“…In part, this may be induced by the tax structure, which gives preferential treatment to the self-employed in comparison with employees. The total tax burden for an average employee (including social security contributions) reached 37% in 2013, compared to 28% for an average self-employee, yet self-employees' average gross earnings were 34% higher than those of employees (Araújo and Maleček, 2015). For instance, based on an annual cash-flow threshold of CZK 2 million, self-employees benefit from income tax deductions of up to 80% of their cash-flows or revenues for self-employed workers in agriculture, craftsmen, etc., 60% for other selfemployed workers, 40% for artists, writers and other intellectual activities and 30% for revenues from house rental and associated categories, which comes on top of preferential treatment with respect to social security contributions.…”
