Opening a Spanish corporate bank account: KYC guide for foreign-owned companies (2026)

If your international group is setting up a Spanish subsidiary, the first bottleneck is unlikely to be the notary, the tax office, or the Mercantile Registry — it will be the bank. Opening a corporate account for a foreign-owned entity is the step that surprises international CFOs most by its complexity: what takes a week in the Netherlands, the United Kingdom, or the United States can take four to eight weeks in Spain, require the physical presence of the authorised signatory, and demand documentation that no other jurisdiction asks for.

This guide explains what sits behind that friction (it is not gratuitous bureaucracy: it is compliance with Ley 10/2010 — the Spanish AML Act — and SEPBLAC criteria), what documentation to prepare before approaching any bank, the difference between a traditional bank and a B2B neobank, and how to avoid the mistakes that delay openings most often.

It is aimed at CFOs, controllers and external advisors deploying a Spanish subsidiary of a foreign group or incorporating a Spanish company with non-resident shareholders.

Key takeaways

• Spanish corporate banking applies a robust KYC process governed by Ley 10/2010 (Spanish AML Act on the prevention of money laundering and terrorist financing), supervised by SEPBLAC (Spanish AML supervisor). There are no legal shortcuts and no “friendly banks” that bypass the process.
• For a Spanish company with foreign ownership, the typical timeline is 4 to 8 weeks at traditional banks (Santander, BBVA, CaixaBank, Sabadell, Bankinter) and 5 to 15 business days at B2B neobanks (Revolut Business, Qonto, Wise Business).
• Neobanks solve day-to-day operations at speed but do not replace a traditional bank for payroll, AEAT (Spanish tax authority) and Social Security direct debits, and operations with Spanish counterparties that expect a Spanish IBAN (ES).
• The Spanish company’s NIF (tax identification number) must be issued before starting the account-opening process. No NIF, no bank.
• Ultimate Beneficial Owners (UBOs) holding directly or indirectly more than 25% of capital or voting rights must be identified, with apostilled documentation when they are foreign nationals.
• Physical presence of the authorised signatory at a branch remains the rule at traditional banks. Enhanced video identification is a valid alternative, but not every institution accepts it for foreign-owned companies.
• Having a fiscal representative or advisor with a direct relationship with the bank accelerates the process by 2 to 4 weeks compared with approaching a bank cold.

Why account opening in Spain is slower than in other jurisdictions

Spain has one of the most demanding KYC frameworks in the euro area, and banks apply it strictly. There are three reasons:

Ley 10/2010 and its implementing regulations (RD 304/2014, amended by Ley 18/2022). It requires obliged entities (banks, advisors, notaries, corporate services providers) to identify the customer and the beneficial owner, to apply risk-based due diligence measures, and to document the source of funds. Sanctions for non-compliance are high (up to EUR 10 million or 10% of turnover), so banks act conservatively.

SEPBLAC and supervision. The Servicio Ejecutivo de la Comisión de Prevención del Blanqueo de Capitales (Spain’s Financial Intelligence Unit and AML supervisor) oversees compliance and issues binding technical criteria. The banking industry has aligned with prudent standards in response to this supervision.

Reputational risk and historical fines. Recent sanctions against institutions for KYC failures have made compliance departments particularly demanding with internationally exposed clients, especially when shareholders sit in jurisdictions on the Modelo 232 list (Spanish related-party and tax-haven reporting form) or where corporate structures are complex.

The result: what looks to a foreign CFO like an excess of documentation is, for the bank, the minimum defensible position before a SEPBLAC inspection.

Documentation to prepare before approaching any bank

Account opening genuinely starts when you have the following documents in hand, sworn-translated into Spanish where they are in a foreign language, and apostilled (Hague Convention) or consularly legalised where applicable.

From the Spanish company

• Final NIF (not provisional). Issued by AEAT.
• Deed of incorporation and, where applicable, deed of share purchase if the company is not newly incorporated.
• Current bylaws (estatutos).
• Certificate from the Mercantile Registry (Registro Mercantil) evidencing registration and good standing (typically less than 3 months old).
• Resolution of the management body authorising the account opening and designating the authorised signatory or signatories.
• Modelo 036 / 037 evidencing tax registration and declared activities.

From the foreign parent

• Certificate of registration equivalent to the Spanish Mercantile Registry from its home country (Companies House, KvK, RCS, certificate of good standing, etc.), apostilled.
• Bylaws or certificate of incorporation, apostilled and sworn-translated.
• Identification of the management body: current appointments, apostilled.
• Full shareholding structure traced up to natural persons (UBOs).

From the Ultimate Beneficial Owners (UBOs) — critical

A UBO is the natural person who directly or indirectly holds more than 25% of capital or voting rights, or who exercises effective control by other means (article 4 of Ley 10/2010 and RD 304/2014).

For each UBO:

• Valid passport or national ID (certified or notarised copy).
• Proof of address (utility bill or equivalent, no more than 3 months old).
• CV or professional background (informal, but the bank will request it).
• Source of funds: a declaration with a credible explanation supported by documentation (tax returns, sale-and-purchase agreement, annual accounts, financing prospectus).
• PEP status (Politically Exposed Person): an express declaration.

From the authorised signatory who will open the account

• Identification (valid national ID/passport).
• Notarial power of attorney evidencing authority to open and operate the account, apostilled if foreign.
• Spanish NIE (foreigner identification number) if non-resident: required to sign the bank contract at many institutions.

From the business model

• Business plan or executive summary.
• Estimated transaction volume: expected monthly revenue, number and type of transactions.
• Counterparty countries: main customers and suppliers.
• Evidence of the relationship with the parent: intra-group services agreement, distribution, licensing, etc.

Traditional banks vs neobanks: what each one covers

Traditional banks (Santander, BBVA, CaixaBank, Sabadell, Bankinter)

What they offer:

• Full Spanish IBAN (ES) with the national payment system (SEPA, corporate Bizum at some institutions).
• Direct debit of taxes (forms 200, 303, 111, 115, 216), Social Security contributions and payroll.
• Working capital lines, commercial discounting, factoring.
• Guarantees, sureties and letters of credit.
• Private banking and international tax services (at the larger players).

What they do not offer well:

• Speed of account opening.
• Competitive FX rates and fees.
• Modern API interfaces for ERP integration.

Typical timelines in 2026: 4-8 weeks, depending on the complexity of the shareholding structure and the risk profile. Cases involving UBOs in Modelo 232 jurisdictions, indirect shareholders through trusts, or PEP profiles can stretch to 10-12 weeks.

B2B neobanks (Revolut Business, Qonto, Wise Business)

What they offer:

• Fast digital onboarding (5-15 business days, sometimes less).
• European IBAN: sometimes ES, sometimes from other jurisdictions (LT, BE, FR). Worth checking if you need to use it for AEAT and Social Security direct debits.
• Multi-currency capabilities and competitive FX.
• Modern APIs and ERP connectivity.
• Instant virtual and physical cards.

What they do not offer:

• Sizeable credit lines.
• Complex banking services (sureties, on-demand guarantees).
• Physical branch support.
• In some cases: AEAT tax direct debits (occasional rejections).

Typical timelines: 5-15 business days when documentation is complete. They may decline profiles with shareholders in Modelo 232 jurisdictions or with complex structures.

Operational recommendation

For a new Spanish subsidiary, the optimal setup is usually dual:

• Primary account at a traditional bank (Sabadell or Bankinter are the most agile traditional players for international profiles). Used for AEAT, Social Security, payroll and Spanish supplier direct debits.
• Operating account at a neobank (Qonto and Revolut Business are the most widely used). Used for card spend, FX and cross-border activity.

This setup combines speed with full coverage. Going neobank-only creates problems with AEAT and Social Security further down the line; going traditional-only constrains international operations.

Banks: what to expect from the main players

This assessment is subjective and reflects operational experience with clients in 2024-2026. Policy can shift and individual cases may differ materially.

Mistakes that delay account opening most often

1. Starting the opening without a final NIF. The bank will not open an account without a NIF. Filing for the NIF with AEAT before even choosing a bank saves 2-3 weeks.
2. Apostilles and sworn translations not ready. Securing an apostille in some countries (US, UK) takes weeks. Start the day you sign the deed of incorporation.
3. Poorly documented shareholding structure up to the UBO. If there are intermediate holdings without a certificate at each level, the bank will halt the process. Map the entire chain before the first meeting.
4. Authorised signatory without a Spanish NIE. Some institutions require the signer to hold a NIE to open the account. Apply at the Spanish consulate in the country of residence, or by power of attorney in Spain at the start.
5. Underestimating the source-of-funds question. A vague answer (“initial share capital”) without supporting documentation (transfer, contract, annual accounts of the parent) triggers a request for further information that adds 2-3 weeks.
6. Failing to flag activity with Modelo 232 jurisdictions. If there is a relationship with listed jurisdictions, disclose it from the outset. The bank will find out anyway, and a late discovery breaks the relationship.
7. Approaching the bank without an advisor or fiscal representative. This is the single biggest accelerator. An advisor with existing accounts at the bank opens doors and brings reputational credibility before the compliance department.

Frequently asked questions

Can I open the account without travelling to Spain?
Yes, but with limitations. Some institutions accept enhanced video identification under RD 304/2014, while others still require physical presence. The most efficient approach: the authorised signatory travels once, signs everything, and delegates day-to-day operations digitally.

Can I open the account before incorporating the company?
Not in the company’s name. You can open a capital-contribution account in the founding shareholder’s name to deposit the share capital prior to the incorporation deed. The corporate account itself can only be opened once the NIF has been issued.

What happens if my UBO is resident in a Modelo 232 jurisdiction?
The account can still be opened, but the bank will apply enhanced due diligence (EDD): additional documentation, longer timelines and ongoing monitoring. In some cases the bank may decline, so it is worth having a plan B with another bank.

Which banks are receptive to foreign-owned companies in 2026?
Sabadell, Bankinter and Santander have dedicated teams with a positive disposition. CaixaBank and BBVA are more conservative with new clients lacking a prior relationship. B2B neobanks (Revolut Business, Qonto) are agile but with more limited coverage.

How much does it cost to open and maintain a corporate account?
Opening is usually free or carries a nominal cost. Monthly maintenance: EUR 10-30 at traditional banks, EUR 9-50 at neobanks depending on the plan. Per-transaction fees vary. Working capital lines and guarantees have their own pricing structure.

My account has been under review for 6 weeks with no movement — what should I do?
Prolonged silence usually signals a block in compliance. Request a meeting with the relationship manager and, if there is no response, escalate to the customer ombudsman (defensor del cliente). In parallel, start the process with an alternative bank. Pushing harder rarely accelerates; switching banks sometimes does.

Do I need a Spanish account if my subsidiary only invoices the parent?
Operationally, yes, because AEAT and Social Security require direct debits from a Spanish IBAN (ES) for most filings and contributions. Functionally, yes, because Spanish suppliers (notary, advisor, office lease) expect a domestic transfer.
