消费者服务所得税抵免：应对增值税逃税的工具？

This paper analyzes the effects of an income tax credit for hard-to-tax consumer services on evasion of the value-added-tax (VAT). Based on the individual tax files of the universe of VAT payers in Germany, our analysis shows that harnessing incentives for consumers through tax credits fosters firms’ compliance with VAT by bringing in an element of third-party reporting at the last VAT stage. Our results point at strong stimulating effects of the introduction of the tax credit on reported sales as well as on the ratio of reported sales to inputs and we find limited price effects. While two thirds of the revenue losses in the income tax are recovered by an increase in VAT revenues, at least a quarter and up to a half of the revenue gain is associated with a response at the VAT evasion margin. The policy thus fosters considerable formalization effects.
