Workplace accident declaration (DAT, Cerfa 14463)

The workplace accident declaration (Déclaration d'accident du travail, or DAT — Cerfa 14463*03) is the mandatory form through which a French employer notifies the relevant primary health insurance fund (Caisse Primaire d'Assurance Maladie, or CPAM) of any accident suffered by an employee in the course of, or in connection with, their work — including commuting accidents. Under Article R441-3 of the French Social Security Code (Code de la sécurité sociale), the employer must file the declaration within 48 hours of becoming aware of the accident, excluding Sundays and public holidays. The injured employee, for their part, has 24 hours to notify their employer. At the same time, the employer must hand the employee an accident treatment voucher (feuille d'accident — S6201, Cerfa 11383*03), which entitles them to receive all accident-related medical care with no upfront payment (tiers payant intégral — full third-party billing at doctors, pharmacies, and hospitals).

Deadlines

48 hours
Deadline to file with the CPAM, excluding Sundays and public holidays. It runs from the employer's KNOWLEDGE of the accident, not from its occurrence (CSS art. R441-3).
10 clear days
Window to attach reasoned objections, which oblige the CPAM to run a contradictory investigation (CSS art. R441-6).
Immediately
Hand the injured employee the accident voucher S6201, which entitles them to care with no upfront payment.

Documents to prepare

  • Initial medical certificate
  • Detailed account: place, time, witnesses, exact circumstances
  • Written witness statements, where any exist
  • The employee's last three payslips
  • Written record of the date the employee notified the employer

What this page gives you

The guide above and the link to the official site. ActioFin does not produce any document for this page: whatever you fill in or file is done on the official medium.

Who this applies to

  • Any employer informed of an accident suffered by an employee in or in connection with work, commuting accidents included
  • An employer who DISPUTES the work-related nature must still file: reasoned objections are added afterwards, they never replace the declaration
  • The employee has 24 hours to notify their employer — that notification is what starts the 48-hour clock

Worked example

A back strain lifting a pallet, filed the next day

A warehouse operative at KSM Logistics strains his back lifting a pallet on a Monday at 9 a.m. and notifies his line manager within the hour. The employer immediately issues him the accident treatment voucher S6201 (Cerfa 11383*03) and files the DAT online via net-entreprises.fr the following Tuesday — well within the 48-hour limit set by Article R441-3 CSS. Given that the employee had a prior history of lower-back problems, the employer submits written, reasoned objections (réserves motivées) within the 10-clear-day window (Article R441-6 CSS), which obliges the CPAM to conduct a full contradictory investigation before recognising the accident as work-related and triggering daily allowance payments.

How to fill it in, step by step

  1. Gather information from the employee within 24 hours: full identity, date, time, precise location, detailed circumstances, nature and anatomical site of injuries, any witnesses present, and any responsible third party.
  2. Complete Cerfa 14463*03 (or use the net-entreprises.fr online service): include your establishment details, SIRET number, the CPAM to which the employee is affiliated, and an objective factual account of the accident.
  3. Issue the accident treatment voucher S6201 (Cerfa 11383*03) to the injured employee without delay, so they can access all accident-related medical care at no upfront cost from the moment of the accident.
  4. Transmit the DAT to the CPAM within 48 hours (excluding Sundays and public holidays), and — if you intend to contest the occupational nature of the accident — attach or separately file written, reasoned objections within 10 clear days (Article R441-6 of the Social Security Code).
  5. Prepare the salary certificate (attestation de salaire — S6202) to enable the CPAM to calculate and pay the employee's daily allowances (indemnités journalières) starting from the first day of the work stoppage.

The form, line by line

Employer and establishment
Establishment details, SIRET number and the victim's primary health insurance fund: the declaration is sent to that fund.
Circumstances of the accident
Date, time, precise place, objective description of the facts, nature and location of injuries, any witnesses and liable third party — collected from the employee within 24 hours.
Reasoned reservations
An employer disputing the occupational nature still declares, and states reasoned reservations within 10 clear days (article R441-6 of the social security code).
Copies
Four copies: three sent to the primary fund by registered letter with acknowledgement of receipt within 48 hours, the fourth kept for five years; the declaration can also be made online.

Good to know

  • The 48-hour clock starts when the employer learns of the accident — not when it occurred. Keep a written record (email, log entry) of exactly when the employee notified you; this secures the filing deadline if it is ever disputed.

Common mistakes

  • Always file the DAT even if you believe the accident is not genuinely work-related. The declaration is mandatory; reasoned objections (réserves motivées) can be added within 10 clear days under Article R441-6 CSS. Objections never substitute for filing.
  • Filing late or not at all is a 4th-class contravention: up to €3,750 for a legal entity (Article R471-3 CSS), plus potential CPAM cost recovery. Always use the current Cerfa version (14463*03) to avoid form rejection.
  • Assuming some employees fall outside the obligation: the DAT is due for every employee, wherever they work (remote work, business travel) and whatever their contract (permanent, fixed-term, apprenticeship). A commuting accident calls for the same steps, and an injured intern is declared by the host organisation, which sends a copy to the intern's school without delay.
  • Forgetting the labour inspectorate after a fatal accident: the employer must inform it no later than 12 hours after the death, by a means that proves the sending date (email, registered letter). Failing that, the fine is €1,500 for an individual and €7,500 for a legal entity — the DAT sent to the CPAM does not replace this notice.
  • Letting the employee return without a return-to-work medical visit after a long absence: from 30 days off work for an occupational accident, the employer must arrange it. The accident also requires updating the occupational risk assessment document (DUERP).

Frequently asked questions

What is the deadline to report a workplace accident to the CPAM?

The employer has 48 hours — excluding Sundays and public holidays — from the moment they learn of the accident to file the DAT, as required by Article R441-3 of the French Social Security Code. The employee must notify their employer within 24 hours, except in cases of force majeure. The declaration can be submitted online via net-entreprises.fr or by sending the paper Cerfa 14463*03 directly to the competent CPAM.

What is the accident treatment voucher (feuille d'accident S6201) used for?

The accident treatment voucher (feuille d'accident — S6201, Cerfa 11383*03) must be issued by the employer to the injured employee immediately after the accident. It entitles the employee to 100% coverage of all accident-related medical costs — with no upfront payment — from doctors, pharmacists, or hospitals. The employee retains the voucher throughout their recovery and returns it to the CPAM once treatment is complete or the condition is stabilised (consolidation).

What penalties does an employer face for failing to declare a workplace accident?

Failing to declare, or declaring late, constitutes a 4th-class contravention (contravention de 4e classe) under Article R471-3 of the Social Security Code, which references Article 131-13 of the Penal Code: fines of up to €750 for an individual and €3,750 for a legal entity. Additionally, the CPAM may seek reimbursement from the employer for all costs incurred as a result of the accident.

Can the employer contest whether the accident is genuinely work-related?

Yes. The employer is still legally required to submit the DAT within 48 hours, but may attach — or subsequently submit — written, reasoned objections (réserves motivées) challenging the occupational nature of the accident within 10 clear days (10 jours francs) of the declaration, as provided by Article R441-6 of the Social Security Code. When such objections are filed, the CPAM must conduct a contradictory investigation before rendering its decision.

How do I file the workplace accident declaration online?

The DAT can be filed free of charge on net-entreprises.fr, in the section dedicated to workplace and commuting accident declarations. The online service mirrors all the fields of Cerfa 14463*03 — employee identity, circumstances, location, witnesses, and the nature and anatomical site of injuries — and transmits the completed form directly to the competent CPAM, generating an electronic acknowledgement of receipt.

Is there a waiting period before daily allowances are paid for workplace accidents?

No — unlike standard sick leave (which carries a 3-day waiting period), there is no waiting period (délai de carence) for workplace accidents. Daily allowances (indemnités journalières) are paid from the first day following the work stoppage; the day of the accident itself is borne by the employer. The rate is 60% of the daily reference salary (SJR) for the first 28 calendar days, then 80% from day 29. The SJR is capped at 1/30.42 of 83.4% of the monthly Social Security ceiling (PMSS — approximately €3,925/month in 2026).
