How to start a business in Spain in 2027: registration, costs and choosing a legal structure

You can set up a company in Spain with capital of 1 euro, while a significant part of the registration process can be completed electronically. However, the low formal entry threshold can create a somewhat misleading impression of simplicity. Under the current rules, the minimum capital for a limited liability company is 1 euro, but until the capital together with the mandatory reserve reaches 3000 euros, at least 20% of profits must be allocated to that reserve. This requirement is established by Spain's Law 18/2022 on business creation and growth.

Digitalisation has noticeably accelerated the process of starting a business in Spain. The government electronic company formation system allows several registration procedures to be combined into a single process. The latest published government data shows the scale of the effect: among limited liability companies incorporated under standard articles through this system, 66,4% completed the procedure in less than one day, while another 22,34% were completed within one to five days. The speed of an individual registration still depends on the documents, the notary, the registry and the specific features of the company.

For an entrepreneur, the practical question goes well beyond “where do I file the application?”. You need to choose between operating as a sole trader and forming a company, determine the tax regime, check a foreign national's right to work, obtain a foreigner identification number, calculate social security contributions and understand the municipality's requirements. A mistake at this stage can affect taxes and the owner's personal liability for years to come.

Below, we explain how to start a business in Spain in 2027 from an entrepreneur's perspective: from testing the idea and choosing the legal structure to registration, financing, premises and permits. Any rules that may change by the actual registration date in 2027 should be checked again immediately before filing the documents.

Before registration: four things to check on paper

A good idea is not yet a working business model. Before spending money on a notary, premises and equipment, an entrepreneur is better off answering several uncomfortably specific questions: who will pay, how many such customers exist, why they will choose the new business and what level of sales will cover fixed costs. Spain's registration system can create a legal entity fairly quickly, but it cannot create demand.

The budget for the first few months deserves particular attention. Rent, insurance, accounting support, social security contributions, equipment, wages and taxes can completely change the appeal of a project that looked excellent in the original spreadsheet. For a café, shop or workshop, renovation and municipal requirements must also be added, while a consultant or programmer may be able to start with a much lighter cost structure.

A foreign owner also has to account for another resource: the ability to work with the Spanish administrative system.

Fluent Spanish makes everyday life much easier, but not speaking it does not close the door to entrepreneurship. It is far more useful to arrange professional support in advance for matters involving contracts, taxes, employment law and permits.

Preparation serves a very measurable purpose here. The more accurately the project's economics are calculated before registration, the easier it becomes to determine whether a company is needed, how much money should remain in reserve and when the business is genuinely ready to begin operating.

Sole trader or limited liability company

Spain offers several legal business structures, but for a small new business the choice often comes down to two models: operating as a sole trader or forming a limited liability company. The first is usually simpler at the outset, while the second creates a separate legal entity and suits many projects involving partners, employees or significant commercial risks.

A sole trader in Spain operates in their own name. No separate company is incorporated for this purpose, so the initial administrative burden is lower. This format is often used by consultants, tradespeople, creative professionals, developers and owners of small service businesses.

A limited liability company is a separate legal entity. It has its own name, capital, articles of association, tax number, accounting obligations and established management structure. In normal circumstances, the liability of shareholders is linked to their contribution, although legislation provides for exceptions and additional obligations.

The difference becomes especially clear in practical terms.

For this reason, business structures in Spain are better compared according to the future operating model rather than registration costs alone. Saving a few hundred euros at launch offers little benefit if, six months later, the structure has to be reorganised because of an investor, a partner or a new level of liability.

A company with 1 euro of capital: an attractive figure with an important condition

The reform of capital requirements has been one of the most noticeable changes in Spanish corporate law in recent years. Incorporating a limited liability company no longer requires the previous minimum capital of 3000 euros.

The law allows a company to start with 1 euro.

However, a limited liability company in Spain with capital below 3000 euros operates under an additional creditor protection mechanism. At least 20% of the profit earned must be allocated to a mandatory reserve until the combined amount of capital and that reserve reaches 3000 euros. If the company is liquidated and its assets are insufficient to meet its obligations, the shareholders are jointly liable up to the difference between 3000 euros and the subscribed capital.

Symbolic capital should therefore not be treated as a recommended business budget. A shop will need inventory, a restaurant will need equipment and working capital, while a service company will need funds for salaries and software. The statutory minimum only answers the question of the amount from which a company may legally be incorporated.

The cost of the fast-track procedure is also worth considering. Current government guidance for companies using standard articles of association and capital of no more than 3100 euros lists notary fees of 60 euros and Commercial Registry fees of 40 euros plus value added tax when the incorporation is completed through the government electronic system. Additional services and the circumstances of a particular registration may increase the final amount.

Six stages of opening a company without bureaucratic confusion

It is easier to view registration as a sequence of decisions. The name and legal form define the future structure of the business, the financial plan shows whether it is viable, while premises and permits connect the project with a specific municipality.

In a basic scenario, registering a business in Spain includes the following stages.

1. Choose a trading name and check whether it can be used.
2. Select the legal structure taking into account taxes, liability and future growth plans.
3. Prepare a business plan and financial model for at least the first year of operations.
4. Determine sources of start-up and working capital financing.
5. Find premises if the activity cannot be carried out remotely or from home.
6. Check municipal, regional and sector-specific permits before starting operations.

The sequence of individual procedures varies depending on the type of business. Incorporating a company requires steps that a standard sole trader does not have to complete, while opening a restaurant is not comparable in terms of permits to working as a translator from a home office.

A general guide is therefore useful as a map, but the activity determines the final route. Particular care is needed in sectors connected with food, construction, transport, healthcare services and other regulated activities.

Company name: the first check before the notary

A trading name can become a valuable asset long before the business reaches significant turnover. At the same time, the name used to present the business to customers and the official name of the legal entity may serve different purposes.

A company must obtain confirmation that the chosen name is available from the Central Commercial Registry. This document forms part of the standard set required to incorporate a legal entity. It is better to complete the check before ordering signs, packaging and brand materials.

Brand protection is a separate matter. Registering a company with the state and obtaining legal protection for a trademark serve different purposes. A project planning to build a recognisable brand should therefore treat these as separate steps.

A good name needs to work both legally and commercially. An attractive brand offers little value if it cannot be registered or safely used in the chosen category of goods and services.

What is required to create a limited liability company

Company formation involves several institutions. It will usually require confirmation of the company name, bank or other documents relating to capital depending on how the contribution is made, incorporation documents, a notarial deed, a tax number and subsequent entry in the Commercial Registry.

A limited liability company can be registered through the government electronic company formation system. This uses a single electronic document that transfers information between the participating authorities. Standard articles of association reduce the number of individual decisions and can significantly speed up the process.

In practical terms, the sequence looks like this: the founders determine the company structure and capital, obtain confirmation of the name, prepare the required information, sign the incorporation document before a notary, complete tax identification and finalise registration of the company in the Commercial Registry. The exact set of steps depends on the composition of the shareholders and the chosen method of incorporation.

If the business has an unusual structure, standard speed stops being the main criterion. Tailored provisions in the articles of association can regulate managers' powers, relationships between partners, transfers of shares and decision-making. For a project with several owners, well-drafted articles can be far more valuable than saving a few days.

How to register as a sole trader

For individual business activity, the procedure is shorter. The entrepreneur needs to complete tax registration and register with the social security system. Since February 2025, the former simplified tax form 037 is no longer used, so tax registration is completed through form 036.

The second major part of registering as a sole trader concerns the special social security regime for self-employed workers. The social security administration allows registration through the Importass electronic service. In official guidance published in June 2026, the procedure is described as a sequence of six electronic steps.

Before registering with the social security system, the entrepreneur must register the economic activity with the tax authority. The filing specifies the start date of the activity, which also becomes the date from which social security contributions begin to accrue.

It is particularly risky to start issuing invoices first and only remember registration afterwards. It is better to define the actual start date of commercial activity in advance and coordinate the tax and social security procedures.

A business plan for Spain should answer uncomfortable questions

A business plan is useful not only for a bank or investor. For the owner, it is a way to test the idea in financial terms. How many customers need to be acquired each month? What gross margin remains after direct costs? What happens if sales turn out to be one third lower than expected?

A business plan in Spain is particularly relevant when raising finance or applying for certain immigration permits for entrepreneurs. The document should set out the product, market, competition, financial model, investment, expected employment and the viability of the business.

If capital is going to be raised within the country, it is practical to have a full Spanish version of the document. An international project may also need an English version, but working documentation for Spanish organisations should meet their requirements.

The weak point in many plans is not the revenue forecast but the costs. Taxes, social security payments, rent, insurance, licences, renovation and a liquidity buffer can significantly increase the amount required before the business reaches a stable cash flow.

Where to get funding for your launch

Spain offers entrepreneurs several financing options, and there is no need to choose just one in advance. Personal savings can be combined with a bank loan, a government programme or private capital.

Business financing in Spain is usually built around several sources.

• Personal capital allows you to retain full control of the project and avoid taking on debt during the first few months.
• A bank loan suits a business that can demonstrate its ability to repay and meet the lender's collateral requirements.
• A credit line creates a liquidity reserve for day-to-day expenses and unexpected cash-flow gaps.
• Government support may be available to certain types of businesses, sectors, regions and investment projects.
• A private investor can provide capital in exchange for equity, future returns or other agreed terms.

The cost of money matters just as much as its availability. A loan with an inconvenient repayment schedule can create problems even for a profitable business if customer payments are unevenly distributed throughout the year.

A financial reserve at launch therefore acts as protection against an overly optimistic scenario. The higher the project's fixed costs, the more important it is to have a buffer for the period when sales are still gaining momentum.

Premises: check permits before choosing the perfect address

Renting commercial premises seems straightforward until the intended use of the property comes into question. Being able to rent a space does not automatically mean that you will be allowed to operate a particular business there.

Before signing a long-term lease, you need to check the permitted activity, the technical condition of the property, accessibility requirements, ventilation, fire safety, noise restrictions and any planned construction work. Commercial premises in Spain may require additional investment that is not obvious during the first viewing.

Requirements are determined by the municipality and the nature of the activity. A clothing shop, bakery, workshop and consultant's office will face different technical conditions. Even two similar-looking premises on neighbouring streets may have a different history of permits and approvals.

The opening date should therefore appear in the business plan only after the premises have been checked. Paying several weeks of rent without being able to operate can easily become one of the most frustrating items in the start-up budget.

Licences and responsible declaration

Municipalities play a significant role in opening an offline business in Spain. Requirements depend on the city, autonomous community, size of the premises, type of work involved and the potential impact of the activity on the surrounding area.

For some types of activity, a responsible declaration is used instead of a traditional prior licence.The entrepreneur declares that the premises and the activity comply with the applicable requirements and, where permitted, can begin operating without waiting for a lengthy approval procedure. The municipality retains the right to carry out a subsequent inspection.

More complex, potentially hazardous or regulated businesses go through additional procedures. A restaurant with a kitchen, an industrial workshop and a small administrative office should therefore not plan their openings according to the same timetable.

The most practical strategy is simple: check the municipality's requirements before signing a lease and starting renovation work. This makes it possible to compare the proposed address with the real cost of launching the business.

Taxes: how much you will have to pay after registration

Registration is completed relatively quickly, but tax obligations remain with the business continuously. For a sole trader, personal income tax plays the main role, while companies are subject to corporate taxation. Value added tax also applies unless the activity falls under an exemption or a special regime.

The standard rate of value added tax in Spain is 21%, while reduced rates apply to certain goods and services. However, tax included in the sale price cannot automatically be treated as a business expense equal to the full amount charged: businesses account for input and output tax according to the applicable rules.

For a sole trader, social security contributions are added to taxes. These contributions need to be included in the financial model before setting service prices, because an hourly rate that looks attractive to clients may still make the business unprofitable for the owner.

A company will require fuller accounting records, annual reporting and compliance with corporate obligations. Comparing the two structures solely by the percentage rate of a single tax is therefore misleading.

What may change by 2027

Planning a launch for 2027 requires caution: at the time this material was prepared, the future tax year had not yet begun, so projected changes should not be presented as rules already in force. The basic rules for incorporating a limited liability company, including minimum capital from one euro, are established in current legislation, while the official electronic registration system continues to be used to simplify company formation.

An entrepreneur planning to open in 2027 should check tax rates, social security contribution amounts, electronic invoicing rules and regional support programmes again immediately before registration. The tax calendar and social security arrangements for sole traders are especially sensitive to updates.

There is also a more practical reason not to prepare documents six months in advance using an old checklist. Spanish public administration is actively moving business interactions into digital channels, so forms, submission routes and technical requirements continue to change. A procedure described in a two-year-old guide may lead to the same result, but through a different process.

For a business in Spain in 2027, it is more useful to follow the rule in force on the actual filing date than an attractive guide promising that nothing will change. Legal accuracy here can translate directly into money.

What to check one week before registration

Most unpleasant surprises arise not from complex legislation but from one overlooked condition. The owner chooses the wrong tax regime, fails to check whether the activity is permitted, signs a lease before reviewing municipal requirements or budgets only for the cost of incorporating the company.

Before launch, it is worth comparing the legal structure once again with the actual business model. If the business starts with one specialist and modest turnover, operating as a sole trader may be more rational than forming a company. If partners, significant liabilities, employees and investment are involved, a corporate structure has stronger arguments in its favour.

The lease agreement, permits, tax registration, social security, banking arrangements and accounting process also require separate checks. Each of these points seems secondary only until it prevents the business from starting.

Good preparation does not remove all business risk. It allows the owner to spend more energy on customers and the product instead of correcting administrative decisions made in a hurry.

From registration to an operating business

Setting up a business in Spain has become technically much easier than its bureaucratic reputation might suggest. The state allows a limited liability company to be formed with minimum capital from one euro and provides for electronic registration through a centralised system. The official text of Law 18/2022 also requires founders to be informed about the advantages of electronic incorporation, including costs, timeframes and the possibility of completing related tax and social security procedures.

However, a legally registered company and a viable business remain two different outcomes. For a future owner, calculating taxes, social security payments, rent, working capital and customer acquisition costs matters more than saving a few days on paperwork.

For a project launching in 2027, the final check of the rules should be carried out immediately before filing the documents. According to the official Spanish Official State Gazette, the current rule keeps the minimum capital for a limited liability company at one euro and maintains special requirements until the combined amount of capital and reserves reaches 3000 euros. Any new rules adopted after this material is published should be taken into account as of the actual registration date.

Once the business structure, budget and required permits have been determined, Flagma can be useful at the next practical stage: finding commercial offers, equipment, transport, business services, employees and other resources without which a registered company cannot become an operating business.
