The first and most fundamental question in any company sale is whether it will be structured as a sale of the shares in the company, or a sale of the underlying assets. This matters because the tax treatment for buyer and seller is quite different, and their respective interests don’t always point in the same direction.
For the seller, a share sale is almost always preferable. The proceeds are subject to Capital Gains Tax rather than Corporation Tax, and where Business Asset Disposal Relief (BADR) applies, the effective rate can be as low as 18% on qualifying gains up to the lifetime limit. An asset sale, by contrast, typically results in the company paying Corporation Tax on any gains, with the after-tax proceeds then sitting inside the company, requiring further extraction, and potentially further tax, before they reach the shareholders.
Buyers often prefer an asset purchase because they can step up the base cost of the assets acquired and, in some cases, deduct depreciation for tax purposes. The tension between these positions is a normal part of sale negotiations, and understanding it early helps sellers hold their ground, or negotiate appropriate compensation if an asset sale is ultimately agreed.
