Steps to Set Up a Company in Spain

Setting up a company in Spain is an exciting process, but it also requires planning, legal clarity, and a solid roadmap. Whether you want to open a shop, a service company, or an industrial business, understanding the steps is key to avoiding legal issues and starting off on the right foot. At Tecno Consultor, we not only help with the administrative part of starting your business—we also handle the adaptation and legal compliance of the premises where your business will operate. Everything starts long before you hang the “open” sign.

1. Choose the Right Legal Structure (SL, SA, SLU…)

The first step is to decide what type of company you want to form. In Spain, the most common are the Limited Liability Company (SL), the Public Limited Company (SA), and the New Enterprise Limited Company (SLNE). Each has its own features: the SL is ideal for small businesses and freelancers making the leap, due to its low minimum capital (€3,000) and flexibility; the SA is more suitable for larger businesses, requiring at least €60,000 in capital; the SLNE streamlines the process for individual entrepreneurs.

The legal form affects not only your capital requirements but also shareholder responsibilities, decision-making processes, and tax implications. For instance, an SL shields personal assets from business debts, unlike a sole proprietorship.

At Tecno Consultor, we always advise evaluating not just the business outlook, but also the type of activity. An industrial project requiring special permits or a shop that needs an operating license can benefit from a strong legal structure from the start.

2. Request a Company Name Certificate from the Central Commercial Registry

Every company needs a unique name. You’ll need to apply for a negative name certificate from the Central Commercial Registry. This document confirms that your desired name is not already in use. You can submit up to five name options in order of preference. The certificate is valid for six months and can usually be obtained online within 24–48 hours.

Choosing the right name isn’t just branding—it’s a legal requirement. We’ve seen entrepreneurs come in with logos and social media profiles, only to find out the name is taken. This step avoids such issues and allows you to move forward.

From our daily experience at Tecno Consultor, we’ve seen this step underestimated. We always recommend getting it done early, as you can’t sign the deed or open a business bank account without it.

3. Open a Bank Account and Deposit the Minimum Share Capital

Once you have your name certificate, you need to open a business bank account in the company’s name and deposit the minimum share capital (€3,000 for SL). The bank will issue a certificate confirming this deposit, which must be presented to the notary. Although it seems like a formality, it’s a vital step that officially kickstarts your company’s finances.

Many banks now offer this service online, but it’s still common to do it in person. Note: the deposited capital isn’t “locked”—after the company is registered, it can be used for initial purchases and operations.

At Tecno Consultor, we’ve witnessed the excitement of clients handing in their deposit slips. It’s the first tangible step, the moment when the business starts becoming real.

4. Draft the Company Bylaws and Define Legal Clauses

The bylaws are your company’s operational rulebook. They define your business activity, registered address, capital structure, management setup (sole director, joint, board), partner rights and duties, and decision-making processes.

They must comply with legal standards and be customized to your business. While templates exist, a tailored version is best. A too-narrow business scope could restrict future growth; too broad may raise tax concerns.

At Tecno Consultor, we often coordinate this with space adaptation. For example, if the business is in hospitality, the bylaws must mention “operation of hospitality establishments,” while we prepare the technical report for the premises license.

5. Sign the Public Deed of Incorporation Before a Notary

With your name certificate, bank deposit, and bylaws ready, it’s time to visit the notary. All founding shareholders must present the documents and sign the public deed of incorporation. The notary ensures everything is in order and that all parties understand their legal responsibilities.

The deed includes: the bylaws, shareholder IDs, capital details, appointment of directors, and any specific clauses (like transfer restrictions).

At Tecno Consultor, we accompany clients through this process. It’s common for last-minute questions to arise: what if a shareholder quits, how are statutes changed, etc. Clarity at this stage avoids future legal headaches.

6. Register the Company and Obtain a Permanent Tax ID (NIF)

After the notarial signing, the deed is submitted to the Commercial Registry of your province. This completes the legal registration and assigns a company number.

Simultaneously, apply for your permanent tax ID (NIF) from the Spanish Tax Agency. Initially, you get a temporary NIF valid for six months; once registered, it becomes permanent. Without it, you can’t legally issue invoices.

At Tecno Consultor, we handle this process so entrepreneurs don’t have to chase down multiple offices. Handing over that permanent NIF? That’s the moment we say, “You’re officially a business owner.”

7. Tax Registration and Form 036 Submission

Once registered, your company must file Form 036 with the Tax Agency, declaring its business activity, VAT status, retention policies, and business address. This step defines your company’s tax obligations.

Some businesses charge full VAT, others reduced, and some are VAT-exempt. You also disclose whether you’ll withhold income tax on payments to professionals or employees. Skipping this step delays invoicing capabilities.

At Tecno Consultor, we usually align this step with license applications. While handling the tax form, we also work on your technical dossier to keep everything on track for a faster opening.

8. Obtain a Digital Certificate and Register with Social Security (RETA)

In today’s digital Spain, a digital certificate is essential. It lets you submit taxes, receive notifications, sign documents, and manage admin tasks online. It’s issued by the FNMT and installed on your computer.

If shareholders will work in the company, they must register with Social Security, either under the self-employed scheme (RETA) or as company administrators. Each case has its own tax and contribution implications.

At Tecno Consultor, we help clients get their digital certificate while handling space and license compliance. This way, by the time your premises are ready, you’re also ready to do business online.

9. Use CIRCE and the Single Electronic Document (DUE)

Spain promotes the CIRCE platform (Information Center and Business Creation Network) and the Single Electronic Document (DUE) to simplify company incorporation. Some legal forms (especially SLNE) can complete most of the process online.

The DUE consolidates tax, social security, commercial registry, and other data into one form, reducing paperwork. However, some steps still require in-person visits.

At Tecno Consultor, we combine both approaches: we use CIRCE where possible and handle necessary physical processes like local licensing ourselves.

10. Additional Considerations and Common Mistakes When Starting a Company

Registration isn’t the final step. New companies often overlook bookkeeping legalizations, census declarations, business licenses, workplace safety plans, data protection policies, and more.

A common mistake is thinking that signing with the notary and opening a bank account is enough. In truth, launching a business includes adapting your premises to legal codes, securing sanitary licenses, installing safety equipment, etc.

That’s where Tecno Consultor brings the most value: beyond admin tasks, we handle the adaptation and legal compliance of your physical premises. We’ve seen launches delayed for months due to overlooked works or permits. When you call us early, we can develop the full technical project to ensure a smooth start.
