Living in the United States as a nonresident alien comes with a number of tax responsibilities that are often unfamiliar to international visitors. Whether you’re an international student, researcher, or dependent, the U.S. tax system requires you to report certain types of income. A key part of this reporting process involves obtaining an Individual Taxpayer Identification Number (ITIN) if you do not qualify for a Social Security Number (SSN).<\/span><\/p>\n

Many nonresidents enter the U.S. under visa categories that allow limited work or no employment at all. In such cases, an SSN may not be issued, yet the individual may still need to file a tax return or claim a refund. That\u2019s where the ITIN comes in. The ITIN is used by the Internal Revenue Service to process tax returns and other filings for people who are ineligible for an SSN but still have tax obligations. This series covers the fundamentals of what an ITIN is, who needs it, and why it matters for nonresident aliens.<\/span><\/p>\n

What Is an ITIN?<\/b><\/p>\n

An ITIN, or Individual Taxpayer Identification Number, is a tax processing number issued by the Internal Revenue Service. It is a nine-digit number that begins with the number 9 and is used solely for federal tax purposes. The ITIN is issued to individuals who are required to have a U.S. taxpayer identification number but are not eligible to obtain a Social Security Number.<\/span><\/p>\n

The purpose of the ITIN is to enable individuals who are not authorized to work in the U.S. but have taxable income or other filing requirements to comply with U.S. tax law. This includes nonresident aliens, their spouses, and dependents.<\/span><\/p>\n

ITINs do not authorize an individual to work in the United States, nor do they provide eligibility for Social Security benefits or alter immigration status. They are strictly for the purpose of fulfilling tax reporting and filing obligations.<\/span><\/p>\n

Why Nonresident Aliens Need an ITIN<\/b><\/p>\n

There are several common reasons why a nonresident alien may need to apply for an ITIN. The following categories outline the most typical circumstances under which an ITIN is required.<\/span><\/p>\n

Receiving Taxable Scholarships, Fellowships, or Grants<\/b><\/p>\n

International students and scholars often receive financial aid in the form of scholarships, fellowships, or grants. When these funds cover more than just qualified education expenses such as tuition and required fees\u2014like when they are used for housing, meals, or travel\u2014they may be considered taxable income by the IRS.<\/span><\/p>\n

To report this income on a federal tax return, students who are not eligible for an SSN must apply for an ITIN. Without this number, the IRS cannot process the tax return or any associated refund.<\/span><\/p>\n

Claiming Benefits Under a Tax Treaty<\/b><\/p>\n

The United States has income tax treaties with numerous countries. These treaties often reduce or eliminate tax on specific types of income, including scholarships, compensation for services, or other earnings. To claim a treaty exemption, a taxpayer must include an ITIN or SSN on the applicable forms and the federal return. For individuals who do not qualify for an SSN, applying for an ITIN is necessary in order to benefit from tax treaty provisions.<\/span><\/p>\n

Filing a U.S. Federal Tax Return Without an SSN<\/b><\/p>\n

Many nonresident aliens have U.S. tax filing obligations but do not qualify for an SSN due to their visa status or ineligibility to work. These individuals must use an ITIN to fulfill their filing requirements. Common examples include students on F-1 or J-1 visas who receive income from non-employment sources, or scholars and researchers receiving grant-based support.<\/span><\/p>\n

Filing without the appropriate identification number can result in the return being rejected or delayed, and failure to file can result in penalties or loss of eligibility for tax treaty benefits.<\/span><\/p>\n

Filing a Return to Claim a Refund<\/b><\/p>\n

Some taxpayers may not owe any tax, but they may be eligible for a refund of taxes that were withheld from their income. For example, a student may have had taxes withheld from a scholarship payment or part-time employment but ultimately owes less or nothing based on treaty eligibility or income thresholds. In such cases, an ITIN is still required to submit the tax return and request a refund.<\/span><\/p>\n

Being Claimed as a Dependent or Spouse on a U.S. Tax Return<\/b><\/p>\n

If a nonresident alien is being claimed as a spouse or dependent on another individual\u2019s U.S. tax return, and does not qualify for an SSN, they will need to apply for an ITIN. This often applies to families in which only one parent is working and filing taxes while the spouse and children are on dependent visas.<\/span><\/p>\n

U.S. Resident Aliens for Tax Purposes Without an SSN<\/b><\/p>\n

In certain cases, individuals in the U.S. may be considered resident aliens for tax purposes based on the substantial presence test, even if their visa status remains temporary. If these individuals do not qualify for an SSN, they must obtain an ITIN to file their tax return as required by the IRS.<\/span><\/p>\n

Who Should Not Apply for an ITIN<\/b><\/p>\n

Although many nonresidents need an ITIN, there are cases where it is not appropriate to apply:<\/span><\/p>\n
