Using estate tax return data from 1916 to 1996, we investigate the impact of the estate tax on reported estates, which reflects the impact of the tax on both wealth accumulation and avoidance. An aggregate measure of reported estates is generally negatively correlated with summary measures of the level of estate taxation, holding constant other influences. In pooled cross-sectional analysis that makes use of individual decedent information, the relationship between the concurrent tax rate and the reported estate is fragile and sensitive to the set of instruments that are used to capture exogenous tax rate variation. However, the negative effect of taxes appears to be stronger for those who die at a more advanced age and with a will, both of which are consistent with the theory of how estate taxes affect altruistic individuals. Finally, we find that the tax rate that prevailed at age 45 or ten years before death is more clearly (negatively) associated with reported estates than the tax rate prevailing at death. Future research should concentrate on developing lifetime measures of the effective tax rates and on better measurements of the effective tax rate for married couples.
