This paper presents new information on the fraction of adjusted gross income, and of wages and salaries, that is reported by taxpayers in the top one half of one percent of the income distribution. This corresponds to roughly five hundred thousand households in the late 1990s. This paper relies...

The share of pre-tax income flowing to the top of the UK income distribution increased continually and substantially in the three decades leading up to the financial crisis, but has changed little since 2013. Using microdata sampled from UK tax records, we describe the nature of top incomes in...

The Maximum Tax on Personal Service Income was intended to reduce the maximum marginal tax rate on earned income to 50 percent.

Wage inequality has been significantly higher in the United States than in continental European countries (CEU) since the 1970s. Moreover, this inequality gap has further widened during this period as the US has experienced a large increase in wage inequality, whereas the CEU has seen only...

This paper summarizes the main findings of a recent literature that has constructed top income shares time series over the long-run for more than 20 countries using income tax statistics. Top incomes represent a small share of the population but a very significant share of total income and total...
