Flexible spending accounts (FSAs) are a widely used arrangement that allow employees to pay for qualified out-of-pocket health expenses with pre-tax dollars. The tax preference given to FSAs has been controversial and recent health care law (Patient Protection and Affordable Care Act and Health Care and Education Reconciliation Act) limits the tax exclusion to an inflation-adjusted value of $2,500 (2013 $s). The limit is estimated to increase federal payroll and income tax receipts by $13 billion between 2013 and 2019. But the welfare implications of this change are unclear.This paper uses a unique panel dataset to explore the demographic profile of households likely to be affected by the tax increase. We use a sample of 19,322 households observed over the period 1998-2008. The data include FSA expenditures, insurance claim information for covered medical and dental expenditures, and household demographic information. We explore patterns of FSA usage by income and health status.We find that households likely to be affected by the tax increase disproportionately tend to be households experiencing one or more chronic health conditions. The existence of chronic illness is associated with relatively high and persistent medical expenses and also with relatively older and wealthier households. We estimate an average tax increase of $101 in 2013 for 13.9 million households with an FSA.
