Student Loan Interest Deduction: Up to $2,500 Off Your 2025 Taxes

The Student Loan Interest Deduction lets you deduct up to $2,500 of interest paid on qualified student loans in 2025. It's an above-the-line deduction — meaning you can take it whether you itemize or take the standard deduction. At a 22% marginal rate, that's up to $550 of federal tax savings; at 24%, $600. Easy to miss if your loan servicer didn't send a Form 1098-E.

Who qualifies

• You paid interest on a qualified student loan in 2025 (federal or private).
• The loan was for you, your spouse, or your dependent at the time you took it out.
• The loan was used for qualified higher education expenses (tuition, books, room & board, fees).
• You're legally obligated to pay the interest (typically borrower or co-signer making payments).
• Filing status is not married filing separately.
• Your MAGI is below the phase-out limits.

2025 income limits

• Single / HoH — phase-out $85,000 to $100,000 (no deduction above $100,000)
• MFJ — phase-out $170,000 to $200,000 (no deduction above $200,000)

How much can you actually deduct?

Up to $2,500, capped at the actual interest you paid. If your servicer reports $1,800 of interest on your 1098-E, that's your maximum. If you paid $3,200, you're capped at $2,500. If you paid $400, you deduct $400.

Where to find the number

Form 1098-E from your loan servicer. Federal loans through Nelnet, EdFinancial, MOHELA, and others all issue these online in January or February. Private servicers do too, though some don't issue if interest was under $600. In that case, log into your servicer account and find total interest paid for the year — it still qualifies.

How to claim it

It goes on Schedule 1 of Form 1040, line 21. Most tax software handles it automatically when you import 1098-E data or enter it manually. You don't itemize to claim it.

What doesn't qualify

Interest paid on a loan from a family member, employer plan, or related party. Payments made by someone other than you and applied as a gift may still count for you as the borrower if you're legally on the hook (the IRS allows you to 'be treated as receiving' the payment, then deducting the interest).

Real-world example

Riley earns $62,000 single and paid $2,300 in student loan interest in 2025. He's under the phase-out, so the full $2,300 is deductible. At a 22% marginal rate, that's $506 of federal tax saved — directly boosting his refund by the same amount.
