What Is the Student Loan Interest Deduction?
The student loan interest deduction allows a borrower to subtract up to $2,500 of interest paid on qualified education loans from taxable income each year. According to IRS Topic No. 456, the deduction equals the lesser of $2,500 or the amount of interest actually paid during the year, and it phases out at higher incomes. Because it is taken as an adjustment to income, often called an above-the-line deduction, a borrower claims it without itemizing, and it reduces adjusted gross income directly.
What Are the Income Limits?
The deduction phases out over a modified adjusted gross income (MAGI) range that the IRS sets annually. For returns covering tax year 2025, IRS Publication 970 states that the deduction is gradually reduced when MAGI falls between $85,000 and $100,000 for single filers, or between $170,000 and $200,000 on a joint return, and is unavailable once MAGI reaches $100,000 ($200,000 joint). Within the phaseout band, the allowable deduction shrinks proportionally as income rises. The IRS publishes the figure for each new tax year in Publication 970 and the Form 1040 instructions, so filers preparing a 2026 return locate that year's thresholds in the updated publication.
Which Loans and Borrowers Qualify?
Several conditions determine eligibility for the deduction:
- The loan was taken out solely to pay qualified higher education expenses, such as tuition, fees, room and board, books, and supplies, for the borrower, a spouse, or a dependent.
- The filer is legally obligated to pay the interest. A parent who repays a loan held only in a child's name is not the obligated party and does not claim the deduction.
- The filing status is not married filing separately.
- Neither the filer nor a spouse on a joint return can be claimed as a dependent on someone else's return.
Both federal and private education loans can qualify when they meet the definition of a qualified student loan. Loans from a relative or from an employer retirement plan do not qualify.
How Do Borrowers Claim the Deduction?
Loan servicers report interest received on Form 1098-E when a borrower pays $600 or more of interest in a year; borrowers who paid less can obtain the total from the servicer's records. The amount goes on Schedule 1 of Form 1040 as an adjustment to income. Interest that counts includes required interest payments, voluntary prepaid interest, and, in many cases, loan origination fees and capitalized interest as they are treated under IRS rules described in Publication 970. Payments applied entirely to principal generate no deductible interest for that period. Borrowers with loans at multiple servicers combine the interest totals from each Form 1098-E, since the $2,500 ceiling applies per return rather than per loan, and married couples filing jointly share a single $2,500 limit between them regardless of how many borrowers or loans appear in the household.
How Do the 2026 Repayment Changes Affect the Deduction?
Federal repayment rules changed on July 1, 2026, when the Repayment Assistance Plan (RAP) and a revised Standard Plan became the two options for new federal borrowers. The deduction itself was not changed by that law, but repayment plan design affects how much interest a borrower actually pays in a year, which in turn sets the deductible amount:
- Under RAP, unpaid monthly interest is waived rather than added to the balance, and payments are set at 1 to 10 percent of adjusted gross income. Only interest actually paid is deductible; waived interest is not.
- Under the revised Standard Plan, fixed payments over 10 to 25 years front-load interest in the early years, which typically produces larger deductible amounts early in repayment.
- New federal loans first disbursed for 2026-27 carry fixed rates of 6.52 percent for undergraduate Direct Loans, 8.07 percent for graduate Direct Loans, and 9.07 percent for PLUS loans.
How Does Employer Loan Assistance Interact With the Deduction?
Under Section 127 of the tax code, an employer with a written educational assistance plan can pay up to $5,250 per year toward an employee's education costs or student loan payments without the amount counting as taxable wages, a provision made permanent by 2025 legislation and indexed for inflation beginning in 2026, as described in the IRS FAQ on educational assistance programs. No double benefit is allowed: interest paid with excluded employer money cannot also be claimed as a student loan interest deduction. Interest the borrower pays with personal funds remains deductible under the normal rules.
Frequently Asked Questions About the Student Loan Interest Deduction
Is the deduction worth a full $2,500 refund?
No. A deduction reduces taxable income rather than tax owed. A borrower who deducts $2,500 while in the 22 percent bracket reduces federal tax by up to $550.
Can a borrower claim the deduction without itemizing?
Yes. It is an adjustment to income taken on Schedule 1, available alongside the standard deduction.
Do payments made during forbearance count?
Interest actually paid during any status counts. Months in which no interest is paid, including paused payments, generate no deductible amount.
Does refinancing end eligibility?
Interest on a refinanced loan remains deductible when the new loan pays off a qualified education loan and covers only qualified education expenses. Cash-out amounts used for other purposes are excluded.
