I own an apartment in Barcelona with a a HUT tourist license, which I intend to rent out on a short term basis.
However, I am unsure how I go about paying the income tax and have been told conflicting things:
1. As I am a resident and have a full time job here, I can declare the income as additional income on my normal tax return.
2. I have to register as Autonomo and pay through this.
Can anyone shed any light?
