Acquisition Holding Company: Why Buy a Business Through a NewCo?

Quick answer: Buying a company through a new acquisition holding company (often called a NewCo or a Bidco) lets the target's profits repay the purchase debt through dividends that are normally exempt from corporation tax, rather than through taxed personal dividends. It also gives a clean home for lenders and co-investors, and a cleaner exit later. The cost is more admin, stamp duty of 0.5% on the share price and some tax conditions to get right.

What an acquisition holding company is

It is a new company, set up to buy the shares in the business you want. After the deal it is the holding company. The target becomes its subsidiary. You, and any co-investors, own shares in the new company, not in the target.

The deal is often funded in three layers:

1. Your own money, as share capital or a shareholder loan.
2. Third-party debt, such as a bank loan, borrowed by the NewCo.
3. Sometimes the seller, through deferred consideration or loan notes.

Our diagram of how a management buy-out is funded shows the typical shape. A management buy-out is one example. The same structure suits an individual buyer, a group of partners or a business buying a competitor.

Why not buy the shares personally?

You can, and sometimes you should. But the money problem usually decides the matter.

If you buy personally with a loan, the loan is yours. To repay it you need cash in your own hands. The target pays you a dividend, you pay dividend tax of 10.75%, 35.75% or 39.35% in 2026/27 depending on your band, and only what is left repays the bank. The business has earned the money, paid corporation tax and then you pay a second tax to get it to the lender.

If the NewCo owns the target and the NewCo owes the debt, the target pays a dividend to the NewCo. Dividends from a UK subsidiary to a UK parent are normally exempt from corporation tax. The NewCo uses the cash to repay the bank. There is no personal dividend tax. You pay personal tax only when you draw funds out of the NewCo.

Example: A buyer borrows £1 million to buy a company and needs £200,000 a year to service the debt. If she holds the shares personally and takes the cash as a dividend, higher rate tax of 35.75% means she would need to take roughly £311,000 of dividends to net £200,000, ignoring the allowance. If a NewCo owns the target and the target pays £200,000 up to it as an exempt dividend, the whole £200,000 reaches the lender. These figures are hypothetical and ignore the allowance and the possibility that the profits could be taxed in other ways.

This is the main practical reason for the structure. It is the same logic as in our article on moving profits up to a holding company.

The other reasons buyers use a NewCo

• Interest relief. Interest paid by the NewCo can be relieved against the target's profits if the companies are in a group for group relief, which needs a 75% relationship. Without a group, a loan in the NewCo produces interest that has no profits to relieve. Larger groups may face the corporate interest restriction, and the rules for related-party debt need care.
• Co-investors and management. Investors, a management team or family members can hold shares in the NewCo with defined rights, without touching the target's share register.
• Lender preference. Lenders often want security over the shares of the holding company and the assets of the group, with a borrower that exists only for the deal.
• Ring-fencing. The buyer's other businesses are kept apart. A problem in the target does not reach them, and vice versa.
• Future flexibility. The NewCo can buy further businesses, sell a subsidiary or bring in an investor. The substantial shareholding exemption can apply when the NewCo later sells a trading subsidiary, as long as the conditions are met.

Stamp duty and the purchase price

Buying shares in a company is subject to stamp duty at 0.5% of the price, paid by the buyer. With a NewCo, the NewCo is the buyer. The tax is on the share price. It is not stamp duty land tax, even if the target owns property, though the target's property can bring separate issues if it later moves. There is no relief for a cash purchase.

If the sellers swap their shares in the target for shares in the NewCo instead of cash, share exchange rules can defer tax for them and a stamp duty relief may apply, but only if the consideration is shares. Cash mixed in can break the relief. Clearance is available. See our article on setting up a holding company above a trading company.

Tax points to plan for

1. Interest and group relief. Model the debt, the interest and the profits to see whether the interest can actually be used. This is the most common surprise. Merging the NewCo and the target later is sometimes done to bring the interest and profits together, but it needs its own tax analysis.
2. Reserves. The target must have distributable reserves to pay the dividends. Pre-acquisition reserves are the target's own, and a share purchase does not change them. A dividend can be paid only if it is lawful, and a dividend that reduces the value of an investment can raise accounting and tax points.
3. Anti-avoidance. Where the buyer is also a seller, or the seller continues to hold an interest, the transactions in securities rules and the main purpose test (for reorganisations, from 26 November 2025) can apply. Seek clearance if there is any doubt.
4. Warranties and tax indemnities. A NewCo has no history, so the protection of the sale agreement matters more.
5. Pre-sale reorganisation by the sellers. The target may have surplus cash or property that the buyer does not want to pay for. This can be dealt with before completion, which may involve a demerger.

When a NewCo is not needed

• The price is small and no debt is involved.
• You will not bring in investors and will not buy more businesses.
• You want to buy the business and assets rather than the shares. The buyer then takes assets with SDLT on property, no inherited history and a different tax profile.
• The extra layer would create a corporate interest or VAT cost that outweighs the benefit.

Building it so that it can be sold

Plan for the exit at the start. If the NewCo is a trading group at the exit, and the conditions are met, a later sale of the whole group by the owners may qualify for Business Asset Disposal Relief, at 18% from 6 April 2026 on the first £1 million of qualifying gains, rather than the 24% higher rate for capital gains tax. A holding company with large cash balances or investment property could put that at risk. See our article on selling through a holding company or personally.

FAQs

What is an acquisition holding company?

A new company set up to buy the shares in a target business and hold them afterwards. It is sometimes called a Bidco or NewCo. After the purchase, it is the parent of the target.

Does buying through a NewCo save tax?

It can save the second layer of tax on the cash that repays acquisition debt, because dividends from the target to the NewCo are normally exempt. It does not remove corporation tax on the target's profits or tax when you take money out of the group.

Can I get tax relief on the interest?

Possibly. Interest on a loan used to buy shares can be a deductible expense of the NewCo, but it only helps if the NewCo has profits or can surrender the loss by group relief to the target. This must be modelled before the deal, not after.

How much is stamp duty on buying a company?

Stamp duty is 0.5% of the price paid for the shares, rounded up to the nearest £5, and is paid by the buyer. Different rules apply to asset purchases.

Should the NewCo be set up before the deal is agreed?

Yes, in good time. You need it for the heads of terms, the lender, the bank account, and the share purchase agreement. Setting it up is quick. Opening a bank account and agreeing the finance take longer.
