The Senate will not vote on extending any of the Bush-era tax cuts until after the November election.
"Democrats believe we must permanently extend tax cuts for the middle-class before they expire at the end of the year, and we will," Jim Manley, a spokesman for Senate Majority Leader Harry Reid said in an e-mail, Reuters reported.
"Unfortunately, to this point we have received no cooperation from Republicans to do so."
The Senate will address the issue after its recess for the November elections, Manley said.
President Barack Obama and most Democrats want to extend the tax cuts for the first $200,000 of personal income and $250,000 of household income, while Republicans and some Democrats want the tax cuts extended for all.
