An Examination of the Impact of Tax Avoidance on the Readability of Tax Footnotes

Due to the proprietary nature of tax returns, the tax footnote is the primary source of information for stakeholders about a firm's tax position. However, studies suggest the tax authority acquires information in tax disclosures, creating a trade-off for managers on whether to provide decision-useful information for stakeholders or conceal information from the tax authority. We investigate this trade-off by examining the readability of tax footnotes. We find a positive association between tax avoidance and tax footnote readability for firms with tax avoidance below the industry-year median, consistent with managers highlighting good performance in the form of tax savings with straightforward disclosures. In contrast, we find a negative association between tax avoidance and tax footnote readability for firms with levels of tax avoidance above the industry-year median, consistent with managers concealing tax avoidance from the tax authority. Reinforcing these results, we find that investors place a premium (discount) on tax avoidance when the tax footnote is straightforward in firms with tax avoidance below (above) the industry-year median.
