Self-employed and subcontracting: 2026 rules

Updated March 2026 - The combination self-entrepreneur and subcontracting concerns thousands of freelancers, craftsmen and consultants in France. This model offers interesting flexibility to get started without administrative burden. But it exposes you to traps that many discover too late: illegal work, economic dependence and requalification into an employment contract. This guide details each mechanism for working safely.

Quick answer: a self-employed person can act as a subcontractor for a principal. The relationship must be framed by a written contract specifying the mission, price and deadlines. Of the 5,000 euros excluding tax, the ordering party must require a vigilance certificate. The main risk remains reclassification as an employee if a relationship of subordination is established.

Subcontracting consists, according to Entreprendre.Service-Public, for a principal to entrust to another company part of the production or service acts for which he remains responsible.

In the context of micro enterprise subcontracting 2026, the self-employed person acts as a second-tier service provider on behalf of a company which itself serves an end customer. The status of micro-entrepreneur imposes no restrictions on the use of subcontracting.

A self-employed person can therefore:

• act for a main client as a subcontractor;
• carry out a contractually defined service;
• bill your mission independently;
• itself subcontract part of its mission in certain cases.

The subcontracting contract: essential basis

The contract must imperatively specify:

• the exact nature of the mission and the scope of intervention;
• the price or the methods of calculating the remuneration;
• completion times and delivery stages;
• the obligations of each party;
• liability clauses and termination conditions.

A verbal contract exists legally, but it is almost impossible to prove in the event of a dispute. Writing is essential, even for short missions.

The vigilance certificate: the threshold of 5,000 euros excluding tax

As soon as a contract reaches 5,000 euros excluding tax, the principal must request a vigilance certificate from the subcontractor. This document, issued by URSSAF, certifies that the service provider is up to date with its social and tax obligations.

The principal must:

• obtain the certificate before the start of the mission or within 15 days;
• renew it every 6 months until the end of the contract;
• keep a copy for 5 years after the end of the contract.

In the event of default, the principal is liable to a fine of 1,500 euros (3,000 euros in the event of a repeat offense) and may be held jointly and severally responsible for the social security contributions and taxes of his subcontractor.

Obligation of means vs obligation of result

The danger does not come from subcontracting itself, but from the link of subordination. Service-Public points out that if this link is established, the judge can reclassify the relationship as an employment contract.

What is the relationship of subordination?

Legally, it is characterized by the execution of work under the authority of an employer who has the power to give orders, control their execution and sanction breaches. For a self-employed entrepreneur under contract, the boundary can be fine: the principal has a right to review the result, but must not control the execution methods.

Warning signs

• required hours: compulsory presence at fixed times;
• permanent instructions: directives comparable to those of an employee;
• absence of autonomy: no freedom in the organization of work;
• sustainable quasi-exclusivity: a single customer over a long period;
• organizational integration: badge, company email, internal meetings;
• materials provided: the principal provides all the tools;
• disciplinary power: sanctions in the event of delays or errors.

Hayot Expertise Advice: a self-employed person who always invoices the same client is not automatically at risk. The real subject is the proof of its autonomy: free organization, own pricing, several possible clients, absence of disciplinary power of the client. Maintain tangible elements of this independence (quotes to other prospects, professional site, invoices to several clients).

For the self-employed subcontractor

• keep all documents: quotes, contracts, purchase orders, written exchanges;
• issue compliant invoices with mandatory information and sequential number;
• follow its turnover thresholds: 77,700 euros for services in 2026;
• monitor your VAT situation: basic franchise up to 36,800 euros;
• diversify your clientele and prospect regularly;
• bill at your own rate, never on an hourly basis based on a salary.

For the ordering party

• check the vigilance certificate of 5,000 euros excluding tax;
• frame a results mission and not a relationship of subordination;
• avoid treating the self-employed as an employee: no badge, no imposed hours;
• keep the supporting documents for 5 years.

Working as a subcontractor does not modify the status ceilings. In 2026:

The turnover of subcontracting is added to your other income. Exceeding this leads to exit from the micro-enterprise regime.
