The buyout of work accident annuities has long allowed victims to convert a portion of their lifetime annuity into immediate capital. The Social Security Financing Law for 2020 removed this possibility of partial buyout. The AT-MP reform resulting from the law of February 28, 2025, broadly reshapes the compensation framework. Preparing a file in 2026 requires understanding which regime applies based on the date of the incident, what documents to gather, and which deadlines to respect.
Applicable regime based on the date of the incident: comparative table
The most common confusion concerns the temporal application of the reform. An accident that occurred before the entry into force of the removal of the partial buyout is not subject to the same rules as a more recent incident. The table below summarizes the distinctions to know before any steps are taken.

| Criterion | Incident prior to 2020 | Incident after 2020 |
|---|---|---|
| Partial buyout (conversion to capital) | Possibility open if rights already validated | Removed by the LFSS 2020 |
| Structure of the annuity | Annuity calculated on the overall permanent disability rate | Distinction between functional part / professional part (2025 reform) |
| Key supporting documents | Medical certificate, IPP notification, career statement | Proof of income loss, evidence of professional impact |
| Processing time (general regime) | Variable, often several months | Schedule aligned with the AT-MP reform 2025 |
| Agricultural regime (MSA) | Specific processing window | Shifted compared to the general regime |
The distinction between already opened rights and new files conditions the entire strategy. An employee whose partial buyout was validated before the removal retains their acquired rights. In contrast, a file opened after 2020 can no longer claim this conversion to capital.
Understanding the steps for the buyout of work accident annuity 2026 first involves verifying the date of the incident and the status of the file with the CPAM.

Functional part and professional part: the new logic of proof
The AT-MP reform enacted on February 28, 2025, introduces a dual compensation that separates physical harm from economic harm. This distinction profoundly changes the way to prepare a file.
The functional part covers the physical or psychological deficit related to the accident. The professional part, on the other hand, aims at the actual loss of income and the consequences on the employee’s career.
Documents to gather to demonstrate income loss
Competing articles mention this duality without detailing the expected supporting documents. For an employee in intermittent or precarious employment, the proof of the actual professional impact is the main sticking point. Here are the documents to collect:
- The pay slips from the twelve months preceding the accident and those following the resumption, to objectify the income gap
- Certificates from successive employers or Pôle emploi statements if the activity is fragmented, to document periods of unemployment related to the disability
- A detailed medical certificate establishing the link between the sequelae and the reduction of work capacity, distinct from the simple rate of permanent disability
- Any rejection letters for hiring or job adjustments that illustrate the concrete impact on employability
A solid file relies on the convergence between medical data and professional data. A high IPP rate alone is no longer sufficient to obtain optimal compensation: it is the quantified demonstration of income loss that makes the difference in the professional part.
Timeline of steps and discrepancy between general regime and MSA
The timing of the request varies depending on the organization to which the insured belongs. For the general regime, the CPAM processes annuity files according to a schedule aligned with the 2025 reform. Notifications of permanent disability rates and revisions follow a circuit that can take several months.
For insured individuals under the agricultural regime (MSA), the transition to the new rules does not occur at the same time as for the general regime. This discrepancy creates a window during which the steps must be anticipated separately.
Concrete steps before submitting a request
Before any submission to the CPAM or MSA, three verifications are necessary. First, check the notification of permanent disability: the established IPP rate conditions the type of annuity (quarterly payment for a rate between 10% and 49%, monthly beyond 50%). Next, verify that the consolidation medical certificate is up to date, as any dispute over the rate suspends the calculation of the annuity.
Finally, for employees whose accident occurred before 2020 and who still have rights to partial buyout, the request must be formalized quickly with the competent fund. No extension of the deadline has been announced for these residual situations.
Recourse in case of undervalued disability rate
A disputed IPP rate leads to a blockage of the entire annuity file. The dispute procedure goes through the amicable appeal medical commission and then possibly the judicial court (social division).
The point not to be overlooked: the 2025 reform uses the Mornet reference framework as the basis for calculating damages. This scale, derived from judicial practice in personal injury, modifies the reference amounts compared to the old system. Having an independent medical advisor evaluate your file before contesting allows for estimating whether the discrepancy justifies the procedure.
For victims of an employer’s serious fault, the reform now more strictly regulates the supplementary compensation related to permanent functional deficit. This change modifies the overall calculation and may reduce the interest of a recourse if the IPP rate is low.
Preparing a buyout or compensation file for AT annuity in 2026 hinges on documentary rigor and adherence to the specific timeline of each regime. An employee who gathers their income loss supporting documents, checks the date of their incident, and identifies their competent fund before submitting their request significantly reduces the risk of refusal or delay.
