The NSN replaces a very large number of returns. It allows you to pay your social contributions and communicate to social organizations (Urssaf, MSA: titleContent, France Travail, CPAM: titleContent...) the information necessary for the social protection of your employees. It's done online at net-companies.fr.

As a reminder, the date of submission of the NSN varies according to your workforce:

• if you use less than 50 employees : DSN must be performed no later than the 15th of the month following the period of paid work;
• if you use 50 or more employees : DSN must be performed no later than the 5th of the month which follows the period of paid work.
