Chartered accountant in Paris 2026: missions, obligations and how to choose the right firm

Quick answer. A Paris-based chartered accountant registered with the French Order of Chartered Accountants (OEC) has been, since Ordinance n° 45-2138 of 19 September 1945, the only professional authorised to keep the accounts of a third party for remuneration. In 2026, the obligations cover professional ethics (OEC Code of Conduct), a written engagement letter, professional secrecy, mandatory professional indemnity insurance and anti-money-laundering duties to Tracfin (article L. 561-2 of the French Monetary and Financial Code). The right firm for a Paris-based business owner combines registration with the Order, sector specialisation, an ethics-driven methodology and fees aligned with the actual scope.

At Hayot Expertise, a firm registered with the French Order of Chartered Accountants of Paris Île-de-France and based at 50 avenue Hoche in the 8th arrondissement of Paris, we meet every week with directors of very small businesses and SMEs who discover, after a bad experience, that their previous provider was actually not registered with the Order — or that the engagement letter did not cover the work that was really expected. The boundary between consulting, bookkeeping and the compilation of financial statements is strictly regulated in France, and a director who picks a firm in 2026 without understanding this framework takes unnecessary risks: poorly covered civil liability, financial statements that cannot be relied upon, anti-money-laundering exposure, and even invalidation of the annual tax return package.

Paris concentrates almost 4,500 chartered accountants registered with the OEC Paris Île-de-France regional council according to 2025 OEC data, which is more than a quarter of the national total — a direct consequence of the density of head offices, the presence of the Paris-East branch of the DGFiP (French tax authority) and the vibrant startup ecosystem. This abundance complicates the choice: firms do not all process the same type of files, and specialisation has become the discriminating criterion. This guide explains what the law requires from your chartered accountant, what they do beyond the legal minimum, and how to evaluate a Paris-based firm in 2026.

The chartered accountant is a regulated liberal professional who holds the Diplôme d'expertise comptable (DEC), the State-issued chartered accountancy diploma, and is registered on the Roll of the French Order of Chartered Accountants. The profession is governed by Ordinance n° 45-2138 of 19 September 1945, as amended, which also created the Order. Article 2 of that ordinance reserves an exclusive competence over three families of acts:

• Keeping, centralising, opening, closing, supervising, correcting and consolidating the accounts of a third party on a habitual basis and for remuneration;
• Reviewing and assessing the accounts of companies and bodies with which the professional is not bound by a contract of employment;
• Certifying the regularity and sincerity of balance sheets, profit and loss accounts and any related accounting situations.

Any individual or legal entity who would carry out one of these acts for remuneration without being registered on the Roll commits the offence of illegal practice of the profession, punishable by a fine and, in case of repeated offence, by administrative closure. You can check the registration of a firm on the official directory annuaire.experts-comptables.org, run by the National Council of the OEC.

Not to be confused with the statutory auditor (CAC). The CAC carries out a statutory and independent audit mission (certification of the financial statements), governed by the Professional Practice Standards (NEP) of the Compagnie nationale des commissaires aux comptes. The auditor cannot advise the audited client. By contrast, the chartered accountant carries out contractual bookkeeping and advisory engagements. The same professional may be registered on both rolls, but never for the same entity.

Beyond the 1945 Ordinance, the Code of Conduct of professionals in chartered accountancy (approved by decree n° 2012-432 of 30 March 2012) imposes six structuring obligations:

1. Independence and conflicts of interest — a chartered accountant cannot accept an engagement that would compromise their professional judgement (art. 9 of the Code).
2. Competence and continuing professional development — minimum 40 hours per year, validated by the Order.
3. Absolute professional secrecy on the facts, acts and documents that come to their knowledge (art. 226-13 of the French Criminal Code).
4. Mandatory written engagement letter signed by both parties before the work starts (art. 11 of the Code of Conduct).
5. Professional indemnity insurance subscribed individually and at firm level (art. 16 of the Code).
6. Duty to advise: alert the client to any tax, social or legal risks identified (contractual civil liability, art. 1231-1 of the French Civil Code).

The engagement letter is the legal cornerstone of the relationship. Without it, the firm's remuneration is on shaky legal ground and disciplinary liability is engaged. It must precisely define: the nature of the work (compilation engagement, limited review, contractual audit, advisory engagement), the respective obligations, the fees (hourly rate, fixed fee, indexation conditions), the schedule, the duration and the conditions for termination. Our dedicated article on the rupture de mission à l'initiative de l'expert-comptable details the formal procedure.

Since the transposition of the 5th European AML directive, article L. 561-2 of the French Monetary and Financial Code expressly subjects chartered accountants to the fight against money laundering and the financing of terrorism (LCB-FT). In practice, the firm must:

• Identify the client and the beneficial owner (Beneficial Owners Register, identity check, proof of address, RBE INPI register);
• Carry out a risk classification for each client (low, standard, high) on the basis of an internal grid;
• Keep supporting evidence for five years after the end of the business relationship;
• Report to Tracfin any suspicion regarding the origin of funds, their destination or the economic consistency of an operation (electronic suspicion declaration through the ERMES portal);
• Train staff every year on money-laundering typologies;
• Maintain an internal register of enhanced due diligence decisions and declarations made.

Tracfin published in 2024 an operational guide for chartered accountants which reminds that the profession is one of the main contributors to AML reporting in France (more than 1,700 declarations in 2023). Failure to comply exposes the firm to disciplinary sanctions from the Order, administrative penalties (up to EUR 1 million) and, in cases of complicity, criminal sanctions.

1. Bookkeeping, review and compilation engagement#

A historic mission, but one undergoing rapid transformation. The firm carries out the monthly or quarterly bookkeeping: purchase and sales invoices, bank reconciliations, account matching, fixed assets, VAT. In 2026, electronic invoicing (impots.gouv.fr) reshapes this mission: from 1 September 2026, all VAT-liable companies must be able to receive electronic invoices in a structured format through an approved platform (PA). At year-end, the firm prepares the annual financial statements (balance sheet, income statement, notes) under the French General Accounting Plan (ANC regulation 2014-03) and the annual tax return package (2065-IS, 2050-2059, or BNC/BIC for self-employed regimes).

A chartered accountant can issue three different types of reports:

2. Tax advice and the tax compliance examination (ECF)#

The chartered accountant is a top-rank tax adviser. They help the business choose its tax regime (corporate income tax IS or personal income tax IR), optimise its VAT, structure its deductible expenses, anticipate IS instalments and statutory deadlines, secure exceptional operations (sale of business, contribution-then-sale under art. 150-0 B ter CGI, restructurings) and respond to tax audits. Since 2021, they may also carry out an Examen de conformité fiscale (ECF) on ten key tax points (tax regime, VAT, CFE local business tax, etc.), enforceable against the tax authority and which reduces the risk of reassessment. For a complete overview, see our veille fiscale 2026 du dirigeant.

3. Payroll, social charges and HR management#

Payroll management (pay slips, calculation of URSSAF social contributions, monthly DSN nominative social declaration, taxes on salaries) has become a mission with high compliance stakes, especially since the introduction of pay-as-you-earn income tax and the increasing complexity of the minimum wage structure. The chartered accountant also supports recruitment (permanent contracts CDI, fixed-term contracts CDD, apprenticeship), day-to-day management (absences, leave, mutual termination agreements rupture conventionnelle), and declaration duties (DSN, DOETH disabled-worker declaration, AT/MP occupational accident reporting).

4. Legal work and annual corporate secretarial duties#

Every company must hold an Ordinary General Meeting approving the financial statements within six months of year-end, draft the minutes, and file the accounts with the commercial court registry (art. L. 232-21 et seq. of the French Commercial Code). The chartered accountant handles these formalities as part of the annual corporate secretarial mission and can advise on exceptional transactions (share capital increase, share transfer, conversion, creation of a patrimonial holding company). Our secrétariat juridique annuel et conseil corporate service coordinates this mission with the director's corporate lawyer when needed.

5. Financial steering and financial advisory#

Beyond the annual accounts, the modern firm drives performance: monthly dashboards, forecasts (budget, cash flow, business plan), profitability analysis by product or by client, bank support (financing file, covenant negotiation). This dimension is central for growing Paris-based SMEs and often makes the difference between a "bookkeeping plus year-end" firm and a "growth partner" firm.

No, no piece of legislation makes a chartered accountant compulsory for a commercial company in France. The law distinguishes three practical levels:

The obligation becomes indirect as soon as a bank, an investor, a fund, a statutory auditor or a public client requires it in its terms of reference. To size the right level of engagement, see our simulateur de tarif expert-comptable.

1. Verify registration on the Roll of the Order at annuaire.experts-comptables.org (Paris Île-de-France regional council). A non-registered firm has no legal right to practice.
2. Assess sector specialisation by typology (startups, patrimonial SCI, holding company, liberal profession, e-commerce, association). Our article expert-comptable par secteur d'activité 2026 lists the main specialisations on the market.
3. Ask for the standard engagement letter and check the scope (compilation, payroll, legal, advisory), the fee revision rules and the termination conditions.
4. Identify the dedicated contact: signing partner, lead collaborator, contractual response time, frequency of review meetings.
5. Evaluate mastery of 2026 digital tools: approved e-invoicing platform, bascule Pennylane or equivalent, OCR (Dext, Yooz), banking connectors (Open Banking).
6. Ask for two client references in your sector and size segment. A serious firm provides them within eight days.

Our méthode complète pour choisir un cabinet comptable en 2026 details each of these steps with a scoring grid.

• SASU with a sole shareholder: needs centred on the tax return package, dividend-versus-salary trade-off and the personal income tax return. A firm with monthly fixed fees is sufficient (see SASU vs EURL).
• Family patrimonial SCI (real estate civil company): structural choice between IR and IS regimes, simple compilation engagement, transmission planning. Generalist firm with patrimonial competence.
• Subsidised non-profit association (loi 1901): EUR 153,000 public subsidies threshold triggering the appointment of a statutory auditor; chartered accountant indispensable to justify the use of public funds.
• Active multi-subsidiary holding: needs consolidation, tax integration regime, group steering. Specialised firm with a multi-disciplinary team.

• Choosing solely on the monthly price without looking at the scope of the engagement, which leads to mid-year contractual amendments.
• Not signing an engagement letter or signing one that is too generic, which is risky in case of dispute.
• Confusing online firm and registered firm: some digital players play on ambiguity; always verify registration on the Roll of the Order.
• Ignoring the AML dimension: a firm that asks for no identity or beneficial-owner documents is failing its statutory duties — that is a red flag on overall rigour.
• Overlooking payroll: an accounting engagement without payroll becomes unmanageable as soon as the first employee is hired and quickly exposes the company to URSSAF reassessments.

Out of the hundred or so initial meetings we conduct each year in Paris, three elements consistently differentiate a satisfied director from a director who changes firm after 18 months.

First element: clarity of scope from the engagement letter onwards. Too many providers sell a monthly flat fee without precisely defining what it covers (how many pay slips? how many invoices recorded per month? what depth of tax advice? is the corporate secretarial work included?). At the first overrun, the client feels trapped by amendments. At Hayot Expertise, we systematically quote a nominal scope and a marginal price beyond it, so that there is no surprise.

Second element: real specialisation, not just marketing positioning. Many Paris firms claim specialisations (startups, real estate, liberal professions) without the critical mass of files or trained partners. The practical test is to ask how many files of the relevant typology are managed, how many years of track record, and which OEC training programmes the team has attended. Our Hoche-street firm deliberately maintains a strong "SME directors and intellectual professions" bias rather than diluting across all segments.

Third element: pedagogy on hidden obligations. A good Paris chartered accountant does not merely file returns; they explain AML duties, the implications of 2026 e-invoicing, the personal liability of the director in case of non-compliance with the closing of accounts, and the mechanics of the ECF. An informed director makes better decisions and stays loyal longer.

Hayot Expertise tip. Before signing an engagement letter in Paris in 2026, always ask for three documents: the certificate of registration on the Roll of the Order, the current certificate of professional indemnity insurance, and the firm's internal AML procedure. A serious firm provides these three documents within 48 hours. A firm that hesitates or stalls already reveals organisational fragility.

• The chartered accountant is governed by Ordinance n° 45-2138 of 19 September 1945: only those registered on the Roll of the Order may keep accounts for remuneration.
• Six ethical obligations structure the practice: independence, competence, secrecy, engagement letter, professional indemnity insurance, duty to advise.
• The AML obligations under article L. 561-2 of the French Monetary and Financial Code impose identification, classification, five-year retention and reporting to Tracfin.
• A chartered accountant is not mandatory for a commercial company, but is almost essential as soon as there are employees, VAT, corporate income tax or fundraising at stake.
• Choosing a Paris firm in 2026 = checking registration, real specialisation, clarity of scope, digital mastery and pedagogy on hidden obligations.
• Three documents to require before signing: certificate of registration on the Roll, current professional indemnity insurance certificate, and the firm's AML procedure.
