47% of Households Have on Federal Income Tax Burden

When considering federal income taxes in combination with payroll taxes, the percent of households with a net liability of zero or less is estimated to be 24% this year, according to the Tax Policy Center's estimates.

A key reason why there is a zero-liability group at all is because the U.S. tax system is progressive. Those who bring in more money pay more than those lower down the income scale to support government functions such as national defense and social safety nets like Medicaid for those in need. That progressivity can be dialed up or down.
