How to Calculate the Special Severance Indemnity for Work-Related Unfitness in France
When an employee is dismissed for work-related unfitness (inaptitude d’origine professionnelle — unfitness arising from a workplace accident or occupational illness), they are entitled to enhanced compensation under Article L.1226-14 of the French Labour Code. Yet calculation errors are frequent: doubling the wrong indemnity, forgetting to compare against the collective bargaining agreement, confusing the two amounts due, and so on. Here is the complete method to calculate correctly.
Table of Severance Indemnities for Unfitness
The amount depends on the origin of the unfitness. An overview before going into detail:
| Item | Non-work-related unfitness | Work-related unfitness (workplace accident / occupational illness) |
|---|---|---|
| Severance indemnity | Statutory indemnity (Art. L.1234-9), or the contractual/collective-agreement indemnity if more favourable | Special indemnity = double the statutory indemnity (Art. L.1226-14); the collective-agreement indemnity is not doubled |
| Notice period | Not performed; no compensatory indemnity in lieu of notice, but the notice period is taken into account when calculating the severance indemnity (Art. L.1226-4) | An indemnity equal to the compensatory indemnity in lieu of notice (Art. L.1226-14, referring to L.1234-5), due even if the notice is not performed |
| Legal basis | Art. L.1226-4 | Art. L.1226-14 |
The remainder of this article details the calculation for work-related unfitness — the situation most prone to errors.
What Does Article L.1226-14 of the French Labour Code Provide?
Article L.1226-14 provides that an employee dismissed for work-related unfitness is entitled to two distinct indemnities:
- A termination indemnity equal in amount to the compensatory indemnity in lieu of notice (Article L.1234-5).
- A special severance indemnity equal to double the statutory severance indemnity (Article L.1234-9), unless more favourable provisions apply under the collective bargaining agreement.
Here is the exact wording: “Termination of the employment contract in the cases provided for in the second paragraph of Article L.1226-12 entitles the employee to a compensatory indemnity equal in amount to the compensatory indemnity in lieu of notice provided for in Article L.1234-5, as well as to a special severance indemnity which, unless more favourable provisions apply under the collective bargaining agreement, is equal to double the indemnity provided for in Article L.1234-9.”
It is imperative to clearly distinguish these two amounts: they have different legal natures, different calculation bases, and different social security and tax treatments.
How to Calculate the Special Severance Indemnity?
Step 1: Calculate the statutory severance indemnity (L.1234-9)
The statutory severance indemnity is calculated according to the following formula:
- 1/4 of a month’s salary per year of service for the first 10 years.
- 1/3 of a month’s salary per year of service beyond 10 years.
The reference salary is the more favourable of: the average of the last 12 months, or one-third of the last 3 months (including bonuses and gratuities pro-rated).
Step 2: Double the statutory indemnity
Special indemnity = 2 × statutory indemnity.
This is the core of Article L.1226-14. Caution: only the statutory indemnity is doubled. The indemnity provided for by the collective bargaining agreement is never doubled, unless the collective agreement expressly provides for it (Cass. soc., 25 March 2009, No. 07-41.708, Bull. V No. 83; 18 February 2015, No. 13-20.171; 20 November 2024, No. 23-14.949).
Step 3: Compare with the collective-agreement indemnity
You must perform a mandatory comparison:
- A = 2 × statutory indemnity (special indemnity, L.1226-14).
- B = collective-agreement severance indemnity (not doubled, calculated according to the scale of your collective bargaining agreement).
You pay the more favourable amount to the employee: max(A, B).
There is neither combination nor addition of the two: it is one or the other (Cass. soc., 10 May 2005, No. 03-44.313, Bull. V No. 153; 23 January 2013, No. 11-25.851).
Concrete Calculation Example
Situation: an employee with 15 years of service and a reference salary of €3,000 gross.
Calculation A — Special indemnity (double the statutory):
- Statutory indemnity = (1/4 × 3,000 × 10) + (1/3 × 3,000 × 5) = 7,500 + 5,000 = €12,500
- Special indemnity = 2 × 12,500 = €25,000 gross
Calculation B — Collective-agreement indemnity (example CBA):
- Suppose the agreement provides 1/3 of a month per year of service = 1/3 × 3,000 × 15 = €15,000
Comparison: A (€25,000) > B (€15,000) → pay €25,000 gross (special indemnity).
Had the agreement provided an indemnity of €30,000: B (€30,000) > A (€25,000) → pay €30,000 (collective-agreement indemnity, not doubled).
How to Calculate the “Amount Equal to Notice” Indemnity?
This is the second amount provided for by L.1226-14. Its amount is equal to that of the compensatory indemnity in lieu of notice (Article L.1234-5), but its legal nature is different. It is not an indemnity in lieu of notice — it is a specific termination indemnity.
Calculation Rules
- The quantum is determined by reference to the statutory notice period, not the contractual notice period even if the latter is longer (Cass. soc., 12 July 1999, No. 97-43.641; 20 November 2024, No. 23-14.949).
- The doubling of the notice period for disabled workers does not apply to this indemnity (Cass. soc., 10 March 2009, No. 08-42.249; 4 September 2019, No. 18-13.779).
Social Security and Tax Treatment
- Subject to social security contributions (Cass. soc., 11 January 2017, No. 15-19.959).
- Does not give rise to paid leave entitlement (Cass. soc., 4 December 2001, No. 99-44.677; 30 April 2014, No. 12-28.374; 7 February 2024, No. 22-15.988).
- Excluded from the base for the compensatory indemnity for paid leave (Cass. soc., 12 October 2011, No. 10-18.904).
- Does not postpone the contract end date: the contract ends on the date the dismissal is notified (Cass. soc., 15 June 1999, No. 97-15.328).
- May be combined with daily social security benefits (IJSS).
Example
A managerial employee (cadre) with a 2-month statutory notice period and a salary of €3,000 gross → indemnity = €6,000 gross.
What Wording Should Be Used on the Payslip?
Terminological rigour is essential to avoid any subsequent dispute:
On the payslip
- For the special indemnity: “Special severance indemnity – Art. L.1226-14 (double the statutory – Art. L.1234-9)” OR “Collective-agreement severance indemnity (not doubled) – more favourable”.
- For the indemnity equal to notice: “Termination indemnity – Art. L.1226-14 – amount equal to the compensatory indemnity in lieu of notice (Art. L.1234-5)”.
Absolutely to be avoided: any isolated occurrence of “compensatory indemnity in lieu of notice” as a heading. This terminological confusion can generate ancillary claims (claims for paid leave on the notice period, postponement of the contract end date, etc.).
In the dismissal letter
Explicitly cite Articles L.1226-12 (2nd paragraph) and L.1226-14 as the basis for the indemnities paid, distinguishing the two amounts.
What Are the Most Common Errors to Avoid?
- Doubling the collective-agreement indemnity instead of the statutory one — a costly and legally unfounded error.
- Adding the special indemnity and the collective-agreement indemnity — it is one or the other (whichever is more favourable).
- Omitting the A vs B comparison — mandatory in all cases.
- Confusing the “amount equal to notice” indemnity with a genuine indemnity in lieu of notice.
- Calculating in net instead of gross — the special indemnity is expressed in gross (Cass. soc., 7 May 2024, No. 22-21.479).
- Using the contractual notice period for the L.1226-14 indemnity — only the statutory period counts.
What If Length of Service Is Insufficient for the Statutory Indemnity?
If the employee does not have the length of service required for the statutory indemnity, the calculation gives: A = 2 × 0 = 0. In that case, B (the collective-agreement indemnity) is calculated; if B > 0, B is paid. The special indemnity may therefore be nil if the collective-agreement indemnity is also nil — but this is a rare case, since most collective bargaining agreements provide for lower length-of-service conditions.
Special Case: Fixed-Term Contract Terminated for Work-Related Unfitness
For a fixed-term contract (CDD — contrat à durée déterminée), the termination indemnity may not be less than double the statutory severance indemnity (Article L.1226-20, paragraph 4), with no requirement of one year’s service (pro-rated if less than one year). Added to this is the precariousness bonus (10%) which is cumulative — early termination for unfitness not being one of the exclusion cases under Article L.1243-10.
Calculation Checklist — Summary in 6 Steps
- Fix the dates: the unfitness medical examination, receipt of the medical opinion, notification of dismissal.
- Qualify the origin as of the termination date: work-related (workplace accident / occupational illness) or not.
- Calculate A = 2 × statutory indemnity (L.1234-9).
- Calculate B = collective-agreement indemnity (not doubled).
- Pay max(A, B) + the L.1226-14 “amount equal to notice” indemnity (statutory duration).
- Correctly label the payslip and the letter (references to the articles, exact terminology).
FAQ — Special Indemnity for Work-Related Unfitness
Is the special indemnity subject to income tax?
The special severance indemnity follows the tax treatment of severance indemnities: it is exempt within the limits provided by Article 80 duodecies of the French General Tax Code (CGI) (the higher of twice the gross annual remuneration or 50% of the indemnity paid, up to a ceiling of 6 times the annual social security ceiling / PASS).
Can the special indemnity be combined with damages?
Yes. If the dismissal is found to be without real and serious cause (for example, for failure to redeploy the employee), the employee may obtain damages in addition to the special indemnity. The minimum compensation floor is 6 months’ salary (Article L.1226-15), without application of the “Macron scale” (barème Macron — the statutory scale capping unfair-dismissal damages).
Can the collective-agreement indemnity be doubled?
No, unless the collective bargaining agreement expressly provides for it. In the absence of a doubling clause, only the statutory indemnity is doubled. The collective-agreement indemnity serves solely for comparison purposes (Cass. soc., 25 March 2009, No. 07-41.708).

The Procedure for Recognising a Workplace Accident or Occupational Illness
Managing workplace accidents and occupational illnesses (AT/MP) is a major issue for the employer, both on a human and a financial level. The legal framework is set out in Articles L.411-1 et seq. of the French Social Security Code.
Regarding workplace accidents, Article L.411-1 of the Social Security Code defines a workplace accident as any accident arising as a result of or in connection with work, whatever its cause. The presumption of imputability benefits the employee: as soon as the accident occurs at the time and place of work, it is presumed to be work-related.
The employer must:
- Declare the accident within 48 hours (Article R.441-3 of the Social Security Code) via the DSN (unified social declaration) or Cerfa form No. 14463*03
- Provide the employee with the accident sheet (form S6201) enabling them to benefit from 100% coverage of medical expenses
- Issue reasoned reservations where applicable, within the accident declaration (DAT) itself, if the employer has doubts as to the work-related nature
The CPAM (local health insurance fund) has 30 clear days to rule on recognition of the work-related nature (90 days in the event of further investigations). See our AT/MP guide to understand your rights and obligations.
The Financial Impact of Workplace Accidents / Occupational Illnesses on Employer Contributions
The AT/MP contribution rate is directly linked to the company’s claims experience. Three pricing methods exist depending on headcount:
- Collective pricing (companies with fewer than 20 employees): rate set by business sector
- Mixed pricing (20 to 149 employees): a combination of the collective rate and the company’s own rate
- Individual pricing (150 employees and above): rate calculated on the establishment’s own claims experience
The average cost of a workplace accident is categorised according to the duration of the work stoppage and the after-effects. A serious accident with permanent incapacity can affect the AT/MP rate for 3 consecutive years, representing a considerable additional contribution cost.
The Court of Cassation held, in a ruling Cass. 2e civ., 11 January 2024, No. 22-11.789, that the employer may challenge the enforceability of the coverage decision even after the deadline for challenging the contribution rate, provided it invokes a substantial procedural defect.
It is therefore essential to establish active monitoring of your AT/MP rates and to challenge coverage decisions when the conditions of the presumption of imputability are not met. Our firm, via DAIRIA IA, can support you with automated tracking of your claims experience.
