SIPSI Registration Penalties — What Are the Risks for Employers?

Sending workers to France without a SIPSI declaration is one of the most common mistakes construction companies make. The consequences hit hard — financially and operationally. This article explains what fines apply and how to avoid them.

What is the SIPSI declaration?

SIPSI (Système d'Information sur le Détachement International) is the French Ministry of Labour's electronic system for registering posted workers. Every foreign company sending a worker to France — regardless of industry or headcount — must submit a SIPSI declaration before work begins.

Declarations are submitted through teleservice.travail.gouv.fr. The submission itself is free and electronic, but requires an account and familiarity with the French system.

How much is the fine for missing SIPSI?

The administrative fine for a missing SIPSI declaration can reach €4,000 per unregistered worker. For repeat offences within two years, the fine doubles to €8,000 per worker.

Example: a construction company with 10 workers and no SIPSI filings faces fines of up to €40,000. That is a real risk for any business.

Who enforces the fines?

Inspections are conducted by DREETS officers (Direction régionale de l'économie, de l'emploi, du travail et des solidarités) — France's equivalent of the Labour Inspectorate. Inspections happen directly on construction sites and worksites, often without advance notice.

What else can happen?

• Work stoppage — the inspector can order all work to halt until documentation is in order.
• Warning lists — companies that violate the rules can be placed on blacklists, making it harder to win public contracts.
• Client liability — the French client (e.g. main contractor) can be held jointly liable for a subcontractor's missing filings. This creates pressure from clients to verify documentation.

How to avoid the fine

The SIPSI declaration must be submitted before the worker's first day. Filing two to three days early leaves time to correct any errors.

Required information includes:

• Employer data (company name, tax ID, address, REGON)
• Worker data (name, date of birth, nationality)
• French client details
• Work dates and site address
• French representative details
