Hi, I have the exact same issue; I filed my dependents return for him and the box indicating he can still be claimed as a dependent was correctly marked and indicated. To the OPs question, if I'm getting a rejection on my taxes, wouldn't that also mean that any one else (intentionally or erroneously) trying to use their SSN to would be rejected as well? I submitted his return 10 min before submitting mine, could the order of submission be an issue? This is his 3rd year filing and we've never had this issue before with e-filing. Thank you in advance for any clarity you can provide!
