Message If the account has dual ownership
When accessing the payment of taxes with the electronic certificate of a representative or legal entity, a message will appear indicating:
"If the account has two account holders, you must also sign with the certificate of the second account holder. If you are going to sign with the certificate of both account holders, click ACCEPT Otherwise, click CANCEL".
If the account only has one holder and is therefore only going to be signed with one certificate, press "CANCEL" to continue with the process.
Press "ACCEPT" only if the account has dual ownership to sign with the second certificate. Java will be required here, so you must perform all the recommended checks and configurations for the procedures that still use Java.
In the case of two account holders, it is also necessary to verify that the two certificates of the legal entity holding the account are installed in the browser, whose representatives must also match the authorised representatives of said account.
The NIF of the taxpayer that must be completed at the time of making the payment will always be that of the declarant or taxpayer.
