Share Sale vs Asset Sale: Tax, Liabilities, TUPE and Which to Choose

Share sale vs asset sale: the short answer

In a share sale the owner changes but the company does not; in an asset sale the company stays with the seller and only the chosen assets move. A share buyer inherits the company's history, including unknown liabilities; an asset buyer leaves them behind but must transfer every asset and contract separately. The seller differs too: shareholders in a share sale, the company itself in an asset sale.

What transfers in each structure: liabilities, contracts, licences and employees

The direct answer is that a share sale transfers everything by default and an asset sale transfers only what is listed.

Liabilities

On a share sale, tax arrears, product claims, pension deficits and litigation stay inside the company, so their cost passes to the buyer with the shares, and its protection is contractual. On an asset sale, the buyer takes only the liabilities it agrees to assume, which is why asset deals are the standard route out of insolvency. Our guide to what happens when a company goes into administration explains why administrators almost always sell assets rather than shares.

Contracts, licences and property

A company's customer, supplier and financing contracts stay in place on a share sale, because the contracting party has not changed. On an asset sale each contract must be assigned or novated, and many forbid assignment without consent. Leases need landlord consent, registered intellectual property must be re-registered, and licences tied to the holder may not transfer at all, which can make a share sale the only realistic route for a licence-dependent business.

Employees and TUPE

On a share sale the employer does not change, so employment contracts simply continue and the Transfer of Undertakings (Protection of Employment) Regulations 2006 are not normally engaged. On an asset sale of a business that keeps its identity, regulation 4 of TUPE makes the assigned employees' contracts take effect as if made with the buyer, and passes the seller's duties and liabilities under them to the buyer. Both parties also owe information and consultation duties, and a later hive-up of the business into another group company can itself engage TUPE. With the Employment Rights Act 2025 changes being phased in, employee liabilities deserve close attention on either structure, and specialist employment lawyers are usually part of the deal team.

Consents, change of control and regulatory approvals

Asset sales need more third-party consents, but share sales are not consent-free. Key contracts, facility agreements and leases often contain change of control clauses that let the counterparty terminate or renegotiate when ownership changes, so they must be found in diligence and waivers obtained before signing or as conditions to completion.

Other approvals depend on the business and the deal size. Regulated businesses may need the regulator's approval of a new controller, larger deals can need merger control clearance, and some sectors face national security screening; the multi-jurisdiction antitrust review of the Paramount Skydance and Warner Bros. deal showed how approvals can dictate the timetable. Articles and shareholders' agreements may also contain pre-emption rights that must be waived on a share sale. Since 18 November 2025, Companies House identity verification has been mandatory for new directors and people with significant control, so board changes at completion need planning.

Due diligence, warranties, indemnities and W&I insurance

Because a buyer of shares takes the company's whole history, share sale due diligence is wider and the contractual protection is heavier. The buyer reviews tax, employment, contracts, litigation, property and compliance, then negotiates warranties in the share purchase agreement and specific indemnities for known risks, usually including a tax covenant.

On an asset sale, diligence concentrates on title to the assets, transferability of contracts and the employees moving under TUPE, and the warranties are narrower. In both structures sellers limit exposure through disclosure, caps, time limits and de minimis thresholds.

Warranty and indemnity insurance has become a common way to bridge the gap. The buyer insures against breach of the warranties, so the seller can accept a low cap and the buyer has a solvent insurer to claim against. Policies generally exclude matters the buyer already knows about, so W&I cover supplements diligence rather than replacing it. Where the target is distressed, buyers usually combine an asset structure with advice from insolvency and restructuring specialists, because sales by insolvency office holders typically carry limited warranties.

Share sale vs asset sale tax in the UK: what the seller pays

For sellers, the share sale vs asset sale tax comparison usually favours a share sale, because individuals pay Capital Gains Tax once on their gain, while an asset sale can produce two layers of tax. The rates below are those in force for disposals on 3 November 2026.

Individual shareholders: Capital Gains Tax and BADR

The Budget 2026 rates and allowances set Capital Gains Tax at 18% for gains within the basic rate band and 24% above it for 2026 to 2027, with an annual exempt amount of £3,000. Business Asset Disposal Relief now charges qualifying gains at 18%: the GOV.UK guidance on Business Asset Disposal Relief lists 18% for disposals from 6 April 2026, up from 14% in 2025 to 2026 and 10% before that. To qualify on a share sale, the seller must for at least two years be an employee or office holder of a trading company or trading group holding company and, unless the shares came from an EMI option, hold at least 5% of the shares and votes with a matching economic entitlement.

Because the BADR rate now equals the basic rate, its value lies in the 6 percentage point saving against the 24% higher rate, worth up to £60,000 on the current £1 million lifetime limit. HMRC's tax information note states that the limit falls to £500,000 for qualifying disposals made on or after 6 April 2027, which halves the maximum saving to £30,000, with anti-forestalling rules for contracts entered into before that date but completed afterwards. Budget 2026 also announced a new Founders' Relief at a 10% rate for qualifying disposals from 6 April 2027, subject to a consultation closing on 30 November 2026.

Corporate sellers: the substantial shareholding exemption

Where the seller is itself a company, the gain on a share sale can be exempt altogether. Under Schedule 7AC to the Taxation of Chargeable Gains Act 1992, the substantial shareholding exemption applies where the selling company has held at least 10% of the ordinary share capital, with matching rights to profits and assets, throughout a twelve-month period beginning not more than six years before the disposal, and the company sold is a trading company or the holding company of a trading group.

Asset sales: the double tax charge

On an asset sale the company pays Corporation Tax, at a main rate of 25%, on its gains and on any balancing charges. The shareholders then pay tax again when the cash is extracted, as income tax on a dividend or Capital Gains Tax on a distribution in a liquidation, where BADR may be available. Sellers planning to leave the UK should read our guide on how to become non resident for UK tax first.

Tax for the buyer: stamp duty, SDLT, VAT and the tax base

Buyers tend to prefer asset deals for tax reasons, but transfer taxes can point the other way. HMRC's guidance on tax when you buy shares sets stamp duty at 0.5% where shares are bought with a stock transfer form and the price is over £1,000. Budget 2026 confirmed that a new Securities Transfer Tax will replace Stamp Duty and Stamp Duty Reserve Tax from late 2027.

An asset purchase including land in England or Northern Ireland attracts Stamp Duty Land Tax. For non-residential property the Budget 2026 tables show 0% up to £150,000, 2% to £250,000 and 5% above, so a property-rich business can cost far more to buy as assets than as shares. Our earlier report on SDLT thresholds covers the residential bands.

VAT is the other trap. Under VAT Notice 700/9, a transfer of a going concern is not a supply for VAT if the assets can operate as a business, the buyer carries on the same kind of business, is VAT registered or required to register, and there is no significant break in trading. The rules are compulsory, mistakes can bring penalties and interest, and land the seller has opted to tax needs the buyer to opt and notify too. A share sale is never a TOGC, because the assets stay with the company.

The asset buyer's long-term advantage is a fresh tax base: the price is allocated across the assets, supporting capital allowances on plant and relief on acquired intangibles, whereas a share buyer inherits the company's existing tax values.

Share sale vs asset sale: which should you choose?

Choose a share sale when continuity matters and the company is clean; choose an asset sale when the buyer needs to leave liabilities behind or only wants part of the business. In practice it is negotiated, with price, warranties and W&I cover moving to compensate.

Choose a share sale if	Choose an asset sale if
The business depends on contracts, permits or licences that cannot easily be assigned	The target has known or suspected historic liabilities
The sellers are individuals who qualify for BADR, or a company that qualifies for the substantial shareholding exemption	Only one division, product line or set of assets is being bought
The business owns valuable land, so SDLT would be significant	The company is insolvent or in an administration process
The seller wants a clean exit with no company left to wind up	The buyer wants a fresh tax base and control over which staff and contracts move

Cross-border deals: why the answer changes by country

The same choice exists almost everywhere, but the rules behind it do not. Transfer taxes, capital gains rules, employee transfer regimes and formalities differ by country. In Germany, for example, employment relationships pass to the buyer automatically when an asset deal amounts to a transfer of a business under section 613a of the German Civil Code, and transfers of GmbH shares require notarisation. Local counsel, such as advisers in our Germany directory, should confirm the position before heads of terms.

When to instruct M&A lawyers and tax advisers

Bring in advisers before heads of terms, not after, because the structure fixes the price mechanics, the tax and the timetable. Instruct corporate and M&A lawyers in the United Kingdom to scope diligence, map consents and draft the agreement, and a UK tax adviser to model CGT, BADR, the substantial shareholding exemption, SDLT and VAT before the price is agreed. With the BADR lifetime limit falling on 6 April 2027, sellers weighing a 2027 exit should take advice now on timing and on the anti-forestalling rules. For other jurisdictions, start from our corporate, commercial and M&A directory or the wider tax adviser listings.

Frequently asked questions

What is the main difference between a share sale and an asset sale?

In a share sale the shareholders sell their shares, so the buyer acquires the company with all its assets, contracts, employees and liabilities. In an asset sale the company sells selected assets, and the buyer takes only what the agreement lists, with liabilities generally staying behind.

Do you pay tax on a share sale?

Individual sellers pay Capital Gains Tax at 18% or 24%, or 18% on gains qualifying for Business Asset Disposal Relief. A company selling a qualifying stake of 10% or more may be exempt under the substantial shareholding exemption. The buyer pays 0.5% stamp duty.

Does TUPE apply to a share sale?

Not usually. On a share sale the employer stays the same, so employment contracts continue unchanged. TUPE normally applies to an asset sale of a business that keeps its identity, moving the assigned employees and related liabilities to the buyer.

Why do buyers prefer an asset sale?

An asset sale lets the buyer choose which assets and liabilities it takes, leaving unknown historic liabilities with the seller. It also gives the buyer a fresh tax base in the assets. The trade-off is more consents, TUPE obligations, possible SDLT on land and more work to transfer each contract and licence.

What is changing to Business Asset Disposal Relief?

The BADR rate is 18% for disposals from 6 April 2026. Budget 2026 confirmed that the lifetime limit will fall from £1 million to £500,000 for qualifying disposals made on or after 6 April 2027, with special rules for contracts entered into before that date but completed afterwards.

Is VAT charged on an asset sale?

VAT is not charged if the sale qualifies as a transfer of a going concern under HMRC's rules, which are mandatory. If the conditions are not met, VAT is due on taxable assets at the normal rate. Land opted to tax needs the buyer to opt and notify before completion for TOGC treatment.
