This article explores the impact of tax policy on economic growth in the states within the framework of an endogenous growth model. Regression analysis is used to estimate the impact of taxes on economic growth in the states from 1964 to 2004. The analysis reveals a significant negative impact of higher marginal tax rates on economic growth. The analysis underscores the importance of controlling for regressivity, convergence, and regional influences in isolating the effect of taxes on economic growth in the states.
