Best Bank in Spain for Expats: Santander vs BBVA vs CaixaBank Compared

Why Banking in Spain Is Different, and How to Get It Right

The best bank in Spain for most expats depends on how you bank. BBVA’s no-fee Cuenta Online suits people who live in their banking app, CaixaBank has the largest branch and ATM network for smaller towns, and Santander is the familiar international name. All three expect a NIE (Número de Identificación de Extranjero), your passport and proof of address, and fees change, so check the current tariff.

The good news? Spain has a mature, modern banking sector with several internationally recognizable names. The three biggest Spanish banks, Santander, BBVA and CaixaBank, all have strong expat-facing products, English-language services, and competitive digital platforms. The question is: which bank is right for you, and how do you actually open an account?

This guide covers banking in Spain as an expat: account types, fees, documents, digital banking, a head-to-head comparison of the three major Spanish banks and what changes when you open a business account for your own company.

Understanding the Spanish Banking Landscape

Who Are the Main Players?

Spain’s banking sector is dominated by a handful of large institutions, most of which survived the 2008 financial crisis and subsequent consolidation stronger than before:

• Santander: Spain’s largest banking group worldwide and one of the world’s largest financial institutions by market cap. Headquartered in Santander (Cantabria), it has an enormous international footprint.
  
• BBVA (Banco Bilbao Vizcaya Argentaria): the second-largest Spanish banking group, with particularly strong digital banking infrastructure and a significant presence in Latin America.
  
• CaixaBank: Formed through the merger of several Spanish savings banks (cajas), CaixaBank has been the largest bank within Spain by loans and deposits since its 2021 merger with Bankia, and it has the broadest branch network across the country.
  
• Banco Sabadell: A Catalan bank popular with SMEs and English speakers (especially in Valencia and the Costa Blanca).
  
• ING Spain: The Dutch bank operates in Spain with a fully digital, no-fee model that’s popular with younger expats.

For most expats, the choice comes down to Santander, BBVA or CaixaBank, with ING as a strong digital alternative.

Resident vs Non-Resident Accounts

One of the most important distinctions in Spanish banking is between resident and non-resident accounts (cuenta de no residente vs cuenta de residente). This affects:

• The documentation you need to open an account
  
• The products and services available to you
  
• Your tax reporting obligations (more on that in the FEMA/RBI section)

If you hold a valid residency permit (TIE card) or have registered on the Padrón (municipal register), you are a resident for banking purposes. If not, including while you are still applying, you’re non-resident.

What Documents Do You Need to Open a Bank Account in Spain?

For EU/EEA Citizens

• Valid passport or national ID card
  
• NIE (Número de Identificación de Extranjero) obtained from a police station or foreign nationals’ office
  
• Proof of address (utility bill, rental contract, or Padrón certificate)
  
• Proof of income or employment (in some cases)

For Non-EU Citizens

• Valid passport
  
• NIE (mandatory)
  
• Visa documentation (student visa, work permit, digital nomad visa, etc.)
  
• Proof of address in Spain
  
• Additional source-of-funds documentation may be required

Can You Open a Bank Account Without a NIE?

Technically, yes, but it’s increasingly rare. Some banks (particularly online banks) will allow you to open a non-resident account with just a passport, but the major high-street banks now almost universally require a NIE. The exception is if you can demonstrate you’re actively in the process of obtaining your NIE (e.g., you have an appointment confirmation).

Santander Spain: The International Giant

Overview

Santander is the obvious choice for expats coming from the UK, Ireland, Latin America, or the US, where the brand is already familiar. In Spain, it operates thousands of branches nationwide, has a dedicated international banking division, and offers good English-language support.

Key Products for Expats

English-Language Support

Santander offers English-language customer service through its general helpline, though wait times can vary. Its app and online banking portal are available in English. For complex matters (mortgages, investment products), you may need a Spanish-speaking advisor unless you specifically request English support.

Digital Banking

Santander’s Spanish app is solid, offering instant transfers (Bizum), card freezing, spending analytics, and mobile cheque deposits. Its Openbank subsidiary (a digital-only bank) is actually headquartered in Spain and is worth considering for tech-savvy expats who want a purely digital experience.

Fees and Charges

• No monthly fee if you receive a payroll of €600+/month or maintain a minimum balance of €3,000
  
• ATM withdrawals: free at Santander ATMs; €2-4 fee at other Spanish ATMs
  
• International transfers: €3-15 depending on destination and amount
  
• Currency exchange: 1-3% spread on transactions abroad

Pros and Cons of Santander for Expats

BBVA Spain: The Digital Banking Pioneer

Overview

BBVA has consistently led Spanish banking in digital innovation. It was one of the first European banks to launch a fully mobile-first banking experience, and its app is built for people who rarely visit a branch. For tech-savvy expats, particularly those from Latin America where BBVA has a strong presence, it’s a natural choice.

Key Products for Expats

English-Language Support

BBVA has significantly improved its English-language capability in recent years. Its app has a full English interface, and its customer support line offers English-speaking agents (though you may need to get through a Spanish-language menu first). BBVA’s international transfers are handled through its global infrastructure, which makes them efficient.

Digital Banking: Spain’s Best?

BBVA’s app is genuinely impressive. Features include:

• Real-time spending categorization and budget tracking
  
• Bizum instant payments (the Spanish P2P payment system)
  
• Carbon footprint tracking for purchases
  
• Integrated investment and savings products
  
• Virtual card creation for online shopping
  
• Voice-activated transactions

If app-first banking matters most to you, start with BBVA and compare its app with ING and imagin before you commit.

Fees and Charges

• Cuenta Online: completely fee-free with no conditions
  
• ATM withdrawals: free at BBVA ATMs; €0.65-2 at other ATMs (Cuenta Online)
  
• International transfers: competitive via SWIFT/SEPA
  
• No minimum balance requirement on the main account

CaixaBank: The Branch Network Champion

Overview

CaixaBank has more branches in Spain than any other bank, with more than 4,500 across Spain and Portugal in 2025. This makes it the default choice for expats living outside of major cities, particularly in rural areas, small towns, or coastal communities where Santander and BBVA have a thinner presence. CaixaBank was formed through a series of mergers involving regional savings banks (cajas), which means it has deep roots in local communities across Catalonia, Valencia, and the Balearics.

The CaixaBank Welcome Account

• Dedicated international customer service team
  
• Account opening without Spanish language requirement
  
• English, German, French, and other language support
  
• Immigration service referrals (NIE assistance, etc.)

imagin: CaixaBank’s Digital Brand

It doesn’t require a branch visit: you can open your account entirely through the imagin app.

Fees and Charges

• Monthly fee: waived with payroll, pension, or €600+ monthly inflow
  
• ATM withdrawals: free at CaixaBank ATMs (Spain’s largest ATM network)

Alternative: Online Banks for Expats in Spain

ING Spain

ING operates in Spain with a fully fee-free model. No monthly charges, no minimum balance, and free ATM withdrawals at any ATM in Spain (up to 5/month). Its app is available in English and Spanish. The main limitation is the lack of physical branches: customer service is entirely by phone and chat.

N26 and Revolut

While not Spanish banks, N26 (German) and Revolut (UK/Lithuanian) are widely used by expats in Spain. Both offer Spanish IBANs, excellent exchange rates, and strong mobile apps. However, they are not regulated by the Banco de España, which means your deposits are not covered by Spain’s Deposit Guarantee Fund (FGD); they’re covered up to €100,000 by their home country’s equivalent.

Tax Implications of Your Spanish Bank Account

Holding a bank account in Spain has tax implications that many expats overlook:

• Interest income from Spanish accounts is taxable in Spain (at 19-30% depending on amount)
  
• Non-residents have 19% tax withheld on interest by the bank, capped at 15% for Indian residents under the India-Spain DTAA
  
• Under CRS, your Spanish bank reports your account balance and income to Spanish tax authorities, who share it with your home country’s tax authority, including India’s
  
• Modelo 720: Residents with overseas assets exceeding €50,000 must declare them annually, though penalties for non-declaration have been significantly reduced following a 2022 EU court ruling

Conclusion: Which Spanish Bank Is Best for Expats?

There’s no universal answer: the best bank in Spain for expats depends on your situation:

• Best overall for fee-free digital banking: BBVA Cuenta Online
  
• Best for rural or coastal expats: CaixaBank (largest branch/ATM network)
  
• Best for international brand familiarity: Santander
  
• Best fully digital option: imagin by CaixaBank or ING Spain
  
• Best for temporarily banking without all documents: ING or Revolut as a bridge

Whatever you choose, get your NIE first. It opens up full banking in Spain and much of your day-to-day life as an expat there.
