House Speaker John Boehner on Tuesday offered a fall-back option to avert the looming fiscal crisis, pitching a proposal to rank-and-file Republicans that would prevent a tax hike for most Americans. 

The move comes amid accelerating talks with President Obama, but is being positioned as a "Plan B" in case those talks fail to yield a compromise before a Jan. 1 deadline -- that's when taxes are set to rise on everyone, followed by a wave of spending cuts. 

"Every income tax filer in America is going to pay higher rates come Jan. 1 unless Congress acts," Boehner said.
