student loan interest

If you co-signed and you made the payments you can use the deduction.

STUDENT LOAN INTEREST

Only the person whose name is on the student loan and who is legally obligated to pay the loan can deduct the student loan interest.  If you did not sign or co-sign for the loan you cannot deduct the interest.

You cannot deduct student loan interest if you are being claimed as someone else’s dependent, or if you are filing as married filing separately.

The student loan interest deduction can reduce your taxable income by up to $2500

There is a phaseout for the Student loan interest deduction, which means the amount you can deduct gets reduced when your modified adjusted gross income hits certain income levels and is even eliminated at certain income levels -  

•If your filing status is single, head of household, or qualifying widow(er), then the phaseout begins at $65,000 until $80,000, after which the deduction is eliminated entirely.

•If your filing status is married filing joint, then the phaseout beings at  $130,000 until $160,000, after which the deduction is eliminated entirely.

 Enter the interest you paid for your student loan by going to Federal>Deductions and Credits>Education>Student Loan Interest Paid in 2020 (Form 1098E)

Look on your 2020 Schedule 1 line 20 to see your student loan interest deduction

@pko2021  said " I cannot claim him as a dependent because he made to much money from his job while going to school full time".

There are two types of dependents, "Qualifying Children"(QC) and standard ("Qualifying Relative" in IRS parlance even though they don't have to actually be related). There is no income limit for a QC but there is an age limit, student status, a relationship test and residence test.

A child of a taxpayer can still be a “Qualifying Child” (QC) dependent, regardless of his/her income, if:

1. He is under age 19, or under 24 if a full time student for at least 5 months of the year, or is totally & permanently disabled
2. He did not provide more than 1/2 his own support. Scholarships are excluded from the support calculation
3. He lived with the parent (including temporary absences such as away at school) for more than half the year

So, it doesn't matter how much he earned. What matters is how much he spent on support. Money he put into savings does not count as support he spent on him self.

The support value of the home, provided by the parent, is the fair market rental value of the home plus utilities & other expenses divided by the number of occupants.

The IRS has a worksheet that can be used to help with the support calculation. See: http://apps.irs.gov/app/vita/content/globalmedia/teacher/worksheet_for_determining_support_4012.pdf
