For years, Business Asset Disposal Relief was one of the most valuable tools available to UK entrepreneurs. Formerly known as Entrepreneurs' Relief, it allowed business owners to pay a reduced rate of capital gains tax when selling all or part of their business, rewarding the risk and work involved in building something from scratch.
The rate used to be 10% on qualifying gains up to a lifetime limit of £1 million. That meant a business owner selling a company for a £1 million gain would pay £100,000 in tax rather than the standard rate, a saving of up to £140,000 compared to the full 24% rate that applies to most capital gains.
That 10% rate is now gone. In April 2025 it rose to 14%. From April 2026 it has risen again to 18%.
To put that in concrete terms. A £1 million qualifying gain in 2024 produced a tax bill of £100,000. The same gain from April 2026 produces a bill of £180,000. That's £80,000 more in tax on exactly the same sale, purely because the rate changed underneath the business owner.
The relief still exists and still offers a saving compared to the standard 24% rate that higher rate taxpayers face on capital gains. But the gap is narrowing, and for entrepreneurs who built their exit strategy around the original 10% rate, the numbers have changed significantly.
The lifetime limit remains at £1 million of qualifying gains. The two year ownership and employment conditions still apply. But the value of reaching that limit has been reduced with every rate increase.
If you're running a business and thinking about an eventual exit, whether that's a sale, a management buyout, or passing it on, the tax position on that exit has changed materially in the last two years. What you planned around and what the bill will actually be when the time comes may now be two very different figures.
Know your exit tax position before you need it, not after you've agreed a deal.
