Comparing the top and the bottom income earners: Distribution of income and taxes in the United States

Abstract

Tax reform is again at the center stage as Congress grapples with ideas to reduce the US budget deficit and the country readies itself for another election year. Given this unusually charged tax reform season, populist and party rhetoric appears to the general population to have largely replaced reasoned debate as politicians, economists and pundits “cherry pick” facts to justify their claims. Our contribution to the current debate on tax equity is that this is one of the very few studies that jointly consider the impact of payroll and income taxes. Most tax equity studies focus only on the federal income tax and as such issue misleading implications. It is important to jointly consider payroll and income taxes because (a) for taxpayers in lower income ranges, the payroll tax burden outweighs the income tax burden, while (b) for higher income taxpayers income from wages above $106,800 ($110,000 in 2012) are payroll-tax free, and (c) other sources of income, namely dividends and capital gains, are not subject to payroll taxes at all. Thus, we provide a more comprehensive picture of the overall progressivity (or lack thereof) exhibited by the current tax laws. In addition, we also consider how some often-raised tax proposals would prospectively affect income inequality and tax progressivity.
