Making a mistake when billing a client is a common part of running a business: a typo in the client's tax number, a missing description, or an incorrect VAT rate. However, with Spain's anti-fraud regulations, many expat freelancers and business owners wonder what happens when an erroneous invoice is submitted directly to the Tax Agency (AEAT).
The practical answer is reassuring: an honest mistake does not trigger an automatic penalty, provided you correct it through the proper channels detailed in the VeriFactu guide for freelancers.
Inalterability: The End of Editing or Deleting Invoices
The fundamental change under VeriFactu is strict traceability. Certified billing systems generate tamper-proof records linked by cryptographic chaining. This means that you can never edit or delete an invoice once it has been generated, as doing so would break the digital audit trail.
If you issue an incorrect invoice, your software has already signed or dispatched it to the AEAT servers. Trying to overwrite it or erase database entries is considered a severe violation under the rules on VeriFactu fines and penalties.
The Proper Procedure: Corrective Invoices and Cancellations
To amend an error without compromising historical billing records, you must follow the official tax procedure:
* Corrective invoice by differences (Factura rectificativa por diferencias): Adjusts monetary values, tax bases, or VAT amounts if you overcharged or undercharged.
* Corrective invoice by replacement (Factura rectificativa por sustitución): Formally cancels the prior invoice data and issues a comprehensive replacement document in a single record.
* Electronic cancellation record (Registro de anulación): Used when an invoice was issued completely in error for a non-existent or duplicate transaction, notifying the AEAT of the cancellation reason.
Both approaches ensure that every correction is chronologically chained within the certified software log. Keep in mind the official implementation timetable: corporate entities must comply by January 1, 2027, while sole traders, freelancers, and micro-enterprises must comply by July 1, 2027.
