To be able to consult the services of the State Tax Administration Agency (AEAT) of Via Oberta, each organization must request a medium-level electronic seal assigned exclusively for use of the services of AOC. When this is about to expire, the following steps must be followed to renew it:
1. Request seal renewal
You will have to access EACAT and request an electronic seal from AOC by indicating the option “ Exclusively assigned for use of AOC services ” in the “use of the certificate” section of the request.
As this is a stamp assigned to AOC, reception and download will be our responsibility.
2. Download the seal's public key
Once the AOC has downloaded the seal, the responsible person will receive an email with confirmation and they will be able to download the public key of the certificate from the subscriber folder to provide it to the AEAT.
3. Send documentation to the AEAT
Access the corresponding form through the AEAT's electronic office depending on the information required by your organization:
- Tax purposes form * (all those purposes that involve tax management)**
- Form of non-tax purposes * ( public procurement; authorizations, licenses, permits and approvals; grants, scholarships and subsidies; benefits, human resources, sanctions, etc.)**
*In the Management menu select: Presentation of authorization forms in standardized supplies
**Whether the purpose is tax-related or not is indicative and it is your organization that must determine which of its own procedures it considers tax-related and which are not.
In both cases you will need to attach:
- The electronic certificate replacement form (web services) that you will find on the Tax Agency website in the "Information" section
- The public key of the seal assigned exclusively for use of the AOC services with the .cer or .crt extension and compressed in a .zip file.
4. Send confirmation of authorization to AOC
Once the AEAT responds, you must open a support request or have the person responsible for the service reply to the notification email we sent to inform you of the steps to follow to renew the stamp for the AEAT, attaching the following:
- The confirmation email from the AEAT authorizing the new certificate (in PDF format)
- The electronic certificate replacement form (web services) that you sent to the AEAT.
Considerations to keep in mind:
- We recommend that you notify us of the renewal of the certificate at least 15 days in advance (you can consult the “ General Conditions for the Provision of Services ” of the AOC).
- AOC uploads new certificates on Wednesdays.
