Verifactu is the name used to refer to softwares that comply with the anti-fraud law and the project of legislation published in February 2022. The Ministerial Order was officially published in the Official State Gazette (BOE) on October 28, 2024, marking the start of the 9-month adaptation period for billing software. The regulation establishes the requirements for billing systems, which must be able to communicate in real-time with the Spanish Tax Agency. Billing software will be required to comply with the VeriFactu requirements starting July 29, 2025.

Who must comply with Verifactu?

Compliance with Verifactu requirements will be mandatory for companies and freelancers throughout Spain, except for all companies with a tax residence in the Basque Country, where the TicketBAI regulation applies. Additionally, Verifactu will not replace the SII (Immediate Supply of Information) system, but it will impact those taxpayers who were not yet required to comply with it (companies and freelancers with an annual turnover of less than 6 million euros). If you are a manufacturer or distributor of ERP software, accounting or management systems, whether B2B or B2C, and your system enables invoice issuance, Verifactu will also affect you because your software must be able to comply with the regulation mandatorily from July 29, 2025.

When am I required to comply with Verifactu?

The Anti-Fraud Law aims to prevent and combat tax fraud and mostly came into effect on October 11, 2021. On October 28, 2024, the Ministerial Order was published, starting the 9-month adaptation period for billing software. Meeting the technical requirements of Verifactu is mandatory for developers and vendors of invoicing software in Spain since July 29, 2025. For taxpayers, the regulation comes into force in 2027, after the postponement announced by the Spanish government: on January 1 for legal entities, and on July 1 for self-employed professionals.

Does Verifactu apply to all invoicing software, such as POS systems, e-commerce platforms, ERP, and marketplaces?

Yes, Verifactu applies to any software in Spain with invoicing capabilities, including POS systems, ERP, hotel management systems (CMS), invoicing programs marketed by independent developers (ISVs), or custom-developed business software.

Does Verifactu also apply to invoices from virtual stores and e-commerce platforms selling online services within Spain and abroad?

Yes, Verifactu will be mandatory for issuing any type of invoice within Spain by a company with a tax domicile in Spanish territory (excluding the three provinces of the Basque Country, which [must comply with TicketBAI](https://www.fiskaly.com/blog/myths-and-facts-ticketbai), and companies based in Navarra, which are subject to a separate fiscal reporting regulation currently under development).
