A UK property portfolio in a limited company retains full mortgage interest deductibility, unlike personal ownership which is restricted to 20% basic rate tax credit under Section 24 since April 2020. Corporation tax at 25% applies to profits above £250,000. The breakeven versus personal ownership typically occurs at three to five mortgaged properties where the annual tax saving exceeds the SDLT cost of incorporation, which can exceed £70,000 on a four-property portfolio valued at £1.4m.

Why Does the Limited Company vs Individual Decision Matter More in 2026?
The limited company versus individual ownership decision has become more consequential since 2020 because the full Section 24 restriction is now in effect, corporation tax has settled at 25% for larger company profits, and dividend tax rates have increased significantly since 2016. The combined effect is that neither structure is universally superior: the optimal choice depends on marginal tax rate, portfolio size, leverage level, and profit extraction intent.
The question is no longer whether to use a company in principle. For higher-rate taxpayers building a portfolio from scratch in 2026, a limited company is almost always the correct structure when rental income is being retained and reinvested rather than fully extracted. The real question is how to structure the company, whether to use a single entity or an SPV group, and how to manage the tax position on profit extraction efficiently. For a full explanation of property finance structures, see our complete property finance guide for UK investors.
Investors who already hold properties in personal names face a different question. They cannot restructure without triggering SDLT on the transfer, and in some cases capital gains tax on deemed disposal. The analysis must quantify the one-time costs against the present value of the future tax saving to determine whether restructuring is worthwhile.
What We See in Practice: The Structuring Decisions That Define Portfolio Outcomes
As CFO to a £205m property and care group, I have seen both the benefit of early corporate structuring and the cost of remedial restructuring after the portfolio has grown. The observations below are drawn from that direct experience and from advising landlords at every stage of portfolio development.
The most common costly mistake is buying the first three properties in personal names because it seemed simpler at the time, then discovering at property four that the portfolio generates £40,000 in rental income but only £12,000 in profit after Section 24, and that the SDLT to incorporate is now £45,000 to £55,000 on market values. At that point, the investor faces a 4 to 5 year payback period on the restructuring cost before any net benefit from incorporation. Many choose not to restructure and continue in an inefficient position indefinitely.
For investors starting fresh in 2026, I recommend a holding company with a single trading SPV for the first one to three properties, with the option to add further SPVs as the portfolio grows. The administration cost of this structure runs to approximately £2,000 to £3,500 per year in combined accountancy and Companies House fees, but the flexibility it creates is worth considerably more over a 10 to 15 year investment horizon. The holding company can hold cash, provide inter-company loans, and act as the investor's group treasury without itself being a mortgaged entity.
On profit extraction, investors often underestimate the cost of dividends. At 33.75% higher-rate dividend tax and 25% corporation tax, extracting £100,000 of profit from the company as dividends costs £25,000 in corporation tax and a further £25,313 in dividend tax on the £75,000 remaining, giving a combined effective rate of 50.3%. Reinvesting that £100,000 in the next acquisition avoids the dividend tax entirely. The most tax-efficient property company models maximise retention and reinvestment, extracting only what is needed for living costs, supplemented by a small PAYE salary using the personal allowance.
On mortgage access, the common concern that limited companies cannot access mainstream BTL mortgages is less accurate in 2026 than it was in 2019. Lenders including Shawbrook, Paragon, Foundation Home Loans, and Precise Mortgages have well-established SPV and limited company BTL products. The rate premium over personal-name mortgages is typically 0.5 to 1.0% rather than the 1.5 to 2.0% differential of earlier years. For a well-leveraged portfolio, this cost is recoverable within one to two years of corporation tax saving.
How Does Section 24 Change the Tax Calculation for Individual Landlords?
Section 24 of the Finance Act 2015 limits mortgage interest relief for individual buy-to-let landlords to the basic rate of income tax (20%), regardless of the landlord's marginal rate. This means a higher-rate taxpayer pays income tax at 40% on their full gross rental income, then receives only a 20% tax credit on the mortgage interest, not a 40% deduction. The practical effect is that a portion of the mortgage interest cost is funded from after-tax income rather than reducing taxable profit.
The impact is most severe for landlords with high leverage and modest yield. A landlord with £500,000 in rental income across a portfolio and £350,000 in mortgage interest has a real net profit of £150,000 before other deductions. Under Section 24, the full £500,000 is taxable at 40%, giving a gross income tax charge of £200,000. The 20% credit on £350,000 interest reduces this by £70,000, leaving net income tax of £130,000 against a real profit of £150,000. The effective tax rate is 86.7% of the real profit.
Where Section 24 pushes taxable income above the personal allowance threshold or into higher-rate bands, it can also affect child benefit clawback (beginning at £50,000 adjusted net income in 2026), student loan repayments, and pension annual allowance tapering. The Section 24 gross-up effect means individual landlords' apparent incomes are significantly higher than their real economic positions, creating collateral impacts across their personal tax position. Individual landlords with qualifying income above £50,000 must also keep digital records and file quarterly updates to HMRC under Making Tax Digital for Income Tax from 6 April 2026, adding a further compliance burden to personal-name ownership.
- Section 24 effective since: April 2020
- Relief available: 20% basic rate tax credit on mortgage interest only
- Higher-rate landlords: taxed at 40% on gross rental income, credit of 20%
- Additional-rate landlords: taxed at 45% on gross rental income, credit of 20%
- Collateral effects: child benefit, student loans, pension tapering all affected by gross-up
What Are the Corporation Tax Rules for a Property Portfolio Company?
A limited company holding buy-to-let properties pays corporation tax on its property rental profits after deducting all allowable business expenses, including mortgage interest in full. The corporation tax rates applicable from April 2023, and continuing into 2026, are 19% on profits up to £50,000, a marginal rate between £50,000 and £250,000, and 25% on profits above £250,000. The marginal rate between the thresholds is effectively 26.5% due to the tapered relief calculation.
Allowable deductions for a property company include mortgage interest and finance charges in full, letting agent fees, maintenance and repairs (capital improvements are not deductible but attract capital allowances in some cases), insurance, professional fees, property management costs, and director salaries at market rates. The company can also deduct the cost of any legitimate business expenses incurred in the management of the portfolio.
Property companies do not benefit from the main capital allowances regime that applies to trading companies, because residential property is specifically excluded from plant and machinery allowances. The exception is furnished holiday let properties (FHL), which have historically attracted capital allowances on furnishings and fittings. However, the FHL regime was abolished from April 2025, and properties that previously qualified as FHLs are now treated as ordinary property businesses for tax purposes.
- Corporation tax 2026: 19% on profits below £50,000
- Corporation tax 2026: 25% on profits above £250,000
- Marginal relief: tapered between £50,000 and £250,000 (effective 26.5% in the band)
- Mortgage interest: fully deductible as a business expense
- Capital allowances on residential property: generally not available
What Is the True Cost of Transferring an Existing Portfolio to a Limited Company?
Transferring an existing personal-name buy-to-let portfolio to a limited company triggers two potential charges: SDLT on the transfer at market value, and capital gains tax (CGT) on any gain between the original acquisition cost and the current market value. Both charges apply simultaneously on incorporation. This combined cost is the primary reason many existing landlords choose not to incorporate despite the ongoing tax disadvantage of personal ownership.
SDLT on residential property transfers to a connected company is charged at market value. The residential SDLT rates, including the 3% additional dwellings surcharge, are: 3% on the first £125,000, 5% from £125,001 to £250,000, 8% from £250,001 to £925,000, 13% from £925,001 to £1,500,000, and 15% above £1,500,000. On a portfolio of four properties at an average value of £350,000 (total £1,400,000), SDLT at these rates amounts to approximately £83,750 before any reliefs.
CGT applies on the deemed disposal at market value. The gain is calculated as current market value minus original acquisition cost minus allowable improvement costs and acquisition expenses. Residential property CGT rates are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers (following the Autumn 2024 Budget changes). For a portfolio acquired in 2010 with a base cost of £700,000 now valued at £1,400,000, the CGT on a higher-rate taxpayer would be approximately £168,000 on the £700,000 gain, before any principal private residence relief, lettings relief, or annual CGT exemption.
Partnership incorporation relief eliminates SDLT where a genuine property partnership exists and transfers to a company owned in the same proportions. CGT holdover relief under section 162 of the Taxation of Chargeable Gains Act 1992 can defer the CGT on the same transfer. Together these reliefs can make incorporation effectively cost-free. However, establishing a genuine partnership takes 12 to 18 months minimum, and HMRC challenge partnership arrangements that appear to have been created solely to access incorporation relief.
At What Portfolio Size Does the Limited Company Structure Break Even?
The breakeven analysis compares the annual tax saving from limited company ownership against the one-time cost of incorporation via SDLT and CGT. For a higher-rate taxpayer with three mortgaged properties generating £30,000 net rental income and £20,000 in mortgage interest, the annual Section 24 tax disadvantage (the extra tax paid due to the mortgage interest restriction) is approximately £4,000. On an SDLT cost of £35,000 to incorporate, the payback period is 8 to 9 years, which is likely too long to justify immediate restructuring.
With five mortgaged properties generating £60,000 net rental income and £40,000 in mortgage interest, the annual Section 24 tax disadvantage is approximately £8,000. On an SDLT cost of £65,000 to £80,000, the payback is 8 to 10 years. In this case, whether to incorporate depends heavily on the expected remaining investment horizon. An investor planning to hold for 20 years has a compelling case to restructure. An investor planning to exit in five years does not.
The breakeven becomes significantly more favourable where partnership incorporation relief is available. If SDLT is eliminated and CGT holdover is applied, the restructuring cost falls to professional fees of £5,000 to £15,000 for the restructuring advice and legal work. In this scenario, the payback period for a five-property portfolio is one to two years, making incorporation clearly worthwhile.
- Typical breakeven: 3 to 5 mortgaged properties where annual tax saving exceeds SDLT cost
- Without partnership relief: payback period of 8 to 10 years on a 5-property portfolio
- With partnership relief: payback period of 1 to 2 years on the same portfolio
- New portfolios built via a company: no breakeven calculation needed; use a company from day one
How Does Profit Extraction Work from a Property Limited Company?
Profit extraction from a property limited company is the most tax-sensitive element of the corporate structure. The three main routes are salary, dividends, and director loans. Each has a different tax treatment, and the optimal combination depends on the investor's total income, other sources of earnings, and personal allowance utilisation.
A salary paid to a director-investor is subject to income tax at the marginal rate and employer plus employee National Insurance contributions. However, a salary up to the primary threshold (£12,570 per year in 2026/27) uses the personal allowance without triggering income tax or NIC for the employee, and is a deductible expense for the company. Most property company directors pay themselves a salary of £12,570, using the personal allowance fully, and extract additional income via dividends.
Dividends are paid from after-corporation-tax profits. The dividend allowance in 2026/27 is £500, meaning the first £500 of dividends is tax-free. Above this, dividend tax is 8.75% for basic-rate taxpayers, 33.75% for higher-rate taxpayers, and 39.35% for additional-rate taxpayers. Combining a £12,570 salary with £37,700 in dividends (the full basic-rate band in 2026/27) results in a combined income tax and NIC charge significantly lower than if the same income were received as employment income, and much lower than the equivalent charge under Section 24 for a personal-name portfolio.
What Mortgage Options Are Available to Limited Company Landlords?
Limited company and SPV buy-to-let mortgages are available from a growing number of specialist lenders in 2026. The mainstream high-street BTL providers (Halifax, Nationwide, Barclays) generally do not lend to limited companies. Specialist BTL lenders with well-established limited company products include Shawbrook Bank, Paragon Mortgages, Foundation Home Loans, Precise Mortgages, The Mortgage Works, and Landbay.
The rate premium for limited company mortgages over equivalent personal-name mortgages was 1.5 to 2.0% in 2019. In 2026, this premium has compressed to typically 0.5 to 1.0% as lender competition in the SPV and limited company market has increased. At 0.75% above a personal-name rate, the additional annual interest cost on a £200,000 mortgage is £1,500. For a higher-rate taxpayer where the annual Section 24 saving exceeds this, the rate premium is recovered within the first year.
Lenders assess limited company applications against the same rental stress tests as personal-name applications, typically requiring rental income at 125 to 145% of the mortgage payment at a stressed rate of 5.0 to 5.5%. The LTV ceiling for standard residential BTL properties is 75%, unchanged from personal-name mortgages with most specialist lenders. Some lenders require the director-guarantor to provide a personal guarantee on the company mortgage.
Should New Property Investors Always Use a Limited Company?
New property investors who are higher-rate or additional-rate taxpayers should almost always use a limited company or SPV structure for buy-to-let properties purchased in 2026. The Section 24 restriction makes personal-name ownership structurally inefficient for investors above the basic-rate threshold, and there is no SDLT cost on new acquisitions made directly by the company.
Basic-rate taxpayers face a different calculation. Under Section 24, the basic rate tax credit exactly compensates for the restriction, so a basic-rate taxpayer does not lose anything from personal ownership. The additional complexity and cost of a limited company structure may not be justified for investors who expect to remain basic-rate taxpayers throughout their investment horizon. However, if growth in rental income is expected to push them into higher-rate tax, incorporating before that transition occurs is more efficient.
Investors who plan to pass the portfolio to the next generation should also consider a limited company from day one. A company holding property can be passed via share transfer, allowing use of business property relief, gifting strategies, and trust arrangements that are not available for direct property ownership. The estate planning advantages of corporate ownership compound over long hold periods and can be more valuable than the tax position during the investment phase.

Frequently Asked Questions: Property Portfolio in a Limited Company
Is a limited company better than personal ownership for buy-to-let in 2026?
For higher-rate and additional-rate taxpayers, a limited company is generally more tax-efficient because mortgage interest is fully deductible, unlike personal ownership under Section 24 where relief is capped at 20%. Basic-rate taxpayers see less benefit because the Section 24 credit fully compensates them. The decision also depends on whether the investor plans to reinvest profits (favours company) or extract all income immediately (narrows the advantage).
How much SDLT do I pay to transfer properties to a limited company?
SDLT is charged on market value at residential rates plus the 3% additional dwellings surcharge. On a property worth £350,000, SDLT is approximately £18,500. On four properties worth £1,400,000 in aggregate, the combined SDLT is approximately £83,750. Partnership incorporation relief can eliminate this charge where a genuine partnership has been in existence for at least 12 to 18 months before transfer.
Can a limited company get a buy-to-let mortgage?
Yes. Specialist lenders including Shawbrook, Paragon, Foundation Home Loans, Precise Mortgages, and Landbay offer BTL mortgages to limited companies and SPVs. Rates are typically 0.5 to 1.0% higher than equivalent personal-name products in 2026. Most mainstream high-street lenders do not offer limited company BTL mortgages.
What corporation tax rate applies to a property rental company?
Property rental companies pay corporation tax at 19% on profits up to £50,000 and 25% on profits above £250,000. A marginal tapered rate applies between £50,000 and £250,000, with an effective rate of 26.5% in that band. These rates have been in effect since April 2023 and continue into 2026. Mortgage interest is deductible in full before the corporation tax calculation.
What is the dividend tax rate for property company profits in 2026/27?
After corporation tax, dividends from a property company attract dividend tax at 8.75% for basic-rate taxpayers, 33.75% for higher-rate taxpayers, and 39.35% for additional-rate taxpayers. The first £500 of dividends per tax year is covered by the dividend allowance and is tax-free. Combining a small PAYE salary with dividend extraction is the standard approach for most property company directors.
Does capital gains tax apply when transferring properties to a company?
Yes. Transferring properties to a connected limited company is a deemed disposal at market value for CGT purposes. Residential property CGT rates are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers (post Autumn 2024 Budget). Section 162 holdover relief can defer the CGT charge on incorporation where the portfolio constitutes a business transferred as a going concern, but qualification criteria are specific and professional advice is essential.
The property portfolio structure decision in 2026 is more consequential than at any point since the Section 24 restriction was introduced. Higher-rate taxpayers building a new portfolio should use a limited company without exception: the Section 24 advantage compounds year on year, and there is no SDLT cost on new purchases made directly by the company. Existing landlords with personal-name portfolios must quantify the one-time SDLT and CGT cost of incorporation against the present value of future tax savings, factoring in their investment horizon and whether partnership incorporation relief is available. The relief can compress the payback from 8 to 10 years to 1 to 2 years, fundamentally changing the decision. In all cases, this decision should be made with a tax-specialist and a CFO who understand both the property finance market and the corporate tax position, not on the basis of generic online guidance.
