Hi guys-

  Can anyone tell me the income limit for being exempt from filing taxes here in Spain? I make about 10-11k (euros) per year.

Thanks

Even if you do not have enough income to actually pay tax it is still worth making a declaracion (filing) if you want (not that it is really optional) to be fiscally resident and derive the benefits.

Lots more here
