ATMP rate: Compulsory dematerialization – Last straight line

From 1er January 2022, the dematerialization of ATMP rates becomes mandatory for all companies, including those with fewer than 10 employees.

Only a few weeks left to prepare for it and approach this administrative development calmly. Indeed, if you do not yet have a Net-Entreprises account, you have until 1er December 2021 to register.

Our consultants are able to assist you with the registration procedure.

For the time being, we suggest that you take a look at some essential concepts around the methods of calculating the ATMP rate.

How is the ATMP rate calculated?

A company's ATMP rate is determined based on two parameters:

  • The nature of its activity, classified according to “risk codes”
  • The size of the company, ie its overall workforce, all establishments combined (except those in Alsace-Moselle).

The determination of the workforce of a company with several establishments is established by the sum of the workforce of each establishment, including part-time employees


Collective pricing is applicable to two types of business

• Companies or establishments whose workforce is less than 20 employees ;

• Newly created companies or establishments during the first 3 years of existence.


Actual pricing is based on an assessment of the actual cost of risk in the institution concerned.

It is applicable to companies whose the usual workforce has at least 150 employees.


The mixed rate applies to companies whose the usual workforce is between 20 and 149 employees. This rate is obtained by adding a fraction of the collective rate of the branch of activity to which the company belongs, and a fraction of its actual net rate.

To note : The fraction of each of these rates varies according to the number of employees.

The ATMP rate also depends on the loss experience of your company

Our team of legal consultants assists you in managing your claims in order to optimize your ATMP rate.
