Buoyed by a clear-cut election victory, US President George W. Bush is pledging to make permanent the sweeping tax cuts of his first term and to simplify the nation's tax laws.
The price tag on making the tax cuts permanent is more than US$1 trillion -- a daunting number in an age of record budget deficits.
At the same time, efforts to enact ambitious proposals to overhaul the tax system often fall victim to a ferocious assault from Washington lobbyists determined to protect special breaks for their clients.
While not discounting the challenges ahead, Bush's supporters are betting that the president will end up getting much of what he wants with the help of bigger Republican majorities in both the House of Representatives and the Senate.
"Tax reform is a politically dangerous road to travel with a lot of corpses," said Stephen Moore, head of the Club for Growth, which supports an aggressive tax-cutting agenda.
"But the president is very serious about this. He wants to make a major push for overhauling the tax system," Moore said.
Moore and others expect Bush's model will be Ronald Reagan's successful effort to enact the 1986 tax overhaul, one of the broadest rewrites of tax law in history. It dramatically lowered tax rates and paid for those reductions by eliminating or scaling back tax deductions.
So far, Bush has disclosed little about how he wants to simplify the current system, which he has called a "complicated mess."
He first stated his tax overhaul goal in his August acceptance speech at the Republican National Convention. He promised that if re-elected, he would create a bipartisan advisory panel to come up with a "simpler, fairer, pro-growth system."
The idea did not attract much attention during the campaign against Democratic Senator John Kerry. But last week, Bush put the idea front and center again, telling reporters at his first post-election news conference, "We must reform our complicated and outdated tax code."
Bush said any plan should be "revenue neutral," meaning the overall changes would not increase taxes or cut taxes. He also said the proposal should be viewed as fair without tax loopholes for special interests.
Bush indicated he favored protecting "certain incentives" such as deductions for mortgage interest rates and charitable contributions.
"It's going to take a lot of legwork to get something ready for a legislative package," Bush said.
He gave no hint about when he planned to appoint the members of his tax advisory group. The expectation is that none of the proposals will show up in the president's next budget, which goes to Congress in early February.
In August, Bush suggested that a proposed national sales tax was "an interesting idea that we ought to explore seriously." But the White House quickly backed away from the proposal, which Democrats contended would raise the cost of living for poor families while giving the wealthy a big tax break.
White House political adviser Karl Rove told NBC television's Meet the Press on Sunday that Bush "wants to look at all options."
Some House Republicans, angered by how long it takes people to fill out their tax returns each year, are pushing the idea of replacing the current income tax. Alternatives could include a national sales tax, some other form of consumption tax, or possibly a simplified "flat tax," which taxes all income at a single rate and gets rid of deductions.
