Individual Taxpayer Identification Number (ITIN)

An ITIN is an identification number issued by the IRS to individuals who are not eligible to obtain a Social Security Number (SSN). This number serves as an identification number to file taxes and get a tax refund from income withheld by the IRS, but can also be used to open bank accounts and apply for loans.

An ITIN is not a substitute for an SSN and cannot be used to obtain a driver's license, work authorization, or Social Security benefits. You may not have both an ITIN and an SSN.

More information and locations of IRS Taxpayer Assistance Centers in Illinois that can authenticate copies of your Passport/identification documents can be found here and a list of central Illinois IRS Acceptance Agents who can assist you in filing your tax return and ITIN application(s) for a fee is here (pdf).

To apply for an ITIN, you need:

• Completed Form W-7
• Original tax return(s)
• Original identification documents or certified copies from the issuing agency (for example, copies of your passport must be certified by your consulate or embassy), at selected IRS Taxpayer Assistance Centers, or through an IRS Acceptance Agent (pdf).
• Original passport
  OR
  Two unexpired documents supporting the identification information provided in the Form W-7, including at least one photo identification and an identification from your country of origin.
• All individuals listed as dependents on the tax return, including spouse (husband/wife), all children, and any others, must go with the taxpayer in person, if going to a Taxpayer Assistance Center or an Acceptance Agent.
