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.
But nationally, the tax code is still broadly progressive. The more your make, the more taxes you pay as a percentage of your income. According to new data from the IRS, people who make $1 million or more had an average tax rate of 20.4 percent in 2010. Tax filers who earned $30,000 to $50,000 paid an average rate of 4.8 percent, while those who made between $50,000 and $100,000 paid 7.7 percent.
