Taxation and Self-Employment
Abstract
In this paper I study the relation between self-employment and the tax rates on wages and on self-employment income. Using variation in the statutory tax rates across countries, industries, and occupations, I find that while the share of self-employed is strongly positively correlated with the tax rate on wage income, it is weakly negatively correlated with the tax rate on self-employed income. The asymmetry between the effects of the tax rates suggests that those who choose self-employment partly do so in order to evade taxes. This extensive margin of adjustment – between employment and self-employment – should be taken into account when considering the effects of tax rates on labor income, on taxable income and on welfare.
