What taxes do I have to pay?
It depends on whether you are self-employed or working as an employee.
If you are self-employed, i.e. you are free to choose your working hours and place of work, you are running a business. In that case, you will have to pay income tax and maybe turnover tax.
If you are self-employed or run a prostitution establishment and your profits amount to more than approx. EUR24,500 a year, you also have to pay trade tax.
If you are an employee, for example if you work in a brothel or club and have an employment contract there, your employer will pay wage tax to the tax office on your behalf. At the end of the year and when your employment ends, your employer will give you a wage tax statement.
