During his 2012 presidential campaign, Romney said he would seek income tax law reforms that he said would help lower federal deficits and would stimulate economic growth. Among the series of tax changes he proposed were: reducing individual income tax rates across the board by 20 percent, maintaining the Bush administration-era tax rate of 15 percent on investment income from dividends and capital gains (and eliminating this tax entirely for those with annual incomes less than $200,000), cutting the top tax rate on corporations from 35 percent to 25 percent, and eliminating the estate tax and the alternative minimum tax. He promised that the loss of government revenue from these tax cuts would be offset by closing loopholes and reining in tax deductions and credits available to taxpayers with the highest incomes, so that his tax plan would not raise federal deficits. Non-partisan analyses of Romney's tax plan estimated that it could have added more than $3 trillion to the federal deficit, and would have favored the highest-earning Americans, possibly raising annual taxes on middle-class earners by as much as $2,000. Romney and supporters of his tax plan said that such analyses were unreliable because they were based on assumptions about specific measures that were not detailed in the plan and because they had not adequately accounted for the positive effects on economic growth that Romney said his plan would generate. And that lower tax rates would lower rates of Tax evasion.
