Entering the Spanish market can be a great opportunity for a foreign company: access to European customers, skilled talent, infrastructure, ports, airports, industrial suppliers, technology hubs, and a strategic position for operating in Southern Europe. But it can also become a source of problems if the entry is improvised.
Many international companies begin with the commercial side: they find distributors, sign contracts, hire a local salesperson, or open a representative office. The problem arises when this activity generates unforeseen tax, labor, accounting, or commercial obligations. In Spain, entering the market incorrectly is often costly: improper tax registrations, risks of establishing a permanent establishment, incorrect VAT application, deficient employment contracts, problems with Social Security, bank delays, or inefficient corporate structures.
At MGI Àmbit, a law and economics firm in Barcelona, we help foreign companies establish themselves in Spain with a comprehensive approach: international taxation, corporate structure, accounting, payroll, labor compliance, and operational planning. In this guide, we analyze the most common mistakes foreign companies make when entering the Spanish market and how to avoid them before they lead to penalties, costs, or restrictions.
Quick summary
- Objective of the article: to identify the most common mistakes made by foreign companies when starting operations in Spain.
- Target profile: foreign parent companies, international groups, startups, industrial companies, e-commerce, service firms and companies that want to open a market in Spain.
- Key errors: choosing the wrong entry structure, ignoring the risk of permanent establishment, misapplying VAT, hiring without labor planning, and not preparing local accounts.
- Main risk: starting commercial operations before having properly defined the taxation, legal form and administrative obligations.
- Solution: conduct a preliminary diagnosis for entering the Spanish market with coordinated tax, labor, accounting and commercial advice.
Why foreign companies make mistakes when entering Spain
Most errors don't occur due to a lack of interest in complying with the law. They occur because companies apply the same logic in Spain as they do in their home country. However, each market has its own rules: tax obligations, administrative deadlines, labor formalities, tax agency criteria, commercial registries, collective bargaining agreements, and accounting documentation.
A foreign company may have a perfectly valid business model in its home country and still create problems in Spain if it doesn't adapt its structure. For example, selling from the parent company without analyzing whether there is a stable presence can create a permanent establishment risk. Hiring a Spanish professional as a freelancer when they actually work as an employee can lead to labor issues. Using international contracts without local review can result in ineffective or conflicting clauses.
Therefore, entering the Spanish market should not be treated as a simple administrative procedure. It should be approached as an implementation project that combines taxation, commercial law, labor law, accounting, treasury, banking, invoicing, and reporting.
Error 1: Not defining the entry structure before starting to sell
The first mistake is entering the Spanish market without deciding on the legal and tax structure that will support that activity. Some companies start with a local salesperson, an agency agreement, a logistics warehouse, or agreements with Spanish clients without analyzing whether this presence requires registration, opening a branch, establishing a subsidiary, or declaring a permanent establishment.
The entry structure must be decided before signing any relevant contracts. Selling from abroad is not the same as operating through a Spanish subsidiary. Similarly, opening a branch is not the same as operating through an independent distributor. Each approach alters the level of control, responsibility, taxation, accounting obligations, and management costs.
| Input formula |
When might it fit? |
Risk if you choose wrong |
| Direct sales from abroad |
Limited operations, with no office, employees, or stable presence in Spain. |
Misapplication of VAT, logistics, guarantees, contracts or indirect taxation. |
| Local distributor |
The company wants to sell in Spain without its own structure and with an independent business partner. |
Losing control over brand, prices, customers, or service quality. |
| Sales Agent |
The company wants to attract customers with local support, but without initially creating a Spanish company. |
Tax risk if the agent has powers or acts in a dependent manner. |
| Branch |
Stable activity in Spain without creating a legally separate company from the parent company. |
Direct responsibility of the parent company and specific registration and accounting obligations. |
| Spanish subsidiary |
Stable project, local hiring, Spanish invoicing and long-term growth strategy. |
Higher initial cost, but greater operational and tax clarity. |
| Permanent establishment |
There is ongoing activity in Spain without having established a local company. |
Risk of regularization if the company does not recognize it or pay taxes correctly. |

Error 2: Ignoring the risk of permanent establishment
Establishing a permanent establishment is one of the most sensitive issues for a foreign company. Many companies believe that as long as they don't create a Spanish subsidiary, they have no relevant tax obligations in Spain. This idea is dangerous.
A permanent establishment may exist when a non-resident company carries out business activities in Spain through facilities, workplaces, offices, warehouses, management centers, or agents acting with the authority to enter into contracts on a regular basis. In practice, the risk arises when the company has a stable local presence, even if it formally continues to invoice from its foreign parent company.
The mistake lies not only in failing to declare it. It also lies in not properly documenting which income and expenses correspond to the Spanish business, not maintaining separate accounts, or not correctly applying the rules for related-party transactions between the head office and the business in Spain.
Warning signs of possible permanent establishment
- The company has an office, premises, warehouse or stable sales team in Spain.
- There are staff in Spain who negotiate or close contracts on behalf of the parent company.
- The service is provided continuously from Spanish territory.
- There is an effective management or operational decision-making center in Spain.
- Material or human resources are routinely used in Spain to generate income.
- The parent company invoices from abroad, but the real economic activity takes place wholly or partially in Spain.
The solution is not to hide the operations, but to structure them correctly. In some cases, adjusting contracts and roles will suffice. In others, it will be necessary to declare a permanent establishment, open a branch, or create a subsidiary.
Error 3: Processing the NIF, form 036 and tax registrations late
Another very common mistake is thinking that a company can start operating and regularize its operations later. In Spain, certain registrations must be correctly completed before starting business, issuing invoices, hiring employees, importing goods, or withholding taxes.
The census declaration using form 036 is a key document because it provides the Tax Agency with essential information: identification, business activity, VAT obligations, withholdings, tax domicile, representatives, premises, tax regimes, and other relevant circumstances. An incorrectly checked box can lead to erroneous obligations or omit declarations that the Tax Agency may later request.
| Procedure |
What is it for? |
Common mistake |
| Tax Identification Number (NIF) of a foreign or Spanish entity |
Tax identification with the Tax Agency. |
Requesting it late can delay contracts, banking, billing, or records. |
| Model 036 |
Registration, modification or deregistration in the census of entrepreneurs, professionals and withholding agents. |
Incorrectly marking VAT obligations, withholdings, or economic activity. |
| ROI / VIES |
Intra-community operations where applicable. |
Issuing or receiving intra-community invoices without properly validating the registration. |
| EORI |
Customs operations and imports/exports. |
Discovering the need for EORI when the goods are already blocked. |
| High as a retainer |
Enter withholdings for employees, professionals or rents when applicable. |
Failure to submit periodic models due to not having identified the obligation from the beginning. |
Error 4: Incorrectly applying Spanish VAT and invoicing rules
VAT is one of the areas where foreign companies make the most mistakes. The problem isn't just the tax rate. Other factors include the location of the transaction, whether the client is a business or a consumer, whether there is an import, whether there is an intra-Community supply, whether the reverse charge mechanism applies, whether there are online sales, and whether the company is established for VAT purposes.
A single company may have operations subject to Spanish VAT, operations not subject to VAT, operations with reverse charge, imports with VAT on entry, intra-Community supplies, or B2C sales with special rules. Applying a single rule for everything usually leads to errors.
Common VAT mistakes when entering Spain
- Issuing invoices with Spanish VAT when the transaction is not located in Spain.
- Not charging VAT when it was appropriate to do so.
- Do not check if reverse charge applies.
- Failure to correctly register intra-community transactions.
- Not anticipating the impact of VAT on imports and customs.
- Failure to adapt invoicing to Spanish formal requirements.
- Do not coordinate VAT with logistics, e-commerce, warehouses or marketplaces.
Before selling in Spain, it's essential to map all the flows: who sells, from where, to whom, where the product is delivered, who imports, who stores, who invoices, and who collects payment. Without this map, VAT becomes a constant source of problems.
Error 5: Hiring in Spain without planning for the actual labor costs
Hiring staff in Spain involves more than just agreeing on a gross annual salary. Companies must consider collective bargaining agreements, job categories, working hours, vacation time, bonuses, employer social security contributions, occupational risk prevention, time tracking, teleworking policies, payroll, withholdings, and contract termination.
Many foreign companies underestimate the importance of collective bargaining agreements. In Spain, these agreements can determine minimum wages, bonuses, maximum working hours, probationary periods, allowances, leave entitlements, disciplinary procedures, and other elements that govern the employment relationship. Simply copying an international contract is not enough.
Common workplace mistakes
| Mistake |
Consequence |
How to avoid it |
| Hiring someone who works as an employee as a self-employed worker |
Risk of false self-employment, labor claims and regularization of contributions. |
Analyze dependence, alienation, schedule, means of work and actual organization. |
| Failure to identify the applicable collective agreement |
Incorrect salaries, unpaid bonuses, or incorrectly calculated working hours. |
Review activity, workplace, functions and territorial scope. |
| Failure to obtain a Contribution Account Code when applicable |
Inability to properly manage registrations and quotes. |
Plan your business registration before hiring. |
| Using foreign contracts without adaptation |
Clauses that are ineffective or incompatible with Spanish labor law. |
Draft local contracts in accordance with the Statute and agreement. |
| Failing to anticipate the cost of dismissal |
Incomplete staff budgets and poorly calculated decisions. |
Simulate extinction scenarios and risks of impropriety or nullity. |
If you're going to hire workers in Spain, don't start with the contract: start with a labor market analysis. At MGI Àmbit, we review collective bargaining agreements, total costs, payroll, social security contributions, and risks before your company makes any commitments.
Error 6: Not preparing Spanish accounts from day one
A foreign company operating in Spain needs reliable accounting information from the outset. It's not enough to simply maintain the accounts at the parent company and translate the data at year-end. If there is a subsidiary, branch, or permanent establishment, there will be accounting, tax, and registration obligations that require organized, traceable data adapted to Spanish regulations.
The common mistake is putting off local accounting. At first, it seems like there isn't enough volume, but within a few months, invoices, expenses, payroll, receipts, contracts, collections, payments, imports, withholdings, and transactions with the parent company accumulate. Rebuilding everything afterward is more expensive and less secure than designing the workflow correctly from the start.
What should be defined from the beginning
- Accounting plan and criteria for allocating income and expenses.
- Flow of invoices issued and received.
- Responsible for approving expenses in Spain.
- Relationship between local accounting and group reporting.
- Expense policy for relocated employees and managers.
- Treatment of transactions with the parent company and other related companies.
- Calendar of monthly, quarterly and annual closings.
- Documentary archive and evidence of each operation.
Error 7: Failure to document operations linked to the matrix
When a subsidiary, branch or permanent establishment in Spain works with its foreign parent company, intragroup operations appear: management services, software licenses, royalties, loans, cost rebilling, merchandise purchases, staff transfer, marketing, technical support or strategic management.
These transactions cannot be valued arbitrarily. They must adhere to market criteria and be properly documented. The most common mistake is charging expenses from the parent company to the Spanish entity without a contract, allocation method, evidence of services rendered, or economic analysis. This can lead to tax adjustments and disputes regarding deductibility.
| Intragroup transaction |
Usual risk |
Recommended document |
| Management fees |
Unjustified or non-deductible expense. |
Service contract, activity report and allocation criteria. |
| Trademark or technology assignment |
Royalty without financial support. |
License agreement and market value analysis. |
| Intragroup loans |
Non-comparable interest rate or lack of contract. |
Financing agreement, amortization schedule and comparables. |
| Cost rebilling |
Global costs allocated without traceability. |
Objective distribution criteria and supporting documentation. |
| Purchase of merchandise from the parent company |
Margins not aligned with functions and risks. |
Transfer pricing policy and functional analysis. |
Mistake 8: Underestimating bank, notary, translation and apostille processing times
Entering Spain depends not only on the Tax Office or the Commercial Registry. Banks, notaries, sworn translations, apostilles, powers of attorney, certificates of existence of the foreign company, identification of beneficial owners, and internal compliance processes are also involved.
Many foreign companies prepare an aggressive business plan and then discover that opening a bank account, accepting foreign documentation, or obtaining valid powers of attorney takes longer than anticipated. This can delay incorporation, banking operations, contract signing, or payroll payments.
A successful implementation requires preparing international documentation in advance: certificates from the foreign registry, current statutes, powers of the representative, shareholding structure, ultimate beneficiaries, sworn translations, apostilles or legalizations, and identity documentation of administrators.
Error 9: Using international contracts without adaptation to Spain
Commercial contracts that work in another country don't always work the same way in Spain. Foreign companies may need to adapt general terms and conditions, distribution agreements, agency agreements, service agreements, sales contracts, licenses, e-commerce terms, warranties, return policies, or supplier agreements.
This is especially important in matters relating to consumer relations, employment contracts, exclusive distribution agreements, commercial agency agreements, data protection, intellectual property, payment terms, dispute resolution, and jurisdiction. A clause drafted using Anglo-Saxon, French, German, or Latin American legal logic may produce undesirable results under Spanish law.
Contracts that should be reviewed before operating
- Contracts with distributors and sales agents.
- General terms and conditions of sale B2B and B2C.
- Service provision contracts.
- Employment contracts and confidentiality agreements.
- Partner agreements or joint ventures.
- Office, warehouse or premises rental agreements.
- Brand, software or technology licenses.
- Intragroup contracts between parent company and Spanish subsidiary.
Error 10: Failure to review licenses, sectoral permits and regional regulations
Spain has state, regional, and municipal regulations. A foreign company can formally comply with its tax and commercial obligations, but may require a municipal license, prior notification, sector-specific authorization, registration in an administrative registry, or specific compliance with a regional government.
This point is especially relevant in industrial, health, food, transport, training, telecommunications, energy, construction, financial services, regulated activities, retail, tourist rental, import of products or businesses with premises open to the public.
In Catalonia, there may also be linguistic, administrative or sectoral obligations that should be reviewed if the entry is made from Barcelona or with a presence in Catalan territory.
Error 11: Failure to coordinate taxation, labor, accounting and business
One of the most serious mistakes is treating each area separately. The company talks to a corporate lawyer, then to a payroll consultant, then to a tax advisor, and finally to the parent company's finance team. If no one coordinates the whole process, contradictions arise.
For example: the chosen business structure may not align with the tax strategy. The employment contract may not reflect the actual cost approved by finance. The transfer pricing policy may not be aligned with the accounting records. The distributor agreement may create a permanent establishment risk. Invoicing may be designed without considering VAT or logistics.
Entering the Spanish market should be managed as a comprehensive project. A roadmap is needed that connects business decisions with the tax, labor, accounting, and legal implications.

Conclusion: Entering the Spanish market requires more than just selling
The Spanish market offers real opportunities for foreign companies, but entering successfully requires planning. The most costly mistake is usually starting operations before defining the appropriate tax, commercial, labor, and accounting structure.

Frequently asked questions about foreign companies entering the Spanish market
What is the first step for a foreign company to enter Spain?+
The first step should be a tax, commercial, and labor audit. Before selling, hiring, or opening an office, it's advisable to decide whether the company will operate through direct sales, distribution, agents, branches, subsidiaries, or permanent establishments.
Does a foreign company need a Spanish NIF (tax identification number) to operate?+
In many cases, yes, especially if you plan to carry out tax procedures, establish a subsidiary, open a branch, hire staff, purchase certain assets, issue invoices from Spain, or fulfill obligations to the Spanish Tax Agency. The specific need depends on the entry model.
Which is better for entering Spain: a subsidiary or a branch?+
There is no single answer. A subsidiary has its own legal personality and usually offers a clearer separation from the parent company. A branch does not create an independent company and can be useful in certain business models. The choice depends on liability, taxation, control, costs, banking, employees, and growth strategy.
Can a foreign company hire workers in Spain without a subsidiary?+
There may be ways to hire in Spain without a subsidiary, but these should be carefully reviewed. If the company acts as the employer, it will have obligations regarding Social Security, payroll, withholding taxes, occupational health and safety, and Spanish labor law. Furthermore, the presence of workers may have tax implications.
What are the risks of selling in Spain without declaring a permanent establishment?+
If the business activity in Spain meets the requirements for a permanent establishment and is not declared, the company may face tax audits, interest charges, penalties, and deductibility issues. Therefore, it is essential to analyze functions, personnel, facilities, contracts, and decision-making capacity.
What VAT mistakes do foreign companies make in Spain?+
The most common errors are charging VAT when it is not applicable, not charging it when it is appropriate, not applying the reverse charge mechanism correctly, not reviewing intra-community transactions, not anticipating import VAT, and not adapting invoicing to Spanish regulations.
Why is it advisable to have local advisors before entering Spain?+
Because initial decisions determine all subsequent operations. A local advisor can review taxation, legal structure, hiring, VAT, accounting, banking, permits, and contracts before the company makes commitments that are difficult to rectify.
