Leaving the UK for Dubai Before You Sell Your Company: Will It Really Save Tax?

For UK business owners with a sale on the horizon, the idea is appealing: move to the UAE, sell the company as a non-resident and keep far more of the proceeds. It can work. It also goes wrong more often than people expect. Three questions decide the outcome: are you genuinely non-resident, how long do you stay away, and when does the sale happen.

Why the UAE attracts sellers

The UAE does not charge personal income tax or capital gains tax on individuals. A UK owner who becomes non-UK resident before selling may therefore pay no UK capital gains tax on the sale and no UAE tax on the gain either.

Set that against a sale as a UK resident, where gains on shares are taxed at up to 24%, or 18% on up to £1 million of lifetime gains with Business Asset Disposal Relief. On a large sale the difference can be very significant.

Question one: are you really non-resident?

Leaving the country does not automatically end your UK tax residence. Your status for each tax year is set by the statutory residence test, which weighs:

• How many days you spend in the UK.
• Whether you work full time abroad.
• Your UK ties, such as family, accommodation, UK work and days spent here in earlier years.

The more ties you keep, the fewer days you can safely spend in the UK. Owners who keep a family home here, stay closely involved in the business or visit often can find that they remain UK resident despite moving.

The year of departure matters too. Split year treatment can divide a tax year into a UK part and an overseas part, but only when specific conditions are satisfied.

Question two: how long do you stay away?

This is where many plans come unstuck. Under the temporary non-residence rules, if you return to the UK after five years or less of non-residence, gains you realised while abroad on assets you owned before leaving are taxed in the year you return.

Put simply, selling your company in your second year in Dubai and coming back in your fourth could leave you with a UK tax bill on the sale after all.

Similar rules can reach large dividends from your own company where they are paid out of profits built up before you left.

Question three: when does the sale happen?

Even with a genuine move, timing needs care.

• Contracts signed before departure. For capital gains tax, the disposal date is usually the date of an unconditional contract, not completion. If the contract is signed while you are still UK resident, the gain may be taxed here.
• Earn-outs and deferred payments. These raise questions about when the gain arises and how it is taxed.
• Business Asset Disposal Relief. It is irrelevant if no UK tax is due, but if the plan fails you may have lost the chance to claim it on the right basis.

Other points to check

• Where your company is run from. If you manage the business from Dubai, it could become tax resident in the UAE or create a taxable presence there. Board meetings and decision-making need planning.
• UAE requirements. You need genuine residence in the UAE and local advice on its rules, including UAE corporate tax if you set up companies there.
• Inheritance tax. Leaving the UK does not end your exposure to UK inheritance tax at once. Since April 2025 it has depended on long-term residence, and it can follow you for some years after departure.
• Your family. A spouse who stays in the UK, children in UK schools and a UK home all count as ties.

Is the move worth it?

For some owners the saving easily justifies it, particularly those who truly want to live in the UAE for the long term. For others, the cost, disruption and risk of the plan failing make it much less attractive than it first appears.

What does not work is a short move made only to sell a company tax free. It exposes you to the five-year rule and close attention from HMRC, and could leave you with a sale taxed with less relief than you would have had if you had stayed.
