What if my employee changes their address?

When an employee changes their address, no action is required through Salary.lu. However, the process differs depending on whether the employee is a Luxembourg resident or a cross-border worker (non-resident).

For Luxembourg residents

Employee responsibilities

Luxembourg residents who change their address must:

1. Go to their communal administration population office
2. Declare their address change following the commune's procedures
3. Ensure the declaration is completed promptly after moving

Automatic process

Once the resident employee has declared their address change:

1. The communal administration processes the address change
2. The address change is automatically communicated to the CCSS (Centre commun de la sécurité sociale)
3. Information is transmitted to relevant administrations including the ACD
4. The employee's tax card is automatically updated with the new address

For non-residents (cross-border workers)

Employee responsibilities

Non-resident employees who work in Luxembourg and change their private address can:

1. Make a request to update their data directly via MyGuichet.lu
2. Follow the online procedure for address updates
3. Ensure the update is completed promptly after moving

Employer actions (same for all employees)

As an employer, you need to:

1. Wait for the tax card to be updated by the ACD
2. Download the updated tax card once it becomes available
3. Add the new tax card to the employee's profile in Salary.lu

For self-employed persons

Self-employed persons who are changing their professional address must contact the CCSS via the contact page or via email.
