A practical, UK-focused guide to handling the proceeds from selling your business, minimising tax with Business Asset Disposal Relief (BADR), and planning your financial future.

So, you’ve sold your business or are planning your exit—congratulations. But what comes next can be just as challenging: turning your hard-earned proceeds into lasting wealth. Managing the money from a business sale isn’t as simple as cashing a cheque. You’ll face complex UK tax rules, including Capital Gains Tax and the nuances of BADR, alongside big decisions about investing, succession, and your own financial security. This guide gives you the full picture—how to keep more of what you’ve built, avoid common traps, and lay the groundwork for life after business.
When you sell all or part of your business in the UK, the profits you make are usually subject to Capital Gains Tax (CGT). This tax applies to the increase in value from when you acquired your business (or business asset) to the point of sale. For many business owners, this will be the most significant tax bill they ever face. It’s essential to get it right, as mistakes or missed opportunities can cost you tens or even hundreds of thousands of pounds.
CGT is charged on the ‘gain’—that is, the difference between what you sell your business for and your base cost (what you paid for it, plus allowable costs such as legal fees or improvements). The current rates for individuals (2026/27) are 10% for basic rate taxpayers and 20% for higher or additional rate taxpayers when selling most business assets. However, if your sale includes residential property, a higher rate of 18% or 24% may apply on that portion.
There’s also an annual exempt amount—the first £3,000 of gains (2026/27) is tax-free. However, for most business sales, your gain will far exceed this. If you own your business through a limited company, you’ll usually sell your shares or the company may sell assets and distribute the proceeds. Each route has different tax consequences and it’s vital to understand these before you sign any sale agreement.
According to HMRC, Capital Gains Tax receipts exceeded £16.7 billion in 2022/23, a record high, reflecting increasing business exits and property sales.
It’s also worth noting that if you’re a company owner selling shares, and the company is trading (not an investment vehicle), you may qualify for Business Asset Disposal Relief (BADR), which can dramatically reduce your CGT bill. However, the rules around BADR are strict and must be met exactly—more on this below.
Business Asset Disposal Relief (BADR) is a valuable relief that can reduce your CGT rate on qualifying gains to just 10%, up to a lifetime limit of £1 million. Previously known as Entrepreneurs’ Relief, the rules were tightened in 2020, but BADR remains one of the most significant tax-saving tools for business owners exiting their company.
To qualify for BADR, you must have owned the business (or shares in a personal company) for at least two years before the sale. For company shareholders, you must be an employee or office holder, own at least 5% of the company’s ordinary share capital, and have at least 5% of the voting rights. The company must be a trading company (or the holding company of a trading group) throughout the qualifying period.
BADR is claimed via your self-assessment tax return for the year you sell your business or shares. It’s not automatic—you must tick the relevant boxes and provide supporting calculations. The relief applies to the first £1 million of gains across your lifetime, so if you’ve used part of this allowance already, only the remaining balance is available. Gains above this threshold are taxed at the standard CGT rates. If you miss the eligibility conditions, even by a day, you could lose access to this valuable relief.
Review your company structure and shareholdings at least two years before a planned sale to maximise your chances of qualifying for BADR. HMRC will not grant relief if you fall short of the strict criteria.
| Condition | Requirement for BADR |
|---|---|
| Ownership period | At least 2 years prior to sale |
| Shareholding | At least 5% of ordinary shares and voting rights |
| Employment | Must be an employee or office holder |
| Company type | Trading company or holding company of a trading group |
| Lifetime limit | £1 million of qualifying gains |
There are nuances—for example, BADR can apply to the disposal of business assets after cessation if the assets are sold within three years, and there are specific rules for partnerships and joint ventures. If you have complex arrangements, get professional advice early, as HMRC will scrutinise claims closely.
While BADR is the main relief for business owners, there are other strategies to reduce your CGT liability. Timing is often crucial. For example, you might stagger your sale over more than one tax year to make use of multiple annual exemptions or to stay within the basic rate band for a portion of your gain, thus reducing your average tax rate.
Gift Hold-Over Relief can apply if you give away your business assets (such as passing the business to a family member). This defers the CGT until the recipient disposes of the asset. Rollover Relief allows you to defer CGT if you reinvest the proceeds in new business assets, though this is less common when fully exiting. Investors’ Relief is another, but it’s typically aimed at external investors rather than founders.
For company owners, the decision between selling shares (which may qualify for BADR) and selling the company’s assets (potentially two layers of tax: corporation tax on the company, then CGT on extracting funds) can make a huge difference. It’s vital to model both scenarios with an adviser before proceeding. Don’t forget the impact of using your spouse’s allowances—transferring shares or assets in advance can double the use of BADR and tax-free allowances, but must be planned well before the sale.
Once heads of terms are signed, your options to restructure or split proceeds are severely limited. Start planning at least 18–24 months before a likely sale to maximise reliefs and avoid expensive mistakes.
Don’t try to shoehorn your business sale into a tax planning scheme that feels too clever. HMRC is quick to challenge arrangements it considers artificial or primarily tax-driven, and penalties can be severe. Stick to tried and tested strategies and always document your rationale for any actions taken.
Suddenly having a seven- or eight-figure sum in your account is both exciting and daunting. Your first instinct might be to pay off your mortgage or treat yourself, but the larger challenge is ensuring that money works for you over the long term. Many business owners underestimate how quickly a lump sum can be eroded by inflation, poor investment choices, or unexpected liabilities.
The first step is to establish a clear financial plan. This should include an honest assessment of your future needs—retirement, children’s education, charitable giving, or even starting another venture. Most wealth managers recommend holding back a cash buffer (typically 1–2 years’ living expenses) in a high-interest savings account or National Savings & Investments products to cover unforeseen costs and provide peace of mind.
The remainder should be invested according to your risk tolerance, time horizon, and goals. For most, this means a diversified portfolio spanning UK and global equities, bonds, property, and alternative assets. Pension contributions, ISAs, and other tax shelters can help reduce ongoing tax on investment gains. Don’t overlook the benefit of professional advice: a good wealth planner will help you avoid costly mistakes and keep your investments aligned with your objectives.
The Financial Services Compensation Scheme (FSCS) covers up to £85,000 per FCA-authorised institution. If your proceeds exceed this, spread them across multiple banks to ensure protection.
Avoid rushing into large investments or locking up funds in illiquid assets (like buy-to-let property) without a full financial review. The best portfolios are tailored to your circumstances, not just the highest headline returns. Consider your ongoing income needs, potential care costs, and how you would support your dependents if your circumstances changed.
Many business owners are so focused on CGT and the sale itself that they overlook the next big tax bill: Inheritance Tax (IHT). When you die, your estate (including the proceeds from your business sale) could be subject to 40% IHT on amounts above your nil-rate band (£325,000 as of 2026/27, plus an extra £175,000 main residence nil-rate band if you pass your home to direct descendants).
Crucially, some business assets are eligible for Business Relief, reducing or eliminating IHT while you own them. However, once you’ve sold and converted these assets into cash, this relief is lost. That means a business exit can suddenly expose your wealth to IHT in a way it wasn’t before, making timely estate planning essential.
There are a range of strategies to mitigate IHT after your exit: gifting assets during your lifetime (gifts become exempt after seven years), setting up trusts, making use of pension death benefits (which can pass outside your estate if structured correctly), and investing in certain IHT-efficient products. Each has pros and cons, and the right mix will depend on your family circumstances, intentions, and appetite for complexity.
Selling your business removes Business Relief on those assets—acting quickly to restructure your estate can save your heirs significant tax.
| Estate Value | IHT Rate | Nil-Rate Band |
|---|---|---|
| Up to £325,000 | 0% | Nil-rate band |
| £325,001–£500,000 | 0% on main residence if passed to direct descendants | Residence nil-rate band applies |
| Above allowances | 40% | Excess subject to standard IHT |
Don’t forget to update your will and lasting powers of attorney after a major liquidity event. The structure that made sense when you owned a business may not be optimal once your wealth is in cash or investments. Professional legal and tax advice is essential here—mistakes can be irreversible and very expensive for your family.
Selling your business is a life-changing event, but it’s also a time when people make costly mistakes. One of the biggest is failing to seek professional tax or financial advice until after the deal is done. By then, your ability to claim reliefs or structure the transaction tax-efficiently is severely limited. Another is underestimating how much money you’ll need for the rest of your life—many underestimate inflation and rising living costs, especially over a 20–30 year retirement.
Some owners are tempted by aggressive tax avoidance schemes or high-pressure investment pitches promising guaranteed returns. The UK has seen high-profile collapses and scams in recent years, with many ex-business owners among the victims. Stick to FCA-regulated advisers, avoid anything that sounds ‘too good to be true’, and remember that HMRC’s anti-avoidance rules are far-reaching and vigorously enforced.
Another mistake is failing to consider the emotional impact of a business exit. Many owners find the transition from running a business to managing wealth isolating or unsettling. Take time to plan your post-exit life, whether that’s new business ventures, charitable work, or simply enjoying more time with family. The wealth you’ve created is a tool—what matters is what you do with it.
Major business exits often trigger HMRC scrutiny. Keep thorough records of shareholdings, valuations, and relief claims for at least six years after your sale.
Failing to meet tax and reporting deadlines after your business exit can result in penalties and unnecessary stress. Your CGT liability must be reported via your self-assessment tax return for the tax year in which the sale occurred. The deadline for online filing is 31 January following the end of the tax year (e.g., a sale in July 2024 must be reported by 31 January 2026). Paper returns are due earlier (31 October).
You must pay any CGT due by the same deadline—missing this will result in interest and possibly penalties. If your sale involved UK residential property, you may need to report and pay CGT within 60 days of completion (under separate rules introduced in 2020), even if you also report it on your self-assessment return.
For BADR claims, ensure all supporting documentation is retained—share registers, board minutes, employment contracts, and evidence that the company was a trading company. HMRC can and does ask for proof, especially for larger claims. Keep these records for at least six years, and ideally longer for complex cases.
| Action | Deadline | Notes |
|---|---|---|
| Self-assessment return (online) | 31 January after tax year | Report gains and claim BADR |
| CGT payment | 31 January after tax year | Ensure funds are available |
| Paper self-assessment | 31 October after tax year | Earlier deadline than online |
| UK residential property CGT return | 60 days from completion | Separate obligation if relevant |
| Document retention | 6 years minimum | Keep all evidence of relief claims |
Set up calendar reminders for key tax dates, and request confirmation from your accountant when returns are filed and payments made. This avoids nasty surprises and late payment penalties.
