US House Speaker John Boehner tabled a plan to avert the fiscal cliff that left out tax increases for the wealthy and was rejected within an hour by the White House.
The proposal also highlights divisions among factions of the Republican Party.
Mr Boehner's plan partly entails targeting $US800 billion in revenue over a decade from overhauling the tax code, closing loopholes and deductions.
Republican Senator Jim DeMint of South Carolina was one of the loudest dissenters.
"Speaker Boehner's $800 billion tax hike will destroy American jobs and allow politicians in Washington to spend even more," Mr DeMint says in a statement.
The comments may signal a repeat of the tactics of the so-called Tea Party faction within the GOP that stalled talks on lifting the federal debt ceiling last year and ultimately led to a credit rating downgrade.
The schism could be overstated, though Reuters reports the Republican leadership is trying to bring the Tea Party into line, removing what it called Tea Party stalwarts Tim Huelskamp and Justin Amash from the budget committee. Mr Huelskamp reportedly called it "a vindictive move".
Conservative think tanks also balked at the proposal, which the Heritage Foundation called "utterly unacceptable".
The deadline for averting the fiscal cliff, some $US607 billion of tax increases and spending cuts that kick in on January 1, is edging closer.
Allowing the automatic cuts and tax hikes risks plunging the world's biggest economy back into recession and driving the jobless rate, now 7.9%, sharply higher through 2013, economists say.
President Barack Obama called Mr Boehner's plan, which includes $US2.2 trillion in new revenue and spending cuts, "out of balance" in an interview with Bloomberg TV.
Yet it may yet signal progress as Mr Obama says he is willing to accept cuts to entitlements and realises he will not get all that he wants in negotiations. It is now down to the White House to counter-offer.
