Step 1
Determine if you are eligible to take the deduction. To be eligible, you must not be married filing separately, and no one else can be claiming you as a dependent. Also, you are legally required to pay the interest on the loan. Paying on student loans for a family member without having your name officially attached to the loan does not count for the deduction.
-
Step 2
Determine if your income excludes you from taking the deduction. The student-loan interest deduction is eliminated for taxpayers with modified adjusted gross incomes above $145,000 and for individual filers above $70,000. A MAGI above these values disqualifies the taxpayer from taking the deduction.
-
Step 3
Calculate your eligible student-loan interest. Eligible student-loan interest is interest you are legally obligated to pay (your name is on the loan); the money must have been used only to pay for education expenses, and the loan cannot be from a person you are related to, or from an employer retirement plan like a 401(k) or 403(b). Total up all the interest paid for the year on all such loans. If this amount is less than $2,500, that is the eligible amount. If it is greater than $2,500, only $2,500 is the eligible amount.
-
Step 4
Determine if you can take the full deduction, or if you must take a reduced deduction. Taxpayers who are married filing jointly get a reduced deduction if their income is above $115,000 (but below $145,000), and single filers get a reduced deduction if their income is over $55,000 (but below $70,000). If your income is below $115,000 for married filing jointly, or below $55,000 filing single, go to Step 7.
-
Step 5
Calculate your reduced student-loan interest deduction. If you are filing as single, head of household or qualifying widow(er) and your income is between $55,000 and $70,000, your "reduction" is your MAGI minus $55,000, with that amount divided by $15,000. If you are married filing jointly, your "reduction" is your MAGI minus $115,000, with that amount divided by $30,000.
-
Step 6
Subtract your "reduction" from the amount of your eligible student-loan interest. This amount is your allowed student-loan interest income tax deduction.

Step 7
Enter the amount of your student -oan interest deduction on Form 1040 line 33.
