U.S. Tax Services for Foreign-Owned Businesses
Navigate U.S. tax complexity with clarity, structure, and compliance support when doing business in the U.S.
If your organization is expanding into the United States or otherwise doing business in the U.S., you’re entering a complex and highly regulated tax environment. Understanding how your U.S. activities will be taxed often requires careful analysis of federal tax rules, state tax exposure, treaty provisions, and ongoing compliance requirements.
If you’re setting up a U.S. subsidiary, operating through a branch, or entering the market through distribution or service arrangements, understanding the tax implications of doing business in the U.S. is essential to knowing when U.S. tax returns are required and how your income will be treated.
RKL’s Inbound International Tax Services Team helps you evaluate your U.S. tax exposure, structure your operations thoughtfully, and stay compliant with federal and state tax requirements as you grow in the U.S. As your U.S. presence takes shape, we can also help address related employee compliance and operational needs through our Virtual Workforce Strategies Team, offering you coordinated support beyond tax as you launch and expand.

Frequently Asked Questions
Does my foreign company automatically owe U.S. tax if we do business in the United States?
Not necessarily. A foreign-owned company is not automatically subject to U.S. income tax just because it has U.S. customers or activity. Tax exposure depends on factors such as the type of income earned, where services are performed, whether the company has a U.S. trade or business and whether an applicable tax treaty limits taxation.
What is a permanent establishment, and why does it matter?
A permanent establishment, or PE, is a concept found in many U.S. income tax treaties that can determine whether the United States has the right to tax a foreign business’s profits. In general, a PE may exist if the company has a fixed place of business in the U.S. or a dependent agent with authority to conclude contracts. Because treaty definitions vary, PE analysis is highly fact-specific.
What is Effectively Connected Income (ECI)?
Effectively Connected Income, or ECI, is income that is connected to a U.S. trade or business. If a foreign corporation has ECI, it may be required to file a U.S. corporate tax return, even if little or no tax is due. Determining ECI often involves reviewing where contracts are negotiated, where services are performed, and whether personnel or agents are operating in the United States.
Do we need a U.S. legal entity to operate in the United States?
Not always. Some foreign businesses operate through a branch, while others form a U.S. subsidiary or limited liability company. Each structure has different tax, compliance, and legal implications. The right choice depends on factors such as liability protection, withholding exposure, state tax obligations, and the business’s plans for reinvesting or repatriating profits.
Can our U.S. activities create state tax obligations even if a treaty protects us from federal tax?
Yes. State tax rules often do not follow federal treaty protections. A foreign-owned company may still have state income tax, franchise tax, sales tax, or payroll tax obligations based on employees, contractors, inventory, revenue thresholds, or other state nexus rules. This is one reason state and federal tax analysis should be coordinated.
Are payments from a U.S. business to a foreign parent subject to withholding tax?
They can be. Dividends, interest, royalties, and certain other U.S.-source payments may be subject to U.S. withholding tax, often at a 30% statutory rate unless reduced by treaty. To claim treaty benefits, the foreign recipient generally must provide proper documentation, such as the applicable IRS Form W-8.
What ongoing U.S. tax filings might a foreign-owned company need to make?
Ongoing requirements may include federal income tax returns, state income or franchise tax filings, sales tax returns, payroll tax filings, and international information reporting such as Form 5472 (Related Party Disclosures). Filing obligations depend on the company’s structure and activities, and penalties for missed filings can be significant even when no tax is due.
Navigating U.S. tax requirements as a foreign-owned company can be complex, especially when operating across borders and managing evolving reporting obligations.
