charge (which is ongoing)
• The SDLT cost of de-enveloping (a one-off cost)
• The CGT position on de-enveloping
• Future plans for the property (sale, letting, personal use)
• Income Tax implications of rental income received personally versus through a company
• Inheritance Tax planning considerations

This is a complex decision that should be made with professional advice.
