Q. I want to know if it is legal and okay to file a return with no income.
A. Yes. But, it's not necessary unless you have a purpose.
Why do you think you need to or want to file a tax return?
Is your parent claiming you as a dependent?
Are you trying to claim the refundable education credit*.
*The American Opportunity credit (AOTC) is worth up to $2500. But, only $1000 is refundable (the other $1500 can only be used against an actual tax liability). The AOTC can only be claimed 4 times, in your undergrad career. You may not want to use one for $1000 if it will later be worth $2500 (you are allowed to amend if you change your mind).
