Specially for spanish resident designers (paypal and "Hacienda")

Good morning everybody.

This post is especially dedicated to the spanish designers whom lives in the Spanish territory. I decided to start an account with envato, and inmediately “Hacienda” comes into my head. I think Envato is amazing and a universe of opportunities, but as spanish designers now, here in spain “Hacienda” (the gobernement bill killer) is everywhere. What is about to work here and have a good relationship with Hacienda? What about to have “nice” (1000-3000€ or more) amounts of money in your paypal account each month? Its recommended to be “Autonomo” (Independent worker)?

Many thanks!!!

Nobody of Spain here with this kind of questions? Extrange…
