Setting up a Sociedad Limitada (limited liability company) in Spain provides liability protection and tax benefits for growing businesses. This guide explains the step-by-step process, required documents, setup costs, and tax obligations for starting an SL.
An SL is the most common company structure for small business owners in Spain.
What is a Sociedad Limitada?
A Sociedad Limitada is a business structure where the partners have limited personal liability.
Your personal assets are protected if the business accumulates debts.
The company is taxed under corporate tax rules rather than individual income tax rules.
This structure is ideal if your business profits exceed €50,000 per year.
Minimum share capital
You need a minimum share capital of €3,000 to incorporate an SL.
This capital can be deposited in cash into a Spanish business bank account.
Alternatively, you can contribute assets of equivalent value, such as computers or office equipment.
Shareholder structure
An SL can be formed by a single person, known as a Sociedad Limitada Unipersonal.
There is no maximum limit to the number of partners or shareholders.
You must define the percentage of ownership for each partner in the bylaws.
Step-by-step incorporation process
Incorporating a company in Spain involves several official registry and notary steps.
The process usually takes between three and six weeks to complete.
Follow these chronological steps to register your business.
1. Request the name certificate
You must request a name certificate from the Registro Mercantil Central (Central Mercantile Registry).
This certificate is called the Certificado Negativo de Denominación Social.
It proves that your proposed company name is unique and not already registered.
You can submit up to five name options in order of preference.
The name certificate is valid for three months.
You must sign the notary deed before this certificate expires.
2. Deposit the share capital
Take your name certificate to a Spanish bank to open a business account.
Deposit the minimum capital of €3,000 into this new account.
The bank will issue a certificate proving the deposit, called a certificado bancario.
You will need to present this certificate to the notary later.
If you contribute physical assets instead of cash, you do not need this bank certificate.
However, you must provide a detailed list and valuation of those assets.
3. Draft the company bylaws
You must write the Estatutos Sociales (company bylaws) with your partners.
These bylaws define how the company operates, makes decisions, and distributes profits.
They must specify the company address, business activities, and administrator roles.
You should hire a gestor or lawyer to draft these bylaws.
Standard templates are available, but custom rules require professional review.
The bylaws must be approved by the notary during incorporation.
4. Sign the deed of incorporation
All shareholders must visit a notary to sign the deed of incorporation.
This deed is called the Escritura Pública de Constitución.
You must bring the name certificate, bank certificate, and your NIE or NIF.
If a shareholder cannot attend, they can grant a power of attorney.
The notary will charge fees based on the complexity of the bylaws.
The notary will send the signed deed to the regional tax authority.
5. Obtain a temporary NIF and register
You must apply for a temporary tax identification number, called the NIF provisional.
Submit Modelo 036 to the Spanish tax office to get this number.
This number allows you to register the deed at the Registro Mercantil (Mercantile Registry).
Registration at the Mercantile Registry makes the company a legal entity.
This registration step takes about two weeks.
Once registered, you can request your permanent NIF.
6. Register for economic activities
You must register the company for the economic activities tax, called the IAE.
You also need to register the company with the social security system.
Once registered, you can legally start issuing invoices to clients.

Questions and answers
Can a foreigner set up an SL in Spain?
Yes. You do not need to be a Spanish citizen or resident to own shares in an SL. However, you must obtain a Spanish NIE number. Any administrator of the company must also have a valid work permit or residency status.
What is the corporate tax rate for an SL?
The standard corporate tax rate is 25%. Newly created companies pay a reduced rate of 15% for the first two years of profit. This rate is often lower than the top personal income tax brackets.
Do I need to pay myself a salary from the SL?
Yes, if you work for the company. You can pay yourself a salary through a payroll system. Alternatively, you can distribute company profits as dividends to shareholders. Salary payments are deductible business expenses for the company.
Can I use my home address as the company headquarters?
Yes. You can register the company at your private rental address in Madrid. However, check your lease contract to ensure this does not violate your residential agreement. Many owners use a virtual office address instead.
What is a “socio administrador”?
The managing director. A socio administrador is a shareholder who also manages the daily operations of the company. This person has legal responsibility for company decisions. They must register as an autónomo colaborador under Spanish social security.
Can I convert my autónomo business into an SL later?
Yes. You can start as a sole trader and transfer your assets to an SL as your billing grows. This transfer requires auditing your assets and signing a new notary deed. It is a common path for growing freelancers in Spain.
Do I need a gestor to manage the company accounting?
Yes. Company accounting for an SL is much more complex than for a simple autónomo. You must file annual accounts, corporate tax returns, and quarterly VAT declarations. A professional accountant keeps your business compliant with tax laws.
