How to Set Up a Holding Company: Structure, Benefits and Steps

What Is a Holding Company and How Does a Group Work

In a simple group, a parent company (the holdco) owns the ordinary share capital of one or more subsidiary companies. The subsidiaries trade, employ staff and enter contracts. The parent sits above them, holding the shares and receiving any dividends the subsidiaries pay upward.

The parent and each subsidiary are separate legal entities. They each have their own directors, their own bank accounts and their own statutory obligations at Companies House. Being in a group does not merge them into a single entity for legal purposes.

Groups can be structured in different ways. A founder might have one holding company with two trading subsidiaries beneath it. Or there might be a sub-holding company in the middle, holding one cluster of subsidiaries, while the top-level holdco holds another cluster directly. The right shape depends on commercial and tax factors that a specialist adviser should map out.

Why Founders Use a Group Structure

The most common reason is risk separation. If one trading subsidiary runs into financial difficulty, its creditors generally cannot pursue the assets of the holding company or a separate subsidiary. Each company is its own legal entity with its own liability.

A group structure also makes it easier to hold certain assets centrally. Intellectual property, a freehold property or a significant brand can sit in the holdco or a dedicated IP company, then be licensed to the trading subsidiaries. This keeps the asset away from trading risk and in a stable entity.

Exits and partial sales become cleaner. If a buyer wants to acquire one business unit, you can sell the shares of that subsidiary without disturbing the rest of the group. The holding company continues to own the remaining subsidiaries.

Dividends paid by a UK trading subsidiary up to a UK holding company are generally exempt from corporation tax in the holding company, meaning profits can be accumulated at holding company level and deployed across the group or reinvested without an additional layer of tax on the dividend itself. The exemption derives from Part 9A of CTA 2009, as confirmed in HMRC's Company Taxation Manual at CTM02060.

Finally, a group structure can allow losses in one group company to be offset against profits in another, subject to strict conditions described below.

The Main UK Tax Points

There are three reliefs that founders most often hear about in the context of a holdco structure. Each has specific conditions and each requires proper professional advice before you rely on it.

Dividend exemption. As noted above, dividends received by a UK company from another UK company are generally exempt from corporation tax under Part 9A of CTA 2009. For small companies (broadly, fewer than 50 employees and turnover or balance sheet under certain thresholds), all dividends received are exempt with no further conditions. For larger companies, exemption is still available but additional conditions apply depending on whether the paying company is under the recipient's control. Even where exempt from corporation tax, dividends count as augmented profits for marginal relief calculations, which can affect the effective tax rate.

Substantial Shareholding Exemption (SSE). The SSE can exempt a gain made by a company on the disposal of shares in a qualifying trading subsidiary. The key conditions, as set out in HMRC's Capital Gains Manual at CG53070, are: the investing company must have held at least 10% of the ordinary share capital (and be entitled to at least 10% of profits and assets) of the investee company for a continuous period of at least 12 months ending no more than six years before the disposal; and the investee company must be a trading company or the holding company of a trading group at the time of disposal. The SSE applies automatically when conditions are met and no claim is required. However, the conditions are technical and fact-specific. Always take specialist advice before assuming SSE will apply to a particular sale.

Group relief. Group relief allows a company in a group to surrender trading losses (and certain other amounts) to another group company that has taxable profits, so that the claimant company can reduce its tax liability. For group relief to be available, the surrendering and claimant companies must generally be in a 75% group, meaning one must own at least 75% of the ordinary share capital of the other (directly or indirectly), as set out in the Corporation Tax Act 2010 and explained in HMRC's CTM80105. Group relief does not make the companies a single entity and there are a number of restrictions, including anti-avoidance provisions that deny relief where arrangements exist to sell the loss-making company out of the group. Relief is capped at the lower of the surrendering company's available losses and the claimant's available profits for the period.

This article summarises these reliefs at a high level for awareness purposes only. Tax law is complex and the conditions change. You must take advice from a qualified tax adviser before structuring your business in a way that relies on any of them.

Benefits and Drawbacks at a Glance

A group structure brings genuine advantages but also real costs and complexity. The table below sets out the main points to weigh up.

How to Set Up the Structure

There are two main routes depending on whether you are starting fresh or inserting a holdco above an existing company.

Route A is used where you are starting a new business or adding a new trading arm. You incorporate the holding company first, then incorporate the subsidiaries with the holding company as the shareholder from day one. This is the cleanest approach with the fewest complications.

Route B is used where you already have a trading company and want to insert a holding company above it. This is done via a share-for-share exchange: a new holding company is incorporated, the existing shareholders transfer their shares in the trading company to the new holding company, and in return they receive shares in the new holding company in the same proportions. The economic position of the shareholders is unchanged, but the holding company now sits at the top. This route typically qualifies for stamp duty relief under section 77 of the Finance Act 1986, provided the conditions are met (including that the transaction is not for tax avoidance purposes and the shareholders receive the same percentage of shares in the holdco as they held in the trading company). HMRC normally takes at least eight weeks to process a section 77 application. Advance clearance is not mandatory but is strongly advisable.

A share-for-share exchange may also engage capital gains tax rollover provisions under section 135 of the Taxation of Chargeable Gains Act 1992, which can defer any gain that would otherwise arise on the transfer. Again, this is technical and advice is needed.

Whichever route you take, engage a corporate solicitor and a tax adviser before you proceed.

Ongoing Administration

Every company in the group is a separate legal entity with separate filing obligations. Each one must file annual accounts and a confirmation statement at Companies House, and submit a corporation tax return to HMRC each year. If you have four companies in the group, you have four sets of accounts to prepare and file.

Group accounts (consolidated accounts) are a separate requirement for parent companies. A parent company must prepare consolidated group accounts unless the group qualifies as small. For accounting periods beginning on or after 6 April 2025, a group is small if it meets at least two of three tests: aggregate turnover no more than £15 million net, aggregate balance sheet total no more than £7.5 million net, and an aggregate average of no more than 50 employees. Small parent companies are exempt from filing group accounts at Companies House, though the parent must still file its own individual accounts. If your group grows beyond these thresholds, you will need to prepare audited consolidated accounts, which involves considerably more cost.

There are also internal matters to keep in order: board minutes and resolutions for each company, intercompany agreements (for management charges or loans between entities), transfer pricing awareness if you charge between group companies, and director duties owed to each separate entity. A holding company director must act in the interests of the holdco, not simply as an agent of the group as a whole.

The additional complexity and cost are real. For smaller founder-led businesses, the overhead can outweigh the benefits unless the commercial rationale for the structure is strong. Take advice before you commit.

Conclusion

A holding company structure is a powerful tool for UK founders who want to ring-fence risk, hold assets centrally, or prepare for a partial sale. The potential tax benefits, particularly the dividend exemption and the Substantial Shareholding Exemption, are genuine, but each depends on detailed conditions being met. Group relief for losses requires at least a 75% ownership link and carries its own restrictions.

The right approach is to start with commercial clarity: what are you actually trying to achieve, and is a group structure the simplest way to get there? Then take advice from a qualified UK tax adviser and corporate solicitor before you incorporate. The structure is not difficult to set up, but getting the details wrong at the outset can be costly to unwind.
