Can we deduct student loan interest payments made by us while our son is in school? The loans are in my son's name and either we or his grandmother are cosigners.

As a cosigner, you are legally obligated to pay the loan, so if you meet all the other requirements, yes, you can deduct it.   You can claim the deduction if all of the following apply:

• You paid interest on a qualified student loan in tax year 2022
• You or your spouse, if filing jointly, can't be claimed as dependents on someone else's return. (You can take the deduction as a student. If you're a parent making payments on your dependent student’s loan, you can also take the deduction)
• You're legally obligated to pay interest on a qualified student loan
• Your filing status isn't married filing separately
• Your MAGI is less than a specified amount, which is set annually

Claiming Student Loan Interest

Yes, you can deduct the interest on the loan you co-signed, but not the one grandma co-signed for. 

The requirements are:

1. You are legally obligated to pay it (co-signing meets this requirement)
2.  You actually pay it.
3.  The student was your dependent at the time the loan was used to pay for school
