What is Verifactu?

Verifactu is the rule from the Spanish tax agency (AEAT) that changes how invoices are created and stored. From 2026, all invoicing software has to record every invoice in a way that can't be changed in secret and has to include a verifiable QR code.

In short: Verifactu makes sure every invoice is real and traceable. It applies to autónomos and small businesses that issue invoices with software and aren't in SII.

‍

Why was Verifactu created?

Until now, invoices created with software could be edited or deleted without leaving a trace. That allowed double bookkeeping: one set of numbers for the client, another for Hacienda.

Verifactu closes that door by forcing every invoicing program to:

• Keep a secure record of every invoice.
• Include a QR code that anyone can scan to verify it.
• Optionally send the data to the AEAT in real time.

Result: full transparency and the end of hidden or tampered invoices.

‍

Who does Verifactu apply to?

It affects you if you issue invoices with invoicing software and you're not in SII (Suministro Inmediato de Información).

Excluded: taxpayers already in SII, the large companies that send their VAT data to the AEAT every day.

If you're an autónomo, an SL, or a small agency, this rule is for you. Read more about the autónomo regime.

When does it kick in?

Rollout is in two phases:

• 1 January 2026: for corporate-tax payers (companies).
• 1 July 2026: for autónomos and small entities.

Software vendors adapted their products through 2025. The AEAT services are already live. You can start with a compliant program today.

What changes on your invoices?

• QR code: mandatory on every invoice. Scanning it opens an AEAT page with the basic data.
• "VERIFACTU" label: only appears if your software sends the data to the AEAT in real time.
• Automatic numbering: invoices are numbered sequentially. You can't change dates or delete invoices afterwards.
• Traceability: each record is linked to the previous one. If you try to alter one, the AEAT detects it.
• Secure archive: the software stores XML copies of every invoice in an unalterable format.

‍

What to do now

1. Pick a Verifactu-compatible program. renn automatically generates invoices with the official QR, stores secure XML records and complies with the AEAT with no extra steps.
2. Test invoice issuance. Check how the QR appears, how invoices are numbered and where the records are stored.
3. Review your process. Define who issues invoices, how to correct or void one, and how to keep the files.
4. Train your team. The software does the heavy lifting, but someone has to know how to use it well.

If you already use renn, you don't need to do anything else: your invoices are compliant from day one.

‍

What does the AEAT offer?

The AEAT has a basic free app in Verifactu mode. It generates invoices, adds the QR and sends them to the AEAT. It's designed for people who issue very few invoices a year.

If you invoice regularly or need automation (bank sync, expense capture, real-time VAT view), professional software is the right choice. Here's how to comply with Verifactu at zero cost.

‍

What if you don't comply?

• Using non-compliant software: fines of up to 50,000 € per year.
• Selling or distributing non-compliant software: penalties up to 150,000 € per year.
• Minor breaches (missing QR, wrong format): per-invoice fines.

The AEAT's goal is for everyone to use secure systems, not to collect fines. But preparing in time avoids problems.

‍

Bottom line

Verifactu isn't bureaucratic friction. It's the new standard for issuing invoices securely and transparently. For autónomos it simply means using a certified program that includes the QR, keeps secure records and follows the AEAT's structure.

2026 is here. Compliance is mandatory. Start with renn for free or check the full Verifactu guide for all the details.
