More UK landlords now buy through a limited company than at any point before. Mortgage interest rules changed. Personal tax rates climbed. A company structure started to look far more attractive.
This guide walks through the tax benefits, the real costs, and how to decide if incorporation suits your portfolio.
Why Landlords Choose a Limited Company
A limited company is a separate legal entity. It owns the property, not you personally. Profits get taxed under Corporation Tax rules instead of Income Tax.
For higher-rate taxpayers, this shift matters. Companies pay Corporation Tax at 19% on profits up to £50,000, and 25% on profits over £250,000, with a tapered rate in between. Personal Income Tax on rental profit can reach 45%.
Company ownership also protects your personal assets. Because a limited company is a separate legal entity, any liabilities linked to the property fall on the company, not on you as director or shareholder.
Tax Benefits of Buying Property Through a Limited Company
Three tax advantages drive most incorporation decisions.
- Lower tax on profits. Corporation Tax rates sit below higher and additional Income Tax bands.
- Full mortgage interest relief. Companies can still deduct finance costs, including mortgage interest, from rental profits in full, unlike individual landlords.
- Flexible profit extraction. Profit can stay inside the company until you need it, rather than being taxed the year you earn it personally.
These benefits compound as your portfolio grows, which is why incorporation appeals most to landlords planning to scale.
The Real Costs and Disadvantages
Nothing here comes free. A limited company structure carries extra costs that shrink or eliminate the tax gain for some landlords.
Higher Mortgage Costs
Lenders view limited companies as riskier borrowers than individual homeowners because of their reduced personal liability. Expect fewer lender choices and slightly higher rates.
Administrative Burden
Running a limited company means filing accurate accounting records, annual accounts, tax returns, and sometimes holding formal meetings. Most landlords pay an accountant to manage this.
Stamp Duty on Transfers
Incorporating an existing portfolio triggers Stamp Duty Land Tax, calculated on market value regardless of whether cash actually changes hands.
Transferring an Existing Buy-to-Let Into a Limited Company
Moving property you already own into a company counts as a sale in HMRC’s eyes, even between you and your own business.
| Tax | What Happens on Transfer |
| Stamp Duty Land Tax | Charged on the property’s market value, not the price actually paid, even where no money changes hands |
| Capital Gains Tax | Treated as a disposal at market value, so any gain since purchase can trigger a CGT bill |
| Incorporation Relief | Can defer both SDLT and CGT, but HMRC generally expects around 20 hours a week of active property management to qualify |
Because both taxes hit at once, transferring an existing portfolio needs careful modelling before you commit.
Getting a Mortgage as a Limited Company
Company mortgages, often called SPV (Special Purpose Vehicle) mortgages, work differently to personal buy-to-let loans.
Lenders assess the company’s rental income, your personal guarantee, and your track record as a director. Rates run slightly higher than personal buy-to-let deals, and the lender pool is smaller.
Most brokers recommend setting up a company limited by shares, with a SIC code that clearly states property investment as the business activity.
How to Set Up a Limited Company for Property Investment
- Register with Companies House. Choose a name, a registered address, and a property-related SIC code.
- Appoint directors and shareholders. One person can hold both roles.
- Open a business bank account. Keep company and personal finances fully separate.
- Arrange a company mortgage. Speak to a specialist broker who deals with SPV lenders.
- Instruct an accountant. Corporation Tax, VAT thresholds, and annual filings need ongoing management.
Is a Limited Company Right for Your Portfolio?
A limited company structure tends to suit:
- Higher and additional-rate taxpayers
- Landlords planning to grow beyond one or two properties
- Investors who plan to reinvest profit rather than draw it out immediately
- Anyone prioritising limited liability protection
Basic-rate taxpayers with a single investment property often find direct personal ownership simpler and cheaper overall. Portfolio size and your personal tax rate decide which route wins.
Frequently Asked Questions
Is it worth buying property through a limited company?
It depends on your tax rate and portfolio size. Higher-rate taxpayers and landlords planning multiple properties usually benefit most from limited company property investment, thanks to lower Corporation Tax rates and full mortgage interest relief. Basic-rate taxpayers with one property often find personal ownership simpler and cheaper.
What are the tax benefits of buying property through a limited company?
A limited company pays Corporation Tax on rental profit instead of Income Tax, and rates sit lower than higher personal tax bands. Companies also deduct full mortgage interest from profits, and can retain earnings inside the business rather than paying personal tax immediately on every pound earned.
Can I transfer my buy-to-let property into a limited company?
Yes, but HMRC treats the move as a sale at market value. This can trigger Stamp Duty Land Tax and Capital Gains Tax at the same time, even though the same person effectively still owns the asset. Model both costs carefully before transferring an existing limited company portfolio.
Do I pay stamp duty when transferring property to a limited company?
Usually, yes. Stamp Duty Land Tax applies to the property’s market value on transfer, regardless of the price paid or whether cash changes hands at all. Larger portfolios can face substantial SDLT bills, making professional advice essential before any limited company transfer.
How much corporation tax do I pay on rental income?
Companies pay 19% Corporation Tax on profits up to £50,000, rising to 25% on profits above £250,000, with a tapered rate between the two thresholds. This structure often beats personal Income Tax rates for higher earners running limited company property investment.
What are the disadvantages of buying property through a limited company?
Limited companies face higher mortgage rates, a smaller pool of lenders, and ongoing administrative costs like annual accounts and Corporation Tax filings. Stamp duty on transfers and less favourable lending terms can offset tax savings for smaller, lower-rate landlords.
Can I get a mortgage as a limited company?
Yes, through specialist SPV (Special Purpose Vehicle) mortgage products designed for limited company property investment. Lenders assess the company’s projected rental income alongside a personal guarantee from directors. Expect slightly higher rates and fewer lender options than standard personal buy-to-let mortgages.
Do I pay Capital Gains Tax when transferring property into a company?
Generally, yes. HMRC treats the transfer as a disposal at market value, so any increase in the property’s value since purchase can create a Capital Gains Tax bill. Incorporation Relief may defer this for active property businesses meeting strict HMRC conditions.
