Requesting the reimbursement of a credit balance

Any person (natural or legal) with a credit balance on their contributor's account with the Social Security Centre (Centre commun de la sécurité social - CCSS), may ask for it to be paid into their bank account.

Persons concerned

Any person (natural or legal) who has a credit balance on their contributor's account with the CCSS.

How to proceed

General information

Examples of reasons for a credit balance:

a recalculation of the social security contributions due following a change in salary/income;
cancellation or retroactive termination of an affiliation;
a substantial reimbursement by the Employers' Mutual Insurance Scheme (Mutualité des employeurs - MDE) in the event of illness or an accident (this only applies to the contributor's accounts of employers, self-employed workers and farmers);
an overpayment (e.g. in the event of an erroneous transfer).

The person concerned (natural or legal) who has a credit balance has the choice between:

asking for a reimbursement into their bank account;
asking for the credit balance to be transferred to another contributor's account also belonging to them;
using the credit balance to pay off amounts due in the future. In this case, there is no need to request a reimbursement.

Requesting the reimbursement of a credit balance

A natural person who wishes to have a credit balance reimbursed into their bank account must send the 'Reimbursement form for natural persons' to the CCSS. A legal person must use the 'Reimbursement form for legal persons'.

These forms must be sent to the CCSS accompanied by a bank account identification document (RIB) issued by the bank of the person concerned. A copy of the account holder's bank card (MAESTRO or V-PAY) or a copy of a bank statement would also be accepted.

Asking to transfer a credit balance to another identification number

A person who has several contributor's accounts (identification numbers with different extensions) may ask the CCSS, in writing, to transfer a credit balance to another of their identification numbers. The request can be made via the CCSS contact page or by post to this address: CCSS Service comptabilité L-2975 Luxembourg.

Example

A self-employed worker who has a credit balance on their personal account (-60 extension) who wishes to use this credit to pay off a balance due on the account of a company of which they are the sole proprietor (-99 extension) or the account of their private household (-70 extension) may request that the balance be transferred.

Carrying a credit balance forward

If no request for the reimbursement or transfer of a credit balance is sent to the CCSS, the balance will automatically be used to cover the amounts due on the next statements.
