(CNN) - Rick Perry gave a preview of his tax plan to the Western Leadership Conference in Las Vegas Wednesday ahead of its official unveiling next week.
Perry said his plan will center on a complete overhaul of the tax code - a move he says will create jobs and jumpstart economic growth.
"It starts with scrapping the three million words of the current tax code, and starting over with something much simpler: a flat tax," Perry said.
In his remarks, Perry took a dig a Treasury Secretary Tim Geithner, who came under fire in 2009 for failing to pay self-employment taxes while working for the International Monetary Fund.
"I want to make the tax code so simple that even Timothy Geithner can file his taxes on time," Perry said.
Perry's speech did not elaborate on the specifics of the proposed flat tax, leaving that instead to his speech next week in South Carolina.
But he did offer some broad strokes about other elements of his plan, including an initiative to increase American energy production, and cutting down on Congressional earmarks.
"But let me be even more clear: my plan ends earmarks for good," Perry said. "It's time to bring tough medicine to Washington. No longer will policy be set by K Street, it will be dictated by Main Street."
Perry also touched on a notion that has been popular on the GOP campaign trail: cutting back on government regulations.
"We will reverse course on the heavy hand of regulation, discarding Dodd-Frank and any other regulations that advance a political agenda at the expense of jobs and investment on Main Street," Perry said. "It is time to let America be America again. To return freedom to the people. To stand on our founding principles and reject the cynical politics of the Nanny State."
