Qualifying Dependent

Our 21 year old son filed his own returns but didn't check off the box "Can be claimed as dependent".

Because of this, our e-file submissions for Federal and State were both rejected.

 

Our son submitted the amendments last week and has already received the confirmation letter from the State (IN) that the request has been processed.

The Federal amendment on the other hand may take longer than 6 weeks  - past the filing deadline.

 

Since the error was only correct on the State, how should we resubmit taxes?

Remove him from "dependent" then e-file the Federal again?

For State, can we still claim him as dependent then file via paper forms?

 

Thank  you in advance!
