Student Loan Interest Deduction 2026: $2,500 Limit, MAGI Phaseout and Examples

Quick answer: For tax year 2026, an eligible taxpayer can deduct up to $2,500 of interest paid on qualified student loans. The deduction phases out between $85,000 and $100,000 of modified adjusted gross income for single, head of household and qualifying surviving spouse filers, and between $175,000 and $205,000 for married couples filing jointly. It is available without itemizing.

2026 student loan interest deduction limits

The $2,500 ceiling is per return, not per loan and not per borrower. A married couple filing jointly cannot claim $5,000 merely because both spouses paid interest. The IRS announced the 2026 phaseout thresholds in Revenue Procedure 2025-32.

Why this is a deduction, not a credit

The student loan interest benefit reduces income subject to federal tax; it does not reduce tax dollar for dollar. Because it is an adjustment to income, an eligible borrower can claim it while taking the standard deduction. It may also reduce adjusted gross income used elsewhere on the return, although each tax provision has its own calculation.

Example: A taxpayer who qualifies for the full $2,500 deduction and is in the 22% marginal federal bracket might reduce federal income tax by up to $550. That is $2,500 multiplied by 22%, not a $2,500 refund. Actual savings can differ because taxable income spans brackets, other provisions use AGI, and state rules vary. Compare the effect with the 2026 Federal Income Tax Calculator.

Who can claim student loan interest?

The taxpayer generally must be legally obligated to pay interest on a qualified student loan and must actually pay interest during the year. The taxpayer cannot use married filing separately and cannot be claimed as a dependent on someone else's return. If those threshold conditions are met, the expense and loan must still satisfy the qualified-loan rules.

The eligible student can be the taxpayer, the taxpayer's spouse or a person who was the taxpayer's dependent when the loan was taken out. Dependency is tested at the time the debt originated, subject to the Publication 970 rules. A later change in dependency or marital status does not automatically rewrite who originally borrowed the money.

What is a qualified student loan?

A qualified student loan is debt taken out solely to pay qualified higher-education expenses for an eligible student. The expenses must generally be paid or incurred within a reasonable period before or after the loan is taken out, and the education must be provided during an academic period for an eligible student.

An eligible student generally must be enrolled at least half time in a program leading to a degree, certificate or other recognized educational credential at an eligible educational institution. Qualified higher-education expenses generally include tuition and fees, books, supplies, equipment, and certain room-and-board costs, reduced by tax-free educational assistance.

Both federal and private debt can qualify. The tax rule focuses on the loan's purpose and terms, not the lender's marketing label. A personal loan used partly for tuition and partly for a car is not taken out solely for education expenses. A loan from a related person or a qualified employer plan is not a qualified student loan under the IRS rules.

Does refinancing preserve eligibility?

A refinanced student loan can remain qualified to the extent its proceeds are used solely to refinance qualified student-loan debt. If a borrower takes extra cash and uses it for another purpose, the new debt may fail the solely-for-education requirement or require careful allocation. Keep the old payoff statement, new loan agreement and disbursement trail.

Which interest payments count?

The deduction starts with interest actually paid during 2026, not merely interest that accrued. Required interest can qualify, and IRS Publication 970 explains that certain voluntary interest payments, capitalized interest and allocated loan-origination fees may also be treated as student loan interest when the requirements are met.

Capitalized interest is unpaid interest added to principal. As later payments retire that capitalized amount, a portion may count as deductible interest. Servicer records may not present every component the same way, so use the Form 1098-E instructions and the loan's payment history rather than estimating from the year-end principal balance.

Do not count principal, late fees that are not interest, collection costs or an amount paid with tax-free assistance when tax law prohibits a double benefit. If a student loan was discharged or a payment was made through an assistance program, confirm the tax treatment of that specific program.

Form 1098-E and the $600 reporting threshold

A loan servicer generally must send Form 1098-E when it receives $600 or more of student loan interest from a borrower during the year. The form typically arrives by January 31 after the tax year and shows reported interest in Box 1. Borrowers with multiple servicers may receive multiple forms.

The $600 rule is a reporting threshold, not a minimum deduction. If a borrower pays $425 of otherwise qualified interest and receives no Form 1098-E, the interest may still be deductible. Download an annual interest statement or payment history and keep it with the return. Conversely, receiving Form 1098-E does not guarantee eligibility: filing status, MAGI, dependency and loan-purpose rules still apply.

How the 2026 MAGI phaseout is calculated

First determine the tentative deduction: the smaller of $2,500 or qualified interest paid. If MAGI is within the phaseout range, multiply that tentative amount by a fraction. The numerator is MAGI minus the lower threshold; the denominator is $15,000 for eligible non-joint filers or $30,000 for joint filers. Subtract the resulting reduction from the tentative deduction, following IRS rounding instructions.

Single-filer example

A single filer pays $2,000 of qualified interest and has 2026 MAGI of $92,500. That is $7,500 above the $85,000 lower threshold, or halfway through the $15,000 phaseout range. The phaseout reduction is $1,000, leaving an estimated $1,000 deduction.

Married-filing-jointly example

A married couple filing jointly pays at least $2,500 of qualified interest and has MAGI of $190,000. That is $15,000 above the $175,000 lower threshold, or halfway through the $30,000 range. The estimated reduction is $1,250, leaving a $1,250 deduction. At $205,000 or more of MAGI, the deduction is zero.

Who gets the deduction when someone else pays?

Legal responsibility for the loan matters. If a parent pays a loan that is only in the adult child's name, the parent generally cannot claim the deduction because the parent is not obligated on the debt. Under IRS guidance, when the child is not the parent's dependent, the payment may be treated as a gift to the child followed by a payment from the child; the child may be able to deduct the interest if all requirements are met.

If a parent is the borrower or co-borrower and is legally obligated to pay, the result can differ. Do not allocate the same interest to two returns. Loan documents, dependency status and who made the payment should support the position taken.

Common double-benefit traps

• Do not deduct interest that was not actually paid during the year.
• Do not treat principal as interest simply because the total payment was large.
• Reduce qualified education expenses by tax-free scholarships, employer assistance and other tax-free benefits when required.
• Do not use the same expense to support incompatible education tax benefits.
• Do not assume a 1098-E proves the underlying loan was used solely for qualified expenses.

The student loan interest deduction is separate from the American Opportunity and Lifetime Learning credits, which generally concern current education expenses rather than interest. IRS Publication 970 coordinates these benefits and should be used when several appear on the same return.

How to claim the deduction for 2026

1. Collect every Form 1098-E and annual servicer statement.
2. Verify that each debt meets the qualified student loan tests.
3. Add eligible interest actually paid, including supportable amounts not reported because they were below $600.
4. Limit the tentative deduction to $2,500 per return.
5. Calculate 2026 MAGI and apply the appropriate filing-status phaseout.
6. Enter the result as the student loan interest adjustment on Schedule 1 of Form 1040, using the final 2026 instructions.

Use the Student Loan Payment Calculator to separate repayment planning from the tax calculation. The calculator estimates payoff and interest over time; a tax return uses interest actually paid during the calendar year.

Planning beyond the deduction

A tax deduction should not drive a borrower to keep expensive debt. Paying $1 of interest to save a fraction of a dollar in tax still costs money. Compare the loan's rate, emergency savings, employer match and other priorities. For new federal borrowing, see the 2026–27 federal student loan interest rates. Students evaluating aid before borrowing can also review the 2026–27 Pell Grant guide.

Borrowers close to an income threshold should not assume that lowering taxable income has the same effect as lowering MAGI for this deduction. Follow the specific MAGI worksheet and consider qualified professional help when the return includes foreign income exclusions, adoption benefits or other adjustments.
