Quick Summary:
- Above-the-Line Tax Savings: You can deduct up to $2,500 in student loan interest paid during the tax year directly from your income without needing to itemize deductions.
- Core IRS Eligibility: You must be legally obligated to pay the loan, your filing status cannot be Married Filing Separately, and you cannot be claimed as a dependent on someone else’s return.
- Income Phase-Out Thresholds: The deduction phases out for single filers with Modified Adjusted Gross Income (MAGI) between $80,000 and $95,000 ($165,000 to $195,000 for married couples filing jointly).
- Form 1098-E: Lenders send Form 1098-E if you paid $600 or more in interest; however, interest paid below $600 is still fully deductible.

For thousands of residents across Greater St. Louis—from recent graduates starting careers in Downtown St. Louis to working professionals in Clayton and parents financing higher education in West County—student loan debt is a significant monthly expense.
Fortunately, the tax code provides targeted relief for student loan borrowers. The Student Loan Interest Deduction allows eligible taxpayers to reduce their federal taxable income by writing off interest paid on qualified higher education loans.
Best of all, because this is an above-the-line deduction (claimed directly on Schedule 1 of Form 1040), you can take advantage of it even if you claim the standard deduction.
To help local taxpayers maximize their return, STL Tax breaks down the rules, income limits, and filing steps for deducting student loan interest.
1. How Much Student Loan Interest Can You Deduct?
The IRS allows eligible borrowers to deduct up to $2,500 (or the actual amount of interest paid during the tax year, whichever is less) per tax return.
What Interest Qualifies?
- Required monthly interest payments on federal and private student loans.
- Voluntary prepaid interest or extra principal/interest payments made during the year.
- Capitalized interest (interest added to your principal loan balance during forbearance or deferment).
2. Who Qualifies for the Student Loan Interest Deduction?
To claim the deduction on your federal and Missouri tax returns, you must satisfy all of the following IRS criteria:
- Legal Obligation: You paid interest on a qualified student loan taken out solely to pay for qualified higher education expenses for yourself, your spouse, or your dependent.
- Filing Status: Your tax filing status is Single, Head of Household, Qualifying Surviving Spouse, or Married Filing Jointly. Taxpayers who file as Married Filing Separately are ineligible.
- Not a Dependent: You cannot be claimed as a dependent on another taxpayer’s return (e.g., a college student claimed by their parents cannot claim the deduction on their own return).
- Income Limits: Your Modified Adjusted Gross Income (MAGI) falls below the annual IRS phase-out limits.
3. Income Phase-Out Limits (MAGI Thresholds)
The student loan interest deduction is subject to income phase-outs. If your MAGI exceeds the lower limit, your deduction is reduced proportionally until it is completely eliminated at the upper limit.
4. Understanding Form 1098-E
In January or early February, your loan servicer (such as Nelnet, MOHELA, Aidvantage, or private lenders) will provide Form 1098-E (Student Loan Interest Statement) if you paid $600 or more in interest during the tax year.
Important 1098-E Tips:
- Interest Under $600 Is Still Deductible: If you paid less than $600 in interest, your loan servicer is not required to issue Form 1098-E, but you can still legally deduct the interest. Log into your online loan servicer dashboard to view your annual payment summary.
- Multiple Loan Servicers: If you consolidated loans or have multiple servicer accounts, gather Form 1098-E from each servicer to calculate your combined interest total up to the $2,500 limit.
5. Parent Loans & Refinanced Loans
- Parent PLUS Loans: Parents who took out Parent PLUS loans to fund their child’s education can claim the student loan interest deduction on their own return, provided the parent meets MAGI limits and files jointly or single.
- Refinanced Student Loans: Interest paid on refinanced or consolidated student loans remains deductible, provided the original loan was used exclusively for qualified higher education expenses.
