Spain is entering a new era of digital invoicing—and if you’re self-employed or running a small business, Verifactu is a name you’ll want to remember.
What Is Verifactu?
Verifactu is a new invoicing system introduced by the Spanish Tax Agency (AEAT) to combat tax fraud and improve transparency. Starting in 2026, all businesses and autónomos will be required to use invoicing software that complies with Verifactu standards.
This isn’t just about switching to electronic invoices—it’s about real-time traceability, tamper-proof records, and direct communication with the tax office.
Key Features
- Invoices must be digitally traceable with a unique hash and chronological chain
- Real-time submission of invoice data to AEAT
- QR codes on paper invoices for instant verification
- No more deleting or reissuing invoices without leaving a digital trail
Who Needs to Comply—and When?
- Software providers must comply by July 2025
- Freelancers and businesses must comply by January 2026
- Professionals not using SII (Immediate Supply of Information) must adopt Verifactu or switch to SII
Why It Matters
Using non-compliant software could lead to fines of up to €50,000 for users and €150,000 for providers. So whether you’re issuing invoices from a laptop in Seville or running a small shop in Cádiz, it’s time to prepare.
Stay tuned for a detailed guide on how to choose Verifactu-compliant software, what to expect during the transition, and how to stay ahead of the curve.
