You can deduct up to $2,500 of student loan interest per year on your federal tax return, but only if your income falls below a certain threshold and you meet other conditions.
The student loan interest deduction lets you reduce your taxable income by the amount of interest you paid on may have access to student loans during the tax year. This is different from a tax credit — it lowers the income the IRS taxes, rather than reducing your tax bill directly. You claim it on Form 1040 or Form 1040-SR, and you do not need to itemize deductions to use it.
The deduction phases out as your income rises. For the 2024 tax year, the phase-out begins at $75,000 for single filers and $155,000 for married couples filing jointly. Once your income exceeds $90,000 (single) or $185,000 (married filing jointly), you cannot claim any deduction. These income thresholds change each year, so check the IRS website or your tax software for the year you are filing.
Key Takeaways
- The maximum deduction is $2,500 per year, but you can only deduct the actual interest you paid if it was less than that amount.
- Your income must be below the phase-out range for your filing status to claim any deduction at all.
- Only interest on federal student loans and certain private student loans counts — not principal payments or Parent PLUS loans you took out.
- You must be claimed as a dependent on someone else's tax return to be ineligible, even if you paid the interest yourself.
- Your loan servicer sends Form 1098-E in January showing how much interest you paid the previous year.
Which student loans may have access to for the deduction
Federal student loans almost always may have access to: Direct Loans, Federal Family Education Loans (FFEL), and Perkins Loans all count. The interest you paid on these loans during the tax year is deductible, as long as you meet the income and dependency rules.
Private student loans can may have access to too, but only if they were used to pay for education expenses at an accredited school. The loan must have been taken out in your name — not a parent's name — and the school must be may be able to access for federal student aid programs. If you are unsure whether your private loan qualifies, check the Form 1098-E your lender sends, or contact them directly.
Parent PLUS loans do not may have access to for this deduction, even though they are federal loans. If a parent took out a Parent PLUS loan to pay for your education, the parent can deduct the interest they paid, but you cannot. Loans used to refinance student loans into a private loan also lose their deductibility — once you refinance federal loans into a private loan, the interest on the new loan may not may have access to.
Income limits and how the phase-out works
Your Modified Adjusted Gross Income (MAGI) determines whether you can claim the deduction. MAGI is usually the same as your adjusted gross income (AGI) shown on your tax return, though some types of income can change this calculation. The IRS instructions for Form 1040 explain which income types affect MAGI for this deduction.
The phase-out is a gradual reduction. If your MAGI falls within the phase-out range for your filing status, you can deduct a reduced amount. For example, in 2024, a single filer with MAGI of $82,500 is halfway through the $75,000 to $90,000 phase-out range and can deduct roughly $1,250 instead of the full $2,500. Tax software calculates this automatically, but you can also work it out by hand using the IRS worksheet in the Form 1040 instructions.
If you are married and file separately, the phase-out range is $0 to $15,000 — much narrower than for other filing statuses. This means married couples filing separately rarely benefit from the deduction.
How to claim the deduction on your tax return
Start with Form 1098-E, which your loan servicer mails to you by January 31 each year. This form shows the interest you paid during the previous tax year. If you paid interest on multiple loans, the form totals them. Keep this form with your tax records, though you do not mail it to the IRS.
On your tax return, enter the deduction on line 21 of Form 1040 or Form 1040-SR, labeled "Student loan interest deduction." If your income is within the phase-out range, use the worksheet in the Form 1040 instructions to calculate the reduced amount. Most tax software asks you to enter the amount from Form 1098-E and handles the phase-out calculation for you.
You can deduct interest you paid even if you did not make the full payment yourself — for example, if a parent or spouse paid part of your interest, you can still claim the full amount as long as the loan is in your name and you meet the other rules. However, you cannot deduct interest paid by someone else on a loan in their name, such as a parent's Parent PLUS loan.
When you cannot claim the deduction
If someone else claims you as a dependent on their tax return, you cannot claim the student loan interest deduction, even if you paid all the interest yourself and the loan is in your name. This rule applies whether the person claiming you is a parent, guardian, or another relative. If you are no longer a dependent, you can claim the deduction starting the year after the dependency ends.
You also cannot claim the deduction if your income exceeds the phase-out ceiling for your filing status. There is no partial deduction once you cross that threshold — the deduction disappears entirely. Married couples filing separately almost never benefit because their phase-out range is so narrow.
If you did not pay any interest during the tax year — for example, because your loans are in deferment or forbearance — there is nothing to deduct. You can only deduct interest that was actually paid, not interest that accrued or was added to your loan balance.
The difference between the interest deduction and other tax benefits
The student loan interest deduction is separate from the American Opportunity Tax Credit and the Lifetime Learning Credit, which are credits for education expenses like tuition and fees. You can claim both the interest deduction and an education credit in the same year if you meet the rules for each one, though they use different income thresholds and have different phase-out ranges.
A tax credit is generally more valuable than a deduction because it reduces your tax bill dollar-for-dollar, whereas a deduction only reduces the income that gets taxed. However, the student loan interest deduction is available to more people because it has higher income limits than some education credits.
If you are paying down student loans while also paying tuition for yourself or a dependent, you may be able to use both benefits. Your tax software or a tax professional can help you figure out which combination saves you the most.
Frequently Asked Questions
Can I deduct student loan interest if I am in income-driven repayment?
Yes. Income-driven repayment plans do not affect your ability to claim the deduction. You can deduct the actual interest you paid during the year, regardless of which repayment plan you are on. If your plan results in unpaid interest being added to your loan balance, you cannot deduct that unpaid interest — only what you actually paid.
What if I paid more than $2,500 in student loan interest?
You can only deduct up to $2,500 per year, even if you paid more. The excess does not carry over to future years. If you are married filing jointly and both spouses paid student loan interest, each person can deduct up to $2,500 on the same return, for a household maximum of $5,000.
Do I need to file Form 1098-E with my tax return?
No. Form 1098-E is for your records only. You enter the deduction amount on your tax return, but you do not attach the form to your return or mail it to the IRS. Keep it with your tax documents in case the IRS asks questions later.
Can I deduct interest on student loans I took out for graduate school?
Yes, as long as the loans are in your name and meet the other rules. Federal Direct Graduate PLUS loans and private graduate loans both may have access to, provided the private loan was used for education at an accredited school. The same $2,500 annual limit and income phase-out explore.
What happens to the deduction if I get married or my income changes?
Your filing status and income for the year you are filing determine your deduction. If you married during the year, you can file jointly (which gives you higher income limits) or separately (which gives you much lower limits). If your income changed during the year, use your year-end MAGI to determine whether you fall within the phase-out range.
