Offshore Holding Structures for Real Estate: UK and International Property in 2025

Introduction: The Transformation of Offshore UK Property Holding

For two decades before 2013, holding UK residential property through an offshore company — typically a BVI or Cayman vehicle — was a legitimate and widely used tax planning strategy. The envelope structure (property held within a corporate "envelope") allowed non-UK domiciled individuals to hold UK real estate outside their estate for UK inheritance tax purposes and to defer capital gains tax on disposal.

The UK government systematically dismantled these benefits between 2013 and 2019. A series of legislative changes introduced the Annual Tax on Enveloped Dwellings (ATED), a 15% SDLT surcharge on corporate purchasers, non-resident capital gains tax on disposals, and ultimately the extension of inheritance tax to offshore structures holding UK residential property.

This guide traces the history of these changes, examines the current position, and identifies where offshore holding still makes commercial sense.

The Pre-2015 Benefits of Offshore UK Property Holding

Inheritance Tax Efficiency

UK IHT is charged at 40% on the death estate of UK-domiciled individuals, and on UK situs assets of non-UK domiciled individuals. Prior to April 2017, a non-UK domiciled individual could hold UK residential property through an offshore company. The company's shares were a foreign situs asset (the situs of shares in a foreign company is the jurisdiction of incorporation). The foreign situs shares were therefore outside the scope of UK IHT for a non-domiciliary.

Example (pre-2017): a non-dom individual holds a London house worth £5 million through a BVI company. On death, the BVI shares pass to heirs outside the UK IHT net. IHT saving at 40%: £2 million.

Capital Gains Tax Deferral

Prior to April 2015, non-residents disposing of UK residential property were not subject to UK CGT. A non-resident selling a UK house either directly or through an offshore company paid no UK CGT on the gain. This changed with the introduction of the Non-Resident Capital Gains Tax (NRCGT) from 6 April 2015.

Stamp Duty Efficiency (Historical)

Until the introduction of the 15% SDLT surcharge, buying a property through a company and then selling the company's shares (rather than the property) avoided Stamp Duty Land Tax on the second and subsequent transfers of the property, as the sale was of shares (0.5% stamp duty) rather than real estate (up to 7% at the time). This "enveloping" on acquisition was common pre-2012.

The Annual Tax on Enveloped Dwellings (ATED)

What ATED Is

ATED was introduced by Finance Act 2013 and applies to UK residential properties worth more than £500,000 that are owned by "non-natural persons" — companies, partnerships with corporate members, and collective investment schemes.

Current ATED Rates (2025-26)

Property Value	Annual ATED Charge
£500,001 – £1,000,000	£4,400
£1,000,001 – £2,000,000	£9,000
£2,000,001 – £5,000,000	£30,550
£5,000,001 – £10,000,000	£71,500
£10,000,001 – £20,000,000	£143,550
Over £20,000,000	£287,500

ATED is chargeable annually on the company, not the individual owner. An ATED return must be filed with HMRC by 30 April each year for properties held on 1 April that year.

ATED Reliefs

ATED does not apply (subject to claiming relief) where:

• The property is let to a third party on a commercial basis (rental relief)
• The property is being developed for resale (property developer relief)
• The property is used for property trading purposes
• The property is in a genuine property trading business

These reliefs must be claimed by filing an ATED relief return (Form ATED) — they are not automatic.

ATED-Related CGT

In addition to the annual charge, disposals of enveloped residential properties are subject to ATED-related CGT at 28% on the gain arising during periods when ATED applied without relief. This charge applies even to non-resident companies.

The 15% SDLT Surcharge on Corporate Purchasers

Finance Act 2012 introduced a 15% SDLT rate (higher rates for additional dwellings surcharge from 2016, now 17% for non-residents purchasing through companies) on the purchase by a company of residential property worth more than £500,000.

Current Position (2025)

A UK company or overseas company purchasing a residential property above £500,000:

Transaction	SDLT Rate
Residential property ≤ £500,000 (company)	Standard rates (3% surcharge on top)
Residential property > £500,000 (company purchasing to hold as investment)	15% flat rate
Non-resident company purchasing residential property > £500,000	17% flat rate (17% = 15% + 2% non-resident surcharge from 2021)

Relief from 15% rate applies where the property is acquired for rental, development, or trading — same reliefs as ATED. However, the relief must be claimed and maintained — if the property ceases to qualify (e.g., a developer retains the property post-development), the full SDLT becomes payable.

Non-Resident Capital Gains Tax

Residential Property: From April 2015

From 6 April 2015, non-residents (individuals, companies, trusts) disposing of UK residential property became subject to UK CGT (NRCGT) on the gain arising since 5 April 2015. Prior gains are generally outside the charge (using April 2015 market values as the base cost for NRCGT purposes, or the original acquisition cost if more favourable under rebasing).

Rate for non-resident companies: the NRCGT rate for non-resident companies was initially 20%, then aligned with the corporation tax rate (19%, now 25% for companies with profits over £250,000) from April 2019.

Commercial Property: From April 2019

From 6 April 2019, the scope of non-resident CGT was extended to all UK property — both residential and commercial — and to UK property-rich companies (companies where 75% or more of the asset value consists of UK land).

A non-resident company selling a UK commercial property now pays UK corporation tax on the disposal gain:

Company Profit Level	Corporation Tax Rate
Profits ≤ £50,000	19%
Profits £50,001–£250,000	Marginal relief applies
Profits > £250,000	25%

The Property-Rich Company Rule

This provision targets indirect disposals. If a non-resident sells shares in a BVI company that owns a UK property, and the BVI company is "property-rich" (75%+ UK land by value), the disposal of the BVI shares is treated as a disposal of UK property for NRCGT purposes. The non-resident shareholder is taxed on the gain on the shares attributable to the UK land.

This effectively closes the historical structure of selling the offshore corporate "envelope" rather than the property to avoid NRCGT.

Inheritance Tax: The Post-2017 Position

The April 2017 Change

Finance (No.2) Act 2017 introduced s.6A into the Inheritance Tax Act 1984, extending UK IHT to residential property held by closely-held companies (companies with five or fewer participators) where the property is otherwise held through an "excluded property" structure.

Effectively, from 6 April 2017, the use of offshore companies, trusts, or partnerships to hold UK residential property no longer provides an IHT advantage for non-UK domiciled individuals. The shares in the BVI company are no longer automatically excluded property if the underlying asset is UK residential property.

Current IHT Position for Non-Doms

Non-UK domiciled individuals holding UK residential property through an offshore company are within the scope of UK IHT on the value of the shares attributable to the UK residential property. The offshore corporate layer provides no IHT protection.

For non-doms with prior structures (established before 2017), the shares became within scope from 6 April 2017 — there was no grandfathering of the old position.

When Offshore Holding Still Makes Commercial Sense

Despite the systematic narrowing of UK tax benefits for offshore property holding, legitimate use cases remain:

Use Case	Why Offshore Vehicle Still Useful
Non-UK commercial property (no ATED, no residential SDLT surcharge)	Tax efficiency on disposal (no UK NRCGT if not UK-situated); governance flexibility; privacy
Non-UK buyers acquiring non-UK property	No UK tax nexus at all; offshore corporate holds non-UK asset efficiently
UK commercial property held by non-UK investors as institutional investment	Large institutional structures (REITs, fund structures) may still use offshore vehicles for specific purposes
Operational real estate businesses with genuine offshore nexus	Where management genuinely offshore, territorial tax advantages remain
Pre-IPO real estate holdings	Cayman or BVI holding companies for real estate portfolios prior to listing on overseas exchanges
Multi-jurisdiction property portfolios	Offshore holdco co-ordinates multiple property-owning subsidiaries in different countries

UK Residential Property: The Current Recommendation

For most non-UK domiciled individuals buying UK residential property in 2025:

• Do not use an offshore corporate wrapper for UK residential property
• The ATED annual cost (up to £287,500/year), the 17% SDLT on acquisition, NRCGT on disposal, and the loss of IHT protection make the offshore company structure commercially negative for UK residential
• Direct individual ownership, or UK trust structures for IHT planning purposes, are generally preferable

Practical Compliance for Existing Structures

Many clients hold UK property through offshore structures established pre-2013. For these:

ATED Compliance

• Annual ATED returns due by 30 April
• Properties must be revalued every 5 years (most recently April 2022; next April 2027)
• ATED relief returns required if the property qualifies for relief

NRCGT Returns

Non-resident companies disposing of UK property must file an NRCGT return (now a Corporation Tax return) within 60 days of completion. Late filing penalties apply.

Register of Overseas Entities (ROE)

Under the Economic Crime (Transparency and Enforcement) Act 2022, overseas companies owning UK land or property must register their beneficial owners at Companies House in the Register of Overseas Entities. Non-compliance renders the property incapable of disposition. Registration is required for property acquired from 1 January 1999.
