What Is Form W-7(SP) and What Is an ITIN?
Form W-7(SP) is the Spanish-language application used to request or renew an Individual Taxpayer Identification Number (ITIN). An ITIN is a nine-digit number issued by the IRS exclusively for federal tax purposes. It allows individuals who cannot obtain an SSN to:
- File U.S. tax returns (Form 1040, 1040-NR, etc.)
- Claim refunds or tax treaty benefits
- Report income subject to withholding
- Include dependents or spouses on joint returns (when eligible)
Important limitations:
- An ITIN does not authorize work in the U.S., provide Social Security benefits, or change immigration status.
- ITINs issued after 2017 cannot be used to claim the Earned Income Tax Credit (EITC) or, for tax years 2018–2025, the Child Tax Credit (CTC) or Additional Child Tax Credit (ACTC) for qualifying children.
The Spanish version (W-7(SP)) is identical in content to the English Form W-7 but is fully translated for easier use by Spanish speakers. If you want future IRS correspondence in Spanish, submit the Spanish form.
Who Needs Form W-7(SP)?
You should file Form W-7(SP) if you are not a U.S. citizen or permanent resident and:
- Are a nonresident alien required to file a U.S. tax return
- Are a resident alien (based on substantial presence) filing a return
- Need to claim a tax treaty benefit
- Are a dependent or spouse on someone else’s U.S. return (with restrictions after 2017)
- Are a student, professor, or researcher on a visa
- Have U.S.-source income subject to reporting or withholding (e.g., gambling winnings, scholarships, real estate sales)
- Need to renew an expiring ITIN
Do NOT file if you already have (or qualify for) an SSN — apply for an SSN instead using Form SS-5(SP).
