According to David Callahan, who heads a think tank called DEMOS, the government only collects about 85 percent of the money that it is owed. And what happens with that other 15 percent?

“Goes into the pockets of the tax cheaters, and the rest of us help subsidize them by paying higher taxes,” said Callahan.

There’s a lot to subsidize, he says The most recent IRS estimate shows a $385 billion shortfall in revenue, mostly from under-reported income.
