The ITIN was created for tax purposes. The ITIN was created by the IRS in July 1996 to allow foreign nationals and other individuals who are not eligible for a SSN to comply with U.S. tax laws. ITINs are not SSNs. The ITIN is a nine-digit number that always begins with the number 9 and has a range of numbers from 50 to 65, 70 to 88, 90 to 92, and 94 to 99 for the fourth and fifth digits. The ITIN is formatted like a SSN: 9XX-7X-XXXX. Many immigrants have ITINs. People who do not have a lawful status in the United States may obtain an ITIN. But other people who are lawfully present in the country and must pay taxes, but who may not be eligible for a SSN, may also obtain an ITIN, including:
A non-resident foreign national who is engaged in trade or business in the United States, or who has U.S. income, but who lives in another country.
A non-resident foreign national student, professor, or researcher filing a U.S. tax return. A dependent or spouse of a U.S. citizen or lawful permanent resident.
A dependent or spouse of a foreign national on a temporary visa.
ITINs do NOT provide legal status or work authorization. An ITIN does not provide legal immigration status and cannot be used to prove legal presence in the United States. An ITIN does not provide work authorization and cannot be used to prove work authorization on an I-9 form. ITIN holders pay taxes. ITINs let more people pay into the system, which builds the tax base.
According to the IRS, in 2015, “4.4 million ITIN filers paid over $5.5 billion in payroll and Medicare taxes and $23.6 billion in total taxes.” ITIN holders are not eligible for all of the tax benefits and public benefits that U.S. citizens and other taxpayers can receive. For example, an ITIN holder is not eligible for Social Security benefits or the Earned Income Tax Credit (EITC). However, if that person becomes eligible for Social Security in the future (for example, by becoming a lawful permanent resident), the earnings reported with an ITIN may be counted toward the amount he or she is eligible to receive.
Some ITIN holders are eligible for the Child Tax Credit (CTC). According to federal legislation passed in March 2021, the CTC may be worth up to $3,600 for each child under 6 and up to $3,000 for each child age 6 to 17, depending upon the applicant’s income. Because ITIN holders are eligible for the CTC, the IRS estimated in 2014 that up to 4 million U.S.-citizen children of ITIN holders benefit from the tax credit. If a child does not have a SSN, he or she is not eligible for the tax credit.
