ITIN (Individual Taxpayer Identification Number)
An ITIN is a 9-digit IRS-issued tax identification number for individuals who are required to have a U.S. taxpayer ID but don't qualify for a Social Security Number.
What you actually need to know
ITINs were created so that non-citizens (and others without SSN eligibility) could still file U.S. tax returns and meet tax reporting requirements. With an ITIN you can:
- File a federal tax return
- Open most U.S. bank accounts (some banks require additional ID; many accept ITIN alone)
- Be listed as the responsible party on an LLC and apply for an EIN
- Apply for MC authority (the FMCSA does not require an SSN)
- Build U.S. credit (with caveats — see related guide)
ITINs always start with the digit 9 and have a 7 or 8 in the fourth position. They look like 9XX-7X-XXXX or 9XX-8X-XXXX.
You apply for an ITIN with IRS Form W-7 plus a federal tax return and certified ID documentation. Processing takes 7–11 weeks.
Common mistakes / confusions
- ITIN is not work authorization. It doesn't give you the right to work in the U.S. It's purely a tax ID.
- An ITIN does not enroll you in Social Security or give you SS retirement benefits.
- ITINs can expire if not used on a tax return for 3+ consecutive years. Renew before you need it.
