This article is the latest in a series of short summaries contributed by Duncan Reoch, Private Tax Partner at EY Scotland, and his team, to provide insight into lesser-known tax provisions for residential property owners.

Annual Tax on Enveloped Dwellings (ATED)

Although it has existed since April 2013, ATED is a relatively unknown property related tax. We see this typically applying in client situations where a company owns expensive residential properties which are occupied or available for use by the shareholders or their relatives.

The tax was introduced to dissuade companies from purchasing expensive residential properties as purely speculative assets, rather than as buy-to-lets or as part of a property development trade.

Companies that own a “chargeable interest” in a residential dwelling (e.g. freehold, commonhold, leasehold, etc.) worth more than £500,000 are subject to the ATED regime. The amount due depends on:

1. The value of the dwelling

2. Whether the dwelling has been owned for the full chargeable period (which runs from 1 April to 31 March) or only part of the chargeable period

3. Whether they are entitled to full or partial tax relief

The amount of ATED due each year is given below. The amounts are pro-rated if the dwelling was not owned for the full chargeable period or if relief is available.

Taxable value of the interest on the relevant day

Annual chargeable amount for chargeable period beginning 1 April 2025

Over £500,000 up to £1 million

£4,450

Over £1 million up to £2 million

£9,150

Over £2 million up to £5 million

£31,050

Over £5 million up to £10 million

£72,700

Over £10 million up to £20 million

£145,950

Over £20 million

£292,350

What matters most is the value ofthe property itself. A company that owns just 1% of a property worth £2.5m would owe the full £31,050, despite its share of the property only being worth £25,000. There are also valuation conditions which require affected properties to be valued every 5 years from April 2012 (April 2027 is the next valuation date).

As long as the dwelling is used for business purposes (e.g. a property rental business), full relief is usually available. Nonetheless, nil returns must still be filed with HMRC each year. The standard filing deadline is 30 days following the beginning of the chargeable period (i.e. by 30 April each year) or within 30 days of acquiring an interest in a dwelling. Penalties are due for late filings and interest is applied to late paid liabilities.

Although the overarching principles of ATED are relatively straightforward, in practice, there are plenty of pitfalls for the unwary, as illustrated in the examples below.

  • Example 1: Overlooking Filing RequirementsChevron-down

    Acme Corporation Ltd is a property rental business that owns various high-value residential flats. The directors mistakenly assumed that, because relief is available in full, ATED returns are not required. HMRC opens an enquiry. Despite no tax being due, significant late filing penalties are levied on the basis multiple returns were required spanning several years.

  • Example 2: Revaluation Related PitfallsChevron-down

    In 2023, a dwelling worth £1.95m was partially acquired by a family investment company (FIC) and partially by several family trusts. The FIC is subject to the ATED charge and has budgeted £9,150 per year to pay the tax. The next revaluation is due 1 April 2027.

    A year later, the FIC buys out the trusts' interests in the property for £250,000. Since the consideration was at least £40,000, the property needs to be revalued. The valuer concludes the property is now worth just over £2m. Consequently, the annual chargeable amount increases from £9,150 per year to £31,050 per year.

  • Example 3: ATED Relief Can Be ComplexChevron-down

    Bravo Ltd is a property rental business that owns a property worth £1.25m in Glasgow, acquired on 1 April 2024. An ATED return is, therefore, due by 30 April 2024 in which full relief can be claimed.

    When, exactly one year later, the tenant hands in their notice, the controlling shareholder’s daughter offers to rent the property short-term, until a new tenant can be found. She agrees to pay full market value rent during her stay.

    Unbeknownst to the directors, relief is not available when a tenant is “connected” with the company owner. As such, in the ATED return due 30 April 2025, £9,150 will be payable. If, later in the year, the shareholder’s daughter is replaced with a new tenant, an amended return could be filed to claim a partial refund.

    Note, for the purposes of the ATED legislation controlling shareholders are “non-qualifying” individuals (i.e. relief is not available for days during which they occupy the property) and so is anyone “connected” with them. Connected individuals include, but are not limited to, siblings, parents, grandparents, children, grandchildren and spouses.

Due to the complexity of the ATED regime, the above is necessarily a high-level summary only. As always, independent tax advice should be sought were relevant.

While this article has focused on companies, it is worth pointing out that ATED applies to other entities as well, including partnership with a corporate partner, and collective investment schemes like unit trusts. Separate connection rules exist for these structures.
