Business Asset Disposal Relief: Keep 86 Percent of Your Sale Proceeds.
Selling a company is often the reward for years of graft, so the last thing you want is an unexpected tax shock. Business Asset Disposal Relief (BADR) lets qualifying gains fall under a 14 percent capital-gains tax (CGT) rate for the 2025–26 tax year. The main rate sits at 24 percent, so the relief can drop your bill by up to ten points. Even better, each person enjoys a £1 million lifetime ceiling, and spouses can combine their limits. This guide walks you through every rule, every timing trick, and every pitfall—using plain English—so you leave HMRC only what you must.
Why BADR matters now
From 6 April 2025 the BADR rate climbs from ten to fourteen percent. The Government already signalled an 18 percent headline for gains after 5 April 2026. Acting during the current window can carve out a permanent saving on the first £1 million of gain. On a typical exit the numbers speak loudly:
-
Gain: £1 million
-
Tax with BADR (2025–26): £140 000
-
Tax at standard CGT (higher-rate band): £240 000
That extra £100 000 lands in your pocket, which could fund growth in a new venture, children’s school fees, or an earlier retirement. Planning early ensures you do not trip over the conditions.
Who can claim?
BADR rewards people who build and run genuine trading businesses. In simple terms you need:
-
A qualifying disposal – such as a full or part sale of a sole trade, partnership interest, or shares in a “personal trading company.”
-
A two-year holding period – the asset (or the shares) must sit in your hands for at least twenty-four months up to the sale date.
-
Employee or office-holder status (for shares) – directors, company secretaries, paid advisers, and paid non-executives count.
-
At least five-percent stake (shares) – you must own five percent of the ordinary share capital and five percent of votes and five percent of both profits and sale proceeds.
-
Trading status – the company’s non-trading activities (e.g., property letting, surplus cash, share portfolios) stay below roughly twenty percent of turnover, assets, and management time.
Meet each rule for two clear years and the relief locks in. Drop any test—say your holding dilutes to 4.8 percent after an investment round—and HMRC can deny BADR.
Seven ways to lock in the Business Asset Disposal Relief.
Start the clock early
You cannot manufacture a two-year history at the last minute. Record when you first meet every test: the date you became a director, the date you reached five percent, and the date the company started trading. Put reminders in your diary twelve and twenty-four months after those milestones.
Use both partners’ allowances
Transfers between spouses and civil partners happen at no gain/no loss for CGT. If only one partner owns the shares, you can gift enough to put each of you at five percent. Both of you then receive a separate £1 million BADR ceiling. A couple may therefore protect £2 million of gain at fourteen percent.
Keep the company trading
HMRC measures trading status in the round. Large cash piles, investment properties, or excessive bond portfolios tilt the scales. Strip out surplus funds well before the two-year window. Move buy-to-let assets into a separate vehicle. Log board minutes to evidence that the company’s main aim is trade, not investment.
Plan for dilution
Equity fundraising can drop a founder below five percent. Luckily, a “dilution election” freezes the gain to date, so the founder still claims BADR when the exit arrives. File the election within twelve months after the share issue. Speak with a tax adviser before the round closes; the paperwork cannot wait for completion.
Charge little or no rent
Owning the trading premises personally? You may secure BADR on the building too, as an “associated disposal,” if you sell the property alongside the shares or within three years. One catch: charging full commercial rent blocks relief on that property. Instead, charge a token rent or none, and document the arrangement.
Use EMI options for key staff
Enterprise Management Incentive (EMI) option shares need no five-percent threshold, only the twenty-four-month holding period (option grant to sale). Grant options as early as possible; the clock starts on the grant date, not on exercise. Employees feel ownership, and the entire team benefits when the exit arrives.
Pick the right completion date
Exchange contracts by 5 April 2026 to hold the fourteen-percent rate. Any later and you face eighteen percent. You must avoid contrived sign-and-complete schemes—HMRC looks for genuine commercial reasons. Still, a well-timed deal that closes days before the new tax year can lock in a saving worth six figures.
Step-by-step claim process
-
Calculate the gain. Deduct base cost, professional fees, and any allowable losses.
-
Tick the BADR box on your Self Assessment CGT pages. Enter the qualifying amount.
-
File on time. Claims ride on the tax return and must reach HMRC by 31 January in the second tax year after the sale. Sell on 30 June 2025? File by 31 January 2027.
-
Keep evidence. Hold share registers, board minutes, annual accounts, option agreements, and proof of trading activity for at least five years. HMRC can enquire.
A real-world example
Case study – Sarah’s software exit
Sarah founded Swift Task Ltd in July 2021, became a director the same day, and has always owned twenty percent of the ordinary shares. The company builds workflow apps, holds little cash, and owns no property. In March 2025 Sarah agrees to sell her shares to a listed buyer for a £1 million gain. These steps ensure the relief:
-
The company has traded for nearly four years, so the trading test passes.
-
Sarah held her shares and her office for more than twenty-four months.
-
Her stake exceeds five percent.
-
Exchange and completion take place on 31 March 2025—within the ten-percent era—after full commercial negotiations.
Sarah pays CGT of £100 000 (10 percent). Had she waited until August 2025, the tax rises to £140 000. A delay beyond April 2026 would cost her £240 000. Careful timing kept £140 000 in her hands.
Common trip-ups and how to dodge them
-
Earn-outs paid in buyer shares. Those new shares may not meet the two-year rule, so the deferred element fails BADR. Negotiate cash or loan-note alternatives if you can.
-
Long business cessations. If you stopped trading over three years ago, selling the remaining assets no longer counts. Restart trade or sell sooner.
-
Extended overseas breaks. Leaving the UK can break your employee status. Keep a formal director appointment and minutes that prove active involvement.
When to seek advice
Even straightforward exits involve legal terms, option pools, and property. A pre-sale “BADR health check” twelve months out can flag dilution risks, non-trading assets, or share-option errors. An experienced tax adviser will:
-
Map the share cap table against the five-percent tests.
-
Draft dilution elections.
-
Model sale dates against the sliding CGT rates.
-
Liaise with lawyers so the sale contract avoids clauses that turn capital into income.
Few founders enjoy tax-form detail; experts justify their fee in stress saved and cash retained.
Conclusion
Business Asset Disposal Relief remains a golden opportunity. Yes, the rate rises from ten to fourteen percent on 6 April 2025, yet fourteen still crushes the main twenty-four percent CGT rate. Meet the two-year tests, maintain a clean trading profile, and time your sale before April 2026. Spouses should share ownership; employees should receive early EMI options. Follow these steps and you keep up to £100 000 more per £1 million of gain—money you earned, money you deserve to keep.
