How you legally hold your UK property investments is not a bureaucratic afterthought. It is one of the highest-value tax planning decisions you will make as a landlord. Get it right and your portfolio is positioned for sustainable, tax-efficient growth. Get it wrong and you could face a materially higher tax bill every single year.

For many investors, this decision became urgent after Section 24 of the Finance Act 2015 phased out full mortgage interest relief for individual landlords, a change that came into full effect in April 2020 and continues to drive significant tax liability today. Further changes introduced through the Autumn Budgets of 2024 and 2025 have added new layers of complexity around capital gains tax (CGT), stamp duty land tax (SDLT), and inheritance tax (IHT).

This guide provides a thorough, up-to-date comparison of personal and corporate property ownership, covering the real tax numbers, the HMRC rules that apply in 2025/26, and the key questions every landlord should be asking before deciding on a structure.

For high-net-worth investors building or managing substantial UK property portfolios, one of the most critical strategic decisions is how those assets are owned. The choice between personal ownership and corporate structures is not simply administrative. It directly impacts tax efficiency, long term wealth preservation, financing flexibility, and succession planning.

As portfolios grow in value and complexity, the limitations of holding property in a personal name often become more apparent. At the same time, corporate structures introduce their own considerations, including compliance, cost, and strategic planning requirements. Understanding how these approaches differ is essential for making informed, future proof decisions.

This guide explores the key tax and structuring considerations for UK property investors and outlines when each approach may be optimal.

Personal Property Ownership and What the Tax Rules Actually Say

How rental income is taxed in personal ownership

When you hold buy-to-let property in your own name, net rental profit is added to your other income and taxed at your marginal income tax rate. For 2025/26, the bands are:

• Basic rate: 20% on taxable income up to £50,270
• Higher rate: 40% on income between £50,271 and £125,140
• Additional rate: 45% on income above £125,140

An important but frequently overlooked consequence is that rental income can push investors into a higher tax band or erode their personal allowance. The personal allowance (£12,570 for 2025/26) tapers by £1 for every £2 of income above £100,000, creating an effective 60% marginal rate between £100,000 and £125,140. Landlords with growing portfolios often cross this threshold without realising it.

The Section 24 mortgage interest restriction, fully in force since 2020

This is where personal ownership creates the greatest financial disadvantage for leveraged landlords. Under Section 24 of the Finance Act 2015, individual landlords can no longer deduct mortgage interest directly from their rental income when calculating taxable profit. Instead, they receive a basic-rate tax credit worth 20% of their finance costs, regardless of whether they pay tax at 40% or 45%.

The practical effect is significant. Higher-rate taxpayers who previously received 40% relief on mortgage interest now receive only 20% relief. For heavily mortgaged portfolios, this can mean paying income tax on a profit figure that overstates true cash profit, or even paying tax in years where real cash profit is minimal.

Section 24 does not apply to limited companies. This asymmetry is one of the primary reasons portfolio investors have moved toward corporate structures since 2017.

Important: The Section 24 restriction also affects adjacent reliefs. If rental income calculated without the mortgage interest deduction pushes an investor’s adjusted net income above £60,000, the High Income Child Benefit Charge begins to apply, with full withdrawal of child benefit at £80,000. These knock-on effects are frequently missed in basic tax planning.

Capital gains tax on disposal of personally held property

When you sell a buy-to-let property held in your own name, the gain is subject to CGT at the residential property rates. As of 2025/26, following the changes announced at Autumn Budget 2024:

• Basic-rate taxpayers: 18%
• Higher and additional-rate taxpayers: 24%

The annual CGT exemption stands at just £3,000 for 2025/26, down from £12,300 in 2022/23. This means a much larger portion of any gain is now subject to tax than would have been the case just a few years ago. Residential property disposals must be reported to HMRC and any CGT paid within 60 days of completion, even if you already file a Self Assessment return. Failure to report on time can result in penalties and interest.

When personal ownership still makes sense

Personal ownership is not always the inferior choice. It remains appropriate in a range of situations:

• Smaller portfolios generating modest net profit where the investor sits firmly in the basic-rate band
• Investors who prioritise simplicity and want to avoid company compliance requirements
• Short-term investment strategies where property will be sold within a relatively short window
• Basic-rate taxpayers where the Section 24 restriction causes little or no additional tax
• Situations where the investor’s spouse or civil partner holds property in a lower-tax position

The key principle is that personal ownership becomes progressively less efficient as portfolio size, leverage, and personal income increase. What works at the start of an investment journey often needs reviewing as the portfolio grows.

Making Tax Digital is already changing personal landlord compliance From 6 April 2026, landlords with qualifying gross rental income above £50,000 must comply with Making Tax Digital for Income Tax Self Assessment (MTD for ITSA). This means using MTD-compatible software and submitting quarterly income and expense updates to HMRC, rather than a single annual Self Assessment return. The threshold drops to £30,000 from April 2027. This significantly increases the ongoing compliance burden of personal ownership and is a practical factor to weigh when comparing personal and corporate structures.

Important: New rental income tax rates confirmed from April 2027 Autumn Budget 2025 confirmed that from 6 April 2027, rental income from personally held property will be taxed at new, higher rates: 22% (basic rate), 42% (higher rate), and 47% (additional rate). These are separate from and higher than the standard income tax rates that apply to employment or pension income. These new rates do not apply to profits within a limited company, which continues to pay corporation tax at 19% to 25%. This change significantly widens the tax gap between personal and corporate ownership, particularly for higher and additional rate taxpayers.

Corporate Structures for Property and Current HMRC Rules

How rental profits are taxed in a limited company?

When property is owned through a UK limited company, most commonly an SPV (Special Purpose Vehicle), rental profits are subject to corporation tax rather than income tax. The current rates for 2025/26 are:

• Small profits rate: 19% on profits up to £50,000
• Main rate: 25% on profits above £250,000
• Marginal relief applies between £50,000 and £250,000, with an effective marginal rate of 26.5% within this band

These thresholds are divided proportionally if a company has associated companies, something to bear in mind when planning group structures. For most higher-rate taxpaying landlords, even the main 25% corporation tax rate represents a meaningful saving over the 40% or 45% income tax rates they would pay personally. The gap is widest for additional-rate taxpayers and for investors who retain profits within the company rather than extracting them immediately.

Full mortgage interest deductibility

Unlike individual landlords, limited companies are not subject to the Section 24 restriction. Mortgage interest and other allowable finance costs remain fully deductible from rental income as a business expense, reducing the company’s taxable profit before corporation tax is applied. This is a fundamental structural advantage for leveraged portfolios and the single most commonly cited reason investors incorporate.

The profit extraction question and the double tax reality

Corporate ownership does not eliminate personal tax. It defers and restructures it. When a director-shareholder wishes to access profits from a property company, they typically do so through a combination of salary and dividends, which creates a second layer of taxation:

• Dividends are taxed at 10.75% (basic rate), 35.75% (higher rate), or 39.35% (additional rate) after a £500 dividend allowance. Note: the basic and higher rates increased by 2 percentage points from 6 April 2026.
• The combination of corporation tax plus dividend tax can result in a higher overall effective rate than personal ownership for investors who draw out most profits each year

The corporate structure therefore works best from a pure tax efficiency standpoint when profits are retained and reinvested rather than extracted. For investors focused on portfolio growth, this is a natural fit. For those who rely on rental income to fund their lifestyle, the arithmetic needs careful modelling before assuming incorporation is the right move.

SDLT for companies and the surcharges that matter

Companies purchasing residential property pay the standard SDLT rates plus a 5% surcharge, increased from 3% in October 2024. For residential properties valued above £500,000 purchased by corporate bodies, a separate 17% flat SDLT rate may apply under ATED-related rules, though this is subject to exemptions for genuine property rental businesses.

Acquiring property through a company carries a higher upfront SDLT cost than personal purchase in most cases. This must be factored into the overall investment analysis before assuming that corporate ownership is automatically more tax-efficient. You must seek Professional SDLT Advice.

Transferring existing personally held property into a company

Many landlords with existing personal portfolios explore incorporating, meaning transferring properties from their own name into a limited company. This is a complex area with significant tax consequences that are frequently underestimated.

HMRC treats the transfer as a disposal at market value, even if no cash changes hands. This can trigger:

• CGT on the accrued gain at 18% or 24% for residential property in 2025/26
• SDLT at market value plus the 5% surcharge, payable by the company
• A requirement to refinance, as most lenders will not transfer personal mortgages to a company

Incorporation Relief under Section 162 of the Taxation of Chargeable Gains Act 1992 may allow CGT to be deferred by rolling the gain into the base cost of shares issued by the company. However, the conditions are strict: the property activity must constitute a business rather than a passive investment, and HMRC has challenged claims where the level of management activity is low. Case law, notably Ramsay v HMRC (2013), suggests that active management of approximately 20 hours or more per week may be required to qualify.

Important update for April 2026: Under proposals in Finance Bill 2025/26, Incorporation Relief will no longer apply automatically. It must be actively claimed in the Self Assessment return for the year of transfer from 6 April 2026. Correct documentation and professional advice are essential before proceeding. HMRC has also explicitly warned against marketed schemes using limited liability partnerships (LLPs) to avoid SDLT and CGT on incorporation. See HMRC Spotlight 69.

Financing	Wider mortgage product availability	SPV mortgages, often at higher rates
Succession planning	More complex; requires advice	Share transfers offer greater flexibility

Inheritance Tax Planning and What Has Actually Changed

Inheritance tax planning remains one of the most compelling reasons to plan property ownership carefully. UK IHT is charged at 40% on the value of an estate above the nil-rate band, currently £325,000, with the additional Residence Nil-Rate Band of up to £175,000 where a family home is left to direct descendants.

For large property portfolios held personally, the full market value of all properties forms part of the taxable estate. This can generate a very substantial IHT liability for beneficiaries.

Corporate structures can offer more flexibility in succession planning. Shares in a property company can be transferred or gifted more gradually, and family investment company structures allow controlled transfer of economic value while retaining management control. However, it is important to understand that shares in a property investment company do not attract Business Property Relief (BPR), because holding property as an investment is specifically excluded from BPR under HMRC rules. Claims that corporate structures can routinely mitigate IHT exposure through BPR on property investment companies are inaccurate and should be treated with caution.

BPR update from April 2026: Reforms announced at Autumn Budget 2024 and amended in late 2025 cap the 100% BPR and APR relief at £2.5 million per person, transferable between spouses giving up to £5 million per couple, from 6 April 2026. Excess value above this threshold qualifies for 50% relief only. These changes do not affect standard residential property investment portfolios, which remain ineligible for BPR regardless of whether they are held personally or corporately.

Genuine IHT planning for large property portfolios typically involves specialist trust structures, lifetime gifting within the seven-year rule, or professional estate planning advice. Simply incorporating a portfolio into a company does not by itself resolve IHT exposure.

Hybrid Structures and the Pragmatic Approach for Established Investors

In practice, many experienced UK landlords neither hold everything personally nor incorporate everything. A hybrid approach, holding legacy properties personally while directing new acquisitions into a corporate structure, allows investors to avoid the upfront CGT and SDLT costs of incorporating existing properties while benefiting from the corporate tax advantages on future growth.

This approach also offers flexibility. Different parts of the portfolio can be structured according to their purpose: residential buy-to-lets in an SPV, commercial properties through a different vehicle, and short-term furnished lets assessed individually following the abolition of the Furnished Holiday Let regime from April 2025.

The key discipline with hybrid structures is ensuring that each element has a clear commercial rationale and that the overall approach is documented and reviewable. HMRC has increased its scrutiny of property structures in recent years, and arrangements that lack genuine commercial substance can be challenged.

Common Mistakes and What HMRC Actually Scrutinises

Several recurring errors create unnecessary risk for landlords restructuring their portfolios:

• Incorporating without modelling the full CGT and SDLT costs of the transfer, which can outweigh several years of tax saving
• Assuming Incorporation Relief will apply without meeting the property business test under HMRC guidance and case law
• Using promoted LLP or partnership schemes to avoid SDLT on incorporation, specifically flagged in HMRC Spotlight 69
• Overstating the IHT benefits of corporate structures, as investment property companies do not qualify for Business Property Relief
• Failing to report residential property CGT within 60 days of completion
• Building group structures of unnecessary complexity without clear commercial purpose, which HMRC may challenge
• Not seeking specialist tax advice before restructuring; a general accountant may not have the specific expertise required for property tax planning of this nature

Key Questions to Ask Before Making Your Decision

There is no universal answer to the personal vs corporate question. The right structure depends on factors specific to each investor. Before deciding, or before discussing options with an adviser, work through the following:

1. What is your current and projected marginal income tax rate, and does rental income push you into a higher band?
2. How leveraged is your portfolio? The more significant your mortgage interest costs, the greater the Section 24 disadvantage in personal ownership.
3. Are you primarily extracting profits now, or reinvesting for growth? Corporate structures benefit reinvestors most.
4. What is your intended exit strategy: sale of individual properties, or eventual sale or transfer of the company as a whole?
5. What are your succession objectives? Who will inherit, and over what timeframe?
6. Can you absorb the upfront CGT and SDLT costs of incorporating an existing portfolio, or would it be more effective to acquire new properties within a company going forward?
7. What are the additional compliance costs of running a company, and are these proportionate to the tax saving at your portfolio size?

Frequently Asked Questions

Does a limited company pay CGT or corporation tax when it sells a property?

Companies do not pay CGT. They pay corporation tax on all profits including gains from property disposals. The gain is included in the company’s taxable profit for the relevant accounting period and taxed at the applicable corporation tax rate, between 19% and 25%.

Is it always better to buy property through a company?

No. The tax benefit depends heavily on your personal income tax position, how leveraged the portfolio is, whether you intend to extract or retain profits, and what your long-term exit strategy is. For basic-rate taxpayers with modest leverage, personal ownership may be equally or more efficient once the additional SDLT cost and compliance burden of a corporate structure are factored in.

Can I avoid SDLT when transferring my properties into a company?

In most cases, no. HMRC treats the transfer as a disposal at market value and SDLT is payable by the company accordingly, including the 5% surcharge. Certain partnership-to-company routes have been marketed as SDLT-efficient, but HMRC has specifically flagged these arrangements as avoidance schemes in Spotlight 69 and challenges them actively. Professional advice from a specialist is essential before pursuing any such route.

Does incorporating my property portfolio reduce inheritance tax?

Not automatically. Residential property investment companies do not qualify for Business Property Relief, so IHT exposure on the value of the company’s underlying property assets remains broadly similar whether held personally or corporately. The flexibility offered by corporate structures relates mainly to how shares can be transferred, not whether the underlying assets are IHT-exempt. Specialist IHT planning involves trust structures and professional estate planning advice.

What happened to the Furnished Holiday Let tax regime?

The Furnished Holiday Let (FHL) regime was abolished from 6 April 2025. FHL properties no longer benefit from the previous advantageous tax treatment, including the exemption from the Section 24 mortgage interest restriction. From April 2025, holiday let income is taxed in the same way as standard residential rental income for individual landlords.

When does a corporate structure become the better choice?

Corporate structures tend to become more compelling when a landlord is a higher or additional-rate taxpayer, has significant mortgage finance on the portfolio, plans to reinvest profits rather than extract them, is building toward a larger multi-property portfolio, or has succession and wealth transfer objectives that benefit from a shareholding structure. The decision should always be modelled against the investor’s specific numbers with qualified advice.

What is an SPV and how does it differ from a standard limited company?

An SPV, or Special Purpose Vehicle, is a limited company set up for a specific purpose, in this context to hold a single property or a defined group of properties. It operates under the same legal and tax framework as any other UK limited company but is ring-fenced from other assets and liabilities. Many lenders prefer SPV structures for buy-to-let mortgage applications as they offer cleaner security. Some investors use multiple SPVs held under a single holding company to separate risk across their portfolio.

Conclusion: Structure Your Portfolio for the Long Term

The tax landscape for UK property investors has changed substantially since 2015 and continues to evolve. Personal ownership remains a valid and sometimes optimal approach for smaller portfolios and basic-rate taxpayers. For higher-rate taxpayers with leveraged portfolios and long-term growth ambitions, the structural disadvantages of personal ownership have become increasingly difficult to ignore.

Corporate structures offer real tax advantages, particularly around mortgage interest relief and retained profit reinvestment, but they are not cost-free. The decision to incorporate an existing portfolio involves upfront tax costs that must be carefully modelled against the projected annual tax saving. The benefits are clearest for new acquisitions placed directly into a limited company from the outset.

A hybrid approach, keeping legacy properties personally held while acquiring new properties through a company, is increasingly the pragmatic choice for established investors who want to move toward a more efficient structure without triggering immediate tax liabilities on existing holdings.

Whatever your current position, the most important next step is a thorough review of your portfolio with a qualified property tax specialist who can model the real numbers for your specific circumstances and provide advice grounded in current HMRC guidance and legislation.
