No, you cannot legally work in the United States with an ITIN alone. An Individual Taxpayer Identification Number is a nine-digit number the IRS issues strictly for federal tax purposes, and the agency states directly that it “creates no inference concerning your immigration status or your right to work in the United States.”1Internal Revenue Service. Topic No. 857, Individual Taxpayer Identification Number (ITIN) Work authorization is a separate matter governed by immigration law, and it comes from a visa, lawful status, or an Employment Authorization Document from U.S. Citizenship and Immigration Services.
What an ITIN Is Actually For
The IRS issues ITINs to people who have a U.S. federal tax filing obligation but don’t qualify for a Social Security Number. That includes certain foreign nationals, nonresident aliens with U.S.-source income, and dependents or spouses of U.S. citizens or residents. The IRS issues ITINs regardless of immigration status because both resident and nonresident aliens can owe tax under the Internal Revenue Code.2Internal Revenue Service. Individual Taxpayer Identification Number (ITIN)
An ITIN lets you file returns, report income, and pay what you owe. That is the entire function. According to the IRS, an ITIN does not qualify you for Social Security benefits, make you eligible for the Earned Income Tax Credit, provide or change your immigration status, authorize you to work, or serve as identification outside the federal tax system.2Internal Revenue Service. Individual Taxpayer Identification Number (ITIN) You also cannot hold both an ITIN and a Social Security Number at once.
Why an ITIN Fails the Hiring Process
Every employer in the United States must complete Form I-9 for each new hire, and the employee has to present documents proving identity and work authorization within three business days of starting. The accepted documents are grouped into three lists: a single List A document that proves both (like a U.S. passport or Permanent Resident Card), a List B identity document, or a List C work-authorization document such as an unrestricted Social Security card.3U.S. Citizenship and Immigration Services. Form I-9 Acceptable Documents An ITIN letter or card appears on none of those lists.4U.S. Citizenship and Immigration Services. 13.0 Acceptable Documents for Verifying Employment Authorization and Identity
Employers who run new hires through E-Verify hit the same wall. The system’s own guidance states that “ITINs and the cards on which they are printed do not provide evidence of employment authorization and are not acceptable for Form I-9 or E-Verify.”5E-Verify. My Employee Entered a Set of Numbers in the Social Security Number Field on Form I-9 Entering an ITIN in the Social Security Number field on Form I-9 will trigger a Tentative Nonconfirmation, and there is no way to resolve it because the underlying issue isn’t a clerical mismatch. The person lacks work authorization.6E-Verify. Tentative Nonconfirmations (Mismatches)
The 1099 and Independent Contractor Myth
A common misunderstanding is that ITIN holders can bypass all of this by working as independent contractors. It’s true that businesses don’t complete Form I-9 for contractors, and it’s also true that an ITIN can appear as the payee’s taxpayer identification number on Form 1099-NEC, the form used to report payments to non-employees. The IRS accepts ITINs there because the form serves a tax-reporting function.7Internal Revenue Service. General Instructions for Certain Information Returns
None of that makes the work legal. Federal law prohibits individuals or businesses from contracting with an independent contractor when they know the contractor is not authorized to work in the U.S.8U.S. Citizenship and Immigration Services. Exceptions The I-9 exemption for contractors is a paperwork rule, not a grant of work authorization. Receiving a 1099 does not mean the underlying work was lawful from an immigration standpoint.
The Immigration Consequences of Working Anyway
Working without authorization can follow you for years. Under USCIS policy, if you accepted or continued unauthorized employment at any point before filing an application to adjust status, you may be ineligible to become a lawful permanent resident. The rule reaches your entire U.S. employment history, not just recent work.9U.S. Citizenship and Immigration Services. Chapter 6 – Unauthorized Employment
Leaving the country and returning does not reset the clock. USCIS officers review an applicant’s full employment record across all entries into the United States, with no time limit on how far back they look.9U.S. Citizenship and Immigration Services. Chapter 6 – Unauthorized Employment Some categories are exempt from this bar, including immediate relatives of U.S. citizens and VAWA applicants. For most people, though, a history of unauthorized work creates a serious obstacle to future legal status.
You Still Owe Taxes on Whatever You Earn
Immigration law and tax law operate on separate tracks. The IRS expects you to report all income and pay taxes on it regardless of whether you were authorized to earn it. Filing keeps you in good standing with the IRS, and if you later gain legal status, a clean tax record can help in immigration proceedings while a history of non-filing works against you.
ITIN holders with self-employment income of $400 or more must file Schedule SE and pay self-employment tax covering Social Security and Medicare. The IRS specifically states that either an SSN or an ITIN can be used to pay self-employment tax.10Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Resident aliens without an SSN can enter their ITIN on Form W-9 when a business asks for a taxpayer identification number.11Internal Revenue Service. Form W-9 (Rev. March 2024) – Request for Taxpayer Identification Number and Certification
Filing with an ITIN comes with real limits on credits, though. You cannot claim the Earned Income Tax Credit with an ITIN.1Internal Revenue Service. Topic No. 857, Individual Taxpayer Identification Number (ITIN) Self-employment taxes paid under an ITIN also don’t earn Social Security credits toward retirement or disability benefits while you hold only the ITIN. If you later receive a Social Security Number, earnings previously reported under your ITIN may be credited to your Social Security record once your tax accounts are combined.
How People Actually Get Work Authorization
Legal work authorization runs through immigration law, not the tax system. The main categories of people who can work in the United States are:
- U.S. citizens, whether born or naturalized, who have an inherent right to work.
- Lawful permanent residents, who can work for any employer without restriction.12USAGov. Work Permit (EAD)
- Holders of work visas such as H-1B for specialty occupations, which authorize employment for a specific employer without a separate work permit.13U.S. Citizenship and Immigration Services. 7.5 H-1B Specialty Occupations
- Holders of an Employment Authorization Document (EAD), which provides temporary work authorization to people in various categories including asylum seekers, certain students, and applicants for permanent residency.14U.S. Citizenship and Immigration Services. Employment Authorization Document
If you currently hold only an ITIN and want to work legally, the practical step is consulting an immigration attorney about whether any pathway applies to your situation. The ITIN won’t get you there. What it does is keep you compliant with the IRS while your immigration situation is being worked out.
What Happens When You Get a Social Security Number
If you gain work authorization and receive a Social Security Number, you must stop using your ITIN and use the SSN for all tax purposes going forward. The IRS does not allow you to keep both.15Internal Revenue Service. Additional ITIN Information
You also need to tell the IRS so your prior tax history gets merged under the new SSN. If you skip this step, you may not get credit for wages and taxes previously reported under your ITIN, which can reduce future refunds and Social Security earnings credit. You can visit a local IRS office in person or send a letter to the IRS at Austin, TX 73301-0057 explaining that you’ve received an SSN and want your records combined. Include your full name, mailing address, ITIN, a copy of your Social Security card, and, if you still have it, your CP 565 notice (the ITIN assignment letter).15Internal Revenue Service. Additional ITIN Information Once processed, the IRS voids the ITIN and links your prior tax history to the SSN.
