The maximum deductible interest on a qualified student loan is $2,500 per return. If you are a taxpayer whose return status is married filing jointly, you are allowed to deduct the full $2,500 only when your modified adjusted gross income (MAGI) is $100,000 or less. If your MAGI is more than $105,000, but less than $135,000, the amount of your student loan interest deduction is gradually reduced. The instructions for Form 1040 (PDF) show you how to compute the deduction. If your MAGI is $135,000 or more, you are not able to take any deduction.

For those whose filing status is single, head of household, or qualifying widow(er), the full $2,500 deduction is allowed for MAGI levels equal to or below $50,000. For MAGI between $50,000 and $65,000, the deduction amount is gradually reduced. The Form 1040 Instructions show you how to compute the deduction. If your MAGI amount is $65,000 or more, there is no deduction.

There is no deduction if you file as married filing separately, if you are claimed as a dependent, or if the loan is from a related party or a qualified employer plan.
