Tax compliance under tax regime changes

Abstract

In this paper we focus on the compliance effects of tax regime changes. According to the economic model of tax evasion, a tax reform should affect compliance through its impact on tax rates and incentives. Our findings demonstrate the importance of at least two further effects not covered by the traditional model: First, reform losers tend to evade more taxes after the reform. Second, a reform from a proportionate to a progressive system decreases compliance compared to a switch in the reverse direction. However, the level of compliance is generally higher under a progressive than under a proportionate regime. --tax reforms,tax compliance,experiment
