The start of the 2026 school year imposes a dense regulatory calendar on French financial departments. Between the implementation of mandatory electronic invoicing, the extension of the surtax on large companies’ profits, and a simplification law that redesigns administrative formalities, the decisions to be made are no longer a matter of strategic monitoring but of immediate compliance.
Electronic invoicing in France: the operational shock of September 1, 2026
The receipt of electronic invoices is mandatory for all VAT-registered businesses since September 1, 2026, including associations. Large companies and mid-sized enterprises must simultaneously issue their invoices in electronic format and transmit their e-reporting data via approved platforms.
SMEs, very small enterprises, and micro-enterprises benefit from a deferral until September 1, 2027 for the obligation to issue invoices. This delay does not exempt them from receiving invoices: every business must accept a dematerialized invoice from now on.
The issue is not so much the legal framework as the delay in deployment. According to Le Monde, nearly one in two affected companies has not yet started the necessary steps just days before the deadline. This figure reveals a lack of preparation that goes beyond mere negligence. Many organizations have not yet chosen a partner dematerialization platform (PDP), nor adapted their accounting chain.
We observe that companies acting on the business portal of Clarity News find regular updates on these regulatory deadlines and feedback on compliance implementation.
Financial departments that have not yet started this project must prioritize three points:
- Identifying an approved PDP compatible with their management software, knowing that technical connection times can take several weeks
- Updating client and supplier files (SIREN, routing addresses) to ensure proper receipt of flows
- Training accounting teams on new formats (Factur-X, UBL) and associated e-reporting obligations
Surtax on large companies’ profits: a measure that continues
The exceptional contribution on large companies’ profits, initially presented as temporary, is now confirmed in the French tax landscape. The draft finance law for 2027 provides for the return of this contribution, establishing a lasting tax pressure on groups whose turnover exceeds a certain threshold.
For mid-sized enterprises close to this threshold, the issue is no longer just accounting. It becomes strategic: certain external growth operations or intra-group restructuring change the consolidation scope and can push a company into the surtax’s application field.
Tax departments must integrate this contribution into their multi-year simulations, and not just into the current fiscal year’s budget. The signal sent by the legislator is one of a gradual normalization of the surtax, far from the exceptional nature initially claimed.
Simplification law for economic life: what changes concretely for SMEs
The simplification law for economic life, enacted in 2026, eliminates or reduces several dozen administrative formalities weighing on very small and small enterprises. The text is not limited to statements of intent: it modifies specific reporting obligations.
Among the most structuring measures, we note the reduction in the number of prior authorization regimes for certain regulated activities, the simplification of statutory modification procedures, and the easing of legal publication obligations in certain scenarios.
The real challenge remains the adoption by businesses. Legal simplification only has an effect if leaders and their advisors (lawyers, accountants) adapt their practices. Firms that support very small enterprises observe that many business leaders still ignore the formalities that have now been eliminated and continue to carry them out out of habit.
Promised tax stability for businesses: the Lescure pact
Roland Lescure has promised a stability pact for businesses, particularly concerning the research tax credit and the Dutreil pact. The stated goal is to provide investors and leaders with a predictable framework over several fiscal years.
This promise comes into direct tension with the extension of the surtax mentioned above. The coexistence of a discourse of stability and an actual tax burden increase creates uncertainty that financial markets and investment funds incorporate into their valuation models, particularly in the Paris market.
Interim management in France: a market that is structuring itself in response to regulatory urgencies
The use of interim management is increasing in French SMEs and mid-sized enterprises. It is no longer a reflex reserved for large groups in crisis situations. The regulatory deadlines of 2026 (electronic invoicing, CSRD for larger structures) create temporary needs for specialized skills that internal teams do not always possess.
The most requested interim missions concern financial management and information systems management, precisely the two functions most solicited by mandatory dematerialization and new reporting requirements.
The interim management market is professionalizing with the emergence of sectoral barometers and specialized firms that segment their offerings by company size. For SMEs, hiring an interim financial director for six to twelve months allows for the successful implementation of a compliance project without recruiting a permanent profile.
The start of the 2026 school year marks a turning point for French companies. The texts are published, the deadlines are set, and the delays accumulated by a significant part of the economic fabric turn every week of postponement into a risk of non-compliance. General management that has not yet prioritized their regulatory obligations is exposed to penalties, but also to a loss of competitiveness against competitors already operational in dematerialized invoicing.
