The legal framework for the RED  System is based on the Ministerial Order of 3 April 1995 (BOE  of 7 April) and on the Resolution by the General Directorate of the TGSS , of 23 May 1995 (BOE of 7 June) that implements the foregoing.

The RED System authorisation is granted to those companies, professionals and other parties that, as part of their activity, fill in and submit contribution documents on behalf of the taxpayers subject to the contribution obligation.

The authorisation is given to the groups described above that belong to the following schemes:

• General Scheme, (including: Special Scheme for Artists, Special System of Fruit, Vegetables and Vegetable Preserves, Special System of Handling and Packaging Fresh Tomatoes, Special System for Permanent Intermittent Workers who provide services to Film Screening Companies, Dance Halls, Discos and Nightclubs, Special System for Permanent Intermittent Workers who provide services to Market and Public Survey Companies, and Special Agricultural System).
  
  
• Special Schemes for Seafarers (Employed Workers)  and Coal Mining.

When the authorisation is granted, the following documents will be issued:

• Resolution granting or denying the authorisation.
  
  
• Installation instructions
  
  
• User training manuals
  
  
• Information and regulations concerning tests and practice in the area of contributions and affiliation.

Yes. If the conditions in the authorisation are not complied with, this can lead to its being suspended or revoked.

Yes, but only if the holder of an authorisation changes, as when the person who represented the company or office given an authorisation is replaced or the business address changes.

The person responsible for the use of the authorisation is the owner of the office or the legal representative of the company. If this is the main user, he or she can delegate its use to personnel with whom he or she has a labour relation or to a self-employed collaborator who will use it as a secondary user. The personnel must be listed as authorised users with access to the TGSS system.

The main user is the person who made the application for the secondary users, when the application is approved by the TGSS. Each of them must have a SILCON Certificate to be able to use the RED System. Therefore, the main user is responsible for the secondary users. It is very important that the main user request of the authorisation for any secondary users who no longer need it, for any reason.

It depends on the activities of the company or office. In theory, there will only be one main user plus as many secondary users as the holder of the authorisation needs.

Each user linked to that authorisation will use his or her own SILCON Certificate for each operation made on the RED System, so that each operation is linked with its originator.

Yes, the holder of the authorisation can register, delete or make changes to secondary users using the RED System. The holder of the authorisation can also view the details of any or all the users registered with the authorisation. This feature is located in "Authorisation Management", in the RED Services On-Line menu.

Yes, any user can view any or all of the Contribution Account Codes and NAFs that have been assigned when making the enquiry. This feature is located in the "Authorisation Management" section, in the RED Services On-Line menu. 

A request can be made to rescind a CCC or NAF through the service available in the RED System: Online/ Authorisations Management/ Allocation or Rescission of CCC or NAF, or by filling in the corresponding form (FR104 or FR115).
