Transferring Buy to Let to a Limited Company
Moving a personally owned buy to let into a company is not a transfer at all in HMRC's eyes. It is a sale, and pricing that sale correctly, stamp duty, capital gains and new finance, is the difference between a smart restructure and an expensive mistake.
Transferring a buy to let to a limited company means selling the property from yourself to a company you own. Because it is a sale at market value, it can trigger capital gains tax on any gain and stamp duty land tax for the company, including the 5% additional dwelling surcharge. The company also needs a new mortgage, as the old personal one cannot move across. Incorporation relief can defer the capital gains charge where the letting is run as a genuine business, but it does not remove the stamp duty. The saving on future rental income tax has to outweigh these upfront costs.

Why 'transfer' is the wrong word
Landlords picture moving a property into a company as retitling it, a bit of paperwork and a small fee. HMRC sees something very different. You and your company are separate legal persons, so the company buys the property from you at its current market value. Every tax that applies to a normal sale and purchase applies here too.
That single fact drives the whole cost. The company pays stamp duty as a buyer, you may owe capital gains tax as a seller, and the property needs fresh finance because a mortgage cannot simply follow it across. None of this makes incorporation a bad idea, but it does mean the decision has to be modelled, not assumed.
This is one branch of the wider limited company property finance decision. If the driver is tax, read section 24 mortgage interest relief first, because that is usually the reason to move at all.
The three costs of moving property in
There are three upfront costs to price before you commit. Each is a real cash outflow, and together they set the bar the future tax saving has to clear.
| Cost | Who pays | What drives it |
|---|---|---|
| Stamp duty land tax | The company (buyer) | Property value, plus the 5% additional dwelling surcharge on every band |
| Capital gains tax | You (seller) | The gain since you bought, at the residential CGT rate, unless deferred |
| Refinancing costs | The company | New mortgage arrangement fee, product fee, valuation and legal costs |
Because the company is a corporate buyer of a dwelling, it pays the higher rates of stamp duty on the whole purchase price. There is no first property exemption for a company: the additional dwelling surcharge applies from the first pound.
Model the stamp duty precisely before you move: our limited company buy to let stamp duty guide and the landlord stamp duty calculator show the exact figure for your property value.
Capital gains tax and incorporation relief
Selling to your company crystallises any gain you have made since buying. If the property has risen in value, capital gains tax is due on that gain at the residential rate, after your annual exemption. On a property owned for many years, this can be the largest single cost of the whole exercise.
Incorporation relief can defer that charge, but only where the letting activity is a genuine business rather than passive investment. HMRC looks for a portfolio run with real time and effort, often taken to mean around 20 hours a week of active management. Where relief applies, the gain is rolled into the shares of the company rather than taxed now, deferring rather than deleting the liability.
It depends on your portfolio genuinely being a business, and the test is a matter of fact and degree that HMRC can challenge. A single buy to let almost never qualifies. Do not assume the relief: confirm it with a qualified accountant before you rely on it in your numbers.
Refinancing: the company needs its own mortgage
Your existing personal buy to let mortgage cannot transfer to the company. The company is a new borrower buying the property, so it needs a new limited company buy to let mortgage, with its own valuation, legal work and a personal guarantee from you as director. The old mortgage is redeemed as part of the sale.
This is where the sequencing matters. The company must have the finance agreed and the deposit in place, usually via a directors loan, before completion. We structure this so the new company mortgage completes as the personal one is redeemed, keeping the rental income flowing without a gap.
We arrange the company side of this every week. The limited company buy to let mortgages page sets out lender appetite, and deposits and directors loans covers getting the cash into the company cleanly.
When it is worth doing, and when it is not
The logic is a payback calculation. The upfront cost of stamp duty, any capital gains tax and refinancing is set against the annual saving on rental income tax inside the company. A higher rate landlord with a large mortgage and years of holding ahead can recover the cost and pull ahead. A basic rate landlord, or one close to selling, often never gets the money back.
- Value the property and work out the latent capital gain.
- Price the company's stamp duty, including the 5% surcharge.
- Check whether incorporation relief can defer the capital gains tax.
- Estimate the annual saving on rental income tax versus staying personal.
- Divide the upfront cost by the annual saving to find the payback period.
This guide explains the mechanism, not your liability. Stamp duty, capital gains tax and incorporation relief all turn on specifics we cannot see, and getting any one wrong is costly. Speak to a qualified accountant and a conveyancer before transferring anything, and let us structure the finance once the plan is set.
- Incorporation relief
- A capital gains tax relief that can defer the gain when a genuine property business is transferred to a company in exchange for shares.
- Capital gains tax (CGT)
- The tax on the increase in a property's value since purchase, due when you sell, including a sale to your own company.
- Additional dwelling surcharge
- The extra 5% of stamp duty applied to every band on additional residential property, which a company always pays.
- Directors loan
- Money a director lends to the company, commonly used to fund the deposit for the new company mortgage on transfer.
Transferring Buy to Let to a Limited Company: common questions
How much does it cost to transfer a property into a limited company?
Budget for three costs: stamp duty paid by the company including the 5% additional dwelling surcharge, capital gains tax on any gain since you bought unless incorporation relief defers it, and refinancing costs for the company's new mortgage. On a property with a large gain and no relief, these can run to tens of thousands of pounds, which is why the future tax saving has to be modelled against them.
Is it better to buy a buy to let through a limited company?
For new purchases by a higher rate taxpayer building a portfolio, a company usually improves the after tax return because mortgage interest stays fully deductible from rental income. Transferring an existing property in is harder to justify because of the upfront stamp duty and capital gains cost. Buying future properties in the company while leaving existing ones personal is often the pragmatic middle path.
How can I avoid paying 40% tax on rental income?
The main routes are holding property in a limited company, where profit is taxed at corporation tax rates and mortgage interest is fully deductible, or reducing taxable rental income through allowable expenses and pension contributions. Moving existing property to a company has its own upfront tax cost, so it is not a shortcut. Take accountancy advice, because the right answer depends on your total income and plans.
Is it worth transferring property to a company?
It is worth it when the annual saving on rental income tax recovers the upfront cost within a period you are comfortable with, typically because you are a higher rate taxpayer holding for the long term with a sizeable mortgage. It is rarely worth it for a basic rate taxpayer, a single low geared property, or anyone likely to sell soon. Run the payback calculation with an accountant before deciding.
