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 ACCEPTOtherwise, click CANCEL".
If the account only has one account holder and therefore only one certificate is to be use, click "CANCEL" to continue with the process.
Click "ACCEPT" only if the account has dual ownership to sign with the second certificate.Java will be required in this mode, so you must perform all the checks and configurations recommended for procedures that still use Java.
In the case of dual ownership, 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 coincide with the authorised representatives of said account.
However, the NIF given at the time of payment must be that of the taxpayer
