India-to-US H1B Holders: Equity-Compensation Tax Planning

A software engineer from Bangalore on an H1B visa at a Bay Area tech company has been in the US for six years. She has $450K of vested RSUs, 2,000 unvested RSUs, and an Indian Mutual Fund account she kept open at ICICI Prudential for investments in India. She is considering whether to extend H1B, apply for green card, or return to India within the next two years.

Each path has different equity consequences. No US-India totalization agreement means double social contributions on US wages and any Indian salary. PFIC rules make Indian mutual funds a tax nightmare. Returning to India as an RNOR (Resident Not Ordinarily Resident) has a brief favorable window before full Indian tax residency attaches. US trailing tax on post-departure RSU vests continues to apply.

The planning is dense because each country treats equity differently, and the lack of a full social security agreement adds cost.

No US-India totalization: the double social security problem

The US and India negotiated but never ratified a totalization agreement. The practical consequence: an Indian national working in the US on H1B typically pays:

• US FICA (6.2% Social Security + 1.45% Medicare, plus 0.9% Additional Medicare on wages over thresholds).
• Indian PF (Provident Fund) if still enrolled at the Indian employer (most H1B workers on US payroll are not on Indian payroll, so this often zeros out).

The common pattern: Indian employer suspends PF contributions during US assignment. US FICA applies fully. No credit for US FICA in India when computing Indian tax or future PF obligations. Lost Indian PF credits for the US period affect eventual Indian retirement benefits.

On return to India, the worker re-enrolls in PF. The gap years do not count for PF vesting or EPS (Employee Pension Scheme) service.

Some large Indian IT employers maintain “shadow” PF contributions for US assignees at modest levels to preserve service; others do not. The worker’s planning should confirm which.

PFIC rules on Indian mutual funds

IRC §§1291-1298 (PFIC rules) apply to any foreign corporation where:

• 75%+ of income is passive (interest, dividends, gains), OR
• 50%+ of assets produce passive income.

Indian mutual funds, even equity mutual funds, are foreign corporations under US tax law that typically meet the PFIC test.

PFIC consequences without election:

• Distributions are taxed at the top ordinary-income rate plus interest charges calculated from the purchase date.
• Sale of PFIC shares produces ordinary income, not capital gain, with interest charges.
• Losses are deferred, not currently deductible.

The tax is punitive by design. Effective rates on Indian mutual fund gains can exceed 50-60% for a long-held position once interest charges are included.

Three elections can mitigate:

1. QEF (Qualified Electing Fund) election: taxes current income annually as passed through. Requires fund to provide PFIC Annual Information Statement. Few Indian mutual funds provide this.

2. Mark-to-market election (§1296): annual recognition of unrealized gain as ordinary income. Available only for “marketable” PFICs; Indian mutual funds generally qualify.

3. Pedigreed QEF: election made in first year of PFIC ownership before any distributions. If not made at year one, more complex rules apply.

Practical guidance: sell Indian mutual funds before becoming a US tax resident, or within the first year of residency under favorable election. Holding PFICs without election is expensive.

Form 8621 filings

Each PFIC requires an annual Form 8621, even with no income event. A US resident with three Indian mutual fund positions files three Form 8621s per year.

Form 8621 captures:

• Election status.
• Distributions received.
• Calculated gains with applicable interest charges.

Penalty for failure to file Form 8621 is not explicitly set by statute but is part of the “delinquent international information return” family and can trigger the IRS’s streamlined-filing procedure for correction.

The RNOR window: Resident Not Ordinarily Resident

An Indian national returning to India from abroad qualifies for RNOR status for 2-3 years under Indian tax law (Section 6 of the Income-Tax Act 1961). RNOR status means:

• Indian tax applies only to Indian-source income.
• Foreign-source income (US RSU vests, US wages) is generally not taxed in India during the RNOR period.

To qualify for RNOR:

• Non-resident (not in India for 182+ days) for 9 of the last 10 years, AND/OR
• In India for less than 729 days in the last 7 years.

An Indian national who returns to India after 6 years of US work typically qualifies for RNOR for 2 years.

This creates a planning window. RSU vests during the RNOR period can be US-taxed (for US-source portion) but not India-taxed. Capital gains on stock sales during RNOR may not be India-taxable (check specific rules).

Strategic moves during RNOR:

1. Time RSU vests and stock sales to fall within RNOR where possible.
2. Exercise US NSOs before full resident status re-attaches.
3. Accelerate any plans to exit the US and be in the RNOR window during significant equity events.
4. Do NOT buy Indian mutual funds during RNOR (will become PFIC-exposed when US 1040 still required as RA).

The US taxation continues during RNOR period because exit from US does not stop US trailing tax on US-source income. But India’s claim is limited during RNOR.

Planning before leaving the US

A typical H1B holder returning to India should consider, in the 12 months before departure:

1. Exercise vested ISOs/NSOs if economically sound.
2. Sell US employer stock to lock in US treatment (including capital gain rates, basis).
3. Sell any PFIC holdings while US-resident (QEF or MTM election covers it).
4. Close US brokerage accounts that will not work cross-border.
5. Obtain Indian PAN card or update it (required for Indian tax filings).
6. Plan the exit date to maximize RNOR window effectiveness.

For green-card holders considering return who trigger §877A expatriation: the exit-tax analysis applies separately. See the trailing-tax article for details.

Indian tax on US RSU income after return

Once RNOR expires and full Indian tax residency attaches, the worker files Indian returns on worldwide income. Previously-vested US RSUs sold while Indian-resident produce:

• Indian capital gains on the sale (India-India sourcing rules apply).
• US capital gains on the sale if still held at US basis through US brokerage.
• FTC for US tax against Indian tax.

India and US have a tax treaty (1989) with FTC provisions under Article 25. The credit mechanics work, but the calculations require careful matching.

Comparison: key Indian vs US timings

Event	US treatment	India treatment (RNOR)	India treatment (full RA)
US RSU vest while in US	US income, withholding	Not taxable (outside India)	Not applicable (still US-resident)
US RSU vest while in India, post-return	US source (trailing)	Not taxable	Taxable (worldwide income)
US stock sale while in US	US capital gain	No Indian tax	Not applicable
US stock sale while in India, RNOR period	US capital gain	No Indian tax	Not applicable
US stock sale while in India, post-RNOR	US capital gain (NRA rules)	Indian capital gain	Indian capital gain
Indian mutual fund sale while in US	PFIC rules, punitive	Indian CGT	Not applicable

Frequently asked

Can I keep my US 401(k) after returning to India? Yes. The 401(k) remains tax-deferred under IRC rules. Distributions after return are US-taxable (withholding applies); India treats distributions per tax treaty.

What about my US brokerage account? Most US brokerages allow foreign-resident accounts but with restrictions. Some close the account if you become a non-US person. Confirm with your broker well before departure.

Do I need to file FBAR after leaving? FBAR applies to US persons (citizens, residents, green-card holders) with foreign accounts. Once you fully expatriate or lose green card, FBAR no longer applies.

Can I use the US-India treaty to reduce taxes on RSU vests after return? The treaty allows FTC mechanics but does not eliminate either country’s taxation. The result is that you pay the higher of the two rates effectively, not zero.

Is it worth staying in the US longer for tax reasons? Depends on your specific equity position. If you have significant unvested equity and Indian PFIC exposure, tax costs of premature return can be substantial. Model your specific situation.

Next step

If you are an Indian national with US equity planning a potential return to India, sit down with a dual-qualified Indian-US tax advisor. Start with an inventory of all Indian and US holdings including PFIC positions. Model three scenarios: stay in US, return within RNOR, return without RNOR. Identify the actions (PFIC sales, exercise decisions, departure timing) that produce the best total tax outcome across both countries.
