How much does the federal government take in through income tax? During fiscal year 2007 (Oct. 1, 2006, to Sept. 30, 2007) the IRS reported collecting a total of almost $2.4 trillion after refunds, with $248.6 billion of that coming from individual taxpayers.

As in recent years, about $350 billion in taxes due went uncollected, representing an annual phenomenon the IRS calls the "tax gap."

In processing more than 235 million individual and business tax returns, the IRS spent an average of 40 cents to collect each $100 of taxes, the lowest cost per $100 in seven years.

The IRS Takes and Gives Back: While it often seems like they are all about "take," the IRS paid out tax refunds totaling $248.6 billion to more than 114 individual tax return filers, and answered more than 33.2 million toll-free calls from taxpayers during 2007.
