This article introduces a new methodology to investigate the effects of the 1986 Tax Reform Act (TRA) on corporate dividend policy. The methodology employs a modified version of Rozeff's (1982) model to control for the potential effect of underlying influential variables. The empirical results show there is no widespread reaction to the 1986 TRA passage on the aggregate level of dividends and only modest support for an industry-related dividend effect. We also find that firm size does not play a significant role in dividend policy reaction to the 1986 TRA.
