When a foreign company establishes and operates a subsidiary in Korea, two of the most significant tax risks—both of which can lead to substantial tax assessments—are transfer pricing (“TP”) and permanent establishment (“PE”) risks.

The Korean tax authorities maintain an increasingly sophisticated enforcement and data-analysis framework to identify multinational enterprises that improperly shift profits offshore through related-party pricing or conduct substantive business activities in Korea without appropriately recognizing a Korean taxable presence.

Unless a foreign-invested company understands the legal mechanisms underlying transfer pricing and PE exposure from the outset and establishes a defensible operating structure, a tax audit conducted several years later may result in significant corporate income tax assessments, penalties, and interest.

This article introduces the two principal risks that foreign companies may face when establishing subsidiaries in Korea and outlines practical strategies for mitigating them.

1. Transfer Pricing Risk

Transfer pricing rules are designed to determine whether transactions between a foreign parent company and its Korean subsidiary are conducted at arm’s length.

In other words, the Korean tax authorities examine whether the prices applied to related-party transactions differ from those that would have been agreed between independent parties and whether such pricing has resulted in profits being improperly shifted out of Korea.

Case 1) Inflated Purchase Prices and Underpriced Export Sales

A common transfer pricing issue arises where a Korean subsidiary operates as a distributor and purchases products from its foreign parent at excessively high prices.

A similar issue arises where a Korean manufacturing subsidiary sells products to its foreign parent at artificially low prices, thereby reducing the taxable profitability of the Korean entity.

The Korean tax authorities may compare the Korean subsidiary’s profitability against comparable companies operating in the same or similar industries. If the subsidiary’s profit margin is materially below an arm’s-length range, the authorities may recalculate the appropriate transfer price and assess additional Korean corporate income tax.

Case 2) Denial of Deductibility for Management and Service Fees

Management fees and intercompany service charges are among the areas most frequently scrutinized in tax audits of foreign-invested companies.

For example, a foreign parent company may invoice its Korean subsidiary for services described as “IT support,” “HR and finance advisory services,” or “brand management,” and the Korean subsidiary may deduct those payments as business expenses.

The Korean tax authorities may deny the deduction in whole or in part unless the company can adequately demonstrate the following:

① Actual provision of services:
The company should maintain concrete evidence showing that the services were actually rendered, including emails, meeting minutes, reports, deliverables, and other supporting documentation.

② Economic benefit:
The services should provide an identifiable business benefit to the Korean subsidiary, such as increased revenue, operational efficiency, or reduced costs. Expenses relating solely to shareholder activities of the foreign parent may not be deductible by the Korean subsidiary.

③ Reasonableness of the calculation methodology:
The methodology used to calculate or allocate the service fees should be commercially reasonable and supported by an appropriate cost-allocation formula or pricing methodology.

Transfer Pricing Documentation Requirements

Where the Korean subsidiary exceeds certain revenue and related-party transaction thresholds, it may be required to prepare and submit transfer pricing documentation, including a Local File and Master File, to the Korean tax authorities.

Failure to submit required documentation within the applicable deadline, or submission of materially inaccurate information, may result in administrative penalties and can increase the company’s exposure in a future tax audit.

2. Permanent Establishment Risk

A permanent establishment generally refers to a fixed place of business or other taxable presence through which a foreign enterprise carries on all or part of its business activities in Korea.

As a general principle, a Korean subsidiary is a separate Korean legal entity and does not automatically constitute a PE of its foreign parent company.

However, where the Korean subsidiary effectively carries out the business of the foreign parent or acts on behalf of the parent in substance, the Korean tax authorities may determine that the foreign parent itself has a taxable permanent establishment in Korea.

Dependent Agent Permanent Establishment

A dependent agent PE risk may arise where employees of the Korean subsidiary are formally employed by the subsidiary but, in practice, negotiate with Korean customers on behalf of the foreign parent and determine material commercial terms of transactions.

Even where the final agreement is formally signed by an executive of the foreign parent outside Korea, PE exposure may arise if the Korean personnel effectively exercise the principal role in concluding contracts or determining the material terms of those contracts.

In such circumstances, the Korean activities may be viewed as being conducted on behalf of the foreign parent rather than merely as activities of an independent Korean subsidiary.

Fixed Place PE and Expatriate Employee Issues

A separate PE risk may arise where employees or executives of the foreign parent use a dedicated space within the Korean subsidiary’s office for an extended period while performing the foreign parent’s own business activities.

For example, if foreign parent personnel regularly conduct global contract negotiations, R&D activities, regional management functions, or other core business activities from the Korean office, the relevant office space may potentially be characterized as a fixed place of business of the foreign parent.

Consequences of a PE Determination

If the Korean tax authorities determine that the foreign parent has a PE in Korea, profits attributable to that PE may become subject to Korean corporate income tax in the name of the foreign parent.

The authorities may also assess additional taxes for prior years together with applicable penalties, interest for late payment, and penalties relating to withholding tax or other reporting failures.

Depending on the scale of the business and the period involved, the resulting tax exposure can be substantial.

3. Interaction Between Transfer Pricing and PE Risks

Transfer pricing and PE issues should not be viewed in isolation. In practice, they frequently arise from the same underlying business structure.

A typical example involves a Korean subsidiary formally characterized as a low-risk distributor or marketing support service provider.

The subsidiary may report only a limited operating margin—for example, 5% to 10%—while the majority of the profits generated from the Korean market are retained by the foreign parent.

During a tax audit, however, the Korean tax authorities may discover that the Korean subsidiary was in fact performing significant sales, marketing, customer negotiation, and pricing functions in Korea.

In such a case, the authorities may take the position that:

  1. the Korean subsidiary did not receive an arm’s-length level of profit for the functions it actually performed, resulting in a transfer pricing adjustment; and
  2. the activities conducted in Korea also created a PE of the foreign parent, potentially resulting in additional Korean taxation of profits attributable to that PE.

Accordingly, the substance of the Korean subsidiary’s actual activities must remain consistent with its contractual characterization and transfer pricing model.

4. Strategies for Managing Transfer Pricing and PE Risks

Carefully Draft Intercompany Agreements

Agreements between the foreign parent and the Korean subsidiary should clearly define the subsidiary’s functions, authority, and risk profile.

Where the subsidiary is intended to operate as an independent distributor or contractual service provider, the agreement should expressly define those limitations and clarify whether the subsidiary has authority to enter into contracts on behalf of the foreign parent.

The actual conduct of the parties should also remain consistent with the contractual terms.

Maintain Comprehensive Evidence Supporting Management Fees

For management fees or other service charges paid to the foreign parent, the Korean subsidiary should maintain an organized database of supporting documentation.

This may include:

  • monthly or quarterly descriptions of services performed;
  • relevant emails and communications;
  • reports and deliverables;
  • records of personnel involved;
  • cost allocation calculations; and
  • supporting documentation for the pricing methodology.

Such documentation should be maintained on a contemporaneous basis rather than reconstructed only after a tax audit begins.

Control the Activities of Parent-Company Expatriates and Korean Subsidiary Personnel

The practical authority exercised by personnel in Korea should be carefully managed.

Business cards, email signatures, customer communications, and negotiation practices should not inaccurately imply that Korean subsidiary employees have authority to bind the foreign parent where no such authority is intended.

Similarly, where executives of the foreign parent spend significant time in Korea, their activities should be carefully reviewed to determine whether they are performing shareholder-level oversight, subsidiary management functions, or the foreign parent’s own core business activities.

Consider an Advance Pricing Agreement

Where the volume of related-party transactions is significant or the company faces material transfer pricing uncertainty, an Advance Pricing Agreement (“APA”) may provide greater tax certainty.

Through an APA, the taxpayer may reach an advance agreement with the Korean tax authorities regarding the appropriate transfer pricing methodology for specified related-party transactions.

Where appropriate, a bilateral APA (“BAPA”) involving the tax authority of the foreign parent’s jurisdiction may provide additional protection against double taxation.

A Poorly Designed Structure Becomes More Dangerous as the Business Grows

Transfer pricing and permanent establishment risks are not merely ongoing compliance matters. They should be treated as fundamental legal and tax structuring issues from the earliest stage of entering the Korean market.

If the initial business structure lacks sufficient tax and legal support, a future tax audit may result not only in substantial additional tax liabilities but also in disruption to the company’s business operations and reputational damage.

Foreign companies seeking to build sustainable operations in Korea should therefore establish a defensible transfer pricing structure, clearly allocate functions and decision-making authority between the parent and subsidiary, and maintain appropriate documentation from the outset.

Early coordination between legal and tax professionals can substantially reduce the risk of unexpected assessments and provide a more stable foundation for long-term operations in Korea.
