Get your taxes done using TurboTax

So you don't have a choice in the matter, it depends on what Tax Law dictates for your specific circumstances.

As a full-time student under age 24, you can NOT claim your own exemption UNLESS (1) You paid for over 50% of all of your support *OR* (2) You have PERMANENTLY moved out of your parents home.  If either of those are true, then your mom can not claim you.
