Business Services in Spain: Formation, Tax and Payroll

Who Needs Business Help in Spain

Businesses come here at different stages: before an entity exists, when trading and filing begin, when corporate records or contracts need attention, and when the first employee or Spanish operation creates new obligations.

Five common jobs often run in sequence for the same business. Each lands on a different service or section:

• Forming a company. Choosing between trading as autonomo and forming an SL, then registering whichever structure fits.
• Keeping the accounts. Running bookkeeping, periodic filings, corporate tax and annual accounts on their respective deadlines.
• Registering for VAT. Getting an IVA number so the business can trade and invoice legally, then keeping the filing calendar that follows.
• Managing the company. Keeping shareholder and board records, registry filings and commercial legal work current after incorporation.
• Hiring staff. Registering the company and each employee with Social Security, then running payroll on a monthly cycle.

The same business may also need a corporate bank account, employment advice or foreign-investment support as it moves through that sequence. Those related services are linked below.

Setting Up a Company in Spain

The first decision is the structure: trade as autonomo, a self-employed registration with unlimited personal liability, or form an SL (sociedad limitada), a limited-liability company that separates business debt from personal assets. Autonomo vs SL covers which fits which situation; autonomo suits a lighter-weight solo operation, and an SL suits a business taking on real liability or outside investment.

Forming an SL runs through a fixed sequence. A name certificate from the Registro Mercantil Central confirms the chosen company name is not already taken, the founders then sign the incorporation deed (escritura) before a notary, with a minimum share capital of 1 euro under Article 4 of the Ley de Sociedades de Capital as amended in 2022, and the notary files the deed with the Registro Mercantil to bring the company into existence. Company formation in Spain names every step in order. Once a company exists, anyone can check its record on the register directly; looking up a company on the register covers how.

A foreign-owned SL also needs a corporate bank account once formed, a separate application from a personal one; bank accounts in Spain covers what that account needs.

Accounting, VAT and Corporate Tax in Spain

Once trading starts, bookkeeping, tax filings and company accounts run on separate calendars. Accounting services in Spain cover the books, periodic filings and annual accounts. Every trading business also needs a NIF, its Spanish tax identification number, and registers that NIF for VAT (IVA) before it starts invoicing; the VAT number in Spain is the same NIF with an ES prefix. VAT registration in Spain covers the service, while the VAT guide covers the mechanics and current rates.

The rates, forms and filing deadlines for company tax stay together in the corporate tax guide. A company that needs the return prepared can use the accounting service, keeping the explanation and the filing work in their proper places.

Corporate Legal, Secretarial and Ongoing Compliance in Spain

Incorporation is not the end of the company-law work. An SL may need shareholder and board resolutions prepared, minute-books and ownership records kept current, changes filed at the Registro Mercantil, commercial contracts reviewed, and annual accounts approved through the correct corporate process. Foreign groups may also need a Spanish branch registered or a separate NIF for the foreign parent.

This work is handled as part of the wider business service where it overlaps with formation, accounting and tax. Company formation in Spain covers incorporation, branch registration and the first corporate records; accountants in Spain covers annual accounts and recurring filings. For a contract, shareholder, governance or company-secretarial matter, describe the issue in the enquiry form so the commercial legal work can be scoped separately.

Doing business in Spain covers the wider operating and compliance picture before a business commits to a structure.

Hiring Staff and Investing in Spain

Hiring starts with registration, and which one depends on who is working. A founder trading as autonomo registers under RETA; hiring an employee registers that person under the Regimen General, on a contract Spanish employment law governs, with the company first registered as an employer with the Tesoreria General de la Seguridad Social. Payroll then runs monthly: gross-to-net calculation, withholding, and the Modelo 111 and Modelo 190 filings to the Agencia Tributaria. Payroll services in Spain covers registration and the filing calendar in full.

Some businesses hire through an Employer of Record without setting up their own entity, which raises a legal question: an EOR arrangement carries cesion ilegal exposure, illegal worker supply, under Article 43 of the Estatuto de los Trabajadores, when the client company, not the EOR, holds day-to-day control. Payroll services in Spain covers what keeps an arrangement on the right side of that line.

A company set up with non-Spanish capital raises a further question: transfer-pricing rules and Spain’s foreign-investment reporting obligations both apply. Investing in Spain names both and where they bind.
