The tax rate for Business Asset Disposal Relief (BADR) will increase to 18% (from 14%) on 6 April 2026. BADR offers a reduced Capital Gains Tax (CGT) rate on qualifying disposals such as the sale of a business, shares in a trading company or an individual’s stake in a trading partnership.

These rate increases are accompanied by new anti-forestalling rules designed to prevent individuals from securing the lower BADR rate by using early contracts. Where an unconditional contract is entered into during the 2025-26 tax year but completes on or after 6 April 2026, the disposal will normally be treated as occurring at completion, meaning the higher 18% rate applies. 

However, the legislation allows for “excluded contracts” where the contract was not entered into to secure a tax advantage and, where parties are connected, was entered into wholly for commercial reasons. Where total gains under excluded contracts do not exceed £100,000, the anti-forestalling does not apply.

The lifetime BADR limit remains £1 million meaning individuals can use the relief multiple times, provided their total gains from qualifying disposals do not exceed this threshold. However, the higher CGT rates obviously reduce the tax advantage available. Investors' Relief CGT rates are currently in line with those for BADR and will also increase to 18% in April 2026.
