How much is more or less the Spanish income tax,
If I will earn like 1300euro per month,how much will I earn after tax?
(I know I can ask this to the company,its just I dont have a job yet and want to orientate a bit.
Thanks

Probably the best way to have an idea is to use the tax calculations module of the Tax Agency. Even though that is only a reference (final tax numbers are a more complex thing) you can have a pretty good idea in the case of a salary.

The page and SW are in legal spanish I'm afraid.

1) Goto www.aeat.es
2)Descarga programas
3)Programas de ayuda en línea
4)Retenciones IRPF 2002
5)Calcule sus retenciones en linea

Once you fill in all the info it will provide you with a reference of the ammount of anual taxes and the theoretical ammount of taxes "taken" on a monthly bases.I have used it and is not "user friendly" as a procedure.
