Selling Your Business: Structuring the Exit So You Keep More of It

Selling Your Business: Structuring the Exit So You Keep More of It

The answer, up front. Selling your business is not one decision — it is a sequence of them, and most of the tax is won or lost in the twelve months before completion, not at completion. Three levers do most of the work: your Business Asset Disposal Relief (BADR) — a lifetime £1m of gains taxed at a reduced rate that is rising (10% up to 5 April 2025, 14% for 2025/26, 18% from 6 April 2026); when the deal completes relative to the tax year and that rate path; and where the proceeds land — a pound moved into a pension by the company before the sale is taxed very differently from a pound taken as cash after it. The owners who keep the most are not the ones who negotiate the highest headline price. They are the ones who structured the sale before the buyer ever appeared.

You spend years building the business and, often, a matter of weeks deciding how to sell it. That asymmetry is where money leaks. Here is how to think about the exit as a professional would: fix the relief, time the completion, structure the consideration, pre-load the pension, and plan the landing before the "sudden liquidity" arrives. Four moves decide the outcome.

The one idea most people miss

A sale price is not what you keep. The number that matters is the net-of-tax, net-of-adviser, after-the-earn-out-actually-pays figure that lands in your name — and that number is set by structure, not by the headline. Two owners can sell identical companies for £2m and walk away £150,000 apart purely on how the deal was papered and when it closed.

The professional instinct is to treat the exit as an 18-month project with a tax calendar, not an event triggered by an approach. Once heads of terms are signed and the completion date is set, most of your levers are already gone. The planning window is before the process starts — while you still control the timing, the share structure, and where the money can go.

A decision framework for an exit

1. Fix your Business Asset Disposal Relief — and know it is shrinking. BADR (the relief formerly called Entrepreneurs' Relief) gives you a reduced Capital Gains Tax rate on up to £1m of qualifying gains across your lifetime. To qualify you generally need, for at least two years before sale, to hold 5% or more of the ordinary shares and voting rights in a trading company that is your personal company, and be an officer or employee. The catch is the rate is on an escalator: 10% until 5 April 2025, 14% for the 2025/26 tax year, and 18% from 6 April 2026 — converging toward the main CGT rate of 24%. Gains above the £1m lifetime cap are taxed at 24% regardless. Two years of qualifying ownership is not something you can create the week before you sell — check it early, and check every co-shareholder (a spouse with their own 5% can bring a second £1m lifetime allowance into the family).

<figcaptionOn the first £1m of qualifying gains, the same sale costs £80,000 more in tax after April 2026 than it did before April 2025 — purely on the completion date. Timing is not a detail; it is a line item.<span class="chart-note"<bFact:</b the BADR rate is 10% to 5 April 2025, 14% in 2025/26, and 18% from 6 April 2026; the £1m is a lifetime cap. <bAssumption:</b a single £1m qualifying gain fully within BADR; gains above £1m are taxed at 24%.</span</figcaption </figure

2. Time the completion around the tax year — and the rate path. Capital Gains Tax is charged in the tax year the disposal completes (broadly, unconditional exchange of contracts). Completing on 4 April versus 6 April moves the whole gain by a full tax year — which matters when the BADR rate is stepping up, when you want to use two years' worth of anything, or when you can split a disposal so a spouse's separate allowances and BADR band are used. Never let a completion date be set by the buyer's convenience alone; it is one of the few tax levers still in your hands late in the process.

3. Structure the consideration — earn-outs are where relief quietly dies. Few businesses sell for a single cash cheque. Deferred consideration and earn-outs (part of the price contingent on future performance) are normal — and a trap. An earn-out right can itself be a separate asset that does not qualify for BADR, so a slice of your price that felt like it was covered by the relief can be taxed at the full 24% when it pays years later. How the earn-out is drafted — cash versus loan notes, the "Marren v Ingles" valuation of the right at completion, whether you elect to be taxed up front — changes the bill materially. This is drafting done before signing, not a problem to notice when the cash arrives.

4. Pre-load the pension from the company before you sell. The most efficient pound at an exit is often the one that never becomes sale proceeds at all. An employer pension contribution made by the company before completion is generally deductible against corporation tax, carries no National Insurance, and is not income tax on you — it simply moves value from a taxable sale into a tax-advantaged wrapper. The annual allowance is £60,000, and unused allowance from the previous three tax years can often be carried forward — potentially well over £100,000 in a single year if the company has the profits to fund it. Done in the run-up to a sale, this can shelter a large slice of value that would otherwise be taxed on the way out.

A worked mini-example

Priya owns 100% of a trading company and agrees to sell for a £2m gain. She has never used her BADR.

- The relief: the first £1m of her gain uses BADR. In 2025/26 that is 14% = £140,000. Left to 2026/27 it would be 18% = £180,000 — a £40,000 swing on timing alone. - Above the cap: the remaining £1m is taxed at 24% = £240,000, with or without BADR. - The pension move: in the year before sale, the company makes a £100,000 employer pension contribution for her (using the annual allowance plus carry-forward). That is £100,000 of value moved into her pension — corporation-tax deductible, no NI, no income tax now — instead of sitting inside a company she is about to sell. - Her spouse: he has held a genuine 5% qualifying stake for over two years, so his own £1m BADR band shelters part of the gain the family would otherwise pay 24% on. - The landing: rather than investing £1.5m of net cash the week it arrives, she parks it in safe, boring accounts and places it deliberately over the following year.

The company sold for the same £2m either way. The structure and the timing — BADR band, completion year, the spouse's stake, the pre-sale pension, the calm landing — changed what Priya kept by a six-figure sum.

The "sudden liquidity" trap

The day the money lands is the most dangerous day of the whole exit. You go from an illiquid, familiar asset you understood to a large, liquid sum that everyone has an opinion about — and the pressure to do something clever is immense. It is the same trap as any windfall, at a larger scale: the cost of parking the proceeds somewhere safe for three months is trivial; the cost of a rushed, permanent decision made while you are still adjusting to the number is not. Slow down. Preserve optionality. Place it once you can think.

Common mistakes

- Starting the sale before the tax planning. Once heads of terms are signed, the levers are mostly gone. - Assuming BADR covers the whole gain. It caps at £1m of lifetime gains; the rest is 24%. - Ignoring the rate escalator — 10% to 14% to 18% — and letting the buyer set a completion date across a tax-year line. - Not checking the two-year qualifying conditions for you and every co-shareholder early enough to fix them. - Treating an earn-out as "just part of the price" without checking whether the right itself qualifies for relief. - Skipping the pre-sale employer pension contribution — often the single most efficient pound at an exit. - Investing the whole proceeds the week they arrive, under pressure, before the plan exists.

A short pre-sale checklist

- [ ] Confirm BADR eligibility — 5%+ holding, trading company, officer/employee, two years — for you and any co-shareholders. - [ ] Map the gain against the £1m lifetime cap and the current rate for your likely completion year. - [ ] Decide the completion date deliberately relative to the tax year and the rate path. - [ ] Have the earn-out / deferred consideration structured and its BADR treatment checked before signing. - [ ] Make the employer pension contribution (annual allowance + carry-forward) while the company still can. - [ ] Use a spouse's separate BADR band and allowances where holdings are genuine. - [ ] Plan the landing — park the proceeds safely; place them over the following year, not the following week.

Selling a business rewards the people who treat the exit as the last, most deliberate stage of building it — not as an afterthought bolted on when a buyer knocks. What you keep is decided before the deal, not at it.
