K-12 Tax & Spending Climate: 47% will pay no federal income tax

Jeanne Sahadi:

An increasing number of households end up owing nothing in major federal taxes, but the situation may not be sustainable over the long run.
Most people think they pay too much to Uncle Sam, but for some people it simply is not true.
In 2009, roughly 47% of households, or 71 million, will not owe any federal income tax, according to estimates by the nonpartisan Tax Policy Center.
Some in that group will even get additional money from the government because they qualify for refundable tax breaks.
The ranks of those whose major federal tax burdens net out at zero — or less — is on the rise. The center’s original 2009 estimate was 38%. That was before enactment in February of the $787 billion economic recovery package, which included a host of new or expanded tax breaks.
The issue doesn’t get a lot of attention even as lawmakers debate how to pay for policy initiatives like health reform, whether to extend the Bush tax cuts and how to reduce the deficit.
