Annual declaration of social data 

DADS

The annual declaration of social data (DADS) is a declaration procedure which must be completed by all businesses that employ staff.

In this document, which serves both fiscal and social administrative purposes, employers provide certain information pertaining to their establishments and employees, annually and for every establishment.

For each employee the following information should be declared: the nature of the work and qualification, the starting and closing dates of the period of paid work, the number of paid hours, the terms of employment (full time, part time), the amount paid, etc.

For INSEE, details from DADS

Since 1947, all employers have been required to fill in an administrative document detailing the periods of employment and wages of their employees.

This compulsory formality must be completed by all businesses with employees, in line with article R243-14 of the Social Security Code (Decree of March 24th 1972) and articles 87.240 and 241 of Law 51-711 of June 7th 1951 of the General Tax Code.

Since 1950 INSEE has been the official recipient of this form, and responsible for its statistical use. Initially, INSEE used tax documents on loan from the general tax inspectorate.

In 1970, these documents became the "annual wage declarations" (DAS). INSEE thereafter began to receive its own copy of the declaration.

In 1984 the DAS, combined with the attestation of paid activity (AAS), became the "declaration of social data" (DADS). Until 1991, INSEE used the information relating to employees (1 in 25 full time employees born in October in even years).

In 1992 a method for transmitting data using magnetic tape was gradually phased in ("social data transfer" or TDS).

In 1998, the National Commission for Computer Technology and Liberties (CNIL) granted INSEE authorisation to comprehensively use the DADS data and publish the results.

From 2005 the TDS standard was replaced by a new computerised format, the "unified annual declaration of social data", allowing businesses and regional authorities operating a wage software program capable of integrating this new norm to provide a single digital declaration.
