✈️ New job, new city… new tax rules

If you’re in the U.S. on an H-1B, you’re moving from student/trainee rules into full employee territory. That means different forms, different rates, and FICA. This guide gives you the essentials—what you owe, which forms to file, and how to stay compliant—without the jargon.

🧭 H-1B in a nutshell

The H-1B lets professionals with specialty occupations work in the U.S. for up to 3 years (extendable to 6). Typical fields: STEM, healthcare, finance, architecture, IT.

💵 What taxes do H-1B holders pay?

Most H-1B employees pay a combined ~20–35% across:

  • Federal income tax (progressive brackets)

  • State income tax (0–~10%, depending on state)

  • Local/city tax (some jurisdictions)

  • FICA → Social Security 6.2% + Medicare 1.45% (your employer matches these)

📝 States without a wage income tax: AK, FL, NV, SD, TX, WA, WY.
NH & TN tax certain investment income, not wages.

🧮 Federal tax brackets (quick view)

You’re taxed at graduated rates. Most H-1B earners fall between 12–35% depending on income and filing status. (Your employer withholds throughout the year; the return reconciles the final amount.)🧑‍⚖️ H-1B tax residency: 1040 or 1040-NR?

Your tax residency drives everything:

  • Resident for tax purposes (most H-1Bs after arrival) → taxed on worldwide income, file Form 1040.

  • Nonresident for tax purposes (usually in your first partial year if you don’t meet the Substantial Presence Test) → taxed mainly on U.S.-source income, file Form 1040-NR.

🧮 Substantial Presence Test (SPT) — the rule of days

You’re a resident if you’re physically present in the U.S.:

  • 31+ days in the current year and

  • 183+ days using the weighted formula (all days this year + 1/3 of last year + 1/6 of the year before).

🎓 Coming from F/J status? Your earlier exempt years may not have counted toward SPT; once on H-1B, days typically do count.

🗂️ Forms & documents you’ll need

  • W-2 (wages & tax withheld)

  • Any 1099 (interest/dividends/contract income)

  • Social Security Number

  • Paystubs, address details (for state/local)

  • Visa timeline (entry dates for SPT)

  • If claiming certain credits (residents only): receipts for education, childcare, etc.

🧾 Filing as an H-1B: step-by-step

  1. Determine residency (SPT) → this decides 1040 vs 1040-NR.

  2. Gather forms (W-2/1099s).

  3. State returns: required if your state taxes wages; some cities do too.

  4. Multi-state? You may need to file in work state and home state; credits often avoid double tax.

  5. Filing deadline: April 15, 2025 (for 2024 income).

  6. Need time? File Form 4868 for an automatic extension to Oct 15 (extension to file, not to pay).

👥 Filing status, spouse & dependents (important nuances)

  • Nonresidents (1040-NR) generally cannot file jointly and cannot claim dependents (limited exceptions: Canada, Mexico, South Korea, and India students/apprentices for specific child credits).

  • Residents (Form 1040) may file jointly, claim dependents, and access broader credits/deductions.

  • Married mixed-status option: In some cases, you can elect to treat a nonresident spouse as a resident for a joint return (worldwide income then applies). Consider immigration/tax impacts before electing.

🧾 FICA on H-1B

You do pay Social Security (6.2%) and Medicare (1.45%) on wages (employer matches). Prior F/J exemptions don’t carry over to H-1B.

🏙️ Live in one state, work in another?

You may file in both. Many states grant a credit so you don’t pay tax twice on the same income. Keep residency and work location records tidy.

💡 Pro tips for an easy season

  • Check your W-4 at onboarding and after life changes (marriage, move, raise).

  • Track pre-tax benefits (401(k), HSA, FSA)—they lower taxable wages (resident rules).

  • Save paystubs and HR portal copies of forms.

  • If you can’t pay in full, file on time and consider an IRS installment plan (Form 9465).
