7% comes from Excise Tax

4% is other sources

Notes:

In 2008 the federal government collected $2.5 trillion, an amount equal to 17.7 percent of GDP. Federal revenue has ranged from 14.4 to 20.9 percent of GDP over the past five decades, averaging 18.2 percent.

• Payroll taxes swelled following the creation of Medicare in 1965. Taxes for Medicare, combined with periodic increases in Social Security taxes, caused payroll tax revenue to grow from 1.6 percent of GDP in 1950 to more than 6 percent since 1990. Payroll taxes also include railroad retirement, unemployment insurance, and federal workers' pension contributions.
• Revenue from the corporate income tax fell from between 5 and 6 percent of GDP in the early 1950s to 2.1 percent of GDP in 2008.
• Excise taxes fell steadily throughout the same period, from nearly 3 percent of GDP in 1950 to 0.5 percent in recent years.
• The remaining sources of revenue have fluctuated less, together claiming between 0.5 and 1.0 percent of GDP since 1950 and standing near the bottom of that range in 2008.
