Verifactu AEAT: dates, free app, downloads

Spain's Tax Agency (AEAT) is launching Verifactu, a new invoicing system that changes how freelancers and small companies issue invoices.
From 2026 for companies and 2027 for autónomos, every invoice must follow the Verifactu AEAT rules to be valid.

Below you'll find what Verifactu means, the main dates, how the free AEAT app will work, and how to prepare your business in time.

‍

1. What Verifactu AEAT is

Verifactu is AEAT's verified invoicing system.
It gives every invoice a unique digital code and QR that prove it was created correctly and hasn't been changed.

For freelancers and small businesses, this means you'll keep issuing invoices as usual, but only through tools that follow AEAT's format.

Why it matters:

• It is mandatory for companies from 1 July 2026 and for autónomos from 1 July 2027.
• It ensures invoices are valid and can't be altered.
• It helps prevent fraud and common invoicing mistakes.

If you still use Word or Excel, you'll need to switch to invoicing software that supports Verifactu.

2. Key dates to remember

• 1 July 2026: Mandatory for companies (SLs).
• 1 July 2027: Mandatory for freelancers (autónomos). Read more about autonomo here.

From these dates, every invoice must include Verifactu's QR and verification code.
Until then, AEAT and software providers are preparing tools to make the switch easy.

3. The free AEAT app and other options

AEAT will launch a free Verifactu app to help small businesses and freelancers comply.
You'll be able to log in through AEAT's website, fill in your invoice details, and the system will automatically send them to AEAT. Each invoice will get its QR code and verification number.

For those who issue just a few invoices a month, this free app will likely be enough.
Those who invoice more often or need additional automation can use other Verifactu-compliant tools, such as renn, which already supports the same AEAT format but integrates features like automatic expense tracking and tax preparation. Both options follow the same AEAT rules - the main difference is in how much manual work each one requires.

4. How to get ready in time

1. Check your software: Make sure your invoicing tool will support Verifactu (QR and trace code). Companies must be ready by 1 July 2026; autónomos by 1 July 2027.
2. Test early: Try AEAT's free app or another Verifactu-ready program to learn the process.
3. Keep invoices safe: You must store each one exactly as sent - no edits allowed.
4. Update your workflow: Every invoice must include the QR and a note confirming it was created through a Verifactu system.
5. Start early: Waiting until your deadline could cause rejections or technical issues.

Preparing now will make the transition smooth and stress-free.
