Unified Annual Social Data Declaration (UDAD)

Verified 02 July 2020 - Directorate for Legal and Administrative Information (Prime Minister)

The Nominal Social Declaration (DSN) replaces the Unified Annual Social Data Declaration (UDAD) in most companies. However, a number of employers must continue to complete the U-DADS.

Employers who are required to file a Unified Annual Social Data Return (UDAR) are:

  • Employers who complete the social declaration nominative (DSN) but employ populations outside DSN boundaries. Examples: fishermen, dockers, officials on secondment to a private establishment.
  • Public service employers
  • Institutions completing the NSD that could not transmit data from complementary bodies (CBs) in the DSN.

Warning  

all other employers must perform a registered social declaration (DSN)..

In the event of a delay, omission or inaccuracy of the reported data, the employer risks the payment of a penalty equal to €51 per employee up to €750 by declaration.

If the delay exceeds 1 month, an identical penalty shall be applied for each month or fraction of a month of delay.

The U-DADS must contain the following elements:

  • Identification of employer and employee 
  • Characteristics of employment and employment contract 
  • Period of employment 
  • Earnings received in the previous year 
  • Contributions (and contribution bases) used for entitlement to old-age and health insurance.

The U.S. DADS must list one of the following 3 reasons for filing:

  1. EX: DSN-filling employer with populations excluded from DSN perimeter
  2. NO: employer not subject to the obligation to fulfill the DSN
  3. OC: employer who did not transmit the data OC (complementary bodies) in DSN

A company that has payroll software that complies with 4DS (electronic data interchange) "EDI") must file the U-DADS online:
