Tax Forms Foreign Workers Need in the U.S.

A first U.S. tax season can feel confusing because your mailbox may contain forms with similar-looking numbers but very different purposes. The tax forms foreign workers receive are not determined by a visa label alone. They depend on how you were paid, whether you are a U.S. tax resident, and whether you used a tax treaty or had income beyond your regular job.

The practical goal is simple: collect every form that reports income or withholding, determine your tax residency before choosing a return, and do not assume the form your coworker files is the right one for you. An H-1B employee in year three, an F-1 student in year one, and a new green-card holder can all work for the same company while having different tax filing rules.

Start with tax residency, not your visa

For federal income tax, the IRS generally treats a person as either a resident alien or a nonresident alien. This is a tax classification, not an immigration classification. It controls which return you file, what income you report, and whether certain deductions, credits, or treaty benefits may be available.

You may be a resident alien if you meet the green card test or the substantial presence test. The substantial presence test counts days physically present in the United States over a three-year period using a weighted formula. Many H-1B, L-1, TN, O-1, and E visa holders become resident aliens after enough time in the country.

F-1 students and J-1 exchange visitors often have a different starting point. Certain students, teachers, trainees, and researchers can exclude days from the substantial presence calculation for a limited period as “exempt individuals.” Exempt here means exempt from counting days for this test, not exempt from tax. A student with U.S. wages can still owe federal and state income tax.

Your status can change during the year. For example, an F-1 student who has used up the applicable exempt-individual period may become a resident alien after meeting substantial presence. In some transition years, you may have dual-status tax residency. That is one reason software designed only for ordinary resident returns can produce the wrong result for a foreign worker.

The tax forms foreign workers most often receive

Form W-2: wages from an employer

A W-2 reports wages paid by an employer and the taxes withheld from your paycheck. Most employees, including H-1B workers, OPT employees, L-1 workers, and green-card holders, receive it by the end of January for the prior tax year.

Check your W-2 before filing. Confirm that your name and Social Security number are correct, compare the wage amount with your final paystub, and look at federal and state withholding separately. A W-2 does not tell you whether you are a resident alien or nonresident alien. It simply reports payroll information.

If you changed employers, you should receive a W-2 from each employer. If you moved states while working remotely or relocated for a new role, you may also have multiple state wage entries. That can mean more than one state return, even if you lived in the United States for only part of the year.

Form 1042-S: treaty income and other payments to nonresidents

Form 1042-S often surprises international students and workers because it may arrive alongside a W-2. It reports certain U.S.-source income paid to foreign persons, including scholarship amounts, tax treaty-exempt wages, fellowship payments, royalties, and some investment income.

A common example is an F-1 or J-1 employee who claimed an income tax treaty benefit through payroll. The employer may report regular taxable wages on a W-2 and treaty-exempt wages on a 1042-S. Both forms can matter on your return. Do not ignore a 1042-S just because the income was exempt from withholding or appears separate from your regular wages.

Treaty eligibility is specific. It can depend on your country of tax residence, visa category, purpose of stay, time in the United States, and the type of income. A treaty benefit that applied while you were a nonresident may no longer apply after you become a resident alien. It is worth reviewing this each year rather than carrying forward an old payroll election.

Form 1099: nonemployee, bank, and investment income

A 1099 usually reports income that was not paid through regular payroll. You may receive a 1099-INT for bank interest, a 1099-DIV for dividends, a 1099-B for investment sales, or a 1099-NEC for independent contractor income.

This is where immigration status and work authorization need to be kept separate from tax reporting. Receiving a 1099-NEC means the payer treated you as an independent contractor for tax purposes. It does not confirm that the work was allowed under your visa status. Before accepting freelance work, confirm that your immigration category permits it. For many visa holders, unauthorized self-employment can create immigration consequences even if the income is accurately reported on a tax return.

For nonresident aliens, some common 1099 reporting rules work differently. For instance, bank deposit interest may not be taxable in the same way it is for resident taxpayers. The form you receive is useful, but it is not the final answer on taxability.

Form 1098-T and scholarship records

Students may receive Form 1098-T from their school showing tuition and scholarship information. It can help document education-related amounts, but international students should be cautious about claiming education credits. Many credits require the taxpayer to be a resident alien for tax purposes, or to make an election in limited circumstances. Being enrolled at a U.S. university does not automatically make every education credit available.

Keep scholarship letters, billing statements, and records showing how scholarship funds were used. Amounts used for qualified tuition and required fees can be treated differently from amounts used for housing, meals, travel, or other living costs.

Forms you may need to file, even without tax due

Form 1040 or Form 1040-NR

Resident aliens generally file Form 1040, the same main federal return used by U.S. citizens. They normally report worldwide income, which can include foreign interest, foreign investment income, or income earned before moving to the United States if it falls within their resident period.

Nonresident aliens generally file Form 1040-NR. This return has different rules for deductions, dependents, filing status, and credits. In many cases, a nonresident cannot use the standard deduction. One significant exception applies to certain students and business apprentices from India under the U.S.-India tax treaty.

Do not choose Form 1040 simply because it is more familiar or because a friend used it. Filing the wrong resident status can affect your tax bill and can create inconsistencies if you later need to explain your U.S. tax history.

Form 8843 for exempt individuals

Form 8843 is especially relevant for F-1, J-1, M-1, and Q visa holders who are treated as exempt individuals for the substantial presence test. It explains why days in the United States should not be counted for that test.

You may need to file Form 8843 even if you had no income and do not otherwise need to file a federal return. If you must file Form 1040-NR, Form 8843 is generally attached to that return. If you are not filing a return, its due date is generally June 15. A spouse or child with the relevant status may have a separate filing requirement as well.

Form 8233 and Form W-8BEN

Form 8233 is generally given to an employer or payer, not filed as your annual tax return. It may allow an eligible nonresident alien to claim a tax treaty exemption from withholding on certain compensation, scholarships, or fellowship income.

Form W-8BEN is also usually provided to a bank, broker, or other financial institution. It certifies foreign status for certain withholding and reporting purposes. It is not a substitute for a tax return, and it should not be used by someone who is correctly treated as a U.S. tax resident for that institution’s tax documentation.

Do not overlook payroll and state tax documents

Your federal return is only part of the picture. States have their own residency rules, filing thresholds, and forms. A person can be a nonresident alien for federal tax purposes yet be treated as a state resident under the state’s rules. California, New York, Massachusetts, and other states with large international workforces often require close attention when you move, work remotely, or maintain a home in more than one state.

Also review your payroll withholding. Nonresident F-1 and J-1 employees who remain exempt individuals are often exempt from Social Security and Medicare taxes on authorized employment. If those taxes were withheld in error, the first step is usually to ask the employer for a correction and refund. That exemption does not generally apply once you become a resident alien for tax purposes, and it does not apply to every type of work.

A practical filing checklist

Before you prepare a return, gather your W-2s, 1042-S forms, 1099s, final paystubs, passport travel history, I-94 records, prior-year returns, and any tax treaty paperwork. Your travel history matters because a few days outside the country can affect the substantial presence calculation.

Then identify your federal tax residency for the full year, not just on December 31. Review whether you changed visa category, employer, school, state, marital status, or work arrangement. These changes often matter more than a small difference in income.

Finally, keep copies of the forms and your filed returns. U.S. tax records can be useful later when applying for a mortgage, documenting income, correcting Social Security records, or preparing for a status change. A careful filing is more than a yearly chore. It is part of building a financial record that supports the life you are creating in the United States.
