Business Bank Account Opening — We Coordinate With the Bank
Every Spanish company needs a corporate bank account before it can be incorporated — here's how the process works for US and UK founders, and what documents your bank will ask for.
We prepare your KYC, FATCA, or CRS documentation, liaise directly with banks experienced in foreign-owned companies, and manage the account through capital deposit and conversion to full operational status.
Why You Need This — and When
A corporate bank account isn't optional paperwork you deal with after your company exists — it's a precondition for the company to exist in the first place. Before a notary will authorize the incorporation deed for a Sociedad Limitada (SL), you need to deposit the minimum share capital into a Spanish bank account and obtain a certificate confirming that deposit. That certificate goes into the incorporation file alongside your company registration paperwork.
This creates a sequencing problem that catches a lot of foreign founders off guard: you need a bank account to incorporate, but many banks are reluctant to open a full operational account for a company that doesn't legally exist yet. In practice, most banks solve this with a provisional or "in formation" account, used solely to hold the capital deposit until the company is registered. Once the Commercial Registry issues the registration, you convert that provisional account into a full operating account, or open a fresh one — the workflow varies by bank.
For non-resident founders, this step often takes longer than expected, so it's worth starting the bank conversation early rather than treating it as a formality to knock out the week before your notary appointment.
Documents & Requirements
Spanish banks apply standard KYC (know-your-customer) checks to every new business account, then layer on additional requirements depending on the nationality and tax residency of the beneficial owners.
Standard KYC documents
Regardless of nationality, expect to provide: NIE numbers for all administrators and significant shareholders, the certificate of name reservation from the Central Commercial Registry, passport copies, proof of address, and — once available — the company bylaws. Banks also commonly ask about the source of the capital being deposited and the intended business activity.
FATCA requirements
US citizens and US tax residents opening a Spanish business account are subject to FATCA. Spanish banks are required to identify US-connected accountholders and report account information to the IRS. In practice this means the bank will ask for a US Tax Identification Number (typically your SSN) and a completed W-9 form, in addition to the standard KYC documents. This applies whether you're a director, a majority shareholder, or both.
CRS requirements
UK nationals and other non-EU, non-US founders fall under the Common Reporting Standard instead. Banks will ask for a tax residency self-certification form declaring where you're tax resident and your relevant tax reference number. It's generally a lighter document burden than FATCA, but it's still a mandatory part of onboarding and shouldn't be skipped or rushed.
The Process, Step by Step
1. Reserve your company name
You need the certificate of name reservation before most banks will even discuss opening a provisional account.
2. Open a provisional account for capital deposit
Using the name reservation certificate and the NIEs of the founders, the bank opens an account restricted to receiving the share capital. You deposit the required minimum, and the bank issues a capital deposit certificate.
3. Complete incorporation at the notary
The capital deposit certificate goes into your incorporation deed. Once signed and filed with the Commercial Registry, your SL is legally formed.
4. Convert to a full operational account
Once registration is confirmed and you have your final CIF (company tax ID), you convert or replace the provisional account with a standard business account — the one you'll actually use for invoicing, payroll, and day-to-day transactions, and which feeds into your ongoing bookkeeping.
5. Set up VAT and tax reporting links
Your operational account will be tied to your VAT (IVA) filings and other periodic tax obligations, so getting the account details right from the start avoids reconciliation headaches later.
Choosing a Bank and What Affects Approval Time
Large Spanish banks — Santander, BBVA, CaixaBank, and Sabadell among them — are the most common choices for foreign-owned SMEs, largely because they have more experience handling non-resident shareholders and multi-jurisdiction compliance checks. Smaller regional banks can be less consistent in how they handle FATCA or CRS documentation, which sometimes means slower approvals.
A few factors that reliably affect how long this takes and what it costs:
- Non-resident ownership. Accounts with non-resident beneficial owners tend to draw closer scrutiny — expect source-of-funds questions and sometimes a request for a short business plan or activity description.
- New company status. Freshly formed companies with no trading history are treated more cautiously than established businesses, which can mean lower initial transaction limits or additional review steps.
- Fees. Business accounts for non-resident-owned or newly formed companies sometimes carry higher monthly fees than accounts for established resident-owned businesses — it pays to compare more than one bank before committing.
- Fintech alternatives. Some founders use EU fintech providers for day-to-day operational banking once the company is running, but a traditional Spanish account is still generally required for the capital deposit and registry steps, so you can't skip a Spanish bank relationship entirely.
FAQ
Can I open a Spanish business bank account before my company is registered?
Yes — this is actually required. You need a provisional account to deposit the minimum share capital and obtain the capital deposit certificate before the notary can complete your incorporation deed. This account is typically converted into a full operational account once registration is finalized.
What is FATCA and why does my bank keep asking about it?
FATCA (Foreign Account Tax Compliance Act) is US legislation requiring foreign financial institutions, including Spanish banks, to identify and report accounts held by US citizens and US tax residents to the IRS. If you're a US person opening a business account in Spain, expect to provide a US Tax ID (usually your SSN) and sign a W-9 form as part of onboarding.
As a UK citizen, do I face the same requirements as US founders?
Not exactly. UK nationals fall under the Common Reporting Standard (CRS) rather than FATCA. You'll need to complete a tax residency self-certification, but the documentation burden is generally lighter than what US citizens face under FATCA reporting rules.
How long does it take to open a corporate account as a non-resident?
It varies significantly by bank and by how complete your documentation is. Provisional accounts for capital deposit can sometimes be arranged in a matter of days once your NIEs and name reservation are in hand; converting to a full operational account after registration adds further time. Non-resident ownership and new-company status both tend to slow the process down.
Can I use an EU fintech account instead of a traditional Spanish bank?
Not for the capital deposit step — Spanish incorporation procedure requires a capital deposit certificate from a bank operating in Spain. Some founders do use EU fintech providers for ongoing operational banking after the company is registered, but a Spanish bank relationship is still necessary at the incorporation stage and often useful afterward for local transactions.
Do all shareholders need an NIE to open the account, or just the directors?
Banks generally require an NIE for administrators and for shareholders with significant ownership stakes, since these are the beneficial owners the bank must identify under KYC rules. If you don't yet have your NIE number, that's usually the first document to sort out before approaching a bank.
