Capital reduction demerger
A new holding company is inserted, then reduces its capital by passing the property to a new company owned by the shareholders. Uses the reconstruction reliefs and HMRC clearances.
Trading companies
Many business owners have built up property inside their trading company: the premises, a few lets, or a growing portfolio. That can put valuable tax reliefs at risk and get in the way of a sale or succession. Separating it is possible, but the route matters.
A company that mixes a trade with investment property can face problems in three places:
Taking property out with a simple sale or dividend usually means corporation tax on the gain, income tax on the shareholders and sometimes SDLT. A demerger can avoid that double charge. If you would rather keep the property in a group than separate it, Holding Company by ASWATAX (opens in a new tab) explains how a property company can sit within a group.
A new holding company is inserted, then reduces its capital by passing the property to a new company owned by the shareholders. Uses the reconstruction reliefs and HMRC clearances.
The company is liquidated under section 110 of the Insolvency Act 1986, and the liquidator transfers the trade and property to separate new companies.
Designed for splitting trades, so it's rarely available for investment property on its own.
Each route has conditions for capital gains tax, stamp duty, SDLT and income tax, and most need advance clearance from HMRC. Since 26 November 2025 the reconstruction reliefs have used a main purpose test, so the commercial reasons need to be clear.

FAQs
Common reasons are a planned sale of the trading business, where the buyer doesn't want the property; protecting the property from the risks of the trade; passing the business and the property to different family members; and protecting tax reliefs. Investment property inside a trading company can affect Business Asset Disposal Relief, Business Relief for inheritance tax and holdover relief, because those reliefs depend on the company being mainly trading.
Yes. Business Asset Disposal Relief on a share sale needs the company to be a trading company, which means its activities don't include non-trading activities to a substantial extent. HMRC uses 20% as an indicator, looking at things like income, assets, expenses and time. A company that has built up a significant let property portfolio alongside its trade can fail that test and lose the relief for its shareholders.
Shares in a trading company can qualify for Business Relief, which from April 2026 gives 100% relief on the first £2.5m of qualifying property per person. But property that isn't used in the business is an excepted asset, so its value is taken out of the relief. If the investments become the main activity, the company can lose Business Relief altogether, because businesses mainly holding investments are excluded.
It can, but it's often expensive. If the company sells or transfers the property to you, the company is taxed on any gain at corporation tax rates. You're then taxed on the value you receive, usually as a dividend at up to 39.35%. SDLT can also arise, for example if you take over a mortgage on the property. A demerger is designed to avoid that double charge by moving the property to a new company owned by the same shareholders.
It's a reorganisation that splits a company's trade and its property into separate companies, usually both owned by the original shareholders. Done properly, it can move the property out without the corporation tax, income tax and SDLT charges that a simple transfer would bring. There are several routes, each with conditions, and most need advance clearance from HMRC. Our sister site, Demerger Tax, covers them in depth.
Usually not. The statutory demerger rules are designed for splitting trades. They require the companies involved to be trading companies or trading groups, and dealing in or holding land isn't treated as a trade for this purpose. So separating a let property portfolio from a trade normally relies on a different route, such as a capital reduction demerger or a liquidation demerger, which use the reconstruction reliefs instead.
It's a route where a new holding company is put on top of the trading company, the property is transferred up, and then the holding company reduces its share capital by transferring the property, or a company holding it, to a second new company owned by the shareholders. Company law allows this with a solvency statement, without going to court. Tax reliefs for reconstructions can then apply if the conditions are met.
The original company is placed into members' voluntary liquidation, and the liquidator transfers the trade to one new company and the property to another, with each issuing shares to the shareholders. It's well established but involves a licensed insolvency practitioner, a declaration of solvency and formal liquidation steps. It's often used where a capital reduction route isn't available, or where the company is being restructured more widely.
In practice, yes. The capital gains, income tax and transactions in securities rules all have anti-avoidance tests, and clearance applications let HMRC confirm in advance that it won't apply them. HMRC normally responds within 30 days of a complete application. Since 26 November 2025, the reconstruction reliefs have used a main purpose test, so the commercial reasons for the demerger need to be set out clearly.
There can be. SDLT reliefs exist for transfers within a group and for company reconstructions, but they have conditions and can be withdrawn if there's a change of control within three years. A market value rule also applies to transfers to connected companies. The SDLT cost often decides which demerger route is used, so it needs modelling at the start, not after the steps are agreed.
Usually, if the buyer only wants the trade. Separating it first lets you sell the trading company on its own, and keep the property, perhaps letting it back to the business. But the anti-avoidance rules look at whether the demerger is part of arrangements with a main purpose of avoiding tax, and a sale that follows soon after needs careful handling. Start well before you approach buyers.
Yes, and many do. The property company grants a lease to the trading company at a market rent. The rent is deductible for the trading company and taxable in the property company. Keeping the terms commercial and documented matters, because a buyer of the trading business will want a proper lease, and HMRC will expect arm's length terms between the two companies.
Yes, and that's often the aim. Premises used in the trade are part of the trading business, so they don't count against trading status and normally qualify for Business Relief along with the shares. It's investment property, let to outsiders or not used in the trade, that causes the problems. A demerger can be designed to move only the investment properties, leaving the business with the premises it needs.
Typically a few months from first advice to completion. Clearance applications alone take around 30 days for HMRC to respond, and longer if they ask questions. Valuations, legal documents, lender consent and accounts also take time. If you're planning a sale or a family transfer, allow plenty of time before any deadline. We respond the same working day, so an initial view can come quickly.
Not always. If the property is a small part of the company's value and income, and isn't threatening its trading status or a sale, it may be simpler to leave it where it is. A demerger has legal, valuation and advisory costs, and ongoing costs for a second company. We'll look at the numbers and tell you honestly if separating isn't worth it.
