ATED

Annual Tax on Enveloped Dwellings (ATED) is an annual tax charge payable by companies, or partnerships with at least one corporate partner, and certain collective investment schemes that hold UK residential properties valued at more than £500,000.

Each ATED chargeable period runs from 1 April to 31 March. A return must be filed online with HMRC, and any tax due must be paid within one month of the start of the chargeable period to avoid penalties and interest.

Valuation Requirements

ATED is calculated based on the taxable value of the property. Properties must be revalued for ATED purposes every five years. The most recent valuation date was 1 April 2022, and this value — or the acquisition cost if the property was purchased after that date — determines whether the property falls within the ATED regime for the 2025/26 chargeable period.

Reliefs Available

A number of ATED reliefs may apply, including reliefs for:

• Property rental businesses
• Property developers
• Farmhouses occupied by qualifying agricultural workers

Eligibility must be checked carefully, as occupation by a non‑qualifying individual can invalidate the relief. Where a relief applies, it must be claimed via a Relief Declaration Return, which must be submitted to HMRC by 30 April 2026 for the 2026/27 period.

Properties Acquired, Constructed or Converted During the ATED Year

Acquisitions

If a UK residential property worth more than £500,000 is acquired through a corporate wrapper during the ATED period, an ATED return — and payment — is due within 30 days of completion.

No return is required if the property is fully covered by a relief that has already been declared for that chargeable period.

Developments or Conversions

If a property is developed or converted so that it becomes a dwelling valued above £500,000 during the ATED year, an ATED return and payment are required within 90 days of the earlier of:

• The date the property becomes liable for Council Tax; or
• The first date of occupation (typically completion).

Again, no return is required if an appropriate relief has already been declared for the chargeable period.

Managing Your ATED Compliance

Your ATED liability is confirmed through the submission of an ATED return.

ATED is a complex regime. Ensuring that the right amount of tax is paid at the right time — using the correct forms and relief claims — is essential to minimise risk and prevent unnecessary interest or penalties.
