Understanding the Tax Implications of a Business Sale

When selling your business, understanding the tax implications is essential to maximising your net proceeds. A successful sale is about more than just achieving a strong valuation; it’s also about structuring the deal efficiently and taking advantage of the reliefs available. Early planning, combined with specialist advice, can make a significant difference to what you ultimately retain from the sale.

Why Tax Planning Matters Before You Sell

Tax considerations should never be an afterthought. The structure of your deal (whether you sell shares, assets, or transition to an Employee Ownership Trust (EOT)) directly affects how much tax you pay and when. By starting early, you give yourself time to align ownership, review shareholder positions, and make use of available reliefs before heads of terms are signed.

Common Tax Liabilities When Selling a Business

Identify who pays tax and on what

When you sell your business, you may face one or more of the following taxes, depending on the structure of the sale:

• Capital Gains Tax (CGT): Charged on the gain made from selling shares or business assets. For disposals on or after 30 October 2024 the main CGT rates are 18% (within the basic rate band) and 24% (above it). Before that date the rates for most business assets were 10% and 20%.
• Corporation Tax: If a company sells its assets and then distributes the proceeds to shareholders, Corporation Tax is paid first, followed by potential personal tax on distribution.
• Income Tax: May apply on certain payments made to owners or directors during or after completion (for example, earn-outs or employment-related payments).

Business Asset Disposal Relief (formerly Entrepreneurs’ Relief)

Business Asset Disposal Relief (BADR) allows qualifying individuals to pay a reduced CGT rate on the first £1 million of lifetime qualifying gains: 14% for disposals from 6 April 2025 and 18% from 6 April 2026 (it was 10% before 6 April 2025) when selling all or part of a business. To qualify, you generally need to:

• For a standard non-EMI share disposal, hold at least 5% of ordinary share capital and voting rights, and meet the applicable 5% economic entitlement test for profits and assets on winding-up or proceeds on a sale of the company.
• Have been an officer or employee of the company for at least two years prior to sale.
• Sell shares in a trading company or holding company of a trading group.

Check every applicable condition and the relevant qualifying period before relying on relief. Planning cannot guarantee eligibility; a specialist should review the facts and any changes before disposal.

Share Sale vs Asset Sale

Share Sale

In a share sale the company retains its assets and liabilities while ownership of the shares changes. An individual seller may qualify for CGT treatment and reliefs, but buyer and seller preferences differ. Warranties, indemnities and due diligence allocate risks; neither side should assume that a share sale is always preferable.

Asset Sale

In an asset sale, the buyer acquires selected assets (such as stock, equipment, goodwill, or customer contracts) but not the company itself. The selling company pays Corporation Tax on any gain from these disposals. When proceeds are later distributed to shareholders, additional personal tax may apply. This often results in a higher overall tax burden for the seller, although buyers may prefer it for flexibility.

Employee Ownership Trust (EOT) Sales

For qualifying companies, selling a controlling interest (more than 50%) to an Employee Ownership Trust can attract Capital Gains Tax relief. For disposals before 26 November 2025 the gain was fully relieved; for disposals on or after that date the Finance Act 2026 restricts the relief to 50% of the qualifying gain, with the remainder taxed under the normal rules. An EOT can support succession without an external trade buyer, but the price and payment schedule depend on supportable valuation and affordable funding. To qualify, the business must meet specific trading and ownership tests, and the trust must acquire the required controlling interest, including the relevant voting, profit and capital rights. EOT structures also require ongoing compliance and professional governance once established.

Timing and Structuring Considerations

• Ownership review: Ensure shares are held personally (not through another entity) and qualify for reliefs.
• Sale timing: Deferred payment does not automatically defer the tax point or spread a gain over tax years. Review the disposal date and the treatment of fixed, contingent and unascertainable consideration before agreeing terms.
• Pre-sale dividends: Model the dividend tax cost, available reserves and effect on purchase price. Extracting profits before completion is not automatically tax-efficient.
• Earn-outs: Understand how deferred payments and performance-linked earn-outs are taxed; timing and documentation are critical.
• Pension and estate planning: Integrate sale proceeds into your wider financial plan to minimise longer-term tax exposure.

Working with Professional Advisers

Coordinate specialist tax advice

Tax efficiency depends on coordination between your accountant, corporate finance adviser, and legal team. The right structure depends on your personal circumstances, the buyer’s requirements, and the form of consideration (cash, shares, loan notes, or EOT funding). Engaging specialists early avoids rushed or suboptimal decisions at completion.

Compare after-tax proceeds, payment risk and ongoing obligations across the proposed structures. If considering employee ownership, check EOT eligibility; for retirement objectives, review sale readiness and retirement timing. This page remains subject to professional factual review.
