Limited Company vs Personal Name for Buy-to-Let: Complete Tax Guide

For UK property investors and buy-to-let (BTL) landlords, deciding whether to purchase residential rental property in your personal name or through a Special Purpose Vehicle (SPV) Limited Company is one of the most critical financial decisions you will ever make. Since the phased implementation of Section 24 under the Finance Act 2015 and Income Tax (Trading and Other Income) Act 2005 (ITTOIA 2005 s.272A), individual landlords can no longer deduct mortgage interest as a business revenue expense. This single legislative change has completely reshaped landlord profitability across England, Scotland, Wales, and Northern Ireland.

Holding property through an SPV limited company allows 100% of mortgage interest and finance costs to remain fully deductible against Corporation Tax (19% to 25%). However, operating through a limited company introduces commercial mortgage premiums, higher arrangement fees, strict accounting compliance, and a secondary tax layer when extracting profits as dividends. This comprehensive, HMRC-audited guide breaks down every statutory nuance, mathematical formula, stamp duty surcharge, capital gains rule, and profit extraction strategy for the 2026/27 tax year.

Executive Summary: Master Tax Comparison Matrix (2026/27)

The table below provides a statutory side-by-side comparison of direct personal property ownership versus corporate SPV ownership under 2026/27 UK tax legislation:

Chapter 1: The Section 24 Trap – The Mathematical Reality for Personal Landlords

Prior to April 2017, UK landlords were taxed on their genuine net commercial profit: gross rental income minus all allowable expenses, including 100% of mortgage interest. Under Section 24 of the Finance (No. 2) Act 2015 (codified under ITTOIA 2005 s.272A), mortgage interest and other finance costs (such as mortgage arrangement fees and broker fees) are no longer deductible from property income for individual landlords.

Instead, individual landlords are taxed on their gross rental income minus non-finance allowable expenses (e.g., insurance, letting agent fees, safety certificates, repairs). After calculating your tax liability across all income sources, HMRC grants a Basic Rate Tax Reduction equal to 20% of the finance costs.

“Section 24 disconnects tax liability from actual cash flow. A landlord can be making zero cash profit or even experiencing negative cash flow after paying the bank, yet still receive a massive tax bill from HMRC.”

David Vance, CTA FCA

The Section 24 Calculation Formula:

1. Calculate Taxable Property Turnover: Gross Rental Income − Allowable Property Expenses (excluding finance costs).
2. Stack onto Other Income: Add this taxable turnover directly to your employment, pension, or self-employed earnings.
3. Calculate Gross Income Tax: Apply the 20% Basic, 40% Higher, or 45% Additional rate bands to your total combined income.
4. Apply Section 24 Tax Credit: Deduct a tax credit equal to 20% of the lowest of:
   • Total finance costs incurred in the year.
   • Net property profits from the property business.
   • Total adjusted income exceeding the Personal Allowance.

The “Phantom Income” & Personal Allowance Taper Trap

The most dangerous side effect of Section 24 is that adding gross rental turnover artificially inflates your Adjusted Net Income (ANI). This causes severe secondary tax consequences:

• Pushing Basic Rate Earners into the 40% Band: If your salary is £42,000 and your gross rental profit before interest is £15,000, your total ANI becomes £57,000. This pushes you over the £50,270 higher rate threshold, converting you into a higher rate taxpayer.
• High Income Child Benefit Charge (HICBC): If your inflated ANI exceeds £60,000, you begin losing Child Benefit via the HICBC taper (fully wiped out at £80,000).
• The 60% Personal Allowance Taper Trap: If your ANI is pushed between £100,000 and £125,140, you lose £1 of your £12,570 tax-free Personal Allowance for every £2 of income, creating a brutal effective marginal tax rate of 60% on rental profit!
• Loss of Marriage Allowance & Tax-Free Savings Band: Crossing into the higher rate band immediately forfeits the Marriage Allowance transfer (£252/yr) and cuts your Personal Savings Allowance from £1,000 to £500.

Chapter 2: Corporation Tax for Property SPVs (2026/27 Rates & Rules)

A Special Purpose Vehicle (SPV) limited company is a standard private company registered at Companies House with specific Standard Industrial Classification (SIC) codes for property letting (e.g., 68100 Buying and selling of own real estate, 68209 Other letting and operating of own or leased real estate). Lenders require SPVs to isolate property investment risk from active trading businesses.

Limited companies are completely exempt from Section 24. Under the Corporation Tax Act 2009 (Loan Relationships regime), 100% of mortgage interest, commercial finance fees, and loan arrangement costs are treated as fully allowable revenue expenses deducted prior to calculating taxable company profits.

Important – The Associated Companies Rule (CTA 2010 s.18E): If you control multiple limited companies (for example, a trading consulting business and two separate property SPVs), the £50,000 and £250,000 profit thresholds are divided equally among the total number of associated companies. If you own 3 companies, the 19% small profits threshold drops to £16,667 per company.

Chapter 3: Stamp Duty Land Tax (SDLT) & The 5% Additional Surcharge

When buying residential property in England or Northern Ireland, both individuals purchasing an additional property and limited companies purchasing any dwelling are subject to the Higher Rates for Additional Dwellings (HRAD) under Finance Act 2003 Schedule 4ZA.

The HRAD surcharge is fixed at 5.0% above standard residential SDLT rates across all purchase price tiers for 2026/27:

Devolved Tax Variations: In Scotland, Land and Buildings Transaction Tax (LBTT) applies an Additional Dwelling Supplement (ADS) of 6.0%. In Wales, Land Transaction Tax (LTT) applies Higher Residential Rates starting at 4.0% for the lowest tier.

Annual Tax on Enveloped Dwellings (ATED): If your limited company acquires a single residential property valued at over £500,000, it falls within the scope of ATED. However, as long as the property is let to third-party commercial tenants on an arm’s-length basis, your company can claim 100% ATED Relief (Finance Act 2013 s.133) by submitting an annual relief return to HMRC by 30 April each year.

Chapter 4: Capital Gains on Exit – Personal CGT vs Corporate Sale

When selling an investment property that has appreciated in capital value, the tax treatment diverges sharply between personal and corporate ownership:

1. Personal Ownership: Residential Capital Gains Tax (18% / 24%)

• Annual Exempt Amount (AEA): £3,000 per individual (£6,000 for married couples/civil partners owning 50/50).
• Tax Rates: 18% on net gains falling within the unused basic rate band; 24% on all gains falling in higher/additional rate bands.
• Strict 60-Day Reporting: Under FA 2019 Schedule 2, UK residents disposing of residential property must report the gain and pay the estimated CGT to HMRC within 60 days of completion via the online Capital Gains Tax on UK Property account.
• Direct Cash Access: Once the 18%/24% CGT is settled with HMRC, 100% of the remaining capital is personal cash that you can spend immediately with zero further tax.

2. Limited Company Ownership: Corporation Tax on Capital Gains

• No Annual Exempt Amount: Limited companies do not receive the £3,000 CGT allowance.
• Tax Rates: The chargeable capital gain is added to company profits and taxed at standard Corporation Tax rates: 19% (under £50k) to 25% (over £250k).
• Frozen Indexation: Indexation allowance for companies was permanently frozen in December 2017, meaning inflation relief is no longer available on subsequent growth.
• The “Double Tax” Extraction Hurdle: After the company pays 19%–25% Corporation Tax, the sales proceeds remain inside the corporate bank account. If you withdraw the funds personally, you face income tax on dividends (up to 39.35%) or must conduct a formal Members’ Voluntary Liquidation (MVL).

Chapter 5: Profit Extraction Strategies – How to Get Cash Out of an SPV

One of the biggest misunderstandings among new landlords is assuming that company profit is personal spending money. Money inside an SPV belongs to the legal entity. To move money into your personal bank account, you must use one of four primary extraction routes:

1. Director’s Loan Account (DLA) Capital Drawdown – 100% Tax-Free

When you purchase a property inside an SPV, you typically inject personal savings to fund the deposit (e.g., £60,000), stamp duty (e.g., £12,500), and legal fees. In corporate accounting, this money is recorded as a Director’s Loan to the Company.

As the property generates net rental income, the company can repay this initial £72,500 director’s loan to you completely tax-free. There is 0% Income Tax, 0% National Insurance, and 0% Dividend Tax on loan repayments until the full balance is cleared.

2. Dividend Distributions (2026/27 Rates)

Once the Director’s Loan Account is fully repaid, retained profits can be distributed to shareholders as dividends from post-Corporation Tax earnings:

• Tax-Free Dividend Allowance: £500 per individual per tax year.
• Basic Rate Dividend Tax: 8.75% on dividends within the basic rate band (up to £50,270).
• Higher Rate Dividend Tax: 33.75% on dividends between £50,271 and £125,140.
• Additional Rate Dividend Tax: 39.35% on dividends exceeding £125,140.

3. Employer Pension Contributions – Ultimate Tax Efficiency

Under UK tax rules, a property SPV can make direct employer pension contributions into the director’s personal pension or SIPP. These contributions are treated as an allowable business expense, reducing company profits and saving 19% to 25% Corporation Tax, while incurring zero personal income tax or National Insurance for the director (subject to the £60,000 Annual Pension Allowance).

Chapter 6: Transferring Existing Personal Property into an SPV (Section 162 Relief)

If you already own rental properties in your personal name, transferring them into a newly formed limited company is treated legally as a connected party disposal at open market value. This triggers two immediate tax hurdles:

1. Personal Capital Gains Tax (18%/24%): Taxed on the capital gain between your historical purchase price and today’s market value.
2. Stamp Duty Land Tax (SDLT + 5% Surcharge): The company must pay full SDLT at the 5% additional residential rate on current market value.

Section 162 Incorporation Relief (TCGA 1992 s.162)

Under Section 162, individual landlords can defer the entire Capital Gains Tax liability by transferring a property rental “business as a going concern” in exchange for shares in the limited company. The latent capital gain is rolled over into the base cost of the company shares.

The Ramsay v HMRC [2013] UKUT 226 (TCC) Test: To qualify for Section 162, you cannot simply be a passive property owner with a letting agent. You must prove to HMRC that the portfolio operates as a genuine commercial business. In the landmark Ramsay case, the Upper Tribunal established that dedicating at least 20 hours per week to active property management (finding tenants, handling repairs, collecting rent, managing compliance) was sufficient to constitute a business.

SDLT Partnership Relief (FA 2003 Schedule 15): If the properties have been run as a legitimate property partnership with a joint partnership agreement and HMRC partnership tax returns (SA800) for a minimum qualifying period (often recommended 12–24 months), the transfer to an SPV can qualify for the Sum of Lower Proportions (SLOP) formula, reducing SDLT on the transfer to £0.

Chapter 7: 4 Worked Mathematical Scenarios (2026/27 Tax Year)

To illustrate the exact cash flow and tax differences in practice, let us examine four realistic landlord scenarios under 2026/27 legislation:

Scenario 1: Higher-Rate Professional Buying a Single Buy-to-Let

Sarah earns £70,000 in salary (40% Higher Rate band). She purchases a BTL property for £250,000 generating £15,000 gross annual rent. She has £8,000 in mortgage interest (75% LTV at 4.27%) and £2,000 in allowable maintenance/insurance costs. Her actual pre-tax cash profit is £5,000.

• Personal Name (Section 24):
  • Taxable Property Profit: £15,000 − £2,000 = £13,000.
  • Higher Rate Tax (40%): 40% × £13,000 = £5,200.
  • Section 24 Tax Credit: 20% × £8,000 finance costs = −£1,600.
  • Net Tax Payable to HMRC: £5,200 − £1,600 = £3,600.
  • Net Cash in Sarah’s Pocket: £5,000 cash profit − £3,600 tax = £1,400.
  • Effective Tax Rate on Cash Profit: £3,600 ÷ £5,000 = 72.0%!
• Limited Company SPV:
  • Taxable Corporate Profit: £15,000 − £8,000 − £2,000 = £5,000.
  • Corporation Tax (19% Small Profits Rate): 19% × £5,000 = £950.
  • Net Profit Retained in Company: £5,000 − £950 = £4,050.
  • Effective Tax Rate: 19.0%.
  • Annual Tax Advantage: £2,650 per year saved inside the SPV!

Scenario 2: High-Leverage Multi-Property Portfolio (The Phantom Profit Squeeze)

Mark owns a portfolio generating £60,000 gross rental income, with £36,000 in mortgage interest and £8,000 in operating costs. His actual pre-tax cash profit is £16,000 (£60,000 − £36,000 − £8,000). Mark has other employment income placing him in the 40% higher rate bracket.

Key Takeaway: Personally, Mark loses 85.0% of his net cash profit in tax (£13,600 tax on £16,000 profit). If mortgage rates were slightly higher and interest reached £42,000, Mark would face a tax bill of £12,400 on a cash profit of £10,000, causing a cash loss of -£2,400 despite a profitable rental yield!

Scenario 3: Portfolio Reinvestment vs Personal Extraction (5-Year Horizon)

An investor acquiring 4 properties over 5 years retaining all rental profits to compound deposits:

• In Personal Name: With 40% income tax and Section 24 clawbacks eating over 70% of cash flow, accumulating the next £60,000 deposit takes 8.5 years.
• In Limited Company SPV: Tax is capped at 19%, allowing 81% of net rental profit to pool inside the company. The next £60,000 deposit is accumulated in just 3.2 years, accelerating portfolio expansion by 2.6×.

Scenario 4: Section 162 Incorporation of a £1.2M Portfolio

David owns 4 properties worth £1,200,000 purchased historically for £800,000 (£400,000 latent capital gain), with £700,000 outstanding mortgages. Net equity is £500,000.

• Standard Transfer (No Relief): Triggers £95,280 in personal CGT (24% on £397,000 gain) plus £86,500 in SDLT (including 5% HRAD) = £181,780 upfront cash tax cost.
• Section 162 + Partnership Transfer: David demonstrates 22 hours/week of active management (meeting Ramsay criteria) and formal partnership status. The £400,000 capital gain is rolled over into the base cost of newly issued ordinary shares, and SDLT is eliminated under Schedule 15. Upfront cash tax = £0.

Chapter 8: The Definitive Decision Framework – Which Structure Is Right for You?

Frequently Asked Questions (AEO & GEO Reference)

Q1: What is Section 24 and why does it penalize personal landlords?
A: Section 24 (ITTOIA 2005 s.272A) removes mortgage interest as a deductible revenue expense for individual landlords. Instead of being taxed on net profit, personal landlords are taxed on gross rental turnover minus operational costs, receiving only a flat 20% basic rate tax credit on mortgage interest. For higher-rate (40%) and additional-rate (45%) taxpayers, this creates an effective tax rate often exceeding 70% to 100%+ of actual net cash profit.

Q2: Can a limited company deduct 100% of mortgage interest in 2026/27?
A: Yes. Limited companies (SPVs) are completely exempt from Section 24. Under the Corporation Tax Act 2009 Loan Relationships rules, 100% of mortgage interest, commercial arrangement fees, and loan finance costs are fully deductible as allowable business expenses before Corporation Tax is calculated.

Q3: Are mortgage interest rates higher for limited companies?
A: Yes. SPV limited company mortgages typically carry interest rates 0.75% to 1.50% higher than personal buy-to-let mortgages. In addition, commercial lender arrangement fees are frequently percentage-based (1.5% to 3.0% of the loan) rather than fixed fees. Higher borrowing costs must be weighed against Section 24 income tax savings.

Q4: What Corporation Tax rate does a property company pay in 2026/27?
A: Property SPVs pay 19% Corporation Tax on net annual profits up to £50,000 (Small Profits Rate). Profits between £50,000 and £250,000 are subject to Marginal Relief (effective 26.5% rate on the slice), and profits over £250,000 pay the Main Rate of 25%. Under CTA 2010 s.18E, these profit thresholds are shared equally if you control multiple associated companies.

Q5: Can I withdraw cash from my property company tax-free?
A: Yes, by drawing down against your Director’s Loan Account (DLA). Any personal cash you introduced into the company to fund property deposits, stamp duty, or refurbishment is recorded as a loan to the company. The SPV can repay this loan to you completely tax-free with 0% Income Tax, 0% Dividend Tax, and 0% National Insurance.

Q6: How are dividends from a property company taxed in 2026/27?
A: Once the DLA is repaid, profits distributed as dividends are taxed at personal dividend rates after a £500 tax-free dividend allowance: 8.75% (basic rate band), 33.75% (higher rate band), and 39.35% (additional rate band over £125,140).

Q7: Do limited companies pay the 5% Stamp Duty surcharge?
A: Yes. Under Finance Act 2003 Schedule 4ZA, all residential property purchases by a corporate entity are subject to the 5.0% Higher Rates for Additional Dwellings (HRAD) surcharge, starting from £0 of the purchase price (e.g., 5% on the first £250,000, 10% on £250k–£925k).

Q8: What happens when a limited company sells a property?
A: The company pays 19% to 25% Corporation Tax on the net capital gain. Unlike individuals, companies do not receive an annual tax-free CGT allowance (£3,000). Once the company pays Corporation Tax, the remaining cash stays inside the company; taking the cash out personally requires dividend tax or formal company liquidation.

Q9: Can I transfer properties I already own into a company tax-free?
A: Only if you qualify for statutory reliefs. Otherwise, transferring property triggers personal Capital Gains Tax (up to 24%) and corporate SDLT (including the 5% surcharge). To defer CGT, you must qualify for Section 162 Incorporation Relief by proving you operate a genuine property business under the Ramsay [2013] 20-hour rule, and use Schedule 15 Partnership rules to mitigate SDLT.

Q10: What is the Ramsay test for Section 162 Incorporation Relief?
A: In Ramsay v HMRC [2013] UKUT 226 (TCC), the Upper Tribunal ruled that property investment constitutes a “business” for Section 162 relief if the owner spends substantial time (typically 20+ hours per week) actively managing the properties, maintaining tenancies, and conducting day-to-day operations rather than being a passive investor.

Q11: Is a limited company better for Inheritance Tax (IHT)?
A: Yes. Corporate ownership offers significant estate planning flexibility. You can issue different classes of shares (Alphabet shares or Growth shares) to children or grandchildren, gifting future capital growth out of your estate while retaining full voting control and dividend rights during your lifetime.

Q12: At what point does a limited company become more tax-efficient?
A: A limited company is almost always more tax-efficient for individuals earning over £50,270 (Higher and Additional Rate taxpayers) purchasing properties with mortgages (gearing >50%). For basic-rate taxpayers with unencumbered properties who need 100% of rental income for living expenses, personal ownership remains more cost-effective due to lower mortgage and accounting fees.
