Depuis le 1er janvier 2026, the employer-specific contribution levied on the portion of a negotiated termination indemnity exempt from social security contributions has been increased to 40%. This change, effective immediately, materially alters the overall cost of a negotiated departure, the conditions governing negotiation, and the documentation requirements for securing compliance.
1 – What changes on 1 January 2026: a 10-percentage-point increase in the employer contribution
1.1 – An increase that immediately affects the employer’s total cost
Negotiated termination (rupture conventionnelle) remains a widely used mode of consensual separation, but it has never been cost-neutral for the employer. In 2026, the employer-specific contribution applicable to the exempt portion of the severance indemnity is raised to 40%, generating a mechanical cost increase across all files where the exempt portion is material.
1.2 – What exactly does this cover?
This is not an ordinary payroll contribution assessed on wages, but a dedicated levy, due at the time of termination, calculated on a precise basis: the portion of the indemnity benefiting from an exemption from social security contributions, within the limits and conditions set by applicable legislation.
Key point
The contribution does not systematically apply to the entire indemnity paid, but only to the portion exempt from social security contributions. An approximate reading — “40% of everything” — may lead to either overestimating or underestimating the actual employer cost depending on the circumstances.
2 – Scope: covered terminations and the contribution base
2.1 – Individual negotiated termination: the most common scenario
The rupture conventionnelle applies to open-ended employment contracts (CDI) and is formalised by an agreement signed between the employer and the employee, subject to approval (homologation) by the competent administrative authority. With approximately 500,000 approved negotiated terminations per year, this mechanism has established itself as the primary mode of consensual separation of CDI contracts in France. The indemnity paid in this context may, depending on the parameters specific to each case, benefit from partial exemptions, upon which the employer-specific contribution is calculated.
On the litigation front, the long-term trend has been favourable: the number of challenges has been halved over ten years, reflecting a gradual appropriation of the mechanism by both parties. However, this trend warrants monitoring, as the volume of disputes is slightly increasing, at around 100,000 cases per year. This context reinforces the importance of a rigorous approach, particularly in high-stakes matters.
2.2 – Calculation base: the exempt portion and its threshold effects
The amount of the contribution depends on how the indemnity is apportioned between the exempt portion and the portion subject to social security contributions, CSG/CRDS, and income tax. The portion exempt from social security contributions is capped at twice the annual social security ceiling (PASS), i.e. €96,120 in 2026. It is on this portion — and within this cap — that the 40% employer-specific contribution is assessed. A given gross indemnity may therefore result in materially different employer costs depending on the employee’s status, length of service, reference remuneration, and applicable ceilings.
2.3 – The termination timeline: a budgetary variable in its own right
In 2026, the date on which the termination takes effect — i.e. the contract end date — becomes a planning parameter that cannot be overlooked. A negotiation concluded at the end of 2025, but whose termination takes effect in 2026, is not governed by the same rules as a departure that occurred on 31 December 2025. The consistency of the timeline — signing, withdrawal period, submission, approval, termination date — must be verified and documented in advance.
3 – Why this increase materially changes the landscape for employers
3.1 – Mechanical cost increase: a file-by-file impact
In files where the indemnity includes an exempt portion, the rate increase produces an immediate effect on the all-in cost of separation. This is particularly significant in situations involving multiple departures, collective mobility agreements, restructurings, or workforce reductions outside the scope of a statutory redundancy plan (plan de sauvegarde de l’emploi).
3.2 – Impact on negotiation: budgets, trade-offs, and timing
The rate increase is liable to alter the balance of negotiations, particularly where the employer reasons in terms of an overall budget envelope. In practice, this tends to result in revising indemnity proposals at constant cost, making different trade-offs between amount, timing, and notice period arrangements, and imposing stricter traceability and internal approval requirements.
3.3 – Cumulative risk: increased cost and exposure to litigation
The cost increase must not prompt employers to accelerate the process at the expense of legal soundness. A challenged negotiated termination generates cumulative risk: management costs, managerial disruption, reputational harm to the employer brand, and, in the most serious cases, reclassification of the termination or an award of damages.
Caution
The more conflictual the context — pre-existing disputes, internal alerts, occupational health issues, allegations of coercion — the more a negotiated termination requires a documented strategy and rigorous drafting.
4 – Accurate costing in 2026: methodology and best practices
4.1 – Reasoning in terms of total employer cost
To avoid discrepancies between decisions and actual budgetary impact, the employer must consolidate a comprehensive view encompassing all components: indemnity, employer-specific contribution at 40%, charges and taxation applicable to each portion, and ancillary items (paid leave, variable elements, bonuses, benefits in kind). A rigorous simulation is also a negotiating tool: it enables the employer to hold to a budget without compromising the quality of the relationship.
4.2 – Verifying the employee’s retirement status
The applicable regime may vary depending on whether the employee is or is not in a position to draw a pension. This verification, which is often deferred, may alter the anticipated cost and the structure of the indemnity. It must be carried out before the agreement is finalised.
4.3 – Securing proof of consent and process integrity
The legal soundness of a negotiated termination rests on the overall coherence of the file: structured exchanges, an effective cooling-off period, absence of coercion, dated and versioned documents, and strict compliance with the statutory withdrawal and approval deadlines.
5 – What HR departments and senior management need to update
5.1 – Calculation tools and internal procedures
Costing templates, indemnity grids, and departure procedures designed under the former rate must be updated. A discrepancy between decisions taken and their actual cost is particularly problematic when multiple terminations are processed simultaneously.
5.2 – Approval workflows
In a context of increased cost, it is advisable to clearly formalise approval thresholds: indemnity amount, negotiation margin, sensitive clauses (confidentiality, non-disparagement), and internal communication arrangements. A structured and traceable decision-making process reduces the risk of error and subsequent litigation.
5.3 – Oversight of managerial communications
The line manager often plays a central role in the conduct of the negotiation. Poorly calibrated statements — whether amounting to pressure, threats, or insufficiently precise commitments — may undermine the employee’s free consent and expose the company to challenge. Training, supervising, and documenting exchanges is a precaution whose cost is limited relative to the risk incurred.
6 – Checklist: 8 questions to address before signing
- Has the cost been modelled as a total employer cost, including the contribution at 40%?
- Is the proposed termination date consistent with the administrative timeline (withdrawal period + approval)?
- Does the context present a risk of challenge (health, dispute, internal alert, discrimination)?
- Is the employee’s free consent objectively documentable (cooling-off period, exchanges, absence of coercion)?
- Has the employee’s retirement status been verified and factored into the analysis?
- Have ancillary items (paid leave, variable elements, bonuses) been correctly treated and substantiated?
- Are the ancillary clauses compliant and proportionate (confidentiality, non-disparagement, etc.)?
- Is the file in a condition to be produced in the event of an audit or challenge (versions, dates, submissions, evidence)?
