Demerger Tax Advice: Capital Reduction, Statutory or Liquidation?

Quick answer: A demerger splits one company into two (or more) without a sale. Most owner-managed companies use a capital reduction demerger, because it can move property and investments as well as trades. With the right reliefs and HMRC clearance it should be tax-neutral, but the order of the steps and the commercial reason for the split decide whether that holds.

What a demerger is for

Sometimes one company holds two things that do not belong together. A trading business and the building it occupies. A safe business and a risky one. Two shareholders who want different futures.

A demerger separates them. The owners keep what they own, but it sits in different companies. The ends we see most often are:

• a cleaner company to sell, without surplus property or cash;
• protecting property or investments from trading creditors;
• keeping the trading company clear of the 20% non-trading indicator HMRC uses for Business Asset Disposal Relief (BADR) and the substantial shareholding exemption;
• giving different children different parts of the business;
• letting shareholders part ways without a sale to a third party.

If none of these fits, a simpler step may do the job.

The three routes compared

Capital reduction demerger

This is the route most private companies use. A new holding company is usually 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. The second company issues its shares to the shareholders. The reduction takes effect once the documents are registered at Companies House.

It needs no liquidator and, for a private company, no court application. It can move trades, property and investments. That flexibility is why it is the most common route.

Statutory demerger

A statutory demerger falls under Part 23 of the Corporation Tax Act 2010. It only works for trading businesses, and it has strict conditions. For five years afterwards, certain payments to shareholders can be taxed as income. It is generally unsuitable if a sale of one of the businesses is planned, because the conditions look at what happens next.

Liquidation demerger

This uses section 110 of the Insolvency Act 1986. The company goes into a members' voluntary liquidation, and the liquidator passes its businesses to new companies that issue shares to the shareholders. It can suit a group with thin reserves, or where the old company is not needed afterwards. It costs more in formality, needs a liquidator and gives dissenting shareholders statutory rights.

Simpler alternatives

A dividend in specie (paying an asset out as a dividend) is simple, but it is taxed as income on the value of the asset, up to 39.35% for 2026/27, even though you receive no cash. A sale gives you cash, but usually triggers tax on the gain and ends your ownership. A demerger is for owners who want to keep the asset and separate it.

How the tax is meant to work

The aim is a tax-neutral split. Three reliefs usually work together:

• Shareholders. Section 136 of the Taxation of Chargeable Gains Act 1992 treats the new shares as replacing the old ones, 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. 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 share transfers) and SDLT (if land moves) have their own reliefs, and each has conditions. Share-for-share relief generally expects shareholders to hold the same proportions before and after. If the shareholders take different companies, that relief may not be available. Keeping property where it is and moving only the shares avoids a land transaction.

Since 26 November 2025, a main purpose test also applies. Relief can be denied if a main purpose of the arrangements is to reduce or avoid capital gains tax or corporation tax. A genuine commercial reason is the best foundation. Our article on the Finance Act 2026 main purpose test explains the change.

HMRC clearances

Clearance is not compulsory. It gives certainty before anything irreversible happens. The usual applications are:

• section 138 and section 139(5) of the Taxation of Chargeable Gains Act 1992;
• section 701 of the Income Tax Act 2007;
• section 748 of the Corporation Tax Act 2010.

They can normally go in one application. HMRC must reply within 30 days of a complete application, although it may ask questions in that time. Questions are common and do not mean refusal. Cash, loan notes, a planned sale or a shareholder leaving the UK often prompt them.

Clearance covers only the facts you disclose. It does not deal with stamp duty or SDLT, and it does not guarantee a result if the facts differ. If HMRC refuses, nothing irreversible has happened, because clearance comes first. You can supply more information or change the plan.

Costs and timescales

The main things that drive the cost are:

• the number of companies, shareholders and classes of share;
• whether property is moving, and so whether SDLT and lender consent are in play;
• valuations and distributable reserves;
• how much HMRC asks about after the clearance application;
• legal work on the capital reduction and the new share structure.

On timing, the HMRC clearance window is up to 30 days from a complete application. Most demergers take around eight weeks from start to finish. The usual delays are not HMRC. They are information, valuations and lender consent. Banks often have to approve any move of secured property, so speak to yours early.

Common mistakes

• Waiting until a buyer appears, when the main purpose test and relief conditions get harder.
• Moving property first without checking SDLT group relief. It can be withdrawn if the buyer leaves the group within three years.
• Forgetting degrouping. A company leaving a group within six years of receiving an asset intra-group can face a charge under section 179 of the Taxation of Chargeable Gains Act 1992.
• Assuming a statutory demerger fits when a sale is planned.
• Using cash to even up values between shareholders without planning it. The reliefs expect shares, not cash.

Example: A trading company is worth £3m and also owns the office building it uses, worth £1m. The owner plans to sell the trade in three years. A new holding company is placed above the trading company by share exchange. The building is then demerged into a separate company that the owner keeps and lets to the trading company. The buyer is later offered a cleaner trading company. The figures are hypothetical. In practice the commercial reasons, the timing and the stamp duty position would be set out in the clearance application.

FAQs

What is the difference between a capital reduction and a statutory demerger?

A statutory demerger sits under Part 23 of the Corporation Tax Act 2010 and only separates trading businesses, 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.

Is a demerger better than paying myself the assets as a dividend?

Often, yes. A dividend of property or a business is taxed as income on the value, even though you receive no cash. A properly structured demerger can 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.

Can I demerge shortly before a sale?

It is possible but needs care. A statutory demerger is generally unsuitable where a sale is planned. A capital reduction demerger is more flexible, and the facts and the commercial reasons decide. Any planned sale should be disclosed in the clearance application, and the main purpose test makes the commercial reason more important than before.

Does SDLT apply when property moves between the companies?

It can. Moving land between connected companies is normally taxed on at least market value, even where no money changes hands. Group relief, reconstruction relief and acquisition relief may apply, but each has conditions and can be withdrawn if control changes or the buyer leaves the group within three years. Moving only the shares avoids a land transaction.

What happens if HMRC refuses clearance?

A refusal means HMRC is not satisfied on the facts it was given. Because clearance comes before any step is taken, nothing irreversible has happened. You can supply more information, change the plan, or in some cases ask the tribunal to decide. We would discuss the options with you before anything is signed.
