However, following significant tax changes in recent years, many landlords are now choosing to purchase and hold rental property via a limited company rather than in their personal name.
This guide explains the advantages of buy to let via a limited company, who it is best suited for, and what you need to consider before deciding if this structure is right for your property investment strategy.
What Is a Buy-to-Let Limited Company?
A buy-to-let limited company is a UK-registered company created specifically to purchase, hold, and manage rental properties. Instead of owning the property personally, the company becomes the legal owner, and you operate as a director and shareholder.
This structure provides both tax efficiency and financial separation, making it particularly attractive for portfolio landlords and higher-rate taxpayers.
Key Features of a Buy-to-Let Limited Company
• Separate legal entity from you personally
• Limited liability protection
• Corporation tax applied to profits
• Ability to deduct mortgage interest in full
By operating through a company, investors gain more control over how profits are retained, reinvested, or distributed.
Tax Benefits of Buy to Let via a Limited Company
One of the main reasons landlords incorporate is tax efficiency. Since the introduction of Section 24, personal landlords can no longer fully deduct mortgage interest from rental income. Limited companies, however, are not affected by this restriction.
Key Tax Advantages
• Lower tax on profits: Corporation tax is typically lower than higher-rate income tax
• Full mortgage interest relief: Interest is treated as a business expense
• Flexible profit extraction: Directors can choose when and how to take income
• Efficient reinvestment: Profits can be retained to grow the portfolio
For investors planning to expand, retaining profits within a company can significantly accelerate portfolio growth.
Important note: Tax rules are complex and subject to change. Professional tax advice should always be sought before incorporating.

Strategic Investment Benefits
Using a limited company is not just about tax. It is also a powerful long-term investment structure.
Why Investors Choose a Limited Company
• Asset protection: Personal assets are separated from business risk
• Portfolio scalability: Easier to grow beyond one or two properties
• Succession planning: Shares can be transferred more efficiently than property
• Professional credibility: Seen favourably by lenders and partners
For serious investors with growth ambitions, a limited company offers structure, flexibility, and control.
Limited Company Buy-to-Let Mortgages Explained
Limited company buy-to-let mortgages differ from personal mortgages. While the application process can be more involved, they offer important advantages.
What to Expect
• Slightly higher interest rates than personal buy-to-let mortgages
• Personal guarantees usually required from directors
• Lender assessment focuses on rental coverage rather than personal income
Why They Still Make Sense
• Mortgage interest is fully deductible
• More lenders now actively support limited company structures
• Suitable for HMOs, multi-unit blocks, and portfolio expansion
When structured correctly, the tax savings often outweigh the increased mortgage costs.
Setting Up and Running a Buy-to-Let Limited Company
Setting up a limited company involves more administration than personal ownership, but the process can be straightforward with professional support.

Is a Limited Company Right for You?

Frequently Asked Questions
• Is buy to let via a limited company more tax efficient?
• In many cases, yes—particularly for higher-rate taxpayers due to full mortgage interest relief and lower corporation tax rates.
• Can I transfer existing properties into a limited company?
• Yes, but this may trigger stamp duty and capital gains tax, so professional advice is critical.
• Do limited company landlords pay less tax overall?
• Not always. Tax efficiency depends on how profits are used, personal income levels, and long-term goals.
Conclusion: Maximising Buy-to-Let Returns with a Limited Company
Choosing to invest in buy-to-let property through a limited company can provide significant tax advantages, improved risk management, and long-term strategic flexibility.
While the structure involves additional responsibilities, for the right investor the benefits can far outweigh the complexity. With careful planning and professional guidance, a limited company can be a powerful vehicle for building a resilient and profitable property portfolio.
