How Foreign Nationals on Work Visas Should File Their U.S. Taxes?

Foreign national US tax filing can be confusing for H-1B, L-1, and O-1 visa holders. Knowing which income is taxable, which forms to file, and how your residency status affects your taxes is essential. Your status determines taxable income and eligible deductions.

Understanding these rules helps you stay compliant, avoid penalties, and make the filing process much simpler. Particular deductions and credits can help reduce your tax bill, but only if you know how to apply them. 

If you do not have a Social Security number, you may need an ITIN to file your taxes. This guide explains everything step by step in a simple way, so filing your U.S. taxes becomes easier and more manageable.

Who Needs to File a U.S. Tax Return?

If you earn income in the U.S., you generally must file a tax return. This includes wages, salaries, and sometimes other income like interest or rental income.

Whether you are on an H-1B, L-1, or O-1 visa, you are considered a foreign national US tax filing candidate if you meet the income thresholds.

• H-1B visa holders: Usually employees in specialty occupations. Required to report income from their U.S. job and must file an H1B tax return.
• L-1 visa holders: Intra-company transferees. Must report U.S. earnings and may have special treaty benefits.
• O-1 visa holders: Individuals with extraordinary ability. Must report any U.S. wages or self-employment income.

Understanding Resident vs. Nonresident Alien Status

Your tax liability in the United States is based on whether you are a resident or a nonresident alien. This is because it will determine the income subject to taxation and which forms need to be filed. The IRS classifies people into:

• Resident Alien - taxed as a US resident on global income. Meets either the Green Card test or the substantial presence test.
• Nonresident Alien - Nonresident alien tax is applicable only on US source income. Often applies to new H1B, L1, and O1 Visa holders.
• Substantial Presence Test - You are a resident alien if you are physically present in the U.S. for at least 31 days in the current year and 183 days over three years using a weighted formula. This test is critical for H-1B, L-1, and O-1 visa holders as it directly determines their tax filing obligations..

Forms to Use

Important forms for foreign nationals/non-resident aliens residing and working in the U.S. are:

• Form 1040NR – This is the form filled with the IRS for non-resident aliens to file their U.S. income taxes.
• The work visa taxes USA filing requirements for the form are decided by the Substantial Presence Test.

Note: Accurate form selection is crucial because mistakes can lead to delays or audits.

What Is a Dual-Status Tax Year and How Does It Affect You?

A dual-status tax year happens when your residency status changes during the year. Part of your income is taxed as a nonresident, and the rest as a resident, so it’s important to report each portion correctly. This situation is called a dual-status tax year.

• You report income as a nonresident for the part of the year before becoming a resident.
• After meeting the resident criteria, you report worldwide income for the rest of the year.
• Dual-status filings are more complex, so careful tracking of dates and income is essential.

Tax Deductions and Credits for Foreign Nationals

Knowing the type of deduction or credit you are eligible for can help you save money or prevent you from paying too much in taxes.

• Standard Deduction: This type of deduction is for resident aliens, not non-resident aliens.
• Itemized Deductions: Some non-resident aliens are eligible for state taxes, charitable donations, or business expenses.
• Tax Credits: Foreign nationals may be eligible for education credits, child tax credits (residents only), and foreign tax credits if paying taxes in another country.

Using deductions and credits wisely can significantly lower your tax liability.

Applying for an ITIN If You Don’t Have a Social Security Number

If you’re a foreign national without a Social Security Number, you’ll need an Individual Taxpayer Identification Number (ITIN) to file your U.S. taxes. It allows the IRS to process your return and track your tax obligations.

• Apply using Form W-7 with your tax return.
• Provide original documents or certified copies to prove identity and foreign status.
• ITINs are used only for tax filing and do not confer work authorization.
