Business exit strategies: tax planning and exit considerations for 2026/27

Choosing the right business exit strategies is about much more than finding a buyer. Whether you intend to retire, pass the company to family members, sell to management or attract an external investor, the decisions you make before negotiations begin can have a significant impact on the amount you ultimately keep after tax.

Many business owners focus almost entirely on the headline sale price. However, the structure of the transaction, the timing of the disposal and the availability of tax reliefs can make a substantial difference to the final proceeds. Any gain arising is charged under the wider Income Tax and CGT framework explained in our ultimate guide to personal tax in the UK. Effective business exit planning allows potential tax issues to be identified early, reducing the likelihood of unexpected liabilities after months of commercial negotiations.

This guide explains the main business exit options available to owner-managed businesses, how business exit tax is calculated, the importance of Business Asset Disposal Relief, and why planning well before marketing your business can significantly improve the overall outcome.

Why business exit planning should begin early

Preparing to leave your business is rarely something that should be left until the last minute. Most successful exits are the result of careful planning over many months, and in some cases several years.

Starting your business exit planning early gives you time to review:

• Your personal financial objectives.
• The most suitable exit route.
• Your company’s trading status.
• Shareholding structures.
• Eligibility for Business Asset Disposal Relief.
• Potential tax exposures before negotiations begin.

Early planning also provides greater flexibility. Once Heads of Terms have been agreed, opportunities to restructure the transaction for tax efficiency are often much more limited.

Common business exit strategies

Every business owner has different commercial and personal objectives, so there is no single exit strategy that suits every business.

Common options include:

Selling to a third party

This is often the most common approach where an independent buyer acquires the business.

A competitive sale process may maximise value, although buyers will usually undertake detailed financial, legal and tax due diligence before completing the transaction.

Management buyout

A management buyout allows existing senior employees to purchase the company.

Because the management team already understands the business, the transition may be smoother than a sale to an external purchaser.

Family succession

Passing ownership to family members can preserve the long-term future of the business while allowing the current owner to step back gradually.

Succession planning should also consider inheritance tax, ownership structures and future management responsibilities.

Partial sale

Some owners choose to sell only part of the business while remaining involved.

This approach can release capital while allowing the founder to continue supporting future growth.

Business exit tax explained

Understanding business exit tax is essential before deciding how the transaction should be structured.

The tax treatment depends largely on what is being sold.

In most cases, either:

• The shareholders sell their shares.
• The company sells its business assets.

Although both transactions may achieve the same commercial objective, they often produce very different tax outcomes.

Where shareholders sell shares, the gain generally falls within the Capital Gains Tax regime.

Where the company sells business assets, the company usually pays Corporation Tax before shareholders consider how to extract the proceeds. This can result in two layers of taxation depending on how the money is distributed.

Understanding these differences before negotiations begin is one of the most valuable parts of exit planning.

Share sale versus asset sale

The structure of the transaction often influences both the buyer’s commercial objectives and the seller’s tax position.

Share sale

Under a share sale, the purchaser acquires ownership of the company by buying the shareholders’ shares.

Advantages often include:

• Capital Gains Tax treatment for shareholders.
• Potential eligibility for Business Asset Disposal Relief.
• Sale proceeds normally received directly by shareholders.
• A simpler extraction of value after completion.

However, buyers also acquire the company’s existing liabilities, making due diligence particularly important.

Asset sale

Under an asset sale, the company sells selected assets rather than the shareholders selling their shares.

Assets commonly sold include:

• Goodwill.
• Commercial property.
• Plant and machinery.
• Stock.
• Customer contracts.
• Intellectual property.

The company normally receives the proceeds and may pay Corporation Tax on taxable gains or profits before shareholders extract funds personally.

Although buyers sometimes prefer asset purchases, sellers should fully understand the potential tax implications before agreeing the structure.

Business Asset Disposal Relief explained

Business Asset Disposal Relief (BADR) can significantly reduce the Capital Gains Tax payable when qualifying business owners dispose of their business.

The relief applies to qualifying lifetime gains up to the current £1 million lifetime limit.

For qualifying disposals made on or after 6 April 2026, the reduced Capital Gains Tax rate under Business Asset Disposal Relief is 18%.

BADR may apply to:

• The sale of shares in a qualifying trading company.
• The disposal of a sole trader business.
• The disposal of a partnership interest.
• Certain qualifying business assets disposed of after a business has ceased.

However, the relief is not automatic. Business owners must satisfy all of the qualifying conditions immediately before disposal. Successfully navigating Business Asset Disposal Relief as a UK entrepreneur means reviewing these conditions well before any sale process begins.

Qualifying conditions for Business Asset Disposal Relief

Although the detailed rules depend on the type of disposal, shareholders will generally need to satisfy conditions relating to:

• Employment or office-holder status.
• Minimum shareholding requirements.
• Voting rights.
• The company being a trading company.
• The qualifying ownership period before disposal.

Even relatively small changes to ownership or company activities before completion can affect entitlement to the relief, making early tax planning particularly valuable. A detailed review of what’s involved in qualifying for Business Asset Disposal Relief can help identify any risk areas well before a sale is agreed.

Business Asset Disposal Relief rates in 2026/27

For qualifying disposals made on or after 6 April 2026, Business Asset Disposal Relief applies a reduced Capital Gains Tax rate of 18% on qualifying lifetime gains up to the £1 million lifetime limit. This is higher than an earlier period when qualifying business asset disposals were taxed at 10%, so the completion date has a direct bearing on the rate that applies.

The lifetime limit applies across all qualifying claims rather than to each individual business sale. If you have previously claimed Business Asset Disposal Relief, any remaining lifetime allowance should be reviewed before the transaction proceeds.

Where the qualifying conditions are not met, or gains exceed the lifetime limit, the excess is generally taxed using the standard Capital Gains Tax rules. Reviewing Business Asset Disposal Relief at the present rates before agreeing Heads of Terms avoids relying on figures that may already be out of date.

Timing your business exit

The timing of a disposal can have a significant influence on both the commercial value of the business and the overall tax position.

Before agreeing a sale, business owners should consider:

• Whether the qualifying period for Business Asset Disposal Relief has been completed.
• Expected changes to tax legislation.
• The company’s recent trading performance.
• Current market conditions.
• Personal retirement or succession objectives.
• The impact of deferred consideration arrangements.

Delaying or accelerating a disposal by only a short period can sometimes affect eligibility for valuable tax reliefs.

Preparing your business for sale

Well-prepared businesses generally experience smoother due diligence, fewer unexpected issues and greater buyer confidence.

Before marketing your company, consider reviewing:

• Statutory accounts and management accounts.
• Corporation Tax, VAT and PAYE compliance.
• Companies House records.
• Shareholder agreements.
• Commercial contracts.
• Property ownership.
• Employment agreements.
• Intellectual property rights.

Resolving outstanding issues before negotiations begin often reduces the likelihood of price adjustments or delays during the sale process. If you’re only at the stage of thinking of selling your business, starting this preparation early gives buyers far greater confidence once formal discussions begin.

Deferred consideration and earn-outs

Many business sales involve payments being made over time rather than entirely on completion.

Deferred consideration may include:

• Fixed instalment payments.
• Performance-based earn-outs.
• Profit-related payments.
• Completion account adjustments.

Although these arrangements can help bridge valuation differences between buyer and seller, they may also affect the timing and amount of tax payable.

Understanding the tax consequences before signing the sale agreement helps avoid unexpected liabilities after completion.

Succession planning as an exit strategy

Not every exit involves selling to an external purchaser. Many owner-managed businesses are transferred to family members or existing management teams.

Succession planning allows owners to:

• Protect the long-term future of the business.
• Provide continuity for employees and customers.
• Transfer knowledge gradually.
• Reduce disruption during the ownership transition.

Where ownership is transferred rather than sold outright, additional tax considerations may arise, making professional advice particularly valuable before implementing the chosen strategy.

Common business exit planning mistakes

Many avoidable tax costs arise because planning begins too late.

Common mistakes include:

• Waiting until Heads of Terms have been agreed before seeking tax advice.
• Assuming Business Asset Disposal Relief applies automatically.
• Not reviewing the company’s trading status.
• Ignoring changes to share ownership before disposal.
• Choosing an asset sale without considering the overall tax consequences.
• Failing to review deferred consideration arrangements.
• Not retaining records supporting the acquisition cost of shares.

Most of these issues can be identified and addressed if planning starts well before the business is placed on the market.

Worked example: planning a successful business exit

Mark has owned a profitable engineering company for more than twelve years and plans to retire.

Rather than accepting the first offer received, he begins planning almost two years before marketing the business.

During this period he:

• Reviews his shareholding structure.
• Confirms the company qualifies as a trading company.
• Ensures he satisfies the qualifying conditions for Business Asset Disposal Relief.
• Updates financial records and resolves outstanding compliance matters.
• Obtains professional tax and legal advice before negotiations begin.

Because the transaction is carefully planned and structured as a share sale, Mark qualifies for Business Asset Disposal Relief on the first £1 million of qualifying lifetime gains, with any remaining gain taxed under the standard Capital Gains Tax rules.

Early planning enables him to maximise the after-tax value of the transaction while avoiding delays during due diligence.

Key takeaways

Business exit strategies should be developed long before a business is marketed for sale. Early planning provides time to review ownership structures, identify tax risks and confirm eligibility for valuable reliefs.

Effective business exit planning also helps business owners understand how the structure of a transaction influences business exit tax, whether selling shares or business assets is more appropriate and how Business Asset Disposal Relief can improve the final after-tax proceeds.

By planning ahead, keeping accurate records and reviewing the tax position before formal negotiations begin, business owners place themselves in the strongest possible position to achieve a successful and tax-efficient exit.

Case Study: Choosing the Right Exit Strategy Before Selling the Business

A business owner visited our Fulham Broadway office while considering different business exit strategies ahead of retirement. Although they had received interest from several buyers, they were unsure whether selling to a third party, completing a management buyout or selling only part of the business would provide the best commercial and tax outcome. They also wanted to confirm whether they qualified for Business Asset Disposal Relief (BADR) before entering formal negotiations.

We reviewed the company’s trading status, shareholding structure, financial records and long-term objectives before any Heads of Terms were agreed. After comparing the tax implications of the available exit options, we confirmed the conditions for Business Asset Disposal Relief, explained the differences between a share sale and an asset sale, and identified several areas that required attention before due diligence began. By planning the transaction early, the client entered negotiations with a clear strategy, improved buyer confidence and maximised the potential after-tax proceeds from the sale.
