Under current law, the top capital gains tax rate would rise to 20 percent automatically at the end of the year if the cuts enacted during George W. Bush’s White House tenure were allowed to expire.
The tax on dividends would also rise. The estate tax would be 55 percent on estates after allowance for a $1 million exemption.
As the talks progress, Republicans across the party’s spectrum are eager to turn public attention toward spending cuts, rather than remain bogged down in a politically debilitating debate about tax increases.
‘‘Our problem isn’t that we tax too little. It’s that we spend too much! We must have serious spending cuts for a debt ceiling increase,’’ tweeted Rep. Tom Price., R-Ga.
That was a reference to the third ingredient under negotiation as part of deal to prevent the economy from reaching the fiscal cliff — an increase in the government’s borrowing authority.
After a brush with the first-ever default by the Treasury in 2011, Obama is demanding that any fiscal cliff compromise give him authority to raise the current $16.4 trillion cap without a prior vote by Congress. Officials say that Boehner’s most recent proposal would grant an increase equal to the size of any spending cuts, roughly $1 trillion under his own recommendations.
The speaker made his offer to Obama late last week, dropping his blanket opposition to the president’s call for an increase in the tax rate paid on upper incomes. Obama’s agreement to reduce his demand so it would affect incomes over $400,000 left the two sides closer, but short of agreement.
As part of the change, Obama is now seeking $1.2 trillion in additional revenue, down from $1.4 trillion that was in an offer he made several days ago.
Officials have said Boehner offered a total of $1 trillion in higher revenue, less than half of which would come this year, and the balance in 2013 as part of a bill to overhaul the tax code.
Some of the increased revenue to be provided immediately would come from setting the tax rate on income over $1 million at 39.5 percent, up from the current 35 percent. The balance would come from higher taxes on capital gains, dividends and other provisions.
The proposal to scale back cost-of-living increases is a regular at deficit reduction talks.
Obama tentatively agreed to back it more than a year ago in talks with Boehner that eventually collapsed, although he sought steps to shelter the lowest-income beneficiaries from its effects.
Democrats have said they would object much more strongly if the president would to accept a plan to raise the Medicare eligibility age from 65 to 67. He was ready to embrace that proposal in the earlier round of talks, but he would face opposition from congressional Democrats and the AARP as well as other groups in the current political climate.
The new inflation adjustment would create government savings of an estimated $168 billion over a decade, according to a recent estimate by the Congressional Budget Office. It also would raise tax revenue by $54 billion by affecting the adjustment in income tax brackets that occurs annually to take inflation into account, CBO said.
