Declaration of additional birth leave: a new mandatory form for employers
Publié le 03 novembre 2026 - Entreprendre Service Public / (Prime Minister)
Since 1er in november 2026, employers must use a new online form to report additional birth leave. This system replaces the Excel file that has been in place on a transitional basis since the entry into force of the supplementary birth leave on 1er July 2026.
The new service available on ameli.fr since 1er november 2026 allows an employer to provide:
- information about the employee
- information about the child
- information about the employer (SIRET, contact and company name)
- dates of additional birth leave
When the document is completed, a PDF is generated automatically. The employer must file the document on its Company Account accessible via Net-companies, or transmit via the attachment deposition API.
Warning
The arrival of this new form does not change the existing reporting obligations. For each period of additional birth leave, the employer must always take two steps on the same day :
- transmit an alert by DSN: titleContent (or a statement of salary if the DSN report is not available);
- submit the application form on the company Account
