Transferring a Rental Property to a Limited Company

Moving a rental property you already own personally into a limited company is treated by HMRC and the Land Registry as a sale, even though you may still control the company that ends up owning it. That means Capital Gains Tax and Stamp Duty Land Tax (SDLT) both usually apply, in full, at the point of transfer - there is no special relief that lets a landlord move an existing property into a company tax-free just because they own both sides of the transaction.

This catches out landlords who read about the tax advantages of company ownership (covered in our guide to limited company buy-to-let) and assume the same logic applies to a property they already hold personally. Buying your next property through a company is a straightforward decision. Moving an existing one is a different, usually more expensive, question, and one worth thinking through carefully before you instruct a solicitor.

SDLT and CGT triggers

For Capital Gains Tax purposes, transferring a property into a company you control is treated as a disposal at market value, regardless of what price, if any, is actually paid between you and the company. If the property has risen in value since you bought it, you are potentially liable for CGT on that gain in the tax year of the transfer, in the same way as if you had sold it to an unconnected buyer. Our guide to Capital Gains Tax on rental property covers how the gain is calculated and what reliefs might reduce it.

SDLT works the same way in reverse: the company, as buyer, pays SDLT on the market value of the property, including the additional dwelling surcharge that applies to any purchase of a residential property when the buyer already owns another one, which a property company almost always does once it holds more than one asset. There is no exemption for the fact that you are the seller and also the ultimate owner of the buying company. If you have a mortgage on the property, HMRC also treats the mortgage balance being taken over by the company as additional consideration for SDLT purposes, on top of any cash price agreed, which can push the SDLT bill higher than landlords expect if they only budget for tax on a token or nominal sale price.

Because both taxes are charged on market value rather than on what changes hands, you generally need a formal valuation of the property at the point of transfer, and both bills are due even if you structure the "sale" between yourself and the company for £1 or for nothing at all. This is the single biggest reason transferring an existing portfolio into a company is rarely a simple administrative step, particularly for a property that has been held for many years and has built up significant unrealised gains.

A simplified worked example. Say you bought a property some years ago for £150,000 and it is now worth £280,000, with £90,000 left on the mortgage. Transferring it into a company you control would mean CGT potentially due on the £130,000 gain (after any reliefs and your annual allowance), and the company facing SDLT on the £280,000 market value, plus the additional dwelling surcharge, plus tax treatment of the £90,000 mortgage being taken over as further consideration. Even before any mortgage exit fees, that is two separate, substantial tax bills triggered by a transaction where no cash actually changed hands between you and the buyer. This is why the arithmetic needs doing properly, on your actual figures, before you commit to a transfer.

Mortgage early repayment

You cannot simply relabel an existing personal buy-to-let mortgage as a company mortgage. The property has to be sold, in the legal sense, from you to the company, which means the existing mortgage has to be redeemed and the company needs to arrange its own borrowing to complete the purchase, underwritten from scratch against the company's own accounts, the director's personal guarantee, and the property's rental income.

Redeeming an existing mortgage partway through a fixed or discounted rate period usually triggers an early repayment charge, which can run into thousands of pounds depending on how much of the deal period remains and the size of the loan. You then face the arrangement fees, valuation costs and legal fees of a brand new limited company mortgage, on top of whatever rate premium company borrowing carries over personal-name lending. Our limited company buy-to-let mortgage guide sets out how lenders assess these applications and what a specialist broker adds to the process. None of these costs are optional extras you can avoid by careful timing; they are a direct consequence of the property needing to change legal ownership.

Taken together, the mortgage redemption costs, new arrangement fees, SDLT and any CGT due can easily add up to a five-figure sum on a single average-value property, before you have gained a single pound of the ongoing tax benefit that company ownership can offer on new purchases. This is why the decision depends so heavily on your specific numbers rather than a general rule of thumb.

When it can still make sense

Despite the upfront cost, transferring existing property into a company is not automatically the wrong move. It tends to be worth serious consideration in a few situations. If you are a higher or additional rate taxpayer with a large, low-geared portfolio and many years left to hold the properties, the ongoing saving from full mortgage interest deductibility inside a company, rather than the restricted treatment under Section 24 (see our Section 24 explained guide), can outweigh a one-off transfer cost over a long enough horizon.

It can also make sense where you were already planning to sell and reinvest the proceeds anyway, since the CGT would have been payable at some point regardless, and moving into a company at the same time as a planned sale and repurchase can sometimes be more efficient than transferring later. A small number of landlords who run their letting activity as a genuine, time-intensive business, with significant hands-on involvement well beyond simply collecting rent and instructing an agent, may also be able to claim incorporation relief under Section 162 of the Taxation of Chargeable Gains Act 1992, which can defer some of the CGT. This relief depends heavily on the specific facts of how the business is run and is not available to the ordinary buy-to-let landlord who lets furnished or unfurnished property with minimal personal involvement, so do not assume it applies to your situation without a proper assessment.

Estate planning is another common reason. Holding property through a company can make it easier to pass shares to a spouse or the next generation gradually, rather than transferring whole properties, though this brings its own tax considerations around Inheritance Tax and needs its own specialist advice rather than being a side benefit you get automatically from incorporating.

Get advice

Because the tax and mortgage costs are triggered on the specific figures of your portfolio, and because a small number of landlords may qualify for reliefs that most will not, this is not a decision to make from a general guide. Get a proper calculation from an accountant who works with property investors, covering the CGT and SDLT position on your specific properties, before you approach a solicitor to start the legal transfer. A mortgage broker who specialises in limited company lending can then confirm what borrowing is realistically available to the company and at what cost, so you are working from real numbers rather than an estimate.

Ask your accountant to model at least two scenarios before you decide anything: the true one-off cost of transferring now, including CGT, SDLT, mortgage exit and new arrangement fees, and the ongoing annual saving you would expect from company ownership given your actual gearing and tax band. Dividing the one-off cost by the annual saving gives you a rough payback period, which is a far more useful number for deciding whether to proceed than looking at either figure in isolation. A transfer that pays for itself in three or four years, on a property you plan to hold for another fifteen, is a very different proposition to one that would take twenty years to break even.

How Property HQ helps

Property HQ tracks properties, mortgages and cashflow across both personal and limited company structures side by side, so if you are weighing up a transfer, you can compare the real ongoing numbers for a property under each structure rather than relying on a rough estimate before you commission formal advice.
