If you own more than one limited company, or you are planning to expand your business by acquiring or starting additional trading companies, a holding company structure is worth serious consideration. It is not just about organisation charts. It changes how tax applies to your group.
This guide explains how a holding company structure affects UK tax for limited companies. We cover corporation tax, dividend flows, group relief, Business Asset Disposal Relief (BADR) and the practical steps to set one up. As ICAEW qualified accountants, we work with business owners across Manchester, Birmingham, London and beyond who are weighing up whether a group structure makes sense for them.
What Is a Holding Company Structure?
A holding company structure means you have a parent company (the holding company) that owns shares in one or more subsidiary trading companies. The holding company typically does not trade itself. Its purpose is to own the shares in the subsidiaries, hold cash reserves, own intellectual property or manage group assets.
The subsidiaries carry out the actual trading activity. Each subsidiary is a separate legal entity with its own bank account, tax return and Companies House filing obligations.
For example: you run a successful ecommerce business in Shoreditch and a separate consultancy in Bristol. You could set up a holding company that owns 100% of the shares in both trading companies. The holding company receives dividends from both subsidiaries and can reinvest that cash without extracting it personally.
This structure is common once a business owner has multiple trading entities, or when they want to separate asset ownership from trading risk.
Corporation Tax in a Holding Company Structure
Each company in the group files its own corporation tax return (CT600) and pays corporation tax on its own profits. There is no group-wide corporation tax return. However, the group is treated as associated for corporation tax purposes.
Associated Companies and Corporation Tax Rates
Associated companies matter because they affect the corporation tax rate your companies pay. The 19% small profits rate applies where profits are £50,000 or less. The 25% main rate applies above £250,000. Marginal relief applies between £50,000 and £250,000.
But those thresholds are divided by the total number of associated companies in the group. A holding company plus two subsidiaries means three associated companies. The £50,000 threshold becomes £50,000 divided by 3, which is roughly £16,667 per company. The £250,000 upper limit becomes £250,000 divided by 3, roughly £83,333.
If your holding company has no taxable profits (it holds assets but does not trade), it still counts as an associated company. This can push your trading subsidiaries into the marginal relief band or the main 25% rate sooner than if they stood alone.
Example: a single trading company with £70,000 profit pays corporation tax at 19% on the full amount, because it is below £50,000? No. £70,000 is above £50,000. Marginal relief applies between £50,000 and £250,000. So a standalone company with £70,000 profit pays a blended rate around 19.75% after marginal relief. With three associated companies, the same £70,000 profit falls above the reduced upper limit of £83,333? Actually £70,000 is below £83,333, so marginal relief still applies, but the rate is higher because the thresholds are compressed.
The exact calculation depends on the distribution of profits across the group. Our advice: if you are setting up a holding company structure, model the corporation tax position first. Do not assume you will still get the small profits rate.
Dividends Within a Group
One of the main advantages of a holding company structure is that dividends paid from a subsidiary to its parent company are generally exempt from corporation tax. This is known as the exempt distribution regime under UK tax law.
Your trading subsidiary pays corporation tax on its profits. It can then distribute those post-tax profits as a dividend to the holding company. The holding company receives that dividend tax-free. The holding company can then reinvest the cash, acquire new subsidiaries, or hold it for future expansion without triggering a personal tax charge.
This is particularly useful if you want to accumulate cash centrally rather than extracting it as salary or dividends to yourself personally.
There are conditions. The subsidiary must be resident in the UK (or in a qualifying territory). The dividend must not be part of a tax avoidance arrangement. But for a straightforward UK group, the exemption works cleanly.
Group Relief: Sharing Losses Within the Group
If one subsidiary makes a loss and another makes a profit, group relief allows you to surrender the loss from one company to another. This reduces the overall corporation tax bill for the group.
Group relief applies where companies are in the same group. For a holding company structure, the holding company and its 75% subsidiaries qualify. The loss-making company surrenders its losses to the profit-making company. The profit-making company claims group relief and reduces its taxable profits.
Example: your Bristol consultancy loses £30,000 in a bad year. Your Shoreditch ecommerce company makes £100,000 profit. Without group relief, the consultancy carries the loss forward, and the ecommerce company pays corporation tax on the full £100,000. With group relief, the ecommerce company claims the £30,000 loss, paying tax on £70,000 instead. At 19% that saves £5,700 in corporation tax.
Group relief claims are made on the CT600 corporation tax return. Both companies must consent. The claim is straightforward if you have clean accounting records.
Capital Gains and Substantial Shareholding Exemption
If your holding company sells shares in a subsidiary, the gain may be exempt from corporation tax under the Substantial Shareholding Exemption (SSE). This applies where the holding company has held at least 10% of the subsidiary's shares for a continuous 12-month period within the six years before the disposal, and the subsidiary is a trading company.
SSE is valuable. It means you can sell a subsidiary and reinvest the proceeds into the group without a corporation tax charge. This is a key reason business owners use a holding company structure when they plan to exit individual trading businesses over time.
Without SSE, a holding company selling shares in a subsidiary would pay corporation tax at 25% on the gain (or 19% if below the threshold). SSE removes that entirely, provided the conditions are met.
Business Asset Disposal Relief (BADR) and Holding Companies
BADR (formerly Entrepreneurs' Relief) allows you to pay 14% CGT on qualifying disposals in 2025/26, rising to 18% from April 2026, instead of the standard 24% rate. The lifetime limit is £1 million.
For a holding company structure, BADR is available on the disposal of shares in a trading subsidiary, provided the holding company is a trading company or the holding company of a trading group. This is a specific HMRC test.
If your holding company holds significant non-trading assets (for example, a large cash reserve or investment property), it may fail the trading company test. That would disqualify the shares from BADR when you sell them.
Our advice: if you plan to use BADR on a future exit, keep the holding company's non-trading activities within limits. HMRC looks at the group as a whole, but the holding company itself must meet the trading condition.

Practical Steps to Set Up a Holding Company Structure
Setting up a holding company structure is not difficult, but it must be done correctly. Here is the process we typically follow with clients.
Step 1: Incorporate the Holding Company
You incorporate a new limited company at Companies House. This is the parent company. It will have its own director(s), shareholders, registered office and statutory registers. The holding company is usually set up with share capital that allows flexibility for future share issues.
Use a standard incorporation service. The holding company's SIC code should reflect its nature, typically 64205 (Activities of holding companies).
Step 2: Transfer Shares to the Holding Company
You transfer the shares in your existing trading companies to the holding company. This is done by a share sale agreement. The holding company buys the shares from you personally (or from the existing shareholders).
This transfer is a disposal for capital gains purposes. If the shares have increased in value since you acquired them, you may have a capital gain. However, if you transfer shares in exchange for shares in the holding company, you can claim share-for-share exchange treatment under TCGA 1992 s.135. This defers the gain until you dispose of the holding company shares.
This is a technical area. You need a solicitor to draft the share exchange agreement and an accountant to confirm the tax treatment. Do not attempt this without professional advice.
Step 3: Notify HMRC and Companies House
You must notify HMRC of the new group structure. Each company continues to file its own CT600, but HMRC will associate the companies for corporation tax purposes. You also need to update Companies House with the new shareholding structure and file confirmation statements for each company.
Step 4: Update Accounting Records and Software
Your accounting software (Xero, FreeAgent, QuickBooks or Sage) should reflect the group structure. Each company has its own organisation file. Intercompany transactions (dividends, loans, management charges) must be recorded correctly. We recommend using intercompany nominal codes to track balances between group companies.

When a Holding Company Structure Does Not Make Sense
A holding company structure is not always the right answer. Consider these scenarios where it may not be beneficial.
You have one trading company and no plans to expand. A holding company adds complexity with no real benefit. You are better off keeping the single company.
Your total group profits are below £50,000. The associated company rules will push you into marginal relief or the main rate, increasing your corporation tax bill. The administrative cost may outweigh the benefits.
You plan to extract all profits as dividends personally. If you take everything out of the company each year, the holding company serves little purpose. The cash ends up in your personal bank account either way.
You hold significant investment assets in the holding company. This can jeopardise BADR and SSE. If you want to hold investment properties, consider a separate structure or a different ownership vehicle.
Common Questions About Holding Company Structures
Does a holding company need to file accounts?
Yes. Every limited company must file annual accounts at Companies House and a corporation tax return (CT600) with HMRC. The holding company's accounts will typically show its investment in subsidiaries and any dividends received. Small groups can file abbreviated accounts or use the group accounts exemption if the group qualifies as small.
Can I be a director of both the holding company and the subsidiaries?
Yes. It is common for the same individuals to be directors of all group companies. You must keep separate board minutes and statutory registers for each company. HMRC and Companies House treat each company as a separate legal entity.
Does a holding company structure affect VAT?
Each company registers for VAT separately. There is no group VAT registration for a holding company structure unless you apply for a VAT group. A VAT group treats all members as a single taxable person for VAT purposes, which can simplify VAT returns and eliminate intercompany VAT charges. The conditions are strict. You need HMRC's approval.
What about payroll and pensions?
Each subsidiary is a separate employer for PAYE purposes. Employees are employed by the specific subsidiary they work for. You can set up a group pension scheme that covers all group companies. Speak to your payroll provider about how to structure this in software like BrightPay or Iris.
Final Thoughts
A holding company structure is a powerful tool for tax planning, asset protection and business expansion. But it comes with real costs: more administration, compressed corporation tax thresholds and the need for professional advice to set it up correctly.
If you are considering a group structure, start by modelling the tax position. Work out the corporation tax impact of associated companies. Check that BADR and SSE will still apply on your planned exit. And get the share exchange documentation right from the start.
