Technical standards for electronic invoicing systems published (Order HAC/1177/2024).

On October 28th 2024, the Spanish Official State Gazette (BOE) published Regulation HAC/1177/2024, which establishes mandatory technical standards for invoicing systems in Spain. These new regulations introduce enhanced requirements for invoicing software, with a focus on data integrity, retention and traceability to support secure and compliant accounting. In addition, the use of QR codes on invoices enables direct access to AEAT records, streamlining verification processes. You are welcome to read the full document.

What is Verifactu and why is it important?

Verifactu was launched by the Spanish government to improve transparency and security in tax reporting. The standardised transmission of tax-relevant data is intended to effectively combat tax fraud and irregularities. The regulation primarily affects companies that use invoicing software to process sales and other tax-relevant transactions.

The Verifactu system and the Ley Antifraude

The Verifactu system enables companies to meet the requirements of the Verifactu Agencia Tributaria. By integrating Verifactu, companies can validate their invoices in real time and ensure that they comply with the requirements of the anti-fraud law. The Verifactu law is essential and aims to prevent tax fraud and ensure the transparency of tax processes. With Verifactu, companies can issue their invoices efficiently and securely in accordance with the requirements of the Agencia Tributaria and the anti-fraud law.

Important deadlines and requirements for Verifactu

The deadlines for software developers remain the same: 9 months from the date of publication, with a deadline of 29 July 2025. For taxpayers, the date also remains unchanged (July 2025), but the tax authority has indicated that this date could be extended until official confirmation.
In order to meet the requirements of Verifactu, billing systems must comply with specific criteria for data integrity, time stamping and data storage. Here is an overview of the most important requirements:
  • Billing systems must enforce data integrity and ensure that data records remain unaltered.
  • If integrity cannot be guaranteed, a warning must be generated, and the event should be reported.
  • A margin of error of up to 60 seconds is permitted for timestamps of billing data records.
  • All billing data records must be retained, although storage outside the original system is permitted.
  • Billing entries, including new and cancelled records, must be stored in XML format with UTF-8 encoding, with the specific structure, content and format specified in the order.
