So Lexis, you do not have to pay income tax anywhere ? Lucky you.
Not everybody is in your situation. So your salary is gross. If you do not pay any taxe or social can be your choice, but still your salary is gross.
So specify your nationality and the country you are living in, maybe not the same, and where your family is living in. All thing that may affect your taxation. Because in your situation I would have to pay taxes here and there. Either under confair or local contract.
