Setting Up a Holding Company Above a Trading Company: Process, Clearances and Stamp Duty

Quick answer: A holding company is usually placed above your trading company through a share exchange, which is normally tax-neutral for the shareholders. HMRC clearance is sensible before the shares are issued, and stamp duty relief needs the shareholdings to mirror each other. It is worth doing when surplus cash is building or a sale, investment or succession is coming. It is not worth doing for every company.

Should you add one at all?

Almost any company can have a holding company put above it. The harder question is whether it improves your position. Three questions help:

1. Does the trading company make more cash than you need personally?
2. Do you plan to start, buy or sell a business, or bring in investors?
3. Do you hold property or investments that should sit away from trading risk?

If the answer to all three is no, you may not need one yet. If one or more is yes, it is worth costing.

The process, step by step

1. Agree the purpose and test the numbers. This includes the corporation tax effect and the trading-status position.
2. Form the new company with the same shareholders, in the same proportions.
3. Apply for HMRC clearance. See below. The share exchange is made conditional on it.
4. Carry out the share exchange. Shareholders swap their shares in the trading company for shares in the new company. Section 135 of the Taxation of Chargeable Gains Act 1992 treats the new shares as the old ones. There is no disposal, and the base cost and acquisition date carry over.
5. Deal with stamp duty. Claim share acquisition relief, which needs adjudication by HMRC.
6. Update the registers. The holding company becomes the sole shareholder, so the trading company's register of people with significant control will show the holding company. You then appear on the holding company's record.
7. Set up the basics. The holding company needs a director, a registered office, statutory registers and its own bank account.

Your solicitor drafts and files the documents. We design the tax plan, brief the solicitor and review the documents for tax before anything is signed.

Clearances

Clearance is not compulsory, but it is often worthwhile. The usual applications are:

• section 138 of the Taxation of Chargeable Gains Act 1992, confirming the exchange is not caught by the anti-avoidance rule;
• section 701 of the Income Tax Act 2007, for the transactions in securities rules.

They often go in one application. HMRC must respond within 30 days of a complete application, and may ask questions in that time. A section 138 clearance has to be obtained before the shares are issued, so issuing early defeats the point of applying.

Since 26 November 2025, a main purpose test applies to share exchanges. Relief can be denied where a main purpose is to reduce or avoid capital gains tax or corporation tax. The old protection for holders of 5% or less has gone. A genuine commercial reason, such as protecting assets, bringing in a partner or preparing for succession, is the right footing. Our article on the main purpose test has the detail.

Stamp duty

Stamp duty on shares is 0.5% of the consideration. Share acquisition relief can remove it, but only in the right circumstances:

• the consideration must be shares only. Cash to one shareholder defeats the relief for the whole transaction;
• the share classes and proportions must match, so issuing different classes in the new company is likely to fail;
• arrangements for a buyer to obtain control of the new company can be disqualifying, unless the buyer already held at least 25% throughout the previous three years.

If family members are to receive shares, it is often cleaner to complete a mirror-image exchange first and change the share capital later as a separate step.

The corporation tax catch

A holding company usually counts as an associated company. The £50,000 and £250,000 profit limits for the lower corporation tax rates are then divided between the companies. For two companies, each has limits of £25,000 and £125,000. The holding company escapes this only if it is purely passive: it holds only shares in subsidiaries, has no income but dividends, passes those on in full and claims no expenses.

If the trading company is highly profitable, this rarely matters. For a smaller one it can cost real money. Our article explains how a holding company affects corporation tax.

Protecting reliefs on a later sale

A holding company can give you choices on a sale. If it sells a subsidiary it has held for 12 months and which has been trading throughout, the substantial shareholding exemption can mean no corporation tax on the gain. Or you can sell the holding company itself and qualify for BADR, if the group is trading.

BADR is 18% on up to £1m of lifetime gains from 6 April 2026. It needs two years of trading status, and HMRC treats more than 20% non-trading activity across the group as substantial. If the holding company accumulates large cash balances or investments, the group could fail the test. A linked investment company outside the trading group is one answer. Doing this early matters, because waiting for a buyer may be too late.

Timescales

A share exchange without clearance can be done in a few weeks. With clearance, plan for two to three months from the first call, including HMRC's 30-day window. A regulated business needs more time: some regulators treat a new company in the ownership chain as a change of controller, and their timetable can be longer than HMRC's. Lender consent can also affect timing.

Common mistakes

• Adding one too late, after a buyer has appeared and relief periods cannot be met.
• Letting cash pile up in the holding company until the group no longer looks like a trading group.
• Ignoring associated companies and losing the lower corporation tax rate without noticing.
• Changing ownership at the same time, which adds gift, valuation and stamp duty questions.
• Issuing the new shares before clearance arrives.

Example: A company makes £300,000 a year after tax, and the owner needs £100,000. Without a holding company, the surplus £200,000 stays in the trading company, exposed to trading risk and sitting inside the trading-status tests. With one, the surplus can be paid up as an exempt dividend and invested by the holding company, for example in a second venture. The figures are hypothetical. The corporation tax effect of associated companies would be tested first.

FAQs

Is a holding company worth it for a business making modest profits?

Often not yet. A holding company adds a second set of accounts, a second tax return and some legal cost. Its benefit grows with the surplus profit you can move up and the value you want to protect. If you spend nearly all your profits personally, little cash moves up and the gain is small.

Will adding a holding company make me pay more tax?

It should not if designed well, because moving shares up is typically tax-neutral through a share exchange and dividends between companies are normally exempt. The costs to watch are the loss of the small profits rate through associated companies, stamp duty if reliefs are not available, and extra compliance. We test these before recommending anything.

Can my existing trading company become the holding company?

It can, through a hive-down, where the existing company moves its trade and assets into a new subsidiary and keeps the shares. This is less common because contracts, staff, licences and property all have to move, which brings legal work and tax points such as SDLT. Placing a new holding company above the existing one normally leaves the trading company untouched.

Do contracts and bank facilities change?

Normally not. A share exchange above the existing company leaves the trading company as it is. Loan agreements and key contracts may still have change-of-control clauses, so your solicitor should check them. Lenders often want to be told even when nothing changes in substance.

What if I change my mind later?

You can usually unwind or reshape the structure, but it may involve further tax and stamp duty and, if done soon after, closer HMRC scrutiny. That is why we plan the exit route before setting up. A structure designed with change in mind is far easier to adjust.
