Tax subsidies for private health insurance - july 2009 update.

Tax subsides for employer-sponsored health insurance are the largest subsidy for private health insurance and support key mechanisms of the U.S. insurance system, but they overwhelmingly benefit high-wage employees. When employers purchase or provide insurance for their employees, their contributions to the premium are excluded from income and payroll taxes. This tax exclusion provided more than $100 billion in income and payroll tax subsidies in 2002. High-income workers benefit more from these subsidies than those with lower incomes because of their higher marginal tax rate. Applying the tax exclusion in their respective tax brackets means high-income families (those earning more than $200,000) receive a subsidy worth one-third of the premium, while the lowest income families receive a subsidy worth just 10 percent. Despite these issues, ESI is a successful mechanism in many ways, covering a significant majority of Americans and providing a good pooling mechanism.
