VERI*FACTU is a Spanish regulation, approved in 2023, that sets technical rules for billing software. It requires businesses to use certified invoicing software (SIF) that ensures invoice traceability and sends data to the Spanish Tax Agency (AEAT).
The regulation applies to all taxpayers, including freelancers and small businesses, except for those already using Spain’s existing SII e-reporting system.
Note: VERI*FACTU is different from Spain’s B2G (business-to-government) and upcoming B2B e-invoicing rules. Companies must follow each requirement separately.
Because of delays in publishing the technical details, Spain’s Tax Agency has postponed the rollout by six months:
- January 1, 2026 – For companies that pay corporate income tax,
- July 1, 2026 – For all other taxpayers,
To help businesses prepare, the AEAT has launched several VERI*FACTU digital services:
- Web tools to submit and view invoice data,
- QR code features to verify invoice authenticity,
- Options to download both sent and received invoices.
This delay gives businesses more time to get ready, but all affected taxpayers will still need to upgrade their systems and follow the new rules by the revised deadlines.

Minor modifications—such as invoice layout tweaks—are allowed under the existing certification, but changes impacting compliance require a new Responsible Declaration. Read more

A SIF is uniquely identified by a combination of three elements: the operator’s NIF (OEF ID), a two-character SIF ID assigned by the software manufacturer, and the installation number. Read more
