Business Asset Disposal Relief (BADR), explained

BADR cuts the Capital Gains Tax you pay when you sell your UK business — up to a £1m lifetime limit. Here’s the current rate, who qualifies, and how to avoid losing the relief on an earn-out.

📅 Last reviewed: June 2026. UK CGT rates and reliefs change with every Budget and depend on your circumstances. This is general information, not tax advice — confirm the current position with HMRC and a qualified adviser before acting.

When you sell a trading business, BADR can be the difference between a 24% tax bill and a materially lower one on your first £1m of gains. But the rate has risen recently, and the qualifying conditions trip people up — especially on earn-outs.

What is BADR?

Business Asset Disposal Relief (BADR) is a Capital Gains Tax relief for people selling all or part of a trading business. It was previously called Entrepreneurs’ Relief (renamed by Finance Act 2020). It applies a reduced CGT rate to qualifying gains, up to a £1,000,000 lifetime limit per person.

The current BADR rate (it has gone up)

This is the part most owners get wrong — BADR is no longer the old 10%. The rate has been increased in stages:

PeriodBADR rate on qualifying gains
Up to 5 April 202510%
6 April 2025 – 5 April 202614%
From 6 April 202618%

For context, standard CGT in 2026-27 is 18% (basic rate) and 24% (higher/additional rate), with a £3,000 annual exempt amount. So BADR at 18% still helps a higher-rate seller on the first £1m of qualifying gains — but the gap has narrowed, which makes deal structure and timing matter more than ever.

Who qualifies?

For a sale of shares, you generally need all of the following for at least 24 months before the sale:

Sole traders and partners selling the business (or their share of it) can also qualify on different but related conditions. The £1m lifetime limit applies across all your claims.

A worked example

£1m qualifying gain — BADR vs standard rate (from April 2026)

Qualifying gain£1,000,000
CGT at standard higher rate (24%)£240,000
CGT with BADR (18%)£180,000
Saving£60,000

The annual exempt amount and your other gains will adjust the exact figure — this is illustrative.

Don’t lose BADR on an earn-out

If part of your price is a performance-based earn-out, beware: an unascertainable earn-out is treated as a separate CGT asset (the Marren v Ingles principle). The initial disposal can get BADR, but the later earn-out receipts usually don’t.

This is genuinely technical. Earn-out and loan-note structuring has to be set up before you sign. Model it with a Chartered Tax Adviser early — the right structure can be worth tens of thousands.

Frequently asked questions

What is the BADR rate in 2026?

18% on qualifying gains from 6 April 2026 (it was 14% for 2025-26, and 10% up to 5 April 2025), up to a £1m lifetime limit. Standard CGT is 18%/24%. Confirm the current rate with HMRC — it changes with each Budget.

Who qualifies for Business Asset Disposal Relief?

For a share sale: generally 5%+ of ordinary shares and voting rights, employee or officer status, and a trading company — all for 24 months before sale. A £1m lifetime limit applies.

What is the lifetime limit?

£1 million of qualifying gains per person. Gains above it are taxed at the standard rate (24% for higher-rate taxpayers).

Can I get BADR on an earn-out?

The initial disposal can qualify, but unascertainable earn-out receipts usually don’t (Marren v Ingles). Loan notes with a s.169Q/R election can preserve the relief — take specialist advice.

Is BADR the same as Entrepreneurs’ Relief?

Yes — BADR is the renamed Entrepreneurs’ Relief (Finance Act 2020). Conditions are broadly the same; the rate and limit have changed over time.
