Response from the Financial Entity:Error 99

The "[code 99] Technical error" is a response from the collaborating entity that may occur when trying to make a payment, or a query of the same, in the payment gateway of the AEAT.This error prevents the operation from being completed and, therefore, the NRC is not generated as proof of payment.

The server of the bank with which you are carrying out the procedure may have technical problems.It is recommended that you contact this entity for further information.

Alternatively, you can try to make payment later (perhaps it is just a server error) or indicate an account with a different bank, of which you are also the account holder.

Take into account that the Tax Agency is not responsible of the lack of response by the Collaborating Organisation and will not take any responsibility in the admission of order of charge.However, direct debit application forms signed digitally with electronic certificates will be kept safe by the Tax Agency.
