Share Sale vs Asset Sale: What's the Difference?

Share Sale vs Asset Sale: An Overview

When a business changes hands in the UK, the transaction is structured as either a share sale or an asset sale. This distinction is not merely technical — it has profound implications for tax, liability, employee rights, contracts, and the overall economics of the deal for both buyer and seller.

Understanding these differences early in the M&A process is critical. The choice of structure often becomes a key negotiation point, and getting it wrong can cost either party hundreds of thousands of pounds.

What Is a Share Sale?

In a share sale, the buyer acquires the shares of the company from its shareholders. The company itself — including all of its assets, liabilities, contracts, employees, and history — remains unchanged. Ownership simply transfers from the old shareholders to the new ones.

Think of it as buying the entire "wrapper" — the company continues to exist as the same legal entity, with the same contracts, bank accounts, and tax history. Only the ownership changes.

Advantages of a Share Sale

• Tax efficiency for sellers: Proceeds are taxed as a capital gain, potentially qualifying for Business Asset Disposal Relief at 10%. This is typically the most tax-efficient structure for sellers.
• Simplicity: Contracts, licences, and employee relationships continue automatically. There's no need to novate individual contracts or obtain third-party consents (in most cases).
• Clean exit: The seller receives payment for their shares and walks away. The company's assets and liabilities remain with the company.
• Employee continuity: Employment contracts continue uninterrupted. TUPE regulations are generally not triggered in a share sale.

Disadvantages of a Share Sale

• Buyer inherits everything: The buyer acquires all liabilities — known and unknown — including historical tax liabilities, potential litigation, environmental obligations, and any other claims against the company. This risk is managed through warranties, indemnities, and thorough due diligence, but it can never be eliminated entirely.
• No tax-deductible goodwill for buyers: Unlike an asset purchase, the buyer cannot claim tax relief on the goodwill element of the purchase price, which reduces the deal's tax efficiency from the buyer's perspective.
• Complex due diligence: Because the buyer inherits all liabilities, due diligence in a share sale tends to be more extensive and more costly than in an asset sale.

What Is an Asset Sale?

In an asset sale, the buyer acquires specific assets from the company — typically including goodwill, equipment, stock, intellectual property, and customer contracts — but does not acquire the company itself. The selling company remains in existence (usually wound down afterwards) and retains any liabilities not explicitly assumed by the buyer.

Advantages of an Asset Sale

• Cherry-picking: The buyer selects which assets to acquire and which liabilities to assume, leaving unwanted obligations with the selling company.
• Tax-deductible goodwill: The buyer can typically amortise purchased goodwill for tax purposes, reducing future Corporation Tax bills. This can make the deal significantly more attractive from the buyer's perspective.
• Reduced liability exposure: The buyer takes on only those liabilities explicitly agreed in the sale agreement, avoiding hidden or historical obligations.

Disadvantages of an Asset Sale

• Tax inefficiency for sellers: The company sells its assets and pays Corporation Tax on any gains. The seller then needs to extract the proceeds — typically through a members' voluntary liquidation (MVL), which adds cost and complexity.
• Contract novation: Customer and supplier contracts may need to be individually novated or reassigned, which requires third-party consent and can be time-consuming.
• TUPE implications: Where employees transfer as part of an asset sale, the Transfer of Undertakings (Protection of Employment) regulations apply, requiring consultation and protecting employees' existing terms and conditions.
• Licence and permit issues: Regulatory licences, permits, and certifications held by the selling company may not transfer automatically and may need to be re-obtained by the buyer.

Tax Comparison: Share Sale vs Asset Sale

Tax is usually the most significant factor in the share-vs-asset debate. Consider a company being sold for £5 million with an original share cost base of £100,000:

Share sale: The seller pays CGT on a £4.9M gain. With BADR on the first £1M (10%) and 20% on the remainder, total CGT is approximately £880,000. Net proceeds: approximately £4.12M.

Asset sale: The company pays Corporation Tax (25%) on the asset gains. After CT, the remaining funds are distributed via MVL, where the shareholder pays CGT (potentially with BADR) on the distribution. The double layer of tax typically results in a higher overall liability, though the exact figures depend on the specific asset values and cost bases.

This tax differential is why sellers almost always prefer share sales, while buyers often push for asset sales to benefit from goodwill amortisation.

Why Buyers and Sellers Prefer Different Structures

The tension between buyer and seller preferences is a natural part of deal negotiation:

• Sellers want share sales for tax efficiency, simplicity, and clean exits
• Buyers want asset sales for liability protection, tax-deductible goodwill, and the ability to cherry-pick assets

In practice, for UK SME transactions, share sales are more common — particularly where the buyer is a trade acquirer who wants the company's contracts, licences, and relationships to transfer seamlessly. The buyer's concerns about inherited liabilities are typically addressed through comprehensive warranties and indemnities in the SPA, backed by warranty and indemnity (W&I) insurance where appropriate.

Our guide to business valuation discusses how deal structure can influence the headline price — a seller accepting an asset sale may negotiate a higher gross price to compensate for the additional tax burden.

Which Structure Is Right for Your Sale?

There is no universally "correct" structure — the right choice depends on the specific circumstances of your business, the buyer, and the deal dynamics. Factors to consider include:

• The size and nature of the company's liabilities
• Whether the business holds licences or contracts that are difficult to transfer
• The relative tax positions of buyer and seller
• Whether TUPE applies and how employees will be affected
• The availability and cost of W&I insurance
