The Countdown to VeriFactu Has Begun
As a foreign freelancer operating in Spain, keeping up with tax regulations is essential. As of September 2026, the most significant upcoming change is the definitive implementation of the VeriFactu system, a development that will transform how all sole traders and companies issue their invoices.
This new system, driven by the Anti-Fraud Law, aims to standardize invoicing and ensure the integrity of records by periodically sending information to the Spanish Tax Agency (AEAT). The goal is clear: to reduce tax fraud and the underground economy. For you, this means you must adapt your processes before the deadline.
Key Dates and How It Affects You
The rollout of VeriFactu is gradual, but the final deadlines are set and fast approaching:
- January 1, 2027: Mandatory for all companies and corporations.
- July 1, 2027: Mandatory for sole traders (autónomos) and micro-enterprises, regardless of their nationality, as long as they conduct their economic activity in Spanish territory.
This means that from July 1, 2027, you will no longer be able to issue invoices using tools like Word or Excel. You will be required to use invoicing software that meets VeriFactu's technical requirements. To better understand the system, you can check our complete guide on [What is VeriFactu?

Adapting Your Software and Invoicing Processes
The transition to VeriFactu is not just a software change; it involves a technological adaptation. If you use accounting software or an ERP, you must ensure it is compliant. Preparation is key, and many are already researching integración ERP VeriFactu or looking for a pasarela VeriFactu para software if they use custom-built solutions.
For those using popular programs, data migration is a central concern. Tasks like how to importar Factusol a VeriFactu, or transfer information from other platforms like Sage 50 or Holded, must be planned in advance. Even if your method was to importar Excel a VeriFactu using templates, this process will change radically, as the invoice must be generated directly from a certified system. You can find more details on the deadlines in our article on [VeriFactu 2027: Deadlines for Freelancers in Spain](/en/verifactu-2027-deadline).
While this invoicing change is significant, your quarterly tax obligations, such as VAT (Modelo 303) and Personal Income Tax (Modelo 130) returns, remain unchanged for now.
To avoid penalties and ensure a smooth transition, it is crucial to start preparing now. Solutions like Fakturia.es offer invoicing software fully adapted to VeriFactu and the Anti-Fraud Law, ensuring you comply with the regulations easily and securely from day one.
