4.3.1. Identification, authentication and signature. Cl@ve PIN

The Tax Agency participated in the design and implementation of the Cl@ve system, a common platform of the State Administrative Public Sector for identification, authentication and electronic signature through the use of private keys. This project meets the need for homogeneity, simplicity and shared services expressed in the CORA report. The Tax Agency assumes the responsibility for its activities in the areas which the regulations of this platform assign to it. One of the identification and authentication mechanisms offered by the Platform is Cl@ve PIN, implemented by the Tax Agency.

It should be pointed out that since 2015, Cl@ve PIN could be used to request practically all tax certificates and to carry out almost all Tax Agency procedures for individuals, as well as to pay tax settlements.

In 2019, it was made easier for natural persons to submit all their documents in the electronic registry using Cl@ve PIN, which makes it easier to carry out numerous procedures that previously required having an electronic certificate.
