Opening a Business Account: 2026 Document Checklist

Quick answer. To open a business account in France in 2026, a company must gather five document families: directors' ID, articles of association, proof of registered office, beneficial owner declaration and, at incorporation, the share capital deposit. A complete file triggers the certificate of capital deposit, a mandatory registration document, often within 48 to 72 hours.

Opening a business account is rarely what worries founders. Yet it is the step that most often stalls an incorporation timeline. The bank does not simply ask you to prove who you are: it applies legal know-your-customer obligations that turn the opening into a genuine document review. An outdated proof of address, a poorly identified beneficial owner or an expired ID card, and the capital deposit is suspended, which mechanically delays registration.

The stakes are concrete: until the account is open and the capital deposited, no certificate of capital deposit is issued, and without it your registration file stays incomplete. In our company formation engagements, we regularly see businesses lose one to two weeks on this single point. The purpose of this checklist is to break that domino effect.

The bank is not being overly cautious: it is executing a legal duty. Under articles L561-2 and L561-5 of the French Monetary and Financial Code, every regulated institution must, before entering a business relationship, identify its client and the beneficial owner, then verify these elements against probative documents. This is what is called KYC (know your customer) and the AML-CFT framework (anti-money-laundering and counter-terrorism financing).

In practice, opening a business account is an entry control. The bank seeks to understand the legal structure, identify who really controls the company and assess the project's risk profile (sector, expected flows, international exposure). This logic explains why a file that looks simple to the founder can generate several rounds with the compliance team.

It also explains why the obligation to hold a business bank account is not merely a matter of management convenience: for a company with share capital, the dedicated account is the very condition for depositing the funds.

The required items fall into five families. The detail varies between institutions, but the core stays stable. Here is the checklist to prepare before any account-opening appointment.

• Identity of directors and shareholders: valid ID (national card, passport or residence permit) of the legal representative and each relevant shareholder, both sides, legible.
• Personal proof of address of the legal representative, in practice less than three months old (utility bill, rent receipt, tax notice).
• Articles of association dated and signed (draft before registration, final version afterwards).
• Proof of registered office: commercial lease, domiciliation contract, or the director's own proof of address if the office is at home.
• Beneficial owner declaration and information on the capital breakdown.
• Kbis extract or filing receipt depending on whether the company is already registered or still being formed.

At incorporation, order matters as much as the list. The account first receives the capital, which triggers the certificate of capital deposit, itself indispensable for registration. Once the company is registered and the Kbis extract obtained, the funds are released and the account becomes fully operational.

This is the point that surprises founders the most. The beneficial owner is the natural person who holds, directly or indirectly, more than 25% of the company's capital or voting rights, or who exercises control by other means. The bank must identify this person under its vigilance obligations, and the company must also declare them to the register of beneficial owners (RBE) through the INPI single window.

This declaration is not a side formality. It must be made at the time of registration, and any later change (share transfer crossing the 25% threshold, capital increase, inheritance) must be declared by an amending filing within 30 days. The framework is set by articles L561-45-1 to L561-50 of the Monetary and Financial Code.

The stakes hardened sharply in 2026. Since 28 May 2026, a missing or inaccurate beneficial owner declaration exposes the legal representative to a fine of up to 200,000 euros and a management ban of up to 15 years. The beneficial owner declaration therefore deserves real rigour, not a rushed entry.

The capital deposit is the primary reason for the account at incorporation. Funds corresponding to cash contributions must be deposited within eight days of receipt into a blocked account in the name of the company being formed, or with a notary (article R223-3 of the Commercial Code). These funds stay blocked until registration, then are released upon presentation of the Kbis.

The fraction to release immediately depends on the legal form, a point often poorly anticipated.

A typical opening procedure unfolds as follows:

1. You prepare the draft articles of association and the capital breakdown between shareholders.
2. You assemble the complete KYC file and send it to the chosen institution.
3. The bank opens the account and receives the cash contributions.
4. It issues the certificate of capital deposit, a mandatory registration document.
5. You register the company through the INPI single window and obtain the Kbis.
6. On presentation of the Kbis, the funds are released and the account becomes operational.

Auto-entrepreneur and micro-business. There is no capital to deposit, hence no certificate of deposit. The obligation is limited to a dedicated activity account above a certain turnover, and the bank mainly requires identity and proof of activity (Sirene registry status notice).

Non-resident director or shareholder. KYC checks are reinforced. The bank may request translated documents, a tax certificate from the country of residence and more explanation on the source of funds. If cross-border accounts or flows are involved, anticipate the reporting side too: we cover this in our article on opening a business account abroad and the 3916 declaration.

Holding company or multi-tier structure. As soon as a legal entity holds shares, the bank traces the ownership chain up to the natural persons exceeding 25%. Prepare a clear ownership chart: this document often saves a week.

The underestimated risk#

The most common blocker is not a missing document but an inconsistency between documents. A registered office address that differs between the articles of association, the domiciliation proof and the single-window declaration is enough to trigger a manual review. Likewise, a beneficial owner declared to the bank but inconsistent with the capital breakdown in the articles extends processing. File consistency matters more than file volume.

What the bank really looks at#

Beyond checking documents, the institution assesses risk. A sensitive sector (crypto, international trading, gambling), projected flows that are high relative to capital, or an opaque ownership structure trigger enhanced vigilance. Presenting a clear project with a coherent forecast speeds up the opening as much as a valid ID.

Our reading#

Opening a business account is not an isolated administrative step: it is the first test of your company's documentary solidity. A clean file at this stage signals controlled governance, and it smooths everything that follows, from the capital deposit to the first VAT return. Conversely, a sloppy file creates a delay that spreads to registration, supplier contracts and sometimes the first invoice.

Recently, the founder of a technology services company being formed approached us after two successive opening refusals. The issue was neither the project nor the funds, but an ownership chain through a personal holding that had not been spelled out. Once the ownership chart and the beneficial owner were clarified, the account was opened and the capital deposited within days. The missing piece was not a document: it was clarity.

As accountants registered with the French professional Order, we apply these same AML-CFT vigilance duties to our own client files. This dual perspective lets us anticipate what the bank will look for and prepare the file in the right order, in connection with the choice between SARL and SAS that drives the fraction of capital to release.

Hayot Expertise tip. Build your KYC file once, complete, before the first bank contact. Check three consistencies before sending: the registered office address identical everywhere, the beneficial owner aligned with the capital breakdown in the articles, and non-expired IDs. If you hesitate on the legal form, settle it before depositing: it changes the required capital fraction.
