Share Sale or Asset Sale: Which Structure Leaves You Better Off?
21 Oct 2026 · Unlocked · 14 min read
On the same £1,000,000 price, a founder who sells the shares can keep £820,558 after Business Asset Disposal Relief at 18%, while the same founder whose company sells its assets and pays the cash out as a dividend can keep £485,397 (worked example below, using GOV.UK rates checked 21 October 2026). Whether the deal is a share sale or asset sale decides who pays which tax and what the seller is left holding afterwards. It is a negotiated term: the buyer usually wants the opposite structure, so a seller needs to know what is at stake before heads of terms are signed.
What Is the Difference Between a Share Sale and an Asset Sale?
What is the difference between a share sale and an asset sale? In a share sale the shareholders sell the company itself, so everything inside it goes with it. In an asset sale the company sells the parts of its business the buyer wants, and the shareholders still own the company afterwards.
| Share sale | Asset sale | |
|---|---|---|
| Who sells | The shareholders | The company |
| What the buyer gets | The whole company, with its history | The assets it chooses |
| Who is taxed on the sale | The shareholders, under Capital Gains Tax | The company, under Corporation Tax, then the shareholders when the cash is paid out |
| Liabilities | Stay in the company and pass to the buyer | Stay with the seller's company unless the buyer agrees to take them |
| Employees | Stay employed by the same company | Usually transfer to the buyer under TUPE |
| What the seller is left holding | Cash | A company holding the proceeds and anything not sold |
How a Share Sale Works
What is a share sale of a business? The buyer acquires the shares, so the company's contracts, employees, assets and liabilities all stay where they are and only the owner changes. The seller receives the proceeds personally and walks away without a company to run or close.
In return, the buyer asks the seller to answer for the company's past. A share purchase agreement carries warranties about the accounts, tax, contracts and disputes, indemnities for specific known risks, and restrictive covenants that stop the seller competing for a period after completion.
How an Asset Sale Works
In an asset sale the buyer picks what it wants: stock, equipment, goodwill, customer contracts and sometimes the premises. Where the premises are included, the price and elections on fixtures affect both sides' capital allowances, which Selling a Commercial Property: Protecting Your Capital Allowances Position covers.
The price is built up from the assets chosen, a different question from valuing the company as a whole and the subject of Asset-Based Valuation: When Net Assets Set the Price. Leases, licences and customer contracts usually need the landlord's or the other party's consent to be assigned, which adds time and legal cost. The company keeps everything the buyer leaves behind, including its debts.
Share Sale or Asset Sale: The Pros and Cons for a Seller
The share sale vs asset sale pros and cons for a seller come down to three things: how many times the proceeds are taxed, how clean the break is, and how much risk the seller carries after completion.
A share sale is taxed once, on the shareholder's gain, and leaves the seller with cash and no company. The cost of that clean break is exposure: the warranties in the share purchase agreement can lead to claims against the seller after completion if a statement about the company proves untrue, which Warranties and Indemnities in a Share Purchase Agreement covers in detail. The buyer will also ask for restrictive covenants, set out in Restrictive Covenants and Non-Competes in a Business Sale.
An asset sale usually costs more tax, because the company pays tax on the sale and the shareholder pays again to take the money out. The buyer's protection rests mainly on what it chose to buy, so the warranties tend to be narrower.
The Advantages of an Asset Sale
The sale of asset advantages for a seller lie mostly outside tax:
- The seller keeps what the buyer does not want. Property, cash or a second trade can stay in the company.
- Narrower warranties. The buyer is not taking on the company's history, so it has less reason to demand protection against it.
- A sale is still possible when the company is not saleable. A business with a dispute, a tax problem or a messy history can sell its trade where no buyer would take its shares.
- Part of the business can be sold. A single division or site can be carved out without selling the whole company.
The Disadvantages of an Asset Sale
The sale of asset disadvantages fall mostly on the seller:
- Two layers of tax before the money reaches the shareholder, set out in the next section.
- A company left behind. The seller still owns a company with the proceeds, any excluded liabilities and the cost of winding it up.
- Transfer work. Each contract, lease and licence may need consent, and employees usually move to the buyer under TUPE.
- VAT questions. The sale is outside the scope of VAT only where the transfer of a going concern conditions are met.
How the Two Structures Are Taxed
The share sale vs asset sale tax implications come from who the seller is. In a share sale the shareholder is the seller and pays Capital Gains Tax on the gain. Where the gain qualifies for Business Asset Disposal Relief, the rate is 18% for disposals from 6 April 2026, up from 14% for disposals between 6 April 2025 and 5 April 2026 (GOV.UK, "Business Asset Disposal Relief", checked 21 October 2026), within a £1 million lifetime limit (HMRC helpsheet HS275, 2026). Who qualifies is covered in Business Asset Disposal Relief Explained for Company Sellers.
Gains that do not qualify are charged at 18% within the unused basic rate band and 24% above it, after the £3,000 annual exempt amount for 2026 to 2027 (GOV.UK, "Capital Gains Tax rates", checked 21 October 2026). The full computation, with base cost and sale costs, is in Capital Gains Tax When You Sell a Limited Company.
In an asset sale the company is the seller. It pays Corporation Tax on its profit from the sale at the 25% main rate where profits exceed £250,000, or the 19% small profits rate at £50,000 or less, with Marginal Relief in between (GOV.UK, "Corporation Tax rates", checked 21 October 2026). The cash then sits inside the company, and paid out as a dividend it is taxed again at 10.75%, 35.75% or 39.35% for 2026 to 2027, after a £500 dividend allowance (GOV.UK, "Tax on dividends", checked 21 October 2026). How the price is paid, whether in cash, deferred payments or loan notes, changes the outcome within either structure, which How Deal Structure Changes the Tax You Pay on an Exit covers.
A company can also be wound up after an asset sale and the cash paid out as a distribution in a winding up. HMRC's Company Taxation Manual (CTM36305, checked 21 October 2026) shows that such a distribution can be charged to Capital Gains Tax, but a targeted anti-avoidance rule treats it as a dividend where the shareholder held at least 5%, carries on a similar trade within two years and avoiding Income Tax is a main purpose of the winding up.
The UK Position From 6 April 2026
The asset sale vs share sale UK tax rates in force from 6 April 2026, with the deal taxes each side meets:
| Tax | Applies to | Rate |
|---|---|---|
| Capital Gains Tax with Business Asset Disposal Relief | Shareholder's qualifying gain on a share sale | 18% (GOV.UK, checked 21 October 2026) |
| Capital Gains Tax, standard | Shareholder's gain that does not qualify | 18% or 24% (GOV.UK, checked 21 October 2026) |
| Corporation Tax | Company's profit on an asset sale | 19% to 25% (GOV.UK, checked 21 October 2026) |
| Dividend tax | Shareholder taking the proceeds out | 10.75%, 35.75% or 39.35% (GOV.UK, checked 21 October 2026) |
| Stamp Duty | Buyer of the shares | 0.5% (GOV.UK, "Tax when you buy shares", checked 21 October 2026) |
The buyer pays the 0.5% stamp duty, £5,000 on a £1,000,000 share price (£1,000,000 × 0.5%), and a seller should expect it to be reflected in the price. On an asset sale, no VAT is charged where the sale is a transfer of a going concern: the assets are sold as part of the business, the buyer intends to carry on the same kind of business, and the buyer is or becomes VAT registered where the seller is, among other conditions in HMRC's VAT Notice 700/9 (last updated 23 May 2025).
A Worked Example: Same Price, Different Proceeds
To put the share sale vs asset sale tax implications side by side, take a founder who owns 100% of a trading company that qualifies for Business Asset Disposal Relief, with a £100 base cost and none of the £1 million lifetime limit used. The buyer pays £1,000,000 under either structure. Fees are ignored, and the asset-sale case assumes the company's taxable profit on the sale is £800,000, it has no debts, and the founder's other income already sits in the additional rate band (all illustrative assumptions).
Share sale:
- Gain: £1,000,000 − £100 = £999,900
- Taxable gain: £999,900 − £3,000 annual exempt amount = £996,900
- Tax at 18%: £996,900 × 18% = £179,442
- Founder keeps: £1,000,000 − £179,442 = £820,558
Asset sale, with the cash paid out as a dividend:
- Corporation Tax at 25%: £800,000 × 25% = £200,000
- Cash left in the company: £1,000,000 − £200,000 = £800,000
- Dividend tax: (£800,000 − £500 allowance) × 39.35% = £314,603
- Founder keeps: £800,000 − £314,603 = £485,397
The share sale leaves the founder £335,161 more (£820,558 − £485,397). In practice the prices rarely match, because a buyer of assets takes on less risk and may pay more for them.
Why the Buyer Will Push for an Asset Sale
A buyer of assets chooses what it takes on. Historic tax, disputes and claims stay in the seller's company, and the buyer can claim capital allowances on the plant and machinery it pays for. In a share sale the buyer inherits everything, and change-of-control clauses in customer contracts can require the customer's consent or let it terminate, which can erode the value the share sale is meant to deliver.
The preference hardens in some deals: a buyer carving out one division, a buyer of a distressed business, and a trade buyer that wants the customers and equipment but not the company. A private equity buyer more often buys shares, but the structure is still a term to negotiate. Whether the deal ends as a share sale or asset sale often depends on preparation: a seller who shows clean accounts, a tidy tax history and assignable contracts gives the buyer less reason to insist on assets.
Checklist: Which Structure Suits Your Exit
A sale of shares checklist to take to the accountant and solicitor before agreeing heads of terms:
- Tax position. Does the shareholding qualify for Business Asset Disposal Relief, and how much of the £1 million lifetime limit is left?
- The buyer. Is it a trade buyer after assets, or a buyer that wants the company as it stands?
- Liabilities. Are there disputes, tax enquiries or contract risks that would make a buyer refuse the shares?
- Assets to keep. Is there property, surplus cash or a second trade the seller wants to retain?
- Employees. How many staff, and on what terms, would transfer under TUPE in an asset sale?
- Contracts. Which customer contracts, leases and licences have change-of-control or assignment clauses?
- Warranty appetite. How much post-completion exposure will the seller accept for a single layer of tax?

Conclusion: Run the Numbers Before You Choose
The structure decides how much of the price the seller keeps, so the price is the first number to pin down. Run the company through the business sale valuation calculator to see how much is my business worth before choosing a structure.
The calculator gives an estimate of worth, not a price a buyer will pay, and it does not replace advice from an accountant and solicitor on which structure suits the deal.
