Amending your activity declaration (NDA): the procedure when something changes

A change of address, a new managing director, a new training specialty added to your catalogue: these everyday changes in the life of a training organisation all trigger the same obligation, one that is too often overlooked — filing an amended declaration for your activity declaration number (NDA). Unlike the initial declaration (Cerfa 10782), it gets no public fanfare. Here is what you need to know so it doesn’t catch you off guard.

A legal obligation, not an optional courtesy

Article L. 6351-4 of the French Labour Code requires you to notify the administration of any change to the elements that appeared in your initial activity declaration. The deadline is set by article R. 6351-8: 30 days from the date of the change. The recipient is the same authority as for the initial declaration — your regional DREETS — and since the process went fully digital, it is handled exclusively through the “Mon Activité Formation” (MAF) portal, at mesdemarches.emploi.gouv.fr.

This is not left to the director’s discretion. An activity declaration that no longer reflects your organisation’s actual situation directly weakens your NDA: during an inspection, any inconsistency between the official registers and your real situation is a red flag that triggers further checks, and can be treated as a breach of your reporting obligations.

Changes that trigger an amended declaration

Change of address

Whether it’s a relocation of your registered office or the opening of a new site where training takes place, the address on file must stay accurate. This is often the most common oversight among fast-growing organisations that change premises in their first few years.

Change of director or legal representative

A new managing director, a new SASU chairperson, a share transfer that changes the responsible individual: the director’s name is one of the constituent elements of the declaration. A change must be reported, particularly because the director’s criminal record extract (bulletin n° 3) was part of what conditioned the initial registration.

Change of company name

A rebrand, a merger, a change of trading name: if the legal name changes at the trade register, it must change in parallel on your activity declaration.

Change of legal structure

Moving from a sole proprietorship (micro-entreprise) to a SASU, converting an EURL into a SARL: the legal structure declared initially must be updated.

Broadening your training scope

You add a new specialty (NSF codes), or you start offering skills assessments (bilan de compétences) or VAE support when your initial declaration only covered standard training courses: these scope changes must also be reported, since they determine which types of funding you can access.

Ceasing activity

If you permanently stop your training activity, the cessation must also be declared within 30 days — this is what prevents a “ghost” NDA from staying active in the administration’s records.

What does NOT require an amended declaration

To avoid unnecessary paperwork, some changes fall outside the scope of the amended declaration:

• a change in revenue or number of trainees (this information belongs in the annual pedagogical and financial report (BPF), not the activity declaration);
• hiring or losing an employed trainer, unless it invalidates the list of instructors attached to the initial file for a filing still under review;
• a change of email address or phone number unrelated to the registered office address.

The step-by-step procedure on Mon Activité Formation

1. Log in to your account on mesdemarches.emploi.gouv.fr with the credentials used for your initial declaration.
2. Select the amended (rectificative) declaration procedure, linked to your existing NDA — you are not creating a new file from scratch.
3. Fill in the changed field(s): address, director, company name, legal structure or specialties, depending on the reason for the change.
4. Attach supporting documents for the change: an up-to-date Kbis extract for a change of address, director or company name; the new director’s criminal record extract (bulletin n° 3) where applicable; supporting proof of the new specialty (programme, agreement) for a scope extension.
5. Submit and keep the acknowledgement of receipt, which proves the filing date — your evidence that you met the 30-day deadline in case of an inspection.

The NDA itself does not change: the same 11-digit number stays attached to your organisation, only the information associated with it is updated.

Amended NDA and Qualiopi audits: a point of vigilance

During a surveillance or renewal audit, the auditor checks consistency across three sources: your activity declaration, your Kbis extract, and the information shown to the public (website, quotes, agreements). An outdated address or company name on your declaration, when it has already changed everywhere else, is an easily spotted gap — one that falls under the legal and regulatory monitoring expected by indicator 23 of the National Quality Framework and the accuracy of public information required by indicator 1.

The right habit: treat updating your activity declaration as a systematic step in any administrative change, on par with updating your Kbis, your articles of association or your bank details with funders. Add it to your Qualiopi audit preparation checklist so it never slips through the cracks before the auditor’s visit.

The consequences of forgetting

Missing an amended declaration does not automatically make your NDA lapse — that mechanism is reserved for failing to file the annual pedagogical and financial report or for having no training activity for two consecutive years. But the practical consequences are still real:

• documentation inconsistencies flagged during a DREETS inspection or a Qualiopi audit, which generate non-conformities;
• friction with funders (OPCO, Caisse des Dépôts for CPF), whose systems sometimes cross-check SIRENE data against Mon Activité Formation records;
• breach of a legal obligation, technically subject to sanctions even though inspections targeting this alone remain rare in practice.

Quick checklist

• Does the change concern the address, the director, the company name, the legal structure or the training scope?
• Is the amended declaration filed on Mon Activité Formation within 30 days?
• Are the supporting documents attached (up-to-date Kbis, bulletin n° 3 if needed)?
• Is the acknowledgement of receipt archived in your Qualiopi evidence file?
• Do your website, quotes and agreements show the same address and company name as your declaration?

Take action

Keeping your activity declaration up to date is one of those administrative habits that heads off audit gaps before they happen. The Complete Qualiopi Kit includes an administrative monitoring checklist and evidence tables for all 32 indicators, so you’re never caught off guard. Just starting your training organisation? The ebook Create Your Training Organisation in 30 Days walks through the initial declaration step by step — or go for the complete pack, which covers both creation and certification.
