I don’t usually file taxes, what will I need to submit to sign up for the Child Tax Credit?

Signing up for the Child Tax Credit is simple: you only need a working email address or phone number and the social security numbers of any children you want to claim.

Children claimed for the Child Tax Credit must have a valid Social security number (SSN), however the tax filer (a parent, grandparent, or guardian) can have either a SSN or an Individual Taxpayer Identification Number (ITIN).
