Student loans: the interest deduction, and forgiveness is taxable again
What the interest deduction is worth and where it fades out, why a discharge after 2025 can create a tax bill, and which forgiveness routes stay tax free.
Quick answers
- Do I have to itemize to deduct student loan interest?
- No. It comes off income before the standard deduction, so you can take it and still take the standard deduction. It does fade out as income rises and it is not available to married filing separately.
- Is forgiven student debt taxable?
- Often, but not always. A temporary rule kept certain discharges out of income through the end of 2025, and Public Service Loan Forgiveness, along with discharge for the death or total and permanent disability of the student, stays excluded.
- What is a 1099-C and what do I do with it?
- It is the notice a lender sends after canceling a debt, showing the amount and the date. Report the canceled amount unless an exception applies, and keep the paperwork showing which exception you relied on.
Student loan interest comes off your income whether or not you itemize, up to a cap that fades out as income rises. Forgiveness is the harder half: a temporary rule kept certain discharges out of income through the end of 2025, and it has run out.
What changed for 2026
The American Rescue Plan Act changed how certain student loan discharges were treated, covering discharges after the end of 2020 and before the start of 2026. The last day inside that window was December 31, 2025.
A discharge after it is generally back under the ordinary rule, which is that canceled debt is income in the year it is canceled. The word doing the work in the old rule is "certain": it never covered every kind of forgiveness, so a borrower discharged during the window should still check which route theirs came through.
The interest deduction
What you deduct is whatever you genuinely paid in interest over the year, stopping at $2,500. Pay less than that and you deduct the smaller figure; pay more and the cap is what you get. It comes off income before the standard deduction rather than as an itemized deduction, so you take it and take the standard deduction as well. The IRS sets out the full list of conditions in Topic no. 456. Deductions and credits covers why that placement matters less than a credit of the same size would.
Where it fades out
The deduction shrinks across a band of modified adjusted gross income and then stops.
| Student loan interest deduction phase-out begins, single/HOH | $85,000 | Publication 970, Student Loan Interest Deduction |
|---|---|---|
| Student loan interest deduction phase-out ends, single/HOH | $100,000 | Publication 970, Student Loan Interest Deduction |
| Student loan interest deduction phase-out begins, married filing jointly | $170,000 | Publication 970, Student Loan Interest Deduction |
| Student loan interest deduction phase-out ends, married filing jointly | $200,000 | Publication 970, Student Loan Interest Deduction |
Inside the band you get a reduced deduction rather than none, so a raise part-way through the range costs part of it rather than all of it.
Who cannot take it, and what counts as a loan
Three groups are out regardless of income. Anyone whose filing status is married filing separately; anyone who can be claimed as a dependent on someone else's return; and anyone who was not legally obligated to pay the interest. That last one catches parents quietly paying down a loan that is in their child's name, because the obligation is the child's. Filing status covers the separate-return trade-off more generally.
The loan itself has to qualify too. It must have been taken out solely to pay qualified education expenses, for a student enrolled at least half time at an eligible institution, and it cannot come from a related person or from a qualified employer plan.
Forgiveness: the general rule
If a debt is canceled, forgiven or discharged for less than what you owed, the canceled amount is generally taxable. After a cancellation the lender may send Form 1099-C showing the amount canceled and the date, and the IRS receives a copy.
Forgiveness that stays tax free
Several routes sit outside the general rule, and they are separate from each other.
Discharge on the death or total and permanent disability of the student is listed as an exception on its face. Publication 970 carries a second, broader exclusion for profession-based cancellation. Broadly, the loan has to come from a qualifying lender, and the arrangement has to require the borrower to work for a period in a specified profession for a government body or a tax-exempt organization, or under the direction of one, in a place or a line of work that is short of people. It has a limit worth reading twice: it does not reach a loan canceled because of work you did for the school that lent you the money, or for whoever provided the funds.
Public Service Loan Forgiveness is a different program again, run by the Department of Education, and its Public Service Loan Forgiveness page sets out the qualifying conditions. A balance forgiven under it is not taxable income. That is the same profession-based logic as the exclusion above: the forgiveness is earned by working the required period for a government body or a qualifying non-profit.
Separately, repayment assistance under the National Health Service Corps Loan Repayment Program, and under state programs aimed at getting health services into underserved areas, is not income to the person who receives it.
Planning for a forgiveness year, and what to keep
A large discharge lands in one year's income all at once, and nothing was withheld against it. The tax on it is simply due at filing, which is how a year that felt like relief produces a balance nobody budgeted for.
There are two answers, and they are ordinary. Send estimated payments during the year the discharge happens, which quarterly estimates sets out, or arrange to pay the balance afterwards, which you owe more than you can pay right now covers. Keep the lender's interest statement, the discharge letter, any Form 1099-C, and the paperwork naming the program the forgiveness came under, because the exception you rely on is the thing you will be asked to show.
Employer help with loan payments
An employer may pay toward an employee's education costs under an educational assistance program, and some employers use one to make payments against student loans. The rules run through the employer's plan rather than your return, so ask what the plan covers and how the payments will be reported before counting on the treatment.
