In his campaign for the Republican presidential nomination, Mitt Romney has proposed permanently extending the 2001–03 tax cuts, further cutting individual income tax rates, broadening the tax base by reducing tax preferences, eliminating taxation of investment income of most individual taxpayers, reducing the corporate income tax, eliminating the estate tax, and repealing the alternative minimum tax and the taxes enacted in 2010’s health reform legislation. The Tax Policy Center (TPC) has completed a preliminary analysis of the Romney plan, based on information posted on the campaign website and e-mail exchanges with campaign policy advisers. Because we have received no details on proposals to reduce tax preferences, the TPC analysis does not include those proposals.
