After you file

If your dependent child did not indicate on his return that he could be claimed on someone else's return, when you try to e-file with him listed on your return as a dependent, your return will be rejected.  Your kid will need to file an amended return that indicates he can be claimed, and you will, unfortunately, need to print and mail your own return instead of e-filing.
