VERI*FACTU: THE NEW ERA OF VERIFIABLE BILLING IS COMING IN 2026

Veri*factu has been talked about for a long time in articles, conferences, etc. so we send you this circular in order to answer your questions about it.

WHAT IS VERI*FACTU?

El Royal Decree 1007/2023 regulates the technical requirements of billing systems (SIF), with the objective of ensuring tax verification and eradicating the implementation of dual-use software or parallel accounting.

Taxpayers can choose between two modalities:

• Verif*fact: the system automatically sends each invoice to the AEAT at the time of its issuance.
• I don't verif*FACT: the records are kept in the software, without automatic submission, but with full traceability and in a secure manner.

You can freely choose either of the two modalities, and change from one to the other over time. However, if the Veri*FACTU modality is chosen, it must be maintained, at least, until the end of the calendar year. The change of modality must be expressly reflected in the responsible statement for the software and it is not possible to alternate them from invoice to invoice. In addition, in the event of a change, all the records generated in the previous modality must be kept and available, so that the Tax Agency can integrate them into the record books.

WHO DOES IT AFFECT?

It is mandatory for:

• Companies subject to Corporation Tax.
• Self-employed workers and professionals who are taxed in personal income tax for economic activities.
• Permanent establishments for non-residents
• Entities in the attribution of income.
• Producers and marketers of billing software.

Excluded are:

• Companies included in the Immediate Information System (SII).
• Taxpayers with no obligation to issue invoices
• Companies in regional territories (Navarre and the Basque Country)
• Those taxpayers who previously billed manually and continue to do so (For example, manually with MS Excel, MS Word, etc.)

WHAT'S NEW IN THE INVOICES

From 2026, all invoices must include:

• QR code, with access to essential information and, where appropriate, direct verification with the Tax Agency.
• “Verifiable Invoice” or “VERI*FACTU” legend, if the issuer operates in Veri*FACTU mode.

These measures will allow the customer to verify the authenticity of the invoice and reinforce fiscal transparency.

KEY CALENDAR

• July 29, 2025: Deadline for software providers adapt their programs.
• January 1, 2026: mandatory for Corporate Tax taxpayers.
• July 1, 2026: mandatory for the rest.

HOW TO PREPARE IF YOU ARE OBLIGED

1. Analyze the current system of billing and detect compliance breaches.
2. Update or replace the software with certified versions.
3. Train staff in the use of the new system and the rectification procedures.
4. Take advantage of aids such as the Digital Kit to finance adaptation.

Remember that the Tax Agency makes available to small entrepreneurs a free online billing application. If you have low billing, you can choose to use this tool, instead of purchasing a third-party program. However, it is necessary to evaluate pros and cons (the public tool will have limitations, for example, it does not allow simplified invoices). In any case, the existence of this option ensures that no obligation is left without a solution: there will be a way to comply, even if there are no resources available for commercial software.

If you have any questions, please contact Eurogrup Tax & Legal SL through the usual means.
