The UK's non-dom tax regime is being scrapped from April 2025. If you're an agency founder considering a move to Dubai, this changes everything about how your UK income and gains are taxed.

The remittance basis after 2025 non-dom reform is straightforward: it no longer exists for anyone who becomes UK resident after 6 April 2025. For founders already in the UK using it, there's a two-year transition period. But for anyone planning a move to Dubai, the old planning strategies around offshore income and capital gains are gone.

Let me explain exactly what changes, what stays the same, and what you should be doing now if Dubai is on your horizon.

What Was the Remittance Basis?

The remittance basis was a tax status available to UK residents who were not domiciled in the UK. It meant you only paid UK tax on UK-source income and gains. Your foreign income and gains were only taxed if you "remitted" them, brought them into the UK.

For agency founders moving to Dubai, this was historically very attractive. You could earn dividends from your UK agency, pay UK tax on that. But your Dubai-based investment income, overseas property gains, or foreign dividends could sit offshore tax-free, provided you didn't bring the money into the UK.

That changes from 6 April 2025.

What Changes From April 2025

The remittance basis after 2025 non-dom reform is replaced by a residence-based system. The key change: new UK residents get a four-year exemption on foreign income and gains, but only if they haven't been UK resident in any of the previous ten tax years.

After that four-year window, you're taxed on your worldwide income and gains, just like any other UK resident. No remittance basis. No deferral. No option to keep foreign income offshore untaxed.

For a founder moving from Dubai to the UK after April 2025, the calculation is simple:

  • First four years: no UK tax on foreign income and gains, but you lose this if you bring money into the UK
  • After four years: worldwide taxation on all income and gains, wherever they arise

There is no option to elect into the old remittance basis. It is gone for new arrivals.

What About Founders Already Using the Remittance Basis?

If you're already UK resident and using the remittance basis before April 2025, you get a transitional period. For the 2025/26 and 2026/27 tax years, you can still use the remittance basis on foreign income and gains that arose before 6 April 2025.

But any foreign income or gains arising from 6 April 2025 onwards are taxed on the arising basis, meaning you pay UK tax on them in the year they arise, regardless of whether you bring the money to the UK.

This is a significant change for founders who have built up offshore investment portfolios or property holdings while using the remittance basis.

What This Means for Agency Founders Moving to Dubai

If you're an agency founder planning to move to Dubai, the remittance basis after 2025 non-dom reform affects you in two scenarios:

Scenario 1: You move to Dubai and become non-UK resident. If you genuinely leave the UK and become non-resident (typically by spending fewer than 16 days per year in the UK, or 46 days if you've been resident for fewer than 3 years), then the remittance basis is irrelevant. You're taxed on UK-source income only. Your Dubai income is Dubai-taxed, not UK-taxed.

Scenario 2: You move to Dubai but retain UK residence. This is where the reform bites. If you spend too many days in the UK, or retain a UK home, you remain UK resident. And from April 2025, if you haven't been non-resident for ten years, you get no foreign income exemption at all. Your Dubai earnings become UK-taxable immediately.

This is a trap many founders fall into. They think "I'm based in Dubai" but their lifestyle, UK home, UK school runs, UK board meetings, keeps them UK resident. Under the new rules, that mistake becomes very expensive.

UK Property and Investment Planning After the Reform

For founders moving to Dubai, the remittance basis after 2025 non-dom reform has specific implications for UK property and investments.

UK Property

If you own UK property while living in Dubai, the tax treatment depends on whether you're UK resident or non-resident:

  • Non-resident: you pay UK tax on rental income (20% basic rate, no personal allowance unless you elect). Capital gains on UK property are taxable from day one, even as a non-resident.
  • UK resident: you pay UK tax on worldwide income, including any Dubai earnings. The old option to keep foreign income offshore and only pay tax on UK property income is gone.

For founders who planned to use the remittance basis to shield foreign income while owning UK property, that strategy no longer works from April 2025.

Investment Portfolios

If you have offshore investment portfolios, Dubai-based funds, international stocks, foreign property, the new rules mean you need to think about the tax impact differently:

  • If you're non-resident, no UK tax on these (but check local Dubai tax rules)
  • If you're UK resident, you're taxed on worldwide gains and income from day one after the four-year window

The four-year exemption for new residents does give some breathing room. But you cannot use it to shelter income indefinitely. After year four, you're on the arising basis for everything.

Practical Steps for Agency Founders

Here is what I recommend to agency founders considering a Dubai move, given the remittance basis after 2025 non-dom reform:

1. Get your UK residence status right. This is the single most important factor. If you genuinely leave the UK, you become non-resident and the remittance basis reform doesn't affect your Dubai income. But you must meet the statutory residence test. Keep a day-count diary. Avoid maintaining a UK home. Limit UK visits to fewer than 16 days per year (or 46 days if you've been resident for fewer than 3 of the last 4 years).

2. Review your UK property holdings. If you plan to keep UK property while living in Dubai, consider the tax implications on rental income and future capital gains. You may want to restructure ownership into a company or trust, but get professional advice, the rules are complex.

3. Consider your investment portfolio structure. If you're UK resident and approaching the end of your four-year exemption window, you may want to realise gains before the arising basis kicks in. Or consider moving investments into tax-efficient wrappers like ISAs (if you're eligible) or pensions.

4. Plan your exit timing. If you're already using the remittance basis and planning to move to Dubai, the transitional period (2025/26 and 2026/27) gives you two years to remit pre-2025 foreign income and gains at potentially favourable rates. Don't waste that window.

5. Speak to an ICAEW-qualified accountant. At Agency Founder Finance, we work with agency founders across the UK and Dubai. The remittance basis after 2025 non-dom reform is a significant change, but it doesn't have to derail your plans. It just means you need to be more deliberate about your structure.

Common Questions About the Remittance Basis Reform

Can I still use the remittance basis if I move to Dubai after April 2025?

No. If you become UK resident for the first time after 6 April 2025, the remittance basis is not available. You get the four-year foreign income exemption instead, but that's a different mechanism with different rules.

What happens if I'm already using the remittance basis and then move to Dubai?

If you leave the UK and become non-resident, the remittance basis stops applying because you're no longer UK resident. Your UK-source income (like agency dividends) remains UK-taxable, but your Dubai income is Dubai-taxed. The reform mainly affects those who remain UK resident.

Does the reform affect my UK agency's structure?

Not directly. Your UK agency pays corporation tax as normal. The reform affects your personal tax position as a founder, how your dividends, salary, and personal investments are taxed. If you're moving to Dubai, you may want to review your shareholding structure and dividend timing.

What about the four-year exemption, can I use it to avoid tax on Dubai income?

Yes, for the first four years of UK residence, provided you haven't been UK resident in any of the previous ten tax years. But after four years, you're on the arising basis. And you cannot remit the income to the UK during the exemption period without triggering tax.

Final Thoughts

The remittance basis after 2025 non-dom reform is a major shift for UK tax planning. For agency founders moving to Dubai, the key takeaway is this: if you genuinely leave the UK, the reform doesn't affect your Dubai income. But if you remain UK resident, even while living partly in Dubai, the old strategies of keeping foreign income offshore are gone.

Get your residence status right. Plan your property and investment structure early. And work with accountants who understand both UK and Dubai tax systems.
