This paper quantifies the dynamic macroeconomic effects of tax changes in Germany, allowing for anticipation effects of preannounced tax reforms. Identification is achieved using a narrative approach, which provides information about the timing of tax reforms. An anticipated cut in taxes has a positive effect on output with a peak multiplier of 1.7, not observed until nine quarters after implementation. This positive effect is accompanied by significant negative anticipation effects on output, consumption, investment, hours worked and wages. Our results suggest that policymakers should take anticipation effects into account when implementing fiscal policy measures.
