This study aims to examine the relation between tax-avoidance and information transparency. The samples are listed firms ranked by the Information Transparency and Disclosure Ranking System (IDTRS) of the Securities and Futures Institute (SFI) from 2011 to 2012, and the ranking results of IDTRS are used as the proxy of information transparency. The result shows that, after controlling for earnings management, only the positive BTD is negatively associated with information transparency. It is consistent with our conjecture that information transparency mitigates tax avoidance behavior.
