You can deduct up to $2,500 of student loan interest paid in a tax year, but only if your income and filing status meet the limits
The student loan interest deduction lets you subtract interest you paid on federal or private student loans from your taxable income. This is not a credit that reduces your tax bill dollar-for-dollar — it reduces the income the IRS counts, which then lowers your tax bill by a smaller amount. The maximum deduction is $2,500 per year, and it applies only to interest, not to principal payments.
You claim this deduction on Form 1040 or Form 1040-SR when you file your federal tax return. You do not need to itemize deductions to use it. However, the deduction phases out — meaning it shrinks and then disappears — if your Modified Adjusted Gross Income (MAGI) exceeds certain thresholds that depend on your filing status.
Key Takeaways
- The maximum student loan interest deduction is $2,500 per year, and it applies only to interest paid, not principal.
- The deduction phases out completely if your MAGI exceeds $85,000 (single filers) or $170,000 (married filing jointly) in 2024, with different thresholds for other filing statuses.
- You must have been legally obligated to pay the interest, and you cannot claim the deduction if someone else — such as a parent — paid the interest on your behalf.
- Private student loans and federal loans both may have access to, but only interest paid during the tax year counts; interest you capitalized or deferred does not.
- You report the deduction on line 21 of Form 1040, and your loan servicer will send you Form 1098-E showing how much interest you paid.
Income limits and how the deduction phases out
Your filing status and Modified Adjusted Gross Income determine whether you can claim the full $2,500 deduction, a partial deduction, or no deduction at all. The phase-out ranges are set by the IRS and change each year.
For the 2024 tax year (filed in 2025), the phase-out ranges are:
| Filing Status | Phase-Out Begins | Phase-Out Ends (No Deduction) |
|---|---|---|
| Single | $75,000 | $90,000 |
| Married Filing Jointly | $150,000 | $180,000 |
| Married Filing Separately | $0 | $15,000 |
| Head of Household | $75,000 | $90,000 |
| may have access to Widow(er) | $150,000 | $180,000 |
If your MAGI falls within the phase-out range, the deduction shrinks by $1 for every $2 of income above the lower threshold. For example, if you file as single with a MAGI of $80,000, you are $5,000 above the $75,000 threshold. Your deduction reduces by $2,500 (half of $5,000), leaving you with a $0 deduction. The IRS publishes updated phase-out ranges each year, so check the current year's limits before you file.
What counts as student loan interest you can deduct
Interest paid on any loan used to pay for your own education, or your spouse's or dependent's education, can count toward the deduction. This includes federal loans (Stafford, Unsubsidized Stafford, PLUS loans) and private student loans from banks or other lenders.
The loan must have been taken out in your name or your spouse's name (if filing jointly). You cannot deduct interest paid on a parent's PLUS loan, even if you repay it on their behalf. The education must have been pursued at an accredited school — typically a college, university, or vocational program recognized by the U.S. Department of Education.
Only interest actually paid during the tax year counts. If your loan servicer capitalized interest (added unpaid interest to your principal balance) or if you deferred interest payments, that amount does not count in the year it was capitalized or deferred. You can only deduct interest when you actually pay it.
How to claim the deduction on your tax return
You report the student loan interest deduction on line 21 of Form 1040 or Form 1040-SR. You do not need to attach any forms or receipts, but you should keep your records in case the IRS asks for proof.
Your loan servicer will send you Form 1098-E by January 31 each year, showing the interest you paid in the previous tax year. Use the amount on Box 1 of that form as your deduction, unless you paid more interest than appears on the form (which can happen if you have multiple loans or servicers). If you paid more, you can deduct up to $2,500 total, but you will need to calculate the amount yourself and keep documentation.
If you file electronically, tax software will prompt you to enter the amount from Form 1098-E. If you file by paper, write the amount on line 21 and attach a copy of Form 1098-E to your return.
When you cannot claim the deduction
You cannot claim the deduction if someone else paid the interest on your behalf. This is a common situation with parent PLUS loans or when a parent makes payments on a child's federal loan. Even though you may have been responsible for the debt, only the person who actually paid the interest can claim the deduction.
You also cannot claim the deduction if you are claimed as a dependent on someone else's tax return, or if your filing status is married filing separately and your spouse does not also claim the deduction. Additionally, if your MAGI exceeds the phase-out range for your filing status, you have no deduction to claim.
If you are in school and your loan is in deferment or forbearance, you may not be paying interest during that time. Once payments resume, you can begin claiming the deduction again for interest you actually pay.
Student loan interest deduction versus other tax benefits
The student loan interest deduction is separate from other education tax credits, such as the American Opportunity Tax Credit and the Lifetime Learning Credit. You can claim the interest deduction and a tax credit in the same year, but the credit applies to tuition and fees, not to loan interest.
If you are repaying loans under an income-driven repayment plan, you may have forgiven loan balances after 20 or 25 years of payments. Forgiven amounts are generally treated as taxable income in the year of forgiveness, but the student loan interest deduction does not affect that calculation. The deduction only reduces your taxable income in years when you are actively paying interest.
Frequently Asked Questions
Can I deduct interest on a parent PLUS loan if I repay it?
No. Only the parent who borrowed the PLUS loan can claim the interest deduction, even if you make the payments. If your parent allows you to claim them as a dependent, they can claim the deduction instead. If you are independent, your parent can still claim it if they meet the income limits.
What if I paid more than $2,500 in student loan interest this year?
You can deduct only up to $2,500, even if you paid more. The excess does not carry over to future years. However, if you have a spouse and file jointly, each of you can deduct up to $2,500, for a household maximum of $5,000.
Do I need Form 1098-E to claim the deduction?
Your servicer should send Form 1098-E, but if you do not receive it or it shows the wrong amount, you can still claim the deduction. Keep your loan statements or payment records showing the interest you paid, and report the correct amount on your return.
Can I claim the deduction if I am on an income-driven repayment plan?
Yes. Income-driven plans do not affect your ability to claim the interest deduction. You deduct the interest you actually paid during the year, regardless of which repayment plan you are on.
Does the deduction reduce my MAGI for other tax purposes?
No. The student loan interest deduction reduces your taxable income for federal income tax purposes, but it does not reduce your MAGI for calculating other benefits or credits. MAGI is calculated before the deduction is applied.
