Similar to federal student loans, RISLA uses the federal poverty guidelines to determine if a borrower qualifies for IBR. Each year, the U.S. Department of Health and Human Services calculates an updated federal poverty guideline for each State by family size. Recent and historic poverty guidelines tables can be found here.
Family size is strictly determined by whatever family size is indicated on an IBR applicant's prior year tax returns. If married and filing separately or joining custody of children captures family size differently than the current living situation, please note that the family size is derived solely from tax returns, and word-of-mouth variations are unacceptable. If one or more children are born, increasing the family size since the prior year's tax returns, providing one or more birth certificates is acceptable to show the increase in family size. If the IBR applicant does not report taxes, a family size of 1 is used for the calculations. Family size is considered independently for both the borrower and the cosigner.
