NEXT, and a separate subject is Education Credits.
If more was PAID for education expenses than what was received in Scholarships and/or other financial assistance, the might be an Education Credit available.
If there is an education credit available, the person that claims the student gets that credit.
To claim the credit, enter Form 1098-T which should have been issued to the student. Sometimes the student needs to go online to get it from the school.
Box 1 on the 1098-T reports what was PAID to the school for tuition expense.
Box 5 on the 1098-T reports what was posted in Scholarships for the year.
If Box 1 is larger than Box 5, you might get a credit.
If Box 5 is larger than Box 1, the student might need to claim taxable income.
