Introduction: Moving to Dubai as a US Citizen Is Not a Move to Zero Tax
Moving to Dubai from London removes UK income tax on your new salary, but it does not remove a single dollar of your United States tax obligation. Since 2024, a steady stream of bankers, fund managers and business owners has left Britain for the Emirates. For British citizens, the arithmetic is simple. For Americans, however, the picture is very different, because the IRS taxes its citizens wherever they live.
Moving to Dubai Changes Your UK Bill, Not Your US One
Moving to Dubai switches off most of your UK tax once you break residence properly. Meanwhile, your US Form 1040 continues exactly as before, with the same brackets, the same FBAR and the same Form 8938. Consequently, the relief you feel from leaving HMRC behind can hide a US bill that is now completely uncovered by foreign tax credits. In London, UK tax at 45% usually exceeded your US liability. In Dubai, by contrast, there is no local income tax to credit, so the IRS collects its full share.
Who This Guide Is For
This guide is written for US citizens and green card holders who live in the UK today and plan to relocate to the UAE. In particular, it suits senior employees moving with a bank or fund, founders relocating a business, and investors with UK property, pensions and portfolios they intend to keep. At TaxYork, we prepare the US and UK returns for this move every year, and the same mistakes recur. Therefore, we have set out the whole sequence below, from the UK exit to your first US return filed from the Gulf. Throughout, we assume you are moving to Dubai for several years rather than a short secondment, because the answers change sharply for a stay of under five years.
The US Side: Citizenship Taxation Follows You When Moving to Dubai
The United States taxes on citizenship, not residence. As a result, moving to Dubai simply changes the country printed at the top of your return. You still file Form 1040 every year, you still report worldwide income, and you still face the same penalties for missing deadlines. Americans abroad get an automatic extension to 15 June, although interest runs from 15 April.
There Is No US-UAE Income Tax Treaty
The United States has no comprehensive income tax treaty with the UAE. Consequently, no treaty article reallocates taxing rights, no tie-breaker helps you, and no treaty reduces US tax on your Dubai income. In London, the US-UK income tax treaty did a great deal of quiet work for you. After moving to Dubai, much of that protection falls away for new income, because the UAE has nothing equivalent with Washington. Furthermore, the US and the UAE have no social security totalisation agreement, which matters for anyone who becomes self-employed.
The Foreign Earned Income Exclusion and the Dubai Housing Limit for 2026
The main US relief for Dubai salary is the foreign earned income exclusion. For 2026, Revenue Procedure 2025-32 sets the exclusion at $132,900 per qualifying person. Additionally, the foreign housing exclusion covers rent above a base amount of $21,264. For Dubai specifically, IRS Notice 2026-25 raises the annual housing limit to $57,174, so the maximum housing exclusion is $35,910 for a full year. Abu Dhabi sits lower at $49,687. You can read how the IRS computes the exclusion in its guide to figuring the foreign earned income exclusion.
However, the exclusion is small relative to senior Gulf packages. A managing director earning AED 2,000,000, roughly $545,000 at the fixed 3.6725 peg, excludes perhaps $168,000 and pays full US tax on the rest. Moreover, the stacking rule taxes the remaining income at the rates that would apply if the excluded income were still included, so you do not restart at the 10% band.
Qualifying in the Year You Move
The exclusion needs either the bona fide residence test or the physical presence test. In the year you arrive, bona fide residence rarely works, because it requires an uninterrupted period covering a full tax year. Instead, most people rely on physical presence, which needs 330 full days outside the United States in any 12 consecutive months. Notably, days in London count as foreign days, because the test concerns presence outside the US, not presence in Dubai. Therefore, an American already living in the UK can often qualify from the first day after moving to Dubai, provided US visits stay short. For a plain-English overview, Investopedia's explanation of the foreign earned income exclusion is a useful starting point.
Planning the Timeline Before Moving to Dubai
The best time to plan is six to twelve months before moving to Dubai. By then, you know your start date, but you can still choose when to sell assets, when to vest or exercise awards and when to cut UK ties. For instance, an RSU tranche vesting a month before departure is UK-taxed employment income, while one vesting a month after moving to Dubai may be partly UK-taxable and partly not, depending on where you worked during the vesting period. Similarly, a bonus for the London year remains UK-sourced even when paid in Dubai. Therefore, map every payment date against your departure date first, then decide.
Your UK Foreign Tax Credits After Moving to Dubai
This is the planning point that almost every guide misses. Years of UK tax at 40% and 45% usually leave Americans in London with large foreign tax credit carryforwards. In the UK, those credits were stranded, because UK tax already exceeded US tax each year. After moving to Dubai, however, they suddenly become valuable.
Why Your Carryforwards Suddenly Have Somewhere to Go
Excess foreign tax credits carry back one year and forward ten years under section 904(c). A carryforward can only reduce US tax on foreign-source income in the same basket, and only up to the limitation computed on Form 1116. Salary for work performed in Dubai is foreign-source general-category income. Because the UAE levies no tax on it, the current-year limitation sits almost entirely unused. Consequently, your old UK credits can absorb US tax on your Dubai salary, sometimes for several years. We explain the mechanics further in our guide to the foreign tax credit carryforward for Americans leaving the UK.
FEIE or FTC: Choosing the Order
The order in which you use each relief matters enormously. If you elect the exclusion immediately, you shrink the income those carryforwards can offset, and the oldest credits keep expiring unused. Furthermore, once you elect the exclusion and later revoke it, you cannot re-elect for five years without IRS consent. Therefore, the usual answer for a high earner moving to Dubai with large carryforwards is to delay the exclusion, burn the expiring credits first, and elect the exclusion only once the credits run low. In our experience, for Americans moving to Dubai from senior London roles, this single decision is often worth more than $100,000 over the first three years.
US-Source Income the Credits Cannot Touch
Carryforwards only offset foreign-source income. Therefore, dividends from US companies, interest from US banks and gains on US securities remain fully taxable, whatever your credit position. Additionally, the 3.8% net investment income tax cannot be reduced by foreign tax credits at all. As a result, a large US brokerage portfolio produces a clean US bill after moving to Dubai, with no UK credit to lean on.
Leaving the UK Properly: SRT, Split Year and the Five-Year Trap
HMRC does not accept a one-way flight as proof that you are moving to Dubai for good. Instead, your UK position depends on the statutory residence test, the split-year rules and, crucially, how long you stay away.
Breaking UK Residence Under the Statutory Residence Test
The statutory residence test decides UK residence each tax year. HMRC's RDR3 guidance on the statutory residence test sets out three automatic overseas tests. If you were UK resident in any of the previous three years, you are automatically non-resident with fewer than 16 UK days. Alternatively, the full-time work abroad test allows fewer than 91 UK days, provided you average 35 hours a week overseas and work more than three hours in the UK on fewer than 31 days. Otherwise, the sufficient ties test counts family, accommodation, work, 90-day and country ties against your days.
Split-Year Treatment for the Departure Year
Without split-year treatment, you remain UK resident for the whole tax year in which you leave, and your early Dubai salary falls into the UK net. Case 1 covers leaving to work full-time abroad, while Case 3 covers ceasing to have any UK home. Notably, Case 3 needs the UK home to be sold or let on commercial terms, and you must then spend fewer than 16 days in the UK for the rest of that year. Our detailed guide to split-year treatment for Americans walks through each case.
The Temporary Non-Residence Trap
The five-year rule catches people who treat moving to Dubai as a short tax holiday. If you were UK resident in at least four of the seven tax years before leaving, and you return within five years, HMRC taxes certain gains and income in the year you come back. In particular, gains on assets you owned before departure, flexible pension withdrawals and some close company dividends are caught. Consequently, a large disposal made in Dubai is only safe from UK tax if you stay away for more than five full years. Our article on temporary non-residence for Americans covers the detail.
Telling HMRC You Have Left
If you file Self Assessment, you report departure on your return and claim split-year treatment in the residence pages. Otherwise, you can use HMRC's form P85 for leaving the UK to reclaim overpaid PAYE. In practice, most high earners moving to Dubai still file UK returns, because they keep UK property, directorships or other UK income.
UK Assets You Keep After Moving to Dubai
The UK-UAE double taxation convention, in force since 2016, decides what Britain can still tax. Meanwhile, the IRS taxes everything regardless. Therefore, each asset needs looking at twice.
A London Property You Let
Article 13(1) of the UK-UAE treaty lets Britain tax gains on UK land, and rental income remains UK-taxable too. Consequently, you join the non-resident landlord scheme, and your letting agent withholds basic-rate tax unless HMRC approves gross payment. From 6 April 2027, the UK property rates rise to 22%, 42% and 47%, and the withholding rate follows. Furthermore, a sale must be reported to HMRC within 60 days of completion, even with no tax due, under the rules for non-residents selling UK property. On the US side, the rent is reported on Schedule E, and the UK tax is creditable in the passive basket. We cover the dual computation in our guide to non-resident capital gains on UK property for US persons.
Importantly, Americans who hold only US citizenship have no UK personal allowance as non-residents. Consequently, UK tax starts at the first pound of rental profit.
UK Shares, Dividends and Interest
Article 13(5) gives gains on ordinary shares only to your state of residence. Therefore, after moving to Dubai and surviving the five-year window, a sale of your UK portfolio escapes UK capital gains tax entirely. Additionally, Article 10 exempts most UK dividends from UK tax for a UAE resident, and Article 11 gives UK interest paid to an individual exclusively to the UAE. From 6 April 2026, the UK also abolished the dividend tax credit for non-UK residents, so treaty protection matters more than before. However, the IRS still taxes every one of those dividends and gains, and none of them carries a foreign credit.
ISAs After You Leave
You can keep an ISA after leaving, but you cannot add new money once you are non-resident, as HMRC explains on its page about ISAs when you move abroad. The IRS never recognised the wrapper, so income and gains inside it stay taxable in the US before and after moving to Dubai. Furthermore, UK funds inside an ISA are usually PFICs. Consequently, the ISA becomes a pure US compliance cost with no UK benefit worth protecting.
UK Pensions and the UK-UAE Treaty
Article 17 of the UK-UAE treaty makes private pensions paid to a UAE resident taxable only in the UAE. Therefore, with a UAE tax residency certificate, you can claim UK pension income free of UK tax. The IRS, however, taxes that income in full. More subtly, the US-UK treaty's pension protections depend on treaty residence. Under Article 4(2) of the US-UK treaty, a US citizen living abroad is a US resident only if he or she has a substantial presence, permanent home or habitual abode in the United States. Consequently, after moving to Dubai, the Article 18 deferral that sheltered growth inside your SIPP while you lived in London may no longer be available, and that position needs specific analysis before you draw.
Dubai Compensation, Businesses and Social Security
Gulf packages offered to Americans moving to Dubai look simple, but several features interact badly with US rules. Therefore, read your employment contract through a US lens before you sign.
End-of-Service Gratuity and the FEIE Timing Rule
UAE labour law entitles most private-sector expatriates to an end-of-service gratuity. It is 21 days' basic salary for each of the first five years and 30 days for each later year, capped at two years' pay. However, the foreign earned income exclusion only covers pay received no later than the year after the services were performed, under Treasury Regulation section 1.911-3. Consequently, most of a gratuity earned over five or ten years falls outside the exclusion when it is finally paid. Instead, you need foreign tax credits to cover it, which is another reason to preserve your UK carryforwards.
Self-Employment Tax Without a Totalisation Agreement
The UAE does not appear on the IRS list of US totalization agreements. As a result, an American who consults or trades as a sole proprietor after moving to Dubai owes US self-employment tax. That is 12.4% up to the Social Security wage base plus 2.9% Medicare on all earnings. Moreover, the foreign earned income exclusion does not reduce self-employment tax at all. By contrast, in Britain a certificate of coverage kept you in one system only.
Owning a UAE Company: CFC and NCTI
Many founders moving to Dubai set up a UAE free-zone company. If you own more than 50% of it, it is a controlled foreign corporation. Under the rules introduced by the One Big Beautiful Bill Act, its profits fall into net CFC tested income each year, whether or not you draw them. UAE corporate tax is 9% above AED 375,000, and qualifying free-zone income can be taxed at 0%. Therefore, the high-tax exclusion, which needs a rate above 18.9%, rarely applies. Individuals who make a section 962 election reach the 40% deduction on Form 8993, an effective 12.6% rate, with a 90% deemed-paid credit. Our guide to the section 962 election for US owners explains the mechanics, which apply to UAE companies in the same way.
FBAR, Form 8938 and Missed Reporting When Moving to Dubai
Foreign account reporting follows you when moving to Dubai. Indeed, it often becomes more visible there, because UAE banks treat US customers with particular care.
UAE Banks Report You to the IRS
The UAE signed a Model 1 FATCA intergovernmental agreement with the United States on 17 June 2015. As a result, Emirates banks collect your US tax identification number and report your balances to the UAE Ministry of Finance under its FATCA and CRS programme, which passes them to the IRS. Consequently, the IRS will see your Dubai accounts whether or not you report them yourself.
Thresholds for Americans Living Abroad
You must file an FBAR with FinCEN if your foreign accounts together exceed $10,000 at any time in the year, as explained on the FinCEN FBAR page. Separately, Form 8938 applies to Americans living abroad above $200,000 at year-end or $300,000 at any time for single filers, doubled for joint filers. The IRS publishes a comparison of Form 8938 and FBAR requirements. Notably, the first year after moving to Dubai often doubles your account count, because you keep UK accounts while opening Emirates ones.
When the Move Exposes Old Gaps
Relocation paperwork often surfaces historic problems. For example, a Dubai bank's FATCA questionnaire, a mortgage application or an employer's tax equalisation review can reveal missed FBARs or unfiled returns from the London years. In our experience, it is far cheaper to regularise those gaps before moving to Dubai, while your UK records and advisers are still to hand. Our FBAR and FATCA reporting service handles both current and catch-up filings.
Case Study: A Managing Director Moving to Dubai From Canary Wharf
The following illustrative case uses realistic figures to show how the pieces fit together when moving to Dubai. Names and details are fictional.
The Facts
Ethan, 46, holds US citizenship only. He spent nine years as a managing director at a Canary Wharf bank before moving to Dubai on 1 February 2026 to run the bank's regional desk. His Dubai package is AED 2,000,000 a year, roughly $544,600. His years of UK tax left him with $210,000 of general-basket foreign tax credit carryforwards, of which $38,000 expires at the end of 2026. He keeps a let flat in London, a £800,000 share portfolio with a £300,000 gain, and a SIPP worth £1.4 million.
The US Position
For 2026, Ethan earns about $499,000 of Dubai salary plus $53,000 of January London pay. US tax on that income is roughly $157,000. His January UK PAYE supplies about $21,000 of current-year credit. Instead of electing the exclusion, we used $136,000 of carryforwards, including every dollar due to expire. As a result, his 2026 US income tax on salary is nil, and $74,000 of credits remain for 2027. Had he elected the exclusion, he would have excluded about $154,000, left $38,000 of credits to lapse, and locked in an election he could not cheaply reverse. We plan to elect the exclusion from 2028, once the credits run out.
The UK Position
Ethan left on 1 February 2026, so split-year Case 1 applies to 2025/26. Because he is not a British citizen, he has no personal allowance as a non-resident. The London flat produces £42,000 of annual profit, which costs £9,260 in UK tax for 2026/27 at 20% and 40%. From 2027/28, the new property rates lift that to about £10,100. HMRC approved him for gross rent under the non-resident landlord scheme, and the UK tax credits against US tax on the rent.
The Result
Ethan's portfolio gain is the sharpest lesson. Selling in London would have cost £72,000 of UK tax, about $95,000, plus $14,500 of US net investment income tax that no credit can offset. Selling after moving to Dubai, by contrast, costs only US tax of about $90,700, a saving of roughly $19,000. However, that saving only holds if he stays non-resident for more than five full tax years. Meanwhile, he leaves his SIPP untouched until his US treaty position is settled. Finally, he files FBAR and Form 8938 covering both UK and Emirates accounts.
How TaxYork Can Help
We prepare US and UK returns side by side for clients moving to Dubai, so the departure year is handled consistently in both countries. Specifically, our team models the FEIE-versus-credit order, prepares Form 1116 carryforward schedules, and files the split-year claim with your final UK return. Furthermore, we handle non-resident landlord registration, 60-day property returns, UK-UAE treaty pension claims and FBAR and Form 8938 filings. For your annual US filing, our US tax returns for expats service covers Form 2555, Form 1116 and CFC reporting. For treaty questions, our tax treaty optimisation team reviews pension and residence positions before you draw. Above all, we focus on comprehensive tax preparation and compliance, so every form is filed correctly and on time.
Conclusion
Moving to Dubai ends most of your UK tax, but it leaves your US tax untouched and strips away the UK credits that used to cover it. Therefore, the value of the move depends on planning done before you leave. That means breaking UK residence cleanly, choosing the right order for your old credits and the exclusion, and timing disposals around the five-year rule. It also means checking pensions, ISAs and Gulf compensation through a US lens. Handled properly, moving to Dubai can still cut your overall tax sharply. Handled carelessly, however, it produces a US bill you did not expect and reporting gaps the IRS already knows about.
