How to file taxes as an H-1B visa holder was the question Alex Rivera faced in his first April in the United States. He had been working for eight months, his employer had been withholding taxes from every paycheck, and now he had a W-2 in hand and no idea what to do with it. Was he a resident for tax purposes? Did he file the same form as his American colleagues? What about his bank account back in Spain? This guide walks through exactly what Alex needed to know and what most H-1B holders get wrong in their first year.

How to File Taxes as an H-1B Visa Holder: Step 1 – Residency Status
Before you touch any tax form, answer one question: are you a resident alien or nonresident alien for U.S. tax purposes? Your H-1B immigration status does not automatically determine this. Your tax residency is determined separately using the substantial presence test for H-1B holders.
The Substantial Presence Test H-1B Holders Must Pass
You are an H-1B resident alien for tax purposes if you were physically present in the U.S. for:
- At least 31 days during 2025, AND
- At least 183 days over the three-year period using this formula:
- All days present in 2025
- Plus 1/3 of days present in 2024
- Plus 1/6 of days present in 2023
If that total reaches 183 or more, you are a resident alien. You report worldwide income exactly like a U.S. citizen.
Most H-1B holders working full-time meet this test by the end of their first full calendar year. If you arrived in January 2024 and worked through all of 2025, you almost certainly passed the substantial presence test H-1B holders face and are filing as a resident alien for 2025.
If you did not meet the test typically because you arrived late in the year you are a nonresident alien for 2025. Read our full guide: How to File Form 1040-NR as a Nonresident Alien
Step 2: Understand Dual-Status If You Arrived Mid-Year
If 2025 was your first year in the U.S. on an H-1B and you arrived mid-year, you are likely a dual-status alien both a nonresident and a resident in the same tax year. This is one of the most misunderstood parts of H-1B tax filing.
How Dual-Status Works
Nonresident period: From January 1 until the day before you arrived in the U.S taxed only on U.S source income.
Resident period: From your first day of physical presence in the U.S. through December 31 taxed on worldwide income.
Your residency starting date is the first day you were physically present in the United States during 2025.
How to File as a Dual-Status Alien
If you were a resident on December 31, 2025 file Form 1040 as your main return. Write “Dual-Status Return” at the top. Attach Form 1040-NR as a statement showing your nonresident period income.
Key Restrictions for Dual-Status Filers
- Cannot claim the standard deduction must itemize allowable deductions if eligible
- Cannot file a joint return with your spouse (unless you both elect to be treated as residents for the full year)
- Cannot claim the Earned Income Credit, education credits, or credit for elderly or disabled
- New 2025 deductions (tips, overtime, senior) available only to full-year resident aliens dual-status filers may need to prorate eligibility based on their resident period
The First-Year Choice
If you did not meet the substantial presence test in 2025 but want to be treated as a resident for the full year, you can make the first-year choice if:
- You were present in the U.S. for at least 31 consecutive days in 2025
- You were present for at least 75% of the days from that first day through December 31 (up to 5 days of absence count as presence)
This election requires attaching a signed statement to your Form 1040. It allows access to the standard deduction and joint filing status for the full year. Consult a tax professional before making this election it has consequences for future years.
Step 3: Choose the Right Form for H-1B Tax Filing
| Your situation | Form to file |
|---|---|
| Resident alien on December 31, 2025 | Form 1040 |
| Nonresident alien for all of 2025 | Form 1040-NR |
| Dual-status resident on December 31 | Form 1040 + 1040-NR statement |
| Dual-status nonresident on December 31 | Form 1040-NR + 1040 statement |
Most H-1B tax filing situations in year two and beyond involve Form 1040 the standard U.S. individual tax return. Same form as your American colleagues. Same standard deduction ($16,100 for single filers in 2026). Same graduated tax rates. Same filing deadline: April 15, 2026.
Step 4: Know Your H-1B FICA Taxes
This surprises many H-1B holders: you are not exempt from Social Security and Medicare taxes.
H-1B FICA taxes are:
- Social Security: 6.2% of wages up to $184,500 in 2026 (maximum tax $11,439)
- Medicare: 1.45% on all wages (no cap)
Your employer withholds these automatically and reports them on your W-2. Unlike F-1 and J-1 student visa holders who are exempt from FICA for a limited period H-1B holders pay from day one. This is one of the most important distinctions between H-1B taxes and student visa tax rules.
The One Exception Totalization Agreements
If your home country has a totalization agreement with the U.S., you may be exempt from paying Social Security taxes to both countries simultaneously. To claim this exemption, you or your employer must obtain a certificate of coverage from your home country’s social security agency.
Countries with U.S. totalization agreements include the UK, Germany, France, Spain, Italy, Japan, South Korea, and others. Check the full list at SSA.gov/international.
Alex’s situation: Spain has a totalization agreement with the U.S. His employer obtained a certificate of coverage confirming he was covered under the Spanish system. His H-1B FICA taxes were adjusted accordingly. Most H-1B holders never ask about this and overpay as a result.
Step 5: Report All Income Correctly
As an H-1B resident alien filing Form 1040, you report worldwide income not just U.S.-source income.
What this includes:
- U.S. wages from your W-2
- Interest from foreign bank accounts
- Dividends from foreign investments
- Rental income from property in your home country
- Any other income from anywhere in the world
Foreign income is reportable even if it was never brought to the U.S. Many H-1B holders miss this entirely in their first year. Once you are a resident alien, everything is reportable regardless of where it was earned or where it sits.
Step 6: Claim the Deductions Most H-1B Holders Miss
Standard Deduction
H-1B resident aliens filing Form 1040 can claim the full standard deduction $16,100 for single filers in 2026. Many H-1B holders in their first year incorrectly believe they cannot claim this. You can as long as you are filing as a full-year resident alien. Dual-status filers cannot claim the standard deduction and must itemize instead.
Foreign Tax Credit (Form 1116)
If you paid taxes to your home country on income that is also taxable in the U.S., claim a credit for those foreign taxes on Form 1116. This eliminates double taxation on the same income. One of the most valuable and most overlooked credits for H-1B holders with home-country income.
Retirement Contributions
Contributions to a 401(k) through your employer reduce your taxable income dollar for dollar. If your employer offers a 401(k) and you are not contributing, you are paying more tax than necessary.
Dependent Credits
If your H-4 spouse or dependent children qualify, you may be able to claim the Credit for Other Dependents ($500 per qualifying dependent). Verify eligibility based on your specific situation.
New 2025 Deductions One Big Beautiful Bill Act
The no-tax-on-tips, no-tax-on-overtime, enhanced senior deduction, and qualified passenger vehicle loan interest deduction provisions are available to H-1B holders who are full-year resident aliens and meet the eligibility requirements. These deductions are available only to full-year resident aliens. Dual-status filers may need to prorate eligibility based on their resident period. Nonresident aliens are generally ineligible.
What H-1B Holders Commonly Miss
- Not updating W-4 after a salary increase leading to under or over-withholding
- Forgetting to report RSU (restricted stock unit) vesting as ordinary income
- Skipping state tax returns entirely
- Missing pre-tax benefit elections for FSA or HSA that reduce taxable income
- Not claiming the foreign tax credit on home-country income
Step 7: Handle State Taxes
H-1B taxes include state income tax obligations in every state where you live or work even part-year. State deadlines generally mirror the federal April 15, 2026 deadline.
If you worked in multiple states during 2025: common for H-1B holders who transferred locations or worked remotely you may need to file returns in multiple states and allocate income between them.
States with no income tax: Texas, Florida, Washington, Nevada, Wyoming, South Dakota, Alaska. If you live and work in one of these states, no state income tax return is required.
States with aggressive tax rules: California taxes former residents on certain types of income even after they leave. If you lived in California during 2025 and moved out, check whether any income remains subject to California tax.
Alex lived and worked in Texas the entire year. No state return required. He filed only his federal Form 1040.
FBAR and Foreign Account Reporting
If you have a foreign bank account and the combined balance exceeded $10,000 at any point during 2025, you must file an FBAR (FinCEN Form 114) separately from your tax return. This is one of the most expensive mistakes H-1B holders make penalties can reach $16,000+ per missed year.

2026 Key Deadlines for H-1B Tax Filing
| Deadline | What it covers |
|---|---|
| April 15, 2026 | Form 1040 due date for most H-1B filers |
| April 15, 2026 | FBAR due date (auto-extends to October 15) |
| June 15, 2026 | For nonresident aliens abroad rare situation for most U.S.-based H-1B holders |
| October 15, 2026 | Extended deadline if Form 4868 filed by April 15 |
Extension rule: Filing Form 4868 extends your time to file not your time to pay. If you owe taxes, pay by April 15 to avoid penalties and interest.
Alex’s Filing Situation
Alex arrived in Austin in May 2024. By the end of 2025 his first full calendar year he had passed the substantial presence test H-1B holders must meet. He was a resident alien for all of 2025.
He filed Form 1040. He claimed the standard deduction ($16,100). He reported his U.S. wages from his W-2 and the interest from his Spanish bank account. He filed an FBAR because his Spanish account had briefly crossed $10,000.
He used Form 1116 to claim a foreign tax credit for Spanish taxes paid on the bank interest eliminating double taxation on that income. His employer had obtained a certificate of coverage under the U.S.-Spain totalization agreement, reducing his H-1B FICA taxes.
His refund arrived 18 days after e-filing.

Frequently Asked Questions
What is H-1B tax filing is it different from regular US tax filing?
H-1B tax filing follows the same rules as any U.S. resident once you pass the substantial presence test. You file Form 1040 and report worldwide income. The main differences from a regular U.S. citizen filing are: you may have foreign income to report, you may have FBAR obligations, and your first year may require dual-status filing.
What is the substantial presence test for H-1B holders?
The substantial presence test H-1B holders must pass requires 31 days of presence in 2025 plus 183 weighted days over three years (all 2025 days + 1/3 of 2024 days + 1/6 of 2023 days). Most full-time H-1B workers pass this test by the end of their first full calendar year in the U.S.
What is my status as an H-1B resident alien?
Once you pass the substantial presence test, you are classified as an H-1B resident alien for tax purposes. This means you file Form 1040, report worldwide income, can claim the standard deduction, and are subject to the same tax rates as U.S. citizens. Your immigration H-1B status and your tax residency status are determined separately.
What are H-1B FICA taxes?
H-1B FICA taxes are Social Security and Medicare taxes withheld from your wages. In 2026, Social Security is 6.2% on wages up to $184,500 (maximum $11,439). Medicare is 1.45% on all wages with no cap. H-1B holders are not exempt from FICA unlike some student visa holders. If your home country has a totalization agreement with the U.S., you may be able to avoid double Social Security contributions.
Do H-1B holders get a tax refund?
Many do, particularly in their first year when employers withhold at a generic rate. File your return and claim all applicable deductions and credits your refund depends on your specific situation.
Can my H-4 spouse file jointly with me?
Yes, if you are both treated as resident aliens for the full year. If your spouse is a nonresident alien, you can elect to treat them as a resident and file jointly but their worldwide income becomes reportable on your joint return. Read IRS Publication 519 before making this election.
I changed jobs mid-year. Do I get two W-2s?
Yes. You will receive a W-2 from each employer. Report all of them on your Form 1040.
Can I contribute to an IRA on an H-1B?
Yes, if you have earned income. Both traditional and Roth IRAs are available to H-1B holders who meet the income requirements. Traditional IRA contributions may be tax-deductible depending on your income and whether you have a workplace retirement plan.
What happens to my Social Security contributions if I leave the U.S.?
Social Security benefits are available to non-citizens who have earned enough credits (generally 40 credits about 10 years of work). Totalization agreements with some countries allow combining U.S. and home-country credits toward benefit eligibility.
Conclusion
H-1B taxes come down to one determination: did you pass the substantial presence test? If yes, you file Form 1040 as an H-1B resident alien, claim the standard deduction, and report worldwide income. If you arrived mid-year, dual-status rules apply and the filing is more complex.
The two mistakes that cost H-1B holders the most money: forgetting to report foreign income and missing the FBAR. Both are easily avoided with the right checklist.
