Spillover effects of VAT self-enforcement properties : evidence based on the replacement of business tax with VAT reform

In accordance with the purchasing tax-deduction method and the receipt-based value added tax (VAT) system, the same transaction can be recorded by two firms, which creates self-enforcement properties, thereby restraining tax avoidance. Using the Replacement of Business Tax with VAT reform in China, this paper adopts a difference-in-differences design to investigate the spillover effects of VAT self-enforcement properties on corporate income tax avoidance by manually collating information about suppliers/clients of listed firms. As the listed firms' suppliers/clients switch from paying business tax to paying VAT, there is a striking decline in their corporate income tax avoidance behavior. This effect is pronounced in firms with closer upstream and downstream correlations, higher information complexity and stronger incentives for tax avoidance.
