Definition
Camille left her developer job in January 2026. Three weeks later her former employer called back: same desk, same badge, same Monday morning meeting, same manager approving her time off.
The one difference is that she now sends an invoice instead of receiving a payslip. On paper she is self-employed. In front of a judge, that relationship has another name.
Requalification en salariat (reclassification as employment) is the decision by which a judge sets aside the label the parties put on their contract and treats it for what it is: an employment contract.
The classification depends neither on what the parties intended nor on the title typed at the top of the document. It depends on the factual conditions in which the work is carried out.
A services contract stating in so many words that no subordination exists between the parties counts for nothing when the facts say otherwise.
Being a Micro-entrepreneur is in itself neither a shield nor a weakness: it is the wrapper the judge opens.
Subordination, the only test that decides
Registration works in your favour to begin with.
Article L8221-6 of the Code du travail (labour code) presumes that a person registered as self-employed, the one holding a SIRET number, is not bound to the client by an employment contract.
That presumption is rebuttable: it falls as soon as permanent legal subordination is established, and the same article provides that dissimulation d'emploi salarié (concealed employment) may then be held against the client.
Since a Cour de cassation ruling of 13 November 1996, subordination is recognised by three powers held by the client: giving orders and instructions, checking that they are carried out, and sanctioning failures.
The indicators judges look for are always the same: imposed working hours, equipment and software supplied by the client, integration into a team and into a service organised by someone else, prices set unilaterally, a duty to report, and no client base of your own.
The Cour de cassation followed that reasoning for a bicycle courier on 28 November 2018, then for a private hire driver on 4 March 2020: constant geolocation, imposed fares, and the power to deactivate the account.
Read backwards, that list becomes a way of working.
Il faut un devis décrivant un résultat, un délai et un prix plutôt qu'une présence hebdomadaire. Il faut vos propres outils et votre propre poste de travail.
Il faut la liberté d'organiser vos journées et de refuser une mission.
Il faut enfin une facturation au livrable plutôt qu'à la journée passée sur place, et la possibilité d'envoyer un remplaçant ou de sous-traiter.
None of these points is enough on its own, and none can be bought with a clause: they are proved by emails, quotations and deliverables. That is the material a judge examines.
What reclassification changes, and for whom
Camille invoices 3,000 € a month to that client, so 36,000 € collected in 2026.
As a developer in a non-regulated liberal activity, she falls under BNC (bénéfices non commerciaux, non-commercial profits) in the general scheme, and not under Cipav, which only covers regulated professions: her Social contributions are calculated at 25.6% in 2026, so 9,216 €.
That rate does not cover everything she owes URSSAF.
The CFP (vocational training contribution) comes on top, at 0.2% for liberal professions in 2026, but it is only due once turnover has been declared for the previous calendar year: Camille started in 2026, so she will pay it from 2027, meaning 72 € on the same turnover.
And none of that covers income tax: the 34% standard allowance in 2026 leaves 23,760 € to add to her household's taxable income.
Reclassification tips the whole arrangement over, and two courts deal with it without judging the same thing.
The conseil de prud'hommes (employment tribunal), if Camille brings the case, can reconstruct an employment contract, order back pay, holiday pay and overtime, and treat the end of the assignment as a dismissal without real and serious cause; invoices already paid are set off against the sums owed.
URSSAF, for its part, acts during an URSSAF audit at the client's premises: it recalculates contributions based on a salary, employer and employee shares alike, on a scale that has nothing to do with the micro-enterprise flat rate.
That is precisely why your clients ask for an URSSAF compliance certificate: that document covers them on the payment of your contributions, never on the nature of the relationship.
The single-client myth
No legal text sets a minimum number of clients, nor a share of turnover above which reclassification would automatically follow. The thresholds circulating on blogs and forums rest on no source at all: they are invented.
Working for one client is lawful, and it is the ordinary situation in many first years of trading.
Conversely, having ten clients protects you from nothing if subordination is established with one of them.
The number of clients is only one indicator among others, the one about having a client base of your own, and it carries weight only alongside the rest.
The same goes for premises: working at your client's office is not forbidden, and it becomes an indicator only once hours, a superior and sanctions are added to it.
Not to be confused with concealed employment or economic dependence
Three notions are constantly mixed up. Reclassification is a civil matter: it changes the nature of a contract and creates debts.
Travail dissimulé (concealed work) through concealed employment is criminal: it requires the client to have intentionally evaded its obligations, and the labour code attaches a fixed indemnity for the worker on top of everything else.
Economic dependence, finally, has nothing to do with employment law: a client who represents most of your activity and who walks away overnight incurs liability on commercial grounds, for abruptly ending an established business relationship, with employment status playing no part.
The most exposed case remains Camille's: invoicing the same tasks to your former or current employer.
Combining with employment is perfectly legal, subject to any Exclusivity clause, but invoicing your own employer for the work he was paying as salary yesterday is the arrangement URSSAF looks for first during an inspection.
Moving from employee to contractor means changing the assignment, the autonomy and the method, not merely the paperwork.
Frequently asked questions
Can I have only one client as a micro-entrepreneur?
Yes, no rule forbids it, and it is the situation of many people in their first year of trading.
What matters is how you work for that client: if you set your own hours, methods and prices, the number of clients puts you in no danger at all.
Who has an interest in claiming reclassification?
Almost always the worker, before the conseil de prud'hommes, because it opens the door to back pay and severance compensation.
URSSAF follows the same reasoning for a different purpose, collecting contributions, and there it is the client who pays.
Does a clause ruling out subordination protect the client?
No, and its presence rather suggests the question came up while the contract was being drafted.
The judge examines the real conditions in which the work was performed, not the statements of intent the parties signed together.
What does the micro-entrepreneur risk personally?
No penalty: reclassification is in principle in his favour.
He does lose the client overnight, however, and the amounts already collected on his invoices are deducted from whatever the judge awards him as salary.
