Request for Correction of Contribution Basis Report.

Listado de formularios que empiezan por la categoria "null".

Acceso al servicio


People who have worked as an employee in any of the following Schemes:

  • General Scheme.
  • Special Scheme for Sea Workers (Group I).


With this service you can request correction of the information contained in contribution basis reports and the addition of missing information in these reports. To do this, as much available information as possible must be included in the service access form for correction or addition (dates, company name, province).

Once the correction of data is requested, you will be emailed a receipt of your request by the General Treasury of the Social Security and the identification number associated with the request (which is to be cited for any clarification regarding the submitted request), and so your email address must be included in the form.

After the request is processed, the interested party will be notified by email, and a new contribution basis report can be requested, if desired.


  • To access this service you must have a digital certificate included in the list of accepted certificates, and also meet other technical requirements.
  • Also, if this certificate was not obtained at a Social Security Office, the identification details on the digital certificate must match those held by Social Security.
