Establishing business operations in the United States is a significant step for Asia-Pacific (APAC) companies. While the U.S. market offers scale, access to customers, and strategic growth opportunities, it also introduces a regulatory, tax, and compliance landscape that is often far more complex than many businesses anticipate.

Key decisions made at the outset (such as how the U.S. entity is structured, how it is funded, how contracts are written, and where operations are located) can have long-lasting effects on tax exposure, reporting obligations, operational flexibility, and risk management.

This FAQ provides practical guidance for APAC companies preparing to launch or expand active business operations in the United States. It addresses the most common structural, tax, and compliance questions that arise when foreign operating businesses move from selling into the U.S. market to establishing a physical and legal presence within it.

This overview is informational only and should not be relied upon as a substitute for individualized legal or tax advice.

What are the main ways APAC companies can establish an active business in the U.S.?

Most APAC groups prefer a U.S. C corporation because it provides limited liability, simpler compliance, and clearer repatriation/exit mechanics. Other common entry structures include:

• A U.S. C corporation subsidiary (most common)
• A U.S. branch of a foreign corporation (less common due to liability exposure and compliance complexity)
• A U.S. LLC taxed as a corporation or partnership
• Joint ventures with U.S. partners, taxed as a corporation or partnership
• Acquisition of an existing U.S. business

Should APAC companies operate through a U.S. subsidiary or a branch?

U.S. Subsidiary (C corporation)

• Simplifies U.S. tax compliance
• Limits liability
• Avoids Branch Profits Tax
• Easier for banking, payroll, and operations

U.S. Branch (including single-member LLC)

• Requires filing Form 1120‑F by owner; SMLLCs may also need Form 5472
• Exposes the foreign parent to Branch Profits Tax
• Harder to isolate U.S. risks
• Rarely used unless operations are very small

What is the Branch Profits Tax?

The Brand Profits Tax (BPT) applies when a foreign corporation operates through a U.S. branch. It functions similarly to a dividend withholding tax on decreases in U.S. net equity.

APAC companies generally avoid BPT by using a U.S. corporation.

Best practice: Most APAC groups operate via a U.S. C corporation.

When does a foreign business create a U.S. trade or business (USTB) or permanent establishment (PE)?

A USTB/PE may be created through:

• Hiring U.S. employees
• Maintaining an office, warehouse, or distribution center in the U.S. outside a foreign-trade zone
• Regular visits by executives/employees
• Dependent agents concluding contracts in the U.S.

Most APAC companies with active U.S. activities will create a USTB/PE.

U.S. Federal, State & Local Taxation

How are active U.S. business operations taxed at the federal level?

A U.S. corporation is subject to:

• 21% federal corporate income tax
• Potential withholding tax on payments to the foreign parent (dividends, interest, royalties, U.S.-source services)
• Transfer pricing rules on intercompany transactions

What are the state and local tax considerations for multistate operations?

Each state has separate tax rules. APAC businesses may face:

• State corporate income/franchise taxes
• Sales and use taxes
• Gross receipts taxes
• Local business (e.g. city tax, business licenses) and payroll taxes
• Secretary of State registration

Under economic nexus, companies can owe tax based solely on sales into a state, even without physical presence.

Do APAC countries have tax treaties with the U.S.?

Treaty status impacts withholding tax rates (including BPT) and PE rules.

Treaty countries: Japan, Korea, China, Thailand, Philippines
Non‑treaty countries: Hong Kong, Singapore, Taiwan, Malaysia, Indonesia, Vietnam

What transfer pricing rules apply to APAC parent–subsidiary structures?

Intercompany pricing must be arm’s length (what a third party would pay for a comparable good/service), including:

• Royalties
• Management/service fees
• Sales of goods (buy/sell models)
• Intercompany loans/guarantees

Transfer pricing documentation is recommended to avoid penalties.

Structuring, Exit & Entity Considerations

What entity structures are commonly used?

Common structure: APAC Parent → U.S. Operating C Corporation

Holding companies may be used when:

• Multiple U.S. subsidiaries exist
• Additional legal or operational separation is needed

Holding companies in non‑treaty countries (HK, SG, BVI, Cayman) require careful U.S. coordination.

Consideration should be given to the overall contract and product flow between parent and ultimate customer will work. Many choose to begin U.S. operations as limited-service model where the U.S. subsidiary provides services to the ASPAC parent and ASPAC parent contracts directly with customers. As U.S. operations grow, the model may shift from the U.S. subsidiary service provider to a full principal on customer and supplier contracts.

How should the U.S. subsidiary be funded: equity or debt?

Funding should align with overall group financing strategy, and many companies use a mix of both.

• Equity funding: dividend distribution may trigger local tax; administratively simpler; no interest deductions.

• Debt funding: no U.S. or local tax upon repayment of principal, requires arm’s length interest charge, allows interest deductions (subject to limitation) but may trigger U.S. withholding tax.

How can profits be repatriated to the APAC parent?

Common methods:

• Dividends
• Management/service fees
• Royalties
• Interest

Each has different withholding/treaty implications and should be documented with intercompany agreements and transfer pricing studies where applicable.

What tax issues apply when selling or exiting the U.S. business?

• Nonresident stock sales may avoid U.S. tax unless FIRPTA applies
• FIRPTA affects real‑estate‑heavy businesses
• Asset vs. stock sale outcomes differ
• Sales of interest in U.S. partnerships generating ECI are subject to U.S. tax

Reporting & Compliance Requirements

What filings are required for a foreign‑owned U.S. corporation?

• Form 1120 (corporate income tax return)
• Form 5472 for foreign-related transactions or foreign‑owned SMLLCs
• State income/franchise taxes, including gross receipts tax
• Sales tax filings and nexus monitoring
• Payroll tax registrations and filings
• Transfer pricing documentation (recommended)
• FinCEN Beneficial Ownership Information (BOI) reporting may apply for foreign companies doing business in the U.S.

• W‑8BEN‑E / W‑8BEN withholding documentation

What other operational considerations arise beyond income tax?

• Applicable licenses and registrations: Depending on industry and state, may include sales tax permits, import/export registrations, state business licenses, professional license
• Accounting and Audit Standards: U.S. GAAP is common but not required for private companies. No statutory audit requirement: Group consolidation depends on APAC parent rules
• Employment and Payroll considerations: Federal and state payroll withholding; Workers’ compensation; Unemployment insurance; Labor law compliance; Employee handbooks and HR policies

• Immigration considerations for APAC executives: Common visas (handled by immigration counsel): L‑1A / L‑1B; E‑2 (Japan and Korea eligible); H‑1B; O‑1

Successfully operating in the United States requires more than forming a legal entity. It requires coordination across tax, legal, accounting, payroll, regulatory, and operational functions from the very beginning.

With proactive planning, APAC companies can avoid common missteps, reduce unnecessary compliance burdens, and establish a structure that supports long-term growth, efficient repatriation of profits, and flexibility as U.S. operations evolve. This includes thoughtful pre-entry tax planning and structuring, proper federal, state, and sales/use tax registrations, and establishing compliance processes for Forms 1120, 5472, and required multistate filings.
