Entering the Spanish market can be a major opportunity for a foreign company: access to European customers, qualified talent, infrastructure, ports, airports, industrial suppliers, technology hubs and a strategic position from which to operate in Southern Europe. But it can also become a source of problems if the market entry is improvised.
Many international companies start with the commercial side: they look for distributors, sign contracts, hire a local salesperson or open a representative office. The problem arises when that activity creates tax, employment, accounting or corporate obligations that had not been anticipated. In Spain, entering the market incorrectly is often costly: incorrect tax registrations, permanent establishment risks, misapplied VAT, deficient employment contracts, Social Security problems, banking delays or inefficient corporate structures.
In MGI Àmbit, a firm of lawyers and economists in Barcelona, we help foreign companies establish themselves in Spain with an integrated approach: international taxation, corporate structure, accounting, payroll, employment compliance and operational planning. In this guide, we analyse the most common mistakes foreign companies make when entering the Spanish market and how to avoid them before they lead to penalties, costs or operational roadblocks.
Quick summary
- Purpose of the article: identify the mistakes foreign companies most commonly make when starting operations in Spain.
- Who it is for: foreign parent companies, international groups, startups, industrial companies, e-commerce businesses, professional services firms and companies seeking to enter the Spanish market.
- Key mistakes: choosing the wrong market-entry structure, ignoring permanent establishment risk, misapplying VAT, hiring without employment planning and failing to set up local accounting.
- Main risk: starting commercial operations before correctly defining the tax position, legal structure and administrative obligations.
- Solution: carry out a preliminary Spanish market-entry assessment with coordinated tax, employment, accounting and corporate advice.
Why foreign companies make mistakes when entering Spain
Most mistakes do not occur because companies are unwilling to comply with the law. They occur because a company applies in Spain the same logic it uses in its home country. However, every market has its own rules: tax obligations, administrative deadlines, employment formalities, Spanish Tax Agency criteria, commercial registers, collective bargaining agreements and accounting documentation.
A foreign company may have a perfectly valid model in its home country and still create liabilities in Spain if it does not adapt its structure. For example, selling from the parent company without analysing whether there is a fixed presence can create a permanent establishment risk. Engaging a Spanish professional as self-employed when that person actually works as an employee can lead to employment-law problems. Using international contracts without local review can leave clauses ineffective or conflictual.
For this reason, entering Spain should not be treated as a simple administrative formality. It should be approached as an implementation project combining taxation, corporate law, employment, accounting, treasury, banking, invoicing and reporting.
Mistake 1: failing to define the market-entry structure before starting to sell
The first mistake is entering the Spanish market commercially without deciding what legal and tax structure will support that activity. Some companies start with a local salesperson, an agency agreement, a logistics warehouse or agreements with Spanish customers without analysing whether that presence requires registration, opening a branch, incorporating a subsidiary or declaring a permanent establishment.
The market-entry structure should be decided before signing significant contracts. Selling from abroad is not the same as operating through a Spanish subsidiary. Nor is opening a branch the same as acting through an independent distributor. Each option changes the level of control, liability, taxation, accounting obligations and management costs.
| Entry structure |
When it may fit |
Risk if chosen incorrectly |
| Direct sales from abroad |
Limited operations, with no office, employees or fixed presence in Spain. |
Incorrect application of VAT, logistics, warranties, contracts or indirect taxation. |
| Local distributor |
The company wants to sell in Spain without its own structure and with an independent commercial partner. |
Loss of control over the brand, pricing, customers or service quality. |
| Commercial agent |
The company wants to win customers with local support but without initially creating a Spanish company. |
Tax risk if the agent has authority to contract or acts dependently. |
| Branch |
Stable activity in Spain without creating a legal entity separate from the parent company. |
Direct liability of the parent company and specific registration and accounting obligations. |
| Spanish subsidiary |
Long-term project, local hiring, Spanish invoicing and a long-term growth strategy. |
Higher initial cost, but greater operational and tax clarity. |
| Permanent establishment |
Continuous activity exists in Spain without a local company having been incorporated. |
Risk of tax reassessment if the company does not recognise it or tax it correctly. |
Does your company want to enter Spain but you are unsure whether to operate through a subsidiary, branch, distributor or permanent establishment? At MGI Àmbit, we analyse your case and design the safest tax, employment and accounting structure so you can start on the right footing.
Mistake 2: ignoring permanent establishment risk
A permanent establishment is one of the most sensitive issues for a foreign company. Many companies believe that as long as they do not create a Spanish company, they have no significant tax obligations in Spain. That assumption is dangerous.
A permanent establishment may exist when a non-resident company carries on business in Spain through facilities, workplaces, offices, warehouses, places of management or agents who habitually have authority to conclude contracts. In practice, the risk arises when the company has a stable local presence, even if it formally continues to invoice from the foreign parent company.
The mistake is not only failing to declare it. It also involves failing to document correctly which income and expenses relate to the Spanish activity, not keeping separate accounting records or not properly applying related-party transaction rules between the head office and the activity in Spain.
Warning signs of a possible permanent establishment
- The company has an office, premises, warehouse or stable sales team in Spain.
- There are personnel in Spain who negotiate or conclude contracts on behalf of the parent company.
- Services are provided continuously from Spanish territory.
- There is an effective place of management or operational decision-making centre in Spain.
- Material or human resources in Spain are regularly used to generate income.
- The parent company invoices from abroad, but the actual economic activity is carried out wholly or partly in Spain.
The solution is not to conceal the operations, but to structure them correctly. In some cases, adjusting contracts and functions will be sufficient. In others, it will be necessary to declare a permanent establishment, open a branch or incorporate a subsidiary.
Mistake 3: applying too late for the tax ID number, Form 036 and tax registrations
Another very common mistake is thinking that the company can start operating and regularise its position later. In Spain, certain registrations must be completed correctly before starting the activity, issuing invoices, hiring employees, importing goods or withholding taxes.
The census declaration using Form 036 is a key document because it informs the Spanish Tax Agency of essential data: identification, activity, VAT obligations, withholdings, tax address, representatives, premises, tax regimes and other relevant circumstances. A wrongly selected box can create incorrect obligations or omit filings that the tax authorities may later demand.
| Procedure |
What it is for |
Common mistake |
| Tax ID number for a foreign or Spanish entity |
Tax identification before the Spanish Tax Agency. |
Applying for it too late and delaying contracts, banking, invoicing or registrations. |
| Form 036 |
Registration, amendment or deregistration in the census of businesses, professionals and withholding agents. |
Incorrectly selecting VAT, withholding or business-activity obligations. |
| ROI / VIES |
Intra-Community transactions where applicable. |
Issuing or receiving intra-Community invoices without correctly validating registration. |
| EORI |
Customs operations and imports/exports. |
Discovering that an EORI is required when the goods are already blocked. |
| Registration as a withholding agent |
Paying withholdings on employees, professionals or rent where applicable. |
Failing to file periodic returns because the obligation was not identified from the outset. |
Mistake 4: misapplying Spanish VAT and invoicing rules
VAT is one of the areas where foreign companies make the most mistakes. The issue is not only the tax rate. The place of supply also matters, as does whether the customer is a business or a consumer, whether there is an import, whether there is an intra-Community supply, whether the reverse charge applies, whether there are online sales, and whether the company is established for VAT purposes.
The same company may have transactions subject to Spanish VAT, transactions outside the scope of Spanish VAT, reverse-charge transactions, imports with import VAT, intra-Community supplies or B2C sales subject to special rules. Applying a single rule to everything usually leads to errors.
Common VAT mistakes when entering Spain
- Issuing invoices with Spanish VAT when the transaction is not located in Spain.
- Failing to charge VAT when it should have been charged.
- Failing to check whether the reverse charge applies.
- Failing to register intra-Community transactions correctly.
- Failing to anticipate the VAT impact on imports and customs.
- Failing to adapt invoicing to Spanish formal requirements.
- Failing to coordinate VAT with logistics, e-commerce, warehouses or marketplaces.
Before selling in Spain, it is advisable to map all flows: who sells, from where, to whom, where the product is delivered, who imports, who stores, who invoices and who collects payment. Without that map, VAT becomes a constant source of tax exposure.
Mistake 5: hiring in Spain without planning the real employment cost
Hiring staff in Spain is not just about agreeing an annual gross salary. The company must take into account the applicable collective bargaining agreement, professional category, working hours, holidays, extra salary payments, employer Social Security contributions, occupational risk prevention, time recording, remote-working policy, payroll, withholdings and termination of employment.
Many foreign companies underestimate the importance of collective bargaining agreements. In Spain, the applicable agreement may determine the minimum salary for the category, allowances, maximum working time, probation period, expenses, leave, disciplinary rules and other elements that shape the employment relationship. Simply copying an international employment contract is not enough.
Common employment mistakes
| Mistake |
Consequence |
How to avoid it |
| Engaging as self-employed someone who actually works as an employee |
Risk of false self-employment, employment claims and reassessment of Social Security contributions. |
Analyse dependence, integration into the organisation, working hours, work tools and the actual way the work is organised. |
| Failing to identify the applicable collective bargaining agreement |
Incorrect salaries, unpaid allowances or incorrectly calculated working hours. |
Review the activity, workplace, duties and territorial scope. |
| Failing to obtain an Employer Social Security Contribution Account Code when required |
Inability to manage employee registrations and Social Security contributions correctly. |
Plan the employer registration before hiring. |
| Using foreign contracts without adaptation |
Ineffective clauses or clauses incompatible with Spanish employment law. |
Draft local contracts in accordance with the Workers’ Statute and the applicable collective agreement. |
| Failing to anticipate dismissal costs |
Incomplete personnel budgets and poorly calculated decisions. |
Model termination scenarios and risks of unfair or null dismissal. |
If you are going to hire employees in Spain, do not start with the contract: start with an employment assessment. At MGI Àmbit, we review the collective agreement, total cost, payroll, Social Security and risks before your company makes commitments.
Mistake 6: failing to set up Spanish accounting from day one
A foreign company operating in Spain needs reliable accounting information from the outset. It is not enough to keep the accounting at the parent company and translate the data at the end of the year. If there is a subsidiary, branch or permanent establishment, there will be accounting, tax and registration obligations requiring orderly, traceable data adapted to Spanish regulations.
The common mistake is leaving local accounting for later. At first, it may seem that there is not enough volume to justify it, but within a few months invoices, expenses, payroll, receipts, contracts, collections, payments, imports, withholdings and transactions with the parent company accumulate. Reconstructing everything retrospectively is more expensive and less secure than designing the process correctly from the start.
What should be defined from the outset
- Chart of accounts and criteria for allocating income and expenses.
- Flow of issued and received invoices.
- Person responsible for approving expenses in Spain.
- Relationship between local accounting and group reporting.
- Expense policy for employees and seconded executives.
- Treatment of transactions with the parent company and other related entities.
- Schedule for monthly, quarterly and annual closings.
- Document filing and evidence for each transaction.
Mistake 7: failing to document related-party transactions with the parent company
When a subsidiary, branch or permanent establishment in Spain works with its foreign parent company, intragroup transactions arise: management services, software licences, royalties, loans, cost recharges, purchases of goods, staff secondments, marketing, technical support or strategic management.
These transactions cannot be valued arbitrarily. They must comply with market-based criteria and be documented. The most common mistake is charging expenses from the parent company to the Spanish entity without a contract, allocation method, evidence of the service provided or economic analysis. This can lead to tax adjustments and disputes over deductibility.
| Intragroup transaction |
Common risk |
Recommended document |
| Management services or management fees |
Unsupported or non-deductible expense. |
Services agreement, activity report and allocation method. |
| Transfer of brand or technology |
Royalty without economic support. |
Licence agreement and market-value analysis. |
| Intragroup loans |
Non-arm’s-length interest rate or lack of a contract. |
Financing agreement, amortisation schedule and comparables. |
| Cost recharges |
Global costs allocated without traceability. |
Objective allocation method and supporting documentation. |
| Purchase of goods from the parent company |
Margins not aligned with functions and risks. |
Transfer-pricing policy and functional analysis. |
Mistake 8: underestimating the time required for banking, notaries, translations and apostilles
Entering Spain does not depend only on the tax authorities or the Commercial Registry. Banks, notaries, sworn translations, apostilles, powers of attorney, certificates proving the existence of the foreign company, identification of beneficial owners and internal compliance processes are also involved.
Many foreign companies prepare an aggressive commercial timetable and later discover that opening a bank account, getting foreign documentation accepted or obtaining valid powers of attorney takes longer than expected. This can delay incorporation, banking operations, contract signing or payroll payments.
A well-planned setup requires international documentation to be anticipated: certificates from the foreign registry, current articles of association, powers of attorney for the representative, shareholding structure, ultimate beneficial owners, sworn translations, apostilles or legalisations and identification documents for directors.
Mistake 9: using international contracts without adapting them to Spain
Commercial contracts that work in another country do not always work in the same way in Spain. A foreign company may need to adapt general terms and conditions, distribution agreements, agency agreements, service agreements, sale and purchase agreements, licences, e-commerce terms, warranties, return policies or supplier agreements.
This is especially important in consumer relationships, employment contracts, exclusive distribution, commercial agency, data protection, intellectual property, payment terms, dispute resolution and jurisdiction. A clause drafted according to Anglo-Saxon, French, German or Latin American legal logic may produce unintended results under Spanish law.
Contracts that should be reviewed before operating
- Agreements with distributors and commercial agents.
- General B2B and B2C terms and conditions of sale.
- Service agreements.
- Employment contracts and confidentiality agreements.
- Shareholders’ agreements or joint ventures.
- Lease agreements for offices, warehouses or premises.
- Brand, software or technology licences.
- Intragroup agreements between the parent company and the Spanish subsidiary.
Mistake 10: failing to review licences, sector permits and regional regulations
Spain has national, regional and municipal regulations. A foreign company may formally comply with its tax and corporate obligations but still need a municipal licence, prior notification, sector authorisation, registration with an administrative registry or specific compliance with rules of an autonomous community.
This is especially relevant in industrial, healthcare, food, transport, training, telecommunications, energy, construction, financial services, regulated activities, retail, tourist accommodation, product imports or businesses with premises open to the public.
In Catalonia, there may also be language, administrative or sector-specific obligations that should be reviewed if the market entry is carried out from Barcelona or with a presence in Catalan territory.
Mistake 11: failing to coordinate tax, employment, accounting and business matters
One of the most serious mistakes is handling each area separately. The company speaks to a corporate lawyer, then to an employment consultancy, then to a tax adviser and finally to the parent company’s finance team. If no one coordinates the whole picture, contradictions arise.
For example, the chosen corporate structure may not fit the tax strategy. The employment contract may not reflect the real cost approved by finance. The transfer-pricing policy may not be aligned with the accounting. The distributor agreement may create permanent establishment risks. Invoicing may be designed without considering VAT or logistics.
Entering Spain should be managed as a cross-functional project. There should be a roadmap connecting commercial decisions with their tax, employment, accounting and legal implications.

How MGI Àmbit helps foreign companies that want to enter Spain
MGI Àmbit supports foreign companies that want to start operating in Spain or review an operation that is already underway. Our approach combines tax, accounting, employment and legal advice to prevent the company from making isolated decisions that create problems later.
Initial implementation assessment
We analyse the business model, country of origin, customer type, planned presence in Spain, local team, logistics, invoicing, contracts and intragroup flows. With this information, we define the risks and available options.
Design of the tax and corporate structure
We help determine whether it is better to operate through a subsidiary, branch, permanent establishment, distributor, agent or another structure. We also review the tax impact of each option and the associated administrative obligations.
Tax, accounting and employment registrations
We coordinate census registrations, tax obligations, local accounting, payroll, Social Security, employment contracts and internal procedures so that the company can operate in an orderly manner.
Monthly follow-up and ongoing compliance
Once the structure is in place, we support the company with its recurring management: accounting, taxes, payroll, reporting, related-party transactions, employment queries and adaptation to regulatory changes.
Conclusion: entering Spain requires more than selling
The Spanish market offers real opportunities for foreign companies, but entering it correctly requires planning. The most expensive mistake is often starting operations before defining the appropriate tax, corporate, employment and accounting structure.
The most common problems—undeclared permanent establishment, misapplied VAT, improvised hiring, late accounting, undocumented intragroup transactions or contracts that have not been adapted—can be avoided with a proper preliminary assessment.
If your company wants to enter Spain, open a subsidiary, hire staff, sell to Spanish customers or review an operation that is already running, having a specialised local team can make the difference between an orderly implementation and a succession of problems.

Frequently asked questions about foreign companies entering the Spanish market
What is the first step for a foreign company entering Spain?+
The first step should be a tax, corporate and employment assessment. Before selling, hiring or opening an office, it is advisable to decide whether the company will operate through direct sales, a distributor, an agent, a branch, a subsidiary or a permanent establishment.
Does a foreign company need a Spanish tax ID number to operate?+
In many cases, yes, especially if it will carry out tax procedures, incorporate a subsidiary, open a branch, hire staff, purchase certain assets, issue invoices from Spain or comply with obligations before the Spanish Tax Agency. The specific requirement depends on the market-entry model.
What is better for entering Spain: a subsidiary or a branch?+
There is no single answer. A subsidiary has its own legal personality and usually provides a clearer separation from the parent company. A branch does not create an independent company and may be useful for certain models. The choice depends on liability, taxation, control, costs, banking, employees and growth strategy.
Can a foreign company hire employees in Spain without a subsidiary?+
There are ways to hire in Spain without a subsidiary, but they must be reviewed carefully. If the company acts as the employer, it will have Social Security, payroll, withholding, occupational risk prevention and Spanish employment-law obligations. The presence of employees may also have tax implications.
What is the risk of selling in Spain without declaring a permanent establishment?+
If the activity in Spain meets the requirements for a permanent establishment and it is not declared, the company may face tax reassessments, interest, penalties and deductibility issues. It is therefore essential to analyse functions, personnel, facilities, contracts and decision-making authority.
What VAT mistakes do foreign companies make in Spain?+
The most common mistakes are charging VAT when it should not be charged, failing to charge it when it should, incorrectly applying the reverse charge, failing to review intra-Community transactions, failing to anticipate import VAT and not adapting invoicing to Spanish rules.
Why is it advisable to have local advisers before entering Spain?+
Because initial decisions shape all subsequent operations. A local adviser can review taxation, legal form, hiring, VAT, accounting, banking, permits and contracts before the company makes commitments that are difficult to correct.
