How to Calculate the Special Termination Indemnity for Work-Related Inaptitude

When an employee is terminated due to work-related inaptitude (work accident or occupational illness), they benefit from enhanced compensation as provided by Article L. 1226-14 of the French Labour Code. However, calculation errors are common: mistakenly doubling the wrong indemnity, forgetting to compare with the collective agreement, confusing the amounts owed, etc. Here is the complete method to calculate correctly.

Table of Termination Indemnities for Inaptitude

The amount depends on the origin of the inaptitude. Here is an overview before diving into details:

Element	Non-Work-Related Inaptitude	Work-Related Inaptitude (AT/MP)
Termination Indemnity	Legal indemnity (art. L. 1234-9), or more favorable collective indemnity	Special indemnity = double the legal indemnity (art. L. 1226-14); the collective indemnity is not doubled
Notice	Not executed; no compensatory indemnity for notice, but notice is counted for termination indemnity calculation (art. L. 1226-4)	Indemnity equal to the compensatory indemnity for notice (art. L. 1226-14, referring to L. 1234-5), due even if the notice is not executed
Legal Basis	art. L. 1226-4	art. L. 1226-14

The rest of this article details the calculation of work-related inaptitude — the case most prone to errors.

What Does Article L. 1226-14 of the French Labour Code Provide?

Article L. 1226-14 provides that an employee terminated for work-related inaptitude is entitled to two distinct indemnities:

1. A termination indemnity equal to the compensatory indemnity for notice (article L. 1234-5).
2. A special termination indemnity equal to double the legal termination indemnity (article L. 1234-9), unless more favorable contractual provisions apply.

Here is the exact text: “The termination of the employment contract in the cases provided for in the second paragraph of Article L. 1226-12 gives rise to a compensatory indemnity equal to that of the compensatory indemnity for notice provided in Article L. 1234-5, as well as to a special termination indemnity which, unless more favorable contractual provisions apply, is equal to double the indemnity provided for in Article L. 1234-9.”

It is imperative to clearly distinguish between these two sums: they have different legal natures, calculation bases, and social/fiscal regimes.

How to Calculate the Special Termination Indemnity?

Step 1: Calculate the Legal Termination Indemnity (L. 1234-9)

The legal termination indemnity is calculated according to the following formula:

• 1/4 of a month’s salary per year of seniority for the first 10 years.
• 1/3 of a month’s salary per year of seniority beyond 10 years.

The reference salary is the more favorable of: the average of the last 12 months or one third of the last 3 months (including bonuses and prorated gratuities).

Step 2: Double the Legal Indemnity

Special indemnity = 2 × legal indemnity.
This is the core of Article L. 1226-14. Note: only the legal indemnity is doubled. The indemnity provided by the collective agreement is never doubled, unless expressly stated in the collective agreement (Cass. soc., March 25, 2009, n° 07-41.708, Bull. V n° 83; February 18, 2015, n° 13-20.171; November 20, 2024, n° 23-14.949).

Step 3: Compare with the Collective Indemnity

You must perform a mandatory comparison:

• A = 2 × legal indemnity (special indemnity L. 1226-14).
• B = collective termination indemnity (not doubled, calculated according to your collective agreement’s scale).

You pay the most favorable amount to the employee: max(A, B).
There is neither accumulation nor addition of the two: it’s one or the other (Cass. soc., May 10, 2005, n° 03-44.313, Bull. V n° 153; January 23, 2013, n° 11-25.851).

Concrete Calculation Example

Situation: Employee with 15 years of seniority, reference salary of €3,000 gross.

Calculation A — Special Indemnity (double the legal):

• Legal 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 Indemnity (example CCN):

• Assume the convention provides 1/3 of a month per year of seniority = 1/3 × 3,000 × 15 = €15,000

Comparison: A (€25,000) > B (€15,000) → payment of €25,000 gross (special indemnity).
If the convention provided an indemnity of €30,000: B (€30,000) > A (€25,000) → payment of €30,000 (non-doubled collective indemnity).

How to Calculate the “Indemnity Equal to the Notice”?

This is the second sum provided by L. 1226-14. Its amount is equal to that of the compensatory indemnity for notice (article L. 1234-5), but its legal nature is different. It is not a notice indemnity — it is a specific termination indemnity.

Calculation Rules

• The amount is determined by reference to the legal notice period, not the conventional duration even if it is longer (Cass. soc., July 12, 1999, n° 97-43.641; November 20, 2024, n° 23-14.949).
• The doubling of the notice period for disabled workers does not apply to this indemnity (Cass. soc., March 10, 2009, n° 08-42.249; September 4, 2019, n° 18-13.779).

Social and Fiscal Regime

• Subject to social contributions (Cass. soc., January 11, 2017, n° 15-19.959).
• Does not entitle to paid leave (Cass. soc., December 4, 2001, n° 99-44.677; April 30, 2014, n° 12-28.374; February 7, 2024, n° 22-15.988).
• Excluded from the basis of the compensatory leave indemnity (Cass. soc., October 12, 2011, n° 10-18.904).
• Does not postpone the contract end date: the contract ends on the date of termination notification (Cass. soc., June 15, 1999, n° 97-15.328).
• Cumulates with IJSS (sickness benefits).

Example

Salary with a 2-month legal notice, salary of €3,000 gross → indemnity = €6,000 gross.

What Terminology to Use in Payroll?

Terminological rigor is essential to avoid any subsequent disputes:

On the payslip

• For the special indemnity: “Special termination indemnity – art. L. 1226-14 (double the legal – art. L. 1234-9)” OR “Collective termination indemnity (not doubled) – more favorable”.
• For the indemnity equivalent to the notice: “Termination indemnity – art. L. 1226-14 – amount equal to the compensatory indemnity for notice (art. L. 1234-5)”.

Absolutely to avoid: any isolated occurrence of “compensatory indemnity for notice” as a title. This terminological confusion can generate accessory claims (claim for paid leave on the notice, postponement of contract end date, etc.).

In the termination letter

Explicitly mention Articles L. 1226-12 (2nd paragraph) and L. 1226-14 as the foundations for the indemnities paid, distinguishing the two amounts.

What Are the Most Common Errors to Avoid?

1. Doubling the collective indemnity instead of the legal — a costly and unfounded legal error.
2. Adding the special indemnity and the collective indemnity — it is one or the other (the more favorable).
3. Omitting the comparison A vs B — mandatory in all cases.
4. Confusing the indemnity “amount equal to the notice” with a real notice indemnity.
5. Calculating net instead of gross — the special indemnity is calculated in gross (Cass. soc., May 7, 2024, n° 22-21.479).
6. Using the conventional notice duration for indemnity L. 1226-14 — only the legal duration counts.

What If the Seniority Is Insufficient for the Legal Indemnity?

If the employee does not have the required seniority for the legal indemnity, the calculation gives: A = 2 × 0 = 0. You then calculate B (collective indemnity); if B > 0, you pay B. The special indemnity can therefore be zero if the collective indemnity is also — but this is a rare case since most collective agreements provide for lower seniority conditions.

Special Case: Fixed-Term Contract Terminated Due to Work-Related Inaptitude

For fixed-term contracts, the termination indemnity cannot be less than the double of the legal termination indemnity (article L. 1226-20, paragraph 4), without a one-year seniority condition (prorated if less than one year). The precarity indemnity (10%) is also added — as early termination for inaptitude is not excluded by article L. 1243-10.

Calculation Checklist — Summary in 6 Steps

1. Freeze the dates: date of inaptitude examination, receipt of notice, notification of termination.
2. Qualify the origin at the termination date: work-related (AT/MP) or non-work-related.
3. Calculate A = 2 × legal indemnity (L. 1234-9).
4. Calculate B = collective indemnity (not doubled).
5. Pay max(A, B) + indemnity L. 1226-14 “amount equal to the notice” (legal duration).
6. Correctly label the payslip and letter (references to articles, exact terminology).

FAQ — Special Indemnity for Work-Related Inaptitude

Is the special indemnity subject to income tax?

The special termination indemnity follows the tax regime of termination indemnities: it is exempt within the limits set out by article 80 duodecies of the CGI (the higher of twice the annual gross salary or 50% of the indemnity paid, within the limit of 6 PASS).

Can the special indemnity be accumulated with damages?

Yes. If the termination is deemed to lack real and serious cause (e.g., failure to redeploy), the employee can obtain damages in addition to the special indemnity. The minimum compensation is 6 months’ salary (article L. 1226-15), without applying the Macron scale.

Can the collective indemnity be doubled?

No, unless expressly stated in the collective agreement. In the absence of a doubling clause, only the legal indemnity is doubled. The collective indemnity is used only for comparison (Cass. soc., March 25, 2009, n° 07-41.708).

The Procedure for Recognizing a Work Accident or Occupational Illness

Managing work accidents and occupational illnesses (AT/MP) is a major issue for employers, both from a human and financial perspective. The legal framework is defined by Articles L.411-1 and following of the Social Security Code.

With regard to work accidents, Article L.411-1 of the CSS defines the work accident as any accident occurring during the work, irrespective of its cause. The presumption of liability benefits the employee: once the accident occurs at the time and place of work, it is presumed professional.

The employer must:

• Report the accident within 48 hours (article R.441-3 of the CSS) via DSN or Cerfa form n° 14463*03.
• Provide the employee with the accident form (form S6201) allowing them to receive 100% coverage of medical expenses.
• Make any motivated reservations if necessary, directly in the DAT, if the employer doubts the professional nature of the accident.

The CPAM has a period of 30 clear days to decide on the recognition of the professional nature (90 days in case of further investigations). Consult our AT/MP guide to learn about your rights and obligations.

The Financial Impact of AT/MP on Employer Contributions

The AT/MP contribution rate is directly linked to the company’s accident rate. There are three pricing methods according to the number of employees:

• Collective pricing (companies with fewer than 20 employees): rate set by sector
• Mixed pricing (20 to 149 employees): a combination of collective rate and own rate
• Individual pricing (150 employees and above): rate calculated based on the establishment’s accident rate

The average cost of a work accident is categorized based on the duration of absence and any sequelae. A serious accident with permanent incapacity can impact the AT/MP rate for 3 consecutive years, representing a considerable additional cost of contributions.

The Cour de cassation ruled in a judgment Cass. 2e civ., November 16, 2023, n° 22-11.789 that the employer can contest the enforceability of the coverage decision even after the contestation period for the contribution rate, as long as it invokes a substantial procedural flaw.

It is therefore essential to actively monitor your AT/MP rates and contest coverage decisions when the conditions of the presumption of liability are not met. Our firm, through DAIRIA IA, can assist you in the automated monitoring of your accident rate.
