When investing in buy-to-let property in the UK, one of the key decisions is whether to purchase in your own name or through a limited company. This choice affects tax efficiency, profitability, and your ability to grow your property portfolio.
In this blog, we'll explore the differences between personal ownership and limited company ownership, focusing on tax efficiency in 2026. We’ll outline the pros and cons of each option to help you make an informed decision for your investment strategy. Let’s dive into the impact of tax efficiency on property ownership and find the best structure for you in 2026.
Personal vs Ltd Company Buy-to-Let: What's the Difference?
There are two main ways to own and operate a buy-to-let property in the UK: personal ownership and limited company ownership.
Why Is Tax Efficiency Important for Buy-to-Let Investors?
Tax efficiency plays a crucial role in buy-to-let property investment. How much tax you pay on rental income, mortgage interest, capital gains, and inheritance can significantly impact your profitability. A tax-efficient strategy ensures that you are keeping as much of your rental income as possible and reinvesting it into growing your property portfolio.
In recent years, UK tax law has evolved, making it essential for property investors to carefully consider the most efficient structure for their rental business. The changes to mortgage interest relief under Section 24 and the differences in corporation tax rates versus income tax have reshaped the landscape for landlords.
For landlords with large portfolios or those operating at higher tax bands, making the right decision about how to structure their business is critical.
How Does Personal Name Ownership Affect Taxation in 2026?
Owning a buy-to-let property in your personal name comes with several tax implications. These include paying income tax on rental profits, the restricted mortgage interest relief under Section 24, and paying capital gains tax when you sell.
Rental Income Tax
Rental income is taxed as part of your overall income, which means it is subject to the Income Tax rates applicable to your total income for the tax year. The current income tax bands for the UK are:
- Personal Allowance (0%) - First £12,570.
- Basic Rate (20%) - On taxable income between £12,571 and £50,270.
- Higher Rate (40%) - On taxable income between £50,271 and £125,140.
- Additional Rate (45%) - On taxable income over £125,140.
Section 24 – Restricted Mortgage Interest Relief
The introduction of Section 24 in the 2015 Finance Act dramatically changed how mortgage interest is treated for tax purposes. Previously, landlords could deduct mortgage interest from their rental income before calculating the amount of tax they owed. However, Section 24 phased out this relief and replaced it with a basic-rate tax credit on mortgage interest. This means that regardless of whether you are a basic, higher, or additional-rate taxpayer, you can only claim a tax credit of 20% on your mortgage interest payments.
For example,
If you have £10,000 of mortgage interest on a buy-to-let property and £30,000 in rental income, you used to be able to deduct the full £10,000 from your rental income, meaning you’d be taxed on only £20,000. However, under Section 24, the tax credit is capped at 20%, and the full £30,000 rental income is taxed as if you had no mortgage interest, which increases your overall tax liability.
Capital Gains Tax (CGT)
When you sell a buy-to-let property that you own personally, Capital Gains Tax is applied to any profit you make. For residential property, the current CGT rate for higher-rate taxpayers is 24%, which is higher than the CGT rate for other assets. This is an important consideration when deciding whether to sell or transfer properties.
What Are the Tax Benefits of Owning Buy-to-Let Properties in a Limited Company?
For many landlords, owning properties through a limited company offers substantial tax advantages, especially if they are in higher tax brackets or plan to scale their portfolio. Below are some of the main tax benefits.
Corporation Tax vs Income Tax
Limited companies pay corporation tax on their profits, which is generally lower than personal income tax rates. The current corporation tax rate is 19% for profits up to £50,000, and 25% for profits over £250,000 starting in April 2023. In contrast, personal income tax rates range from 20% to 45%, depending on your income. Therefore, if you're a higher-rate taxpayer (40% or 45%), a limited company structure could result in significant tax savings. For example, with £20,000 in rental income, the tax in a personal ownership structure could reach 45%, but in a company, it would only be 19%.
Full Mortgage Interest Deduction
One of the main advantages of limited company ownership is the ability to fully deduct mortgage interest from rental income. Under Section 24 for personal ownership, landlords can only claim a 20% tax credit on mortgage interest. However, for limited companies, mortgage interest is treated as a business expense, meaning it can be fully deducted before paying corporation tax on profits. This is a significant benefit for landlords with high mortgage interest.
Reinvesting Profits
Limited companies also offer the ability to retain profits within the company, which can be reinvested in acquiring new properties or improving existing ones. These profits are not subject to personal tax until withdrawn as dividends or salary, providing flexibility to scale your portfolio faster.
Inheritance Tax Planning
Limited companies offer greater inheritance tax (IHT) planning flexibility. By holding properties as company shares, you can transfer shares to family members, potentially reducing IHT liabilities. In personal ownership, properties are part of your estate and may be subject to IHT. Proper planning is essential, so consulting a tax specialist is advisable to ensure the most tax-efficient structure for your estate.
Are There Disadvantages of Limited Company Buy-to-Let Ownership?
While the limited company structure offers numerous benefits, there are some disadvantages to consider.
Higher Mortgage Rates
Mortgages for limited companies usually come with higher interest rates compared to personal buy-to-let loans, as lending to a company is perceived as riskier. The difference can be up to 1% higher, which might outweigh tax savings for investors with smaller portfolios.
Administrative Costs
Running a limited company involves additional administrative tasks, such as filing annual accounts, paying professional fees for accountants and legal services, and covering company registration costs. While these costs can add up, they are often justified for landlords with larger portfolios, as the tax advantages tend to outweigh these expenses.
Dividend Tax
Taking profits from the company is usually done through dividends, which are subject to tax. For the 2025/26 tax year, the dividend tax rates are:
- £0 to £500: 0%
- Income within the basic rate band(after personal allowance): 8.75%
- Income with higher rate band: 33.75%
- Income with the additional rate band: 39.35%
While corporation tax rates are lower, dividend tax may add an extra cost depending on how much you withdraw.
Which Ownership Structure Is More Tax Efficient for Different Landlords?
If you earn less than £50,270 annually, personal ownership is often more tax-efficient. The tax benefits of limited company ownership might not outweigh the additional costs of running a company. In addition, the Section 24 changes have a much smaller impact for basic-rate taxpayers, as they still receive the 20% tax credit on mortgage interest.
What Are the Costs & Process of Switching from Personal to Limited Company Ownership?
Switching from personal ownership to a limited company involves several steps and costs:
- Stamp Duty - When you transfer property to a company, Stamp Duty Land Tax is applied to the value of the property, including the additional 5% surcharge for second homes.
- Capital Gains Tax - The transfer is treated as a sale for tax purposes, which could trigger Capital Gains Tax (CGT) on any profit made from the sale.
Note
You will also need to remortgage the property in the name of the company. This process can be costly and complicated, especially if you have existing mortgages that need to be transferred or refinanced.
Conclusion
The choice between personal ownership and limited company ownership is a key decision for buy-to-let investors. Personal ownership remains a good option for basic-rate taxpayers or those with a small portfolio. However, limited companies offer substantial tax advantages, especially for higher-rate taxpayers or portfolio landlords who are looking to grow their investment.
In 2026, a limited company can help you reduce your tax burden by allowing you to deduct mortgage interest in full and benefit from a lower corporation tax rate. However, there are additional costs and administrative responsibilities, so it’s important to weigh the pros and cons based on your individual circumstances.
As always, it’s advisable to consult with an accountant or tax adviser to determine the most tax-efficient strategy for your property investments.
