How you bank for business depends on your structure. As an autónomo (self-employed), you don't legally need a separate "business" account, but it's strongly advisable to separate business and personal money for bookkeeping, tax and your Renta/IVA filings — many autónomos use a dedicated personal-style account, and some banks offer autónomo accounts. For an SL (limited company), a company bank account is required as part of forming the company: you deposit the share capital into a new company account to obtain the bank certificate the notary needs to incorporate. To open business accounts you'll need NIE/identity, tax details (NIF/CIF), and the company's incorporation documents (for an SL), plus the usual source-of-funds checks. Choose a bank with good online/business tools, reasonable fees and autónomo/SME support. We open business accounts and form companies for expats end-to-end.
Autónomo vs Company
Your banking needs follow your business structure, so it's worth being clear which you are:
| Structure | Banking requirement |
|---|---|
| Autónomo (self-employed) | No legal requirement for a separate account, but strongly advisable to separate business money; some banks offer autónomo accounts. |
| SL (Sociedad Limitada) | A company bank account is required — used to deposit share capital during formation and to operate the company thereafter. |
The practical difference is significant. An autónomo is an individual, so banking is more flexible — you can run the business through a personal account, though separating business and personal funds is much better practice. An SL is a separate legal entity, which must have its own account, and opening one is actually woven into the company-formation process (you can't fully incorporate without it). So if you're deciding between trading as an autónomo or forming an SL (a choice covered in our autónomo vs SL comparison), the banking implications are part of the picture. Either way, getting the right account set up correctly is an early, essential step in operating a business in Spain, and one we handle alongside the wider setup.
Autónomo Banking
As an autónomo, you're operating as an individual, so legally you can receive income and pay expenses through a personal account. However, the strong recommendation is to keep a dedicated account for your business activity, separate from your personal spending, for several reasons: it makes your bookkeeping and accountant's job far easier, it cleanly supports your quarterly and annual tax filings (IVA/VAT and income tax), and it gives a clear record if the tax authority ever queries your figures.
Some Spanish banks offer specific autónomo accounts with features aimed at the self-employed (invoicing tools, tax-payment direct debits, sometimes fee structures geared to small business), while others simply use a standard account designated for business use. The right choice depends on your activity level and what tools help you — a high-volume autónomo benefits more from business features than a low-volume one. The key principles are separation (don't mix business and personal) and choosing an account with reasonable fees and good online tools, since you'll be making regular tax payments and managing cashflow through it. We help autónomos set up appropriately, in conjunction with their registration and accounting.
SL Company Accounts
An SL (Sociedad Limitada — the standard Spanish limited company) is a separate legal person and must have its own bank account, in the company's name, distinct from the directors' or shareholders' personal accounts. This isn't just good practice — it's a legal and practical necessity: the company's income, expenses, payroll, taxes and dealings all run through it, and mixing company and personal money undermines the limited-liability separation and creates tax and accounting problems.
Crucially, the company account is part of how the company comes into existence (see the formation link below): you open an account in the (forming) company's name and deposit the share capital, the bank issues a certificate confirming the deposit, and that certificate is required for the notary to incorporate the company. After incorporation, the account becomes the company's operating account. Because the bank, the notary and the company registry steps interlock, opening an SL account is best handled as part of a managed formation process rather than piecemeal — which is exactly how we set up companies for expat clients, coordinating the banking with the legal incorporation so the sequence runs smoothly.
An SL must have its own account — and it's part of forming the company
A Sociedad Limitada is a separate legal entity that must bank in its own name. Opening the account is built into incorporation: you deposit the share capital, the bank certifies it, and the certificate is needed for the notary to form the company. Keep company and personal money strictly separate thereafter.
The Formation Link
For an SL, opening the bank account is one step in a defined incorporation sequence:
Reserve the company name
Obtain the name-availability certification from the central commercial registry.
Open the (forming) company's bank account
Open an account in the company-in-formation's name to receive the share capital.
Deposit the share capital & get the certificate
Pay in the share capital; the bank issues a certificate of deposit that the notary requires.
Incorporate at the notary
Sign the deed of incorporation before a notary, presenting the name certification and bank certificate.
Register & obtain the CIF
Register the company at the commercial registry and obtain its tax number (CIF/NIF); the account becomes the company's operating account.
The point is that the bank account isn't a separate errand — it's embedded in the formation, and the steps must happen in the right order (you need the name certification before the account, the capital deposit before the notary, etc.). Getting the sequence and the documents right is what makes incorporation smooth; getting it wrong causes delays. This is why forming an SL is best done as a coordinated process covering the legal, banking and tax steps together — our company-formation service for expats handles the whole chain, including opening the company account and obtaining the capital-deposit certificate, so the company is properly and promptly incorporated.
Documents Needed
Requirements depend on the structure, but expect to provide:
- For an autónomo: your passport and NIE, your tax registration as autónomo (alta), and proof of your activity/income; source-of-funds information as usual.
- For an SL (at formation): the directors'/shareholders' identity and NIE, the name-availability certificate, the draft incorporation details, and the share capital to deposit; after incorporation, the deed and the company's CIF.
- Both: the bank's own forms and anti-money-laundering / source-of-funds checks, which can be more involved for business accounts.
Business accounts generally face stricter due diligence than personal accounts — banks want to understand the business, its owners, its activity and the source of its funds — so being organised with the documentation smooths the process. For an SL especially, the documents tie into the formation steps, so they need to be produced in the right sequence. Foreign documents may need translation. We prepare and coordinate all of this for expat clients, so the account opening (and, for a company, the incorporation) proceeds without missing pieces or wrong-order hold-ups.
Costs & Choosing a Bank
Business accounts typically cost more than personal accounts — higher maintenance fees, transaction charges, and charges for business services — though, as with personal accounts, the exact figures vary by bank and change over time, and some conditions can reduce them. Because a business runs many transactions and tax payments through the account, the fee structure and the quality of the online/business tools matter more than for a personal account, and are worth weighing carefully.
When choosing a bank for business, prioritise: reasonable business fees, good online banking and invoicing/accounting integrations, support for tax-payment direct debits (you'll be paying IVA and other taxes regularly), autónomo/SME-friendly products, and — for many expats — English-language business support. The same choosing-a-bank principles apply, weighted toward business functionality. We don't quote bank fees (banks set their own) but we factor them into the bank we recommend, and we quote clearly for our own account-opening and formation services. Getting the right business account from the start — properly separated, with good tools and sensible fees — saves friction as the business grows.
How We Help
We set up business banking for expats end-to-end. For autónomos, we help register and open an appropriate, well-separated account with good tools and fees. For SL companies, we run the whole formation — name certificate, opening the company account, depositing the share capital and obtaining the certificate, incorporating at the notary, and registering and obtaining the CIF — coordinating the banking, legal and tax steps. We handle the NIE, documents, translations and source-of-funds side too. It's part of our business & corporate support, in English on a clear quote.

Frequently Asked Questions
Not legally — as an autónomo you're operating as an individual, so you can receive income and pay expenses through a personal account. But it's strongly advisable to keep a dedicated account separate from your personal spending: it makes bookkeeping and your accountant's job far easier, cleanly supports your quarterly and annual tax filings (IVA and income tax), and gives a clear record if the tax authority queries your figures. Some banks offer specific autónomo accounts with useful tools. The key principles are separation and choosing reasonable fees and good online tools.
Yes — an SL (Sociedad Limitada) is a separate legal entity that must have its own account in the company's name, distinct from the owners' personal accounts. It's both a legal and practical necessity: the company's income, expenses, payroll and taxes run through it, and mixing company and personal money undermines limited liability and creates tax and accounting problems. The account is also part of how the company is formed — you deposit the share capital and obtain a bank certificate the notary needs to incorporate. We open SL accounts as part of company formation.
For an SL, opening the account is a step in incorporation. After reserving the company name, you open an account in the company-in-formation's name and deposit the share capital; the bank issues a certificate of deposit, which the notary requires to sign the deed of incorporation. The company is then registered and obtains its tax number (CIF), and the account becomes its operating account. The steps must happen in the right order, which is why forming an SL is best done as a coordinated process covering legal, banking and tax steps together — as we do for clients.
For an autónomo: your passport and NIE, your tax registration as autónomo, and proof of activity/income, plus source-of-funds information. For an SL at formation: the directors'/shareholders' identity and NIE, the name-availability certificate, the draft incorporation details and the share capital to deposit; after incorporation, the deed and the company's CIF. Both face the bank's anti-money-laundering checks, which are often more involved for business accounts. Foreign documents may need sworn translation. We prepare and coordinate all of this so opening (and, for a company, incorporation) proceeds smoothly.
Generally yes — business accounts typically have higher maintenance fees, transaction charges and charges for business services than personal accounts, though figures vary by bank and some conditions can reduce them. Because a business runs many transactions and tax payments through the account, the fee structure and the quality of the online/business tools matter more than for a personal account. Prioritise reasonable business fees, good online banking, support for tax-payment direct debits and autónomo/SME-friendly products. We factor fees into the bank we recommend.
As with personal banking, there's no single best — it depends on your needs. For business, prioritise reasonable business fees, good online banking and invoicing/accounting integrations, support for tax-payment direct debits (you'll pay IVA and other taxes regularly), autónomo/SME-friendly products, and, for many expats, English-language business support. The same choosing-a-bank principles apply, weighted toward business functionality. We assess your business and recommend and open the right account, coordinating with company formation for an SL. Book a consultation to arrange it.
Foreigners can open Spanish business accounts — you'll need an NIE and the relevant documents, and for an SL the formation steps must be completed. Some elements can be handled remotely or via a representative with power of attorney, which is often how expat clients form a Spanish company without being present for every step, though banks' due-diligence requirements and in-person needs vary. We frequently set up Spanish businesses and their banking for expats, using powers of attorney where helpful, so the company and account can be established efficiently. Book a consultation to discuss your situation.
Yes — strongly. For an SL it's essential (mixing company and personal money undermines limited liability and causes tax/accounting problems). For an autónomo it's not legally required but is strongly advisable: separation makes bookkeeping and tax filings far cleaner and gives a clear record if the tax authority queries your figures. Running business income and expenses through a dedicated account, distinct from personal spending, is good practice for any business structure and pays off at tax time. We help set accounts up with proper separation from the start.
