Why the small print matters more than the headlines for Britain’s SMEs
There has been plenty of commentary following the Chancellor’s Autumn Budget 2026, including some rather entertaining discussions about the price of everyday essentials. But while the nation debates the cost of its groceries, there are some far more significant changes tucked away in the detail for business owners.
And, dare we say it, the Autumn Budget’s approach to entrepreneurship has something of a “let them eat cake” flavour. On the one hand, the Chancellor has announced an apparently generous new tax relief for business founders. On the other, an existing relief relied upon by business owners planning their eventual retirement or exit has been substantially reduced.
The real question is: how many ordinary business owners will actually benefit from the new generosity?
Founders’ Relief: An attractive headline, but who actually qualifies?
From 6 April 2027, the Government proposes to introduce a new Capital Gains Tax (CGT) Founders’ Relief, allowing qualifying founders to pay just 10% CGT on up to £10 million of lifetime gains when selling their businesses. On the face of it, that’s an extremely attractive incentive to encourage entrepreneurship and business growth.
However, the proposed qualifying criteria are exceptionally demanding. To qualify, an individual would need to have held at least 25% of the company’s ordinary share capital when the business commenced trading, retained their shares for at least five years and satisfied UK residency requirements.
The business would also need to meet substantial conditions, including:
- Annual turnover of at least £10 million.
- At least 15 qualifying full-time equivalent employees.
- A substantial UK presence and eligible trading activity.
- At least two of three demanding growth or innovation tests, potentially involving annual growth rates of 25%.
Certain sectors, including property development, dealing in land and financial services, would also be excluded. These conditions remain subject to consultation, but they demonstrate the Government’s intended direction.
This is not a relief designed for the typical owner-managed business. It is primarily targeted at high-growth businesses operating at considerable scale.
Perhaps the most revealing figure comes from HMRC itself: According to the HM Treasury Technical Consultation, the Government estimates that only around 600 individuals per year, across approximately 400 businesses, will benefit from the new relief. That rather puts the headline announcement into perspective.
The real sting: Business Asset Disposal Relief is being halved
While attention has focused on the new Founders’ Relief, arguably the more significant announcement for established SME owners is the reduction in Business Asset Disposal Relief (BADR).
BADR, previously known as Entrepreneurs’ Relief, allows qualifying business owners to pay a reduced rate of Capital Gains Tax when selling their businesses.
The BADR tax rate increased to 18% from April 2026. Now, from 6 April 2027, the lifetime limit on gains qualifying for BADR will fall from £1 million to just £500,000.
This represents a substantial reduction in the tax advantages available to business owners who have spent years building value in their companies.
What does this mean in pounds and pence?
Consider a business owner selling their company and realising a taxable capital gain of £1 million.
Assuming they qualify for BADR, have their full lifetime allowance available and would otherwise pay CGT at 24%, the difference is clear:
| Detail | Before 6 April 2027 | From 6 April 2027 |
| Gain qualifying for BADR | £1,000,000 | £500,000 |
| Tax at 18% | £180,000 | £90,000 |
| Remaining gain taxed at 24% | £0 | £120,000 |
| Total CGT | £180,000 | £210,000 |
That’s an additional £30,000 in Capital Gains Tax on exactly the same business sale.
For an owner planning to sell their business to fund retirement, that is hardly insignificant.
It is also worth remembering that BADR is a lifetime allowance, rather than an allowance that renews with each business sale. Previous qualifying disposals can therefore affect the relief available.
Two very different definitions of entrepreneurial success
There is something of a contradiction in the Government’s approach.
The new Founders’ Relief recognises that building a business involves considerable risk and that entrepreneurs should be rewarded when they eventually realise the value they have created.
But why should that principle apply predominantly to founders of high-growth companies?
The individual who builds a technology company to £20 million turnover has undoubtedly taken risks, created jobs and contributed to the economy.
But so has the person who starts a small business, employs a team of eight people, supports local suppliers, pays taxes and builds a profitable, sustainable company over 25 years.
Both have demonstrated entrepreneurship. Yet under the proposed rules, their treatment on exit could be very different.
There is a reasonable economic argument for encouraging high-growth businesses, but it is equally important not to overlook the contribution of the established SMEs that form the backbone of the UK economy.
What should business owners be thinking about now?
For anyone considering selling their business within the next few years, these changes make advance planning more important than ever.
In particular, business owners should be reviewing:
- Their exit timeframe: Could the reduction in BADR affect a sale being considered over the next 12-24 months?
- Their eligibility for BADR: Are the relevant ownership, employment and trading conditions being met?
- Their shareholding arrangements: Could the ownership structure affect the reliefs available?
- Their business valuation: What is the realistic value of the business, and what would the after-tax proceeds look like?
- Their retirement plans: Will the net proceeds of a sale deliver the financial security they are working towards?
Accelerating a business sale purely to secure a tax advantage is not necessarily the right commercial decision. However, where an exit is already being considered, understanding the implications of the April 2027 deadline is essential.
Special rules may also apply to transactions spanning the changeover date, making professional advice particularly important.
Beyond the headlines: Other changes worth watching
The 2026 Autumn Budget also contains measures that will affect business owners in other ways.
There is welcome support for certain retail, hospitality and leisure businesses through changes to business rates, while the new EMI2 employee share arrangements may offer opportunities for growing businesses to attract and retain talent.
For owners who also hold investment properties personally, increases in the taxation of property income will need to be factored into their financial planning.
And while the decision to retain the £20,000 annual cash ISA allowance is welcome, the wider changes to savings and investment income taxation remain relevant when considering how business owners extract and invest their wealth.
These measures reinforce why the impact of a Budget cannot be assessed simply by looking at Corporation Tax rates or the announcements receiving the most media attention.
Our perspective at Palmers Accounting
At Palmers, we work with business owners at every stage of their journey, from establishing their first company to growing an established business and ultimately preparing for an exit.
For many owners, their company represents not just their livelihood but their largest financial asset and an important part of their retirement planning.
While the new Founders’ Relief is welcome for the relatively small group of entrepreneurs who will qualify, the reduction in BADR is likely to be a much more relevant consideration for the majority of established SME owners contemplating an exit.
Our concern is that the attractive headline surrounding Founders’ Relief risks obscuring a less favourable change for the wider business community.
The message for business owners is straightforward: don’t wait until a sale is imminent to start thinking about your exit.
Understanding what your business is worth, how it can be made more attractive to potential buyers, and how much of the eventual proceeds you will actually retain should form part of your ongoing financial planning.
Because building a successful business is only part of the journey. Making sure you realise its full value when the time comes matters just as much.
This article reflects announcements made in the Autumn Budget 2026 on 28 October 2026. Some measures, including the detailed qualifying conditions for Founders’ Relief, remain subject to consultation and legislation. Individual tax circumstances vary and professional advice should be obtained before making decisions.
