The Impact of Tax Revenue from Capital Gains Realizations on State Income Tax Revenue and Budget Conditions

Abstract

We explore the effect of the rapid increase in capital gains realizations on state income tax revenue during the 1990s and 2000s, and the effect that this had on state fiscal decisions regarding the use of these revenue. We find wide variation in the growth of capital gains realizations across states and that the growth in capital gains had a significant effect on state income tax revenue for many states. We find that states used a sizable portion of the additional revenue from capital gains to fund reserves in the year the revenue was generated, and that capital gains revenue lead to some reductions in taxes but not to increases in expenditures. The evidence suggests that states were conservative in their use of capital gains related revenues.
