Verifactu implementation period begins for software vendors
The Ministerial Order approving Spain’s Anti‑Fraud Law regulations came into effect on October 28, 2024, initiating a nine-month grace period for billing software vendors. From July 29, 2025, POS, ERP, and PMS providers must comply with the Verifactu technical requirements. For companies and freelancers with annual turnover below 6 million EUR 2026, the mandatory deadline to use Verifactu-compliant software will be established.
Verifactu: implementation deadlines
The Ministerial Order's approval sets two pivotal dates:
Verifactu will be mandatory for billing software vendors ➡️ July 29th, 2025
All invoicing software vendors (or other management software that includes the possibility of invoicing) must adhere to the technical requirements of the Anti-Fraud Law. This includes both options: invoicing with immediate sending to the tax authorities (Verifactu) and the option of electronic signature and chained hash (Non-Verifactu). The 9-month countdown to mandatory compliance begins today.
Using Verifactu software will be mandatory for companies and freelancers ➡️ 2026
On April 1, 2025, the Council of Ministers approved a modification to Royal Decree 1007/2023, which directly affects the Verifactu implementation timeline. The goal is to offer taxpayers more time to adapt.
Following this change, the enforcement dates will vary depending on the type of taxpayer:
- January 1, 2026: enforcement date for corporate income taxpayers (art. 3.1.a), i.e., legal entities.
- July 1, 2026: enforcement date for individuals (freelancers/self-employed).
Penalties for non-compliance with Verifactu
A distinctive feature of the Spanish legislation, unlike other fiscal regulations in Europe, is that in instances of manual or automatic invoicing using non-anti-fraud software, penalties will be applied to both the company or self-employed individual and the entity responsible for marketing the invoicing software employed.
On the one hand, businesses or freelancers utilizing software enabling B accounting or opting not to use anti-fraud software for invoicing (such as continuing with manual methods or Excel) will be subject to fines of up to €50,000 per year.
Non-compliant software, allowing irregularities in invoicing, may incur penalties of up to €150,000/year for the software vendor. Therefore, it is highly recommended to make sure that your company uses anti-fraud software certified by the AEAT.
On a different note, while official information is yet to be disclosed, there are indications that companies proactively adhering to the Anti-Fraud Law may receive tax deductions. This precedent has been observed with TicketBAI in the Basque Country, suggesting a similar approach for Verifactu across the rest of Spain.
