You can deduct up to $2,500 in student loan interest per year on your federal tax return, but only if your income falls below a certain threshold

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 tax credit — it does not reduce your taxes dollar-for-dollar. Instead, it reduces the income amount the IRS uses to calculate what you owe, which typically saves you between $250 and $750 depending on your tax bracket and how much interest you paid.

You claim this deduction on Form 1040 or Form 1040-SR when you file your federal taxes. You do not need to itemize deductions to use it. The deduction phases out if your Modified Adjusted Gross Income (MAGI) exceeds certain limits — those limits vary by filing status and change each year.

Key Takeaways

  • The maximum deduction is $2,500 per year, but you can only deduct the interest you actually paid, so if you paid $1,200 in interest, that is what you deduct.
  • The deduction begins to phase out at $75,000 MAGI for single filers and $155,000 for married couples filing jointly, and disappears entirely at higher income levels that vary by year.
  • You must have been legally obligated to pay the interest — you cannot deduct interest your parents paid on a Parent PLUS loan, even if you repay them later.
  • Interest on federal loans (Direct Loans, Stafford Loans, Perkins Loans) and private student loans both count, but only if the loan was taken solely to pay education expenses.
  • You will need Form 1098-E from your loan servicer, which reports the interest you paid during the tax year.

Income limits and phase-out ranges by filing status

The deduction starts to reduce once your MAGI crosses a threshold. For 2024, the phase-out begins at $75,000 for single filers and $155,000 for married couples filing jointly. The deduction disappears completely at $90,000 for single filers and $185,000 for married couples filing jointly. These thresholds shift each year, so check the IRS website or your tax software for the current year's limits.

MAGI is usually your Adjusted Gross Income (AGI) with certain deductions added back. For most people, MAGI and AGI are the same number. If your income is below the phase-out range, you can deduct the full amount of interest you paid (up to $2,500). If your income falls within the phase-out range, the deduction shrinks by $1 for every $15 of income above the threshold. If your income exceeds the upper limit, you cannot deduct any student loan interest that year.

What counts as deductible interest

Only interest counts — principal payments do not. Your loan servicer will send you Form 1098-E each January showing the interest you paid during the previous calendar year. Use that number as your deduction, up to the $2,500 cap.

The loan must have been taken for education expenses: tuition, fees, books, supplies, room and board (if you were at least a half-time student), and equipment required for school. Interest on loans used for other purposes does not may have access to. Both federal and private student loans count, as long as the money went to education.

You must have been the person legally obligated to pay the interest. If your parents took out a Parent PLUS loan and paid the interest themselves, they can deduct it — you cannot, even if you later repay them. If you are paying interest on a loan your parents took out and put in your name, you can deduct it because you are the obligated borrower.

When you cannot claim the deduction

You cannot deduct student loan interest if someone else can claim you as a dependent on their tax return. This usually means you are under 24 and your parents claim you. Even if you paid the interest yourself, the deduction is not available to you that year.

You also cannot deduct interest if you are married filing separately. The IRS does not allow this deduction for that filing status, regardless of income.

If you are in an income-driven repayment plan and your monthly payment is $0 because your income is too low, you still paid interest (it accrues even when your payment is zero), and you can still deduct it if you meet the other requirements.

How to claim the deduction on your tax return

Gather Form 1098-E from your loan servicer. This form arrives by January 31 each year and shows the interest you paid during the previous year. If you did not receive it, contact your servicer — they are required to send it.

On Form 1040 or Form 1040-SR, find the line for student loan interest deduction. Most tax software will ask you for the amount from Form 1098-E and calculate whether you are within the income limits. If you are within the phase-out range, the software will reduce your deduction by the correct amount.

If your income exceeds the upper phase-out limit, you cannot claim any deduction that year, even if you paid substantial interest. You will have to skip this line entirely.

Deduction versus tax credit: which is better

The student loan interest deduction and the American Opportunity Tax Credit or Lifetime Learning Credit are separate. You cannot use the same education expenses to claim both. However, you can claim the interest deduction and a tax credit in the same year if they apply to different expenses or different loans.

A tax credit is usually more valuable because it reduces your tax bill directly. A deduction reduces your taxable income. For example, a $2,500 deduction might save you $500 to $750 in taxes (depending on your tax bracket), but a $2,500 tax credit saves you $2,500. If you have a choice, prioritize the credit. Your tax software will help you figure out which combination saves you the most.

What happens if your income changes mid-year

Your deduction is based on your MAGI for the entire tax year, not your income at the time you paid the interest. If you earned $70,000 in January through June and then lost your job, your annual MAGI is still $70,000, and you can claim the full deduction. If you earned $80,000 and are in the phase-out range, the deduction shrinks even though you paid interest when your income was lower.

This matters if you are self-employed or have variable income. Calculate your full-year MAGI before deciding whether to claim the deduction.

Frequently Asked Questions

Can I deduct interest on Parent PLUS loans I am repaying?

No. Only the parent who borrowed the loan can deduct the interest. If your parents took out the loan and you repay them, you cannot deduct it. If you took out a Parent PLUS loan yourself (some graduate students can), you can deduct the interest you paid.

What if I paid more than $2,500 in interest?

You can only deduct up to $2,500 per year. The excess does not carry over to future years. If you paid $3,000 in interest, your deduction is capped at $2,500, and the remaining $700 is lost.

Do I need to itemize deductions to claim this?

No. The student loan interest deduction is an "above-the-line" deduction, meaning you can claim it whether you take the standard deduction or itemize. This makes it more valuable than many other education deductions.

Can I deduct interest if I am on an income-driven repayment plan?

Yes. Interest accrues even when your monthly payment is $0 under income-driven plans. If you paid interest (or if it was capitalized and added to your loan balance), you can deduct it as long as you meet the income and dependent requirements.

What if I did not receive Form 1098-E from my servicer?

Contact your loan servicer directly — they are required to send it by January 31. If they cannot locate your form, ask them to provide a statement showing the interest you paid. You can use that statement to claim the deduction, though you may want to keep a copy with your tax records.
