Purpose

The purpose of this paper is to empirically explore whether and to what extent the changes in state corporate income tax rates affect corporate tax aggressiveness.

Design/methodology/approach

Using a differences-in-differences approach with dynamic treatment, the authors investigate the effect of staggered changes in state corporate income tax rates in the USA on corporate tax aggressiveness.

Findings

Firms become more aggressive in avoiding taxes following state tax increases but are insensitive to tax cuts. The effect of state tax increases on tax aggressiveness is weaker for firms with greater debt tax shields and marginal tax rates. Firms are more likely to shift their operations and relocate their headquarters out of states experiencing tax increases.

Originality/value

To the best of the authors' knowledge, this paper is the first to study the relation between state tax policy changes and corporate tax aggressiveness. This paper finds an asymmetrical pattern of corporate tax aggressiveness in response to state tax changes.

州税的变化会影响公司的税收侵略性吗？美国证据

目的

本文的目的是实证探讨国有企业所得税税率的变化是否以及在何种程度上影响企业税收激进性。

设计/方法/途径

作者使用动态处理的双重差异方法，研究了美国州企业所得税率的交错变化对企业税收侵略性的影响。

发现

企业在国家增税后更加积极地避税，但对减税不敏感。对于债务税盾和边际税率较高的公司，州增税对税收侵略性的影响较弱。公司更有可能转移其业务并将其总部迁出税收增加的州。

原创性/价值

据作者所知，本文是第一个研究国家税收政策变化与企业税收激进之间关系的论文。本文发现了企业税收侵略性的不对称模式以响应州税收变化。
