Student Loan Interest Deduction 2026: Phase-Out Now $85K Single, $175K Joint

The IRS confirmed the student loan interest deduction 2026 stays capped at $2,500, with the modified adjusted gross income (MAGI) phase-out starting at $85,000 for single filers and $175,000 for joint filers. Borrowers earning above $100,000 single or $205,000 joint lose the write-off entirely. The deduction remains above-the-line, meaning you claim it on Schedule 1 of Form 1040 without itemizing. Your loan servicer will send Form 1098-E if you paid at least $600 in interest last year. Recent college grads managing first loan payments should map their MAGI now.

What changed in the student loan interest deduction 2026

The dollar cap did not move. The lesser of $2,500 or the actual interest paid is still the ceiling, matching a limit that has held since 2001. What did shift is the annual MAGI adjustment. Single, head-of-household, and qualifying surviving spouse filers now phase out between $85,000 and $100,000. Joint filers phase out between $175,000 and $205,000. Married-filing-separately taxpayers remain fully ineligible. The rules trace back to IRC Section 221 and Publication 970, both updated for the 2025 tax year returns filed in 2026.

How the MAGI phase-out actually works

The phase-out is linear, not a cliff. If a single filer reports MAGI of $92,500, they sit at the midpoint of the $85K-$100K band and can claim roughly half of their otherwise allowable interest. The IRS Student Loan Interest Deduction Worksheet in the Form 1040 Instructions runs the math. For joint filers at $190,000 MAGI, the same logic cuts the deduction in half. Once MAGI hits $100,000 single or $205,000 joint, the deduction hits zero. Early-career borrowers with signing bonuses or stock vesting should model this before December 31.

Why the 1098-E tax form matters this year

Loan servicers must issue Form 1098-E to every borrower who paid $600 or more in student loan interest during 2025. The form arrives by late January 2026, either by mail or through your servicer's online portal. Box 1 shows the total interest. You may still deduct interest below $600, but you have to pull the number from your servicer statements yourself. Federal loan servicers like MOHELA, Nelnet, and EdFinancial post the form under the tax documents tab. Private lenders such as SoFi and Earnest do the same.

Who benefits most from this above-the-line tax deduction

Above-the-line deductions reduce adjusted gross income directly, which in turn can unlock other credits tied to AGI thresholds, including the Saver's Credit and certain premium tax credit calculations. Recent grads in their first analyst, teaching, or engineering roles typically fall well under the $85,000 single threshold and can take the full $2,500 write-off. At a 22% federal marginal rate, that is $550 back. Households where one spouse earns high six figures should double-check joint MAGI, because the $175,000 joint start is not double the single figure and often trips up dual-income couples.

Common filing mistakes to avoid

Several errors keep surfacing across tax-prep filings. First, borrowers deduct principal payments; only interest counts. Second, filers forget that voluntary interest paid during grace periods and forbearance still qualifies. Third, refinanced loans stay eligible as long as the new loan meets the qualified education loan definition under IRC 221. Fourth, married couples file separately hoping to preserve the deduction, but MFS status disqualifies both spouses outright. Fifth, dependents claimed on a parent's return cannot claim the deduction themselves, even if they made every payment.

Key Takeaways

• The student loan interest deduction 2026 caps at $2,500 and remains above-the-line, so no itemizing required.
• MAGI phase-out runs $85,000 to $100,000 for single filers and $175,000 to $205,000 for joint filers.
• Form 1098-E arrives by late January if you paid $600 or more in interest during 2025.
• Married filing separately disqualifies both spouses entirely, no exceptions.
• Only interest counts, not principal, and refinanced loans still qualify if they meet IRC 221 rules.

What's Next

The 2025 tax return filing window opens in late January 2026, and the IRS typically publishes the final Form 1040 Instructions and updated Publication 970 in mid-January. Borrowers should log in to their servicer accounts by February 1 to grab Form 1098-E. Anyone approaching the phase-out band should run their numbers through the IRS Student Loan Interest Deduction Worksheet or a calculator like the one published by National Tax Tools before filing.
