Financial Planning After Selling a Business: What to Do With a Life-Changing Sum

For most business owners, the sale of their business is the single largest financial event of their lives. After years or decades of personal sacrifice, the company that consumed their time and identity is sold, and what arrives in the bank account can be a sum larger than anything they have ever managed directly.

What happens next matters enormously. A well-navigated post-sale transition preserves and grows that wealth. A poorly navigated one — characterised by hasty reinvestment, tax mistakes, emotional decisions, or identity crisis — can erode it substantially.

The Immediate Aftermath: Don't Rush

The most important financial advice for the weeks immediately following a sale completion is to do very little.

This sounds counterintuitive. You have a large sum arriving in your account. There is pressure — internal and external — to "do something" with it: invest it, buy something, help family members, start a new venture.

Resist this pressure.

The period immediately following a business sale is not the time for large, irreversible financial commitments. It is the time for:

1. Ensuring the sale proceeds are safe. Large cash deposits should be spread across multiple FSCS-protected banks (up to £85,000 per authorised institution per depositor). In the short term, consider a money market fund or short-duration gilt fund for the bulk, which offers safety and a meaningful return while you take time to plan.

2. Understanding your tax position. Before the proceeds arrive, engage a tax adviser if you have not already done so. Business Asset Disposal Relief (BADR) rules are complex, and the self-assessment filing deadline for CGT is important (see below).

3. Taking six to twelve months to develop a proper financial plan. This is the only large sum you are likely to receive in your life. The cost of a few months' additional planning — compared to making irreversible commitments under emotional pressure — is trivially small.

Business Asset Disposal Relief (BADR): How It Works

BADR (formerly Entrepreneurs' Relief) reduces the rate of Capital Gains Tax on qualifying business disposals to 18% for 2026/27, up to a lifetime limit of £1 million in qualifying gains. (The rate was 10% until April 2025, 14% for 2025/26, and 18% from 2026/27 onwards.)

To qualify for BADR, the following conditions must generally have been met for at least two years ending on the date of disposal:

• You were an officer or employee of the company.
• You held at least 5% of the ordinary share capital and voting rights.
• You were entitled to at least 5% of the distributable profits and assets on a winding up.

Note: the lifetime limit was reduced from £10 million to £1 million in March 2020. For business owners who took entrepreneurs' relief before that date, the current residual limit depends on prior claims.

Gains above the BADR lifetime limit are taxed at the standard CGT rate (18% or 24% in 2026/27 depending on rate band). For a £5 million sale with £1 million BADR limit, the maths are: £1 million at 18% (BADR rate for 2026/27) = £180,000 tax; £4 million at 24% = £960,000 tax. Total tax: approximately £1.14 million.

CGT Self-Assessment Timing

Capital gains on the sale of a business are reported and paid via Self Assessment:

• For most assets (including shares in private companies), the CGT is due by 31 January following the end of the tax year of disposal.
• This means gains realised in the 2025–26 tax year (ending 5 April 2026) are not due until 31 January 2027. This provides a meaningful window for planning, though interest accrues if payment is deferred beyond this date.

Residential property disposals have a different, accelerated payment-on-account regime (60 days), but this does not apply to business share sales.

Understanding the timing allows for planning around cash flow, instalment arrangements if proceeds are structured over time, and potential interaction with pension contributions that might reduce the tax liability.

Rebuilding a Financial Life from Scratch

For the typical business owner, their balance sheet before exit was heavily concentrated: the business was worth £X million, they owned a house, they had some cash, and perhaps a modest pension. The business represented 80-90% of their total wealth — a massive concentration risk that most professional investors would never tolerate.

Post-sale, for the first time, the founder has the opportunity to build a genuinely diversified, professionally managed portfolio. This is an exciting — and unusual — opportunity.

Risk Profile: Likely Different From Your Business Risk

Running a private business involves extreme concentration risk, illiquidity, and personal liability. Business owners who say they are "high risk" investors often mean this in a business context. For financial portfolio risk, many post-exit founders actually want far less volatility than they think — the security of the capital is psychologically more important now that it is no longer in their control.

A thorough risk-profiling process — exploring actual risk tolerance through scenario modelling, not just questionnaires — is essential before building the portfolio.

Portfolio Construction Principles

A post-exit portfolio for a 55-year-old entrepreneur with a £5 million post-tax sum might look roughly like:

• Two to three years of income needs in cash/short-duration bonds. This provides psychological security and prevents forced selling in a market downturn.
• Core diversified equity. A blend of global equity (passive, low-cost), with some tilt towards income-generating or quality-factor strategies depending on income needs.
• Alternative assets. Infrastructure, private credit, listed real assets — these add diversification and income without full equity correlation.
• Property. Buy-to-let or commercial property if appropriate, but balanced against the tax position and management demands.
• Pension. Annual Allowance contributions (£60,000/year gross in 2026); consider carry forward of unused allowances from prior three years, which for a business owner who made no pension contributions may allow a very large immediate contribution.

Using Pension Contributions After Exit

Many business owner-managers have accumulated little pension, having preferred to keep money in the business. Post-exit is the ideal time to fund a pension aggressively:

• Contributions of up to £60,000 gross per year qualify for income tax relief at the marginal rate.
• Carry forward rules may allow contributions of up to £180,000 in a single year if the prior three years' allowances were unused.
• For a 45% taxpayer, a £60,000 pension contribution costs only £33,000 net. The money also falls outside the estate for IHT purposes (until 2027, when the rules change).

The Psychological Challenge

Research consistently finds that 70–90% of entrepreneurs experience significant psychological difficulty in the year following a business exit. The business was not just a financial asset — it was an identity, a source of purpose, structure, and status. Its absence creates a vacuum that money cannot fill directly.

Common manifestations include: restlessness, seeking to reinvest in another venture quickly (often unwisely), depression, relationship strain, and a feeling of purposelessness. Financial advisers working with post-exit clients who ignore this dimension provide incomplete service.

Practical considerations:

• Give yourself a defined "decompression" period before making major financial commitments.
• Engage in genuine reflection on what you want from the next chapter — not just financially.
• Be cautious of being approached by people wanting your money. Post-exit founders are well-known targets for speculative investment opportunities.
• Consider philanthropy. Many founders find purpose in structured giving, which also provides IHT benefits.

Income Planning Post-Exit

Having left the business, you no longer have a salary. Your income must come from your portfolio. Planning this transition — ensuring a reliable, inflation-linked, sustainable income — is central to post-exit financial planning:

• Drawdown from portfolio. What sustainable withdrawal rate (typically 3–4% per annum adjusted for inflation) does your portfolio support?
• Annuity as income floor. A guaranteed annuity for some portion of essential income eliminates longevity risk and sequence-of-returns risk for that portion.
• State pension. Ensure your National Insurance record is complete (or make voluntary contributions if there are gaps) to maximise your state pension from age 67.
