SPVs and Offshore Structures for Property Investment: What You Need to Know

Holding investment property through a corporate vehicle rather than personally has become increasingly common, driven by the progressive withdrawal of mortgage interest relief for individuals, the relative attractiveness of the corporation tax rate, and the liability and succession planning benefits that a company wrapper provides. For internationally mobile investors and high-net-worth buyers, the structure question — UK limited company, offshore company, or personal ownership — is one of the most consequential decisions in property investing.

What Is a Special Purpose Vehicle?

A Special Purpose Vehicle (SPV) is a company established for the sole purpose of holding a specific asset — in the property context, typically one or more investment properties. The SPV holds legal title to the property, collects rents, pays expenses, and (if appropriate) borrows against the property.

The individual or group of individuals who own the property own shares in the SPV rather than the property directly. This distinction has significant legal and tax consequences.

Most UK property SPVs are private limited companies registered at Companies House, incorporated for the specific purpose of property holding and management. They are governed by the same corporation tax rules as any other UK company.

Tax Advantages of a UK SPV

Full mortgage interest deductibility. Unlike individual landlords subject to Section 24, a company can deduct mortgage interest in full as a business expense before calculating taxable profit. For a highly leveraged portfolio, this can dramatically improve post-tax yield.

Corporation tax rate. Companies pay 25% corporation tax on profits (19% for small profits below £50,000, with marginal relief between £50,000 and £250,000 — 2026 rates). This compares favourably with income tax rates of 40–45% for higher and additional rate taxpayers.

Retained profit reinvestment. Profits left within the company are only taxed at the corporation tax rate until they are extracted. This allows a company to reinvest rental profits and grow the portfolio without the immediate income tax cost that applies to individuals.

CGT on disposal. Companies do not pay CGT — they pay corporation tax on capital gains. The rate is the same as on trading income (25% main rate), but the company's base cost includes any capital improvements, and there is no restriction on relief available.

Transfer Costs When Incorporating

The principal barrier to using an SPV for existing properties is the cost of transferring those properties from personal ownership into the company.

Stamp Duty Land Tax. The transfer of a property from an individual to a company is treated as a market value purchase for SDLT purposes. The company pays SDLT at the relevant rates (including the 5% additional dwellings surcharge as of late 2024). On a £600,000 buy-to-let property, the SDLT cost of incorporation could exceed £35,000.

Capital Gains Tax. The transfer is a disposal by the individual at market value, triggering CGT on any gain since acquisition. For properties held for many years with substantial embedded gains, the CGT cost of incorporation can run to six figures.

The partnership exception. Where the property is held in a genuine partnership (two or more people operating as partners with documented profit-sharing arrangements), SDLT relief may be available on incorporation under the partnership-to-company provisions in the Finance Act 2003. However, this requires a genuine, pre-existing partnership — not a structure created retrospectively for the purpose of incorporation.

For new purchases, incorporating is straightforward — the company acquires the property directly. The decision is most complex for existing portfolios.

Annual Tax on Enveloped Dwellings (ATED)

Any corporate vehicle (UK or offshore) that owns UK residential property worth more than £500,000 must complete an ATED return and may pay an annual tax based on the property value. The ATED charges range from approximately £4,400 per year for properties worth £500,000–£1 million, to over £287,000 per year for properties over £20 million (2025/26 rates, uprated annually for CPI).

ATED relief is available where the property is:

• Let to unconnected third parties on a commercial basis (rental relief)
• Held for development and sale (development relief)
• A farmhouse occupied by a farm worker
• Open to the public

Most genuine investment properties held by SPVs will qualify for rental relief from ATED, but the return must still be submitted and the relief claimed. Failure to file returns attracts penalties.

Offshore Company Ownership of UK Property

Before 2017, non-UK domiciliaries could hold UK residential property through an offshore company without being subject to IHT on the value of the property — because shares in a foreign company were excluded property for IHT purposes, even if the underlying asset was UK real estate. This gave rise to widespread use of British Virgin Islands, Jersey, Cayman Islands, and other offshore SPVs for high-value UK residential property.

From April 2017, HMRC changed the rules: UK residential property held through any structure — including an offshore company — is now subject to UK IHT in the hands of the ultimate beneficial owner. The "look-through" rule effectively pierces the corporate veil for IHT purposes.

This significantly reduced the IHT advantage of offshore structures for UK residential property. The remaining advantages are primarily:

• Non-UK property: offshore holding of non-UK property (for example, Spanish, Thai, or UAE real estate) may still provide IHT and succession planning benefits depending on the jurisdiction
• Privacy: offshore structures provide some privacy (the property appears in the land register as owned by a company, not the individual), though beneficial ownership registers have significantly reduced this
• Local succession law avoidance: an offshore company owning foreign property can, in some circumstances, simplify succession by passing shares in the company rather than dealing with foreign inheritance procedures directly
• Commercial property: offshore holding of UK commercial property does not trigger the look-through IHT rules in the same way

ATED and Offshore Structures

An offshore company owning UK residential property with a value above £500,000 is subject to ATED in exactly the same way as a UK company. Relief must be claimed where applicable. The offshore domicile of the company does not exempt it from ATED obligations.

The Mortgage Question

Buy-to-let mortgage availability for limited companies has expanded substantially over the past five years. Most major lenders now offer company buy-to-let products, though:

• Interest rates are typically 0.1–0.5% higher than equivalent individual products
• Lender criteria may require personal guarantees from directors
• Some lenders restrict lending to "purpose-built" SPVs with specified SIC codes (company activity codes)

For new purchases through an SPV, mortgage finance is generally available, though the universe of lenders is smaller than for personal mortgages.

Succession and IHT Planning with SPVs

Shares in a property investment SPV are personal property and can be held in trusts, gifted, or otherwise transferred as part of an IHT planning strategy. The key distinction from direct property ownership:

• Shares can be given away in smaller tranches (fractions of the total shareholding)
• Shares can be transferred without SDLT (unlike direct property transfers, which trigger SDLT on the market value)
• If the company qualifies as a trading company (for example, it provides services and is not purely passive investment), Business Property Relief may apply — though pure investment property companies do not qualify

For families building generational wealth in property, the SPV structure offers more flexibility for succession than direct personal ownership.

Practical Considerations

Multi-property SPVs vs single-property SPVs. A single SPV can hold multiple properties, or each property can have its own SPV. A portfolio in one company is simpler administratively but creates cross-contamination of liabilities. Individual SPVs provide liability ring-fencing but multiply compliance costs.

Shareholder structure. Consider from the outset who will hold shares in the SPV — family members, trusts, a holding company above the SPVs. The initial structure is far easier to establish correctly than to change later.

Ongoing compliance costs. Companies require annual accounts, corporation tax returns, Companies House confirmations, and (above certain thresholds) audit. These costs typically run to £1,500–£5,000 per company per year.
