New features of the AT/MP account
Publié le 07 novembre 2025 - Entreprendre Public Service / Legal and Administrative Information Directorate (Prime Minister)
Net-company.fr offers 3 new services since October 23, 2025. They aim to simplify procedures and increase the transparency of the Workers' Compensation and Occupational Diseases (AT/PM) account. This platform enables employers to manage their entire business.

The 3 new online features of the AT/MP account
Online application for the “support functions” rate
Companies in mixed or collective pricing with less than 150 employees, may deorder directly online the rate “support functions”. This system simplifies the process since it was necessary to fill out a dedicated form before.
This makes it easier for the employer to manage contributions for administrative positions that are not exposed to a company's occupational risks.
AT/MP rate simulator
A simulator, accessible via the “Preventing occupational risks” section, now provides employers with the capacity accurately assess the impact of a loss reduction on the AT/MP contribution rate.
This service provides a better understanding and understanding of the link between the different AM/TP contribution rates.
Notification to third-party registrants
When the new AT/MP rates are made available, third-party registrants (payroll provider, accountant...) will receive a email notification.
They will be able to download them in PDF. They will have an identification of the tariff variations and an acknowledgement of receipt that groups all the rates.
This service is available under the heading “Consult rate decisions of clients in my portfolio”.
There is 2 conditions for access to decisions:
- authorization by their client to the “Consult your AT/MP rates” service;
- an NSN must have been performed within the last 3 months.
This allows full visibility for third-party reporting.
