Sell Smart: Lock in 10% With Business Asset Disposal Relief

You spend years turning chaos into a company people trust. Then the buyer slides a term sheet across the table, and the number looks good. Here’s what nobody tells you: what you keep often depends less on the headline price and more on how you structure the exit.

A founder I worked with sold for a number that should have set them up for life. Same business, same buyer, same price, two very different tax bills because of choices made months earlier. One path unlocked Business Asset Disposal Relief. The other didn’t. The gap was six figures.

Why this matters before you sign anything

You get one clean shot at selling right. Miss the relief, and you pay for a chunk of your future with money that could have stayed in your pocket.

Here’s the truth: Business Asset Disposal Relief (BADR) isn’t a form you file at the end. It’s a position you build long before the buyer shows up. If you wait until due diligence to think about it, you’re already on the back foot.

Ask yourself a hard question: if you had to prove tomorrow that you qualify, could you do it without scrambling through inboxes and folders? If not, fix it now.

What BADR really gives you

In plain English: if you qualify, you pay 10% capital gains tax on up to a £1,000,000 lifetime limit of qualifying gains when you sell. Not income tax. Not 20% CGT. Ten percent on qualifying gains. That single digit can make hard years feel worth it.

It used to be called Entrepreneurs’ Relief. The name changed. The heart didn’t. It rewards people who build and sell real trading businesses.

There’s a catch: you have to tick the right boxes for a sustained period, usually two years before the sale, and you have to sell the right thing in the right way. That’s where many founders slip.

Who qualifies, the simple version

Think in three pillars: your role, your stake, your business.

• Your role: You’re an employee or director for at least two years up to sale. Modest pay is fine. What matters is you’re on the inside, not a passive investor.
• Your stake: You hold at least 5% of ordinary shares and voting rights for those two years. EMI option holders can still qualify once options are exercised, even under 5%, if the options were granted under an approved EMI scheme and the two-year clock runs from grant.
• Your business: The company is a trading company, not mainly an investment vehicle. Sole traders and partners can also qualify on selling the whole business or a distinct part.

Own the premises personally that the business uses? Relief may be possible on an associated disposal, but only if you sell it with or around the time you sell the business, and charging full market rent for years can restrict relief. A short chat with a sharp adviser here can save a fortune.

Deal shape that protects the relief

Buyers love asset sales. You might need a share sale. It matters. Selling shares in your trading company is the cleanest route to BADR. An asset sale can work for sole traders or partnerships, but selling only assets out of a company often won’t give you BADR on your personal gain.

Guard your 5%. If you dip under because of a funding round, the two-year clock can break. UK dilution elections can bank your relief up to the point of dilution, and defer the tax until you actually sell. They are not automatic, file them when the round happens, not when you’re packing boxes.

Deal terms bite too. Earn-outs, deferred consideration, and loan notes are normal, but they can change when gains are taxed and whether relief applies to each piece. Keep the 10% outcome front and centre and run the numbers before you agree.

Prep moves you can make this month

You don’t need a fifty-page playbook. You need clean facts, simple steps, and early action.

• Confirm your timeline: Are you at or past the two-year mark for your role and your shares? If not, plan for it.
• Clean the cap table: Spot anything that could knock you under 5%, preference stacks, convertibles, unexercised options, planned grants.
• Prove trading status: Keep crisp evidence, customer contracts, invoices, payroll, active operations.
• Gather documents: EMI grant paperwork, board minutes, share certificates, employment/director letters, property use and rent records if you own premises personally.
• Model the deal: Headline price minus costs. Compare 10% with BADR against standard CGT. See how share sale vs asset sale, earn-outs, and loan notes change your net.

This is what separates calm closers from frantic sellers. They know the rules, shape the deal, and make the buyer fit it, not the other way around.

Numbers that change how you feel about the offer

Sell your shares with a £1.2m gain after costs. With BADR, the first £1m is at 10% (£100,000). The remaining £200,000 is typically at 20% (£40,000). Total: £140,000.

No relief? Assume 20% across the full £1.2m: £240,000. Same headline price. £100,000 swings back into your pocket. That’s your first year of freedom, your kids’ school fees, or the runway for your next play.

The point isn’t the exact bracket this year. The point is control. Structure right, and you control your outcome.

The human side of a clean exit

You didn’t build this thing to lose sleep at the finish line. Most regret comes from avoidable surprises, a forgotten option agreement, a director appointment never filed, a share transfer never stamped. Tiny misses. Huge consequences.

Build a one-page checklist. Share it with your accountant, your lawyer, your CFO. Put dates next to each item. When the buyer asks for proof, you don’t scramble, you click send.

Ask yourself: what will make me proud of how I sell, not just what I sell for?

Key takeaway

You don’t win the tax game on completion day. You win it in the quiet months before anyone knows you’re selling. BADR rewards preparation, not luck.
