Leaving the US for Dubai: why moving does not end your tax bill

Most countries tax you because you live there. The United States taxes you because you are American. That single difference is why an American moving to Dubai is in a completely different position from a Briton or a German doing the same thing.

Moving does not end the obligation. It only changes which reliefs you can claim. And if you decide to end it properly, by giving up the citizenship, that is where the real money appears.

If you keep the passport: what actually changes

You file a US return every year, for the rest of your life, wherever you live. What Dubai gives you is a set of reliefs.

The foreign earned income exclusion. For 2026 it is 132,900 dollars per qualifying person. A married couple where both work and both qualify get it twice.

To qualify you need one of two tests:

• Physical presence: at least 330 full days abroad in a 12 month period. A full day is midnight to midnight. Days over international waters do not count, and you can choose where the 12 month window sits.
• Bona fide residence: an uninterrupted stay abroad covering a full calendar year. Short trips are fine. Telling the local authority you are not resident there, and avoiding local tax on that basis, kills the status.

The housing exclusion, and Dubai is treated generously. The general cap on allowable housing costs is 30 percent of the exclusion. Dubai and Abu Dhabi are listed as high-cost locations with their own, higher limits: 57,174 dollars a year for Dubai and 49,687 for Abu Dhabi. You carry a base amount yourself, 16 percent of the maximum exclusion.

What the exclusion does not cover. Dividends, capital gains, rental income and pensions. The exclusion is for earned income only. Above it, and beside it, the US taxes normally, and because the Emirates levy no income tax there is no foreign tax credit to offset against. That gap is the whole reason structuring matters here.

The 15.3 percent that catches self-employed Americans

Self-employment tax is 15.3 percent, 12.4 for Social Security up to the annual cap and 2.9 for Medicare with no cap at all. There is an extra 0.9 percent above 200,000 dollars for single filers.

Two things make this worse than people expect:

• Neither the income exclusion nor the housing exclusion reduces it. You can exclude your entire income from income tax and still owe the full 15.3 percent.
• There is no totalization agreement with the Emirates. The official list runs to 30 countries and contains no Gulf state. So nothing shifts the liability away, even though the UAE charges expatriates no social contribution of its own.

On the 2025 Social Security cap that is up to 21,836 dollars of Social Security tax, plus uncapped Medicare on everything above.

The usual answer, and its price. Wages from a foreign employer generally fall outside US social security. Being a salaried employee of your own UAE free zone company rather than a sole proprietor is therefore the clean route, because a UAE company is not an American employer. The cost is that the company becomes a controlled foreign corporation, with Form 5471 every year and a 10,000 dollar penalty per company per year for missing it. You trade a tax for a filing obligation with a hard penalty.

If you give up the citizenship: the expatriation tax

This is the part that decides whether leaving is expensive or ruinous.

You are a covered expatriate if any one of three things is true:

1. Average annual net income tax for the five years before you expatriate exceeds the threshold. 211,000 dollars for 2026, 206,000 for 2025. Note that this is tax paid, not income earned.
2. Net worth of two million dollars or more on the day you expatriate.
3. You cannot certify on Form 8854 that you met your US tax obligations for the previous five years.

Two observations that matter more than the numbers themselves.

The two million figure has never been adjusted for inflation. It has stood since 2008 while the income threshold rises every year. A house with equity and a well-fed 401k now gets people there without any sense of being wealthy.

The third trigger has no threshold at all. Miss a return, fail to certify, and you are a covered expatriate regardless of how little you own.

What the tax actually does. On the day before you expatriate, your entire worldwide estate is treated as sold at market value and the resulting gain is taxed. Against that you have an exclusion of 910,000 dollars for 2026, 890,000 for 2025, per person. A couple expatriating together each get their own, but each is tested separately.

The fee everyone gets wrong

Renouncing has to be done in person before a consular officer abroad. The administrative fee is 450 dollars.

It used to be 2,350. The State Department cut it by final rule dated 13 March 2026, effective 13 April 2026. Nearly every guide online still quotes the old number.

It is worth knowing, and it is also the smallest item on this page. The fee is not the cost. The expatriation tax is.

The 40 percent that lands on the people you leave behind

This is the item almost nobody includes, and it is the most expensive one.

If you leave as a covered expatriate, then a US person who later receives a gift or bequest from you pays a tax at the highest estate tax rate, 40 percent, on the value above the annual exclusion of 19,000 dollars for 2026. It is reported by the recipient on Form 708.

Read that again: the tax is paid by your American child, not by you, and it applies to anything received from 1 January 2025 onward. There is no expiry. Whatever you leave to an American, decades later, carries it.

This is the single strongest argument for making sure you are not a covered expatriate, including by fixing five years of filings before you renounce rather than after.

The reporting, and what missing it costs

Obligation	Trigger
FBAR, FinCEN Form 114	foreign accounts over 10,000 dollars combined at any point in the year
Form 8938	higher thresholds, and they are higher again for people living abroad
Form 5471	ownership of a controlled foreign corporation, penalty 10,000 dollars per company per year

Under FATCA your UAE bank reports you regardless of what you file, so the accounts are visible either way. If years are already missing, there are formal routes back into compliance, and using one of them is materially cheaper than being found.

The two state traps

Leaving the country is not the same as leaving the state.

California treats you as resident if you are domiciled there, and a domicile change needs all three of giving up the old one, actually moving, and showing intent through your behaviour. There is a safe harbour of 546 consecutive days abroad for an employment-related absence, with visits capped at 45 days a year.

The safe harbour has a trapdoor: it does not apply if investment income exceeds 200,000 dollars in any contract year. That is precisely what happens when someone sells shares or a business as part of the move. Lose the safe harbour and you are a California resident again, retroactively, on worldwide income. California also recognises neither the foreign tax credit nor the foreign earned income exclusion, so the federal exclusion has to be added back on the state return.

New York keeps your domicile until you prove otherwise with clear and convincing evidence, and registering to vote elsewhere is explicitly not enough. Separately, a permanent place of abode plus 184 days makes you resident regardless of domicile, and any part of a day counts as a full day.

Then there is the telework rule. If your employer’s main office is in New York and you work from elsewhere, those days count as New York days unless the employer has established a bona fide office at your location. Without that step, a salary earned from Dubai stays New York source income.

What this means in practice

There is no version of this where an American simply moves and stops dealing with the United States. There are two coherent positions, and picking one deliberately is worth more than any amount of optimisation.

Keep the passport. Accept annual filing, use the exclusions properly, be deliberate about the self-employment question, and get the state residency clean before anything is sold.

End it properly. Fix the five years of filings first so that the certification trigger cannot catch you, then look hard at the net worth test, and take the 40 percent charge on heirs seriously as part of the decision rather than as a footnote.

The UAE side of this is the simple half. A company, a residence visa, an Emirates ID, a corporate tax registration, all with published fees and fixed deadlines. You can work the cost out yourself in our company cost calculator.

We handle that half, the accounting, the tax registrations and the deadlines here. The American half belongs with a US international tax adviser who works with Forms 5471, 8854 and the FBAR regularly, and it belongs there before the move, not after.
