“…In the literature, income from self-employment is seen as especially prone to non-compliance (see, e.g., Baldini, Bosi, and Lalla, 2009;Benedek and Lelkes, 2011;Fiorio and D'Amuri, 2005;Pissarides and Weber, 1989). Furthermore, the experiences of Danish (see SKAT, 2013) and US tax authorities (see Christian, 1994;Slemrod, 2007) show considerably lower voluntary compliance among the self-employed compared to wage earners, and the Swedish tax authority identifies high non-compliance in micro companies (Swedish National Tax Agency, 2008).…”
