The top marginal federal income tax rate has varied widely over time (figure 2). The top rate was 91 percent in the early 1960s before the Kennedy/Johnson tax cut dropped it to 70 percent. In 1981, the first Reagan tax cut further reduced the top rate to 50 percent, and the 1986 tax reform brought it down to 28 percent. Subsequent legislation increased it to 31 percent in 1991 and to 39.6 percent in 1993.

Alternatively, a handful of states use their own definition of income, but even these states rely heavily on federal rules when establishing their tax base. For combined state and local revenue, Maryland relied the most on the individual income tax in 2017, with the tax accounting for 29 percent of its own-source revenue. Some states impose a flat tax while others offer varying rates of taxation depending on the amount of income generated.
