"I am worried that if I file jointly with my husband this year that it will take away my refund money from the school."
You need to explain what that means. I have never heard that before.
Married filing jointly (MFJ) is almost always better. As others have said, you are prohibited from claiming the tuition credit if you file Married filing Separately (MFS). Those are you only two choices. You are not allowed to file Single.
Many loan companies require you to file MFS in order to qualify for reduced student loan payments. That's a choice you have to make in that situation.
If you're thinking of allowing your parents to claim you as a dependent, so they can get the tuition credit, see that discussion at
