Is a Business Bank Account Mandatory for My Company in 2026?

Quick answer. Yes for companies (SASU, SARL, SAS, SA): a bank account in the company's name is mandatory from incorporation for the deposit of share capital. For micro-entrepreneurs, a dedicated account (not necessarily a paid "pro" account) is required only if turnover exceeds €10,000 over two consecutive calendar years. Below that threshold, a dedicated account remains highly recommended.

The question of whether a business bank account is mandatory remains a source of confusion among founders and business leaders in France. Three distinct legal and tax regimes coexist, each with its own banking requirements. At Hayot Expertise, we observe that approximately 30% of new clients begin by mixing their professional and personal funds, which creates three problems: insufficient accounting traceability, risk of adjustment by URSSAF/tax authorities during an audit, and practical inability to manage the company's cash position.

For any legal entity (company), the obligation is absolute and from the outset.

Legal basis: the French Commercial Code requires cash contributions to be deposited in a blocked account opened in the name of the company being formed, before registration. Holding an account in the company's name is therefore not a mere recommendation—it is a mandatory step of incorporation.

In practice:

1. Before registration with the RCS (Business Register), you must open a blocked account with an authorized bank to deposit the share capital in cash (equity contributions).
2. This blocked account holds the funds until the company is registered with the RCS.
3. Once registered, the account is unblocked and functions as the company's current account.
4. This account must remain in the company's name; no third party (including a sole shareholder) may redirect it for personal use.

Hayot Expertise analysis: A SASU founder recently asked us whether he could use his personal account to deposit the capital (€1,000) before receiving the RCS registration certificate. Although technically debatable during the interim phase between incorporation and registration, this practice exposes to three risks: (1) the tax authorities may contest the timing of deductibility for certain start-up expenses, (2) a bank may refuse to hold the funds without a real account identified in the future company's name, (3) in case of disagreement with a co-founder who disappears before registration, each party's rights over these funds become unclear. Opening a dedicated account costs nothing additional — most banks propose this as part of the capital deposit process.

For this category, the obligation is conditional and depends on a threshold.

Legal basis: The PACTE Act of May 2019 relaxed the obligation by making it subject to a turnover threshold. Article L. 133-6-8-4 of the French Social Security Code states that a micro-entrepreneur must open a bank account dedicated to professional activity if turnover exceeds €10,000 over two consecutive calendar years.

Decoding the threshold:

• €10,000: annual threshold (from 1 January to 31 December, reported to URSSAF/tax authorities).
• Two consecutive years: the obligation activates only if you exceed €10,000 in year 1 and in year 2. If you exceed in year 1 but drop to €8,000 in year 2, no obligation applies. If you exceed in years 1 and 2, the obligation becomes effective during year 3.

Important: the obligation refers to a "dedicated bank account," not a "professional account." In practice, you may use an ordinary current account (at your personal bank) provided it is distinctly identified in your micro-business name (e.g., "John Doe, Sole Trader" or "John Doe, EIRL"). You are not required to pay a monthly "Pro" package if you just exceed the threshold.

For a sole trader outside the micro regime, no general legal obligation exists to open a professional account. However, separating funds is strongly recommended for three legal reasons.

First reason: accounting traceability. You are required to maintain complete accounting records if you have exceeded the micro thresholds (since the December 19, 2018 ordinance, sole traders have the same obligations as single-member LLCs). A dedicated account facilitates justification of each transaction and avoids costly accounting reconstructions during an audit.

Second reason: personal liability separation. Although the sole trader does not benefit from a separate legal entity status, case law and URSSAF consider that a dedicated professional account demonstrates an intent to separate assets—this strengthens your position in disputes with creditors.

Third reason: deductibility of expenses. Costs directly related to account management (monthly fees, transfer fees, professional loan interest) are deductible only if clearly attributable to professional activity. A mixed personal account complicates this demonstration.

Hayot Expertise advice. Whether you are a micro-entrepreneur or sole trader, opening a dedicated account from day one costs nothing at creation and avoids a complex bank migration later when turnover exceeds thresholds. Most banks offer simplified current accounts (free or €3–5 monthly) for small turnovers. This minimal investment will save your accounting firm hours of reclassification if an URSSAF audit asks you to justify the allocation of expenses.

1. Exception for commercial activities (micro-entrepreneurs).

Even if your turnover is below €10,000, if you conduct commercial activity (buying and selling goods, restaurant service on premises, etc.), the obligation to have a dedicated account applies immediately, without waiting for the €10,000 threshold. Service activities (consulting, freelancing, etc.) are not subject to this exception.

2. Blocked account vs. current account: do not confuse.

When creating a SASU or SARL, the bank opens two successive accounts: the blocked account (during the interim phase between incorporation and registration) and then the professional current account (after registration). Some founders pay unnecessary closure fees because they forget that the blocked account automatically transforms into a current account. Check with your bank what fees apply to each phase.

3. Joint liability in case of fraud.

If you mix funds and a third party lends you money believing it is a professional loan, but the funds end up in your personal account and are used to buy an undeclared company car, the tax authority may recharacterize the arrangement and disallow the expense. A dedicated account demonstrates intent to separate assets.

4. Right to account (inalienable right).

If a bank refuses to open a professional account (rare refusal, but it has happened for sectors deemed high-risk), you may invoke the right to account (Article L. 312-1 of the French Monetary and Financial Code). The Banque de France will designate an institution that must open an account with basic banking services. This right applies to micro-entrepreneurs and companies alike.

Over the past four years at Hayot Expertise, we have supported over 500 business founders. A recurring situation: a SASU founder launches without a dedicated account, thinking "I'll open one in three months." Three months later, he has transferred €15,000 to his personal account, withdrawn his salary twice without clear documentation, and purchased a business computer on that account as well. When the time comes to file the annual accounting statement or make a tax adjustment, our team must reconstruct each transaction—a mission taking 6–8 hours and charged to the client, which could have been avoided by thirty minutes of account opening.

For micro-entrepreneurs who gradually climb and exceed the €10,000 threshold in year 2, it is the same: changing banks after three years of mixed transactions requires complete reclassification of all entries and exits, and sometimes reveals retroactive VAT anomalies. A dedicated account from day one (even a free one) saves you this reclassification work.

• Companies (SASU, SARL, etc.): absolute legal obligation to open an account in the company's name, from before registration (blocked account).
• Micro-entrepreneurs: obligation for a dedicated account only if turnover > €10,000 over two consecutive years; exception if commercial activity.
• Sole traders outside micro regime: no legal obligation, but separation strongly recommended for accounting traceability and expense deductibility.
• Minimal cost: most banks offer dedicated current accounts free (or €3–5 monthly) for small turnovers.
• Right to account: if a bank refuses, the Banque de France can mandate another institution.
• Asset separation: the dedicated account demonstrates clear distinction between personal and professional assets.
• Later migration: changing banks after three years of mixed accounts is far more expensive in accounting reclassification than opening one from day one.
