Your child will definitely be eligible for the child tax credit and should be eligible for both rounds of the stimulus credit if and only if you file an on-time tax return listing her as your dependent with a Social Security number. An on-time tax return means one that is filed before April 15, or, that is filed before October 15 if you have first obtained the automatic extension. To get the tax credits, you need to delay filing your tax return until you have your child’s new Social Security number, even if you must miss the first deadline and get an extension. Don’t file using the ITIN, and don’t file without your child planning to amend later, but do make sure to file your extension request before April 15 if you don’t have the SSN by then.
