When an immigrant arrives in the United States, one of the first questions is how to work and file taxes without having a Social Security number (SSN). This is where the ITIN, Individual Taxpayer Identification Number, comes in. However, it is common to confuse it with a work permit or an SSN, which can create problems.
This blog explains the difference between an ITIN, an SSN, and work permits, and what it really means to work with an ITIN.

What is an ITIN?
The ITIN is an identification number issued by the IRS, the Internal Revenue Service. It is used only for tax purposes, meaning to file taxes. It does not authorize legal work in the United States. It does not provide Social Security benefits or change immigration status. In short, the ITIN is a tool to comply with tax responsibilities, but it is not a work document.
What is an SSN?
An SSN is a Social Security number that the U.S. government primarily grants to U.S. citizens, permanent residents, and some people with immigration status authorized to work. The SSN is not only used to file taxes; it also allows legal employment, access to Social Security and Medicare benefits, opening bank accounts, applying for credit, and more.

What is a work permit (EAD)?
The Employment Authorization Document, known as a work permit, is a card issued by USCIS that grants certain immigrants temporary authorization to work legally in the country. With an EAD, you can obtain employment with full labor rights, request an SSN valid for work, and access labor protections under the law.
So, can you work with an ITIN?
The ITIN does not give the right to work legally in the United States. Many people use it to pay taxes even without work authorization. Some companies accept it for informal hiring, but that does not mean the work is legal. To be protected by labor and immigration law, it is necessary to have a valid work permit or an SSN authorized for work.

Having an ITIN is useful and can be positive for your future because it shows that you comply with tax responsibilities. However, it should not be confused with a work permit or an SSN. ITIN: only for taxes. SSN: for work and access to benefits. Work permit (EAD): gives legal authorization to work in the United States. Complying with tax laws is important, but if you want to work legally and safely, it is essential to know the difference and, when possible, apply for the appropriate authorization.
