Is an Accountant Mandatory in France? What the Law Says in 2026

Quick answer. French law does not require hiring an accountant. Any business owner can manage accounting independently if they understand and follow the rules. However, certain legal accounting obligations exist (Code of Commerce Article L123-12)—chronological recording, supporting documents, annual accounts according to size thresholds. And depending on your legal structure and turnover, mandatory appointment of an auditor (decree n° 2019-514) may apply, creating a de facto need for external expertise. An accountant is thus not legally mandatory, but becomes nearly indispensable in many cases.

The confusion stems from a simple source: there is an accounting obligation, but no legal obligation to hire an accountant to meet it. These are two different things.

The accounting obligation (Code of Commerce, Articles L123-12 to L123-28) requires every business to:

• Maintain accounting records (journal, ledger, inventory);
• Record transactions chronologically for all operations;
• Retain supporting documents (invoices, contracts, receipts) for at least 6 years;
• Prepare annual accounts (balance sheet, income statement, notes) according to size thresholds.

Hiring an accountant is an optional service. No law mandates it. You can legally manage your accounting yourself, provided you follow accounting rules.

This distinction is crucial. It opens two paths:

1. DIY accounting (Do It Yourself): possible, but requires time, basic training, and acceptance of audit risk.
2. Accountant support: costly, but secures compliance, adds professionalism, and provides professional liability coverage.

Although no law mandates hiring an accountant, several legal thresholds trigger stricter accounting requirements, which make an accountant nearly essential.

Based on your size: simplified or full account presentation#

Every commercial company must prepare annual accounts — balance sheet, income statement, and notes — under Code of Commerce Article L123-12. Company size only determines the level of detail required: the smallest entities benefit from a simplified presentation (Articles L123-16 and L123-16-1; thresholds raised by the decree of 28 February 2024).

A company that does not exceed 2 of the 3 thresholds for its category may present simplified accounts. Above that, full presentation applies — technical work where an accountant proves its worth.

Beyond 2 other thresholds: mandatory appointment of an auditor#

The second dividing line—far more demanding—is the mandatory appointment of a statutory auditor (commissaire aux comptes), whose thresholds were harmonized by the PACTE law (decree n° 2019-514 of 24 May 2019).

Since that reform, all forms of commercial company (SAS, SASU, SARL, SA, SNC…) share the same thresholds:

Appointing an auditor becomes mandatory once a company exceeds 2 of these 3 thresholds at fiscal year-end; the obligation takes effect the following year. Specific rules also apply to parent companies of small groups.

So a SASU generating €2.5M revenue with a small balance sheet and fewer than 50 employees does not require an auditor. However, a company crossing 2 of the 3 thresholds (for example €9M revenue and 55 employees) must appoint one.

Once an auditor is appointed, an accountant becomes de facto essential to prepare accounts for the auditor to review.

Special regimes: self-employment (no accounting obligation)#

Self-employed individuals (formerly micro-entrepreneurs) enjoy a simplified accounting regime. They need not maintain full accounting records. They must only:

• Record revenue (register or simplified logbook, or approved cash register software);
• Retain expense justifications if deductible (rare for self-employed);
• Respect the micro-regime revenue thresholds (€203,100 for goods sales and accommodation, €83,600 for services and liberal professions, in 2026).

Conclusion for self-employed: An accountant is neither legally required nor often useful, unless you plan to switch to full accounting (EIRL or create a commercial structure).

What can go wrong managing accounting alone#

1. Repeated accounting errors → Tax audit adjustments + late-payment interest (0.20%/month, i.e. 2.40%/year; Art. 1727 CGI) + surcharges (10% to 80% depending on severity).

2. Incomplete file at tax audit → Tax authority may estimate income (without your evidence) and assess above actual figures.

3. Mishandled deductible items → VAT miscalculated → VAT assessments + penalties.

4. Late or missing filing of annual accounts → a filing injunction under penalty ordered by the commercial court president, plus a fine (5th-class offence: €1,500, raised to €3,000 on repeat).

5. Lost tax optimization → You pay more tax than necessary. An accountant would spot legal savings (deductible reserves, loss carryforwards, income spreading, etc.).

6. Succession or sale issues → Buyer sees uncertified accounts, potentially viewed as "fragile" by the buyer's lender or accountant. This can devalue the business.

Cases where DIY risk is very low#

• Self-employed with minimal expenses: simple revenue tracking and receipt filing suffice.
• Independent professional with stable revenue and simple structure: no employees, minimal inventory, few fixed assets.
• Small EIRL service business (revenue < €200k): basic accounting possible with good software.

Cases where DIY risk is very high#

• SAS/SARL with employees: payroll is complex, social contributions high, errors costly.
• Structure subject to corporate tax (SARL, SAS, SA): filing the tax liasse is meticulous.
• Activity with intra-EU VAT or excise duties: VAT is a domain where errors are frequent and costly.
• Regulated sector (liberal professions, hospitality, healthcare): specific accounting obligations, criminal exposure if breached.

Mandatory appointment of an auditor#

Once an auditor is mandatory (thresholds exceeded), you must appoint one — in principle by a shareholders' decision — for a six-year term. The auditor, for a fee, will audit and certify the accounts you or your accountant prepared.

At this point, an accountant is not legally required, but becomes de facto essential because:

• The auditor needs properly prepared accounts from reliable bookkeeping;
• If you present hastily prepared accounts, the auditor will issue a "qualified" or "adverse" audit report, alerting creditors and lenders.

SARL with a minority managing partner#

A minority managing partner pays into the general social security regime. If there are other managing partners or members, account review and presentation obligations arise. In such cases, an accountant prevents conflicts and adjustments.

IFRS accounting standards for certain groups#

For groups exceeding certain thresholds, consolidated accounts must follow IFRS. Only an experienced accountant can handle this technical work.

Recently, a small business director (SARL, 15 employees, €850k revenue) came to us after a €32,000 tax adjustment following an audit. For 3 years, he managed accounting alone with basic software. The errors?

• Two expenses incurred but not recorded (pure oversight);
• A provision for litigation never entered in the balance sheet;
• VAT entries reversed for 4 months (credit/debit reversal);
• Expense entertaining entries forgotten (partially deductible, missing from the audit file).

The cost of adjustment would have far exceeded annual accountant fees over 5 years. Moreover, the fact that accounts were not certified prompted the tax authority to reconsider most deductions purely from suspicion.

Our observation: the absence of an accountant is never savings—it is deferred risk. When risk materializes (audit, bank loan, sale, internal review), costs skyrocket, dwarfing any savings made earlier.

Hayot Expertise recommendation. The question "Do I need an accountant?" depends less on law than on acceptable risks. If you run alone, no employees, minimal expenses, and simple structure (self-employed or EIRL), DIY is legally viable. Once complexity rises (employees, VAT, corporate tax, statutory account filing), risks grow exponentially. We recommend a one-hour consultation before deciding: share your current bookkeeping, expectations, and budget. We will assess true risk beyond theory. In 80% of cases, the accountant pays for itself in avoided adjustments and detected optimizations. That is real ROI, not overhead.
