VeriFactu 2027: Why 2026 Is the Critical Year for Your Accounting Infrastructure

In the coming months, many companies in Spain will need to make important decisions regarding their billing system and accounting infrastructure. The reason is the implementation of the VeriFactu system, driven by the Anti-Fraud Law and regulated by Royal Decree 1007/2023.

Although many perceive it as a change arriving in 2027, the reality is different: 2026 will be the decisive year to prepare companies’ accounting infrastructure.

Organizations that wait until the last minute will likely face urgent technological changes, adjustments to their accounting processes, and adaptations in their billing software.

In this article, we analyze why 2026 will be the key year to get ahead of VeriFactu and how to prepare properly.

What is VeriFactu and what changes for companies

VeriFactu is a system that allows billing records to be automatically sent to the Spanish Tax Agency (Agencia Estatal de Administración Tributaria) directly from billing software.

Its goal is to strengthen fiscal control and prevent manipulation of accounting records.

This means that billing programs must:

• Ensure the integrity and traceability of invoices
• Prevent alteration or deletion of records
• Generate verifiable records
• Allow automatic data submission to the Tax Agency

In practice, this means that companies will need to review their billing software and the architecture of their accounting systems.

Why 2026 will be the decisive year

Although full implementation is set for 2027, waiting until then can be a strategic mistake. Here are the reasons:

1. Adapting accounting software takes time

Adapting to VeriFactu is not just about updating a program.

In many organizations, it involves:

• Changing billing software
• Integrating management systems (ERP, CRM) with new accounting solutions
• Adjusting invoice validation workflows
• Reviewing archiving and audit systems

In companies with complex systems, this process can take months.

2. Technology providers will face massive demand

As the deadline approaches, thousands of companies will simultaneously seek to:

• Update software
• Migrate systems
• Validate certified solutions

This can create bottlenecks with technology providers and specialized consultants.

Preparing during 2026 will allow avoiding delays and rushed decisions.

3. Accounting digitalization is no longer optional

VeriFactu is part of a broader fiscal digitalization process already seen in Europe.

In Spain, systems like:

• Immediate Information Supply (SII)
• Mandatory electronic invoicing under the Crea y Crece Law

already exist. In this context, companies need more connected, automated, and traceable accounting infrastructures.

4. It can affect internal control processes

VeriFactu does not only impact technology. It also affects:

• Internal billing processes
• Internal control and accounting validation
• Document management and record archiving

This implies that financial and administrative teams must adapt their procedures.

Signs your company should start preparing now

If your company is in any of these situations, it is advisable to start reviewing your infrastructure in 2026:

• You use outdated billing software
• Your billing is managed with poorly integrated systems
• You work with multiple accounting programs
• Your company has a high volume of invoices

The more complex the current system, the more important it is to get ahead.

Frequently asked questions about VeriFactu

Will all companies need to adapt?

Yes. The regulation will affect most companies and freelancers issuing invoices in Spain, with only very specific exceptions.

Will it be mandatory to send all invoices to the Tax Agency?

The system allows two modes:

• VeriFactu Systems, which automatically send records
• Verifiable Systems, which meet the requirements but do not send data automatically

Does it require changing software?

It depends on the program the company uses.

Some providers will update their solutions, but other systems may not be adaptable and will need to be replaced.
