Sociedades Limitadas must hold a dedicated business account. Autónomos legally can use a personal IBAN — but the moment you mix client receipts with the weekly Mercadona shop, your accountant is fighting a losing battle. Here is the honest, bank-by-bank guide for expats running an autónomo or SL in Spain.
Get a Business Insurance Quote WhatsApp Our TeamA Sociedad Limitada (SL) is a separate legal person — it owns its money, signs its own contracts and files its own tax returns. Spanish payment services law, built on Ley 16/2009 de Servicios de Pago ↗ and successor regimes, together with corporate and tax obligations, make it impossible to operate properly without a cuenta corriente empresa in the company name and CIF.
An autónomo is different. Legally, you and the business are the same person, so the AEAT does not technically require a dedicated business IBAN. In practice every asesoría begs new autónomos to open one — because the AEAT's Modelo 196 ↗ obliges Spanish banks to report account balances and movements, and a clean ledger of business-only flows makes every IRPF and IVA filing defensible.
The Spanish banking system runs on SEPA, supervised by the Banco de España ↗ and standardised by the European Payments Council ↗. Whether you bank with Santander, BBVA, N26 or Wise Business, the IBAN, transfer rails and adeudo SEPA direct-debit structures are identical. The differences are price, English support and how fussy the bank is about a foreign-passport SL owner.
Before you compare Santander against Wise, you need to understand what a Spanish business account actually does and how the SEPA rails behind it work. These are the six essentials.
A Spanish IBAN is 24 characters: ES + 2 check digits + 4-digit bank code + 4-digit branch + 2 control digits + 10-digit account number. Some Spanish suppliers, utilities and public bodies still refuse non-ES IBANs for direct debits, despite SEPA IBAN discrimination rules outlawing the practice under the SEPA Regulation 260/2012 ↗. A local ES IBAN saves friction.
Standard SEPA Credit Transfer (SCT) settles within one business day for free or near-free across the Eurozone. SEPA Instant Credit Transfer (SCT Inst) clears in under 10 seconds, 24/7/365, up to €100,000 per payment, and is now mandatory for all Spanish banks to receive (and shortly to send) under the EU Instant Payments Regulation. Useful for client receipts and supplier urgency.
Spanish utilities, social security (RETA cuota), AEAT (Modelo 130, 303, 200) and most B2B suppliers prefer to pull money via adeudo SEPA direct debit. You authorise once via a mandate; they debit on schedule. For an SL or busy autónomo this is essential. Personal accounts can do it, but commingling AEAT payments with personal direct debits is exactly where bookkeeping comes unstuck.
Every Spanish bank files Modelo 196 ↗ annually to the AEAT, declaring all account balances, average balances and interest paid. Your declared income on the IRPF needs to reconcile with what your bank told Hacienda. A clean business-only account makes this trivial. A personal account with mixed flows makes it a forensic exercise.
If you take card payments — bricks-and-mortar or e-commerce — you'll deal with a Terminal Punto de Venta (TPV). High-street banks bundle TPV with the account at 0.5%–1.5% per transaction plus monthly rental (€10–€25). Stripe, SumUp, Square and Adyen typically beat them on price but settle to your business IBAN, so the account still matters.
Under the US–Spain FATCA intergovernmental agreement, Spanish banks must report US persons' accounts to the IRS. Many high-street banks refuse to onboard US citizens entirely rather than handle the paperwork — particularly for SL owner-directors. Caixa, Sabadell and (for SLs) BBVA have historically been the most pragmatic. Wise Business and Revolut Business are usually the path of least resistance.
The right bank depends on your structure, your nationality, your turnover and how often you need a branch. These are the patterns we see most often.
The structural decision is rarely the actual problem. The problem is usually one of these six avoidable errors.

ES + 2 check digits + 4-digit bank code + 4-digit branch + 2 control digits + 10-digit account number — e.g. ES91 2100 0418 4502 0005 1332. The format is country-specific, but all SEPA IBANs (DE, FR, BE, LT, IE, etc.) are functionally equivalent for euro transfers and direct debits under SEPA rules ↗. Refusing a non-ES IBAN for direct debits is illegal but still happens.Banking is one decision. Structure, cover and tax are the next three. Make sure the rest of your Spanish business setup is in order too.
