Valid Social Security Number
To claim the EITC, you (and your spouse, if filing a joint return) must have a valid SSN issued by the Social Security Administration (SSA). Any qualifying child listed on Schedule EIC must also have a valid SSN.
Not valid for employment: If your social security card (or your spouse’s, if filing a joint return) says “Not valid for employment” and your SSN was issued so that you (or your spouse) could get a federally funded benefit, you cannot get the EITC. An example of a federally funded benefit is Medicaid.
If you have a card with the legend “Not valid for employment” and your immigration status has changed so that you are now a U.S. citizen or permanent resident, ask the SSA for a new social security card without the legend. If you get the new card after you have already filed your return and you meet all the EITC requirements, you can file an amended return on Form 1040X, Amended U. S. Individual Income Tax Return, to claim the EITC.
U.S. citizen : If you were a U.S. citizen when you received your SSN, you have a valid SSN.
Valid for work only with INS or DHS authorization : If your social security card reads “Valid for work only with INS authorization” or “Valid for work only with DHS authorization,” you have a valid SSN.
Other taxpayer identification number : You cannot get the EITC if, instead of an SSN, you (or your spouse, if filing a joint return) have an individual taxpayer identification number (ITIN). ITINs are issued by the Internal Revenue Service to noncitizens who cannot get an SSN.
