For many entrepreneurs, selling their business is the financial event that defines their long-term wealth position. After years — sometimes decades — of building value, the sale crystallises that value into liquid capital. How that capital is taxed, and how it is then invested and managed, determines whether the exit truly delivers the financial freedom it promises.
For entrepreneurs who live abroad, are planning to move abroad, or are non-domiciled in the UK, there are additional layers of planning opportunity and complexity. The difference between an optimal and a suboptimal exit structure can be measured in seven figures for a significant business sale.
The UK Tax Baseline: Capital Gains Tax on Business Sale
A UK-resident, UK-domiciled individual who sells their business (whether through a share sale or an asset sale) pays Capital Gains Tax on the gain — the difference between the sale proceeds and the original cost base.
Business Asset Disposal Relief (BADR): Formerly known as Entrepreneurs' Relief, BADR reduces the CGT rate to 18% on qualifying gains up to a lifetime limit (currently £1 million, significantly reduced from the previous £10 million limit). Note: the BADR rate was 10% until April 2025, 14% in 2025/26, and increased to 18% from 6 April 2026. To qualify, you must have:
- Owned at least 5% of the company's shares
- Been an officer or employee of the company
- Held the shares for at least 2 years immediately before the sale
The BADR lifetime limit means that for business sales generating gains above £1 million — common for any modestly successful business — BADR only shelters the first million. Gains above the BADR limit are taxed at the standard CGT rate (currently 24% for higher/additional rate taxpayers).
Asset sale vs. share sale: In a share sale (you sell your shares to the buyer), CGT applies to the gain on your shares. BADR may apply. In an asset sale (the company sells its assets to the buyer, then the company is wound up and proceeds distributed to shareholders), there may be both corporate tax on the asset sale gains at the company level AND CGT/income tax on the distributions to shareholders. Share sales are generally preferred by sellers for this reason; buyers sometimes prefer asset sales for commercial reasons.
The Role of Residency in Business Exit Tax
The UK does not tax non-residents on capital gains from selling shares in most UK private companies — with important exceptions. Non-residents selling UK shares are generally not subject to UK CGT on the gain.
However:
- If the company's value derives primarily from UK land or UK property (the "property-rich" rule), the gain may be within UK CGT scope even for non-residents.
- If you were UK-resident when you built up the gain but become non-resident just before realising it, the temporary non-residence rules may attribute the gain back to a UK-taxable year.
The temporary non-residence rules: If you leave the UK and return within 5 years, gains you realise while abroad may be taxed as if you were still UK-resident when you made them. This prevents a simple "move abroad, sell shares, return to UK" tax avoidance strategy.
The 5-year window: If you genuinely leave the UK and remain non-resident for more than 5 complete tax years, the temporary non-residence rules do not apply, and gains realised during that period should not be subject to UK CGT (subject to the property-rich exception).
For entrepreneurs considering a business sale, the question of whether departure from the UK occurred at least 5 years before the sale date is therefore highly material. Planning a move abroad shortly before a business sale — hoping to escape UK CGT — requires very careful advice; the temporary non-residence rules are more complex than the headline suggests.
Non-Domiciled Entrepreneurs and Business Sales
The remittance basis for non-domiciled UK residents was abolished from 6 April 2025 and replaced with the four-year Foreign Income and Gains (FIG) regime. Under the FIG regime, individuals who have not been UK-resident in the 10 years before arriving can elect to pay no UK tax on foreign income and gains for their first four tax years of UK residence.
For entrepreneurs who were previously relying on the remittance basis to keep offshore gains out of UK CGT, those rules no longer apply. Anyone who arrived before 6 April 2025 and exhausted their four FIG years is now taxed on worldwide income and gains in the normal way.
For UK-resident individuals selling a UK-incorporated company, the gain arises on a UK-sited asset and is within UK CGT regardless of any FIG election. For an individual within their four-year FIG window selling shares in a genuinely non-UK company, the gain may qualify for the FIG exemption if properly claimed. Specialist UK tax advice is essential before completing any such sale.
Pre-Sale Restructuring: Getting the Structure Right Before the Sale
The optimal time to plan for a business exit is well in advance of the sale itself — ideally 2-3 years before, when options are still open and HMRC's anti-avoidance rules are less likely to disrupt planning.
Common pre-sale planning steps include:
EMI options and employee share ownership: Ensuring that any employee share option schemes are structured as Enterprise Management Incentive (EMI) schemes preserves BADR eligibility for option holders and can reduce CGT costs on a sale.
Extracting retained profits before sale: If the company has built up retained profits that are no longer needed in the business, extracting them before sale (as dividends or pension contributions) may reduce the sale price — and therefore the CGT base — while the extracted funds are taxed at lower rates than they would be as part of a lump-sum gain.
Pension contributions from the company: An employer pension contribution reduces company profits (and therefore corporation tax), reduces the retained cash that inflates the sale price, and puts money into a tax-exempt pension wrapper. For business owners approaching a sale, maximising pension contributions before sale is often a priority.
Investment portfolio business property relief: If the business qualifies for Business Property Relief (BPR) for IHT purposes, and you intend to retain shares rather than sell, this may affect estate planning more than the sale itself — but it is worth understanding before deciding to sell.
The holding company structure: In some cases, interposing a holding company between the business owner and the trading company (a "Newco" structure) before a sale can provide flexibility — for example, allowing proceeds to be invested in new businesses using a Capital Gains Tax reinvestment relief (Business Asset Rollover Relief), or facilitating a share-for-share exchange. These structures must be set up in advance and with HMRC clearance where appropriate.
Post-Sale Wealth Management: Deploying the Proceeds
The sale is the beginning of a new challenge: what do you do with a large capital sum? Common mistakes include:
Leaving large amounts in cash for too long. A business sale often produces 8-10 figures of cash. Leaving it in current accounts for months while you "work out what to do" is both costly (inflation erosion, bank deposit limits, missed investment time) and risky (deposit protection limits do not cover large balances; bank failures, while rare, do happen).
Concentrating in one asset class. The instinct after selling a business is often to buy property — a familiar, tangible asset. Replacing one large, illiquid, single-asset concentration (the business) with another (one or two properties) does not achieve diversification.
Underestimating the tax efficiency of the initial deployment. The year of the sale is often a year of high income. Making maximum pension contributions, establishing offshore bonds, considering the charitable giving options — all of these are more powerful in the year of sale than in subsequent years when income is lower.
Moving too quickly into complex structures. Post-sale is often when promoters of aggressively marketed tax schemes target recently liquid entrepreneurs. HMRC has been consistently successful in challenging such schemes. Legitimate tax planning is not the same as artificial schemes that lack genuine commercial substance.
Relocating After the Sale: The Tax Residency Timeline
Many entrepreneurs sell their business and then choose to relocate — often to a lower-tax jurisdiction (Cyprus, UAE, Portugal have all been popular). The timing matters:
If you are still UK-resident at the point of sale, UK CGT applies regardless of subsequent plans.
If you leave the UK and then sell within 5 years, the temporary non-residence rules may apply — specialist advice is essential before the sale.
If you sold the business while genuinely non-resident (having left the UK more than 5 years earlier), UK CGT should not apply to the gain on a non-property-rich company — though the detailed analysis of your specific position must be done by a qualified UK tax adviser.
