The latest UK Budget introduces new opportunities for qualifying founders while narrowing existing tax reliefs for business disposals. For owners considering a sale, the implications extend beyond tax rates to transaction timing, deal structure and long-term exit planning.
The UK Budget, announced on 28 October 2026, delivers a mixed outlook for business owners and the M&A market.
The introduction of a proposed Founders' Relief, offering a 10% Capital Gains Tax (CGT) rate on up to £10 million of qualifying lifetime gains, represents a potentially significant incentive for entrepreneurs building high-growth businesses.
At the same time, the government has announced a reduction in the lifetime limit for Business Asset Disposal Relief (BADR), from £1 million to £500,000, effective from 6 April 2027.
Together, these measures create a notable distinction between the treatment of qualifying high-growth founders and many owners of established businesses.
For those considering an exit over the next 12 to 24 months, the question is no longer simply what their business might be worth. It is also how the timing, structure and circumstances of a transaction could influence the proceeds they ultimately receive.
Founders' Relief: A significant opportunity, but not for everyone
The proposed Founders' Relief is among the Budget's most consequential announcements for entrepreneurs.
From 6 April 2027, eligible individuals disposing of shares in qualifying high-growth and innovative businesses could benefit from a 10% CGT rate on up to £10 million of lifetime gains.
Compared with the standard higher CGT rate of 24%, the potential tax difference is substantial. On £10 million of fully qualifying gains, the difference could reach £1.4 million.
However, eligibility is deliberately restrictive.
Under the proposals currently being consulted on, qualifying conditions include founder ownership and holding periods, UK residence requirements, minimum business scale, and evidence of sustained growth or qualifying innovation.
Certain business activities, including financial services, are proposed to be excluded. This means the relief is unlikely to apply equally across the professional and financial services sectors.
For founders who meet the eventual requirements, the measure could influence decisions about when to sell, whether to pursue further growth and how to approach succession or investment.
For others, the headline 10% rate may have little practical relevance.
The government consultation remains open until 30 November 2026, with final legislation still to follow. Business owners should therefore avoid making transaction decisions based on assumed eligibility.
Business Asset Disposal Relief: A narrower benefit for established owners
While Founders' Relief introduces a potentially valuable new incentive, the reduction in BADR represents a less favourable development for many business sellers.
BADR currently allows eligible individuals to pay CGT at 18% on up to £1 million of qualifying lifetime gains.
From 6 April 2027, that lifetime limit will fall to £500,000.
Assuming the standard 24% CGT rate applies above the limit, the maximum tax benefit available through BADR will consequently fall from £60,000 to £30,000.
For a qualifying owner with at least £1 million of eligible gains and their full lifetime allowance available, the difference could mean an additional £30,000 in tax.
Although this may be modest relative to the value of a substantial transaction, it is not insignificant. The impact may be greater in aggregate where several shareholders are considering a sale, although each individual's eligibility and tax circumstances must be assessed separately.
Importantly, the reduction does not represent a general increase in CGT rates. It reduces the amount of gains eligible for a preferential rate.
The broader CGT position has therefore remained relatively stable, but the tax advantages available to certain business owners are becoming more limited.
Why transaction timing now deserves closer attention
For owners already considering a sale, the April 2027 changes introduce an additional consideration into transaction planning.
However, the relevant tax date is not necessarily the day funds are received or a transaction formally completes.
Under UK CGT rules, the date of disposal for an unconditional contract is generally the date the contract is entered into. Where the contract is conditional, the relevant date is generally when the conditions are satisfied.
In regulated sectors, this distinction can be particularly important.
For example, an acquisition involving an FCA-regulated business may require regulatory approval for a change in control. Depending on how the transaction documents are structured, that approval may affect when the contract becomes unconditional.
The government has also announced special provisions for certain contracts entered into before 6 April 2027 but completed afterwards. Their application requires careful consideration.
Key dates for business owners
28 October 2026: Budget announcement
New Founders' Relief and the reduction in the BADR lifetime limit announced.
30 November 2026: Founders' Relief consultation closes
The government will use consultation responses to finalise the proposed eligibility conditions.
Before 6 April 2027: Review existing exit plans
Owners considering a transaction should assess potential tax implications, buyer readiness, transaction structure and any regulatory requirements.
6 April 2027: New measures scheduled to take effect
Founders' Relief is intended to begin for qualifying disposals, while the BADR lifetime limit falls to £500,000.
The practical implication is not that business owners should rush to complete a transaction before April.
A sale involves commercial negotiations, financial and legal due diligence, buyer financing and, in some sectors, regulatory approvals. Accelerating a transaction purely to secure a potential tax advantage could introduce risks that outweigh the benefit.
Instead, the Budget reinforces the importance of considering tax and transaction planning together, sufficiently early in the process.
How could the Budget affect M&A across professional and financial services?
The implications will differ across sectors, particularly because the proposed Founders' Relief does not apply universally.
Wealth management and insurance
For wealth management and insurance business owners, the reduction in BADR may be the more immediately relevant development.
Financial services activities are among those proposed to be excluded from Founders' Relief, although eligibility will depend on the final rules and the specific activities undertaken by a business.
For owners contemplating retirement, succession or consolidation, the timing and structure of a sale may therefore warrant renewed attention.
In regulated businesses, the need for appropriate approvals and the importance of client continuity can add further complexity to transaction planning.
Accountancy and legal services
Accountancy and legal practices face a similar need to consider ownership transitions well in advance.
Partner succession, client relationships, management continuity and the structure of the business can all influence how a transaction is approached.
The proposed Founders' Relief should not be assumed to apply to professional practices, particularly where excluded activities or other eligibility restrictions are relevant.
For these businesses, the broader lesson is that succession planning cannot be reduced to securing a favourable tax outcome. Preserving business value and identifying a suitable successor or acquirer remain central considerations.
TICC and specialist services
For qualifying businesses in technology, information, communications, compliance and specialist technical services, the proposed Founders' Relief could create a more significant opportunity.
Certain high-growth businesses, potentially including some specialist technical or Fire & Safety companies, may fall within the intended scope of the relief.
However, sector classification alone will not establish eligibility.
Founders will need to consider the proposed ownership, business scale, growth, innovation and residence requirements before drawing conclusions.
For businesses that do qualify, the new relief could become an additional factor in long-term growth and exit decisions.
Across all sectors, the distinction is important: tax changes may influence a seller's willingness or timing, but they do not replace the underlying commercial rationale for a transaction.
Beyond tax: Employee ownership and management succession
The Budget also includes changes to tax-advantaged employee share arrangements.
The proposed EMI2 scheme will increase the value of tax-advantaged options employees can hold from £60,000 to £120,000 from April 2027, alongside additional flexibility within employee incentive arrangements.
These measures could support businesses seeking to retain senior management, reward key employees and align leadership incentives with long-term performance.
This may be particularly relevant to private equity-backed businesses and acquisition-led groups, where retaining experienced management teams can be important to delivering a growth strategy.
Although these changes are not directly related to the taxation of business sales, they form part of the wider environment in which companies prepare for investment, succession and expansion.
Will the Budget change buyer appetite?
Tax changes can influence the decisions of individual sellers, but the factors driving acquisition interest remain broader.
Buyers and investors continue to evaluate businesses according to earnings quality, growth potential, market positioning, management capabilities and strategic fit.
A business with sustainable revenue, strong client relationships and credible expansion opportunities may remain attractive regardless of changes to a seller's personal tax position.
The Budget could nevertheless influence the availability and timing of acquisition opportunities.
Some owners may revisit plans for a sale before April 2027, while qualifying founders may see an incentive to continue building their businesses before pursuing an exit.
These are potential behavioural effects rather than guaranteed market outcomes.
For acquirers, the result could be a changing pattern of seller engagement and transaction discussions over the coming months.
For sellers, it reinforces the value of understanding the market, identifying credible buyers and preparing for a transaction before external deadlines become a source of pressure.
Planning ahead: The opportunity behind the announcement
The most important implication of the Budget may not be the introduction or reduction of any single tax relief.
It is the renewed importance of planning.
Business owners considering a sale over the next 12 to 24 months should have a clear understanding of their objectives, the attractiveness of their business to potential acquirers and the practical requirements of a transaction.
Tax treatment is one element of that assessment. Valuation, deal structure, buyer suitability, regulatory approvals and post-completion expectations can be equally significant.
For some founders, the proposed new relief may create opportunities. For others, the reduction in BADR may prompt an earlier review of existing exit plans.
In either case, the strongest decisions will be those made with a complete understanding of the commercial and financial implications.
The Budget may change the economics of an exit, but it should not be the sole reason for one.
At Capital and Trust, we work with business owners, investors and acquirers across professional and financial services to identify opportunities and support strategic M&A transactions.
For owners considering their next chapter, understanding the available options early remains one of the most valuable starting points.
