Permanent Establishment in Spain

Permanent Establishment in Spain Explained

Understanding Permanent establishment in Spain is critical for foreign companies expanding into the Spanish market without forming a local subsidiary. Under Spanish tax law, a Permanent Establishment (PE) creates a taxable presence even if the foreign business has not incorporated a Spanish entity. 

In practical terms, a Spain PE arises when a non-resident company carries out business activities in the country through a fixed place of business or a dependent agent. Once triggered, the company becomes subject to corporate income tax, Value-Added Tax (VAT) obligations, payroll withholding, and broader compliance requirements.

Key Takeaways:

• A Permanent establishment in Spain creates taxable presence without incorporation, triggering corporate tax, VAT, payroll, and compliance obligations.
• Permanent establishment risk in Spain often arises unintentionally through employees, contract authority, warehouses, construction projects, or recurring executive presence.
• Spain permanent establishment rules follow domestic corporate tax law and OECD principles, requiring arm’s-length profit attribution and documentation compliance.
• Retroactive PE assessments may result in back taxes, interest, administrative penalties, transfer pricing adjustments, and reputational exposure for foreign companies.
• Incorporating a Spanish subsidiary often provides stronger liability protection, tax certainty, operational flexibility, and long-term scalability than operating through a PE.

Why Permanent Establishment Matters for Foreign Companies?

Under the permanent establishment rules in Spain, once activities meet the legal threshold, the foreign company becomes subject to Spanish taxation on profits attributable to that establishment. This applies even if the business believed it was only “testing the market.”

1. Financial Consequences of a Permanent Establishment

A PE triggers immediate tax and reporting implications. These may include:

• PE tax under Impuesto sobre la Renta de no Residentes (IRNR) on profits attributable to Spanish operations
• VAT registration and periodic VAT filings if taxable transactions occur locally
• Payroll withholding obligations and Social Security contributions if employees are hired

If a foreign PE is identified retroactively, the Agencia Estatal de Administración Tributaria (AEAT), which is the Spanish Tax Agency, may assess unpaid taxes, late-payment interest, and penalties. 

2. Operational and Compliance Impact

Beyond tax, the operational burden can be substantial. Once a PE exists, companies typically must:

• Register the PE with Spanish tax authorities
• Maintain separate accounting records for Spanish operations
• Attribute income and expenses according to the Organisation for Economic Co-operation and Development (OECD) principles

Failure to properly allocate profits can lead to disputes over taxable base calculations.

3. Unintentional PE During Early Expansion

One of the most common compliance failures occurs during early-stage growth. Companies often assume that limited activity does not create exposure. However, the following situations may trigger a PE:

• Hiring a local sales representative with authority to conclude contracts
• Engaging dependent agents who habitually negotiate core terms
• Leasing warehouse space for inventory storage and order fulfillment
• Operating a construction or installation project exceeding treaty time thresholds

Because these activities often occur before formal incorporation, they present heightened PE risk.

4. Interaction With Treaty Protection and Exemptions

In certain cases, a foreign permanent establishment exemption may prevent double taxation if a tax treaty applies. However, treaty relief does not eliminate Spanish filing obligations where a PE exists. It simply coordinates taxing rights between Spain and the company’s home country.

Legal Framework Governing Permanent Establishment in Spain

To properly assess PE in Spain, foreign companies must understand how Spanish domestic law defines and enforces PE status. Spain’s framework is grounded in statutory tax law and supported by international treaty principles. 

1. Domestic Legal Basis

The primary legislation governing a foreign permanent establishment is Article 13 defining when a non-resident entity is deemed to operate through a PE. Under this article, a PE generally exists when a non-resident entity:

• Has a fixed place of business in Spain where all or part of its activity is carried out
• Operates through a branch, office, factory, workshop, or similar facility
• Acts through an agent authorized to contract in the name of the foreign enterprise
• Carries out construction, installation, or assembly projects meeting applicable duration thresholds

These statutory provisions form the core PE criteria under domestic law.

2. Alignment With the OECD Model Tax Convention

Spain’s domestic definition is closely aligned with Article 5 of the OECD Model Tax Convention, which provides the internationally accepted framework for determining PE status in cross-border cases.

Spain incorporates OECD principles into its bilateral tax treaties, particularly regarding:

• Fixed place of business definitions
• Dependent agent rules
• Construction site duration thresholds
• Preparatory or auxiliary activity exceptions

This alignment is central when evaluating risk for companies headquartered in treaty jurisdictions.

3. Domestic Law vs. Tax Treaty Differences

It is critical to distinguish between domestic law and treaty protection:

• Domestic law determines whether Spain considers a PE to exist and imposes filing obligations.
• Tax treaties may limit Spain’s taxing rights if treaty PE thresholds are not met.

For example, domestic law may define a construction site as a PE, but a treaty may require the project to exceed a specific time threshold before taxation applies. If treaty conditions are not met, a foreign PE exemption may apply to prevent Spanish taxation.

Types of Permanent Establishment Recognized in Spain

Spain recognizes several forms of PE under domestic tax law and applicable tax treaties. Below are the main types:

1. Fixed Place Permanent Establishment

A fixed place PE arises when a foreign PE operates through a physical location in Spain where business activities are wholly or partly carried out.

Under Spanish law, this includes:

• Branches
• Offices
• Factories
• Workshops
• Warehouses used for core business operations

Practical examples:

• A foreign technology company opening a sales office in Madrid to negotiate and conclude contracts.
• A manufacturing business operating a production facility in Valencia.
• An e-commerce company maintaining a warehouse in Spain used for order fulfillment beyond merely preparatory or auxiliary activities.

These scenarios generally meet the PE criteria if the place of business has sufficient permanence and operational substance.

2. Dependent Agent Permanent Establishment

A dependent agent PE arises when a person in Spain acts on behalf of a foreign enterprise and has, and habitually exercises, authority to conclude contracts in the name of that enterprise.

Practical examples:

• A Spanish-based sales representative regularly signing contracts binding the foreign company.
• A local agent negotiating and finalizing commercial terms without material modification by headquarters.

This category often creates unintentional PE risk, particularly when companies rely heavily on local commercial representatives.

3. Construction or Installation Permanent Establishment

Spain recognizes construction, installation, and assembly projects as a distinct category of PE. However, the duration threshold may vary depending on whether a tax treaty applies.

Under domestic law, construction sites may constitute a PE if they demonstrate sufficient permanence. Under most tax treaties, a construction PE is triggered if the project exceeds a specific duration, commonly 12 months, but this depends on the treaty.

Practical examples:

• A foreign engineering firm supervising a 14-month infrastructure project in Spain.
• An installation contractor managing a long-term energy facility build-out exceeding treaty time limits.

Once the duration threshold is met, the project site becomes subject to PE tax on attributable profits.

Permanent Establishment Criteria in Spain

To accurately assess exposure under permanent establishment criteria in Spain, foreign companies must evaluate both statutory definitions under domestic law and refinements under applicable tax treaties. 

Below is a structured breakdown of the key elements used to determine whether a PE in Spain exists.

• Fixed Place of Business: A fundamental element of the PE criteria is the existence of a fixed place of business through which the company’s activity is wholly or partly carried out. If the location supports revenue-generating activity (not merely preparatory or auxiliary functions), a PE may arise.
• Permanence Requirement: The place of business must demonstrate a sufficient degree of permanence. Temporary or short-term presence typically does not meet the threshold unless treaty provisions provide otherwise.
• Disposal Test (Right of Use): Another critical component of PE criteria is the “disposal test.” The foreign enterprise must have the location at its disposal, meaning it can use the premises as its own for business purposes.
• Authority to Conclude Contracts: Even without a fixed place, a foreign PE may arise if a person in Spain has and habitually exercises authority to conclude contracts in the name of the foreign enterprise.

Companies expanding through hiring, warehousing, project execution, or contract-based services should apply a structured checklist before commencing operations to mitigate unexpected tax exposure.

Common Triggers of Permanent Establishment Risk in Spain

Understanding permanent establishment risk in Spain is essential for foreign companies entering the Spanish market without incorporating a subsidiary. Below are the most common real-world triggers that increase PE exposure.

1. Hiring Local Sales Employees

One of the most frequent causes of PE risk is hiring a locally based sales representative.

Risk increases when the employee:

• Negotiates key commercial terms
• Habitually secures orders
• Operates from a fixed location used for business

2. Granting Authority to Conclude Contracts

Granting formal or de facto authority to sign contracts in Spain significantly increases exposure under PE rules.

Risk factors include:

• Written authority to bind the foreign company
• Habitual contract execution
• Minimal review by headquarters

Once triggered, profits attributable to Spanish activity become subject to PE tax under IRNR rules.

3. Storing Inventory or Operating Warehousing

Warehousing and inventory storage can create PE risk depending on operational control and business purpose.

Exposure increases when:

• The foreign company leases warehouse space directly
• The warehouse supports order fulfillment or revenue-generating activities
• Inventory is regularly dispatched from Spain to customers

4. Recurring Executive or Management Presence

Repeated or sustained executive presence in Spain may indicate sufficient permanence or management activity.

Risk indicators include:

• Senior executives conducting strategic operations from Spain
• Regular board or management meetings held locally
• Long-term use of co-working or office facilities

This type of activity often goes unnoticed in early expansion stages but can materially increase compliance risk.

Once PE status is established, compliance obligations, and exposure to Spanish taxation follow automatically.

Does Remote Work Create a Permanent Establishment in Spain?

PE in Spain can arise even where a foreign company has no registered branch or leased office. Spanish tax analysis focuses on substance over form, meaning authorities assess how activities function in practice, not simply how contracts are drafted.

1. Home Office and the “At Disposal” Principle

A key question under PE criteria is whether a home office is considered “at the disposal” of the foreign company. According to OECD, a home office may create a PE where:

• The space is used on a continuous basis for business activities
• The company requires or effectively mandates remote work from Spain
• The business benefits from having a fixed operational base in Spain

The decisive factor is control and functional use, not whether the address is formally registered.

2. Employer Control and Business Integration

Under the PE rules, tax authorities examine whether the foreign company exercises meaningful control over the location and business activity.

Risk increases where:

• The employment contract specifies Spain as the work location
• The employee represents the company commercially in Spain
• Company materials, infrastructure, or equipment are dedicated to Spanish operations

If the employee has authority to bind the company, a dependent agent PE may arise even without a physical office.

3. Substance-Over-Form Approach

Spanish tax authorities apply a substance-over-form analysis when evaluating a foreign PE. This means:

• Labels such as “remote contractor” do not eliminate PE exposure if functional realities indicate otherwise.
• Avoiding a formal branch registration does not prevent a PE status if statutory thresholds are met.

Authorities focus on:

• Actual business functions performed in Spain
• Revenue-generating activity
• Decision-making authority exercised locally

This approach significantly increases PE risk for remote-first companies expanding informally.

Permanent Establishment Tax in Spain

The concept of permanent establishment tax in Spain does not create a separate tax regime. Instead, it applies existing corporate taxation principles to the Spanish activities of a non-resident entity.

Below is how PE tax in Spain operates in practice.

1. Corporate Income Tax Rate

A foreign PE in Spain is taxed similarly to a Spanish resident company on profits attributable to the PE. The general corporate income tax rate in Spain is 25% (subject to legislative change). Taxation applies only to profits economically attributable to the PE.

2. Profit Attribution on an Arm’s Length Basis

Under PE rules, profits must be determined as if the PE were a separate and independent enterprise performing similar functions under comparable conditions. This follows the arm’s length principle.

Profit attribution requires analysis of:

• Functions performed in Spain
• Assets used
• Risks assumed
• Internal dealings between the head office and the PE

Improper attribution significantly increases PE risk, particularly during audits.

3. Transfer Pricing Documentation

If transactions occur between the Spanish PE and its foreign head office or related entities, Spain’s transfer pricing rules apply. Spanish Corporate Income Tax Law requires documentation supporting arm’s length pricing for related-party transactions.

4. VAT Registration and Indirect Tax Obligations

If the PE carries out taxable supplies in Spain, VAT registration may be required.

This includes:

• Charging Spanish VAT on local sales
• Filing periodic VAT returns
• Complying with invoicing and reporting rules

VAT exposure is separate from corporate income tax and may arise even before profit attribution is finalized.

Foreign Permanent Establishment and Double Tax Treaties

When a foreign PE is created, cross-border tax exposure becomes a central issue. While Spanish domestic law determines whether a PE exists, double tax treaties play a decisive role in allocating taxing rights between Spain and the company’s home jurisdiction. 

Understanding how treaty protection interacts with domestic law is essential to managing PE risk.

1. Role of Tax Treaties in Permanent Establishment Analysis

Tax treaties determine:

• Whether a PE threshold is met under treaty-specific definitions
• Which country has primary taxing rights over business profits
• How double taxation is eliminated

Even if Spanish domestic law identifies a PE, a tax treaty may override domestic taxation if treaty PE criteria are not satisfied. This is often referred to as “treaty override in favor of the taxpayer.” 

In practice:

• Domestic law establishes initial tax liability.
• Treaty provisions may limit Spain’s ability to tax if the treaty threshold is higher.

However, treaty protection applies only where the foreign company qualifies as a resident of the treaty partner country and can document that status appropriately.

2. Foreign Permanent Establishment Exemption and Double Taxation Relief

If Spain has taxing rights over profits attributable to a PE, the company’s home country must provide relief to prevent double taxation.

This relief generally takes one of two forms under treaties:

• Tax Credit Method: The home country taxes worldwide income but grants a credit for Spanish corporate tax paid on the PE profits.
• Exemption Method (Foreign Permanent Establishment Exemption): The home country exempts profits attributable to the PE from domestic taxation, avoiding double taxation entirely.

The applicable method depends on the specific bilateral treaty and the home country’s domestic law.

3. Mutual Agreement Procedure (MAP)

Where double taxation arises despite treaty protections, companies may seek resolution through the Mutual Agreement Procedure (MAP). It allows competent authorities of both countries to negotiate to eliminate double taxation.

Permanent Establishment Certificate in Spain

There is no permanent establishment certificate in Spain. Instead, PE status is established through tax registration and ongoing compliance with the AEAT.

Below is how PE recognition works in practice.

Tax Authority Registration Requirement

Once a PE is deemed to exist under domestic law, the foreign entity must register with AEAT.

This typically includes:

• Filing Form 036 (census declaration for tax registration)
• Declaring the start of activities in Spain
• Registering for applicable taxes

Failure to register timely increases PE risk, particularly if operations have already commenced.

Obtaining a Spanish Tax Identification Number (NIF)

A foreign PE must obtain a Spanish Tax Identification Number (Número de Identificación Fiscal, NIF).

This NIF:

• Identifies the PE for corporate income tax purposes
• Is required for VAT registration
• Is necessary for payroll withholding and invoicing compliance

The NIF functions as practical confirmation that the PE is formally registered for tax purposes.

Appointment of a Local Representative

Non-resident entities operating through a PE may be required to appoint a tax representative in Spain in certain circumstances, particularly where no EU/EEA residence applies. This representative acts as a liaison with Spanish tax authorities.

Permanent Establishment Checklist for Foreign Companies

Before expanding into Spain, foreign businesses should apply a structured permanent establishment checklist to identify exposure. Below is a practical compliance-focused checklist.

1. Assess Physical Presence in Spain

Determine whether the company has a fixed place of business in Spain, including:

• Office space
• Warehousing facilities
• Project sites
• Long-term co-working arrangements

Evaluate whether the location is at the company’s disposal and used for core business functions. 

2. Review Employee Authority

Analyze whether Spain-based personnel:

• Negotiate material contract terms
• Habitually secure orders
• Have authority to conclude contracts

Dependent agent activity significantly increases PE risk, even without a formal branch.

3. Analyze Contract Practices

Review how contracts are finalized in practice:

• Are contracts signed in Spain?
• Is head office approval merely formal?
• Are local employees effectively binding the company?

Substance-over-form analysis applies under Spanish tax practice. Functional authority may create a foreign PE even if contracts are technically executed abroad.

4. Check Treaty Thresholds

If the foreign company is resident in a treaty jurisdiction, verify:

• Construction duration thresholds
• Service PE clauses (if included in the treaty)
• Specific exclusions for preparatory or auxiliary activities

Treaty analysis determines whether a foreign PE exemption may apply to limit Spain’s taxing rights.

Compliance Obligations After Creating a PE in Spain

Once a PE is created, the foreign company moves from a market-entry phase into a full tax compliance environment. A PE is treated, for many operational purposes, similarly to a resident company with respect to accounting, filing, and reporting obligations. The administrative burden can be substantial and requires structured internal controls.

Below are the key compliance obligations triggered after a foreign PE is formed.

1. Tax Registration With AEAT

The first operational requirement is formal registration with the AEAT.

This includes:

• Filing Form 036 (census declaration)
• Obtaining an NIF
• Registering for applicable taxes

Although Spain does not issue a standalone PE certificate, registration confirms recognition of PE status for tax purposes.

2. Periodic Corporate Income Tax Payments

A PE is subject to tax in Spain under the Non-Resident Income Tax regime.

Obligations include:

• Filing periodic installment payments (if applicable)
• Filing the annual corporate income tax return
• Paying corporate income tax on profits attributable to the PE

Taxation applies exclusively to profits attributable to Spanish activities under arm’s length principles.

3. VAT Registration and Periodic VAT Returns

If the PE conducts taxable transactions in Spain, VAT registration is required.

Ongoing VAT compliance may include:

• Quarterly or monthly VAT returns
• Annual VAT summaries
• Electronic invoicing compliance
• Real-time reporting under Spain’s Immediate Supply of Information (SII) system for qualifying taxpayers

VAT obligations are independent of corporate income tax and often increase overall PE risk if not properly managed.

4. Bookkeeping and Accounting Standards

A foreign PE must maintain accounting records in accordance with Spanish accounting principles sufficient to determine profits attributable to the PE.

This typically requires:

• Separate income and expense tracking
• Documentation of intercompany transactions
• Retention of accounting records for statutory periods

Failure to maintain adequate records can lead to estimated tax assessments by authorities.

How to Avoid Unintended Permanent Establishment in Spain?

Avoiding an unintended PE in Spain requires careful structuring and ongoing compliance. The AEAT applies both domestic corporate tax rules and applicable tax treaties.

Below are practical, compliance-focused strategies tailored for Spain.

1. Use Truly Independent Distributors

Operating in Spain through a genuinely independent distributor can significantly reduce PE exposure.

To qualify as independent under Spanish and treaty standards, the distributor should:

• Operate in its own name and for its own account
• Bear entrepreneurial and inventory risk
• Serve multiple clients (not economically dependent)
• Set its own commercial strategy

If the distributor acts exclusively or almost exclusively for the foreign company, or if pricing and commercial terms are tightly controlled from abroad, the Spanish tax authorities may reclassify the arrangement as a dependent agent PE.

2. Restrict Contract Conclusion Authority

Under Spanish Corporate Income Tax Law, a PE may arise where a person in Spain:

• Habitually concludes contracts on behalf of the foreign company, or
• Plays the principal role leading to the conclusion of contracts

To reduce risk:

• Ensure contracts are formally approved and signed outside Spain
• Centralize final pricing and negotiation authority at headquarters
• Avoid granting Spanish-based staff power of attorney

Since Spain follows post-BEPS standards, even if contracts are signed abroad, a PE can arise if Spanish personnel effectively finalize deals.

3. Carefully Manage Remote Work and Home Offices

Spain has seen increased scrutiny of remote work arrangements.

A home office may create PE risk if:

• It is used continuously and exclusively for business
• The company reimburses rent or utilities
• The employee performs core revenue-generating functions

To mitigate exposure:

• Do not designate the home as an official company office
• Avoid listing Spanish home addresses on websites or invoices
• Avoid storing inventory or company-owned equipment permanently at the location

This is particularly important for tech, SaaS, and venture-backed companies expanding into Spain without formal incorporation.

4. Avoid Long-Term Construction or Installation Projects

Under most Spanish tax treaties, construction or installation projects create a PE if they exceed a specified duration.

To manage this:

• Track project timelines precisely
• Monitor subcontractor presence
• Document start and completion dates

Spanish authorities may aggregate connected projects when assessing duration thresholds.

Penalties for Non-Compliance

Failing to properly assess and register a PE can expose foreign companies to significant financial and operational consequences. Below is a structured overview of potential exposure.

• Retroactive Corporate Income Tax Assessments: If the Spanish tax authority determines that a foreign PE existed but was not declared, it may:
  • Assess corporate income tax retroactively on profits attributable to the PE
  • Apply Spain’s standard corporate income tax rate
  • Recalculate profits using arm’s-length principles
• Late Payment Interest: Interest accrues automatically on unpaid taxes. Spain’s statutory late-payment interest rate is set annually by law. Interest applies from the original due date until payment is made. Interest is not discretionary and applies even if the PE arose unintentionally.
• Administrative Penalties: Administrative fines may apply if the failure to declare a PE in Spain is classified as a tax infringement. The severity depends on negligence, concealment, or repeated non-compliance.
• Transfer Pricing Adjustments: If a PE is recognized, the Spanish tax authority may:
  • Reattribute profits under OECD-aligned arm’s-length principles
  • Challenge intercompany pricing
  • Require contemporaneous transfer pricing documentation

When to Incorporate Instead of Operating Through a PE in Spain?

For many foreign companies entering Spain, operating through a branch or undeclared activity may initially appear simpler than forming a subsidiary. However, as operations expand, incorporation often becomes the clearer and more scalable compliance path.

Below is a structured comparison relevant to companies evaluating long-term expansion in Spain.

FAQs

1. What activities create a permanent establishment in Spain?

A Spain permanent establishment may arise where a foreign company has:

• A fixed place of business (office, branch, factory, warehouse)
• A dependent agent habitually concluding contracts
• A construction or installation project exceeding treaty thresholds
• A place where core business activity is carried out

2. Can a single employee create a permanent establishment in Spain?

Yes, potentially. A PE may arise if a single employee in Spain:

• Habitually concludes contracts, or
• Plays the principal role leading to contract conclusion, or
• Uses premises at the disposal of the foreign company

3. Does storing inventory in a third-party warehouse create a permanent establishment in Spain?

It depends on the level of control. Storage alone may not create a PE if it is purely preparatory or auxiliary. However, if inventory is regularly used to fulfill customer contracts or the warehouse is effectively at the disposal of the foreign company, permanent establishment risk in Spain increases.

4. How long can a foreign company operate in Spain before triggering permanent establishment status?

There is no universal time threshold for all activities. For construction or installation projects, tax treaties commonly apply 6- or 12-month thresholds. For fixed places of business, permanence depends on facts and circumstances rather than a strict timeline.

5. Is a subsidiary safer than operating through a permanent establishment in Spain?

From a compliance certainty perspective, often yes.

A subsidiary:

• Is a separate legal entity
• Limits liability exposure
• Provides clearer corporate tax positioning

6. Can independent contractors create permanent establishment risk in Spain?

Generally, independent contractors acting in the ordinary course of their business do not create a PE. However, if the contractor is economically dependent or habitually concludes contracts on behalf of the foreign company, Spanish authorities may reclassify them as a dependent agent.

7. What records must be maintained for permanent establishment tax compliance in Spain?

Companies with a PE must maintain:

• Accounting records consistent with Spanish standards
• Profit attribution documentation
• Transfer pricing documentation (Article 18, CIT Law)
• VAT records, where applicable
• Payroll and withholding documentation

8. How do tax authorities in Spain detect unregistered permanent establishments?

The Agencia Tributaria may detect undeclared PEs through:

• VAT registrations
• Payroll or social security records
• Information exchange under EU and OECD frameworks
• Customer audits
• Transfer pricing reviews

9. Can digital businesses or SaaS companies create a permanent establishment without a physical office in Spain?

Yes, in certain cases. While Spain does not currently apply a standalone digital PE concept outside treaty frameworks, a PE may arise if:

• Spanish-based employees negotiate contracts
• Home offices are at the company’s disposal
• Core revenue-generating functions occur in Spain

10. What happens if a permanent establishment is identified retroactively in Spain?

If authorities identify a PE retrospectively, they may:

• Assess back corporate income tax
• Impose interest
• Apply penalties
• Reallocate profits under transfer pricing rules

11. How does a permanent establishment in Spain impact global profit allocation and transfer pricing policies?

Once a PE exists, profits must be attributed using arm’s-length principles consistent with OECD guidance.

This affects:

• Intercompany pricing models
• Cost allocation structures
• Centralized IP ownership arrangements
• Global effective tax rate modeling

12. Can cross-border intercompany services trigger permanent establishment exposure in Spain?

Yes, depending on substance. If employees providing services are physically present in Spain for extended periods or habitually perform core business functions, this may create a service-based PE under treaty provisions.

13. How does permanent establishment status in Spain affect tax treaty benefits and withholding tax relief?

If a PE exists, treaty provisions may:

• Allocate taxing rights to Spain
• Reduce or eliminate double taxation through tax credits or exemptions
• Affect withholding tax treatment on payments connected to the PE

14. What restructuring options are available if an international business unintentionally creates a permanent establishment in Spain?

Options may include:

• Voluntary registration and regularization
• Conversion into a registered branch
• Incorporation of a Spanish subsidiary
• Restructuring contract authority
• Revising intercompany pricing
