On July 9, Law 11/2021 on measures to prevent and fight tax fraud was approved, transposing Directive (EU) 2016/1164, of the Council, of July 12, 2016, which establishes regulations against tax avoidance practices that directly affect the functioning of the internal market, modification of various tax regulations and in matters of gambling regulation (hereinafter, “Law 11/2021”).

One of the regulations approved by Law 11/2021 that has caused the most uproar is the prohibition established in it in relation to computer or electronic systems that support accounting or business management processes.

In particular, the development, commercialization and possession of computer programs and systems that allow the manipulation of accounting and management data is prohibited; forcing the integrity, conservation, accessibility, legibility, traceability and inalterability of the records.

Likewise, the possibility is foreseen that said Development Regulation may require the certification of the systems and that they use standard formats to ensure the legibility of the records and data…

This obligation came into force on October 11, 2021, despite the fact that – as the AEAT itself has clarified in note published in its electronic headquarters on the same date – it will be necessary to wait for the regulatory development to know in detail the requirements that the computer programs and systems must meet as well as, where appropriate, the way to certify or accredit that said requirements are met .

A sanctioning regime is also added that differentiates between the manufacture and marketing of this type of system and the use made of them by companies and users. In relation to manufacturing and distribution, the production and marketing of computer systems and programs is sanctioned when:

  1. allow parallel accounting;
  2. allow not to reflect, totally or partially, the annotation of transactions carried out;
  3. allow recording transactions other than the entries made;
  4. allow altering transactions already registered in breach of applicable regulations;
  5. do not comply with the technical specifications that guarantee the integrity, conservation, accessibility, legibility, traceability and inalterability of the records, as well as their legibility by the competent bodies of the Tax Administration, in the terms provided in the Law;
  6. The manufactured, produced or marketed systems are not certified, being obliged to do so by regulatory provision.
