Who can deduct student loan interest?

The student loan interest deduction lets you reduce your taxable income by the amount of interest you paid on a qualified student loan. But not everyone can claim it. In short, you can deduct student loan interest if you paid interest on a qualified loan for yourself, your spouse, or your dependent, and your income falls within certain limits.

This guide explains who qualifies, what loans count, and how to claim the deduction on your taxes. We’ll also cover income limits and special rules for married couples.

Basic Eligibility Requirements

To deduct student loan interest, you must meet all of these conditions:

• You paid interest on a qualified student loan during the tax year.
• You are legally required to pay the interest (you are the borrower or co-signer).
• You are not filing as married filing separately.
• Your modified adjusted gross income (MAGI) is below the IRS limit.
• You are not claimed as a dependent on someone else’s tax return.

If you meet all these, you can claim the deduction even if you don’t itemize. It’s an “above-the-line” deduction, meaning you can take it in addition to the standard deduction.

Who Can Claim the Deduction?

You can claim the deduction if you paid interest on a loan taken out for higher education expenses. The loan must be for you, your spouse, or someone who was your dependent when the loan was taken out.

For Your Own Education

If you borrowed money to pay for your own college, graduate school, or vocational training, the interest is deductible as long as you meet income limits. You must have been enrolled at least half-time in a degree or certificate program.

For Your Spouse’s Education

If you took out a loan for your spouse’s education, you can deduct the interest. This applies even if you file jointly. The same half-time enrollment requirement applies.

For Your Dependent’s Education

Parents who take out loans (like PLUS loans) for a child’s education can deduct the interest if the child is claimed as a dependent. The child must be enrolled at least half-time. If you do not claim the child as a dependent, you cannot deduct the interest.

Income Limits and Phase-Outs

The deduction is phased out at higher income levels. For the 2025 tax year (filed in 2026), the phase-out ranges are:

Filing Status	Phase-Out Begins	Phase-Out Ends
Single / Head of Household	$80,000	$95,000
Married Filing Jointly	$165,000	$195,000

If your MAGI is above the phase-out range, you cannot claim the deduction at all. Between the start and end, your deduction is reduced. Married filing separately filers are not eligible at any income level.

What Counts as a Qualified Student Loan?

Not all loans qualify. The IRS defines a qualified student loan as one used solely to pay qualified higher education expenses. These expenses include tuition, fees, room and board, books, supplies, and equipment required for enrollment.

The loan must have been taken out for a student who was enrolled at least half-time. Also, the loan cannot be from a related person or a retirement plan. For example, a loan from a parent or a 401(k) does not qualify.

How to Claim the Deduction

You claim the student loan interest deduction on IRS Form 1040. The deduction is reported on Schedule 1, line 21. You do not need to itemize. Your lender will send you Form 1098-E if you paid at least $600 in interest, but you can claim the deduction even if you paid less.

To calculate your deduction, use the IRS worksheet in the Form 1040 instructions. You’ll need your 1098-E or your own records of interest paid.

Special Situations and Tips

Parents Who Co-Sign

If you co-signed a loan for your child but the child makes the payments, you cannot deduct the interest. The person who is legally required to pay and actually pays the interest gets the deduction. If you both pay, you can split the deduction, but the total cannot exceed $2,500.

Children Who Are Not Dependents

If you take out a loan for a child who is not your dependent (for example, if the child claims themselves), you cannot deduct the interest. The child might be able to deduct it if they are the borrower and paying.

Refinancing

If you refinance a qualified student loan, the new loan is still considered qualified as long as the proceeds are used to pay off the original loan. You can continue to deduct interest on the refinanced loan.

Common Mistakes to Avoid

• Claiming the deduction when you are claimed as a dependent.
• Forgetting to reduce the deduction if your income is in the phase-out range.
• Deducting interest on loans that were not used for qualified education expenses.
• Not keeping records of interest paid if you didn’t receive a 1098-E.

By avoiding these mistakes, you can maximize your deduction and stay compliant with IRS rules.

Final Thoughts

The student loan interest deduction is a valuable tax break for many borrowers. To claim it, you must meet the eligibility criteria, including income limits and loan qualifications. Check your MAGI, confirm your loan is qualified, and keep accurate records of interest paid. If you’re unsure, consult a tax professional or use IRS resources to ensure you claim the correct amount.
