Form W-9 (sp): Spanish Request for Taxpayer Identification Number and Certification
Form W-9 (sp) is the Spanish version of Form W-9, Request for Taxpayer Identification Number and Certification. The PDF is in Spanish under the title "Solicitud y Certificación del Número de Identificación del Contribuyente" and is dated March 2024 ("Rev. marzo de 2024", Rev. 3-2024). The six-page PDF holds the form and its general and specific instructions, all in Spanish.
The form explains that a person or business that has to file an information return with the IRS (the requester) gives you this form to get your correct taxpayer identification number (TIN): an SSN, ITIN, ATIN or EIN. The examples it lists include Forms 1099-INT, 1099-DIV, 1099-MISC, 1099-NEC, 1099-B, 1099-S, 1099-K, 1098, 1098-E, 1098-T, 1099-C and 1099-A. It is only for U.S. persons, including resident aliens.
The top of the form says to give it to the requester and not to send it to the IRS. In a few places the Spanish form asks for English words, such as "NEW" and "Applied For". The English edition, Form W-9, has its own page. You can fill out this Spanish PDF free in your browser on this page and download it without an account.

Line 4: exemptions
Spaces for an exempt payee code and a FATCA exemption code. The form says these codes apply only to certain entities, not individuals.

Your address, your city, state and ZIP code, optional account numbers, and an optional box for the requester's name and address.
Part I: TIN
Two boxes, one for a Social Security number and one for an employer identification number. The TIN has to match the name on line 1.

Four statements made under penalty of perjury, then the signature of the U.S. person and the date.
How to fill out Form W-9 (sp)
- 1
Line 1
Enter the name that matches your tax return and do not leave it blank. If your last name changed without telling the SSA, the form says to enter your first name, the last name on your Social Security card and your new last name.
- 2
Line 3a
Check only one box. An LLC that is not disregarded checks the LLC box and enters C, S or P. A disregarded entity checks the box for its owner's classification.
- 3
Line 4
The form says individuals, including sole proprietors, generally are not exempt from backup withholding. If you give the form only because of an account held in the United States, the form says the FATCA code space can stay blank.
- 4
Lines 5 and 6
Enter your address and your city, state and ZIP code. If the address differs from the one the requester has on file, write "NEW" at the top, as the form says.
- 5
Part I
Enter the SSN or EIN that matches line 1. A resident alien without an SSN enters an ITIN in the SSN boxes. With no TIN yet, the form says to apply for one and write "Applied For" in the TIN space.
- 6
Part II
Sign and date. Cross out item 2 if the IRS has told you that you are currently subject to backup withholding for not reporting all interest and dividends.

Where it goes, withholding and penalties
Where it goes
Give the completed form to the requester. The top of the form says not to send it to the IRS.
Backup withholding
The form says that under certain conditions payers withhold 24% of certain payments and pay it to the IRS, for example when no TIN is given or the IRS reports the TIN as incorrect.
TIN applied for
For interest, dividend and certain readily tradable instrument payments, the form says you generally have 60 days to get a TIN and give it to the requester. Other payments face backup withholding until you do.
Penalties
The form lists a $50 penalty for each failure to give a correct TIN, unless due to reasonable cause, and a $500 penalty for a false statement with no reasonable basis that results in no backup withholding.
Keeping it current
The form says to give a new Form W-9 if the name or TIN on the account changes, and to update anyone you told you were an exempt payee if that is no longer true.
