Sets the annual repayment obligation for borrowers at an amount equal to 15% of the excess of their taxable income over the sum of: (1) an exemption amount equal to 150% of the federal poverty level for their household; and (2) the lesser of $3,000 or specified income other than wages, salaries, tips and other employee compensation.
