Exit planning used to feel like something founders dealt with later, once the business was actually on the market. The revised Business Asset Disposal Relief rules have changed that calculation entirely. If you built your company with the expectation of a reduced Capital Gains Tax rate on exit, the recent Budget changes mean you need to revisit those assumptions sooner rather than later. Business asset disposal relief UK 2026 is a materially different proposition from what it was even two years ago, and I’ve spoken to several founders who were genuinely surprised by the revised numbers when they modelled their exits properly for the first time.
This guide cuts through the noise. What the relief actually covers, what qualifying conditions apply, how the lifetime allowance has shifted, and what practical steps you should be taking well before any sale discussions begin.
What business asset disposal relief actually does
Business Asset Disposal Relief (BADR), previously called Entrepreneurs’ Relief, reduces the rate of Capital Gains Tax payable when you dispose of qualifying business assets. Rather than paying the standard CGT rate on gains, eligible individuals pay a preferential rate. The relief applies to gains made by individuals, not companies, which matters for how you structure your business ahead of a sale.
Following the October 2024 Budget, the preferential rate changed. HMRC confirmed that for disposals made on or after 6 April 2025, the BADR rate increased to 14%, and from 6 April 2026 it rises again to 18%. That second step is now in effect. To put it plainly: the gap between BADR and the standard higher CGT rate has narrowed considerably, but the relief still delivers a meaningful saving on large gains. On a £1m gain, the difference between 18% and 24% is £60,000. On a £5m gain, that figure becomes impossible to ignore.
For detailed background on the current CGT rates and how the relief integrates with wider Capital Gains Tax rules, the HMRC guidance on business asset disposal is the most reliable reference point.
The qualifying conditions founders must meet
The relief is not automatic. HMRC applies a specific set of conditions, and falling short of any single one disqualifies the entire gain from the preferential rate. I’d argue these conditions are where most founders encounter problems, usually because they weren’t structured correctly at the point of incorporation.
For a trading company disposal, the key conditions are:
- You must have owned the shares for at least two years immediately before the disposal.
- The company must be a trading company (or holding company of a trading group) throughout that two-year period. Investment activity, including significant property holdings, can jeopardise this classification.
- You must be an employee or officer of the company throughout the two-year qualifying period.
- Your shares must entitle you to at least 5% of the ordinary share capital and at least 5% of the voting rights. You must also be entitled to at least 5% of the distributable profits and net assets on a winding-up, or alternatively 5% of the sale proceeds in the event of a disposal of the whole company.
The 5% threshold is a genuine trap for founders who have diluted heavily through multiple funding rounds. If your equity has dropped below 5% through investor dilution, you may have lost BADR eligibility. There is a mechanism called an election under the 2019 Finance Act rules to crystallise a deemed gain at the point of dilution below 5% and bank the relief at that point, but this requires forward planning. By the time you’re heading to exit, it’s often too late to use it.
How the lifetime allowance has changed
The lifetime allowance for BADR remains at £1 million of qualifying gains. This has not changed since the reduction from £10 million in 2020. What has changed is the rate at which that allowance delivers value, given the stepped rate increases now in place.
The practical consequence: founders who have already used BADR on a previous exit get no further relief once the £1m lifetime limit is exhausted. It’s a cumulative allowance, not a per-disposal one. If you sold a previous business and claimed BADR on £800,000 of gains, you have £200,000 of lifetime allowance remaining. This is something many serial founders overlook entirely, particularly those who sold earlier businesses informally or via a share buyback without a formal CGT computation at the time.
It’s also worth noting that Investors’ Relief, the separate relief aimed at external investors in unlisted trading companies, still carries a higher lifetime limit (currently £10 million), though its conditions are quite different and it’s not available to employees or officers of the company. That distinction matters for how you think about co-founder and investor structures.
What structures put the relief at risk
Several common business decisions can unintentionally disqualify BADR, and founders often make them without understanding the CGT implications. Property held inside the trading company is the most frequent issue I see raised. If a significant proportion of the company’s assets or income is non-trading, HMRC may not accept trading company status for the whole two-year qualifying period. This is especially relevant for businesses that have accumulated cash or invested in property as a store of value.
Holding company structures require particular care. If you own shares in a holding company that sits above a trading subsidiary, BADR can still apply, but the group must qualify as a trading group and the conditions around employment and shareholding must be met at the holding company level. Getting this wrong at the point of setting up a holding company structure is costly. I’ve written previously about how to structure a holding company in the UK, and the BADR implications are one reason the structuring decisions you make early on carry long-term consequences.
Share classes also matter. If your company has created alphabet shares or restructured equity in ways that affect voting rights, profit entitlements, or winding-up rights, the 5% tests may not be satisfied even if you nominally hold more than 5% of the share capital.
Planning steps to take well before a sale
The two-year qualifying period means any structural fixes need to happen at least 24 months before completion of a sale. This is not advisory padding; it’s a hard HMRC condition. A tax adviser can help you review the position, but there are a few specific questions worth working through now.
First, check your trading status. If your accountant’s year-end filing classifies significant revenue as investment income, or if your balance sheet carries substantial property or cash assets, consider whether this affects trading company status. Taking specialist advice on this point is not excessive caution; it’s straightforward commercial prudence.
Second, review your equity position. If you’re approaching or below the 5% threshold, talk to your solicitor about the deemed gain election mechanism. Doing this retroactively is not possible.
Third, model the actual after-tax proceeds. Founders sometimes focus on headline valuation without modelling net proceeds properly. At an 18% BADR rate versus a 24% standard CGT rate, the difference is meaningful but not transformative on smaller exits. On larger exits, it absolutely is. Running the numbers properly informs negotiating posture as well as planning decisions. This is precisely where fractional finance directors can add significant value, particularly for founders who don’t have an FD embedded in the business full-time.
Fourth, consider how intellectual property is held inside the business. If valuable IP sits outside the company structure, it may not form part of the qualifying disposal. The decisions around how and where to hold intellectual property in a UK business intersect directly with exit tax planning.
The honest position on BADR in 2026
Business asset disposal relief UK 2026 is still worth claiming. An 18% rate versus 24% on large gains is a real saving. But it is no longer the transformative relief it once was, and the conditions are unforgiving. The founders who benefit most are those who structured correctly from the beginning, monitored their qualifying conditions actively, and planned their exit with specific tax dates in mind rather than treating BADR as an afterthought.
If you’re two or more years from a planned exit, you still have time to fix most structural issues. If you’re closer than that, your options narrow quickly. Either way, this is not a conversation to have for the first time when a buyer’s offer letter arrives.
Frequently Asked Questions
What is the Business Asset Disposal Relief rate in 2026?
From 6 April 2026, the BADR rate is 18% on qualifying gains. This follows the interim rate of 14% that applied between 6 April 2025 and 5 April 2026. The standard higher Capital Gains Tax rate for shares is currently 24%, so the relief still delivers a meaningful saving on larger exits.
What is the lifetime allowance for Business Asset Disposal Relief?
The lifetime allowance remains at £1 million of qualifying gains per individual. This limit is cumulative across all disposals throughout your lifetime, not per transaction. If you’ve used BADR on a previous exit, the amount already claimed reduces what you can claim in future.
Do I still qualify for BADR if investor dilution has taken my shareholding below 5%?
If your shareholding has fallen below 5% due to dilution, you may have lost BADR eligibility on any gain accrued after that point. However, there is an election mechanism introduced in the 2019 Finance Act that allows you to treat a deemed disposal at the point of dilution and crystallise the relief at that moment. This must be done proactively and cannot be applied retrospectively.
How long must I own shares to qualify for BADR?
You must have owned the shares for at least two continuous years immediately before the disposal. During that period you must also be an employee or officer of the company, and the company must qualify as a trading company throughout. If either condition is broken at any point in the two years, BADR will not apply.
Can I claim BADR if my company has a holding company structure?
Yes, BADR can apply where you hold shares in a holding company above a trading subsidiary, but only if the group qualifies as a trading group and you meet the 5% shareholding, voting, and employment conditions at the holding company level. The structure must be set up correctly and maintained throughout the qualifying period.
