What You Need Before You Start (Key Decisions)
Before reserving a name or visiting the notary, the foundation of your project must be solid. Validating your business idea is step zero.
Once that’s done, you must make strategic decisions that will determine the future bureaucracy and tax implications. The most important are the legal structure, the definition of your business activity (for the IAE), and the capital you will contribute.
Legal Structure Options: Sole Proprietor, SL, or SA
Choosing the right structure is the first major milestone. It will determine your liability and your taxes. The three most common forms are:
1. Sole Proprietor (Autónomo)
This is the quickest and cheapest option to get started, ideal if you are an independent professional. There is no separation between your personal assets and the business’s, meaning you are responsible for debts with all your assets (unlimited liability). You have total control and minimal initial costs, but it is the riskiest option if the business grows.
2. Limited Liability Company (SL)
This is the star option for SMEs and the most popular in Spain. Your liability is limited to the capital contributed (if the company owes money, they cannot touch your personal assets). The legal minimum share capital for an SL is €1, although the recommended standard to convey solvency is still €3,000. It is the ideal structure if you have partners and want to protect yourself, as its management is much more flexible than an SA’s.
3. Corporation (SA)
Designed for large companies with extensive capital needs (a minimum of €60,000). It allows for the issuance of shares on the stock market and facilitates attracting major investors. Its management is much more rigid and costly, so it is not usually the recommended option for starting a standard business.
In this guide, we will focus on the process for an SL, as it is the most common question, although many steps are shared with the sole proprietorship.
Choosing the Name and Preliminary Checks
Your company’s name is your identity. You must differentiate between the legal name (the legal/tax name of your company, which must be unique) and the trade name (the brand your customers know you by).
Before falling in love with a name, you must verify that the legal name is available at the Central Mercantile Registry. Furthermore, it is vital to check that this name does not infringe on a prior trademark at the Spanish Patent and Trademark Office (OEPM) to avoid future legal problems.

Step-by-Step Procedures: The 8 Steps to Create Your SL
Once the key decisions are made, the process of how to set up a company begins. Although the bureaucracy may seem dense, it is actually a sequence of 8 logical and orderly steps.
Following this roadmap of the steps to create an SL (Limited Liability Company) is essential to avoid duplicating efforts or getting stuck on interdependent procedures. Below, we break down the exact order to go from an idea to having your definitive Tax ID (NIF).
Step 1: Register the Company Name (Certificate of Name Availability)
The very first thing is to ensure the name you want is available. This is done by requesting a “Certificate of Name Availability” (Certificado Negativo de Denominación Social) from the Central Mercantile Registry.
The fastest way is to do it online, for which you will need your digital business certificate (or a personal one). An expert tip: propose 5 different names to increase the probability of a first-try approval to 99%. You will receive the certificate in about 48 hours, which is valid for 3 months to sign before the notary.
Step 2: Open the Bank Account and Deposit the Share Capital
With the approved name certificate, it’s time to go to the bank. You will open an account in the name of the company “in formation” and deposit the share capital.
As we saw, although the legal minimum is €1, the recommended standard is €3,000 to project solvency (if you contribute less than €3,000, the partners are personally liable up to that amount). This money is not an expense; it is the first contribution to your company. The bank will issue you a certificate of this contribution, which is key for the notary.
Step 3: Draft the Bylaws (Estatutos Sociales)
The bylaws are the rules of the game for your company. They define the business purpose (what it does), the registered office, how decisions are made, the distribution of profits, etc.
Here is a tip that will save you money: do not be restrictive in your business purpose. Are you an electrician but might also do plumbing? Do you sell online but might also offer training? Include it all now. Adding activities at the beginning doesn’t cost more; doing it in the future means paying the notary and registry again.
Step 4: Sign the Public Deed of Incorporation Before a Notary
This is the business “I do.” With the name certificate, the bank certificate, and the drafted bylaws (often the notary’s office or your advisor will help you), you make an appointment.
The founding partners will sign the public deed of incorporation, the document that gives legal life to your company before a public notary.
Step 5: Apply for the Provisional Tax ID (NIF) from the Tax Agency
With the newly signed deed, the next immediate step is the Tax Agency (Hacienda). You must submit Form 036 (census registration) to request the company’s provisional Tax ID (NIF).
This number allows you to begin operating, open the definitive bank account, and issue invoices (albeit with certain limitations) while the final procedures are completed.
Step 6: Register the Company in the Mercantile Registry
Now, the deed must be registered in your province’s Mercantile Registry. Typically, the notary’s office handles this submission electronically.
This is the step that usually takes the longest in the process. The registry has up to 15 business days to review and register. Once registered, your company officially exists for all legal purposes.
Step 7: Final Registration with the Tax Agency and Social Security
With the company now registered (or in parallel with the provisional NIF), we return to the Tax Agency to communicate the definitive start of activity (using the same Form 036).
Simultaneously, the administrator (or administrators) must manage their registration for the IAE and Social Security, which is known as the “corporate partner” status (registration in RETA).
Step 8: Obtain the Definitive Tax ID (NIF)
Finally, once the Mercantile Registry registration is communicated to the Tax Agency, the Tax Agency automatically converts your provisional NIF into the definitive NIF.
And that’s it! At this point, your company is 100% operational to invoice, hire, and function completely normally.
Real Costs of Starting a Business (with examples)
Let’s talk money. The cost of starting a business in Spain varies greatly depending on whether you are a sole proprietor (almost free, beyond the monthly fee) or setting up an SL.
For a Limited Liability Company, although the law allows forming one with €1 of share capital, it is not recommended (due to the liability you assume up to €3,000).
Therefore, the recommended standard is still to contribute €3,000 (which is not an expense, it is the company’s money). To this, add the administrative costs (Notary, Mercantile Registry, name certificate), which usually range between €900 and €1,100, and can be higher in large cities. Don’t forget to set aside funds for fees and duties for any licenses your activity requires.
Legal Requirements After Registration (Your Obligations)
Registering the company is the starting pistol, not the finish line. From day one, you acquire ongoing obligations that you must manage to avoid penalties.
Tax and Accounting Obligations
Your company will have to file taxes. The main ones are the Corporate Tax (Impuesto de Sociedades), which taxes net profits (a general rate of 25%, or 15% for new companies in the first two years with profit), and VAT.
VAT (Value Added Tax) is a tax you collect from your customers (generally 21%) and which you settle quarterly with the Tax Agency, subtracting the VAT you have paid to your suppliers.
Social Security Contributions
Both the administrators (as corporate partners) and any employees you hire must be registered with Social Security. This involves a monthly payment of social security contributions, which finance the public pension and health system. It is a significant fixed cost that you must include in your financial planning.
Licenses, Openings, and Sector-Specific Regulations
It is not enough to be registered with the Tax Agency; your workplace must be legal. If you have a physical location (office, shop, workshop), you will need a business license (licencia de apertura) or, more commonly today, a responsible declaration (declaración responsable) to operate.
The dilemma between a responsible declaration vs. a license depends on the hazard or nuisance level of the activity (harmless vs. classified) and the size of the premises.
Classified activities (like hospitality or industry) require a technical project and are more costly. Do not forget other key cross-cutting regulations, such as Occupational Hazard Prevention (PRL) and strict compliance with GDPR (Data Protection), which is especially vital if you operate online.
Starting a Business in Spain as a Foreigner
Spain is a very attractive destination for international entrepreneurs, but if this is your case, you must add the immigration layer. These are the requirements for foreigners to start a business.
The first and essential thing is to obtain a Foreigner’s Identification Number (NIE). This is your tax identification number in Spain, and you will need it for absolutely everything (opening a bank account, signing at the notary, etc.).
Residency and Visa Requirements
To establish your business and reside legally in Spain, you will need an appropriate visa. The main options for entrepreneurs are:
Entrepreneur Visa: Designed for innovative projects of special economic interest to Spain. It requires a very solid business plan and a favorable evaluation from the authorities (ENISA). It facilitates residency and access to certain benefits.
Investor Visa (Golden Visa): Requires a significant investment (e.g., €2 million in public debt, €1 million in shares, or €500,000 in real estate). It offers advantages such as residency for the family and freedom of movement in the EU.
Self-Employment Work Visa: This is the more traditional path, where you demonstrate the viability of a more “normal” business (a shop, a consultancy) and the funds to support yourself.
Taking Advantage of Double Taxation Treaties
Spain has double taxation agreements with many countries. These treaties are key to avoiding paying taxes twice (in your home country and in Spain) on the same income. Make sure your tax advisor is familiar with these treaties to optimize your tax burden from day one.
Available Funding and Aid
Starting up requires capital, but not all of it has to come out of your pocket. There are numerous grants for entrepreneurs and financing options for entrepreneurs.
You can explore specific micro-loan lines for new businesses, which often have favorable conditions. There are also public financing lines (like those offered by ENISA) that support innovative projects. The key is to research which aid fits your sector and profile.
Common Mistakes That Delay or Increase the Cost of Registration
There are several mistakes when starting a company that can cost you time and money. One of the most serious is choosing the wrong legal structure, which can lead you to take on more risk than necessary.
Another common failure is defining a business purpose that is too narrow in the bylaws, which will force you to modify them (and pay) if you want to expand your activities.
Choosing the wrong IAE (Business Activity Tax) code can lead to problems with the Tax Agency. In partnerships, failing to properly define the administration structure (joint and several vs. joint) or not signing a shareholders’ agreement generates future conflicts.
Tools, Templates, and Checklists to Get Started
Organization is your best ally. Before you begin, lean on practical documents. Prepare a simple business plan template to clarify your model, market, and competitors.
Develop a detailed initial budget that includes not only the setup costs but also a forecast of fixed and variable expenses for the first 6-12 months (including separate columns for VAT and withholdings). Keep a basic tax calendar and a checklist of the documents you will need handy.
Frequently Asked Questions
We resolve the most common doubts that arise when starting this process. These are specific questions that complement the main information in the article and which you may not have considered.
Can I use the Share Capital money (the €3,000) for expenses?
Yes, and you should. That money (Step 2) is not a payment; it is a contribution. Once the company has its definitive Tax ID and the bank account is operational, that €3,000 is the company’s asset to pay for its first expenses: office rent, advisory fees, materials, or marketing. It is not money that is “locked.”
What happens if I start as a sole proprietor and later want to change to an SL?
This is a very common path. When your business as a sole proprietor grows, you invoice a lot (generally +€60,000/year), or you want to protect your personal assets, you can “transfer” your activity to an SL. The process is called a “contribution of a business branch” or, more simply, creating the new SL and starting to invoice from it, de-registering the sole proprietorship (or keeping it if you have multiple activities).
Do I need a business license if my business is 100% online and I work from home?
Generally, no. If your activity is professional (designer, programmer, consultant) and you carry it out in your primary residence without attending to the public and without employees, you usually do not need a municipal business license. You will only have to declare it when registering with the Tax Agency (Form 036), indicating that you use a portion of your home for the activity.
Is a shareholders’ agreement “pacto de socios” really necessary if there are only two of us?
It is not mandatory, but it is highly recommended. A shareholders’ agreement is like a prenuptial agreement: you don’t want to use it, but it is vital if things go wrong. It regulates what happens if a partner wants to leave, if they pass away, how their stake is valued, or how decision-making deadlocks are resolved. Signing it at the beginning, when everyone is in agreement, saves thousands of euros and problems in the future.
When does it make sense to create a Corporation (SA) instead of an SL?
An SA only makes sense in very specific scenarios. Primarily, if you plan to go public on the stock market, if you need to raise capital from investors in a very open way (by easily selling shares), or if your sector requires it by law (like some financial or insurance entities). For 99% of businesses, the SL is more flexible, cheaper, and easier to manage.
