WASHINGTON (AP) - The House will miss the midnight Monday deadline lawmakers set for voting to avoid the "fiscal cliff."
House Republicans notified lawmakers that the chamber will vote Monday evening on other bills. They say that will be their only votes of the day.
President Barack Obama and Senate Republican leader Mitch McConnell said Monday they are near a deal to avoid wide-ranging tax increases and spending cuts — the fiscal cliff — that take effect with the new year.
Both men said they were still bargaining over whether — and how — to avoid $109 billion in cuts to defense and domestic programs that take effect on Wednesday.
It remained unclear whether the Senate would vote Monday.
Congress could pass later legislation retroactively blocking the tax hikes and spending cuts.
Earlier, Obama said an agreement to avoid the fiscal cliff appeared to be "in sight," but cautioned no deal had been reached yet and work continues.
Obama says this has been a "pressing issue on people's minds," and told an audience of middle-class taxpayers the deal would, among other things, extend unemployment benefits for Americans "who are still out there looking for a job."
He said it's unfortunate a broader "grand bargain" on tax-and-spend issues couldn't be reached, but that "with this Congress, it couldn't happen at that time."
Officials familiar with the negotiations say an agreement would raise tax rates on family income over $450,000 a year and increase the estate tax rate.
"It appears that an agreement is in sight," Obama said. "But it's not done."
Obama said that negotiations still needed to address the broad, mandatory spending cuts set to take place at the start of the new year. He said that any deal to avoid those cuts at the start of the new year would need to be "balanced."
With a midnight deadline rapidly approaching, both sides were at an impasse over whether to put off automatic, across-the-board spending cuts set to take effect on Jan. 1, and if so, how to pay for that. Democrats want to put off the cuts for one year and offset the so-called sequester with unspecified revenue.
Officials emphasized that negotiations were continuing and the emerging deal was not yet final. President Barack Obama was to speak about the status of the negotiations from the White House Monday afternoon.
The proposal in the works would raise the tax rates on family income over $450,000 from 35 percent to 39.6 percent, the same level as under former President Bill Clinton. Also, estates would be taxed at 40 percent after the first $5 million for an individual and $10 million for a couple, up from 35 percent to 40 percent.
Unemployment benefits would be extended for one year. Without the extension, 2 million people would lose benefits beginning in early January.
A Republican official familiar with the plans confirmed the details described to The Associated Press.
The officials requested anonymity in order to discuss the internal negotiations.
Unless an agreement is reached and approved by Congress by the start of New Year's Day, more than $500 billion in 2013 tax increases will begin to take effect and $109 billion will be carved from defense and domestic programs
Though the tax hikes and budget cuts would be felt gradually, economists warn that if allowed to fully take hold, their combined impact — the so-called fiscal cliff — would rekindle a recession.
Urgent talks were continuing Monday afternoon between the White House and congressional Republicans, with longtime negotiating partners Vice President Joe Biden and Senate Republican leader Mitch McConnell at the helm. Underscoring the flurry of activity, another GOP aide said the two men had conversations at 12:45 a.m. and 6:30 a.m. Monday.
An agreement on the proposed deal would also shield Medicare doctors from a 27 percent cut in fees and extend tax credits for research and development, as well as renewable energy.
The deal would also extend for five years a series of tax credits meant to lessen the financial burden on poorer and middle-class families, including one credit that helps people pay for college.
The deal would achieve about $600 billion in new revenue, the officials said.
Despite the movement, Senate Majority Leader Harry Reid warned that time was running out to finalize an agreement.
"Americans are still threatened with a tax hike in just a few hours," said Reid, D-Nev., as the Senate began an unusual New Year's Eve session.
Liberal Sen. Tom Harkin, D-Iowa, took to the Senate floor after Reid to warn Democratic bargainers against lowering levies on large inherited estates and raising the income threshold at which higher tax rates would kick in.
"No deal is better than a bad deal. And this look like a very bad deal the way this is shaping up," said Harkin.
Letting tax rates rise for couples with incomes of $450,000 a year is a concessions for Obama, who campaigned for re-election on a pledge to set the levels at $200,000 for individuals and $250,000 for couples. It also marked a significant concession by Republican leaders who pledged to continue the George W. Bush-era tax cuts for all income earners. .
The hope of the White House and lawmakers was to seal an agreement, enact it and send it to Obama for his signature before taxpayers felt the impact of higher income taxes or federal agencies began issuing furloughs or taking other steps required by spending cuts.
Regardless of the fate of the negotiations, it appeared all workers would experience a cut in their take-home pay with the expiration of a two-year cut in payroll taxes.
"This whole thing is a national embarrassment," Sen. Bob Corker, R-Tenn., said Monday on MSNBC, adding that any solution Congress would swallow at this late stage would be inconsequential. "We still haven't moved any closer to solving our nation's problems."
In a move that was sure to irritate Republicans, Reid was planning — absent a deal — to force a Senate vote Monday on Obama's campaign-season proposal to continue expiring tax cuts for all but those with income exceeding $200,000 for individuals and $250,000 for couples.
In one sign of movement on Sunday, Republicans dropped a demand to slow the growth of Social Security and other benefits by changing how those payments are increased each year to allow for inflation.
Obama had offered to include that change, despite opposition by many Democrats, as part of earlier, failed bargaining with House Speaker John Boehner, R-Ohio, over a larger deficit reduction agreement. But Democrats said they would never include the new inflation formula in the smaller deal now being sought to forestall wide-ranging tax boosts and budget cuts, and Republicans relented.
"It's just acknowledging the reality," Sen. Susan Collins, R-Maine, said of the GOP decision to drop the idea.
As the New Year's Eve deadline rapidly approached, Democrats and Republicans found themselves at odds over a host of issues, including taxing large inherited estates. Republicans wanted the tax left at its current 35 percent, with the first $5.1 million excluded, while Democrats wanted the rate increased to 45 percent with a smaller exclusion.
The two sides were also apart on how to keep the alternative minimum tax from raising the tax bills of nearly 30 million middle-income families and how to extend tax breaks for research by business and other activities.
Republicans were insisting that budget cuts be found to pay for some of the spending proposals Democrats were pushing.
These included proposals to erase scheduled defense and domestic cuts exceeding $200 billion over the next two years and to extend unemployment benefits. Republicans complained that in effect, Democrats would pay for that spending with the tax boosts on the wealthy.
"We can't use tax increases on anyone to pay for more spending," said Sen. Kay Bailey Hutchison, R-Texas.
