Key points

  1. 1Splits a business or takes property out of a trading company
  2. 2Needs no liquidator and no court application for a private company
  3. 3Reliefs and HMRC clearance usually make it tax-neutral
  4. 4Best planned well before a sale, since a main purpose test now applies

Sometimes one company holds two things that do not belong together: a trading business and the property it occupies, a safe business and a risky one, or the interests of shareholders who want different futures. A capital reduction demerger is a way of separating them into two companies, owned by the same people or divided between them, without winding up the original company.

This page is about when to use it and how it fits into your wider plans. For the detail of the steps, the company law and the clearances, see our specialist site, demergertax.co.uk. Advice here is led personally by Omar Aswat, a Chartered Tax Adviser.

Who this is for

  • Owners with property or investments inside a trading company.
  • Owners preparing for a sale, where a buyer wants only the trade.
  • Families passing different businesses to different children.
  • Shareholders who want to part ways but keep a business each.

Why a business owner would split a company

A demerger is a means to an end. The ends we see most often are:

  • A cleaner sale. The trade can be sold without the property or the surplus cash.
  • Trading status. Moving non-trading assets out helps keep the trading company clear of the 20% non-trading indicator HMRC uses for Business Asset Disposal Relief and the substantial shareholding exemption.
  • Risk. Property and investments are put beyond the reach of trading creditors.
  • Succession. Different children take different parts.
  • Parting of ways. Partners separate without a sale to a third party.

How it works in outline

In outline, a new holding company is placed above the existing company through a share exchange. That holding company then reduces its share capital, using a directors' solvency statement and a special resolution, and passes the business or property to a second new company. That company issues its shares to the shareholders. The result is two companies where there was one. The reduction takes effect once the documents are registered at Companies House, and the reserve it creates is treated as a realised profit.

How the tax works

The aim is for the whole process to be tax-neutral. Three reliefs usually work together:

  • Shareholders. Section 136 of the Taxation of Chargeable Gains Act 1992 treats the new shares as replacing the old, so no gain arises on the shareholders.
  • The company. Section 139 can treat the transfer of the business as no gain, no loss.
  • Income tax. An amount representing a repayment of capital is not a distribution, so it should not be taxed as a dividend. The transactions in securities rules still need to be cleared.

Stamp duty (0.5% on shares) and SDLT (if land moves) have their own reliefs, but they need conditions to be met. HMRC clearance is normally sought first, with a decision due within 30 days of a complete application. Since 26 November 2025, a main purpose test means the commercial reason for the split matters more than it did.

Options compared

RouteBest forMain limits
Capital reduction demergerProperty, investments or trades; most private companiesNeeds reserves via the reduction; stamp duty and clearance planning
Statutory demergerSeparating trading businesses, with no planned saleStrict conditions; not suited to a planned sale
Liquidation demergerWhere a liquidation is wantedNeeds a members' voluntary liquidation and solvency declaration
Dividend in specieVery simple casesDividend income tax on the value of the asset
SaleWhere you want cash or a clean breakTax on the gain; ownership ends

Common mistakes

  • Leaving it until a buyer appears, when the relief conditions and the main purpose test become harder.
  • Moving property first without checking SDLT group relief and its three-year clawback.
  • Ignoring stamp duty when shareholdings will not mirror.
  • Assuming a statutory demerger will fit when a sale is planned.
  • Not asking the bank, who may need to consent.

What to think about first

Before any steps, we ask a few questions. What is the commercial reason for the split? Does the company have enough value and reserves for the route? Who must consent, including shareholders, lenders and landlords? And is a sale on the horizon? The answers decide the route, the order of the steps and what to say to HMRC. A clear commercial story is the best foundation for relief under the main purpose test.

How we help

We confirm whether a demerger is the right route, compare it with the alternatives and design the steps and share structure. We prepare the HMRC clearance application, deal with stamp duty and SDLT, and brief your solicitor and accountant until completion. We have obtained 100% of the HMRC clearances we have applied for, across 50+ applications. You work directly with a Chartered Tax Adviser, and we reply the same working day.

A demerger often links to the holding company, the linked investment company and Exit Planning. See Corporate Restructuring for the wider toolkit, and The Business Lifecycle for where it fits.

Where a demerger sits in the bigger picture

A demerger is rarely the only step. It often follows the insertion of a holding company, and it can lead to a sale, an Employee Ownership Trust or a handover to the next generation. Seeing it as one link in the chain helps you choose the right moment, and avoids doing it in a way that blocks the next step.

0417 questions

Questions, answered.

Straight answers to what clients ask us most. Your own situation may differ, so treat them as a starting point.

Q1In what situations do business owners choose a capital reduction demerger?

The usual triggers are taking property out of a trading company before a sale, giving a business to a child, separating a risky venture from a safe one, or letting shareholders who disagree go their own ways. It suits cases where the assets are not purely trading, since property and investments can be moved too. If none of these apply, a simpler restructure may do.

Q2Is a demerger better than simply paying myself a dividend of the assets?

Often, yes. A dividend of property or a business is taxed as income on you, at up to 39.35% for 2026/27 on the value, even though you receive no cash. A properly structured demerger can instead pass the assets to a new company without an income tax charge, because a repayment of capital is not a distribution, and without a capital gains charge on the shareholders. The conditions and clearances matter.

Q3How does a demerger compare with selling the unwanted part of the business?

A sale gives you cash but usually triggers tax on the gain, and stops you owning the asset. A demerger keeps ownership in the same hands and, if relief applies, defers tax until you eventually sell or transfer. Choose a sale if you want money or a clean break from the asset, and a demerger if you want to keep the asset but separate it from the trade.

Q4Why would a buyer prefer me to demerge before a sale?

Many buyers want a clean trading company without surplus property or investments they have to pay for and then sell on. Separating them first can also help you keep trading status for Business Asset Disposal Relief, which is 18% on up to £1m of lifetime gains from 6 April 2026. But the timing is delicate, because relief can be refused if the main purpose is tax avoidance.

Q5Can I demerge shortly before a sale?

It is possible but needs care. A statutory demerger is generally unsuitable where a sale is planned, because the conditions look at whether the trade will be sold afterwards. A capital reduction demerger is more flexible, and HMRC guidance gives an example of a demerger before a sale to an Employee Ownership Trust that is not caught. The facts, and the commercial reasons, decide.

Q6What does the new main purpose test mean for a demerger?

Since 26 November 2025, reliefs on share exchanges and reconstructions can be denied where a main purpose of the arrangements is to reduce or avoid capital gains tax or corporation tax. A demerger that has a genuine commercial purpose, such as separating a business for family or risk reasons, is in a stronger position. Clearance from HMRC is more valuable than before.

Q7How is a capital reduction demerger different from a statutory demerger?

A statutory demerger falls under Part 23 of the Corporation Tax Act 2010 and demands that only trading businesses are separated, with strict conditions and a five-year window for chargeable payments. A capital reduction demerger uses company law to reduce share capital and pass assets to a new company, and can include property and investments. It is the more common route for owner-managed companies.

Q8Do I need a holding company first?

Usually the process begins with one. A new holding company is placed above the existing company through a share exchange, and it is that holding company that reduces its capital and passes the business on. If you already have a holding company, you may be able to use it. Our holding company page explains when it is worth having in any case.

Q9Will the demerger affect the trading company's contracts and licences?

Not normally, if the trading company stays where it is. Typically the shares of the business or property being separated are moved, not the contracts of the trading company. Where a trade itself moves, contracts, employees, licences and bank facilities may need consents. Your solicitor checks these, and we flag the points that can affect the tax plan.

Q10Do lenders need to approve a demerger?

Often they do. Loan agreements and security usually restrict transfers of assets or changes of ownership. If property secured to a lender is moving, the lender will have to consent or be refinanced. It is best to speak to the bank early, because their timetable can affect the whole plan.

Q11Can a demerger help me pass a business to different children?

Yes. A capital reduction demerger, with the shares first divided into classes, can give each child their own company. The capital gains reliefs can still apply if each class is treated equally, but stamp duty relief may be harder because the shareholdings no longer mirror. It is a common part of succession planning when different children want different parts of the business.

Q12What happens to the tax position of the new companies after the demerger?

Each becomes a separate company with its own tax return. They may be associated companies if still under common control, so the small profits limits are shared. Shareholders' base cost is split between the old and new shares. Each new company's trading status depends on what it does, and the demerged business may need its own history for reliefs such as Business Asset Disposal Relief.

Q13Can the demerged company later be sold with relief?

Possibly, but this needs planning. The relief for the sale of shares can depend on holding periods, and the two-year conditions for Business Asset Disposal Relief apply to the company being sold. HMRC guidance indicates it looks at each company, so the history of a newly formed demerged company needs checking. We model the likely result before you commit.

Q14What are the signs that a demerger is not the right answer?

If the amounts are small, the structure will be undone soon afterwards, the company lacks the reserves or solvency for a capital reduction, or a simpler step such as a sale or a dividend does the job, then a demerger may not be worth the cost. A buyer lined up for part of the business can also change which route is available. We give you a straight answer.

Q15Is a capital reduction demerger quicker than other methods?

Generally it avoids the formality of a liquidation, and a private company can reduce capital with a solvency statement instead of going to court. However, the overall timetable is driven by the HMRC clearance, which takes up to 30 days from a complete application, and by getting information, valuations and lender consent in place. Allow a few months from the first call.

Q16What is the role of the directors in a capital reduction demerger?

Directors must sign a solvency statement saying the company can pay its debts now and for the following year. This must be made on reasonable grounds, and making one without them is a criminal offence. Directors should see current management accounts and cash forecasts. We help by giving them the information the plan needs, though the statement itself is theirs.

Q17How does a demerger fit with the rest of my plans?

It is rarely a stand-alone event. It might follow adding a holding company, precede a sale or an Employee Ownership Trust, or feed a succession plan. The lifecycle view helps you see this: what comes before, and what the demerger makes possible afterwards. We plan it as one link in the chain, not as a one-off.
