Annual Tax on Enveloped Dwellings (ATED): Who Pays It and How to Comply

What Is ATED?

The Annual Tax on Enveloped Dwellings (ATED) is a UK tax levied on residential properties with a value above a certain threshold that are owned by "non-natural persons" — primarily companies, but also partnerships with at least one corporate partner and certain collective investment schemes.

ATED was introduced by the Finance Act 2013 as part of a package of measures designed to discourage the use of corporate wrappers (often called "envelopes") to hold high-value residential properties for tax avoidance purposes, in particular to avoid Stamp Duty Land Tax on property transfers and inheritance tax on death.

Who Is Subject to ATED?

ATED applies to a "non-natural person" that:

• Owns a chargeable interest in a single-dwelling interest (i.e. a residential property or part of one), and
• The property's taxable value is above the ATED threshold.

The ATED threshold (the minimum property value that triggers liability) has been £500,000 since 1 April 2016. Properties valued below £500,000 fall outside ATED entirely.

The charge applies to a wide range of "non-natural persons" including:

• UK companies and non-UK companies
• Collective investment schemes (including open-ended investment companies)
• Partnerships where any partner is a company

It does not apply to individual homeowners, bare trusts, or partnerships where all partners are natural persons (individuals).

ATED Charges for 2025/26

ATED charges are banded by property value and are uprated annually by the Consumer Prices Index. For the 2025/26 chargeable period (1 April 2025 to 31 March 2026), the annual charges are:

These figures are approximate. Consult HMRC's current guidance for the exact amounts applicable in any given chargeable period.

ATED Reliefs — Reducing the Charge to Zero

The majority of corporate-held residential properties are not subject to an ATED charge in practice because they qualify for one of the statutory reliefs. The most common reliefs are:

**Property rental business relief:** Available where the property is being commercially let to a third party at arm's length and is not occupied by any person connected to the corporate owner. This relief covers most genuine buy-to-let investments held by companies.

**Property developer relief:** Available where the property is held as stock for the purpose of a qualifying property trading business (i.e. the company buys, develops and sells property as its business activity).

**Property trading business relief (for companies that trade in dwellings):** Available to companies that carry on a property trading business — buying and selling residential property as a trade.

**Farmhouse relief:** Available for a farmhouse occupied by a working farmer.

**Charitable relief:** Available where the property is held by a charitable company.

Reliefs must be claimed by filing an ATED Relief Declaration Return with HMRC for each chargeable period, even where no charge is payable. Failure to file is itself a compliance failure.

Filing Deadlines

The ATED return (or relief declaration return) for each chargeable period must be filed and any tax paid by:

• **30 April** in the chargeable period (i.e. 30 April 2025 for the 2025/26 period).
• Where a company first acquires a residential property or it first exceeds the threshold during the chargeable period, the first return is due within 30 days of the acquisition or valuation date.

ATED returns are filed online via HMRC's ATED online service.

Penalties for Non-Compliance

HMRC can charge:

• Late filing penalties (starting at £100 for returns filed up to three months late, escalating to 5–10% of the ATED charge for longer delays).
• Interest on unpaid ATED charges.
• Penalties for inaccurate returns where the inaccuracy is careless or deliberate.

Given that the property valuation used for banding purposes is based on the property's open market value (using HMRC's valuation date rules), companies should obtain professional valuations at the relevant dates and retain them in case of HMRC enquiry.
