I got a question from someone who is in the US but from abroad. He has a Social security Number, but wasn't aware one was needed for his children. His tax returns were rejected for that reason for several years, and he had to amend them.
Now his children have SS numbers. Can he file amended returns for past years now that they have SS numbers? The IRS says you can do that for a child born in the US who hasn't received their number yet. But can you do that for foreign children?
Thanks for any insights you may have.
