Business Registration for Liberal Professions: The Rules to Know in 2026

Lawyer, doctor, accountant, consultant or trainer: in France, liberal professions now represent 1.7 million businesses and 3 million active workers, or 40.8% of the national productive fabric, according to the 2024 key figures published by UNAPL. Nearly 98.5% of these structures are very small businesses with fewer than 10 employees. In other words, the question of where to register a registered office concerns a huge share of self-employed professionals and small practices across the country.

But registering the address of a liberal activity does not follow exactly the same rules as a standard commercial company. Between the ethical requirements of professional bodies, the limits imposed on sole traders under the BNC tax regime, and the frequent confusion between an administrative address and an actual place of practice, this topic deserves careful treatment. Here is what you need to know before choosing a solution, wherever you practice in France.

Administrative registration versus place of practice: a distinction you cannot skip

The first mistake many liberal professionals make is confusing two separate concepts: the registered office address (which appears on the national business register and official documents) and the place where the activity is actually carried out. A business cannot exist without an officially declared address, whether through registration with the trade and companies register for a commercial activity or through the specific registration process for each regulated profession.

For some liberal professions, these two addresses can be entirely different. For others, they must coincide, or nearly so.

Regulated health professions

A doctor, nurse or physiotherapist who receives patients must have premises that comply with the standards set by the regional health agencies (ARS): an examination or treatment room, wheelchair accessibility, secure storage for medical equipment. A simple administrative registered-office address, without an associated practice location, is therefore not enough for this type of activity. Registration can cover the administrative head office of the structure (for instance a professional practice company), but the treatment room remains a separate space, subject to its own rules.

Intellectual and consulting professions

Conversely, a consultant, trainer, designer or psychologist working remotely or at clients' premises does not need dedicated premises to receive the public. For these activities, an approved business address provider can cover the entire need: a professional address, mail reception and scanning, sometimes a phone answering service.

Regulated professions: rules set by professional bodies

For professions subject to a professional body (lawyers, chartered accountants, notaries, architects, medical professions operating as a company), registering an address is not a mere administrative formality: it is governed by ethical rules specific to each profession.

The case of lawyers

Registering a law firm's address is governed by the National Bar Council and by the local Bar Council the lawyer belongs to. The address must be chosen within the jurisdiction of the lawyer's bar, and the choice must be approved by the Bar Council. The Paris Bar, like regional bars including the Marseille Bar, requires that the premises guarantee sufficient confidentiality for keeping case files and respecting professional secrecy. Registering at a personal home address is tolerated, but bar councils generally recommend not extending it beyond a few years without an alternative solution.

Other regulated professions

Chartered accountants, notaries and architects follow a similar logic: the registered address must allow practice under conditions consistent with the profession's standards, including a room ensuring the confidentiality of client files. In most cases, the relevant professional body must be informed of any change of professional address, in the same way a change is reported to the commercial court registry.

Before signing a registration agreement, a regulated professional should check with their professional body whether formal approval or a simple notification is required: practices vary by profession and by jurisdiction.

Sole traders under the BNC regime: a recent but regulated change

For a long time, self-employed workers carrying out a liberal activity as a sole trader under the BNC tax regime could not use standard commercial business-address services, unlike commercial companies. This restriction is gradually easing: some approved providers now offer a commercial registration service open to BNC activities, particularly for psychologists, trainers, designers and freelance consultants.

Two important points should be kept in mind, however:

• This registration remains commercial, not fiscal: it provides a professional address but does not change how the local business property tax (CFE) is calculated, which remains tied to the actual place where the activity is carried out.
• The offer is still limited in terms of cities and authorized providers: it is worth checking, at the time of signing up, that the target city is actually covered.

Choosing an approved business-address provider: the criteria that matter

Whether the activity is regulated or not, choosing a registration provider should never be left to chance. A business-address company must hold a prefectoral approval, issued by the prefect of the relevant department (or the prefect of police in Paris), valid for six years. The prefect has two months to rule on an approval request, and the company's directors must meet strict good-character requirements.

Operating a business-address service without this approval carries a penalty of six months' imprisonment and a 7,500 euro fine, according to the rules outlined by Bpifrance Création. Before signing anything, a liberal professional is entitled to ask to see the provider's approval certificate.

The registration agreement must also meet several conditions:

• be in writing, for a minimum term of three months, renewable by tacit agreement;
• guarantee a room suitable for ensuring the confidentiality needed to keep professional registers and documents;
• be accompanied by a quarterly declaration from the provider to the tax authorities, listing the businesses registered at the address.

Professional lease or commercial lease: which fits your activity?

Another specific feature of liberal professions: when physical premises are needed (a medical practice, a consulting office receiving clients), a professional lease is often a better fit than a standard commercial lease. Designed specifically for liberal activities, it has a minimum term of six years but offers more flexible termination terms than the standard nine-year commercial lease, though it does not grant the same ownership-like commercial rights. The choice between the two depends mainly on the nature of the activity, the need for stability, and medium-term plans to transfer the business.

Practical steps to register the address of a liberal activity

In most cases, the process follows the same broad steps, whatever the profession:

1. Check whether the profession is regulated and, if so, consult the rules of the relevant professional body before signing anything.
2. Select an approved provider (a business-address company, a business center, or, within legal limits, registration at a personal home) and request the approval certificate.
3. Sign a written registration agreement for at least three months, and keep the registration certificate provided by the provider.
4. Declare the address when registering the business or, in case of a change, update it with the relevant registry, and inform the professional body if required.
5. Update all official documents: articles of association, letterhead, website, professional platforms.

What about registering at home, is it an option for liberal professionals?

Many liberal professionals start their activity at their personal home, which remains allowed under certain conditions of duration and co-ownership rules. This solution, detailed in our article on registering a business at home, works well for starting an intellectual or consulting activity without receiving the public. It becomes trickier, however, for health professions that see patients, or for lawyers wishing to project a professional image to clients from the very first months of practice.

In Marseille, as in the rest of the PACA region, many self-employed liberal professionals make this choice by default for lack of a clear alternative, even though approved registration solutions, sometimes combined with occasional office space, are now available at accessible rates in that market, as our team sees daily through its business registration support across France.

For liberal professionals operating through a company structure rather than as sole traders, registration questions connect to the broader topic of registering civil and commercial companies, with additional asset-related issues to plan for.

Whatever solution is chosen, the registration address remains a visible part of professional identity, and it can also affect the opening of a business bank account. This point is covered in our article on business registration and professional bank accounts. For self-employed professionals who would rather be guided through these steps than handle them alone, the Majoli team offers dedicated support for business registration, anywhere in France.

Frequently asked questions

Can a self-employed doctor or nurse use a business-address provider?

Yes, for the administrative head office of their structure, but this does not replace the practice location where patients are seen. That location must comply with the applicable ARS standards (accessibility, equipment, safety), regardless of the registration address declared for the company.

Does commercial registration reduce the local business property tax (CFE)?

No. Commercial registration only concerns the administrative and postal address of the business. The CFE is still calculated based on the actual place where the activity is carried out, which may differ from the declared registration address.

Does a lawyer need approval to change their professional address?

In most bars, yes: the address change must be reported to the Bar Council, which checks that the new premises guarantee the confidentiality and professional secrecy required by the profession.

What is the minimum term for a registration agreement for a liberal activity?

The legal minimum term is three months, renewable by tacit agreement, regardless of the nature of the registered activity. The agreement must be in writing and kept on file, since the registration certificate is required when registering the business or for any later change.

How can you check that a business-address provider is properly approved?

Simply ask the provider for their prefectoral approval certificate, valid for six years and issued by the prefect of the department where the registered office is located (or the prefect of police in Paris). A serious provider will share it without difficulty before any agreement is signed.
