Share Sale vs Asset Sale and Business Exit Routes: Tax Treatment

Updated 11 October 2026 · Fact-checked

A share sale is taxed once, on the owner, usually as a capital gain that may qualify for business asset disposal relief. An asset sale is taxed first in the company, then again when you extract the cash. Liquidation is usually capital. A buy-back is income unless strict conditions are met.

Understand Share Sale vs Asset Sale and Business Exit Routes

When an owner leaves a company, the question is who sells what, and who pays tax. There are three main routes. The owner sells the shares. The company sells its assets. Or the company returns cash to the owner through a liquidation or a buy-back of shares.

A share sale is simple. The owner makes a chargeable gain, taxed under capital gains tax (CGT). The rates in the ACCA tables are 18% and 24%, with an annual exempt amount of £3,000. If the company is a qualifying trading company, business asset disposal relief (BADR) can cut the rate to 14% on up to £1,000,000 of lifetime gains. The tax is paid once, by the owner.

An asset sale creates two layers. The company pays corporation tax on its gains and profits from the assets. The cash is then trapped in the company. To get it out, the owner takes a dividend or winds the company up. Dividends are taxed at 8.75%, 33.75% or 39.35%. A liquidation distribution is normally taxed as capital, so CGT applies and BADR may be available. The company gets no annual exempt amount and no BADR.

The buyer often wants the opposite result. A buyer of assets can claim capital allowances on plant and avoids inheriting hidden liabilities. A buyer of shares pays stamp duty of 0.5% and takes on the company's history. A buyer of non-residential property pays stamp duty land tax instead. So you must weigh both sides and say that the price may need to move.

A buy-back is when the company buys its own shares from the owner. By default the excess over the amount originally subscribed is a distribution, taxed as dividend income. It is taxed as a capital disposal only if strict conditions are met. Know those conditions and always check them before advising.

Key rules to remember

CGT rates (individuals): 18% lower rate; 24% higher rate; annual exempt amount £3,000; Use the tables. Gains are taxed after income, so the band left in the basic rate band decides the rate.
BADR: 14% on gains up to a £1,000,000 lifetime limit; Applies to qualifying disposals, including shares in a trading company where the conditions are met. Investors' relief has the same rate and limit but different conditions.
Share sale gain: Gain = sale proceeds − allowable costs (usually the cost of the shares); Tax is paid once by the shareholder.
Asset sale, two-layer charge: Company: corporation tax on the gain. Owner: tax on extraction (dividend or liquidation); Net cash to owner = proceeds − corporation tax − owner's tax on extraction.
Dividend rates: 8.75% basic; 33.75% higher; 39.35% additional; £500 dividend nil rate band; Use this for dividends and for a buy-back treated as a distribution.
Buy-back, default treatment: Distribution = price paid − original subscription (nominal value plus share premium); Taxed as dividend income. The company pays stamp duty of 0.5% on the price.
Buy-back, capital treatment conditions: Unquoted trading company (or holding company of a trading group); UK-resident shareholder; shares held at least five years (three if inherited); purpose to benefit the trade, not tax avoidance; holding falls to 75% or less of the former holding; holding after is 30% or less; All must be met. If not, it is income. HMRC clearance can be sought in advance.
Stamp taxes: Stamp duty on shares 0.5%. SDLT non-residential: 0% to £150,000; 2% on £150,001 to £250,000; 5% above £250,000; The buyer pays. Stamp duty is on shares and SDLT is on non-residential land.

How to solve Share Sale vs Asset Sale and Business Exit Routes questions

Use this order for any exit-route question. It keeps you on the requirement and gets the numbers and the advice marks.

1Read the requirement and list the options (share sale, asset sale, liquidation, buy-back). Note who you advise: the seller, the buyer, the company, or all of them.
2Check the facts that decide the reliefs: is it a trading company, how long has the owner held shares, what is their holding and office, and what is their other income.
3Compute the share sale first. Work out the gain, BADR if eligible (14% up to £1,000,000), then the annual exempt amount and the CGT. Use the 18% or 24% rates for any gain outside BADR.
4Compute the asset sale in layers. Do the company's corporation tax on the gain, then the owner's tax on extraction by dividend or liquidation.
5For a buy-back, test each capital treatment condition one by one. If any fail, treat it as a dividend and add the 0.5% stamp duty.
6Compare net cash after all taxes for each route. Add the buyer's view: capital allowances, stamp duty and SDLT, liabilities, and the effect on price.
7Give a clear recommendation with reasons. Mention risks (anti-avoidance on liquidations, conditions failing, timing) and any assumption you made. Finish with the professional skills marks in mind: be concise and commercial.

Quickest way: Net cash comparison in four lines

When to use it: Use this when the question asks which exit route is best and you are short of time.

Write each route as a heading: Shares, Assets then liquidate, Assets then dividend, Buy-back.
Under each, show only: proceeds, company tax (if any), owner's tax, net cash.
Test BADR eligibility and the buy-back conditions in one line each. State pass or fail.
Circle the highest net cash, then add two sentences on the buyer's preference and the main risk.

Common mistakes in Share Sale vs Asset Sale and Business Exit Routes

Ignoring the second layer of tax on an asset sale.
Students stop once the company's gain is taxed and treat the cash as the owner's.
Fix: Always carry the post-tax cash into a second step: dividend tax or liquidation CGT. Net cash to the owner is the figure to compare.
Giving the company BADR or an annual exempt amount.
Individual reliefs get applied to any disposal.
Fix: Company gains bear corporation tax with no BADR and no annual exempt amount. These reliefs are for individuals.
Treating every buy-back as a capital disposal.
The word 'sale' of shares suggests CGT.
Fix: Treat it as a distribution unless every condition is met. List the conditions and test each against the facts.
Using the wrong amount for the buy-back distribution.
Students deduct the whole share cost, or use the market value.
Fix: Take the price paid less the nominal value plus share premium originally subscribed. Only on capital treatment do you use the shareholder's CGT cost.
Forgetting the buyer's point of view and the stamp taxes.
The question seems to be about the seller only.
Fix: State that a buyer of shares pays stamp duty of 0.5% and inherits liabilities, while a buyer of assets can claim allowances. Say the price may reflect this.
Applying the annual exempt amount against the wrong gain or forgetting it.
Mixed gains at 14%, 18% and 24% cause confusion.
Fix: Set out the gains by rate. Use the annual exempt amount in the way that saves the most tax, normally against gains taxed at the highest rate, and show your choice.

Worked examples

Example 1

Ravi owns all the shares of R Ltd, a trading company, and has been a director for ten years. He is offered £1,000,000 for the shares, which cost him £10,000. Alternatively R Ltd could sell its business assets for £1,000,000, producing a chargeable gain of £990,000, and then be liquidated. Assume BADR conditions are met on both routes, no BADR limit has been used, the corporation tax rate on the gain is 25%, and ignore liquidation costs. Compare Ravi's net cash.

Show the solution

Share sale: gain = £1,000,000 − £10,000 = £990,000.
Less annual exempt amount £3,000 = £987,000 taxable at 14% (within the £1,000,000 limit).
CGT = £987,000 × 14% = £138,180.
Net cash = £1,000,000 − £138,180 = £861,820.
Asset sale: corporation tax = £990,000 × 25% = £247,500.
Cash left in R Ltd = £1,000,000 − £247,500 = £752,500, distributed in the liquidation.
Ravi's gain on liquidation = £752,500 − £10,000 = £742,500. Less £3,000 = £739,500 taxable at 14%.
CGT = £739,500 × 14% = £103,530.
Net cash = £752,500 − £103,530 = £648,970.
Difference = £861,820 − £648,970 = £212,850 in favour of the share sale.

Answer: The share sale gives Ravi £861,820 net. The asset sale then liquidation gives £648,970. The share sale is £212,850 better for Ravi because the tax is charged once. The buyer may prefer assets, so the price may need to be negotiated.

Example 2

Sam holds shares in an unquoted trading company, subscribed for £20,000 in total. The company buys them back for £200,000. Assume the capital treatment conditions are not met. Sam's other income already exceeds £125,140. Compute the tax on Sam and the stamp duty, and compare with the position if the buy-back qualified for capital treatment. Assume that if it qualified, BADR would not apply and Sam would pay CGT at 24%.

Show the solution

Distribution = £200,000 − £20,000 = £180,000, taxed as dividend income.
Sam's other income is above £125,140, so the dividend is taxed at the additional rate, 39.35%.
The first £500 falls in the dividend nil rate band. Taxable at 39.35% = £180,000 − £500 = £179,500.
Tax = £179,500 × 39.35% = £70,633.25 (rounded to the nearest penny).
Stamp duty paid by the company = £200,000 × 0.5% = £1,000.
If capital treatment applied: gain = £200,000 − £20,000 = £180,000, less £3,000 annual exempt amount = £177,000.
CGT = £177,000 × 24% = £42,480.
Saving from capital treatment = £70,633.25 − £42,480 = £28,153.25.

Answer: As a distribution, Sam pays income tax of £70,633.25 and the company pays £1,000 stamp duty. With capital treatment, Sam would pay CGT of £42,480, a saving of £28,153.25. Sam should check the conditions and consider HMRC clearance before the buy-back.

Exam tips

Most marks come from comparing routes. Show net cash after all taxes for each option, then recommend one.
State assumptions before you calculate, for example BADR conditions met and the corporation tax rate used. Examiners credit clear assumptions.
For a buy-back, go through the conditions one by one and apply each to the facts. Do not just list them.
Mention the buyer's view. Allowances, stamp duty on shares and inherited liabilities often decide what the buyer will pay.
Use the rates in the ACCA tax tables. Do not quote rates from memory when they are provided.

Share Sale vs Asset Sale and Business Exit Routes: frequently asked questions

Is it better to sell shares or assets for tax?

For the seller, a share sale usually gives a better outcome because the gain is taxed once, with BADR possibly available at 14% on up to £1,000,000. An asset sale is taxed in the company and again when the cash is extracted. The buyer often prefers assets, so you should discuss the price effect.

How is a company share buy-back taxed in the UK for ACCA ATX?

By default the shareholder is taxed as if they received a dividend, on the price less the amount originally subscribed. It is taxed as a capital disposal only if all the conditions are met, such as unquoted trading company status, five years of ownership and a substantial reduction in the holding. The company also pays stamp duty of 0.5% on the price.

Are liquidation distributions taxed as income or capital gains?

Normally a distribution in a liquidation is treated as a capital receipt, so the shareholder is taxed under CGT. BADR can apply if the conditions are met. Anti-avoidance rules can make the amount income where a shareholder liquidates and then carries on a similar business with a main purpose of avoiding income tax.

Who pays stamp duty on a share sale?

The buyer pays. The rate in the ACCA tables is 0.5% on shares. On a buy-back, the company pays the stamp duty on the price it pays.
