Yes, there are income restrictions. To claim the maximum deduction, a taxpayer must have modified adjusted gross income of $40,000 or less ($60,000 for married taxpayers filing jointly). The amount of the taxpayer's deduction is gradually reduced for taxpayers with modified adjusted gross income between $40,000 and $55,000 (between $60,000 and $75,000 for married taxpayers filing jointly). For example, for 1998, the maximum deduction a single taxpayer with modified adjusted gross income of $47,500 could take would be $500. Taxpayers with modified adjusted gross income above $55,000 ($75,000 for married taxpayers filing jointly) may not claim the student loan interest deduction. The modified adjusted gross income limitations are indexed for inflation after 2002.
