About 47 percent will pay no federal income taxes at all for 2009. Either their incomes were too low, or they qualified for enough credits, deductions and exemptions to eliminate their liability. That's according to projections by the Tax Policy Center, a Washington research organization.

In recent years, credits for low- and middle-income families have grown so much that a family of four making as much as $50,000 will owe no federal income tax for 2009, as long as there are two children younger than 17, according to a separate analysis by the consulting firm Deloitte Tax.

The bottom 40 percent, on average, make a profit from the federal income tax, meaning they get more money in tax credits than they would otherwise owe in taxes. For those people, the government sends them a payment.

That helps explain the country's aversion to taxes, said Clint Stretch, a tax policy expert Deloitte Tax. He said many people simply look at the difference between their gross pay and their take-home pay and blame the government for the disparity

"It's not uncommon for people to think that their Social Security taxes, their 401(k) contributions, their share of employer health premiums, all of that stuff in their mind gets lumped into income taxes," Stretch said.
