Why the Typical EOR Structure Can Create Legal and Tax Risks, and How to Hire Compliantly in Spain
Lawants Guide · Employer of Record in Spain An Employer of Record is commonly proposed to foreign companies that want to hire in Spain without first establishing a subsidiary or branch. The Spanish provider signs the employment contract, registers the employee with Social Security and runs payroll, while the foreign company usually selects the person and directs the day-to-day work. The model therefore appears to offer local employment without local infrastructure.
That division of roles is also the source of its legal weakness. Spain does not recognise the EOR as a separate legal category. If the provider is the employer on paper while the foreign company exercises the employer powers in practice, the arrangement may amount to illegal worker supply. The first decision is therefore not who will run payroll, but which legal and tax structure can support the hire. This guide explains how to make that choice and which alternatives are available in Spain.
What Is an Employer of Record in Spain and How Does It Work?
An Employer of Record in Spain is a local provider that signs the employment contract, registers the employee with Spanish Social Security and operates payroll on behalf of a foreign company.
The model is typically proposed to hire in Spain without immediately setting up a Spanish company, to speed up onboarding, to delegate payroll and recurring filings, to obtain a contract that follows Spanish employment law, and to manage withholding, Social Security contributions and benefits without building local HR capacity.
For a foreign company, the attraction is clear: the provider appears to remove the registrations and administrative infrastructure required to employ locally. But administrative convenience does not determine who the employer is under Spanish law.
Payroll and compliance tasks can be outsourced; the employer role and its related liabilities cannot simply be transferred by contract.
What the EOR Typically Handles
- Spanish employment contract
- employee registration
- payroll and payslips
- IRPF withholding
- Social Security contributions
- benefits administration
- employment documentation
- onboarding and offboarding support
What the Foreign Company Usually Continues to Control
- selection of the employee
- role and remuneration
- daily tasks and priorities
- reporting lines
- performance evaluation
- strategic decisions
- continuation or termination of the engagement
The two lists reveal the central tension in the EOR model. The provider may produce the formal employment records while the foreign company retains the powers normally exercised by the employer.
In Spain, that mismatch can create employment and tax exposure even when the contract, payroll and filings are technically correct.

Is an Employer of Record Legal in Spain?
The division of roles described above can correspond to very different legal arrangements. The term Employer of Record does not determine which one applies, because Spain does not recognise the EOR as a separate legal category or provide a specific EOR authorisation.
Three structures are often confused:
- Payroll outsourcing: the foreign company remains the legal and actual employer, while a Spanish provider manages payroll and local filings.
- Genuine outsourcing: the provider organises and directs its own personnel to deliver an autonomous service or defined result.
- Worker supply: one company signs the employment contract, but another company directs the individual’s work.
The typical EOR risk arises in the third structure. If the Spanish provider is the employer on paper while the foreign company exercises the employer powers in practice, the arrangement may amount to illegal worker supply.
Payroll Outsourcing Keeps the Foreign Company as Employer
With payroll outsourcing, the foreign company hires the employee, directs the work and bears the employment risk. The Spanish provider calculates payroll, applies withholding and manages Social Security and recurring filings on that employer’s behalf.
This is a legitimate administrative service. The provider does not enter the employment relationship or present itself as the employer. A foreign company can often use this model after registering directly as an employer in Spain.
When an EOR May Amount to Illegal Worker Supply
A different situation arises when the Spanish provider signs the employment contract, but the foreign company continues to:
- select the worker and determine the remuneration;
- assign and supervise the work;
- control working time, leave and performance;
- decide whether the engagement continues or ends.
In that configuration, the provider may be formally identified as employer while the worker is effectively placed under the foreign company’s direction.
Spanish law reserves temporary worker supply to authorised temporary employment agencies, known as Empresas de Trabajo Temporal or ETTs, under Ley 14/1994. Outside that regulated channel, the arrangement may fall within Article 43 of the Spanish Workers’ Statute, which governs illegal worker supply.
ETT authorisation is not a general licence to place permanent employees under another company’s direction. The assignment must also fall within the temporary situations permitted by Ley 14/1994.
What Does Not Make an EOR Structure Compliant
Two common provider claims do not resolve the legal analysis:
- Owning the Spanish entity that signs the contract is not enough. The relevant question is which company actually exercises the employer functions, not whether the provider uses its own entity or a local partner.
- Calling the agreement consultancy or outsourcing does not change its substance. If the foreign company directs the individual’s daily work, Spanish authorities can look beyond the commercial label.
A Spanish contract, accurate payroll and timely filings can document an arrangement. They do not make the provider the genuine employer if the employer powers remain with the foreign company.
What Are the Legal Risks of Using an EOR in Spain?
The EOR may be named as employer, but the legal and tax exposure does not necessarily remain with the provider. If the arrangement amounts to illegal worker supply, the foreign company can also face direct liability, worker claims, administrative fines and permanent establishment exposure.
Four risks must be considered separately: the consequences imposed by Article 43, the limits of contractual indemnities, the foreign company’s corporate tax position and the consistency of the immigration and Social Security structure.
Joint Liability and Fines
EOR Indemnity Limits
Permanent Establishment Risk
Immigration and Social Security Mismatch
Illegal Worker Supply Can Trigger Joint Liability, Worker Claims and Fines
Where Article 43 applies, the consequences extend to both the Spanish provider and the foreign company:
- joint and several liability for salary and Social Security obligations under Article 43.3 of the Workers’ Statute;
- the worker’s right to acquire permanent employee status with either company, at their own choice, under Article 43.4;
- classification as a very serious employment infringement under Article 8.2 LISOS;
- administrative fines currently ranging from approximately €7,501 to €225,018 under the general bands established by Article 40 LISOS;
- further administrative or judicial consequences depending on the facts.
These consequences are not confined to the EOR provider. The foreign company receiving and directing the work can be pursued directly.
EOR Indemnities Do Not Remove the Foreign Company’s Liability
The EOR agreement may require the provider to cover or reimburse certain costs if the structure is challenged. It cannot prevent statutory liability from applying to the foreign company where Spanish law identifies illegal worker supply or another employment infringement.
Three separate issues are often confused:
- Contractual indemnity: what the provider agrees to cover under the commercial agreement.
- Statutory liability: what Spanish law imposes directly on the foreign company, regardless of the contract.
- Practical recovery: whether the foreign company can recover the amount from the provider after an authority or worker has already pursued it.
A well-drafted indemnity clause may regulate the relationship between the two companies. It does not change which parties Spanish authorities or the worker can hold liable.
A Spain-Based Employee Can Create a Permanent Establishment for the Foreign Company
Using an EOR does not prevent activities performed in Spain from creating a permanent establishment for the foreign company. The contractual employer and the corporate tax position are separate legal questions.
Under Article 13 TRLIRNR and Article 5 of the applicable tax treaty, the analysis considers:
- whether the foreign company has a place of business available in Spain;
- which activities the employee performs;
- whether the employee concludes, negotiates or plays a leading role in securing contracts.
Permanent establishment is not automatic. If one exists, the profits attributable to the Spanish activity may become subject to Spanish corporate taxation.
The EOR may change the name appearing on the employment contract. It does not remove the activities performed in Spain for the foreign company.
An EOR Does Not Resolve Immigration or Social Security Compliance
An EOR contract does not automatically confer the right to work in Spain or determine which Social Security system applies. A temporary posting and a local Spanish hire follow different rules, and the correct route depends on the underlying relationship rather than the company named on the contract.
The employment, tax, Social Security and immigration records must all describe the same situation. When an EOR is interposed for administrative convenience without performing the employer role in practice, those records can diverge. That inconsistency may become a central issue during a later employment, tax or Social Security review.
These risks can be difficult to justify when the foreign company could remain the genuine employer and comply directly with Spanish registration, payroll and Social Security obligations. Read our full guide to Employer of Record and Beckham Law reltionship.
How to Evaluate an EOR Proposal Before Signing
The relevant question is not only whether the provider has a Spanish entity or can generate a compliant contract. The company should ask how the proposed arrangement fits within Spanish employment law.
Confirm the Legal Basis
- Is the provider authorised as an ETT?
- If so, which permitted ground under Ley 14/1994 supports the temporary assignment?
- If not, what legal basis permits the foreign company to direct the worker?
Map the Employer Powers
- Who selects the worker and determines the remuneration?
- Who assigns work, supervises performance and approves leave?
- Who exercises disciplinary and termination authority?
Assess the Company-Side Exposure
- Which employment and Social Security liabilities remain with the foreign company?
- Has permanent establishment risk been assessed from the worker’s actual activities?
- Are immigration, Social Security and the applicable collective agreement aligned?
Compare the Alternatives
- Has direct foreign employer registration been evaluated?
- Would an authorised ETT, posting, subsidiary or branch better fit the activity?
- What happens to the worker and both companies if the arrangement is reclassified?
Further review is required when the provider will sign the contract and operate payroll, but the foreign company will retain recruitment, direction, performance management and termination in practice. A statement that the provider is the “legal employer” does not explain the legal basis of that division.
Before approving the proposal, the company should obtain a written explanation of the legal basis, a clear allocation of employer functions, the permanent establishment assessment and a comparison with direct foreign employer registration. Contractual assurances and indemnities are not substitutes for that analysis.
How Can a Foreign Company Hire Employees in Spain Without an EOR?
Once the EOR’s legal limits and the actual employer functions have been assessed, the next step is to identify the structure that fits the company’s activity in Spain.
There is no single alternative: the appropriate route depends on whether the company is making a first local hire, posting an existing employee, testing the market, building a permanent team or meeting a genuinely temporary staffing need.
The situations below provide a practical starting point. Each route must still be assessed against Spanish employment, tax, Social Security, immigration and permanent establishment requirements.
You Need to Hire 1–2 People in Spain
No Spanish entity planned, and the foreign company will keep directing the work.
→ Direct foreign employer registration
You’re Posting an Existing Employee to Spain
An existing employee will work in Spain for a genuinely limited assignment while remaining employed by the foreign company.
→ Temporary posting, Social Security and immigration assessment
You’re Scoping the Market Before Committing
The right answer depends on what that person actually does in Spain, not just their title.
→ Temporary presence, immigration and permanent establishment assessment
You’re Building a Team With Sustained Growth Expected
Multiple hires, recurring activity or a lasting commercial presence in Spain.
→ Spanish subsidiary or branch
You Need Temporary Staff in Spain
The business has a genuine temporary staffing need rather than a permanent role.
→ Authorised ETT
You’re Already Using an EOR in Spain
The arrangement is in place, and you want to know your actual exposure.
→ Structure and exposure review
These routes are not interchangeable.
Direct employment, temporary posting, authorised temporary worker supply and genuine outsourcing each follow a different legal framework. The sections below explain when each route may be available and what it requires.
A founder or controlling shareholder relocating to Spain requires a separate analysis based on ownership, effective control and employment status. See our guide to Beckham Law ownership thresholds for shareholder employees.
Register the Foreign Company as an Employer in Spain
Direct foreign employer registration begins with a preliminary review of the role, the employee and the activities planned in Spain, aligning the employment, tax, Social Security and immigration position before any filing. Once the route is confirmed, the foreign company obtains a Spanish NIF, appoints a local representative where required, registers with the Spanish Social Security Treasury and receives a Contribution Account Code (CCC).
The applicable collective bargaining agreement is then identified, the Spanish employment contract is prepared, the employee is registered and payroll begins.
- Structure Review Legal and tax analysis
- Company NIF Spanish identification
- TGSS and CCC Employer registration
- CBA and Contract Employment terms
- Employee and Payroll Social Security activation
- Ongoing Compliance Contributions and reporting
The foreign company remains the legal employer and a foreign legal entity throughout. Direct registration does not create a Spanish subsidiary, but it does not automatically resolve permanent establishment or immigration questions, which must still be assessed separately. Withholding, contributions and periodic reporting continue for as long as the employment relationship remains active.

Temporary Posting, Social Security and Immigration Assessment
A temporary posting allows an existing employment relationship with the foreign company to continue while the employee works in Spain for a genuinely limited assignment. Staying on foreign payroll does not, by itself, make the posting valid: it still needs to meet Social Security coordination requirements and the correct immigration route, and it needs to be genuinely temporary rather than a long-term local role structured to look like a posting.
Spanish Subsidiary or Branch
A subsidiary is a separate Spanish legal entity, while a branch is an extension of the foreign company itself and normally constitutes its permanent establishment in Spain. Both fit companies planning several hires, recurring Spanish activity or a lasting commercial presence, rather than a single temporary role.
See our guide to starting a business in Spain for how the two compare.
Authorised ETT
Where the need is a genuine, temporary staffing requirement rather than a permanent role, an authorised Empresa de Trabajo Temporal can supply workers within the conditions set by Ley 14/1994. This is the one route where a third party formally employing a worker who works under another company’s direction is expressly permitted by Spanish law, provided the assignment stays within an ETT’s authorised scope.
Genuine Outsourcing
Genuine outsourcing exists when a Spanish provider organises its own personnel and resources to deliver a defined result or service, and keeps directing that work itself. The foreign company receives an outcome, not day-to-day control over named individuals, which is what separates it from a provider that simply places a worker under the foreign company’s direction, whatever the commercial agreement calls it.

How Much Does an Employer of Record in Spain Cost?
Whichever route is used, most of the cost is the same, because it is set by Spanish law rather than by the hiring structure: gross salary, employer Social Security contributions (standard employer rates can amount to approximately 30.65% of the applicable contribution base, before occupational accident contributions, subject to annual rules and contribution limits), and other mandatory employment costs such as statutory leave and termination entitlements.
What changes between routes is the layer on top of that.
An EOR typically adds a recurring per-employee service fee, often with separate charges for onboarding and for ending the engagement. Direct foreign employer registration replaces that layer with the cost of the initial registration and, if desired, an ongoing payroll and compliance service. A Spanish subsidiary or branch adds its own setup and corporate maintenance costs, which may be justified where the Spanish activity extends beyond the employment relationship, regardless of headcount.
The comparison below sets out where each route actually differs.
| Issue | Typical EOR Proposal | Direct Foreign Employer Registration | Spanish Subsidiary | Branch |
|---|---|---|---|---|
| Legal employer | Spanish provider | Foreign company | Spanish entity | Foreign company, through the branch |
| Company directing the work | Often the foreign company | Foreign company | Spanish employer | Foreign company, through the branch |
| Separate Spanish legal entity | No | No | Yes | No, it is the foreign company itself |
| Provider interposition | Yes | No | No | No |
| Article 43 risk | Must be assessed | Normally not created by interposition | Normally not created by interposition | Normally not created by interposition |
| Payroll support | Included | Can be outsourced | Can be outsourced | Can be outsourced |
| Setup burden | Provider onboarding | Employer registration | Corporate establishment | Branch registration |
| Recurring obligations | Provider fee and employment costs | Payroll, tax and Social Security compliance | Employment plus corporate, accounting and tax compliance | Employment plus branch accounting and tax compliance |
| Permanent establishment analysis | Still required | Still required | Separate Spanish taxable entity; parent-company PE remains a separate analysis | Spanish permanent establishment of the foreign company |
| Typical fit | Only where the legal structure is supportable | Direct long-term employment without a Spanish subsidiary | Lasting Spanish operations as a distinct legal entity | Lasting Spanish operations as an extension of the foreign company |
What Employment, Payroll and Social Security Obligations Apply When Hiring in Spain?
Choosing the hiring structure identifies the legal employer, but it does not complete the Spanish employment setup. The employer must still apply the correct collective bargaining agreement, issue the contract, register the employee, operate payroll and comply with Spanish employment, Social Security and reporting rules.
These administrative functions can be outsourced without transferring the employer role to an EOR. A foreign company can remain the legal and actual employer while a Spanish adviser manages the local implementation and recurring compliance.
Apply the Correct CBA and Employment Contract
The applicable collective bargaining agreement (CBA) may determine minimum remuneration, salary supplements, working time, professional classification and probation periods above the statutory minimum.
An indefinite contract is the default, while fixed-term contracts require a specific legal justification. A Spanish or bilingual contract should contain the mandatory information and accurately reflect the real relationship, including any remote-working arrangement.
Register the Employee and Run Spanish Payroll
The employee must be registered with Spanish Social Security before work begins. Payroll then operates monthly, with IRPF withheld at source and employee and employer Social Security contributions calculated and paid.
The employer must also issue payslips and complete the required periodic and annual reporting. Additional salary payments, known as pagas extraordinarias, may be paid separately or prorated across the year where permitted by the applicable CBA. An entitlement expressed as 12 or 14 instalments does not necessarily require fourteen separate payroll runs.
Manage Working Time, Leave and Remote Work
The employer must comply with statutory and CBA rules governing working time, time recording, annual leave, public holidays and protected absences.
Remote work does not remove these obligations. The arrangement may require specific documentation, and occupational risk prevention measures must still cover the employee’s actual place of work.
Align Immigration, Termination and Ongoing Compliance
The employment structure must be consistent with the individual’s right to work in Spain. EU and non-EU nationals follow different requirements, while temporary postings, international telework and intra-company transfers are governed by separate rules.
Termination also requires a Spanish assessment of the legal grounds, procedure, notice and potential severance. An EOR contract does not remove these requirements or prevent liability from reaching the foreign company where the underlying structure is defective.
The key distinction is between outsourcing employment administration and transferring the employer role. Lawants can manage Spanish contracts, Social Security registration, payroll, withholding and recurring reporting while the foreign company remains the genuine employer and continues to direct the work. This provides local operational support without creating the employer interposition that can make the typical EOR structure problematic.
How Lawants Helps Foreign Companies Hire Compliantly in Spain
Whichever situation matches your company, from a single hire to a founder relocating with a controlling stake, Lawants starts from the same question: which company actually exercises the employer’s powers, and which structure lets the documentation describe that reality accurately.
Before any filing or registration, the preliminary assessment brings together Spanish employment law, tax, Social Security, immigration and permanent establishment. For founders and controlling shareholders, it also considers ownership, the correct Social Security classification, the director route and the design and documentation of access to Article 93 where viable.
Once the appropriate route has been defined, Lawants implements and manages the Spanish side of the structure. This may include registering the foreign company as an employer, preparing Spanish employment contracts, registering employees, operating payroll and managing recurring filings and reporting. Where the activity requires a lasting Spanish presence, Lawants can instead establish the appropriate subsidiary or branch and address the related corporate and cross-border tax position.
The same multidisciplinary team follows the structure after implementation and coordinates the Spanish work with the company’s home-country advisers, keeping the employment, tax, Social Security, immigration and corporate positions aligned as the activity develops.
Build the Right Spanish Employment Structure from the Start
The assessment identifies the route that best fits the company’s activity and plans in Spain. If the project proceeds, the same Lawants team implements the structure and manages employer registration, contracts, payroll, tax, Social Security and recurring compliance as the business develops.
EOR (Employer of Record in Spain): FAQ
Before relying on an EOR, a foreign company should understand what the label does and does not establish under Spanish law. The answers below cover the legality of the model, the distinction between an EOR and an authorised ETT, direct foreign employer registration and the consequences of reclassification.
Is an Employer of Record Legal in Spain?
An EOR label does not establish legality: EOR is a commercial term, not a distinct legal category under Spanish law. If the Spanish provider formally employs the worker while the foreign company directs the work, the arrangement may constitute illegal worker supply under Article 43 of the Workers’ Statute. Temporary worker supply must operate through an authorised ETT and within the conditions permitted by Ley 14/1994. A provider that independently organises its own personnel to deliver an autonomous service may instead qualify as genuine outsourcing.
Is an EOR the Same as an Authorised ETT in Spain?
No. EOR is a commercial label, while an ETT is a statutory category subject to authorisation and the conditions of Ley 14/1994. In Case C-441/23, the CJEU held that EU temporary agency work protections may apply according to the substance of an arrangement even when the provider lacks domestic authorisation. The judgment does not itself grant ETT authorisation or make the assignment lawful under Spanish law.
Can an EOR Provider Guarantee Compliance in Spain?
A provider can prepare a compliant Spanish contract, run payroll correctly and file Social Security on time. None of that validates the underlying relationship, because that depends on how the foreign company actually manages the worker day to day, which is outside the provider’s control.
Does Owning a Spanish Entity Make an EOR Provider Compliant?
Owning the local entity avoids relying on a third-party partner, which can matter for continuity and accountability. It does not, by itself, resolve the Article 43 analysis. What determines the outcome is which company exercises the employer’s functions in practice, regardless of who owns the entity that signs the contract.
Do I Need a Spanish Entity to Hire One Employee?
Not necessarily. A foreign company can often register directly as a non-resident employer in Spain, obtain the required tax and Social Security identifiers, and employ one or two people without incorporating a subsidiary or interposing an EOR.
What Happens if an EOR Arrangement Is Reclassified as Illegal Worker Supply?
Both the Spanish provider and the foreign company can be held jointly liable for salary and Social Security obligations, the worker can choose to become a permanent employee of either company, and the infringement is classified as very serious under Article 8.2 LISOS. Illegal worker supply and permanent establishment are separate legal analyses: a finding on one does not automatically determine the other, even though both can rest on the same facts about who actually directs the work in Spain.
