Business Asset Disposal Relief 2026: What UK Business Owners Need to Know Before Selling

For many UK entrepreneurs, building a business is the work of a lifetime. But when the time comes to step back: whether for retirement, a new venture, or a simple lifestyle change: the taxman is often the final hurdle. Historically, Business Asset Disposal Relief (BADR) has been the "golden ticket" for business owners, allowing them to pay a significantly lower rate of Capital Gains Tax (CGT) on their hard-earned profits.
However, the landscape is shifting. Following the 2026 Spring Statement, the rules surrounding BADR have undergone their most significant update in years. If you are considering selling your business, or even just a portion of your shares, understanding these changes is no longer optional: it is essential for protecting your exit value.
In this guide, we’ll break down the 2026 changes, the new 18% rate, and how you can work with accountants for small business to ensure you aren't paying more tax than necessary.
The Big Change: From 14% to 18%
The headline news for 2026 is the rate increase. For years, BADR (formerly known as Entrepreneurs’ Relief) offered a flat 10% tax rate. That rose to 14% in April 2025, and as of 6 April 2026, the rate has officially climbed to 18%.
While 18% is still lower than the standard higher rates of Capital Gains Tax, it represents a nearly 30% increase in the tax bill compared to just two years ago. For a business owner realizing a £1 million gain, the tax due has jumped from £100,000 (at the old 10% rate) to £180,000 today.
The Staged Increases at a Glance:
Before 6 April 2025: 10% Tax Rate
6 April 2025 – 5 April 2026: 14% Tax Rate
From 6 April 2026 onwards: 18% Tax Rate
Despite the rate hike, the £1 million lifetime limit remains in place. This means you can still claim this preferential rate on up to £1 million of qualifying gains over your entire lifetime. Anything above that threshold will be taxed at the standard CGT rates, which often requires the expertise of corporation tax accountants to navigate effectively.

Who Still Qualifies for BADR in 2026?
While the rate has changed, the eligibility criteria have remained largely consistent. To claim the 18% rate on your disposal, you generally need to meet the following conditions for at least two years leading up to the sale:
For Share Sales: You must be an employee or office holder (like a director) of the company. You must also hold at least 5% of the ordinary share capital and 5% of the voting rights.
For Sole Traders and Partners: You must have owned the business for at least two years. If you are closing the business, the assets must be sold within three years of the business ceasing to trade.
Trading Requirement: The company must be a "trading company" or the holding company of a trading group. Companies that purely hold investments (like property portfolios) often do not qualify.
Navigating these "trading status" rules can be tricky. Many business owners find themselves disqualified because they left too much "excess cash" in the business or began focusing on passive investments. This is why mid-year tax planning is vital long before you actually put the "For Sale" sign up.

The £1 Million Lifetime Limit: A Finite Resource
It is important to remember that BADR is a "lifetime" relief. It isn't per business or per year; it’s a total cap on the gains you can ever claim at the reduced rate.
If you have previously sold a business and claimed Entrepreneurs’ Relief or BADR, those amounts count toward your £1 million limit. Once you hit that cap, the 18% rate is gone, and you will move into the standard CGT brackets (which are currently 18% for basic rate taxpayers and 24% for higher rate taxpayers on non-residential assets).
Because this limit is so valuable, many entrepreneurs are now looking at more complex structures, such as Family Investment Companies or Employee Ownership Trusts, to manage their tax exposure. These strategies require specialized accounting services to implement correctly.
Timing the Sale: The "Anti-Forestalling" Trap
With the jump from 14% to 18% in April 2026, many owners rushed to sign contracts in late March. However, HMRC is well aware of these tactics.
The "date of disposal" is usually the date of an unconditional contract. However, "anti-forestalling" rules are in place to prevent people from artificially bringing forward a sale just to save tax. If you signed a contract before April 2026 but the actual completion (and transfer of ownership) happens after, HMRC may still apply the 18% rate unless you can prove the timing was for genuine commercial reasons and not just tax avoidance.
If you are caught in this transition period, it is essential to have your paperwork reviewed by local accountants who understand the latest HMRC manuals.
Planning Your Exit: Three Steps to Take Now
Selling a business isn't something you do on a whim. To maximize your BADR and ensure a smooth transition, follow these three steps:
1. The Two-Year Health Check
Since most BADR rules require a two-year qualifying period, you need to "clean up" your business at least 24 months before a sale. Are you a director? Do you have your 5% shares? Is the company definitely classified as "trading"?
2. Manage Your Assets
If your business has a lot of "non-trading" assets (like a surplus of cash that isn't being used for business operations), HMRC might argue the company is no longer a trading entity. You may need to distribute that cash or reinvest it into the business to preserve your BADR eligibility.
3. Get Expert Matching
Every business is different. A tech startup has different tax needs than a local construction firm. Using a service like Accountant Search can help you match with an accountant who specializes in your specific sector. Whether you need London-based tax advisors or specialist corporation tax experts, getting the right fit is the first step toward a successful sale.
Conclusion: Is the 18% Rate Still a Good Deal?
While nobody likes a tax hike, 18% remains a competitive rate for business disposals, especially when compared to the 40% or 45% Income Tax rates many business owners pay on dividends or salary.
The 2026 changes highlight a clear trend: the window for ultra-low tax exits is narrowing. If you are a business owner, the "wait and see" approach could be costing you tens of thousands of pounds. By engaging with professional accountants for small business today, you can lock in your strategy, ensure you meet the qualifying criteria, and prepare for a rewarding exit.
