Student Loan Interest Deduction: Who Qualifies and How to Claim It
You can deduct up to $2,500 of student loan interest on your federal return, and because it's an above-the-line deduction you don't need to itemize. To qualify you must be legally obligated to repay the loan, the student must be enrolled at least half-time, and your income must fall below the phaseout — roughly $75,000–$90,000 for single filers and $150,000–$185,000 for joint filers in 2025.
What the Student Loan Interest Deduction Does
The student loan interest deduction lets you reduce your taxable income by the interest you paid on qualified student loans, up to $2,500 per year. It's an above-the-line deduction, meaning you claim it before calculating adjusted gross income — so you benefit even if you take the standard deduction and never itemize. For someone in the 22% tax bracket, a full $2,500 deduction cuts federal tax by about $550. It also lowers AGI, which can improve eligibility for other credits and deductions.
Who Qualifies for the Deduction
Four conditions must hold. First, you must be legally obligated to repay the loan — a loan in your name, a Parent PLUS loan, or one you co-signed. Second, you must actually pay interest during the tax year. Third, the student must be enrolled at least half-time in a degree or certificate program at the time the interest accrued. Fourth, the student can't be claimed as a dependent on anyone's return that year, and you can't file as married filing separately. Both federal and private student loans qualify, as long as the money was used solely for qualified higher education expenses.
Income Limits and the Phaseout
The deduction phases out as your modified adjusted gross income (MAGI) rises. For 2025, single filers get the full deduction below about $75,000 MAGI and lose it entirely at $90,000; married joint filers phase out between roughly $150,000 and $185,000. The deduction shrinks proportionally within the phaseout band — for example, a single filer at $82,500 deducts about half the amount. The thresholds are adjusted for inflation each year, so check the current IRS numbers before you file.
How to Claim the Deduction
Your loan servicer must send Form 1098-E each January showing the interest you paid — most servicers are required to issue it when interest exceeds $600, and many issue it regardless. On Form 1040, you report the deduction on Schedule 1 (line 21) as an adjustment to income. If you don't receive a 1098-E, you can still deduct the interest you actually paid — pull your payment history from your servicer and enter the correct amount. You don't attach anything to your return, but keep the form in your records.
Common Mistakes and Traps
The biggest trap is using a home equity loan to pay for education — interest on it does not qualify for the student loan interest deduction, since it's not a qualified education loan. Parents who help a child pay a loan in the child's name can't deduct that interest themselves, and the child can't deduct it either if the parents claim them as a dependent. Married couples who file separately lose the deduction entirely. If you refinance, the new loan still qualifies as long as it's used solely for qualified education expenses and you remain legally obligated.
Frequently Asked Questions
Can I deduct student loan interest?
Yes, up to $2,500 per year, if you're legally obligated to repay the loan, you paid interest during the year, the student was enrolled at least half-time, you're not claimed as a dependent, and your income is below the phaseout range. It's an above-the-line deduction, so you don't need to itemize.
What is the income limit for the student loan interest deduction?
For 2025, the deduction phases out for single filers with modified AGI between roughly $75,000 and $90,000, and for married joint filers between $150,000 and $185,000. Above the top of the range you get no deduction. The limits are adjusted for inflation each year.
Can my parents deduct the interest on my student loans?
Only if they are legally obligated to repay the loan — for example, a Parent PLUS loan or a loan they co-signed. If they simply help you pay a loan that's in your name, they can't deduct it, and you can only claim the deduction yourself if you're not claimed as a dependent.
Where do I find the interest I paid on my student loans?
Your loan servicer sends Form 1098-E each January showing the interest you paid. Servicers must issue it when interest exceeds $600, and most issue it at any amount. If you didn't receive one, check your servicer's online payment history — you can deduct the interest you actually paid.
