Share of U.S. Corporate Income and Taxes by Size

February 18, 2014

In 2010, U.S. corporations paid about $223 billion in income taxes on slightly more than $1 trillion in taxable income. However, the vast majority of this income and taxes is attributable to the roughly 2,700 corporations with assets above $2.5 billion. Indeed, these corporations earned 77 percent of total corporate taxable income in 2010 and account for 69 percent of all corporate income taxes paid in the United States. Meanwhile, mid-size companies with assets between $500 million and $2.5 billion in assets earned 11 percent of corporate income and paid 14 percent of corporate income taxes.
