Annual Tax on Enveloped Dwellings (ATED) - What You Need to Know Before 30 April 2026

If your company owns UK residential property valued above £500,000, you may fall within the scope of the Annual Tax on Enveloped Dwellings (ATED). With the 30 April 2026 filing deadline approaching, now is the time to check whether you need to submit an ATED return or relief declaration.

An ATED return must be completed if your property meets the following criteria:

• It constitutes a dwelling (such as a house or flat), including any associated gardens, grounds, or buildings. 
• It is located within the UK. 
• It is owned either wholly or partly by a company, a partnership with corporate partners, or a collective investment scheme. 
• Its value exceeds £500,000. 

The term 'dwellings' excludes hotels, guest houses, boarding school accommodation, hospitals, student halls of residence, military quarters, care homes, or prisons.

However, relief from this tax is available under the following circumstances:

• The property is used in a property rental, property development, or property trader business. 
• The property is made accessible to the public. 
• The owning company is a financial institution acquiring property for lending purposes. 
• The property provides accommodation for employees. 
• The property is used for social housing or is a farmhouse (except if certain connected persons reside there). 

If your property falls under the ATED regulations, an ATED return must be filed:

• By 30 April 2026, if on 1 April, the property was within the scope of ATED. 
• Within 30 days of acquisition if the property falls within the scope ATED after 1 April. 
• For newly constructed properties, within 90 days of either the date it becomes a dwelling for Council Tax purposes or the date of its first occupation. 

Non-compliance may result in penalties and interest. 

Furthermore, where relief is available, a relief declaration return must be submitted by the same deadlines.
