Starting in 2026, borrowers who paid interest on a qualified student loan can reduce their taxable income by as much as $2,500. The benefit is an above-the-line adjustment, meaning it is taken before the standard deduction and does not require itemizing. For many taxpayers the deduction translates into a $300-to-$550 tax saving, depending on the marginal tax bracket. The rule is especially relevant this year because it is the first full calendar year that borrowers who were in the SAVE forbearance see interest accrue again at the normal rate.
Eligibility requirements and what counts as deductible interest
To qualify, you must satisfy four conditions outlined in IRS Publication 970. First, you must have actually paid interest on a qualified student loan during the tax year. The loan can be federal or private, but it must have been taken out solely for qualified education expenses such as tuition, fees, room and board, books, supplies, or transportation for yourself, a spouse, or a dependent who was enrolled at least half-time. Second, you must be legally obligated to repay the loan; co-signers meet this test. Third, your modified adjusted gross income (MAGI) must fall below the phase-out thresholds described later. Fourth, you cannot be claimed as a dependent on someone else’s return.
The IRS permits several types of interest to be included: regular interest charged by the lender, loan-origination fees that are amortized over the life of the loan, capitalized interest (unpaid interest added to principal), and interest on refinanced or consolidated loans provided the new loan only refinances qualified student loans. What does not qualify includes interest that the Department of Education waived under the Repayment Assistance Plan (RAP), interest covered by an employer’s tax-free repayment program, and any portion of a loan that paid for expenses already covered by tax-free scholarships or 529 distributions.
Income thresholds and the phase-out mechanism
For 2026 the phase-out ranges are set by Rev. Proc. 2025-32. A single filer loses the full deduction once MAGI exceeds $100,000; the deduction tapers linearly between $85,000 and $100,000. Married couples filing jointly face a ceiling of $200,000, with a phase-out band from $175,000 to $200,000. Those filing as head of household follow the single-filers’ limits. Taxpayers filing separately receive no deduction at any income level, which also eliminates several other credits, so it is usually advisable to run both filing scenarios before deciding. Inside the band, the allowable amount is reduced proportionally – for example, a single filer with $92,500 MAGI is halfway through the $85,000-$100,000 range and can claim only $1,250.
How to claim the deduction and estimate your savings
Each loan servicer that collected $600 or more in interest will issue a Form 1098-E by January 31. If you have multiple servicers, you will receive a separate form from each; if total interest from a servicer is below $600 you can still claim the amount by retrieving it from the online portal or requesting a statement. On your 2026 return, total deductible interest is entered on Schedule 1, line 21 of Form 1040 (the “Adjustments to Income” section). No attachment of the 1098-E is required, but keep the form for your records. Tax-software programs automatically apply the phase-out calculation.
The actual tax benefit equals the deducted amount multiplied by your marginal tax rate. A single borrower earning $50,000 who paid the full $2,500 would be in the 12 % bracket, saving $300. Someone in the 22 % bracket would see a $550 reduction. If you paid less than $2,500, you deduct the amount you actually paid; $1,200 at a 12 % rate reduces tax by $144. Remember that a deduction lowers taxable income, not the tax dollar-for-dollar, unlike a credit.
State tax treatment usually mirrors the federal adjustment because most states start from federal AGI. California conforms fully, with a narrow exception for military spouses in community-property states. If you missed the deduction in a prior year, you can file Form 1040-X within three years of the original filing date to claim the missed amount.
