U.S. Market Entry - 5 Things Foreign Investors Should Know Before Investing in the U.S.

Investing in the United States can be an opportunity for foreign individuals and businesses to diversify and expand—it does come with a complex web of U.S. tax rules, compliance obligations, and strategic decisions.

Understanding the U.S. tax landscape is essential to structuring the investment and optimize returns, particularly if you are:

• Raising capital,

• Launching a U.S. subsidiary,

• Financing,

• Acquiring real estate,

• Engaging in M&A transactions, or

• Expanding business operations or investment portfolios

Here are five key things every foreign investor should know before investing in U.S. market:

1. How You Structure the Investment Matters—A Lot

The structure design to channel the U.S. investment will determine the exposure to U.S. taxes, liability, and reporting requirements. Common basic structures include:

• Direct ownership of U.S. assets, which can trigger income, estate, and gift tax exposure.

  
  

• U.S. partnerships, which pass income through to investors and require U.S. tax filings.

  
  

• U.S. corporations, which may limit personal liability and can result in two levels of taxation (corporate and shareholder levels).

  
  

• Foreign holding companies, which may offer estate tax protection and are subject to anti-abuse rules.

  
  

While U.S. Limited Liability Companies (LLCs) can offer administrative simplicity and operational flexibility, they are not universally optimal. In many cases—particularly with cross-border considerations—they may fall short of aligning with specific regulatory, tax, or business objectives.

Strategic tax planning goes beyond entity selection and common basic structures. It requires a nuanced understanding of the investor’s intent, the desired holding structure, and the interplay of home-country tax rules with U.S. regulations, and tax treaties.

Identifying the right structure to support long-term growth demands a holistic view of the investment funds or investor’s goals, risk profile, and compliance landscape. No single structure fits all, and success lies in balancing simplicity with business and strategic alignment.

2. U.S. Federal Tax Exposure Can be Broad

Foreign investors are subject to several U.S. tax regimes, including:

• Withholding tax: A 30% tax on U.S.-source passive income (e.g., dividends, interest, royalties, etc.), unless reduced by treaty.

  
  

• ECI: Non-passive income that is treated as effectively connected to a U.S. trade or business is subject to ordinary U.S. federal income tax rates—and, where applicable, state income taxes.

  
  

• FIRPTA: Gains from U.S. real estate are taxed as effectively connected income (ECI), with a 15% withholding on the gross sales price.

  
  

• Branch profits tax: Foreign corporations with U.S. branches face an additional 30% tax on repatriated earnings (or a lower treaty rate).

  
  

Proper classification of income as ECI is critical, as it triggers filing obligations and determines the applicable tax treatment for foreign investors.

Understanding the intricate rules governing cross-border investments is essential to planning effectively. These rules are often nuanced and can vary significantly based on the investor’s jurisdiction and objectives.

We can help you navigate these complexities with confidence—managing risks, aligning decisions with long-term goals, and meeting tax compliance obligations every step of the way.

3. U.S. State Taxes Can Be a Hidden Cost

Many foreign investors focus primarily on U.S. federal income tax rules and overlook state-level taxes - yet state and local taxes can affect the overall return on investment. Key considerations include:

• Income and franchise taxes imposed by many states

  
  

• Nexus rules that determine when a business is subject to state tax

  
  

• Real property taxes on U.S. real estate

  
  

• Varying apportionment and sourcing rules that affect how income is taxed across states

  
  

• State non-conformity to U.S. federal income tax provisions

  
  

Each state has its own rules (all 50 states do), and compliance is not optional.

Integrating a proactive, jurisdiction-specific state tax strategy may be essential for material jurisdictions in order to manage risks and timely identify opportunities.

4. Compliance Is Complex and Non-Negotiable

The U.S. tax system imposes extensive filing and reporting requirements on foreign investors, including:

• U.S. tax returns for ECI

• Withholding and reporting on U.S.-source income and real estate sales (e.g., Forms 8288/8288-A)

• Form 5472 for foreign-owned U.S. corporations and U.S. disregarded entities (including LLCs)

• U.S. State-specific filings, which vary by jurisdiction

  
  

Filing and reporting obligations often extend beyond the U.S. entity—in certain cases to the foreign investor as well. Depending on ownership thresholds, income types, or jurisdictional ties, multiple layers of compliance may apply.

Failure to meet these requirements can lead not only to steep financial penalties, but also to reputational risk that may hinder future investment opportunities.

A proactive approach to understanding the scope of filings, and fulfilling applicable obligations is essential for long-term success.

5. Tax Treaties and Planning Opportunities Could Work in Your Favor

Many countries have tax treaties with the U.S. that can reduce withholding tax rates, prevent double taxation, and clarify residency rules, provided treaty-eligibility requirements are met.

Strategic planning can also help:

• Optimize entity structures

• Identify certain favorable elections

• Leverage tax attributes, income recognition, and repatriation

• Manage estate tax exposure for foreign individuals
