Stock Options & RSUs: F1 to H1B Tax Planning

Stock options and RSUs — the basics

Most tech company H1B offers include equity compensation:

• RSUs (Restricted Stock Units): Shares granted, vest over time, taxed as ordinary income when they vest
• Stock options (ISOs / NSOs): Right to buy shares at a fixed price. Tax treatment varies.
• ESPP (Employee Stock Purchase Plan): Buy company stock at a discount (usually 15%)

How RSU taxation changes F1 → H1B

F1 OPT period

• RSUs that vest while you're on F1 OPT (non-resident alien status): taxed at flat 30% withholding by the employer (non-resident rate)
• No payroll taxes (FICA exempt)

H1B period

• RSUs that vest on H1B: taxed at your ordinary income rate (22-37% depending on income)
• FICA applies: additional 7.65% for employee portion

For most tech workers, the H1B rate is actually lower than the flat 30% non-resident rate — especially if your income is in the 22-24% bracket.

The tax situs issue (most people miss this)

When RSUs vest, part of the income may be "allocated" to the period when you were a non-resident vs. resident. This is called source allocation and affects which country can tax the income.

Example: 4-year RSU grant starting F1 OPT year 2. By H1B year 2, the RSUs are 50% vested in each status. The US can tax 100% (as you're a resident now), but India may also claim the F1-period portion. Form 1116 (foreign tax credit) prevents double taxation.

ISO (Incentive Stock Options) timing for F1 → H1B

ISOs have favorable tax treatment: no ordinary income tax at exercise (just AMT), and long-term capital gains rate on sale if you hold 2+ years from grant date and 1+ year from exercise.

Strategy: If you have ISOs, exercise them during F1 years when your income is low. This sets a low AMT base and starts your 1-year holding clock. By H1B, you may be selling at LTCG rates (0-20%) vs. ordinary income (22-37%).

ESPP for F1 → H1B transitions

ESPP discount (15% at most companies) is ordinary income at purchase. If you sell immediately ("disqualifying disposition"), you pay ordinary income tax on the discount.

No special treatment for F1 vs H1B — same taxation. But: ESPP contributions are post-tax, so FICA applies during H1B period on the full contribution.

W-2 Box 12 and RSU reporting

RSU income usually appears in Box 12 of your W-2 with code "V" (for stock options) or is already included in Box 1 (wages). Verify with your employer's equity team — misreported RSU income is common and the IRS matches it.
