Most directors of UK property companies have heard of ATED, and most have a vague sense that it is "the annual tax on company-held London houses". That description is right in spirit and wrong in nearly every detail that matters for a 2026/27 strategic decision. ATED catches a narrower population than most expect (a single residential dwelling worth more than £500,000, held by a non-natural person), it interlocks with the 15% flat-rate SDLT at acquisition and Schedule A1 IHTA 1984 at death in ways that decide corporate posture for years, and it is moving through three pressures in 2026/27 that make this the natural year for boards to take a fresh look.

This page is the strategic overview, not the operational walkthrough. The 2026/27 pillar guide carries the mechanics: every band, every relief, the full return procedure, the valuation rules, and the penalty cascade. Here, the focus is one level up: the cohort map of who is actually in scope, the three-tax interlock, what has moved between 2025/26 and 2026/27, and the strategic posture choices a board has when the property sits inside a corporate envelope.

Why the 2026/27 ATED Position Is Worth Reviewing Now

Three pressures push 2026/27 into the strategic-review window for any corporate holder of a £500,000-plus UK dwelling, and they compound rather than substitute for each other.

The first is the five-yearly revaluation. ATED bands are tested against the open-market value at the most recent revaluation date. The current valuation date is 1 April 2022, used for chargeable periods from 2023/24 to 2027/28. The next valuation date is 1 April 2027, which becomes the operative value from 2028/29 onwards. London capital values have not been uniform across the 2022 to 2027 cycle, but a meaningful share of high-end residential has moved up at least one band. A flat that was valued at £1.9m on 1 April 2022 and is plausibly £2.2m on 1 April 2027 moves from the £1m to £2m band (£9,450 in 2026/27 prices) to the £2m to £5m band (£32,200 in 2026/27 prices). The decision to commission a 1 April 2027 valuation, to model the band shift, and to consider Pre-Return Banding Check (PRBC) routes is one that fits naturally into a 2026/27 review.

The second is the band uplift. ATED bands are indexed annually by reference to the Consumer Prices Index for the year ended in the previous September. The 2026/27 figures, published by HMRC and verified against gov.uk, are:

Property value on the relevant valuation date Annual charge 2025/26 Annual charge 2026/27
More than £500,000, up to £1m£4,450£4,600
More than £1m, up to £2m£9,150£9,450
More than £2m, up to £5m£31,050£32,200
More than £5m, up to £10m£72,700£75,450
More than £10m, up to £20m£145,950£151,450
More than £20m£292,350£303,450

The uplift is modest in percentage terms, around 3.4 per cent, but the absolute numbers at the top of the table (£11,100 of extra annual charge in the over-£20m band) make the case for tightening relief claims and confirming filing discipline.

The third pressure is the HMRC compliance posture. HMRC's One-to-Many (OTM) letter campaign on ATED, which started in 2024, is now into its second cycle. The letters are not assessments; they are nudges sent off the back of a data match between Land Registry titles held in corporate names and ATED filings on record. They typically give the recipient 30 days to respond and they materially affect the prompted-versus-unprompted-disclosure penalty position under FA 2009 Sch 55. Sessions advising overseas-company holders should treat the OTM cycle as a baseline assumption, not an outlier event. The penalty cascade page walks through how the FA 2009 Sch 55 schedule applies once a return is overdue.

The Chargeable Persons Cohort: Who ATED Actually Catches

The single most common ATED misunderstanding is over scope. The regime is sometimes described as covering "all company-held UK residential property", which is wrong. ATED catches a tightly defined population, and getting the cohort right is the first step in any strategic review.

The Three Statutory Groups

Part 3 Finance Act 2013 (sections 94 to 174) imposes ATED on three classes of holder of UK residential property, collectively described as non-natural persons:

  • Companies, whether UK-incorporated, UK-resident-non-UK-incorporated, or wholly overseas. A Jersey company holding a Belgravia townhouse and a Manchester-incorporated Ltd holding a Salford flat are both in scope on identical statutory grounds.
  • Partnerships with at least one corporate member. A general partnership of two individuals is outside ATED. Add a corporate general partner (a common limited-liability structuring move for family partnerships) and the partnership becomes a non-natural person for the regime. LLPs with corporate members are caught on the same basis.
  • Collective investment schemes, including UK authorised investment funds, unauthorised property unit trusts, and overseas funds that hold a UK residential dwelling above the threshold.

Who Falls Outside

The corollary cohort is just as important for strategic work:

  • Individuals owning in their own name, including jointly with another individual, are outside ATED entirely. Husband-and-wife joint ownership, regardless of property value, is not within scope.
  • Trustees holding the dwelling on trust for individual beneficiaries are outside, provided no corporate trustee or corporate trust structure produces a non-natural-person owner at the relevant legal title level.
  • Bare nominee companies holding for an individual beneficial owner are outside, because beneficial ownership rests with the individual. The point is well established in the HMRC ATED Manual, but documentary evidence (a written declaration of trust pre-dating any enquiry) materially affects how robust the position is on challenge.
  • Charities holding the dwelling on charitable trusts can apply s.150 FA 2013 Charitable Use Relief; they remain technically within the regime but the relief reduces the charge to nil, subject to filing discipline.

The Single-Dwelling, £500,000 Threshold

ATED bites only on a single-dwelling interest worth more than £500,000 on the relevant valuation date. Three sub-points matter strategically.

First, the £500,000 threshold is per dwelling, not per portfolio. A company holding twenty £400,000 flats is outside ATED entirely; the same company holding one £600,000 flat is in scope for that one flat. This is why ATED affects high-end London corporate holdings disproportionately and barely touches mid-market regional BTL portfolios.

Second, the single-dwelling test treats sub-divided properties as multiple dwellings (each tested separately) and treats two adjacent freeholds used as one home as a single dwelling. A multi-flat house held under one title is multiple dwellings; a townhouse with the lower ground floor under a separate freehold but used as one residence is one dwelling.

Third, the valuation date is the most recent five-yearly date or the acquisition date if later. For 2026/27, that is 1 April 2022 for properties held throughout, with acquisition values used for properties bought between revaluations. The pillar guide covers the valuation mechanics in operational detail; the strategic question for 2026/27 is what the 1 April 2027 revaluation will move.

The Three-Tax Interlock for Enveloped Residential Property

ATED is best understood not as a standalone charge but as the middle member of a three-charge regime that the legislature built around corporate envelopes for UK residential property. The three charges run at different moments, attach to different events, and use deliberately aligned relief lists. Reading them together is how a strategic posture decision actually gets made.

SDLT 15% on Acquisition: Schedule 4A Finance Act 2003

When a non-natural person buys a single UK dwelling for more than £500,000, Schedule 4A FA 2003 imposes a flat 15 per cent SDLT rate on the entire consideration, displacing the standard residential SDLT slice rates. A £1.5m purchase by a Ltd that does not qualify for a Sch 4A relief produces £225,000 of SDLT, against roughly £100,000 under the standard residential schedule and around £75,000 if an individual buyer benefits from any first-time-buyer or other relief.

The Sch 4A relief list is deliberately aligned with the ATED relief list: rental property let commercially, property developer trade, property trader, employee accommodation, charitable use, and so on. A property bought for commercial letting typically qualifies for SDLT relief at acquisition and ATED relief annually thereafter. The trap is the three-year clawback window: a Sch 4A SDLT relief claimed at acquisition can be unwound by a non-qualifying use within three years of completion, which is a longer tail than the annual ATED claim cycle. The 15% SDLT and ATED interaction guide walks through the clawback mechanic in detail.

ATED Annually: Part 3 Finance Act 2013

ATED bites every year on the chargeable period from 1 April to 31 March, with the return and any payment due by 30 April at the start of the period. The headline charges run from £4,600 (£500,001 to £1m band) to £303,450 (over £20m band) in 2026/27. Reliefs are claim-on-return: the property rental business relief, the property developer relief, the property trader relief, the farmhouse relief, the employee accommodation relief, the open-to-the-public relief, the charitable use relief, the registered social housing provider relief, and the demolition / conversion relief together cover the majority of corporate residential holdings in practice. A nil-relief return is still a return; the FA 2009 Sch 55 penalty cascade runs the same way on a missed claim-only return as on a missed tax-due return.

IHT Schedule A1 on Death: Inheritance Tax Act 1984

Schedule A1 IHTA 1984, enacted in the Finance (No. 2) Act 2017 with effect from 6 April 2017, looks through corporate, partnership, and trust envelopes that hold UK residential property. For a non-domiciled (or, after the April 2025 reforms, non-long-term-resident) individual who owns shares in an overseas company holding a UK dwelling, the shares are treated as UK situs assets to the extent of the dwelling's value. Death produces a UK IHT charge at 40 per cent on that value (less the nil-rate band and any reliefs), even though the legal title sits in a non-UK company.

Schedule A1 was the regime change that ended the historic motive for overseas-company envelopes around UK residential property for non-domiciled owners. The envelope no longer shelters the property from IHT, ATED bites annually inside the envelope, and the 15% SDLT bit at acquisition. The three-tax interlock is what drives the strategic conversation for any overseas-company-held London residential property.

Reading the Three Together

For a board reviewing a corporate-held UK residential property in 2026/27, the three taxes interlock in this sequence:

  • Acquisition: 15% SDLT was paid (or a Sch 4A relief was claimed) at the time of purchase. The clawback window may or may not still be open.
  • Annual holding period: ATED is due each 30 April. Whether a relief is claimed depends on use during the period. A change of use within the year (let then occupied, or vice versa) produces day-apportionment in the relief calculation.
  • Disposal or death: a sale produces a non-resident CGT charge (for overseas companies) or a CT-on-gains charge (for UK companies); a death of a non-long-term-resident shareholder produces Schedule A1 IHT exposure on the residential value.

The strategic question for a 2026/27 review is: given the three-charge profile across the expected holding period, does the corporate envelope still earn its keep, or does dis-enveloping (or a different restructure) produce a better net position?

What Has Moved Between 2025/26 and 2026/27

The regime itself is stable; the moving parts are the figures, the valuation cycle, and the compliance posture. Three concrete shifts matter for a 2026/27 review.

Bands Uplifted by CPI

The 2026/27 figures (set out in the table above) reflect the CPI uplift announced by HMRC in autumn 2025. The percentage uplift is around 3.4 per cent across all six bands, applied to the previous year's figures and rounded to the nearest £50 per HMRC's convention. There is no change to the band thresholds themselves (£500k, £1m, £2m, £5m, £10m, £20m). The pillar guide carries the indexation mechanic in detail.

1 April 2027 Revaluation Looming

2026/27 is the last chargeable period under the 1 April 2022 valuation cycle. The 1 April 2027 revaluation will become operative from 2028/29 and will run for five years to 31 March 2033 inclusive. The strategic implication for a 2026/27 review is the obvious one: any property near a band boundary needs a 1 April 2027 valuation commissioned in good time, and the Pre-Return Banding Check (PRBC) route is available for values within 10 per cent of a boundary. PRBC is HMRC's no-fee, advance-view process; a 2028/29 PRBC application can be lodged once the 1 April 2027 valuation is in hand.

OTM Compliance Letters in their Second Cycle

HMRC's One-to-Many campaign is now into its second annual cycle. The letters typically target overseas companies on Land Registry titles where HMRC's data warehouse suggests an ATED-relevant dwelling and no return on file. The letter is not an assessment but a nudge: respond within 30 days with a return, a relief claim, an out-of-scope explanation, or a confirmation of voluntary disclosure. The disclosure status (prompted versus unprompted) determines the penalty band under FA 2009 Sch 55. Advisers acting for overseas-company holders should assume the letter is possible at any time and should put a documentary file together pre-emptively rather than reactively. The penalty cascade page covers the disclosure-status mechanic.

One historic moving part worth flagging because it still appears in older competitor pages: ATED-related CGT was abolished from 6 April 2019 by Finance Act 2019. Pre-April-2019 gains on enveloped dwellings ran through a parallel CGT regime at 28 per cent. From 6 April 2019, gains on UK residential property held by non-resident companies fall within the standard non-resident CGT regime at TCGA 1992 s.1A and Schedule 1A, with rebasing to 5 April 2019 applied for the transition. Gains held by UK-resident companies fall within ordinary corporation tax on chargeable gains. Any 2026/27 page or competitor source that references a 28 per cent "ATED-CGT rate" is out of date.

Strategic Posture Choices for the Corporate Holder

A board reviewing a corporate-held UK residential property in 2026/27 has four broad postures available. The right one is highly fact-dependent, but each can be sketched cleanly.

Dis-Envelope

Dis-enveloping (sometimes called de-enveloping) means transferring the dwelling out of the company and into individual ownership, usually as a distribution in specie to the shareholder. For a high-value family home occupied by connected individuals where no ATED relief is available, the annual charge of up to £303,450 typically outweighs any benefit from corporate ownership, and dis-enveloping is the standard direction of travel.

The mechanics are not trivial. The dis-envelope itself can trigger:

  • SDLT on the market value of the property at the date of transfer, where consideration includes the assumption of debt or a distribution in specie of a property subject to a mortgage.
  • Corporation tax on chargeable gains where the property has appreciated since acquisition.
  • An income distribution charge on the shareholder where the property is distributed without consideration.
  • Stamp Duty Land Tax at the residential schedule on the eventual onward sale, if the shareholder then disposes.

The net position is highly case-specific. A long-held property bought for £400,000 and now worth £3m has a different dis-envelope profile from a recently acquired £3m property held at near-cost. The shareholder's residence and domicile status, the company's other assets, and any IHT planning that the envelope was originally (often poorly) designed to deliver all feed into the modelling.

Claim Relief Annually

For corporate property let to unconnected tenants on commercial terms, the Property Rental Business Relief under s.133 FA 2013 reduces the ATED charge to nil. The corporate envelope continues to make sense for income tax (the company pays CT on rental profit, not income tax through Section 24's restricted finance-cost relief), incorporation reasons (limited liability, internal reorganisation flexibility), and succession planning (shares pass on death, not the property itself).

The relief is claim-on-return, not automatic, and the connected-person test under s.1122 CTA 2010 is unforgiving: a director's adult child moving into the property for two months between tenants is a non-qualifying occupation that breaks the relief for the affected days, and the family-rent-set-at-market-value workaround does not cure the connection itself. The rental property relief mechanics guide walks through the connected-person test, vacancy treatment, and refurbishment-period mechanics.

Restructure

Restructuring sits between dis-enveloping and accepting the charge. Examples include:

  • Moving an overseas-company holding into a UK-resident corporate vehicle, removing the offshore taint but keeping the corporate envelope.
  • Adding a corporate general partner to a family partnership where the partnership is currently outside ATED but the long-term plan benefits from limited liability (note that this moves the partnership into ATED, not out, so the trade-off must be explicit).
  • Establishing a property rental business inside the existing company by genuinely letting the dwelling to an unconnected tenant on commercial terms, switching the relief position from "none available" to "Property Rental Business Relief available".
  • Transferring the property into a trust where the trust structure (UK-resident, no corporate trustee) takes the holding outside ATED but inside other IHT and CGT regimes.

Each of these is a fact-pattern-specific question that needs full modelling. The strategic point is that "do nothing" and "dis-envelope" are not the only options.

Accept the Charge

For some holdings, particularly those near the bottom of the £500,000 to £1m band where the charge is £4,600 a year, paying ATED and treating it as a cost of corporate ownership is the right answer. The relief mechanics may not fit (the property is not let, is not a developer trade, is not employee accommodation), but the wider corporate position justifies the envelope. Family offices holding a London pied-à-terre for visiting board members occasionally sit in this category; some property-development companies during a holding-and-design-build period sit in it too. The buy-to-let Ltd company pillar covers the broader corporate-versus-individual decision framework.
