If I'm not paying for my tuition do i still have to file my 1098-T when doing my taxes? My parents are filing it on their taxes.

If you are being claimed as a dependent you do not enter the Form 1098-T on your tax return.  Your parent's would enter the 1098-T on their tax return.

Q. Do I have to file my 1098-T when doing my taxes, if my parents are filing it on theirs?

A. Usually not.  If box 5 of your 1098-T is more than box 1, then probably yes. If box 1 is less than $4000 more than box 5, then there may be a reason for you to file.  If so, reply back for details.
