“…There is a lack of empirical research about the level of active tax management or tax aggressiveness of family firms (Desai & Dharmapala, 2006;Scholes et al, 2009); moreover, the literature reports contradictory results. Whereas there are studies showing a positive relationship between family firm status and tax aggressiveness (Gaaya et al, 2017;Koverman & Wendt, 2019;López et al, 2019;Mafrolla & D'Amico, 2016;), the opposite relationship has also been found (Bauweraerts & Vandernoot, 2019;Brune et al, 2019;Chen et al, 2010;Sánchez et al, 2016;Steijvers & Niskanen, 2014). In addition, while a large body of literature has focused on the comparison between family and non-family firms, private and public firms, or large and small private firms, few studies have analysed the extent to which the well-known heterogeneity of family firms (Brigham et al, 2019;Chua et al, 2012;Stanley et al, 2019) may affect their tax decisions and thus influence the differences in behaviour compared to non-family firms.…”
