Moving to Dubai As a UK Tech Founder: What Happens To Your Salary, Dividends And Business Sale?

There’s no personal income tax in the UAE, and for many UK founders, that’s a major attraction of moving to Dubai but relocating doesn’t automatically remove your UK tax obligations, particularly if you continue to own and run a UK company.

Many founders retain their UK businesses, work remotely from Dubai, draw salaries, receive dividends and eventually sell their shares. Each of these transactions has different UK tax rules, and getting the timing wrong can be expensive.

To explain how the rules work, let’s follow Sarah, a UK tech founder who moves to Dubai but continues to own and work for her UK limited company.

Becoming Non-Resident Under The Full-Time Work Abroad Test

The full-time work abroad test makes you non-resident for an entire tax year providing that you satisfy the following criteria during a tax year period (from 6 April to 5 April):

• You are employed or self-employed
• You work at least 35 hours per week overseas
• You exercise a workday overseas for more than three hours every 31 days
• You are present in the UK at midnight on no more than 90 days
• You exercise no more than 30 workdays in the UK

Example: Sarah works remotely for her UK company in Dubai. She visits the UK every quarter for a week working 5 out of the 7 days. Total UK midnights = 28 and total UK workdays = 20. She is non-resident under full-time work abroad.

Leaving Partway Through The Tax Year: Split-Year Treatment

If you leave part way through a tax year, case 1 enables you to exit the UK tax system from the day you start full-time work abroad. You need to satisfy criteria in the tax year of departure and you must be in full-time work abroad for the entire following tax year i.e. split year requires a two-tax year plan.

Example: Sarah starts working from Dubai on 1 October 2026. To be eligible for split year treatment, she needs to satisfy criteria from 1 October 2026 to 5 April 2027 and from 6 April 2027 to 5 April 2028.

How Is Your UK Employment Income Taxed While Working From Dubai?

A common misconception is that receiving a salary from a UK company automatically makes it taxable in the UK. The source of employment income is where you physically exercise work duties and therefore, work duties exercised in the UK are taxable and work duties exercised overseas are not taxable.

Example: Sarah’s salary is £100,000. She works 20 days in the UK and 200 days in total so £10,000 (or 10%) is taxable in the UK and £90,000 (or 90%) is not taxable in the UK.

What Happens To Bonuses Paid After Leaving The UK?

Bonus income is sourced to the period that the bonus was earned. A bonus that was wholly earned whilst resident in the UK is wholly taxable in the UK, even if it is paid after you left.

A bonus that was partially earned whilst resident and partially earned whilst non-resident will have split taxation rules. The resident portion will be wholly taxable and the non-resident portion will be split between UK workdays and total workdays with HMRC being able to tax the UK workday portion only.

Example: Sarah received a bonus of £100,000 earned during TY 2026. Sarah was resident for 6 months and non-resident for 6 months. Sarah worked 10% in the UK during the non-resident period. The UK taxable portion of the bonus is £55,000 split as follows: £50,000 in the resident period (£100,000 x 50%) and £5,000 in the non-resident period (£100,000 x 50% x 10%).

Can Founders Receive UK Dividends Tax-Free In Dubai?

For many founders, dividends are where the move can produce particularly significant personal tax savings.

UK dividends received by an entire year non-resident are treated as disregarded income which limits tax on dividend income to tax deducted at source. At the time of writing, no tax is withheld at source on dividend income and as such, you can extract an unlimited amount of dividend income (subject to company profits) and pay £0 UK tax.

Example: Sarah is non-resident for the entire 2027/28 tax year and her UK company pays her £100,000 of dividend income. No tax is deducted at source, so UK tax on the dividend is nil. The full £100,000 comes out free of UK tax, and with no personal income tax in the UAE, she keeps all the £100,000, as long as she doesn’t return within 5 years of leaving.

The disregarded income rules only apply for a tax year in which you’re non-resident for the whole year. They don’t apply to the overseas part of a split year, so a dividend Sarah takes between 1 October 2026 and 5 April 2027 is taxed in the UK as normal. The timing of dividends around your departure can make a big difference to the overall tax outcome.

Can You Sell Your UK Company Without Capital Gains Tax?

The potential tax savings can be even more significant where a founder plans to sell their business.

As a non-resident, share gains from a UK company are outside the scope of capital gains tax. The main exception is a UK property-rich company, one that gets 75% or more of its value from UK land, where you’ve held 25% or more of the company at any time in the 2 years before the sale. Most tech companies get their value from software, IP and customers rather than property, so this rarely applies.

Example: Sarah sells her UK company shares in June 2027 generating a £2 million gain. As she is non-resident, there is no UK capital gains tax at the point of sale. This is with the caveat of a return to the UK within 5 years.

The Five-Year Rule: What Happens If You Return To The UK?

If you were UK resident in 4 of the 7 tax years before you left and you come back within 5 years, some incomes and gains received during the overseas period are taxed in the year you return to the UK.

Dividends paid from close companies and share gains from assets acquired pre-departure fall within the scope of these rules. Employment income does not fall within the scope of these rules. To avoid triggering the rules, you must be non-resident for more than five years.

Example: Sarah moves back to the UK in summer 2030, less than 4 years after leaving. Her 2027/28 dividend income of £100,000 and her £2 million share gain are both taxed in the 2030/31 tax year as if they arose that year under the temporary non-resident rules.

How Do You Notify HMRC That You Have Left The UK?

Once you have moved, you should make sure your departure is correctly reported to HMRC. There are two routes, as follows:

1. Through a P85 form which enables you to get an NT tax code to receive employment income gross of taxation (noting that UK tax still applies on UK workdays); or
2. Through SA109 supplementary pages on a self-assessment tax return.

As a starting point, you are not generally required to submit detailed evidence of non-residence with your departure notification. However, HMRC can request evidence to substantiate your position.

Founders should therefore maintain accurate records of their travel dates, UK midnights, overseas working hours and UK workdays, together with relevant employment and company records.

Dubai offers significant personal tax advantages for UK tech founders, particularly when it comes to salary, dividends and selling a business but the move needs to be structured correctly.

Becoming non-resident is only the starting point. The timing of your departure, where you physically work, how your company is managed, when dividends are declared and whether you eventually return to the UK can all influence the final tax outcome.

Getting the UK side right before you leave is what allows you to benefit from the opportunities Dubai offers without unexpected tax liabilities years later.
