Informative notes
Brief explanatory information on the presentation of certain information.
Reminder on identification
Please note that the State Tax Administration Agency makes available to you the means to make a correct declaration, especially in terms of identification:
“Third-party consultation service for census purposes” (and the web service)
It is also worth noting that for non-residents who must be informed with the NIF of their country of tax residence (forms 289, 290, 234, ...), it is recalled that to facilitate the validation process of the NIF in other jurisdictions, links are provided to the portals where you can consult the information of each country in relation to the issuance, obtaining and, where appropriate, structure and operation of the corresponding NIF.
