With college debt continuing to weigh heavily on millions of Americans, understanding the student loan interest deduction and how it interacts with itemized deductions is critical for maximizing your 2025 tax refund. Here’s what you need to know about limits, eligibility, and where it fits into your tax return.
Student Loan Interest Deduction in 2025
The IRS allows you to deduct up to $2,500 of qualified student loan interest paid during the year. Key rules:
- It’s an “above-the-line” deduction—claimed even if you take the standard deduction.
- Applies only to loans taken for qualified education expenses.
- You must be legally obligated to repay the loan.
This means you can benefit whether you itemize deductions or not, making it one of the most widely used tax breaks for individual taxpayers in the USA.

Income Phase-Out Limits for 2025
Not everyone qualifies for the full deduction. The benefit begins to phase out at higher income levels:
- Single filers: Phase-out begins around $75,000 MAGI and ends at $90,000.
- Married filing jointly: Phase-out begins at $155,000 MAGI and ends at $185,000.
- Married filing separately: Not eligible for this deduction.
If your income exceeds these thresholds, you cannot deduct student loan interest in 2025.
How It Differs from Itemized Deductions
Unlike deductions such as mortgage interest, state and local taxes, or charitable contributions, the student loan interest deduction does not require you to itemize on Schedule A. It is entered directly on Schedule 1 of Form 1040 and reduces your adjusted gross income (AGI).
This distinction is crucial: even if you claim the standard deduction—which for 2025 is $14,600 for singles and $29,200 for married couples—you can still take the student loan interest deduction if eligible.
Why It Matters for Tax Planning
- Lower AGI: Reducing AGI through this deduction can help you qualify for other tax credits.
- No double-dipping: You cannot claim interest paid with employer assistance programs as a deduction.
- Record keeping: Your lender should issue Form 1098-E if you paid more than $600 in interest.
Example: Standard Deduction vs. Itemizing
Maria, a single filer, paid $1,800 in student loan interest in 2025. She also claims the standard deduction of $14,600. Even though she doesn’t itemize, she still deducts the $1,800 on top of the standard deduction, lowering her taxable income even further.
Key Takeaways for 2025
- The student loan interest deduction is above the line—no need to itemize.
- Maximum deduction: $2,500 per return.
- Subject to income phase-outs for higher earners.
- Always check Form 1098-E for accuracy before filing.
