About Cerfa forms
These documents are typically required by entrepreneurs, legal representatives, and individuals navigating French bureaucracy. For instance, a new business owner might need to file a Form 1447-C-SD to declare their initial business property tax (CFE) liability, while an established company might use a Form M2 to report a change in management, address, or capital to the Registry of Commerce and Companies. These forms act as the primary communication channel between your entity and the French tax authorities or the commercial court.

How to Choose the Right Form
Navigating the French administrative system requires the correct "Cerfa" document for your specific situation. Whether you are launching a new activity or updating your company’s legal structure, choosing the right form ensures compliance with either the tax office (SIE) or the Registry of Commerce (RCS).
For New Businesses and Tax Setup
If you have recently created a company or opened a new secondary establishment, you must focus on your local business tax obligations.
- Formulaire n° 1447-C-SD (Cerfa n° 14187*16): Choose this form for your Initial Declaration of Cotisation Foncière des Entreprises (CFE). It is a mandatory filing used to identify your business premises, describe your activity, and declare the assets used by your new establishment. This is essential for the tax administration to calculate your CFE base for the 2026 tax year. It must be submitted to your Service des Impôts des Entreprises (SIE) following any new setup in 2025.
For Changes to an Existing Legal Entity
If your company is already established but has undergone significant structural or operational changes, you are required to update the public records to remain legally compliant.
- Formulaire M2 - Déclaration de modification (Cerfa 11682*07): Select this form to report major modifications to a legal person (such as a SAS, SARL, or SCI). This is the correct choice if you are changing your company name, moving your registered office, increasing your share capital, or replacing a manager or director. It serves as the official update for the Registry of Commerce and Companies (RCS).
Quick Selection Tips
- Choose Form 1447-C-SD if you are a new business owner setting up your first office or shop and need to register for local property taxes.
- Choose Form M2 if your business already exists but you have changed its name, address, or leadership structure.

Tips for Cerfa forms
French administrative forms are frequently updated, indicated by the number following the asterisk in the Cerfa code. Always ensure you are using the latest version, such as Cerfa 14187*16, to prevent the administration from rejecting your submission due to obsolete formatting.
Most business-related Cerfa forms, including the M2 and CFE declarations, require your 9-digit SIREN or 14-digit SIRET number. Double-check these against your official Kbis or INSEE records, as a single digit error can lead to significant delays in processing your file.
Manually filling out complex administrative paperwork is a common source of errors and frustration. AI-powered tools like Instafill.ai can complete these forms in under 30 seconds with high accuracy, ensuring your data stays secure during the process while saving you hours of manual entry.
Different Cerfa forms must be submitted to different authorities; for example, the 1447-C-SD is sent to the Service des Impôts des Entreprises (SIE), while modification forms are often routed through the Guichet Unique. Confirm the specific destination for your form to avoid your application being lost between departments.
Forms like the CFE declaration often contain specific sections for tax exemptions or 'exonérations' that you must manually tick to claim. Review these sections carefully before finalizing your form, as the administration will not necessarily apply these benefits automatically if they are left blank.
A Cerfa form is rarely submitted alone and usually requires supporting evidence like updated statutes, identity proofs, or lease agreements. Consult the 'notice' or instruction leaflet for your specific form number to ensure your dossier is complete, preventing the need for follow-up correspondence.
