“…In this study, we seek to provide evidence on whether financial constraints explain variation in tax outcome volatility across firms. 2 Interest in the volatility dimension of corporate tax planning has accelerated in recent years (Drake et al, 2019;Delis, Hasan, & Karavitis, 2020;Guenther, Matsunaga, & Williams, 2017;Neuman, 2019). Providing evidence on the determinants of tax rate volatility is critical because recent studies find that firms with volatile tax rates face significant consequences, such as higher costs of capital (Saavedra, 2018), lower firm valuation (Jacob & Schütt, 2020), more information asymmetry (Bratten, Gleason, Larocque, & Mills, 2017), less value relevant after-tax earnings and cash flows (Drake et al, 2019), and higher audit fees (Abernathy, Finley, Rapley, & Stekelberg, 2019).…”
