National Press Building in Washington, D.C. In 2015, the organization moved to its current location on G Street. Goals and principles The Tax Foundation states that its research is guided by what it calls the principles of sound tax policy: simplicity, transparency, neutrality, and stability. Tax Foundation research is generally critical of tax increases, high business taxes, excise taxes, tax preferences for the housing industry, and use of tax credits, which the Foundation views as "picking winners and losers". The Foundation has spoken favorably of efforts to balance the federal budget with tax reform and significant spending cuts, such as the Bowles-Simpson plan, the Ryan Plan, and the Wyden-Coats plan. Organizational overview Ideology The Tax Foundation describes itself as an "independent tax policy research organization". It is cited in the media as a nonpartisan or bipartisan organization, and is also described as business-friendly, conservative, and center-right. Board of directors As of 2019, the organization's board of directors consists of David P. Lewis (chairman), James W. Lintott (treasurer), Philip English, Dennis Groth, Douglas Holtz-Eakin, Stephen Kranz, Sarah McGill, David Nicholson, Pamela F. Olson, Tom Roesser, and Scott Hodge (Tax Foundation president). Finances The Tax Foundation accepts grants from foundations, corporations, and individuals. It does not solicit or accept funds from government sources. The Tax Foundation has earned a 3 out of 4 star financial rating and 4 out of 4 star accountability and transparency rating from Charity Navigator. Activities The Tax Foundation publishes several major studies, including Options for Reforming America's Tax Code, which details the economic and revenue impact of over 80 potential changes to the U.S. tax code. The group uses its Taxes and Growth (TAG) macroeconomic model to simulate the effects of tax policies and produce conventional and dynamic estimates of potential changes in revenue, GDP, wages, employment, and the distribution of the federal tax burden. The TAG model is a "neoclassical, comparative-statics economic model coupled with a tax return simulator". The economic model estimates supply of labor and cost of capital based on marginal tax rates calculated by the tax return simulator. Since 2014, the TAG model has been used to analyze legislative and campaign tax proposals, including the Tax Reform Act of 2014 proposed by Dave Camp, plans put forth during the 2016 presidential campaigns, the House GOP's 2016 tax reform blueprint, and the Tax Cuts and Jobs Act.
