BADR 2026: Capital Gains Tax on UK Business Sales

Bottom line up front. Business Asset Disposal Relief applies a 14 percent capital gains tax rate to the first £1 million of lifetime qualifying gains on a UK business sale in 2026, with the balance taxed at 24 percent. The BADR rate is currently 14% (rising to 18% from 6 April 2026) on the first £1m of qualifying gains, the lifetime limit has been cut from £10m to £1m, the main CGT rate sits at 24%, and Employee Ownership Trust relief has been halved for disposals on or after 26 November 2025. The practical consequence for any owner planning an exit in the next twenty-four months is that headline valuation and tax route now have to be modelled together, on a like-for-like net-of-tax basis across every realistic structure, before a single conversation with a buyer or an adviser turns serious. Get that modelling wrong and you can leave 15 to 25% of net proceeds on the table, not because the buyer underpaid, but because the wrong route was chosen for the wrong reasons.

For 2026 exits the tax landscape is set: BADR at 14% on the first £1m of qualifying gains, rising to 18% from 6 April 2026, a main CGT rate of 24%, and EOT relief halved for disposals on or after 26 November 2025. Across 2,500+ UK SME business value appraisals at BusinessValuation.co.uk, the owners who bank the most are the ones who model these rates into their exit timetable early rather than discovering them in heads of terms.

This article is the practical, masterclass-length version of the conversation we have every week with owners of UK SMEs in the £1m to £50m turnover range. It is not tax advice for your specific situation. Your accountant and a CGT specialist must own the numbers for your facts. What it is, is the operating model an experienced UK SME valuer uses to frame the decision: how the reliefs interact, what has changed for 2026, why valuation has to come first, where the structural traps sit, and what an eighteen-month preparation programme actually looks like in calendar form.

If you are reading this with a likely sale in the next twenty-four months, work through it in order. The decisions are sequential. Get the gross valuation under each realistic route first. Layer in the post-tax model second. Choose the route third. Negotiate the deal fourth. Anyone trying to do those in a different order is, in our experience, almost always optimising the wrong variable.

The two analogies you need: surveyor's report and the gearbox

Two analogies make the BADR-and-valuation interaction intuitive. The first is the chartered surveyor's report on a house. A surveyor does not pluck a value out of the air; they measure the property, reference comparable sales, and produce a defensible range. Your business valuation is the same exercise: gross enterprise value before any tax layer is applied. The tax route is a separate calculation that determines how much of that gross number reaches your personal bank account. Surveying the house and choosing the mortgage product are different jobs done in a specific order; the price is established first, the financing follows.

The second analogy is the gearbox. A trade sale, a private-equity deal, a management buy-out, an Employee Ownership Trust and a family transfer are not the same gear. They use different multiples, different consideration mixes, different timing of cash, and different tax rates. Driving the wrong gear at the wrong speed wrecks the engine. In valuation terms, the wrong route burns 5 to 15 percentage points of net-of-tax proceeds, sometimes more, often invisibly to the seller until completion has happened and the cash arrives lower than expected. The discipline that protects you is to model every gear before you commit to one.

Where BADR sits in 2026

Business Asset Disposal Relief, the relief many owners still call Entrepreneurs' Relief, applies to qualifying gains on the disposal of all or part of a trading business, the assets of a trading business after cessation, or shares in a personal trading company. To qualify on a share sale, the seller must generally have been an officer or employee of the company, have held at least 5% of the ordinary share capital and voting rights, and have been entitled to at least 5% of distributable profits and assets on a winding up, for a continuous period of at least two years ending with the disposal.

The headline rate has moved sharply in successive Finance Acts. The relief was 10% for two decades; it stepped up to 14% in April 2025 and is legislated to rise to 18% from 6 April 2026. The lifetime limit was cut from £10m to £1m of qualifying gains per individual in March 2020 and has not been restored. The main CGT rate on share disposals above the BADR allowance sits at 24% for higher-rate taxpayers. The cumulative effect: an owner selling £5m of shares in 2026 keeps roughly 78p of every pound at the headline level, not the 90p the rule of thumb suggests. For a £10m gain the effective blended rate sits well above 20%, before any earn-out reclassification risk is layered in.

Each spouse or civil partner has their own £1m lifetime allowance and must independently meet the 5% personal-company and officer-or-employee tests. For couples who genuinely both work in the business and hold qualifying shares, that doubles the headline relief available, but only where the shareholding and employment history actually support the claim. Last-minute share transfers in the year before a sale almost never achieve the intended result; HMRC examine substance, not form, of the holding period.

What changed in November 2025: the EOT halving

The single biggest 2026 planning change is not BADR itself, it is the Employee Ownership Trust regime. For disposals on or after 26 November 2025, the previous 100% CGT relief on a qualifying EOT sale no longer applies in full. Under the revised rules, where the qualifying conditions are met and relief is claimed, 50% of the gain is treated as chargeable for CGT purposes and 50% may benefit from EOT relief, subject to the statutory conditions being satisfied and not breached during the disqualifying period (extended in the same package).

In rough numerical terms, an EOT sale that would have delivered an effective 0% rate on a £6m gain pre-November 2025 now delivers roughly 12% effective (50% chargeable at the main CGT rate, the other 50% relieved), before any vendor-loan interest and timing adjustments. That is still materially better than a trade-sale rate of around 22 to 24% blended, and substantially better than a sale taxed entirely at the main rate, but the gap between routes has narrowed. Owners modelling an EOT against a trade sale on pre-November 2025 assumptions are working with a number that no longer exists.

The package also tightened trustee independence rules, valuation evidence requirements, control tests and ongoing compliance for the disqualifying period. An EOT is no longer a documentation-light, tax-driven structure that can be built around an aspirational valuation. It is a regulated transaction in which trustee duty, market-value evidence and post-completion governance are policed actively, with retrospective clawback risk if the conditions are breached.

Why the valuation must come first, always

There is a permanent temptation to start with a tax route and back into a valuation. The order is wrong. The tax efficiency of any route is meaningless until you know the gross number it is being applied to. A trade sale at a strong strategic premium taxed at 22% can still net more than an EOT at 12% on a lower internal valuation, because the buyer set, the deal structure and the multiple are different across routes. A growing minority of owner-managed businesses do better post-tax through an EOT or MBO in 2026, but only after the gross number under each route has been honestly modelled.

A proper indicative valuation produces the gross number under each realistic route: trade buyer, private-equity or PE-backed consolidator, MBO funded by management plus debt, EOT funded by surplus cash plus vendor loan, and family transfer at market value with gift hold-over. The buyer profile, the multiple, the structural risk discounts and the consideration mix differ by route. From there your tax adviser models net proceeds; only then is it sensible to choose a direction and commission formal work such as an information memorandum, an EOT trustee report or an HMRC-aligned VAL231 for an internal share scheme.

Owners who skip the gross-valuation step almost always regret it. They either over-pay tax on a sale priced below what the strategic market would have borne, or they walk away from an EOT or MBO that would have been the better outcome, because they did not know the trade premium was thinner than they assumed.

The five exit routes, priced post-tax

There are five realistic exit routes for a profitable UK SME. Each comes with its own typical valuation premium or discount versus a 'clean' baseline, its own typical consideration mix, and its own effective tax rate when modelled honestly. The table below is calibrated to our aggregate UK SME transaction data; sector, size and structural quality move every number, but the relative ranking is robust.

Read across the row, not down a column. The strategic trade buyer pays the highest multiple and the highest tax rate, but front-loads the cash. The EOT pays a lower multiple at a lower effective rate, but back-loads the cash through a vendor loan repaid out of post-tax profits over five to nine years. The MBO sits in between. A family transfer using gift hold-over relief crystallises no tax at the point of transfer but defers the gain to the recipient. The right route is the one that wins on the post-tax net present value of cash to your personal account, weighted by certainty, not the one with the headline multiple or the headline rate.

Earn-outs, loan notes and the timing trap

Most trade and PE deals split consideration: cash at completion, deferred consideration, loan notes, rollover equity, and an earn-out tied to future performance. Each component is taxed differently and crystallises at a different time. The structural points routinely move the headline post-tax outcome by 10 to 20 percentage points and are decided at heads of terms, not at completion.

An earn-out is treated as further consideration for the shares if it is genuinely consideration for the shares. It can fall within BADR subject to the ascertainable / unascertainable distinction and the lifetime limit at the time the gain crystallises. An earn-out contingent on the seller's continued employment can be reclassified as employment income, taxed at marginal rates plus National Insurance, and the BADR benefit on that slice is lost. The single most common drafting failure we see is an earn-out hurdle that requires the seller to be employed at the measurement date; that one clause routinely costs sellers 10 percentage points of effective tax.

Loan notes can defer the gain but the BADR treatment depends on whether you elect to disapply the share-for-loan-note rollover. Without an election, the gain rolls into the notes and BADR is assessed on redemption at the rate and within the limit then prevailing, not today's. With an election, the gain crystallises now at today's rate. With the rate trajectory rising (14% in 2025/26, 18% from April 2026), the value of the election shifts year by year and is one of the highest-leverage decisions an adviser makes for you.

Rollover equity into the buyer's holding company is consideration in shares and does not trigger a chargeable disposal at completion. The gain attaches to the rollover shares and crystallises on their eventual disposal. Useful for deferring tax, painful if the buyer's subsequent equity story disappoints.

EOT as a 2026 alternative: the numbers that actually work

An EOT sale of a controlling interest, under the post-November 2025 rules, attracts effective tax of roughly 12% on the qualifying gain (50% chargeable at 24%, the other 50% relieved). The trust buys the shares at market value funded by a mixture of existing company cash, third-party debt where appropriate, and most commonly a vendor loan from the sellers repaid out of post-tax company profits over five to nine years.

Three things matter when comparing an EOT against a trade sale on an after-tax basis. First, the valuation: EOT valuations must be defensible to HMRC and to the trustees as not exceeding market value, which usually means a disciplined multiple of maintainable earnings rather than the strategic premium a synergistic trade buyer might pay. Second, the cash profile: trade sales typically pay a large lump sum at completion plus an earn-out; EOTs typically pay a smaller lump sum and a longer vendor loan that depends on the company's continued performance to service. Third, the qualitative weight: continuity for staff, retained client relationships, the legacy of the business, and the seller's ongoing role as a director during the disqualifying period.

The cross-over point in 2026 sits around a 25 to 35% trade-sale multiple premium. Below that premium, the EOT typically wins on net-of-tax NPV once the vendor-loan timing is risk-adjusted. Above it, the trade sale typically wins, particularly where the buyer is paying for synergies the EOT trustees cannot evidence. The only honest way to know which side of the line your business sits is to model both with the same disciplined assumptions.

The 18-month preparation blueprint

Preparation buys both gross-value uplift and tax-route optionality. The cost of preparation is trivial against the value it preserves: in our aggregate casework, owners who run this programme net 18 to 35% more cash than those who respond to an unsolicited approach without runway. Drawing from our aggregate transaction data at BusinessValuation.co.uk, here is the staged programme we run with owners eighteen to twenty-four months from a likely exit.

The two highest-leverage workstreams are 0 to 3 (the multi-route indicative and the tax model) and 6 to 9 (the structural mitigations that compress the discount a buyer would otherwise apply). Both are inexpensive. Skipping either is where owners lose six- and seven-figure sums quietly, between heads of terms and completion, in chips the buyer extracts because the structural evidence was not pre-built.

Anonymised case study: Yorkshire industrial services, £1.8m EBITDA

Drawing from our aggregate transaction data at BusinessValuation.co.uk, a representative Yorkshire industrial services business with maintainable EBITDA of £1.8m, net cash of £400k, two equal founder-shareholders both employed in the business for fifteen years, and a capable second-tier management team. An unsolicited trade approach arrived at 6.0x (EV £10.8m, equity £11.2m, with £7m cash at completion, £2m loan notes over three years, £2.2m earn-out over two years tied to EBITDA performance with a continued-employment hurdle).

On the unprepared trade route as offered, the net-of-tax outcome to the two sellers was modelled at £8.3m combined: BADR on the first £1m of gain each, main CGT rate on the balance, employment-income reclassification on roughly £1.5m of the earn-out because of the employment-hurdle drafting. That is an effective blended rate of 26%, a long way from the 10% rule of thumb each founder had carried in their head.

After a twelve-month preparation programme, the same business was re-marketed competitively. Three strategic bidders entered an auction, the multiple moved to 6.8x on a normalised EBITDA of £1.95m (EV £13.3m, equity £13.7m), the consideration mix moved to £10.5m cash at completion, £2m loan notes with election to disapply rollover (crystallising at the 14% / main-rate blend in the current year), and a £1.2m earn-out redrafted as ascertainable consideration with no employment hurdle. The net-of-tax outcome rose to £11.1m combined, an increase of £2.8m. An EOT alternative was modelled in parallel at 5.6x (EV £10.9m, equity £11.3m) with effective tax of 12%, producing £9.9m net on a back-loaded profile.

The trade route still won, but only after preparation. The unprepared trade sale netted less than the EOT alternative, which is exactly the trap the rule of thumb produces. The preparation cost: roughly £45k in advisory fees over twelve months. The uplift: £2.8m in cash to the founders.

What stays the same

Headline rates change. The core valuation discipline does not. Whichever route you choose, a buyer, a trustee, or HMRC will ask the same fundamental questions: what is the maintainable earnings figure, what is the right multiple given the risk profile, and what is the bridge from enterprise value to the cash that arrives in your personal account?

Get the gross number right under each realistic route, model the net under current and prospective rates, and only then choose. The 2026 BADR and EOT changes are not a reason to panic, they are a reason to plan with sharper numbers than you would have needed five years ago. Owners who do that work routinely tell us afterwards that the biggest benefit was not a higher number; it was the disappearance of the panic that surrounds an unsolicited approach when the work has been done in advance.

What to do in the next 90 days

If a sale is on your two-year horizon, three concrete actions in the next ninety days will pay off whatever the eventual rate turns out to be. First, commission an indicative valuation under at least three routes (trade, MBO, EOT) on the same set of assumptions; not a full report, a reasoned range. Second, ask your accountant to model net proceeds at three rate assumptions (current 14% BADR, the April 2026 18% rate, the main 24% CGT rate) across realistic deal structures (all-cash, cash plus earn-out, vendor loan with and without election). Third, review the personal-company tests for every shareholder so any restructuring needed to preserve BADR happens with months of runway, not weeks.

These three steps cost a small fraction of the gain at stake. They are the lowest-cost, highest-leverage moves in the entire exit toolkit, and they convert the most stressful conversation an owner-manager will ever have into a structured commercial decision driven by numbers, not by the timing of an unsolicited email.
