Corporate Structures for Property Investors: A Practical Guide

The tax landscape for individual property investors in the UK changed fundamentally with the phased introduction of Section 24 (mortgage interest restriction) between 2017 and 2021. For higher-rate and additional-rate taxpayers with mortgaged property portfolios, personal ownership has become considerably less tax-efficient. Corporate and partnership structures have grown significantly as a result.

This guide explains the main structural options for serious property investors, including UK companies, LLPs, and overseas holding arrangements.

Why Structure Matters

Before exploring the options, it is worth understanding what is at stake.

A higher-rate taxpayer with a rental property generating £30,000 per year in rent, against which there is a £300,000 mortgage at 5% interest (£15,000 per year), illustrates the problem:

• Before Section 24: taxable rental profit = £30,000 - £15,000 = £15,000. Tax at 40% = £6,000.
• After Section 24: taxable rental profit = £30,000 (no interest deduction). Tax at 40% = £12,000. Less the 20% tax credit of £3,000. Net tax = £9,000.

The Section 24 restriction has increased the tax cost by 50% in this example. For a highly geared portfolio, the effect can be even more dramatic — some landlords find themselves paying tax on a paper profit while actually making a cash loss.

A company, by contrast, can deduct the full interest cost against taxable rental income.

The Special Purpose Vehicle (SPV)

An SPV is a separate limited company created specifically for a single property purchase or investment. Each property sits in its own company.

Tax treatment. Mortgage interest is fully deductible inside a company. The company pays corporation tax on net rental profit at 25% (for profits above £250,000) or at the lower rate applicable to smaller companies. For a property generating £15,000 net profit (after interest), the corporation tax bill at 25% is £3,750 — significantly lower than the £9,000 in the personal ownership example above.

SDLT. The additional 5% Stamp Duty Land Tax surcharge (raised from 3% to 5% on 31 October 2024) applies to company purchases of residential property in the same way as for individuals buying second properties. There is no surcharge exemption for using a company. For commercial property, standard SDLT rates apply without an additional surcharge.

Non-resident directors. A UK-registered company does not face the 2% SDLT non-resident surcharge even if its directors are non-UK resident — the surcharge applies to individuals, not UK-registered companies. This is an advantage for non-resident investors using a UK company to hold UK residential property.

Advantages of separate SPVs. Individual SPVs provide cleaner separation — useful if you intend to sell one property without affecting the others, or if you want different investors in different properties. However, separate SPVs mean separate accounting, banking, and administration costs.

The Portfolio Holding Company

Instead of separate SPVs, many investors use a single company to hold multiple properties. This is simpler to administer and may offer better terms from lenders (some lenders look at the portfolio company's overall track record rather than individual property performance).

One consideration is the "connected company" rules for SDLT. If the same individual owns multiple companies that are acquiring properties as part of a series of transactions, HMRC may treat these as "connected" and apply the higher SDLT rates that apply to bulk property purchases. Professional advice should be taken where multiple connected entities are acquiring property.

The Limited Liability Partnership (LLP)

An LLP is a hybrid structure — it provides limited liability (like a company) but is tax-transparent (like a partnership). Income and gains in an LLP are attributed directly to the partners and taxed at their individual rates.

Why an LLP for property? The LLP's transparency means that Section 24 does not apply — the partners are treated as carrying on the property business directly, and mortgage interest remains fully deductible against their share of the rental income. This is a significant advantage over personal ownership while preserving partnership flexibility.

Partnership tax rates apply. Each partner pays income tax on their share of the LLP's profit at their own marginal rate. This may be less advantageous than a company where the 25% corporate rate is lower than an individual's 45% additional rate. But for partnerships where one partner is a basic-rate taxpayer and the other is not, the LLP allows income to be allocated efficiently between partners.

Internationally mobile families. An LLP is particularly useful for property-owning families where partners have different tax residencies or marginal rates. A UK-resident higher-rate taxpayer partnered with a non-UK resident spouse (who may have lower UK income) can allocate rental income to the lower-rate partner — subject to the partnership rules allowing legitimate commercial allocation.

Overseas Holding Companies

Historically, some UK property was held through overseas companies — typically in the British Virgin Islands, Cayman Islands, or Cyprus — to achieve tax advantages. The tax landscape for overseas companies holding UK property has been largely closed down by successive Finance Acts.

Annual Tax on Enveloped Dwellings (ATED). Residential properties worth over £500,000 held in companies (including overseas companies) are subject to ATED — an annual charge that scales with property value (from £4,600 per year for properties worth £500,000–£1m in 2026/27, rising annually with CPI, to over £290,000 per year for properties worth more than £20m). Commercial property is not subject to ATED.

Non-Resident Capital Gains Tax (NRCGT). All non-UK resident sellers of UK real property — including overseas companies — have been subject to NRCGT since April 2019. The rate is broadly equivalent to the UK's main CGT rate for residential property (24% for companies). The pre-2019 historical base-date election limits the NRCGT exposure, but future gains are fully within scope.

What remains for overseas structures. The case for offshore holding of UK residential property is now very limited for most investors. The costs (ATED, NRCGT, corporate tax, additional SDLT) typically outweigh any remaining advantages. For commercial property, the position is more nuanced — an offshore company still avoids the 3% additional SDLT surcharge (which applies only to residential property), and there may be specific structuring reasons for an overseas holding entity in complex corporate transactions. Specialist advice is essential.

Cyprus holding companies. Cyprus, as an EU and DTA treaty partner of the UK, is used by some internationally structured investors. The Cyprus-UK Double Tax Agreement may reduce withholding taxes on certain income flows. However, the UK's ring-fencing of UK property gains and income means that the Cyprus structure provides limited benefit for UK property specifically. Cyprus holding structures are more useful for non-UK investments held by UK-connected individuals.

Tax on Extracting Profits from the Company

One aspect of company ownership that is frequently underestimated is the cost of extracting profits. Inside the company, profits grow at 25% corporation tax. But to access those profits personally, you must pay additional tax:

• Dividends: taxed at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate) after the £500 dividend allowance.
• Salary: subject to PAYE and National Insurance.

The combined effective rate on company profits that are extracted as dividends can approach or exceed personal ownership rates, depending on the extraction strategy. The company structure is most efficient where:

• Profits are retained and reinvested rather than fully extracted each year.
• Dividends are paid to lower-rate taxpayers (e.g., adult children who are shareholders).
• Profits are reinvested in further property acquisitions within the company.

Mortgages for Company Property

Lenders offering buy-to-let mortgages to limited companies have grown significantly, but there are still differences from personal ownership:

• Company mortgage rates are typically 0.1–0.4% higher than personal rates.
• Lenders require director guarantees, meaning the personal assets of the directors remain exposed.
• The company's accounts and the directors' personal financial position are both assessed.
• Deposit requirements are typically 25–30% of the property value.

Major specialist BTL lenders — including Paragon, Fleet Mortgages, Foundation Home Loans, and Aldermore — all have active company BTL product ranges.

Should You Transfer Existing Properties into a Company?

The question most frequently asked by landlords with existing personal portfolios is whether to move their properties into a company. In almost all cases, the answer is: no, or at least not directly.

Transferring an existing property from personal to company ownership constitutes a disposal at market value for CGT purposes and a purchase at market value for SDLT purposes. Both taxes are triggered at the point of transfer. For most existing portfolios, the combined CGT and SDLT cost of incorporation far exceeds the future tax savings of company ownership, making the exercise uneconomic.

The exception is where properties have very little CGT gain (recently purchased, or in a rising market with a high base cost) and/or where there is a legitimate incorporation relief available (rare in property investment contexts). Professional tax advice is essential before any transfer.

The company structure makes most sense for new acquisitions — future purchases are made through the company from the outset.

Important Considerations

Property investment via corporate structures involves significant complexity in tax, accounting, mortgage finance, and legal structure. This article is a general overview only and does not constitute financial or tax advice. Tax rules — including corporation tax rates, SDLT surcharges, ATED thresholds, and Section 24 — are subject to change. The right structure depends on your specific circumstances, tax position, and investment objectives. Always seek qualified independent advice from a tax specialist and property solicitor before establishing or modifying a property holding structure. Property values can fall as well as rise.
