@jburatti If your son did not say on his own return that he could be claimed as someone else's dependent, when you try to e-file a return that does claim him, your e-file will be rejected for duplicate use of his SSN. Then the only way you will be able to file and claim him as a dependent will be to file by mail. You will have to print, sign and date your return in ink, and mail it in. Your son will need to amend his return to change the way he answered the question in MY INFO regarding whether he could be claimed.
