A letter report issued by the Government Accountability Office with an abstract that begins "Multiple Title IV programs and tax expenditures provided substantial aid to populations across income levels. In 2009, 12.8 million students received Title IV aid, and approximately 18-million tax filers claimed a higher education tax benefit for current expenses. Recent increases in both programs from 2008 to 2009 may be because of enrollment increases and legislative actions, among other factors. Title IV grants tend to benefit students and families with incomes below the national median (about $52,000 from 2006–2010), while loans and work-study serve these students and those with family incomes above the median. Most tax benefits from the tuition and fees deduction and the parental exemption for dependent students went to households with incomes above $60,000, whereas the majority of benefits from the other higher education tax expenditures in GAO’s review—such as the American opportunity credit—went to households with lower incomes."
