Abstract

AbstractThis study examines the determinants of firms' requests for Private Letter Rulings (PLRs) from the US Internal Revenue Service (IRS) and their impact on firms' cash holdings. Our results show that PLR requests tend to be made by firms with more active tax planning, more acquisitions, higher analyst following, higher leverage, and less in‐house tax expertise. We also show that firms with IRS audit red flags are less likely to request a PLR. We use a difference‐in‐difference approach to assess changes in cash holdings following PLR requests and report a decrease in cash holdings for PLR firms, consistent with the notion that PLRs act to reduce tax uncertainty. Our study provides the first empirical evidence about the determinants of PLR requests and complements prior work on tax uncertainty and cash holdings (Hanlon, Maydew and Saavedra, 2017).
