Do You Need an Accountant for a Micro-Business in France (and at What Cost)?

Quick answer. No, a chartered accountant (expert-comptable) is not legally mandatory for a micro-entrepreneur in France. You can maintain your own sales ledger and, depending on your activity, a purchase register. However, one becomes strongly recommended if you exceed turnover thresholds (€203,100 for retail, €83,600 for services in 2026–2028), anticipate fundraising, face VAT complexity, or have actual expenses exceeding statutory allowances. Pricing ranges from €800–€2,500 annually with a traditional firm, €300–€800 with a digital-only practice.

The micro-business remains the choice of over 60% of French entrepreneurs. Its main advantage: ultra-simplified accounting. Unlike corporate structures (SASU, SARL, SAS), a micro-entrepreneur does not prepare a full balance sheet or income statement. Article L.123-28 of France's Commercial Code requires only a sales ledger (recording cash receipts by date, description, amount, and customer name) and, for trading activities (micro-BIC), a purchase register (supplier, amount, date).

This simplicity has a hidden cost: no statutory financial statements, no court filing, no legal audit — but also no formalized accounting structure to plan for business growth.

Article L.123-28 of the Commercial Code sets the binding framework. Here are the mandatory requirements:

Critical point: maintaining a sales ledger requires no professional qualification or accounting firm. A spreadsheet, simple bookkeeping software, or mobile invoicing app is legally sufficient. No professional certification is mandatory.

Three categories of situation justify engaging a professional accountant for a micro-business.

1. You approach or exceed turnover thresholds#

The 2026–2028 ceilings (revalued every three years) are:

• €203,100 turnover for retail goods, hospitality, and furnished accommodation (micro-BIC trade).
• €83,600 turnover for service-based trading (BIC) and freelance activities (BNC).

Once you exceed these limits for two consecutive calendar years, you automatically lose micro-business status and must file under the standard tax regime (régime réel). This requires full accounting records (balance sheet, income statement, comprehensive tax schedules) and either corporate tax (IS) for companies or standard income tax (IR) for sole traders.

Your accountant's role: forecast the threshold crossing, recommend the optimal legal structure (should you incorporate as a SASU before exceeding the limit?), and organize the accounting transition to avoid costly catch-up at year-end closure.

2. You exceed the VAT exemption threshold#

The 2026 VAT exemption threshold remains at:

• €85,000 turnover for retail and equivalent.
• €37,500 turnover for services.

Below these, you invoice no VAT (advantageous for clients) but cannot recover VAT on purchases.

Above, you enter standard VAT: each month or quarter, you declare, collect, and remit VAT to the tax authority. This materially impacts both cash flow and accounting complexity.

Your accountant ensures: choosing the right filing frequency (monthly or quarterly?), proper invoice documentation, client communication about the VAT transition, and ongoing threshold monitoring.

3. Your actual expenses exceed statutory allowances#

Micro-businesses use a standard deduction (abattement forfaitaire) against turnover for tax purposes:

• 71% for retail (micro-BIC).
• 50% for services (micro-BIC).
• 34% for freelance/professions (micro-BNC).

Example: freelance consultant with €50,000 turnover → taxable income €50,000 × (1 − 0.34) = €33,000.

The trap: if your real expenses never exceed the statutory allowance (pure freelance, minimal overhead), the allowance favors you. But if you have substantial costs (inventory, rent, insurance, continuous training), you pay tax on inflated profit figures, much higher than your actual bottom line.

Your accountant evaluates: an optional switch to actual profit accounting (possible even while remaining micro-sized). This requires real bookkeeping but can save significant tax over multiple years.

4. You are preparing fundraising or a sale#

Once you seek financing (bank loan, investor, crowdfunding) or plan to sell your business, you need certified accounting records and financial statements. DIY micro-business books rarely satisfy external stakeholders.

Your accountant handles: retroactive setup of proper accounting systems, audit of prior-year micro records, issuance of professional certification, or recommendation to incorporate as a SASU for enhanced credibility.

Managing your own sales ledger is legally permissible. Here are genuine risks often underestimated:

Each of these mistakes costs far more than regular professional support over 2–3 years.

Micro-business with employees#

If you hire staff as a micro-entrepreneur, you face mandatory payroll obligations (pay slips, monthly social filings, employer contributions) beyond simple record-keeping. Professional help is nearly mandatory.

Regulated sectors (hospitality, import-export, financial services)#

Some industries require enhanced accounting controls. Restaurants, hotels, wine sales, travel agencies, and investment intermediaries: check with your trade association.

Multiple income streams or complex activity#

Running both freelance and furnished rental income? Large inventory? Import/export operations? Accounting complexity exceeds the simple "ledger" model.

Imminent threshold approach#

If you project rapid growth (reaching €100k revenue within a year), establish proper accounting from day one rather than scrambling to regularize later.

Important note: pricing varies by region and is not regulated. Paris firms typically charge 20–40% more than provincial practices. Pure SaaS platforms without a dedicated professional advisor cannot certify your records or represent you in an audit.

Option 1: Basic invoicing software (Indy, Tiime, Pennylane Solo)#

• Cost: €30–€80/year.
• Advantage: automates the sales ledger, pre-fills tax forms.
• Limitation: no professional liability, no advice, no audit representation.
• Best for: very simple micro with minimal recurring costs.

Option 2: Non-registered independent bookkeeper#

• Cost: €600–€1,200/year.
• Advantage: cheaper than a qualified accountant.
• Limitation: limited professional liability, no audit representation.
• Best for: not recommended — savings are illusory.

Option 3: Shared responsibility (you + accountant)#

• Cost: €800–€1,500/year.
• Advantage: you maintain day-to-day records, accountant reviews and files annually.
• Limitation: you retain some data-entry burden.
• Best for: highly organized micro-entrepreneur wanting to minimize costs.

Recently, we worked with a micro-entrepreneur in IT services who declined our support for 18 months to save money. He maintained a basic Google Sheet and paper invoice folder. When applying for bank financing, we had to retroactively audit 18 months of records. We found three serious errors:

• One €12k invoice never declared (export omission from invoicing software).
• Marketplace receipts declared net of platform commission instead of the gross amount actually collected.
• Software purchases expensed as current costs instead of capitalized assets.

The remediation bill (audit + correction + advice) came to €3,500. Three years of regular support would have cost €2,400 and prevented all three problems.

Hayot Expertise advice. Do not confuse "legal requirement" with "sound practice." Accountants are mandatory for neither micro-businesses nor even SARLs (except mandatory auditors above certain thresholds). Yet weighing the support cost, error risk, and lost financial opportunity, two of three factors favor minimal professional oversight. You can start self-managed if highly organized; but schedule a first review (often free or low-cost) once you reach €40k revenue or anticipate a structural change.
