The headline price on an accountancy practice sale is the number that gets talked about. The net cash that arrives in the seller's bank account is the number that matters. Between the two sit the tax decisions, taken in the eighteen months before completion and at completion itself, that determine how much of the headline actually survives. This article walks through the structures that drive that difference for UK chartered principals selling small practices in 2026, with worked examples at three book sizes.
The content below is general guidance only. Tax legislation changes, rates and thresholds drift between Budgets and Finance Acts, and the right answer for any individual seller depends on personal income position, family circumstances, existing pension wealth, and the buyer's own preferences. Take independent tax advice from an adviser with no contingent interest in the deal completing. The cost of that advice is trivial compared with the difference between a well structured and a poorly structured exit.
The two routes: asset sale and share sale
Almost every UK accountancy practice sale resolves into one of two transaction structures. The seller sells the assets of the practice (the client list, work in progress, goodwill, fixed assets, and so on), or the seller sells the shares in the company that owns those assets. The choice determines how the seller is taxed, how the buyer is taxed, and what each side carries forward in terms of liabilities.
The asset sale, sometimes called a trade and assets sale, is the more common structure for small practice deals. The buyer takes specifically identified assets and assumes specifically identified liabilities. Anything not listed in the sale agreement stays with the seller's company. This is attractive to buyers because the risk of inheriting historic problems (a forgotten contingent liability, a dormant client complaint, a PII matter) is contained.
The share sale transfers ownership of the company itself. The buyer takes everything inside the company, the good and the bad. Sellers prefer this route because it is generally more tax-efficient on the personal side, and because it is a clean break: once the shares have transferred, the company and all its history is the buyer's problem. Buyers are more cautious because they assume historic liabilities, which is why share sales involve more extensive warranties, indemnities, and sometimes escrow arrangements.
The choice of route is rarely a matter of pure preference. It is the outcome of a negotiation in which the seller's tax position and the buyer's risk appetite are both pulling. The headline multiple offered on the two routes is often slightly different, with the asset sale carrying a marginal premium because the buyer is taking less risk.
Business Asset Disposal Relief: the central question for the seller
For a chartered principal selling shares in their own trading company, the most consequential tax provision is Business Asset Disposal Relief, formerly known as Entrepreneurs' Relief. BADR reduces the capital gains tax rate on qualifying gains to a preferential rate up to a lifetime limit per individual. The rate was 10 per cent up to 5 April 2025, 14 per cent for disposals between 6 April 2025 and 5 April 2026, and 18 per cent for disposals from 6 April 2026 onward. The lifetime limit is £1m, having been reduced from £10m in 2020. Both the rate and the limit have been subject to policy change over the past several Budgets, so the current position should be checked at the time of any actual transaction.
Qualifying conditions, broadly, require that the seller has held at least 5 per cent of the ordinary share capital and voting rights in the company for at least the two years before disposal, that the company is the seller's personal company (which the 5 per cent and voting test largely establish), that the company has been a trading company throughout that period, and that the seller has been an officer or employee. For a sole-principal incorporated practice, all four conditions are typically met without difficulty. For a recently restructured group, or for a company with significant non-trading activities (large investment portfolios, surplus cash beyond working capital, residential property), the trading company test can become contentious.
The practical result is that a qualifying share sale by a sole principal can convert what would otherwise be a 24 per cent CGT charge into an 18 per cent charge on the first £1m of lifetime gains (rate as at 6 April 2026). On a £500k goodwill gain, the difference between qualifying and not qualifying for BADR is in the order of £30k of tax. Smaller than it was when BADR was at 10 per cent, but still a deal-shaping number, and significantly larger if the gain runs up to or above the lifetime limit.
It also explains why, for share sales, sellers will frequently instruct their advisers to confirm BADR eligibility well in advance of completion. A reorganisation that makes the company non-qualifying in the two years before sale (for example, accumulating excess cash that fails the trading company test, or transferring shares to a non-employee family member) can knock out the relief. Once knocked out, the two-year clock has to start again.
The asset sale on the seller's side
An asset sale of a sole-principal practice owned through a limited company involves two distinct tax events. The company sells the assets and pays corporation tax on the gain. The company then distributes the after-tax proceeds to the shareholder, who pays personal tax on the distribution.
The corporate-level gain is principally a goodwill gain. For most small practices, the asset value is overwhelmingly goodwill (the embedded value of the client relationships and recurring revenue), with a small element of fixed assets and work in progress. The gain on goodwill in the company's hands is taxed at the prevailing main rate of corporation tax, which has been 25 per cent for companies with profits over the upper limit. For smaller deals where the company's overall profits in the year of sale fall in the marginal relief band, an effective rate between 19 per cent and 25 per cent can apply.
Once corporation tax has been paid on the gain, the after-tax proceeds sit in the company. The shareholder then needs to extract them. The two routes are dividend (taxed at dividend rates, with the upper rate being the most likely to apply given a typical sale year income) and capital distribution on company liquidation, which is potentially eligible for CGT treatment and, if the conditions are met, BADR at the preferential rate up to the lifetime limit.
The members' voluntary liquidation route is the standard exit for a sole-principal company after an asset sale. Properly handled, with no continuing trading activity in the company and no targeted anti-avoidance issues, the capital distribution can qualify for BADR and the shareholder pays the preferential rate on the distributed proceeds, after the company has already paid corporation tax on the underlying gain.
The combined effective rate on an asset sale through a company, with MVL extraction at BADR rates, is usually around 35 to 40 per cent of the gross gain, depending on rates and on how much of the gain falls within the BADR lifetime limit. This compares with 18 per cent on a direct share sale qualifying for BADR (rate from 6 April 2026). The difference is the corporation tax layer, and it explains why sellers usually prefer share sale where it is structurally available.
The share sale on the seller's side
A share sale of the company by the principal shareholder is taxed once, on the personal CGT side, at rates determined by the seller's other income for the year and by BADR availability. For a qualifying disposal up to the lifetime limit, the rate is 18 per cent (from 6 April 2026). Above the lifetime limit, the rate reverts to the standard CGT rate, currently 24 per cent.
The simplicity of the share sale tax outcome is its principal attraction. The seller receives the proceeds (less the deferred portion, if any), reports the gain on the relevant Self Assessment return, and pays the CGT charge by the standard payment date. There is no corporate-level tax layer, no extraction question, no MVL to organise.
The buyer, however, takes everything inside the company, which is why the warranty and indemnity package is more extensive. Where the buyer wants belt and braces, an escrow holding back a portion of the consideration for a defined period is common. Sellers should expect this, price it into the deal, and not be surprised when it is proposed.
The buyer's preference and goodwill amortisation
Buyers have their own tax considerations and they pull in the opposite direction to the seller's. From the buyer's side, the key question is whether the goodwill being acquired generates a deduction for tax purposes after acquisition.
For corporate buyers acquiring goodwill in an asset sale after April 2019, the position has been that goodwill amortisation is, broadly, deductible for corporation tax purposes against the buyer's profits, subject to specific conditions and at a fixed rate, where the goodwill was acquired alongside qualifying intellectual property or where the seller is unrelated. This is materially more attractive to buyers than the position between 2015 and 2019, when relief was effectively withdrawn, and considerably more attractive than the share sale case where the buyer takes ownership of an existing goodwill asset that has typically been generated internally and carries no base cost for amortisation purposes.
The result is that, all else equal, a corporate buyer will often prefer an asset sale because the post-acquisition tax cost of carrying the goodwill is lower. This is why the seller's preference for share sale (to access BADR cleanly) and the buyer's preference for asset sale (to access amortisation relief) are usually in tension. The negotiated outcome reflects the relative bargaining strength of the two sides and the gap each side is willing to bridge with a price adjustment.
Specific rules around connected parties, related-party intellectual property, and pre-2002 goodwill all bear on the position. The general direction of travel is favourable for asset-sale buyers in the current rules; the seller's adviser should confirm the current state of the regime before assuming.
VAT and the TOGC
The default position on the sale of business assets is that VAT is chargeable on the sale at the standard rate. This is a cash flow problem for the buyer (who has to fund the VAT and recover it on the next return) and an administrative problem for the seller (who has to charge it, account for it, and deal with the buyer's queries).
The Transfer of a Going Concern provisions allow the sale of a business to be treated as outside the scope of VAT where specific conditions are met. The principal conditions are that the buyer is, or becomes, VAT-registered; that the buyer intends to use the assets to carry on the same kind of business; and that there is no significant break in the business. For an accountancy practice sale where the buyer is a VAT-registered chartered firm intending to continue running the acquired client portfolio, all three conditions are typically met. The transaction is then outside the scope of VAT and no VAT is charged.
The TOGC analysis should be confirmed before completion, with the position properly reflected in the sale documentation. Mistakes (charging VAT when TOGC applies, or not charging VAT when it should be charged) are correctable but inconvenient.
Stamp duty and stamp duty reserve tax
The asset sale of a practice is generally outside the stamp duty net because the assets being transferred (goodwill, client lists, work in progress, fixed assets) are not chargeable assets for stamp duty purposes. Land and buildings, if any are included, attract Stamp Duty Land Tax in the normal way.
The share sale of a private company attracts stamp duty at 0.5 per cent of the consideration, payable by the buyer. On a £500k share sale this is £2,500. It is not a deal-shaping number but it is a real cost to the buyer and it is sometimes used as a small bargaining chip.
Pension contributions in the run-up to sale
For the sole principal trading through a limited company, the two tax years before completion are an opportunity to convert taxable corporate profits into tax-protected pension wealth. The mechanic is straightforward. The company makes employer pension contributions on behalf of the principal, the contributions are deductible against corporation tax (so they reduce the corporate profits that would otherwise be taxed at the prevailing rate), and the contributions accumulate inside the principal's pension wrapper free of further tax until drawn.
The annual allowance limits the amount that can be contributed in a tax year without incurring the annual allowance charge. The standard allowance has been £60,000 in recent rules, with an increased ceiling that may apply where carry-forward from the three prior years is available and where the individual has been a member of a registered pension scheme in those years. For a principal who has under-contributed in the prior three years, total contributions of £200,000 or more in a single year are achievable using carry-forward.
The tapered annual allowance applies for high earners and reduces the standard allowance by £1 for every £2 of adjusted income over the threshold, down to a floor. In the year of sale, the seller's income may be raised by sale-related receipts, so the tapering position needs to be modelled carefully. The interaction between the sale receipt, the company's bonus or salary policy in the run-up, and the pension contribution strategy is a calculation that benefits from being run by a tax adviser with the actual numbers, not from rules of thumb.
Anti-forestalling rules apply in periods around significant policy changes (for example, around historic adjustments to the lifetime allowance) to prevent contributions made in anticipation of a rule change from securing the old, more favourable treatment. The current position should be confirmed at the time. The general principle that pre-completion pension contributions are tax-efficient is durable; the specific limits and tapering rules drift with policy.
The lifetime allowance regime has been through significant change in recent years, with the historic limit having been removed and replaced with limits on tax-free lump sum entitlements and on certain death benefit treatments. This is precisely the area where time-limited references in this article are most likely to be out of date by the time you read it. Confirm the current position with your adviser.
Worked example one: £350k GRF book, sole principal, incorporated practice
Assume a general practice with £350k recurring fees, owned by a sole principal through a limited company with no significant non-trading assets and no group structure. The principal has held the company for ten years, has worked in it throughout, and has a clean BADR qualification position. The company has approximately £40k of net working capital and £20k of fixed assets at completion.
The headline acquisition price is around 1.05x GRF, so £367,500 of goodwill plus £20k of fixed assets, totalling roughly £387,500 of consideration. The numbers below are illustrative, ignore stamp duty and small balance sheet items, and assume current rates that may have moved.
Asset sale route: the company recognises a £367,500 gain on goodwill (assume nil base cost), pays corporation tax at the prevailing main rate on that gain (using 25 per cent for illustration: £91,875), leaving £275,625 of after-tax goodwill proceeds plus £20k of fixed asset proceeds (broadly tax-neutral if at book value). Combined with existing distributable reserves, the company then enters MVL. The capital distribution to the shareholder is, broadly, the company's net assets at the time of liquidation. Assuming the BADR conditions are satisfied and the lifetime limit has not been used, the shareholder pays 18 per cent CGT on the gain, which on a notional £350k distribution is roughly £63k. Total tax cost on the route: around £155k. Seller's net: around £232k.
Share sale route: the shareholder sells the shares for £387,500. Assuming a small base cost in the shares (typically the original subscription price, often nominal) and BADR qualification in full, CGT at 18 per cent is roughly £69k. Total tax cost on the route: around £69k. Seller's net: around £318k.
The difference between the two routes on this size of book is, in this illustration, around £89k of tax: a meaningful number on a deal of this scale. The share sale wins on the seller's tax position by a wide margin. Whether the buyer accepts the share sale at this size depends on the buyer's risk appetite for legacy liabilities and on the warranty package available.
Worked example two: £500k GRF book, sole principal, incorporated practice
Same assumptions, scaled up. Headline acquisition price around 1.10x GRF, so £550k of goodwill plus £25k of fixed assets, totalling roughly £575k.
Asset sale route: corporate gain on goodwill of £550k, corporation tax at 25 per cent of around £137k. After-tax goodwill proceeds of £413k plus fixed asset proceeds. MVL distribution to the shareholder, BADR at 18 per cent on the assumed £500k distribution, CGT of roughly £90k. Total tax cost: around £227k. Seller's net: around £348k.
Share sale route: shareholder sells shares for £575k. BADR caps at the £1m lifetime limit, comfortably above this transaction. CGT at 18 per cent is roughly £104k. Seller's net: around £471k.
The gap widens to around £130k of tax difference between the routes. On a half-million pound book, this is the difference between a comfortable retirement and a more comfortable one.
Worked example three: £750k GRF book, sole principal, incorporated practice
Same assumptions, scaled up further. Headline acquisition price around 1.15x GRF for a higher-quality book at this scale, so £862.5k of goodwill plus £30k of fixed assets, totalling roughly £892k.
Asset sale route: corporate gain on goodwill of £862.5k, corporation tax at 25 per cent of around £216k. After-tax goodwill proceeds of £647k. MVL distribution. BADR available on the first £1m of lifetime gains, so the £750k or so of capital distribution falls within the limit. CGT at 18 per cent on the distribution is roughly £135k. Total tax cost: around £351k. Seller's net: around £541k.
Share sale route: shareholder sells shares for £892k. The gain falls within the BADR lifetime limit (assuming the limit is unused). CGT at 18 per cent is roughly £161k. Seller's net: around £731k.
The gap at this scale is around £190k of tax. Above the BADR lifetime limit, the share sale advantage continues but at the standard CGT rate rather than the preferential one, which narrows the differential.
For a principal who has previously used some of the BADR lifetime limit on a prior business sale, the calculation needs to be re-run. For a principal whose income in the sale year takes them into the additional rate band, the marginal CGT rate above the BADR threshold may apply. The numbers above are illustrative for the unencumbered case.
The combined picture: pension contributions plus share sale
The most tax-efficient overall structure for a sole-principal incorporated practice, in current rules and where the buyer agrees to the share sale, tends to be a combination. The two tax years before completion are used to make the largest sustainable employer pension contributions out of corporate profits. This reduces the corporation tax burden in those years and accumulates pension wealth at full tax efficiency. Then the share sale itself is structured to qualify for BADR and the gain is taxed at the preferential rate on the personal side.
The combined effect, on a £500k book, can be in the region of £150k to £200k of additional retained value compared with a poorly planned asset sale and dividend extraction. The work of capturing this is done in the eighteen months before completion, not on the day. The principal who starts thinking about exit two years before is in a meaningfully different position from the principal who decides in March that they want out by the end of the calendar year.
What the buyer side looks like at Jack Ross
From our side of the table, we will engage on either route. Asset sale gives us a cleaner risk position and the post-completion goodwill amortisation benefit, and we will price marginally more attractively for it. Share sale costs us more in due diligence and in the warranty package, and we will price it slightly more conservatively. Either way, we expect the seller to take independent tax advice, we expect the structure decision to be taken on the seller's side, and we will not push a structure that worsens the seller's tax outcome unless the offsetting price difference is acceptable to the seller.
For most sole-principal practices in the £350k to £750k range, the share sale, BADR-qualifying, with pension preparation in the prior two years, is the structure that delivers the most net value to the seller. We will say so when asked, with the caveat that we are the buyer, not the seller's adviser, and the seller's own tax adviser should be the one making the final call.

Closing caveat
Tax legislation drifts. Rates change. Reliefs are restricted. The lifetime allowance regime has changed twice in the past five years. BADR has had its lifetime limit reduced from £10m to £1m, and its rate stepped from 10 per cent to 14 per cent and then to 18 per cent across the past two tax years. The annual pension allowance has moved repeatedly. Any specific number in this article should be checked at the time of any actual transaction, both with HMRC's published guidance and with a qualified tax adviser. The structures and the directional reasoning are durable; the precise rates and thresholds are not. This article was reviewed in May 2026.
This is general guidance only and does not constitute tax advice. Your individual circumstances may produce different outcomes. Take independent advice from a tax adviser with no contingent interest in the deal completing.
