The Tax Policy Center (a research group) says that about 47% of households in the U.S. will not pay federal income taxes for 2009.
The Associated Press reported the story today.
Last June, a senior fellow at the Tax Policy Center wrote an analysis titled: "Who Pays No Income Tax?" : www.taxpolicycenter.org/UploadedPDF/1001289_who_pays.pdf
Roberton Williams also wrote an OP-ED piece, published in the Washington Post - saying 45% of households will not owe federal income taxes in 2010: www.taxpolicycenter.org/publications/url.cfm
Williams writes that many will not owe because of earned income credits, the HOPE credit, and credits for retirement savings contributions.
