Question: what if my 1098-t is blank?
Answer: The school reports the amount paid in Box 1 of the form. In tax years prior to 2018, the school could report the amount billed in Box 2 of form 1098-T. This box is now blank. Generally, if you used the amount in Box 2 in a previous year, the IRS would ask for proof that the payments were made to the school.
