ATED UK 2026 — Annual Tax on Enveloped Dwellings for Landlords

Who must file an ATED return?

ATED applies where all of the following conditions are met:

• Non-natural person: The property is owned by a company (UK or overseas), a collective investment scheme, or a partnership with a corporate member
• Residential property: The property is a dwelling — a building designed or adapted for use as a home. Commercial property, mixed-use property, and property used exclusively for non-residential purposes are outside the scope
• Value above the threshold: The property is worth more than £500,000 at the relevant valuation date. Properties below this value are outside the scope of ATED
• UK land: The property is situated in England, Scotland, or Wales (not Northern Ireland)
• The ATED return period runs from 1 April to 31 March each year. A return for the period 1 April 2026 to 31 March 2027 must be filed and payment made (or relief claimed) by 30 April 2026

ATED thresholds and annual charges 2026/27

The ATED annual charge depends on the property's value band. These are the 2026/27 rates (adjusted annually in line with CPI):

• £500,001 to £1 million: £4,450 per year
• £1 million to £2 million: £9,150 per year
• £2 million to £5 million: £30,550 per year
• £5 million to £10 million: £71,500 per year
• £10 million to £20 million: £143,550 per year
• Over £20 million: £287,500 per year
• These are annual charges — not one-off payments. A company owning a £1.5 million property for 5 years and failing to claim rental business relief would owe over £45,000 in ATED charges, plus interest and penalties

Property rental business relief — the main exemption

Most buy-to-let limited companies are entitled to the property rental business relief, which reduces the ATED charge to nil:

• Condition: The property must be let to unconnected third parties at arm's length. The tenants must not be connected to the company (e.g., the director's family members living rent-free or at below-market rent would not qualify)
• Annual return required: The relief is not automatic. The company must file an ATED return annually and tick the relief claim box. If no return is filed, HMRC treats the property as not qualifying for relief and issues an ATED charge
• Arm's length requirement: The tenancy must be on normal commercial terms. An AST at market rent to an unconnected tenant clearly qualifies. A tenancy to the company director, a director's relative, or a shareholder at below-market rent does not qualify
• Mixed use: If the director or a connected person uses any part of the property (including occasional use), the relief may be lost for the entire property for that period
• Void periods: Short void periods between tenancies do not disqualify the relief, provided the property is actively marketed for letting throughout the void period

Other ATED reliefs available

Beyond the property rental business relief, other reliefs may apply:

• Property developers relief: Available where the company acquires the property for the purpose of developing and selling it. Does not apply to buy-to-let portfolios
• Property traders relief: Available where the company is in the business of buying and selling residential property (not letting). Rare in the landlord context
• Financial institutions relief: For banks and financial institutions that acquire residential property in the course of their lending business
• Regulated collective investment schemes: Available to REITs and similar structures
• Farmhouses and agricultural property: Where the property is occupied by a farm employee and used for agricultural purposes
• Most buy-to-let limited companies will rely solely on the property rental business relief. Where a company director also occupies part of the property, specialist ATED tax advice is essential

ATED filing obligations and penalties

The filing and payment requirements are strict with automatic penalties:

• Filing deadline: The ATED return for each chargeable period (1 April to 31 March) must be filed by 30 April at the start of the period. For 2026/27, the deadline is 30 April 2026
• First-year returns: Where a company acquires a property during the year, a return must be filed within 30 days of the date on which it first became an ATED property
• Automatic penalties: Failure to file by the deadline: £100 automatic penalty. 3 months late: a further £10/day penalty up to 90 days. 6 months late: the greater of 5% of the ATED charge or £300. 12 months late: a further penalty
• Relief claim returns: Even where the company claims the property rental business relief and the ATED charge is nil, a return must still be filed by the deadline to record the relief claim. Failure to file attracts the same automatic penalties
• Interest on late payment: HMRC charges interest on late payment of the ATED charge from the payment deadline. The rate is set at the Bank of England base rate plus 2.5%

ATED and SDLT — the 15% flat rate

ATED interacts with SDLT in a significant way for high-value corporate acquisitions:

• 15% SDLT flat rate: Where a non-natural person acquires a residential property worth more than £500,000, a flat 15% SDLT rate applies (in addition to any ATED charge). This is designed to discourage enveloping high-value properties in companies purely for tax avoidance
• Relief from the 15% rate: The same reliefs that apply to ATED (including property rental business relief) also relieve the 15% SDLT flat rate — but the relief must be claimed on the SDLT return and the conditions must be met
• Planning point: For buy-to-let limited companies, the 15% SDLT rate and annual ATED filing obligations mean that corporate ownership of properties above £500,000 in value requires careful tax planning. The Section 24 savings from corporate ownership must be weighed against these additional costs and compliance burdens
• Specialist landlord tax advice from a chartered accountant or tax specialist is strongly recommended before acquiring high-value property in a limited company structure
