On the construction of marginal federal personal and social security tax rates in the U.S

Abstract

In this article, I correct and extend my earlier series on marginal federal personal income tax rates. I also construct a measure of the marginal Social Security tax rate and add this to the income tax rate to obtain a measure of the effective marginal tax rate on income due to federal taxes. Finally, I compare my series on marginal income tax rates and its method of construction with those of Barro and Sahasakul.
