WASHINGTON (AP) — President Barack Obama is turning to his biggest television audience of the year to pitch tax increases on the wealthiest Americans and put the new Republican Congress in the position of defending top income earners over the middle class.

As Obama continues to signal what he will propose during Tuesday's State of the Union address, senior administration officials said during the weekend that he will call for raising the capital gains rate on top income earners and eliminating a tax break on inheritances. The revenue generated by those changes would fund new tax credits and other cost-saving measures for middle-class taxpayers, officials said.

Tax increases are rarely welcomed by congressional Republicans, who now hold majorities in the House and the Senate for the first time in Obama's presidency. Obama's tax proposals will likely be dismissed, if not outright ignored, by lawmakers outside the Democratic Party's liberal base.

"Are they going to agree on everything? Absolutely not. I think we should have a debate in this country between middle class economics and trickle-down economics and see if we can come to an agreement on the things we do agree on," White House senior adviser Dan Pfeiffer said Sunday on CBS's "Face the Nation." He said the theme of the speech would be "middle-class economics."

Rep. Adam Kinzinger, R-Ill., said he had heard all five of President Barack Obama's State of the Union addresses, which are filled with proposals both good and bad. But he said the president has fallen short by failing to establish close ties to Congress.

"He's never reached out to Congress and Democrats will tell you the same thing. You can't get your proposals done unless you're willing to have a relationship with an important branch of government," Kinzinger said on ABC's "This Week."

Obama also is expected to call for lawmakers to make community college free for many students, increase paid leave for workers and enact broad cybersecurity rules. Administration officials disclosed details on the tax proposals on the condition of anonymity because they were not authorized to discuss the proposals by name ahead of the president's speech.

The centerpiece of the president's tax proposal is an increase in the capital gains rate on couples making more than $500,000 per year to 28 percent, the same level as under President Ronald Reagan. The top capital gains rate has already been raised from 15 percent to 23.8 percent during Obama's presidency.

Obama also wants to close what the administration is calling the "trust fund loophole," a change that would require estates to pay capital gains taxes on securities at the time they're inherited. Officials said the overwhelming impact of the change would be on the top 1 percent of income earners.

While GOP leaders have said they share Obama's desire to reform the nation's complicated tax code, the party has long been opposed to many of the proposals the president will outline Tuesday. For example, most Republicans want to lower or eliminate the capital gains tax and similarly want to end taxes on estates, not expand them.

Administration officials pointed to a third proposal from the president as one they hope Republicans would support: a fee on the roughly 100 U.S. financial firms with assets of more than $50 billion. Officials said the fee is similar to a proposal from former Republican Rep. Dave Camp of Michigan, who led the tax-writing Ways and Means Committee. Camp's plan, however, was part of a larger proposal to lower the overall corporate income tax rate.

Raising the capital gains rate, ending the inheritance loophole and tacking a fee on financial firms would generate $320 billion in revenue over a decade, according to administration estimates. Obama wants to put the bulk of that money into a series of measures aimed at helping middle-class Americans. Among them:

—A credit of up to $500 for families in which both spouses work. The administration says 24 million couples would benefit from the proposal, which would apply to families with annual income up to $210,000.

—Expanding the child care tax credit to up to $3,000 per child under age 5. The administration says the proposal would help more than 5 million families with the cost of child care.

—Overhauling the education tax system by consolidating six provisions into two, a move that could cut taxes for 8.5 million families. Republicans have been open to the idea of consolidating education tax breaks.

Obama's call for higher taxes on the wealthy could further antagonize Republicans who are already angry with the president over his vows to veto several of the party's priorities, including legislation to approve construction of the Keystone XL oil pipeline, make changes to the president's signature health care legislation and block his executive actions on immigration.

Even before officials revealed Obama's tax proposals, Republicans were saying that his veto threats are a sign of a president who didn't get the message from voters who relegated his party to minority status in the November election. New Senate Majority Leader Mitch McConnell, R-Ky., said the president still has a chance to change his tone.

Beyond rolling out new proposals, Obama's address is also expected to focus on making the case to the public that recent economic gains represent a real and lasting recovery. The approach reflects the White House's belief that it has been too cautious in promoting economic gains out of fear of looking tone deaf to the continued struggles of many Americans.

Obama isn't expected to make any major foreign policy announcements.
