DRS - online service
What is DRS?
DRS stands for Declaration of social risks (‘Déclaration de risque social’ in French). A social risk is an unexpected event that has an impact on the social situation of an employee. This event may be a dismissal, temporary unemployment, a long-term illness, a workplace accident…
Employers need to declare these kind of social risks for their employees to the social security institutions.
What is the purpose of the DRS?
Based on your declaration, the competent social security institutions can determine whether your employee is entitled to benefits. This may involve:
- a benefit related to the allocation insurance and maternity insurance,
- a benefit following an accident at work,
- an unemployment benefit, income guarantee benefit or activation benefit.
When do you need to submit a DRS?
It depends on the situation when you need to submit a DRS. Some declarations have to be submitted at the moment the social risk occurs. Others are made monthly, for as long as the socially insured person fulfils the conditions to receive benefits. In certain cases a declaration is needed once the social risk ceases to exist.
Consult the Administrative instructions on DRS on the Social security enterprise portal (in French) to find out how to proceed for each type of DRS.
A DRS can be filed by the employer or by an appointed mandatary.
Declaration using the online service
Use the online service DRS by clicking on the button Introduce / Modify / Finalise / Cancel a declaration (‘Introduire / Modifier / Finaliser / Annuler une déclaration’ in French) on the DRS page of the Social security Enterprise portal (in French).
Batch declaration
Most mandataries or employers having a large workforce work with a file transfer (FTP or SFTP). Look into the principles of this batch processing on the Social security enterprise portal (in French).
There are 3 types of DRS, all containing several scenarios:
- Workplace accidents: consult the different scenarios on Workplace accidents on the Social security enterprise portal (in French);
- Unemployment scenarios: consult the different scenarios on Unemployment on the Social security enterprise portal (in French);
- Allocation scenarios: consult the different scenarios on Allocations on the Social security enterprise portal (in French). In this respect, health insurance funds also send out requests, which employers respond to with an ASR. Applications to be processed are available in the secure online service DSR, and in a company’s secure online mailbox, the e-Box. Consult more information on e-Box on the Social security enterprise portal (in French).
It can be useful to make dummy DRS declarations without actually submitting them. Therefore click on the button Introduce a declaration (demo version) (‘Introduire une déclaration (demo version)’ in French) on the DRS demo page of the Social security enterprise portal (in French).
Anyone can use the demo versions without a specific access procedure.
