If you become a self-employed person, you are, in principle, obliged to join a social insurance fund. One of these social insurance funds is the social insurance fund of the NISSE: the National Fund. 

Predefined term for joining
You have to join a social security fund not later than the first day of your self-employed activity. We advise you to join a social security fund in time.
If you join late:

• you will risk an administrative fine ranging from € 500 to € 2,000;
• you will receive a reminder which gives you 30 days to join a social security fund.

If you do not comply, you will automatically become a member of the National Fund.


Social contributions
Every three months you must pay social contributions to your social insurance fund. 
This will entitle you to:

• family benefit
• pension
• health insurance (for large risks and inability to work)
• continued insurance
• bankruptcy insurance
