Can I file a tax return if I don't have a Social Security number (SSN), ITIN, or ATIN for my child?

If you file a paper return, the IRS may reduce or disallow any tax benefits (such as the Earned Income Credit, or Child Tax Credit) based on the dependent. To claim a child as a dependent, you need to have a Social Security Number, ITIN, or ATIN for that child. If you don't, the IRS will reject your e-filed return. If you file a paper return, the IRS might reduce or deny any tax benefits (like the Earned Income Credit, or Child Tax Credit) based on the dependent.

If you need a Social Security number for your dependent, visit ssa.gov to learn how to get one.

If you need an ITIN for your dependent, go to irs.gov to download a Form W-7 to file with the IRS to obtain an ITIN. If you're filing your federal return before the due date, you can apply for an ITIN for your dependent while filing your return.

If you need an ATIN as a temporary identification number for a child you are in the process of adopting and you're not yet able to get a Social Security number, go to irs.gov to download Form W-7A to file with the IRS to obtain an ATIN.

If the filing date is approaching and you still haven't received a Social Security Number, ITIN, or ATIN, you may want to consider filing an extension with Form 4868.
