The world of archives is undergoing rapid changes, driven by regulatory and technological developments that are redefining professional practices. Between the extension of tax retention periods, the tightening of requirements for electronic archiving with probative value, and the arrival of artificial intelligence in the enhancement of heritage, archivists are facing structural changes that go far beyond the mere question of preservation.
Law of June 25, 2026 on tax fraud: what changes for archiving
The law no. 2026-534 of June 25, 2026 on combating tax fraud has modified a fundamental parameter for any organization managing archives: the legal retention period for tax documents is extended from 6 to 10 years. This new timeframe aligns with the maximum control period now available to the tax administration.
Specifically, the extension to 10 years applies to all documents whose retention period has not expired as of January 1, 2027. This means that businesses and individuals cannot simply update their archiving policy for documents created after this date. Existing archives are also affected.
This extension has direct consequences on storage volumes, whether physical or digital. For organizations managing significant collections, this represents several additional years of documents to retain, index, and make accessible in case of an audit. Following recent articles from Les Archivistes allows one to gauge the extent of these adjustments over the months.
Electronic archiving with probative value: the NF Z42-013 standard at the center of the game
Electronic archiving is no longer just about storing a PDF file on a server. Since 2025-2026, requirements have tightened around a specific concept: probative value. For a digital document to be admissible in court, the system that stores it must guarantee three things.
- The integrity of the document: no modifications should be possible after submission, and any attempt must be detectable by cryptographic mechanisms
- The identification of the author: the system must reliably link each document to its issuer, which often involves using a qualified electronic signature
- Complete traceability of operations: every consultation, every transfer, every action on the document must be logged and timestamped
The NF Z42-013 standard governs these requirements for electronic archiving systems. For digital vaults, the NF Z42-020 standard applies. These frameworks are not new, but compliance is becoming a direct operational issue with the generalization of electronic invoicing and dematerialized administrative procedures.
A gap between available online content and the reality on the ground
Search results on the topic of archives remain heavily focused on historical heritage and old press. Issues of regulatory archiving and digital compliance are rarely covered by mainstream media. Field feedback varies on this point: some organizations have already brought their systems into compliance, while others discover these obligations during an audit or litigation.
Artificial intelligence and heritage archives in France
Artificial intelligence has begun to transform how archival collections are enhanced and disseminated. Several French institutions are experimenting with AI tools for tasks that previously required considerable time.
Automatic handwriting recognition (HTR, for Handwritten Text Recognition) allows for the transcription of ancient documents on a scale that would be impossible manually. Entire collections of correspondence, parish registers, or notarial minutes thus become searchable in full text.
AI is also used to enrich metadata: automatic identification of places, people, and dates mentioned in a document. This fine indexing opens up possibilities for cross-research between collections that were previously siloed.
Current limitations of these tools
The available data does not allow for conclusions about the large-scale reliability of these technologies applied to archives. Error rates vary significantly depending on the quality of source documents, the type of writing, and the language. An 18th-century register in good condition does not present the same issues as a 15th-century notarial act with faded ink.
The question of human supervision remains open. An archivist is still necessary to validate automatic transcriptions and correct interpretation errors, which puts into perspective the productivity gains claimed by some software publishers.
Electronic invoicing and automated archiving: a convergence in progress
The gradual generalization of electronic invoicing in France creates a massive flow of natively digital documents that must be archived in accordance with current standards. This obligation does not only concern large companies: SMEs and freelancers are gradually being integrated into the system.
The stakes are twofold. On one hand, the archiving of electronic invoices is tending to automate through partner dematerialization platforms (PDP). On the other hand, this automation does not exempt the need to verify that the system used complies with the probative value requirements described above.
- Invoices must be retained in their original format, without conversion that would alter their integrity
- The archiving system must be distinct from the accounting management system to ensure the independence of evidence
- Retention periods must incorporate the new 10-year period introduced by the June 2026 law
For organizations managing both historical paper archives and growing digital flows, the coexistence of these two worlds raises organizational and skill-related questions that the profession of archivist now fully integrates.
The world of archives in 2026 stands at the crossroads of tax law, technology, and heritage. Professionals who follow these developments know that the next step, with the effective application of the 10-year period on January 1, 2027, will impose concrete decisions on tools, budgets, and working methods.
