1098 t

Simple answer: No. You do not file a tax return, if you have no income*. 

If your parents (or somebody else) claims you as a dependent, they may claim an education credit or deduction, based on your 1098-T form, even though the form is under your name and SS#.

*There are exceptions.  If you are a student, over age 23, and are not claimed (or eligible to be claimed) as a dependent by someone else  you may be eligible for the up to $1000 refundable American Opportunity (tuition) Credit. That credit is not dependent on having either kids or earned income. You must be at least a half time undergraduate student. There's even a loop hole available to claim the credit, if you are on scholarship**.

Another exception: if box 5 of your 1098-T exceeds box 1 by more that $12,200, you have taxable scholarship and must file a tax return. 

**Another exception: If you are claimed as a dependent, and your  scholarships exceed your qualified expenses; and your parents want to claim the tuition credit; you must file a tax return and declare some of the scholarship as taxable income, in order to allow your parent to claim expenses for the credit.
