We contribute to the empirical literature on the effective incidence of corporate income taxation by using the German Business Tax Reform of the year 2000 (GBTR 2000) as a natural experiment. Its effect on wages in the manufacturing sector is identified by means of a difference-in-differences analysis that uses French firms as comparison group. We provide evidence that GBTR 2000 led to a significant and sizeable wage effect. For 2001, the first year after GBTR 2000 took effect, we estimate a short-run effect that implies a wage increase of 7.9 percent. Due to the dynamic nature of the empirical model used, the incidence effect grows gradually over time during the evaluation period.
