Changes to self-employed invoices

rules governing self-employed billing programs establishes a number of technical and safety requirements. To be considered valid, these systems must ensure consistency and traceability of account records. This means that every transaction must be protected from any modification attempts, either by the user or by external elements. The law also requires the program to maintain an event log that documents all interactions performed on the system, from the beginning to the completion of each operation.

In addition, the order clarifies the need systems generate an immediate account record with detailed information for each operation. This includes The issuer’s tax identification number (NIF), a general description of the transaction, and the type of invoice issued.. Likewise, records must be chained together using a technique known as “hash”, which creates a unique fingerprint for each account. Any change to a previous document will change the traces of subsequent entries, thereby ensuring the authenticity of the account history. Another important aspect is the electronic signature confirming transactions, although this will not be mandatory in cases where data is voluntarily submitted to the Tax Authority.

One of the elements introduced in the new rules is a system known as Veri*factu. This system allows self-employed workers and companies to automatically send their bills to the Treasurya move designed to simplify tax transparency and reduce fraud. Although some billing programs allow enable or disable this featurebusinesses will be able to choose whether they want to send their bills to the Treasury or not. Those who choose to do so will comply with Verifactu’s system, and those who choose not to provide information will be considered **Non-Verifactu**.

For self-employed workers, this flexibility can be a relief as it allows them to choose between keeping their records confidential or voluntarily submitting them to the tax administration. However, it is important to remember that in both cases the program must comply with established rules and ensure that All records are properly protected and certified.

Time frame for adaptation to new rules

Although the Anti-Fraud Act initially mandated that all billing systems must comply with regulations by July 2025, Sources in the tax department noted that an extension of the deadline is possible. This will allow software developers to adapt their products to new requirements and give freelancers enough time to make the necessary changes without any penalties.

Currently the official dates are:

• lSoftware makers have until July 2025. to certify your billing programs.
• From this date, self-employed workers must update their systems. or have software that meets the requirements of the new ministerial order.

Since non-compliance can result in significant penalties, freelancers should be aware of any changes to deadlines as The Ministry of Finance may extend the adaptation period until the end of 2025 or even the beginning of 2026.depending on the time it takes software developers and users to implement changes.

Responsibility and sanctions for freelancers and developers

The responsibility for complying with these rules does not fall solely on the self-employed. The law requires both software developers and marketers to ensure that their products meet all applicable requirements. With regard to the self-employed and their accounts, the General Tax Law states that using billing programs that are not properly certified or that have been modified is an offense and may result in sanctions up to 50,000 euros.
