When the time comes to sell a business, the legal structure of that sale often has a bigger impact on your final tax bill than the sale price itself. Sellers broadly choose between a share sale, where the buyer acquires the company itself, and an asset sale, where the buyer purchases specific assets and the trade out of the existing company. Each route triggers Capital Gains Tax in a different way, and getting the structure wrong can be a costly mistake that is difficult to unwind once contracts are signed.
The Two Ways to Sell a Business
In a share sale, the owner sells their shares in the company directly to the buyer. The company itself continues trading exactly as before, simply under new ownership. For the seller, this is usually a single, clean disposal of a chargeable asset (the shares), which is taxed under normal Capital Gains Tax rules.
In an asset sale, the company sells its individual assets, such as property, equipment, goodwill, and stock, to the buyer. The company receives the sale proceeds, not the shareholder personally. If the shareholder then wants to extract that cash from the company, a second layer of tax can apply on top of any gain already taxed within the company.
Why Share Sales Usually Mean Simpler Capital Gains Tax
Because a share sale is a single disposal by an individual, the gain is calculated in the normal way: sale proceeds less the original cost of the shares (and certain allowable expenses), with the annual exempt amount of £3,000 available to reduce the taxable gain. If the shareholder has been actively involved in the business, this route is also the one most likely to qualify for Business Asset Disposal Relief, which can reduce the rate charged on qualifying gains to 18 percent, subject to the lifetime limit and qualifying conditions being met.
The Asset Sale “Double Taxation” Trap
Asset sales can create two separate tax charges. First, the company itself may pay Corporation Tax on any gain made when it disposes of its assets. Second, when the remaining cash is extracted by the shareholder, whether as a dividend or through a formal liquidation, a further personal tax charge can arise. Members’ Voluntary Liquidation can sometimes allow extracted funds to be taxed as a capital gain rather than income, which may still qualify for Business Asset Disposal Relief, but this requires careful planning and formal procedure well before any sale completes.
Why Buyers Often Prefer Asset Sales
It is worth understanding that buyers frequently prefer asset sales because they can choose exactly which liabilities to take on and can often obtain more favourable Corporation Tax treatment on the assets they acquire, including certain capital allowances. This means the ideal structure for a buyer is not always the ideal structure for a seller, and the eventual price agreed often reflects which side absorbs the extra tax cost of the seller’s preferred structure.
Earn-Outs and Deferred Consideration
Many business sales are not paid entirely upfront. Where part of the price is deferred or contingent on future performance (an earn-out), the Capital Gains Tax treatment depends on whether the right to future payment is itself treated as an asset at the time of sale. This is a technical area where the timing of tax charges can end up disconnected from the timing of cash actually received, so specialist advice before signing heads of terms is essential.
Practical Steps Before You Sell
Anyone considering selling a business should establish, well in advance of any offer being accepted, whether they are likely to qualify for Business Asset Disposal Relief, what their base cost in the shares or assets actually is, and how any earn-out or deferred consideration will be structured. Reviewing shareholding history, especially where shares were gifted, inherited, or acquired through an employee scheme, can also materially change the calculation.
Conclusion
Share sales and asset sales are not simply two administrative options, they are two different tax outcomes that can change what a seller actually keeps from a transaction. Structuring the deal correctly, and understanding how Business Asset Disposal Relief and the annual exempt amount interact with the chosen structure, should happen before negotiations begin rather than after a price has already been agreed.
People Also Ask
Is a share sale always better for Capital Gains Tax than an asset sale?
Not always. Share sales are usually simpler and more likely to qualify for relief, but the right structure depends on the buyer’s requirements, the assets involved, and the seller’s personal tax position.
Can I get Business Asset Disposal Relief on an asset sale?
Only indirectly, and typically through a formal Members’ Voluntary Liquidation after the company has sold its assets, rather than on the asset sale itself.
Does an earn-out get taxed immediately?
It depends on how the right to future payment is structured. Some earn-out rights are taxed as part of the original disposal, while others are taxed only as instalments are received.
