Why can't I eFile my tax return if my mom listed me as a dependent?

Now just go back and indicate on the first page of your 1040 FIT return that you are still a dependent of another taxpayer during the 2014 tax year and then your problem will be solved for that purpose and time and then you should be able to efile your own 1040 FIT return online during the 2015 tax filing season for this purpose at this time.

Hope that you find the above enclosed information useful. 02/11/2015

You are doing something wrong.

You can both efile but you both can not claim your dependency exemption.

Open your return and find the spot that says that "...you can be claimed as a dependent on someone else's return" and check it.

efile will not accept a 2nd tax return claiming the same SSN

you will have to file manually

You are trying to claim yourself on your return, that's why. Go back and indicate you cannot claim yourself, and problem solved.

You are doing something wrong. Go back and look at the box for whether or not you can be claimed by someone else.

"Pascal" has the answer.
