U.S.–Korea Cross-Border Tax Services for Korean Companies and Individuals

Dow & Sohn CPAs is a Los Angeles-based CPA firm providing U.S.–Korea cross-border tax services for Korean companies, U.S. subsidiaries, business owners, and individuals with tax matters involving both the United States and Korea. We help clients navigate U.S. international tax compliance, foreign ownership reporting, withholding tax, tax treaty matters, intercompany transactions, and foreign asset reporting.

OVERVIEW

NAVIGATING U.S.–KOREA CROSS-BORDER TAX

Cross-border tax issues can arise whenever a Korean company enters the U.S. market, a U.S. subsidiary conducts transactions with its Korean parent, or an individual has income, investments, or financial assets in both countries. These situations may involve U.S. federal and state income tax, international information reporting, withholding tax, tax treaties, transfer pricing, and foreign asset reporting. Dow & Sohn CPAs helps clients understand how these requirements interact and develop practical tax and compliance strategies for their U.S.–Korea cross-border activities.

OUR SERVICES

FOREIGN-OWNED U.S. BUSINESSES

We support U.S. federal and state tax compliance and international information reporting for U.S. companies owned by Korean corporations or individuals, including foreign ownership and foreign related-party transactions. Depending on the entity structure and transactions, additional reporting such as Form 5472 may be required.

FOREIGN CORPORATIONS DOING BUSINESS IN THE U.S.

We analyze tax and filing obligations for Korean and other foreign corporations conducting business or earning income directly in the United States without a separate U.S. subsidiary, including U.S. trade or business, effectively connected income (ECI), and applicable treaty considerations.

CROSS-BORDER WITHHOLDING TAX

U.S. withholding tax analysis and compliance for cross-border payments such as interest, royalties, service fees, and other payments to foreign persons, including applicable tax treaty provisions.

TRANSFER PRICING & INTERCOMPANY TRANSACTIONS

We review arm’s-length principles and transfer pricing rules for transactions between Korean headquarters and U.S. subsidiaries, including product sales, service fees, management fees, royalties, and other intercompany transactions.

FOREIGN ASSET & INFORMATION REPORTING

Compliance support for U.S. taxpayers with foreign financial accounts, assets, gifts, inheritances, or ownership interests that may trigger U.S. international reporting requirements.

INDIVIDUAL CROSS-BORDER TAX

U.S. tax planning and compliance for individuals with income, investments, financial assets, or other tax matters involving both the United States and Korea.

U.S.–Korea Tax Treaty & Cross-Border Planning

Coordinating Tax Between the U.S. and Korea

Cross-border tax planning requires an understanding of not only U.S. tax law but also how U.S. rules interact with Korean tax and the U.S.–Korea Income Tax Treaty. Depending on the transaction, treaty provisions may affect withholding tax, business profits, interest, royalties, and other cross-border income. Dow & Sohn CPAs helps clients evaluate U.S. tax consequences while coordinating with Korean headquarters, tax advisors, and other professionals when appropriate.

Frequently Asked Questions

Q1. Does a Korean company doing business in the U.S. have to file a U.S. tax return?

It depends on the nature and extent of the company’s U.S. activities. A foreign corporation conducting a U.S. trade or business or earning certain U.S.-source income may have U.S. tax and filing obligations. The appropriate analysis depends on the company’s specific activities and applicable tax treaty provisions.

Q2. What is Form 5472 and when is it required?

Form 5472 is an information return that may be required for certain U.S. corporations and certain foreign-owned U.S. disregarded entities that have reportable transactions with foreign related parties. Filing requirements depend on the ownership structure and transactions involved.

Q3. Does a U.S. company have to withhold tax when paying its Korean parent company?

It depends on the type of payment. Interest, royalties, service fees, and other payments may be subject to different U.S. withholding rules. The U.S.–Korea Income Tax Treaty may reduce or modify withholding in certain situations if the applicable requirements are satisfied.

Q4. How should transactions between a Korean parent and its U.S. subsidiary be priced?

Related-party transactions generally should be evaluated under the arm’s-length principle. Transfer pricing considerations may apply to product sales, services, management fees, royalties, loans, and other intercompany transactions.

Q5. Do U.S. taxpayers have to report Korean bank and investment accounts?

Potentially. Depending on account balances and other factors, foreign financial accounts and assets may be subject to reporting requirements such as FBAR and Form 8938. The thresholds and rules differ between the reporting regimes.

Q6. Is money received from parents in Korea taxable in the U.S.?

Receiving a gift from a foreign person does not automatically mean that U.S. income tax is due. However, significant foreign gifts or inheritances may trigger U.S. information reporting requirements, including Form 3520 in applicable cases.

Q7. Can the U.S.–Korea tax treaty prevent double taxation?

The treaty can affect the taxation of certain types of cross-border income, but treaty treatment depends on the specific facts and applicable provisions. Foreign tax credits and other domestic tax rules may also play an important role in mitigating double taxation.
