A startup's first employee: legal obligations and formalities

A startup's first employee: legal obligations and formalities (2026 guide)

Moving from solo founder to employer is a major structural step. This guide gives you a practical roadmap — without jargon — to hire your first employee in France in compliance with the Labour Code and social security bodies.

Before hiring: define the need and legal foundations

• Contract type (permanent, fixed-term, work-study, part-time, internship) and probationary periods according to role and applicable collective agreement. Useful references: Ministry of Labour.
• Pay at least at the statutory minimum wage (SMIC) or collective-agreement minimum, any bonuses, objectively measurable variable pay. Guidance on Service-Public.fr — official guidance.
• Working time (35 hours/week, maximum daily and weekly hours, rest, overtime): legal frameworks and exemptions on the Ministry of Labour website.
• Cost budget (salary + contributions + health insurance + protection insurance + tools). Simulations and support schemes from URSSAF — social contribution authority.

Step-by-step legal checklist

1) DPAE to URSSAF no later than 8 days before hiring

The Pre-hiring Declaration (Déclaration Préalable à l’Embauche, DPAE) is mandatory and a condition for lawful hiring. Submit it online through your employer account (URSSAF — social contribution authority). It enables, among other things, employee registration and notifies the relevant social security bodies.

• Deadline: no later than 8 days before the employee starts.
• Risk if omitted: possible classification as concealed employment (travail dissimulé) (see penalties below).

2) Join an occupational health service (SPSTI) and organise the visit

From the first employee, join an SPSTI (inter-company service). Organise the information and prevention visit (VIP) within 3 months of hiring (before assignment for hazardous roles, night work and minors). References: Ministry of Labour.

3) Open and maintain the single staff register (RUP)

Mandatory from the first employee and for each establishment. Record each arrival/departure chronologically (identity, job, contract type, dates, special authorisations).

• Retention: 5 years after the employee leaves.
• Framework and particulars: Mandatory business registers (Service-Public Pro).

4) Employment contract + mandatory employee information

A written document is strongly recommended for every permanent contract (CDI) and mandatory for fixed-term (CDD)/part-time contracts. Since implementation of Directive (EU) 2019/1152, employers must provide a core set of written information on the employment relationship within short periods (some within 7 days, the rest within 1 month). Legal basis: Labour Code (Legifrance) and EUR-Lex — EU law portal.

• Key particulars: parties' identities, hiring date, job/classification coefficient/location(s), collective agreement, pay (fixed/variable), working time and organisation, probationary period, applicable termination procedures, supplementary social protection.
• Useful startup clauses: confidentiality, intellectual property (software, inventions), non-compete (if legitimate/proportionate), remote work.

5) Health and safety: DUERP, prevention and employee information

• DUERP (single occupational risk assessment document) mandatory from the first employee. Update at least annually if you have at least 11 employees; otherwise upon any decision affecting health/safety conditions. References: Ministry of Labour.
• Mandatory information/notices (labour inspectorate, emergency assistance, safety instructions, equality, harassment), now possible “by any means”. Practical details on Service-Public.fr — official guidance.

6) Payroll, contributions and DSN

• Compliant payslip and salary payment on a fixed date. Correct handling of withholding tax, allowances and benefits.
• Monthly DSN (individualised social declaration) and contribution payments through URSSAF — social contribution authority.
• Supplementary pension: enrol the employee with an Agirc-Arrco fund through your payroll provider. Guidance on Service-Public.fr — official guidance.

7) Health insurance and protection insurance

• Mandatory collective supplementary health insurance from the first employee (minimum benefits package, employer funding ≥ 50%, founding instrument such as a unilateral employer decision or DUE). Information on Service-Public.fr — official guidance.
• Protection insurance (prévoyance): often mandatory for managerial staff (death cover) and, depending on collective agreements, for all. Check your national collective agreement (see Legifrance — French legislation portal).

8) HR data, tools and CNIL compliance

• Inform the employee about processing of their data (purposes, legal basis, duration, rights).
• Record of activities, data minimisation, security (limited payroll/HR access).
• Tools (time clocks, monitoring, BYOD): assess proportionality, update the DUERP and information notices. CNIL guide: cnil.fr — French data protection authority.

9) Intellectual property and innovation

In a startup, secure ownership of creations (code, databases, content, designs) through appropriate assignment clauses and contribution traceability. Employee inventions: statutory regimes and good practice presented by INPI — French industrial property office.

10) Common special cases

• Non-EU foreign employee: prior work authorisation and permit checks. Detailed procedures on Service-Public.fr — official guidance and the Ministry of Labour website.
• Alternative to hiring: umbrella employment (portage salarial) to test a need or outsource the legal employer role.
• Startup culture: HR good practice and key reminders from DRIEETS Île-de-France — regional labour authority.

Penalties and mistakes to avoid

• No DPAE: risk of concealed employment (up to 3 years' imprisonment and a €45,000 fine for an individual, €225,000 for a legal entity) — see the Labour Code and Ministry of Labour.
• Missing single staff register: fine (up to €750 per affected employee). Source: Service-Public Pro — business guidance.
• Absent or unmaintained DUERP: fifth-class offence (up to €1,500, €3,000 for repeat offences). Reference: Ministry of Labour.
• No collective health insurance scheme: risk of URSSAF reassessment and employment tribunal proceedings. Information on Service-Public.fr — official guidance and URSSAF — social contribution authority.

10-day roadmap for a first hire

• Day-10 to Day-8: choose contract and collective agreement, configure payroll, join SPSTI, prepare DUERP.
• Day-8: URSSAF DPAE.
• Day-7 to Day-1: finalise and sign the contract, open the RUP, establish health/protection insurance (DUE), prepare safety induction and mandatory information.
• Day 0: welcome, provide written information (core set within 7 days / 1 month), hand over tools, health and safety instructions, VIP schedule.
• Day+1 to Day+7: schedule VIP, complete written information, check health/protection insurance rights, test payroll.
