American expats in the UAE face a unique paradox: you live in a tax-free country but still owe US taxes on worldwide income. FATCA means most non-US banks and brokers view you with suspicion (or refuse you outright). PFIC rules make foreign mutual funds a tax nightmare. Roth IRAs, 401(k)s, and FEIE all have UAE-specific implications. This guide untangles all of it.
Key takeaways
- -US citizens and green card holders owe US tax on worldwide income, even while living in the UAE.
- -The Foreign Earned Income Exclusion (FEIE) can exclude up to $130,000 of earned income from US tax.
- -PFIC rules make investing in non-US mutual funds and ETFs extremely tax-inefficient. Stick to US-domiciled funds.
- -FATCA reporting: you must file FBAR (FinCEN 114) if your foreign accounts exceed $10,000 at any point.
- -Interactive Brokers is one of the few major brokers that accepts US persons living abroad.
Your US tax obligations from the UAE
The US is one of only two countries that taxes based on citizenship, not residency. As a US citizen or permanent resident, you owe US tax on your worldwide income regardless of where you live. The UAE tax-free environment helps (no local taxes to deal with), but Uncle Sam still wants his share.
You must file a US tax return every year. The key exclusions and credits that reduce your bill:
Foreign Earned Income Exclusion (FEIE): excludes up to approximately $130,000 (2026, indexed for inflation) of foreign earned income. You qualify via the Physical Presence Test (330 days outside the US in a 12-month period) or the Bona Fide Residence Test.
Foreign Housing Exclusion: covers reasonable housing costs above a base amount. In Dubai, where rent is high, this can be a significant additional exclusion.
These only apply to earned income (salary, self-employment). Investment income (dividends, capital gains, interest) is not excludable under FEIE.
PFIC rules: why you cannot buy foreign ETFs
Passive Foreign Investment Company (PFIC) rules are the single biggest trap for US expats. Any non-US mutual fund, ETF, or investment trust is classified as a PFIC. This includes UCITS ETFs (VWCE, IWDA) that every other nationality uses.
PFICs are taxed punitively: gains are taxed as ordinary income (not capital gains) plus an interest charge that compounds over the holding period. A 10-year holding of a PFIC can result in an effective tax rate of 50%+.
The solution: stick to US-domiciled ETFs (VOO, VTI, VXUS, BND). Yes, they have 30% dividend withholding for non-US persons, but you are a US person. You pay US rates, and you report everything on your regular return.
Do not let a well-meaning non-US advisor put you into UCITS ETFs. The tax consequences are severe.
Brokerage options for US expats in the UAE
Most non-US brokers refuse US persons due to FATCA compliance costs. Your options are limited:
Interactive Brokers: the best option. Accepts US persons globally, gives access to US exchanges, and handles FATCA reporting. You can hold US-domiciled ETFs and manage your portfolio normally.
Charles Schwab International: accepts US expats. Limited product range compared to IBKR but a simpler interface. Good for a buy-and-hold ETF portfolio.
Saxo does NOT accept US persons. eToro does NOT accept US persons for securities trading. Most local UAE brokers do not accept US persons.
Keep your existing US brokerage accounts (Fidelity, Vanguard, Schwab domestic) if you can. Some will let you keep the account but restrict new deposits when you update your address to a foreign one.
IRAs, 401(k)s, and retirement accounts
Roth IRA: you can only contribute if you have US-taxable earned income. If your FEIE excludes all your earned income, your taxable earned income is zero, and you cannot contribute. Some expats choose not to claim FEIE on the first $7,000 to enable Roth contributions.
Traditional IRA: same earned income requirement. Contributions are tax-deductible if you do not have access to an employer plan.
401(k): if you have a US employer or a US-based remote job, you may still have access to a 401(k). Otherwise, your existing 401(k) remains invested and grows. Do not cash it out early (10% penalty plus income tax).
HSA: Health Savings Accounts require a US high-deductible health plan. You likely lose access to contributions when you move to the UAE, but existing HSA funds remain invested.
FBAR, FATCA, and reporting requirements
FBAR (FinCEN 114): if your aggregate balance in all foreign (non-US) financial accounts exceeds $10,000 at any point during the year, you must file an FBAR electronically by April 15 (with automatic extension to October 15). This includes UAE bank accounts, brokerage accounts, and even signatory authority on business accounts.
FATCA (Form 8938): if your foreign financial assets exceed $200,000 at year-end (or $300,000 at any point) for single filers living abroad, you must attach Form 8938 to your tax return. Thresholds are higher for married filing jointly.
Penalties for non-filing are severe: up to $10,000 per account per year for FBAR, plus potential criminal penalties. FATCA penalties start at $10,000 and can reach $60,000.
Most foreign banks will report your account details to the IRS under FATCA anyway. Non-reporting is not a viable strategy.
