Twenty-six Fortune 500 corporations paid no U.S. federal income tax between 2008 and 2011, despite bringing in billions in profits and receiving huge subsidies from the federal government, according to a report released this week by the nonprofit advocacy group Citizens for Tax Justice, or CTJ.

Last year alone, 24 of the 30 multinational companies analyzed by CTJ paid effective tax rates under 4 percent, far below the federal statutory rate of 35 percent. Overall, the effective tax rate paid by the companies in question during the four-year period was -3.1 percent on a combined $205 billion in U.S. profits.

The companies analyzed by CTJ include some of the biggest corporate names in the U.S., most of which have contributed hundreds of thousands of dollars to the elected officials responsible for the tax policies allowing them to pay those small tax rates on their profits.

Following is a look at the five most profitable companies on the CTJ list and the top five federal political candidates or incumbents who have benefited from the backing of each of the companies' employees and political action committees during the 2011-2012 election cycle. The contribution figures are drawn from publicly available data at the Center for Responsive Politics' OpenSecrets.org.
