Updated October 24, 2026. Quick answer: Tax Topic 456 is the IRS page on the student loan interest deduction. It says you may deduct the lesser of $2,500 or the interest you actually paid during the year. It is an adjustment to income, so itemizing is not required, and the deduction phases out as modified adjusted gross income rises.
Quick reference
| Item | What the IRS topic says |
|---|---|
| Amount | “You may deduct the lesser of $2,500 or the amount of interest you actually paid during the year.” |

| Filing status | “Your filing status isn’t married filing separately” |
| Income limit | “The deduction is gradually reduced and eventually eliminated by phaseout when your modified adjusted gross income (MAGI) amount reaches the annual limit for your filing status.” |
| Form from the lender | “If you paid $600 or more of interest on a qualified student loan during the year, you should receive a Form 1098-E, Student Loan Interest Statement” |
What the deduction is
The topic starts with a definition. It says “Student loan interest is interest you paid during the year on a qualified student loan.” It adds that the term “includes both required and voluntarily prepaid interest payments.”
On the amount, the topic says “You may deduct the lesser of $2,500 or the amount of interest you actually paid during the year.” It describes how income affects the result: “The deduction is gradually reduced and eventually eliminated by phaseout when your modified adjusted gross income (MAGI) amount reaches the annual limit for your filing status.”
Who can claim it
The topic lists conditions and says “You can claim the deduction if all of the following apply:” Two of them are “You’re legally obligated to pay interest on a qualified student loan” and “Your filing status isn’t married filing separately”.
Another condition covers dependents. The topic says “Neither you nor your spouse, if filing jointly, were claimed as dependents on someone else’s return.” It also says the income test is “Your MAGI is less than a specified amount which is set annually”.
What makes a loan qualified
The topic says “A qualified student loan is a loan you took out solely to pay qualified higher education expenses that were:” The expenses must be “For you, your spouse, or a person who was your dependent when you took out the loan” and “Paid or incurred within a reasonable period of time before or after you took out the loan.”
For paperwork, the topic says “If you paid $600 or more of interest on a qualified student loan during the year, you should receive a Form 1098-E, Student Loan Interest Statement from the entity to which you paid the student loan interest.” Our page on Form 1098-E boxes 1 and 2 explains that form. The topic points to Publication 970 for the worksheet and the MAGI details.

Common mistakes
- Thinking itemizing is required. The topic says “so you don’t need to itemize your deductions.”
- Assuming the cap is the interest total. The topic says “the lesser of $2,500 or the amount of interest you actually paid during the year”
- Filing separately and still claiming it. The topic lists “Your filing status isn’t married filing separately”
- Expecting a Form 1098-E for any amount. The topic ties it to “$600 or more of interest”
- Treating any loan as qualifying. The topic says the loan was taken out “solely to pay qualified higher education expenses”
