The Annual Tax on Enveloped Dwellings (ATED) is one of those compliance obligations that can catch property owners off guard.
It might just be that you did not know the tax applied to you or the filing deadline crept up on you before you could act.
The deadline for filing your return might have passed, but that does not mean your obligations have disappeared and you need to know how to remain compliant.
What is ATED?
The ATED is an annual tax charge on UK residential property valued at more than £500,000.
It specifically targets properties held in a corporate envelope and not those owned directly by individuals.
A common misunderstanding we see is that ATED only applies where tax is payable. Many entities are actually still required to submit a return even if their eventual liability is nil.
How much ATED do I pay?
The amount of ATED you pay is determined by the market value of the property at a specific valuation date.
The ATED operates on a five-year revaluation cycle and we are currently within the period based on the 1 April 2022 valuation.
Any property acquired after 1 April 2022 will be assessed based on its valuation on the date of purchase.
Your property’s valuation is self-assessed and this does place a lot of pressure on the taxpayer to get it right. An incorrect or unsupported valuation can lead to HMRC enquiries and penalties.
How is ATED calculated?
You will need to use a banding system based on your property’s value to calculate your ATED.
For the 2026/27 period, the annual charges are:
| Property value | Annual charge |
| £500,000 – £1 million | £4,600 |
| £1 million – £2 million | £9,450 |
| £2 million – £5 million | £32,200 |
| £5 million – £10 million | £75,450 |
| £10 million – £20 million | £151,450 |
| Over £20 million | £303,450 |
You can see just how much of a jump it is when you cross into a higher band, so accurate valuation is crucial.
Even a small error could place your property in the wrong band and trigger unnecessary costs or scrutiny.
When do you need to file?
The ATED returns must be submitted at the start of each chargeable year.
The filing deadline for this 2026/27 tax year was 30 April 2026.
You need to get moving if you realised that ATED applies to your property and you’ve missed the filing deadline.
An initial £100 penalty is applied for late filing and this is followed by daily penalties of £10 after three months (reaching up to £900).
There can also be further penalties of £300 or 5 per cent of the tax due, whichever is higher, that can apply at the six and twelve month marks.
There is also the risk of interest to the tax or HMRC enquiries into late or inaccurate returns.
It is also important to note that a property that has been newly acquired and falls within the ATED requirements must have a return submitted within 30 days of acquisition.
Newly constructed properties often have a deadline of 90 days to file from the date the property becomes a dwelling.
What are dwellings for ATED?
A dwelling, in regard to ATED, is any property that is used or could be used as a residence. This could include houses, flats, maisonettes and land associated with the property, such as gardens or outbuildings.
A property does not need to be actively occupied to qualify for ATED, as long as it is capable of residential use.
Although certain types of property fall outside the definition, such as:
- Hotels
- Guest houses
- Hospitals
- Student halls of residence
- Care homes
- Military accommodation
- Prisons
Properties with mixed commercial and residential elements will need a more detailed assessment to determine whether ATED applies.
