Business Asset Disposal Relief: What Sellers Need to Know

Business Asset Disposal Relief (BADR) charges capital gains tax at 18 per cent on qualifying business disposals made on or after 6 April 2026, subject to a lifetime limit of £1 million of qualifying gains per individual. Whether a seller actually qualifies is decided by legal facts rather than by anything that happens in the tax return: the class of shares held, what the articles of association say about votes and distributions, who is named in the register of members and from when, and what the company has genuinely been doing for the two years before completion.

That is why this article is written from the legal side. We are commercial solicitors, not tax advisers, and nothing here is tax advice. What we can set out is the statutory framework a seller has to satisfy, how the structure of a deal makes those conditions easier or harder to meet, and the corporate housekeeping that quietly destroys an otherwise good claim. Every seller should confirm their own position, and the actual numbers, with their accountant or tax adviser before signing anything.

All rates, thresholds and dates in this article were checked against GOV.UK, HMRC’s Capital Gains Manual and the Taxation of Chargeable Gains Act 1992 as in force on 6 October 2026. Capital gains tax rates and reliefs are changed at Budgets, sometimes with immediate effect, so treat any figure in any article, including this one, as needing a fresh check on the day it matters.

The rate, the limit and the date each applies from

The relief does not exempt a gain. It charges the qualifying part of the gain at a lower, flat rate of capital gains tax. That rate has risen twice in two years, so the date of disposal decides the rate, not the date the money is received.

The lifetime limit is £1 million of qualifying gains per individual, set by section 169N(4) and (4A) of the Taxation of Chargeable Gains Act 1992. It is cumulative across every claim a person ever makes, not an allowance that refreshes each tax year. Gains above the limit fall back to the ordinary capital gains tax rates, which for disposals from 30 October 2024 are 24 per cent for higher and additional rate taxpayers and 18 per cent within the basic rate band. The separate annual exempt amount is £3,000.

There is a practical point hiding in that table for owner-managed businesses. The gap between the relieved rate and the main rate is now 6 percentage points rather than the 14 it once was, which means BADR is no longer the thing a deal should be bent out of shape to chase. It is worth qualifying for, but it is rarely worth accepting a materially worse commercial structure to protect. That is a judgement to make with your accountant and your solicitor together.

The three routes into the relief

The legislation does not have a single eligibility test. It has three distinct categories of qualifying disposal, each with its own conditions, and sellers frequently assume they are in one when they are actually in another.

1. Sole traders and partners disposing of a business

A sole trader or partner qualifies on a disposal of the whole or part of the business, provided they owned the business throughout the two years ending with the date of disposal. If the business has ceased rather than been sold, the two year ownership period runs to the date the business stopped, and the assets must then be disposed of within three years of cessation.

A trap worth knowing: selling individual assets out of a continuing sole trade is not a disposal of part of a business. The courts and HMRC both treat the sale of assets as something different from the sale of a definable part of the business as a going concern, and getting that wrong is one of the more common reasons a claim is refused.

2. Shareholders disposing of shares or securities

This is the route most owner-managed company sellers are on. For at least two years ending with the date of disposal, all of the following must be true:

• the company is the seller’s personal company (the 5 per cent tests, covered in detail below);
• the company is a trading company, or the holding company of a trading group; and
• the seller is an officer or employee of the company, or of a company in the same trading group.

Where the company has stopped trading, the same two year test applies up to the date trading stopped, and the shares must be sold within three years of that date.

Shares acquired through an Enterprise Management Incentive (EMI) option sit on a modified version of this route. The 5 per cent personal company tests do not apply. Instead the shares must have been acquired on or after 6 April 2013, the option must have been granted at least two years before the disposal, and the trading company and officer or employee conditions must be met throughout that two year period.

3. Associated disposals

Owner-managers often hold the trading premises personally rather than in the company. Section 169K allows relief on the sale of such an asset, but only as a companion to a qualifying disposal of the business or shares, and the conditions are strict. The seller must dispose of at least a 5 per cent interest in the partnership, or at least 5 per cent of the company’s ordinary share capital in their personal company, the asset disposal must form part of their genuine withdrawal from the business, the asset must have been in business use throughout the two years ending with the earlier of the material disposal or cessation, and the seller must have owned the asset throughout the three years ending with its disposal.

Two further restrictions catch people out. There must be no arrangements in place for the seller or a connected person to buy back into the partnership or company, which is why a sale with a rollover equity stake can fail this limb. And under section 169P, if rent was charged for the asset, relief is restricted to a just and reasonable proportion, measured by how far the rent fell short of an open market rent. A seller who has been charging the company a full commercial rent for the premises may get no associated disposal relief at all.

The personal company test: where most share sale claims are won or lost

Section 169S(3) defines a personal company. The seller must hold at least 5 per cent of the ordinary share capital, and by virtue of that holding be able to exercise at least 5 per cent of the voting rights. On top of that, one of two further entitlement tests must be met:

• The distribution and winding up test. By virtue of that holding, the individual is beneficially entitled to at least 5 per cent of the profits available for distribution to equity holders, and on a winding up would be beneficially entitled to at least 5 per cent of the assets so available. Both halves must be satisfied.
• The proceeds test. On a notional disposal of the whole of the company’s ordinary share capital, the individual would be beneficially entitled to at least 5 per cent of the proceeds. This alternative was added to help holders of shares whose economic rights do not track their percentage holding.

Three things in that wording do real damage in practice. First, the voting rights and the economic entitlement must both flow from the shareholding itself, not from a separate contract. A shareholders’ agreement that gives someone a veto or a profit share does not fix a share class that carries no votes. If the rights are not in the shares, review the articles and the share class, not the side agreement. Our shareholders’ agreements team deals with this distinction constantly.

Second, the entitlement tests import a modified version of the equity holder rules in Chapter 6 of Part 5 of the Corporation Tax Act 2010. Those rules look through the labels on a share class to its actual economic rights. A class described as “ordinary” in the articles can still fail, and a class that looks restricted can sometimes pass. This is the single most technical part of the regime and it needs a proper reading of the articles rather than an assumption.

Third, the proceeds test is applied on statutory assumptions: the whole ordinary share capital is treated as disposed of at market value on the final day of the relevant period, the entitlement is the amount it would be reasonable to expect having regard to all the circumstances, and the effect of any avoidance arrangements is ignored. Arrangements whose main purpose, or one of whose main purposes, is to make the Chapter apply or not apply are disregarded entirely.

Shares held jointly are apportioned by value, so joint holdings are treated as a proportionate sole holding for the 5 per cent tests. And if a shareholding is diluted below 5 per cent by a new issue of shares, GOV.UK confirms an election is available to treat the shares as sold and reacquired immediately before the issue, crystallising a gain on which relief can be claimed, with a further election to defer paying the tax until the shares are actually sold.

The officer or employee requirement

The seller must be an officer or employee of the company, or of a group company, throughout the two year period. “Office” and “employment” take their meanings from the Income Tax (Earnings and Pensions) Act 2003, so a validly appointed director is an officer whether or not they are paid.

There is no minimum number of hours and no minimum salary. What there is, is a requirement for the appointment to be real and properly documented. Resignations filed at Companies House shortly before completion, directors who were never formally appointed, and company secretaries whose appointment was never minuted are all familiar problems. So is the seller who steps down as a director eighteen months before a sale to “tidy things up” and unknowingly breaks the two year clock.

Non-executive and consultancy arrangements need care too. A consultant invoicing through their own company is not an officer or employee of the target. If the intention is to preserve a claim, the appointment needs to be on the register, minuted, and consistent with how the person actually engages with the business.

Trading company and trading group status

Section 165A defines a trading company as one carrying on trading activities “whose activities do not include to a substantial extent activities other than trading activities”. A trading group is assessed on its members’ activities taken together, with intra-group activities disregarded.

HMRC does not apply a single mechanical test. Its Capital Gains Manual at CG64090 lists the indicators it weighs: income from non-trading activities, the asset base of the company, expenses incurred and time spent by officers and employees on non-trading activities, and the company’s history. It then says that where neither the level of non-trading income nor the asset base suggests the non-trading element exceeds 20 per cent, the case is unlikely to warrant more detailed review. That 20 per cent is a review threshold used by HMRC, not a statutory safe harbour, and it is regularly reported as though it were the latter.

The Upper Tribunal decision in Allam [2021] UKUT 0291 (TCC), upholding the First-tier Tribunal at [2020] TC07532, is the case to know. A company with a substantial investment portfolio was held to have substantial non-trading activities, and the individual indicators were weighed rather than applied as separate percentage tests.

For sellers of owner-managed businesses, the practical risks are familiar: a large cash balance built up over years and never earmarked for the trade, an investment property held inside the trading company, or a dormant subsidiary parked in the group. HMRC’s guidance at CG64060 accepts that short-term lodgement of surplus funds can count as a trading activity where the funds are genuinely earmarked for the trade, but notes that long-term retention of significant trading earnings may amount to an investment activity in its own right. Where a balance sheet has drifted in that direction, the fix is usually structural and takes time, which is why the question belongs at the start of a sale process rather than at exchange.

How deal structure affects whether the conditions are met

Share sale or asset sale

This is the first structural fork and it decides whether the relief is in play at all. On a share sale, the shareholders dispose of their shares, the gain is theirs, and BADR can apply to it. On an asset sale by a limited company, the company disposes of the assets and pays corporation tax on any chargeable gain. The shareholder has made no disposal, so there is nothing for BADR to attach to. Getting the cash out afterwards, whether by dividend or by a solvent liquidation, is a separate step with its own tax treatment and its own conditions.

That asymmetry is one reason buyers and sellers so often start from opposite positions on structure, since buyers frequently prefer to buy assets and leave historic liabilities behind. We have set the arguments out in full in our guide to share sales and asset sales, and we act for both buyers and sellers on business sales and acquisitions, so we see the trade negotiated from both ends.

Alphabet shares and growth shares

Alphabet share structures, where each shareholder or family member holds their own lettered class so dividends can be declared separately, are common in owner-managed companies and are a frequent cause of failed claims. The problem is rarely the percentage of share capital. It is that the class often carries no voting rights, or carries no right to participate in surplus assets on a winding up, or has a dividend right that is entirely at the directors’ discretion. Any of those can take the holder outside the personal company definition even though they hold well over 5 per cent of the issued shares.

Growth shares and similar hurdle-based classes raise the same question in a sharper form. The whole point of a growth share is that it participates only in value above a hurdle, which means its share of distributable profits and of assets on a winding up may be nil on the day you test it. The proceeds alternative in section 169S(3)(c)(ii) exists partly to help here, but it is applied on the statutory assumptions described above, and the answer depends entirely on the drafting. These classes need to be reviewed against the tests when they are created, not when the buyer’s due diligence questionnaire arrives.

Share reorganisations and share-for-share exchanges before a sale

A pre-sale reorganisation, a new holding company inserted above the trading company, or a share-for-share exchange where part of the price is paid in the buyer’s shares all engage section 127, which treats the new holding as the same asset as the original shares. The consequence is that there is no disposal at that point, so there is nothing to claim relief on.

Section 169Q allows an election to disapply section 127 so that the reorganisation is treated as a disposal and a BADR claim can be made against it. The election must be made on or before the first anniversary of the 31 January following the tax year in which the reorganisation takes place. Whether to make it is a tax decision, and it is frequently a finely balanced one, because it means paying tax now on a gain that has not been received in cash. The legal job is to make sure the reorganisation is documented in a way that leaves the election available and the facts clearly evidenced. That conversation has to happen before the reorganisation is executed.

There is a related point worth knowing for recently incorporated businesses. Where shares were issued in exchange for the transfer of a business as a going concern, section 169I(7ZA) treats the personal company and officer or employee conditions as met for the period before the transfer during which the individual owned the business. A sole trader who incorporated eighteen months ago is not automatically starting a fresh two year clock.

Selling to an employee ownership trust

This is the point on which published guidance is most likely to be out of date, so it deserves stating plainly. Section 35 of the Finance Act 2026 restricted the capital gains tax relief on qualifying disposals to an employee ownership trust. For disposals made on or after 26 November 2025, where a gain accrues, only 50 per cent of that gain is a chargeable gain, and the legislation states expressly that the disposal is not to be regarded as a qualifying business disposal for BADR purposes. The previous position, under which a qualifying EOT disposal was treated as giving rise to neither a gain nor a loss, now applies only where no gain accrues in the first place.

That changes the arithmetic of the EOT route materially, and it sits alongside the conditions added by the Finance Act 2025, which require the trustees to be UK resident at the time of the disposal, impose a trustee independence requirement, and require the trustees to have taken all reasonable steps to ensure the consideration does not exceed market value. Any seller weighing an EOT against a trade sale needs current advice on both, not a comparison written before November 2025. We cover the structure and the legal process in our guide to selling to an employee ownership trust, and the alternative route of a sale to the existing management team on our management buy-outs and buy-ins page.

The legal housekeeping that most often breaks a claim

In our experience these are the recurring failures, and almost all of them were fixable two years earlier and unfixable by the time the buyer’s solicitors asked about them:

• A share class with no voting rights. The holder may own 40 per cent of the issued shares and still fail the personal company test, because the votes have to come from the holding itself.
• Articles that exclude a class from surplus assets on a winding up. Easily missed, because the class is still called “ordinary” and still receives dividends.
• Shares issued or transferred inside the two year window. A gift to a spouse, a transfer into trust, or a top-up allotment to get someone over 5 per cent all start a fresh clock on the new shares.
• A statutory register that does not match reality. Where the register of members, the certificates and the Companies House filings disagree, the two year period becomes a matter of evidence rather than a matter of record.
• A director who resigned, or was never properly appointed. Officer or employee status has to be continuous across the full two years, and it has to be documented.
• An investment-heavy balance sheet. Long-retained surplus cash with no identified trading purpose, a let property, or an investment portfolio can all put trading company status in issue.
• A dormant or non-trading subsidiary in the group. Trading group status is assessed across the members taken together.
• A rollover of equity into the buyer’s group. This can both defeat the “withdrawal” condition for an associated disposal and engage section 127 on the reinvested element.
• Rent charged on personally held trading premises. A full market rent can reduce associated disposal relief to nothing.

This is exactly the ground a proper vendor due diligence exercise is meant to cover before a buyer is in the room. Fixing a share class, regularising a register or restructuring a balance sheet is ordinary corporate work when there is time, and close to impossible once a two year clock has already run.

The two year clock, and when to start

Every route into the relief turns on a two year period ending with the disposal, or with cessation. That means the legal position has to be right 24 months before exchange, not at completion. A seller who begins thinking about structure when a buyer appears has, in practical terms, already fixed their eligibility.

We usually suggest the constitutional review happens at the point an exit becomes a plan rather than an idea: articles and share classes read against the tests, registers reconciled, appointments confirmed, the balance sheet looked at for non-trading drift, and anything that needs changing changed while there is still a clear two years ahead. Our business evolution work is largely this, and it tends to improve the deal itself as much as the tax position, because the same defects that threaten a relief claim also slow down due diligence and give a buyer something to price against. The wider sale process is set out in our legal guide to selling a business.

Claiming the relief

Relief must be claimed. It is not applied automatically. A claim is made through the self assessment tax return or by completing Section A of HMRC’s helpsheet HS275. The deadline is the first 31 January falling more than twelve months after the end of the tax year of disposal, so GOV.UK gives 31 January 2028 for a disposal in the 2025 to 2026 tax year, and on the same basis a disposal in the 2026 to 2027 tax year has a deadline of 31 January 2029. There is no limit on the number of separate claims, only on the cumulative £1 million of gains.

The claim itself is your accountant’s or tax adviser’s work, and it should be theirs. What it depends on is a documentary record that the conditions were met for the whole qualifying period, and that record is built out of the company’s constitutional documents, its statutory books and the transaction documents. Those are ours.

What this means for you

BADR is a tax relief with legal qualifying conditions. The rate and the lifetime limit are set by Parliament and will change again; the 5 per cent tests, the officer or employee requirement and trading status are satisfied or not satisfied by documents that a solicitor drafts and maintains. Sellers lose claims because of a share class, a register or a resignation date far more often than because of anything in the tax computation.

To say it once more, because it matters: this article is the legal framework, not tax advice. Your own position, the figures, the interaction with any other relief and the decision on whether to claim all need to be confirmed with your accountant or tax adviser, and the rates set out here can be changed at any Budget.

If you are planning an exit in the next two or three years and want the legal position checked while there is still time to put it right, we would be glad to look at it with you and to work alongside your accountant.
