Moving buy to let property into a limited company can be highly tax efficient for some landlords, but it is a complex transaction that needs careful planning and solid numbers before you act.
What does incorporating buy to let into a company mean
Incorporation means your existing personally owned rental property is transferred into a limited company which then becomes the legal owner and receives the rent. HMRC treats this as a sale at market value from you to your company, even though you control both, so all the usual tax and legal consequences of a sale apply.
For most landlords the company will be a special purpose vehicle set up solely to own and let property rather than a trading business with other activities. Lenders generally prefer this simple structure when offering company buy to let mortgages, which is why many landlords create a dedicated property company rather than using an existing trading company.
Why landlords consider a company structure
The most common driver is tax efficiency for landlords whose rents push them into the higher and additional income tax bands. An individual pays income tax on rental profits and, due to Section 24 restrictions, can no longer deduct full mortgage interest, instead receiving only a basic rate credit on those finance costs.
A company pays corporation tax on its rental profits, currently nineteen percent on profits up to fifty thousand pounds and twenty five percent on profits above two hundred and fifty thousand pounds, and is still able to deduct mortgage interest in full as a business expense. For highly geared portfolios held by higher rate taxpayers this combination often produces meaningfully higher after tax profits that can be reinvested into more properties.
Limited companies also offer limited liability and can make succession planning more flexible because you can gift or sell shares rather than the property itself. In some cases share transfers can help manage inheritance tax exposure more efficiently than passing on personally owned property.
Key tax implications of incorporation
Capital Gains Tax
When you sell your property to the company HMRC treats this as a disposal at market value, so you may pay Capital Gains Tax on the increase in value since purchase.
Basic rate taxpayers currently pay eighteen percent on gains above the annual allowance, while higher and additional rate taxpayers pay twenty four percent on residential gains.
Where your letting activity is a genuine business rather than a passive investment you may be able to claim incorporation relief, deferring the gain into the value of your shares instead of paying CGT immediately.
From 6 April 2026 this relief must be claimed through your self assessment return rather than being applied automatically, so detailed evidence and advice are vital.
Stamp Duty Land Tax
The company is treated as buying the property at market value, so Stamp Duty Land Tax is due on that value including the surcharge that applies to additional residential properties.
Current rules mean company purchasers pay the same standard rates as individuals plus an additional five percent surcharge, and some specialist guidance highlights much higher effective rates where corporate anti avoidance rules apply to high value residential property.
The SDLT bill alone can be substantial, and it is payable even where no cash changes hands because you and the company are connected parties.
Corporation tax and profit extraction
Once inside the company, rental profits and any future gains on sale are subject to corporation tax at the applicable rate for the year.
The tax savings are only fully realised if you retain profits in the company or use them for new investments, because taking money out personally triggers income tax or dividend tax.
Dividends above the tax free allowance are taxed at eight point seven five percent for basic rate, thirty three point seven five percent for higher rate and thirty nine point three five percent for additional rate taxpayers, so regular large withdrawals can erode the apparent benefit of the company structure.
Inheritance tax and estate planning
Holding property through a company can make share based gifting and family succession easier to manage.advantageinvestment+1
You can gradually gift shares to heirs and potentially benefit from the seven year rule for inheritance tax on lifetime transfers, though the overall position depends on your wider estate.
Commercial and practical considerations
Company mortgages are assessed differently from personal buy to let loans and usually carry slightly higher interest rates and fees.charcol+1
Not all lenders offer company buy to let products and those that do often insist on personal guarantees from directors and major shareholders, which partly offsets the limited liability protection.
You will also have ongoing company costs, including annual accounts, corporation tax returns, Companies House filings and professional fees, which can easily run to several thousand pounds per year for an active portfolio.
For landlords with only one or two properties these costs and the up front tax charges often outweigh the benefits, which is why many advisers caution against incorporation in smaller cases.
When incorporation can make sense
Incorporation tends to work best where you are a higher or additional rate taxpayer, hold mortgaged properties, and can leave profits inside the company for at least five to seven years to compound and fund further purchases.
It is more attractive where you are running a substantial lettings business rather than a small investment portfolio, and where you are comfortable with the administrative responsibilities of a company.
It may be less suitable if you are a basic rate taxpayer, intend to sell within a short time frame, need to draw most of the rent for personal living costs, or your properties already sit on large unrealised gains that would be taxed immediately without relief. In those situations keeping existing properties personally and buying any new acquisitions through a fresh company can be more efficient than transferring the whole portfolio.
How to incorporate an existing buy to let
The broad steps for incorporating personally held buy to let property are as follows.
First you set up the limited company, usually as a special purpose vehicle with appropriate SIC codes for property letting and management, and register it with Companies House and HMRC for corporation tax. You then obtain a professional valuation of the property because the transfer is treated as a market value sale, and you arrange a new company buy to let mortgage if the existing loan is in your personal name.
Next you legally sell the property to the company, complete conveyancing and register the change of ownership at HM Land Registry, with the company paying SDLT on the purchase. Finally you update tenancy agreements, insurance, deposit protection and banking arrangements so that rent flows to the company and all records reflect the new legal landlord.
Before starting this process it is essential to run detailed calculations comparing the up front CGT and SDLT and the ongoing company costs with projected tax savings over your intended holding period.

FAQs:
Is it always better to hold buy to let in a company
No, incorporation is usually only worthwhile for landlords with higher rate tax, significant mortgage interest and a long term plan to reinvest profits rather than draw them out personally. For smaller or lightly geared portfolios the up front CGT and SDLT and ongoing company costs can easily exceed any tax savings.
Can I transfer property into a company without paying tax
HMRC treats the transfer as a sale at market value, so CGT and SDLT normally arise even where you own the company yourself. Incorporation relief can defer CGT in specific cases where you transfer a genuine property business for shares, but SDLT still applies and the conditions are strict.
What happens to my existing mortgage
You cannot simply move a personal mortgage into a company; the company needs its own buy to let mortgage and the personal loan is usually repaid on completion of the transfer. Company mortgages often have different criteria and slightly higher rates, and lenders commonly require personal guarantees from directors.
Do first time landlords benefit from starting in a company
Some first time landlords choose to buy through a company from the outset to access corporation tax rates and full interest deductibility, particularly when planning a long term portfolio. However they face higher deposit requirements, fewer lender options and more administration, so personalised advice is important before deciding.
Is it easier to pass a company owned portfolio to my children?
Share transfers in a company can be simpler to structure than gifting individual properties and can help with gradual succession and inheritance tax planning.
The overall inheritance tax position still depends on valuations and your wider estate, so professional planning is recommended.
