I inadvertently claimed my son as a dependent. I electronically filed my taxes. Accepted. When my son tried to file his taxes, they were rejected because he was already "claimed" on my taxes. It's now the 14th of April.
I assume I need to amend my taxes, (via mail), and resubmit son's taxes. What is the soonest he can resubmit and not have his taxes rejected again? Did I mention it's April 14th?
Does the rejection count as a "postmark" as far the the filing deadline?
Does/do he/we need to file an extension?
Thanks.
