FAQs
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.
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.

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.
