Step-by-step checklist so that your business is prepared without last-minute stress
The Moment of Truth Has Arrived
A week after our first article on VeriFactu, the queries have not stopped. Apparently, many believed that January 2026 was in another galaxy. Let us remind you: there are exactly 6 months left for companies (January 1, 2026) and 12 for self-employed workers (July 1, 2026).
Time doesn't stop because your agency told you "we'll see."
In these seven days, the software certification window is already open and the first technology providers are beginning to become saturated. The AEAT has been clear: VeriFactu is mandatory for Corporate Tax taxpayers from January 1, 2026, and for self-employed workers from July 1, 2026, with perfectly defined sanctions for non-compliance. But don't worry, we can always wait until the last minute and then improvise.
VeriFactu is Spain's specific invoice verification system, implemented within the framework of the Spanish Anti-Fraud Law. Its main objective is to ensure the veracity and security of commercial transactions through digital invoices, sending the records directly to the Tax Agency (AEAT). It is not a suggestion, it is a legal obligation with clear sanctions for non-compliance.
This guide gives you everything you need: a 90-day schedule, real implementation costs, common mistakes you can avoid, and an emergency plan in case you decide to act in November (spoiler: it will be more expensive).
