Spain’s digital invoicing landscape is changing fast, and Verifactu is at the center of it. With new regulatory updates rolling out in 2025–2026, businesses—especially freelancers, SMEs, and foreign companies operating in Spain—must prepare for a new era of real‑time invoice reporting.

Whether you’re already using invoicing software or still issuing invoices manually, the latest changes affect how you create, store, and transmit invoices. This guide breaks down everything you need to know, with a focus on compliance and practical steps.

What Is Verifactu?

Verifactu is Spain’s real‑time invoice reporting system, designed to ensure invoice integrity, traceability, and anti‑fraud compliance. It requires invoicing software to:

• Generate invoices in a tamper‑proof format
• Send invoice records automatically to the AEAT (Spanish Tax Agency)
• Maintain a secure audit trail
• Prevent deletion or alteration of issued invoices

If you use certified invoicing software, you are automatically compliant.

Latest 2025–2026 Updates You Should Not Ignore

1. Mandatory Verifactu Compliance Is Approaching

The Spanish government confirmed that Verifactu will become mandatory for most businesses once the final technical regulations are published. The transition period will be short, so companies should prepare now.

Key points:

• All invoicing software must be certified
• Manual invoicing will be heavily restricted
• Real‑time invoice transmission will be the default

2. New Technical Requirements for Invoicing Software

The latest updates introduce stricter requirements:

• Hash chains to ensure invoice integrity
• QR codes on all invoices
• XML‑based structured invoice files
• Automatic AEAT communication endpoints
• Immutable invoice logs

If your software does not meet these requirements, it will not be certified.

3. Foreign Companies With a Permanent Establishment Must Comply

If you operate in Spain through a Permanent Establishment (EP), you must:

• Use Verifactu‑compliant software
• Issue invoices from your Spanish NIF
• Store invoice data in Spain or in an EU‑compliant environment

This applies even if your headquarters are abroad.

4. Real‑Time Reporting Will Become the Standard

The AEAT will receive invoice data instantly, similar to the SII system used by large companies.

Benefits:

• Faster VAT refunds
• Reduced inspections
• Automatic cross‑checking with clients and suppliers

But it also means:

• Zero tolerance for errors
• No possibility to “fix” invoices after issuing
• Higher penalties for non‑compliance
