France Single-Shareholder Company Formation (SASU or EURL)

Prepare the data to form a French single-shareholder limited-liability company — either a Société par Actions Simplifiée Unipersonnelle (SASU) or an Entreprise Unipersonnelle à Responsabilité Limitée (EURL, the single-member variant of the SARL) — and file the declaration of constitution via the Guichet unique des formalités d'entreprises operated by INPI, the sole mandatory entry point for company creation since 1 January 2023. This is the 'LLC' analogue France was missing in the Business Formation vertical alongside de/handelsregister/gmbh-formation-musterprotokoll, gb/companies-house/company-incorporation-in01, ie/cro/company-incorporation, and us/ca/sos/business-entity-llc-formation — fr/inpi/micro-entrepreneur-activity-declaration covers only the micro-entrepreneur sole-trader regime, not a true limited-liability company. Scoped to a brand-new company (not a takeover/purchase of an existing fonds de commerce) with a single natural-person founder who is also its sole managing officer (président for a SASU, gérant for an EURL) — the maximum single-founder shape common to both legal forms. Out of scope: multi-shareholder SAS/SARL, a legal-person (rather than natural-person) sole shareholder, the EIRL status (superseded for new registrations by the 2022 entrepreneur individuel reform), agricultural/liberal-profession company forms (GAEC, SCP, SEL...), and take-over of a pre-existing fonds de commerce (achat/apport/location-gérance). It does not submit anything or imply government endorsement.

Field reference

35 fields across 7 steps, read from the published schema.json, with names, types, requiredness, and validation as the document states them. The live government form remains the authoritative source.

Share capital

  • shareCapitalAmountEur number required

    Both SAS/SASU (Code de commerce art. L227-1) and SARL/EURL (art. L223-2) have had no statutory minimum share capital since the 2003 Loi pour l'initiative économique; the amount is freely fixed in the statuts (in practice as low as EUR 1).

    range: 1–∞
  • capitalIsVariable boolean required

    Variable-capital clause (capital variable)

  • capitalVariableMinimumEur number optional

    The statutory floor below which the variable share capital may not be reduced.

    range: 0–∞

Registered office

  • registeredOfficeAddressLine string required

    Registered office address (Adresse du siège)

    length: 1–300
  • registeredOfficePostalCode string required

    Registered office — postal code

    pattern
  • registeredOfficeCommune string required

    Registered office — commune

    length: 1–100
  • registeredOfficeArrangement enum required

    own_or_leased_premises = ordinary commercial or owned/leased premises (the default; no special notation on the form). legal_representative_home_provisional = the company is provisionally domiciled at the managing officer's home. domiciliation_company = the company is domiciled with a registered domiciliation-service provider (gates domiciliationCompanyIdentificationNumber/domiciliationCompanyName).

    enum: own_or_leased_premises | legal_representative_home_provisional | domiciliation_company
  • domiciliationCompanyIdentificationNumber string optional

    Domiciliation provider's unique identification number

    length: 1–50
  • domiciliationCompanyName string optional

    Domiciliation provider's name

    length: 1–200

Sole shareholder

  • soleShareholderFullName string required

    Scoped to a natural-person sole shareholder (a legal-person sole shareholder is out of scope for this document).

    length: 1–200classification: pii
  • soleShareholderUsualName string optional

    Sole shareholder's usual/married name (Nom d'usage), if different

    length: 0–200classification: pii
  • soleShareholderDateOfBirth date required

    Sole shareholder's date of birth

    classification: pii
  • soleShareholderPlaceOfBirth string required

    Sole shareholder's place of birth

    length: 1–200classification: pii
  • soleShareholderNationality string required

    Sole shareholder's nationality

    length: 1–100classification: pii
  • soleShareholderResidentialAddress string required

    Sole shareholder's residential address

    length: 1–300classification: pii

Managing officer (président / gérant)

  • managingOfficerIsSoleShareholder boolean required

    The managing officer is the président for a SASU or the gérant for an EURL. Both source forms model this as a fixed checkbox (SASU: 'l'associé unique en est le président'; EURL cover note: officers who are also the sole shareholder complete an additional social-status cadre), implying the common case is a single natural person acting as both. When false, officerFullName and its siblings identify a distinct managing officer.

  • officerFullName string optional

    Managing officer's name at birth

    length: 1–200classification: pii
  • officerDateOfBirth date optional

    Managing officer's date of birth

    classification: pii
  • officerNationality string optional

    Managing officer's nationality

    length: 1–100classification: pii
  • officerResidentialAddress string optional

    Managing officer's residential address

    length: 1–300classification: pii
  • managerSpouseWorksInBusiness boolean optional

    This question is printed only on the SARL/EURL declaration, not on the SAS/SASU one — an EURL gérant who is also the sole shareholder is by definition a majority (in fact, sole) manager, so the 'collaborateur' status is always available to a working spouse here (unlike a minority-manager SARL, out of scope for this single-shareholder document).

  • managerSpouseStatus enum optional

    salaried = SALARIE (employee); associate = ASSOCIE (the spouse becomes a shareholder/partner in the company; since the gérant here is always majoritaire, this triggers a separate TNS social-status filing, out of scope here); collaborator = COLLABORATEUR (collaborating-spouse status, available because the gérant here is always a sole/majority manager).

    enum: salaried | associate | collaborator

Activity and tax elections

  • activityStartDate date required

    Activity start date

  • activityType enum required

    Activity type

    enum: permanent | seasonal | ambulant
  • financialYearEndDate string required

    The recurring calendar day/month the company's financial year closes each year, e.g. '12-31' for a calendar-year exercise.

    pattern
  • firstFinancialYearEndDate date optional

    First financial year's closing date, if different

  • incomeTaxRegime enum required

    corporate_is = Impôt sur les Sociétés (the default for a SAS/SASU; an EURL with a natural-person sole shareholder may elect it). flow_through_partnership_regime = régime des sociétés de personnes (the default for an EURL with a natural-person sole shareholder — profits taxed directly in the shareholder's own income tax; a SAS/SASU may elect it only in the narrow circumstances printed in the form's own 'OPTIONS PARTICULIERES' cadre, out of scope to enumerate further here).

    enum: corporate_is | flow_through_partnership_regime
  • vatRegime enum required

    VAT (TVA) regime

    enum: franchise_en_base | reel_simplifie | mini_reel | reel_normal

Declaration and filing

  • declarationPlace string required

    Place of declaration (Fait à)

    length: 1–100
  • declarationDate date required

    Date of declaration

    classification: pii

Verification record

This file is the source-review record for this document version, per the manual-source-review-v1 practice.

Current claim

  • status: draft
  • verification.method: manual-source-review-v1
  • verification.lastVerifiedAt: 2026-07-04

The document was derived from and cross-checked against the sources below. The Guichet unique's own live declaration wizard sits behind an authenticated INPI Connect/FranceConnect+ account this review could not reach, so the practice's field-by-field comparison against a live screen set has not been completed — status remains draft, not verified, the same honest limitation recorded for the sibling fr/inpi/micro-entrepreneur-activity-declaration.

Why this schema and why now (GOV-1143)

GOV-1143 asked for a fresh GovSchema Standard Research cycle: catalog what exists, research a missing government process, document its fields, test-run it with mock data, and author it into the registry. Step 1 (catalog audit) found discovery/catalog.json already carries three open Business Formation candidates filed by the prior GOV-1136 cycle — fr/inpi/sasu-or-eurl-formation, nl/kvk/bv-formation, and sg/acra/private-limited-company-incorporation — each an open sibling gap left after that cycle authored de/handelsregister/gmbh-formation-musterprotokoll, Germany's true limited-liability-company formation schema. This document closes the French sibling: fr/inpi/micro-entrepreneur-activity-declaration (already published) covers only the micro-entrepreneur sole-trader regime, not a company with separate legal personality — the "LLC" analogue France was still missing, alongside gb/companies-house/company-incorporation-in01, ie/cro/company-incorporation, ca/on/registration/business-incorporation, nz/companiesoffice/company-incorporation, in/mca/company-incorporation-spice-plus, us/ca/sos/business-entity-llc-formation, and au/asic/proprietary-company-registration.

Sources examined

  • Document (id, version): fr/inpi/sasu-or-eurl-formation / 1.0.0
  • Spec version: GovSchema 0.3.0
  • Authority: INPI (Institut National de la Propriété Industrielle), operator of the Guichet unique des formalités d'entreprises (formalites.entreprises.gouv.fr / procedures.inpi.fr), the sole mandatory entry point for company-creation formalities in France since 1 January 2023 (exclusively since 1 January 2025), which superseded the prior form-specific Centre de Formalités des Entreprises (CFE) network.
  • Live process guidance, fetched 2026-07-04:
  • Primary form sources (both retired since the Guichet unique went exclusive, but still hosted as fillable AcroForm PDFs and used here as a field-set proxy for the modern online declaration — the exact technique used for the sibling fr/inpi/micro-entrepreneur-activity-declaration):
    • Cerfa **13959\*05**, "M0 SAS — Déclaration de création d'une société ou autre personne morale", retrieved directly from a Greffe du tribunal de commerce mirror (greffe-tae-paris.fr), 4 pages (2 pages × 2 duplicate copies).
    • Cerfa **11680\*06**, "M0 SARL — Déclaration de constitution d'une société à responsabilité limitée (SARL, SELARL y compris à associé unique)", retrieved from a third-party fillable-form mirror (cerfa.vos-demarches.com), 4 pages (2 pages × 2 duplicate copies).
    • PDF extraction method: both PDFs carry genuine fillable AcroForm layers with real printed text underneath. pdfjs-dist's getTextContent() returned the full instructional/cadre text of every page; getAnnotations()/getFieldObjects() independently returned each fillable field's internal name (e.g. DENOMINATION 1, Capital montant unité monétaire, AVEZ-VOUS UN CONJOINT MARIE OU PACSE), corroborating the cadre-text extraction. Both forms' 4 pages are two duplicate copies of the same 2-page declaration, confirmed by identical field names recurring across pages 1–2 and 3–4 — the same duplicate-copy layout already documented for the sibling micro-entrepreneur Cerfa.
  • Retrieved / reviewed: 2026-07-04 (all sources fetched and read live at authoring time; no bot-block encountered on any of the above domains — unlike the Guichet unique's own authenticated wizard).
  • Reviewer: GovSchema Engineering (Standards Engineer, initial authoring source-review).

Conformance test run

Two scenarios exercise both legalForm branches and every conditional field:

  • conformance/fr/inpi/sasu-or-eurl-formation/1.0.0/application-packet-sasu.json — a single founder forming a SASU, themself the président (managingOfficerIsSoleShareholder = true), ordinary leased premises, fixed EUR 1 capital, corporate IS / franchise en base elections.
  • .../application-packet-eurl.json — a sole shareholder forming an EURL with a distinct gérant (managingOfficerIsSoleShareholder = false), a variable-capital clause (capitalIsVariable = true, capitalVariableMinimumEur = 2000), a domiciliation-company registered office, a working PACS partner (managerSpouseWorksInBusiness = true, managerSpouseStatus = collaborator), and the flow-through partnership / réel simplifié tax elections.

A scripted evaluator (reimplementing the GSP-0013 requiredWhen grammar — conditionLeaf operators plus all/any/not composition — against fields[] static required and documents[].requiredWhen) checked both packets: 0 violations across 35 fields + 6 documents each. A mutation test confirmed the conditional requirements actually fire, not just that the happy path passes: removing capitalVariableMinimumEur and managerSpouseStatus from the EURL packet while capitalIsVariable and managerSpouseWorksInBusiness stayed true correctly reintroduced exactly those two violations.

Full console output is saved as application-packet-sasu.txt and application-packet-eurl.txt alongside the packets.

What was NOT modeled, and why

  • Multi-shareholder SAS/SARL. Both source Cerfa forms and the underlying law support any number of shareholders; this document scopes to the single-shareholder case only, matching the single-founder scope every other company-formation schema in this registry (DE, GB, IE, CA/ON, NZ, IN, US-CA, AU) already uses.
  • Legal-person sole shareholder. Both cerfas print a "POUR UNE PERSONNE MORALE — forme juridique / Lieu et N° d'immatriculation" branch for a corporate shareholder; out of scope here, which assumes a natural person.
  • EIRL status. Superseded for new registrations by the unified 2022 entrepreneur individuel reform (automatic patrimoine separation without an EIRL election), the same scoping decision already recorded for the sibling fr/inpi/micro-entrepreneur-activity-declaration.
  • Agricultural and liberal-profession company forms (GIE/GEIE, sociétés civiles, SEL/SELARL/SELAFA, agricultural activity). Cerfa 11680\*06's own cover explicitly excludes agricultural-activity SARLs from its scope, and both forms flag SEL variants as printed but out-of-scope for this document's plain SASU/EURL case.
  • Take-over of a pre-existing fonds de commerce (achat/apport/location- gérance/gérance-mandat, "ORIGINE DU FONDS"). Both Cerfas devote a whole cadre to a business-transfer origin; this document scopes to a brand-new-activity creation only ("Création, passer au cadre …" branch), the same "création" vs. "reprise" scoping boundary other registration schemas in this registry already draw.
  • Establishment address distinct from the registered office ("ADRESSE DE L'ETABLISSEMENT où s'exerce l'activité, si différente du siège"). Both Cerfas make this genuinely optional; deferred to keep the single-address common case tractable, to be added as a future MINOR if requested.
  • The live Guichet unique wizard's own screen order and exact field labels. Blocked behind an authenticated INPI Connect/FranceConnect+ session; this version relies on the retired Cerfas as a field-set proxy, the same limitation already disclosed for the sibling schema.
