How do I set up the Mutuality Class and Bonus-Malus correctly?

This article explains how to configure mutuality class and bonus-malus factor settings for your company in Salary.lu, including default values for new companies and how to update them when you receive official documentation.

Default settings for new companies

If your company is in its first year, the system automatically applies these default values:

Mutuality class: Class 2
Bonus-malus factor: 1

These defaults remain active unless you receive specific instructions from the relevant authorities or update them manually.

Automatic updates for SECUline companies

As of 2025, companies using SECUline automatically receive the correct values from the CCSS. The system will apply these updates without manual intervention.

Manual updates when required

If you receive official documentation indicating changes to the mutuality class or bonus-malus factor, follow these steps:

Log in to your Salary.lu account
Navigate to the employee profile
Scroll down to find the mutuality class and bonus-malus factor input fields
Enter the updated values as provided by the relevant authority
Save the changes

Important: Only update these values when you have received official documentation from the authorities. Do not change them based on assumptions.

What happens if I don't update these settings?

For companies where values are not automatically received from the CCSS, the system will continue using the default settings:

Class 2 for mutuality class
Factor 1 for bonus-malus

These defaults will remain until you manually update them with official values.

Note: If the values are not correct, calculations on some documents like the accounting allocation and salary book will not be fully accurate and will need to be updated later on.

Where to find the necessary details

You can obtain the required mutuality class and bonus-malus information through:

Official letters from the CCSS (typically MDE + AAA documents)
Direct email request to the CCSS asking for this information

Note: Always verify that any documentation is current and official before making updates to these settings.
