If you made student loan payments last year, there is a good chance the federal government owes you a small discount on your taxes. The student loan interest deduction lets you subtract up to $2,500 of the interest you paid from your taxable income. It is one of the few deductions that works even if you take the standard deduction, which is why almost every borrower should claim it.
This guide walks through who qualifies, how the income phase-out works, and exactly where the deduction goes on your return.
What the Deduction Actually Does
The student loan interest deduction is an above-the-line deduction. That means it comes off the top of your return, reducing your adjusted gross income (AGI), before you ever decide between the standard deduction and itemizing. A lower AGI can help with other things too: it can protect eligibility for credits like the Earned Income Tax Credit and keep you under income limits for other deductions.
You can deduct the lesser of:
- The actual interest you paid during the year, or
- $2,500.
If your servicer reported $900 of interest on your Form 1098-E, your deduction is $900. If they reported $3,400, your deduction is capped at $2,500.
Who Can Claim It
You generally qualify if all of the following are true:
- You (or your spouse, if filing jointly) paid interest on a qualified student loan.
- Your filing status is single, head of household, qualifying surviving spouse, or married filing jointly. Married filing separately does not qualify.
- No one claims you as a dependent on their return.
- Your modified AGI is under the phase-out ceiling (see below).
A qualified student loan is one you took out solely to pay for education expenses for you, your spouse, or a dependent. This includes federal loans (Direct, FFEL, Perkins) and most private student loans. It does not include loans from a relative or a qualified employer plan.
The Income Phase-Out (2026 Figures)
The deduction shrinks and then disappears as your income rises. The phase-out is based on modified adjusted gross income (MAGI), which is your AGI plus a few additions (mostly foreign exclusions and tax-exempt interest).
| Filing Status | Phase-Out Begins | Phase-Out Ends (No Deduction) |
|---|---|---|
| Single / Head of Household | $85,000 | $100,000 |
| Married Filing Jointly | $175,000 | $205,000 |
| Married Filing Separately | Not eligible at any income | |
Inside the phase-out range the deduction is reduced proportionally. For example, a single filer with MAGI of $92,500 (halfway through the $15,000 window) gets roughly half the full deduction, about $1,250. Use our deduction calculator to find your exact number without doing the proration by hand.
Where It Goes on Your Return
You report the deduction on Schedule 1 (Form 1040), Part II, line 21, "Student loan interest deduction." The total from Schedule 1 flows up to line 10 of Form 1040 and reduces your AGI. You do not need to itemize, and you do not attach your 1098-E, but you should keep it with your records.
Most tax software asks whether you paid student loan interest and fills in the line automatically once you enter the amount from your 1098-E.
How to Find the Number You Need
Your loan servicer sends a Form 1098-E by January 31 if they collected $600 or more of interest. Box 1 shows the total interest received during the year. That is the number to enter.
Two wrinkles to watch:
- Loan origination fees. For federal student loans, a portion of certain fees may count as interest. Your servicer generally includes them in Box 1.
- Capitalized interest. Interest added to your balance when a deferment or forbearance ended is reported in Box 1 for the year it was paid, not the year it capitalized.
Common Mistakes
- Assuming you must itemize. You do not. This is the most missed opportunity.
- Overlooking parent loans. A parent who is the borrower on a Parent PLUS loan claims the interest, even if the child makes the payments.
- Filing separately while married. If you file separately, the deduction is unavailable. Running a joint return is often worth it just to unlock this and other breaks.
- Forgetting the year you paid off the loan. The final year often has a chunk of interest that is easy to miss.
How Much Is It Really Worth?
Because the deduction lowers taxable income, the cash value equals the deduction times your marginal rate. The table below shows the savings at common brackets, assuming you max out the $2,500 deduction.
| Marginal Rate | Tax Saved on Full $2,500 Deduction |
|---|---|
| 10% | $250 |
| 12% | $300 |
| 22% | $550 |
| 24% | $600 |
| 32% | $800 |
It is not life-changing money, but it is free money for paperwork you already have. Most borrowers leave it on the table only because they do not realize the standard deduction does not block it.
The Bottom Line
If you paid student loan interest and your income is under the phase-out limit, claim the deduction on Schedule 1 regardless of whether you itemize. Pull the amount from your 1098-E, confirm your phase-out with our calculator, and let it shave a few hundred dollars off your bill.

Frequently Asked Questions
How much is the student loan interest deduction worth?
It is worth up to $2,500 of interest you paid, taken as an above-the-line deduction. The cash savings equal that amount times your marginal rate. At 22%, the full deduction saves about $550.
Do I need to itemize to claim it?
No. It is reported on Schedule 1 (Form 1040) and works on top of the standard deduction, so most taxpayers can claim it.
At what income does it phase out?
For 2026, phase-out starts at $85,000 (single) or $175,000 (joint) and ends at $100,000 (single) or $205,000 (joint). Married filing separately cannot claim it.
Can a parent claim it for a child's loans?
Only the borrower can claim it. A parent who holds a Parent PLUS loan claims the interest; the student claims it if they are the borrower, even with parental help on payments.
