What documents does a bank in Spain ask for to open an account for a newly registered company?

For a newly registered Spanish company—typically an S.L. or S.A.—banks commonly ask for:

• Company NIF (formerly often called CIF), usually the definitive NIF.
• Deed of incorporation (escritura de constitución) and articles/bylaws (estatutos).
• Proof of registration in the relevant Mercantile Registry (Registro Mercantil).
• ID for the administrator, legal representative, and anyone authorized to operate the account—for example, DNI, NIE, or passport.
• Proof of authority to act for the company: the relevant powers (poderes), unless already included in the incorporation deed.
• Beneficial-owner information (titularidad real), identifying who ultimately owns or controls the company.
• The bank’s account-opening, KYC, and tax-residency forms; it may also request details about the company’s business activity, expected transactions, and source of funds.

CaixaBank, for example, lists the company’s NIF, incorporation deed and powers, beneficial-ownership document, Mercantile Registry certificate, and evidence of business activity. Exact requirements vary by bank and by the company’s ownership, representatives, and risk profile. (caixabank.es)

Because the company is newly formed, it may not yet have annual accounts or tax returns; ask the bank what it accepts instead, such as an activity plan, contracts, invoices, or evidence of initial funding. Banks can ask for additional documents during their checks. (aresbank.es)

Practical tip: take the original or a bank-acceptable certified copy of the registered deed, and confirm in advance whether the bank needs a recent registry certificate or any documents translated or legalized—especially if an owner or representative is foreign.

Requirements vary by bank and branch, but for a company that is already registered, the core file is fairly consistent. Expect to provide:

• The company's definitive tax number (CIF/NIF). A provisional number is usually not accepted. Obtain the company's definitive NIF. The provisional one is not enough for most banks.
• Corporate documents. These typically include the deed of incorporation, the bylaws, and a recent Mercantile Registry certificate. One sector guide says the certificate should be less than three months old. Sector guidance lists the company's final NIF, the deed of incorporation, the bylaws and a Mercantile Registry certificate less than three months old, plus identity documents for the beneficial owners.
• Proof of who can act for the company. Banks often want evidence of the administrator's appointment, usually in the bylaws or a power of attorney. For an SL or other entity, banks commonly request the incorporation deed, company tax number, Commercial Registry details, bylaws, administrator appointment, beneficial-owner declaration and evidence of business activity.
• Beneficial ownership documentation. This is the notarial Acta de Titularidad Real. Sources disagree on how strictly it is required. One says it declares who the actual human beings are that own more than 25% of the company. It sounds like overkill, but the bank cannot legally open the account without it. Another says banks may request the company's beneficial ownership act when you open a business account. Ask your bank which it requires.
• Identity documents for representatives and owners. Passports or national ID cards are standard, and foreign nationals usually also need an NIE. Valid passport or national identity card; NIE and, for residents, TIE or EU registration certificate
• Proof of address for the company and the individuals involved. Utility bills or bank statements are common, and some banks want them to be recent. One source says utility bill or bank statement no older than 3 months, in the individual's name.
• Evidence of business activity. Banks often want the company's tax registration showing its economic activity, and the activity code should match across documents. Make sure the one the bank puts in your file matches the one on your tax registration.
• Source of funds and a business description. Some banks, especially for newer or foreign-owned companies, ask where the capital comes from and what the business will do. Business-activity narrative, 1-2 pages describing what the company will do, target markets, expected counterparties, monthly transaction volumes, currency mix, and any sector-specific licences.
• Certified and translated documents for foreign-owned entities. Plan for apostilles and sworn translations into Spanish, since foreign documents often need both.

If the company is still being formed, the process is different. The bank must first hold the share capital deposit, because the bank issues a certificate confirming this, which is one of the documents the notary needs to sign the incorporation deed. Since the 2018 reform, however, shareholders can declare their contributions in the deed itself, so a bank certificate is not always needed. Since the 2018 reform of the Capital Companies Act, it is no longer mandatory to present a bank certificate to a notary.

Before you go, call or check the website of your chosen bank for its exact list, since branches can ask for more.

Opening a bank account for a newly registered company in Spain (such as a Sociedad Limitada or SL) involves a standardized set of documentation required to comply with Spanish banking regulations, particularly regarding Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements.

While individual bank policies may vary, you will generally need to provide the following documents:

1. Essential Corporate Documentation

• **Deed of Incorporation (Escritura de Constitución):** The notarized document that officially establishes the company.
• **Articles of Association/Bylaws (Estatutos):** These define the company’s rules, purpose, and governance structure.
• Tax Identification Number (NIF): The document proving the company’s tax ID, issued by the Spanish Tax Agency (Agencia Tributaria).
• Registration Proof: Evidence that the company is registered in the Commercial Registry (Registro Mercantil). Banks often request a recent "Nota Simple" (a brief extract from the registry) to confirm the company’s current status and details.

2. Identification of Key Personnel

• Identification Documents: Valid passports or Spanish ID cards (DNI/NIE) for all directors, legal representatives, and shareholders (especially those with significant ownership).
• **Powers of Attorney (Poderes Notariales):** If the person opening the account is not the sole director, they must provide a notarized power of attorney verifying their authority to act on behalf of the company.

3. Additional Requirements & Contextual Documents

• Bank Certificate for Share Capital: If you are opening the account before final registration to deposit the share capital, you will need the specific "in-formation" bank certificate required by the notary.
• **Economic Activity Declaration (Modelo 036/037):** This document informs tax authorities of the company's intended business activities.
• Questionnaires & Due Diligence: Banks will likely ask you to complete forms regarding the company's anticipated turnover, primary business activity, and the origin of funds. They may also ask for information on the Ultimate Beneficial Owner (UBO).
• Proof of Domicile: Some banks may request a utility bill or rental contract as proof of the company's registered address or physical office location.

Important Tips

• The "In-Formation" Process: If you are still in the process of incorporating, the bank will open a specialized account for a "company in formation" (sociedad en constitución). You will deposit the share capital here and receive a bank certificate to take to the notary.
• Non-Residents: If you are a non-resident, the process can be more complex. Ensure all foreign documents are translated into Spanish by a sworn translator and, where necessary, legalized or apostilled.
• Compliance: Banks are strictly regulated; they may request additional documentation depending on the complexity of your company’s structure or if you have international operations. Working with a local gestor or legal advisor is highly recommended to ensure your "corporate folder" is complete and correctly presented.

For a newly registered Spanish company, banks commonly ask for:

• Company tax ID (NIF/CIF)—usually the definitive NIF for an operating account. Some banks may accept a provisional one while incorporation is being completed. ¹⁸
• Notarised deed of incorporation (escritura de constitución) and, if requested, the articles of association (estatutos sociales). ¹³
• Proof of registration with the Commercial Registry (Registro Mercantil). ¹⁵
• Proof of who can act for the company: the administrator’s appointment or current powers of attorney (poderes). ¹³
• ID for the administrator, account signatories and other authorised representatives—typically DNI or NIE, or a passport where applicable. ³⁵
• Beneficial-owner information (titularidad real), identifying the people who ultimately own or control the company. ¹⁵
• Evidence of the company’s business activity, such as a description of the business, project or financial plan. ¹⁸

The exact list varies by bank and account type. Some banks may also request proof of the registered business address or tax/activity documents; a newly formed company may not yet have the VAT or corporate-tax returns requested from established businesses. ³⁴ Check the bank’s list before applying, especially if the company or its owners are non-resident.
