Moving from UAE to the US on H-1B: the complete tax transition guide

For Indians working in the UAE who transfer to the US on an H-1B — through an internal company move at Amazon, Microsoft, Google, or elsewhere, or through a new US employer — the tax transition is one of the most complex financial events you will face.

You go from one of the most tax-efficient environments in the world (UAE, zero income tax, zero capital gains tax) to one of the most comprehensive tax systems (US, worldwide income taxation, PFIC rules, FBAR requirements). And several things you own — Indian mutual funds, NRE FDs, UCITS ETFs, UAE savings — carry forward into the new tax environment with unexpected consequences.

This guide covers what to do before you leave the UAE, what changes on arrival, and how to structure the transition.

Pre-move checklist: 3–6 months before H-1B start date

1. Determine your US tax residency start date

The moment that matters is when you become a US tax resident, not when you arrive physically. You become a US tax resident when you pass the substantial presence test.

The substantial presence test counts:

• 100% of days in the US in the current year
• 1/3 of days in the prior year
• 1/6 of days in the year before that

If your H-1B start date is October 1, 2026 and you work in the US for the rest of the year (92 days), you have only 92 current-year days. Unless you had significant US days in 2025 and 2024 (which most UAE-based employees do not), you likely do NOT pass the substantial presence test in 2026 — making 2027 your first year as a US tax resident.

If your H-1B starts January 2, 2027, you will almost certainly pass the substantial presence test in 2027, making 2027 your first US tax resident year.

Why this matters: If you can time your move so you have a clear non-resident year before US tax residency begins, you have more time to clean up your Indian investments.

Action: Compute your substantial presence test dates carefully with your tax advisor before making any investment decisions.

2. Sell Indian mutual funds before US tax residency begins

This is the single most important pre-move action.

Indian mutual funds are PFICs from the moment you become a US tax resident. If you sell before that date, the gains are taxed under Indian rules only:

• LTCG on equity funds: 12.5% above ₹1.25L
• STCG on equity funds: 20%
• Debt funds: slab rate

If you sell after becoming a US tax resident, the PFIC excess distribution regime applies:

• Gain is allocated back to every year you held the fund
• Each year's gain is taxed at the highest US ordinary income rate (37% in 2026)
• Interest is charged on each year's tax as if it were overdue (≈8%/year)
• Effective total tax rate on a 5-year holding: 50%+

See the PFIC rules for H-1B Indians guide for the full worked example.

ELSS locked-in funds: ELSS has a 3-year lock-in from each SIP installment date. If units are still within the lock-in period, you cannot sell them. For these units, make the Mark-to-Market (MTM) election as early as possible after becoming a US tax resident to stop the interest accumulation on future gains.

Action: Target selling all unlocked Indian mutual fund units — equity, debt, hybrid, index funds — before the first day of US tax residency. Pay Indian capital gains tax at the applicable Indian rate. Reinvest proceeds in US investments after arrival or in NRE FDs pending arrival.

3. Understand your NRE/NRO account obligations

Your NRE and NRO accounts can stay open — H-1B holders are FEMA non-residents and can maintain NRE/NRO accounts.

What changes:

• NRE interest: Tax-free in UAE. Tax-free in India. Taxable in the US as ordinary income once you are a US tax resident. Report annually on Schedule B.
• NRO interest: Taxable in India (30% TDS). Also taxable in the US — claim foreign tax credit (Form 1116) to avoid double tax.
• FBAR: Both accounts must be disclosed on FinCEN 114 if combined foreign account balances exceed $10,000 at any point in the year.
• Form 8938: Both accounts must be disclosed on Form 8938 if total foreign assets exceed $50,000 (year-end) or $75,000 (any point) for single filers living in the US.

Action: No structural changes needed to accounts before the move. After arriving, set up Schedule B and FBAR reporting from Year 1. Do not let NRE FDs roll over into longer tenors once you know you are moving — keep them short so they mature before or shortly after your move.

4. Handle UCITS ETFs

If you accumulated UCITS ETFs (CSPX, VWRA) during UAE years through IBKR:

• UCITS ETFs are not US-situs assets, so no US estate tax issue (this was the reason to hold them as a UAE NRI)
• As a US tax resident, UCITS ETFs are not PFICs — they are traded on a foreign exchange but the underlying is public securities in an exchange-traded fund, and the IRS has generally not applied PFIC rules to exchange-traded UCITS ETFs in the same manner as Indian mutual funds
• However, UCITS ETFs are PFIC candidates under a technical reading — they satisfy the passive income test. Whether to maintain UCITS ETFs on H-1B or convert to US-listed equivalents (SPY, VTI) is a decision you should make with a cross-border CPA
• If you convert to US-listed ETFs, you lose the estate tax protection (US-listed ETFs are US-situs) — but as a US resident, the estate tax exemption is $13.61M, so estate tax is no longer a concern unless you are extremely wealthy
• Practical answer for most UAE-to-US movers: Sell UCITS ETFs before becoming a US tax resident and buy US-listed ETFs (SPY, VTI, QQQ) after arriving. No PFIC issue, full US market access, no estate tax concern as a US resident.

5. Review UAE bank accounts

UAE bank accounts (Emirates NBD, ADCB, Mashreq, etc.) are foreign financial accounts for FBAR purposes once you are a US tax resident.

• Interest earned in UAE bank accounts after you become a US tax resident is US taxable
• UAE bank accounts must be disclosed on FBAR
• If your UAE salary continues for a few months after H-1B starts (overlap period), that income and any interest accrued in UAE accounts is US taxable

Action: Plan to close UAE bank accounts once you no longer need them post-move. Keep only what you need for final UAE obligations.

The dual-status year: your year of arrival

In the year you pass the substantial presence test, you have a dual-status — NRA for the part of the year before you became a US tax resident, US resident after.

What this means for tax filing

• You file a dual-status tax return (Form 1040 with statement for NRA period)
• Income earned while NRA (UAE salary for part of year) is generally not US taxable
• Income earned while US resident is US taxable on worldwide basis
• Standard deduction is generally not available in dual-status year; you use itemized deductions
• Dual-status returns are complex — budget for a CPA who handles international returns

First-year election: electing to be treated as US resident for full year

You can elect to be treated as a US tax resident for the entire year (not just from substantial presence date), if:

• You were not a US tax resident in the prior year, AND
• You are a US tax resident on December 31 of the election year

This first-year election (Section 7701(b)(4)) means you report worldwide income for the full year — which is generally worse if you had significant UAE salary in the early part of the year. Most UAE-to-US movers do NOT make this election — the dual-status return is more beneficial because UAE salary for the first part of the year escapes US taxation.

Consult a CPA before making or not making this election.

After arrival: first-year US tax obligations

From Day 1 as a US tax resident

• All worldwide income is US taxable — including any remaining NRE FD interest, UAE bank interest (if accounts still open), and Indian investment income
• RSU vests at your US employer are W-2 income
• File FBAR by April 15 for any year where combined foreign account balances exceeded $10,000

Indian mutual funds still held at arrival

If you arrive as a US tax resident and still hold Indian mutual funds (could not sell in time, or ELSS in lock-in):

Option A: Sell immediately Pay the PFIC excess distribution tax. Painful, but stops future accumulation.

Option B: Make the Mark-to-Market (MTM) election File Form 8621 with your first US tax return. Under MTM, you include unrealized gain at year-end as ordinary income, but no back-interest is charged on future years. This stops the clock from compounding.

Do not do nothing — not making an election while holding Indian mutual funds leads to the worst outcome: excess distribution regime on eventual sale with full back-interest.

Social Security and Medicare tax (FICA)

H-1B holders are subject to US FICA taxes (Social Security 6.2% up to the wage base; Medicare 1.45% with no cap). Unlike F-1 students who are exempt from FICA for 5 years, H-1B holders pay FICA from Day 1.

India and the US do not have a totalization agreement, so contributions made during UAE/India years do not credit toward US Social Security benefits.

Pre-move timeline

Phase 3: returning to India after US H-1B employment

Many UAE-to-US H-1B workers eventually return to India — after a green card application stalls, after the US tenure ends, or by choice. This creates a third phase with its own distinct tax treatment.

RNOR status: the re-entry buffer

When you return to India after significant time abroad (including both UAE and US years), you typically qualify for RNOR (Resident but Not Ordinarily Resident) status for up to 2 financial years. RNOR status applies if:

• You have been a non-resident of India for 9 of the preceding 10 financial years, OR
• You have been in India for 729 days or fewer in the preceding 7 financial years

During the RNOR period, foreign-source income — income from sources outside India — is not taxable in India. This is the critical point for returning professionals with US assets:

Foreign income exempt during RNOR:

• Capital gains on US stocks sold from your US brokerage account
• Dividends on US stocks received during RNOR period
• Rental income from US property
• Interest from NRE FDs (if not yet reclassified to resident account)

Schedule FA during RNOR: not required

A significant administrative relief: Indian tax residents who are RNOR do not need to file Schedule FA (foreign asset disclosure) for foreign assets. Schedule FA is mandatory only for ordinary residents. During your RNOR years, your US brokerage account, 401(k), and US bank accounts do not need to be disclosed in Schedule FA.

This changes the moment you transition from RNOR to ordinary resident — typically in Year 3 after return. At that point, Schedule FA disclosure of all foreign assets becomes mandatory annually.

401(k) and IRA from US employment

Your US retirement accounts (401k, Traditional IRA, Roth IRA) do not disappear when you leave the US. Key considerations for Indian returnees:

While RNOR: Distributions from 401k/IRA are foreign-source income — not taxable in India during RNOR. However, the US may still withhold 30% US tax on distributions to non-residents (NRAs). The India-US DTAA Article 20 covers pensions — you may be able to claim a reduced rate under the treaty.

After RNOR (ordinary resident): 401k/IRA distributions become globally taxable in India. India taxes them as income; the India-US DTAA provides for the elimination of double tax, but the interplay between Indian slab rates and US withholding requires careful planning. Do not leave significant 401k distributions until after RNOR ends.

Roth IRA: India does not recognize Roth IRA's tax-exempt status. Even though qualified Roth distributions are US tax-free, they are taxable in India for ordinary residents. Consult a CPA with both US and India expertise before taking Roth distributions as an Indian resident.

Practical action: Consider taking larger 401k/IRA distributions during RNOR years when the distribution is India-tax-free. This accelerates tax-advantaged account drawdown at the most favorable Indian tax point.
