Annual Tax on Enveloped Dwellings (ATED) 30 April deadline

The deadline for submission of ATED returns is 30 April 2026.

This applies if a single dwelling worth/costing more than £500,000 is held by a company or other non-natural person, such as a partnership with a corporate member. You must revalue your property every 5 years in line with ATED legislation.

If the property is being developed or let to unconnected parties, relief from the tax charge is available but a return needs to be submitted to claim it.

If this applies to your company and you would like us to deal with this on your behalf, please email your usual contact. We will already be aware of those who notified us last year so there is no requirement to notify us again.

Ongoing Requirement

Where a property is acquired during the year, an ATED return must be submitted within 30 days of acquisition, or for a newly built property within 90 days of the earliest of the date:

• the property becomes a dwelling for Council Tax purposes; or
• it is first occupied.
