This study examines how institutional investors' corporate site visits affect tax avoidance. Using quantile regressions, we find that corporate site visits decrease tax avoidance for firms at high levels of tax avoidance and increase tax avoidance for firms at low levels. The effect of corporate site visits on tax avoidance is stronger for firms subject to a weaker information environment, which suggests that institutional investors acquire additional firm-specific information via corporate site visits and play a more effective monitoring role. We also find that visitors who visited low-tax firms in prior years share tax-planning knowledge with high-tax firms which they visit in the current year. The effect of tax knowledge transfer is more pronounced when the visitors are from incumbent institutional shareholders. This study identifies corporate site visits as a channel via which institutional investors serve as monitors to managers and as facilitators of tax knowledge transfer.

ABSTRACT Audits of internal control over financial reporting (ICFR) are typically “integrated” with the audit of the financial statements (FSs)—both audits are conducted by the same audit firm, which designs procedures to satisfy the objectives of both audits simultaneously. A common assumption is that integrating the two audits is more effective and efficient than performing them separately. However, this assumption has not been tested empirically. Using a sample of Chinese companies that employ different audit firms for their FS and ICFR audits (i.e., nonintegrated auditors), we find evidence that challenges this assumption. Specifically, we find ICFR audit quality is higher for nonintegrated audits compared to integrated audits. Moreover, total audit fees are lower for nonintegrated audits, despite higher ICFR audit fees.
