The IRS is responsible for collecting taxes and the administration of the Internal Revenue Code. It has also overseen various benefit programs. The first income tax was assessed in 1862 to raise funds for the American Civil War, with a rate of 3%. Today the IRS collects over $2.4 trillion each tax year. It processes around 234 million tax returns annually.
The IRS estimated that 24% of all Earned Income Tax Credit payments in fiscal year 2013 (roughly $14.5 billion) were mistakenly paid. Although some errors were unintentional, resulting from the credit's qualification complexity, others involved filers who intentionally disregarded legal qualifications, the IRS says.
