Buying buy to let property through a limited company is now mainstream in the UK. It can be tax efficient for some landlords, especially where borrowing is significant and profits are being reinvested. It can also be expensive and administratively heavier than owning personally.
This guide explains how it works, what HMRC taxes apply, the mortgage reality, and a simple decision framework so you can decide whether a limited company is right for your buy to let strategy.
What it means to buy to let through a limited company
Buy to let property through a limited company means the company is the legal owner of the property. The company receives the rent, pays the expenses, and is taxed on the profits. You typically own shares in the company and act as a director.
Most landlords use a special purpose vehicle company, commonly called an SPV. This is usually a UK limited company set up solely to hold rental property, with a property letting SIC code and no trading history. Many mortgage lenders prefer SPVs because the structure is simple and accounts are easier to assess.
Why landlords use a company structure
Landlords usually consider a limited company for four core reasons.
Mortgage interest treatment
Companies can generally deduct mortgage interest as a business expense when calculating taxable profit. This is a key difference compared to personal ownership of residential buy to let property.
Potentially lower headline tax rate
Profits inside a company are subject to Corporation Tax rather than Income Tax. This can be attractive for higher rate and additional rate taxpayers.
Reinvestment and portfolio growth
If profits are retained inside the company rather than withdrawn, they can be reinvested into future property purchases more efficiently.
Estate and succession planning flexibility
Shares in a company can sometimes be transferred or structured more flexibly than direct property ownership, although this requires professional advice.
The downside is that taking money out of the company personally can create a second layer of tax. This is why company ownership often suits landlords who reinvest rather than rely on rental income for living costs.
Tax basics, company vs personal ownership
Corporation Tax on rental profits
A limited company pays Corporation Tax on its rental profits after allowable expenses. Mortgage interest is usually treated as an allowable expense for companies, which can significantly improve post tax cash flow compared to personal ownership.
Personal tax when you take money out
Company profits belong to the company. If you want to use the money personally, it is usually extracted as dividends or salary, which may trigger personal tax. Many comparisons fail because they ignore this second layer of tax.
A limited company can be very efficient for retained profit, but less efficient if most profits are withdrawn each year.
Capital Gains Tax vs company tax on sale
Personally owned properties are taxed under Capital Gains Tax rules when sold. When a company sells a property, the gain is taxed within the company under Corporation Tax rules. Further tax may apply if the proceeds are later extracted.
The better option depends on how long you plan to hold the property and what you intend to do with the sale proceeds.
Moving existing properties into a limited company
Transferring personally owned buy to let property into a company is not a simple paper exercise. In many cases it can trigger Capital Gains Tax and Stamp Duty Land Tax based on market value.
There is a relief known as Incorporation Relief that can defer Capital Gains Tax where a genuine property business is transferred to a company in exchange for shares. Eligibility depends on the specific facts, and HMRC scrutiny in this area is high.
Practical takeaway
Company ownership is often most attractive where you are a higher rate taxpayer, have significant mortgage interest, and plan to reinvest profits rather than withdraw them.
Stamp duty and other purchase costs
Buying through a limited company does not avoid Stamp Duty Land Tax. In most cases, a company buying residential property will pay the higher rates that apply to additional dwellings.
Companies may also be subject to specific corporate Stamp Duty rules in certain circumstances, particularly for high value residential property.
Other costs to budget for include company formation, legal fees, mortgage arrangement fees, accounting costs, and ongoing compliance expenses
Limited company buy to let mortgages, what to expect
Limited company buy to let mortgages are assessed differently to personal mortgages.
Lenders usually focus first on the rental income of the property, then assess director experience and financial background. Personal guarantees from directors are common.
Key points to expect.
- Rates and fees can be higher than personal buy to let mortgages
- SPV companies are generally preferred by lenders
- Personal guarantees are commonly required
- Portfolio landlords face more detailed underwriting
Mortgage criteria change regularly, so current advice is essential before committing.
How to set up and buy through a property company
Define your strategy
Decide how many properties you want, how much you plan to borrow, and whether profits are for reinvestment or personal income.
Form the company
Usually a UK limited company set up as an SPV with property letting as its core activity.
Open a business bank account
All rental income and expenses should flow through the company account.
Set the shareholder and director structure
This affects control, dividends, and long term planning.
Speak to a mortgage broker early
Confirm lender appetite before making offers.
Run a tax forecast
Compare personal ownership and company ownership over several years.
Complete the purchase
The company buys the property, and all legal and insurance arrangements are in the company name.
Ongoing running costs and compliance
Owning property through a limited company comes with additional responsibilities.
- Annual company accounts and Corporation Tax returns
- Companies House confirmation statements and filing deadlines
- Bookkeeping and record keeping obligations
- Director legal duties and responsibilities
These costs are manageable but should be factored into your decision from the start.
When a limited company usually makes sense

- You are a higher rate or additional rate taxpayer
- You use meaningful borrowing
- You plan to reinvest profits rather than withdraw them
- You want a structured approach to portfolio growth or succession planning
It may be less suitable if you are a basic rate taxpayer, have little mortgage interest, or rely on rental income for personal living expenses.
Common mistakes to avoid
- Comparing only headline tax rates
- Ignoring Stamp Duty and incorporation taxes
- Using the wrong company structure for lenders
- Poor record keeping
- Mixing personal and company finances
