The top 1 percent of income earners would be the biggest winners under Republicans' plans to rewrite the tax code, according to a new analysis, while some moderate-income people would face tax increases. About 30 percent of those earning between $50,000 and $150,000, and 60 percent of those taking home between $150,000 and $300,000, would pay more under the Republican plan, according to the nonpartisan Tax Policy Center.
