Self-assessment
Skip information indexSelf-assessments 3
The NRC (Complete Reference Number) is the code generated by the banking entity as proof, to identify tax income. It consists of 22 alphanumeric characters, among which is incorporated, in encrypted form, the information of the NIF of the declarant, the amount, the model, the year and the period.
The NRC will appear on the transaction receipt, along with the summary of the income data. For NRC to be valid, it is important that the data provided to the Collaborating Entity at the time of making the payment is correct.
In declarations and self-assessments that involve income, and for which direct debit has not been selected as a payment method, the NRC generated by the bank must be included in order to make the presentation.
As for the payment of settlements/debts, once the payment has been made and the NRC has been obtained, the process will be complete, without the need to carry out any other actions. You can save the response obtained with NRC as proof of the operation.
If you made the payment through the payment gateway of the AEAT but you have not obtained or do not keep the receipt, you have the possibility of recovering it from the consultation options " All procedures" .
