The term "U.S. person" is a critical classification in international tax law and financial regulation, significantly impacting an individual's or entity's compliance obligations, particularly regarding taxation and securities offerings. Generally, a U.S. person encompasses more than just a U.S. citizen; it includes individuals who meet certain residency tests and various domestic entities. Understanding this definition is essential for navigating the complexities of global finance and avoiding potential penalties.
What Is US Person?
A "U.S. person" is a legal and regulatory classification used across various U.S. statutes, primarily in international tax law and financial regulation, to define individuals and entities subject to U.S. jurisdiction. This designation is broader than simply holding U.S. Citizenship and plays a pivotal role in determining tax obligations, reporting requirements, and the applicability of U.S. Securities laws. The specific definition of a U.S. person can vary slightly depending on the context, such as for Internal Revenue Service (IRS) Taxation purposes or Securities and Exchange Commission (SEC) regulations like Regulation S.
History and Origin
The concept of a "U.S. person" has evolved with the increasing globalization of financial markets and the need for the U.S. government to ensure compliance with its laws by individuals and entities with a connection to the United States. For tax purposes, the U.S. has historically employed a citizenship-based taxation system, meaning U.S. citizens are subject to U.S. tax on their worldwide income regardless of where they reside49. This approach dates back to the Civil War, when Congress passed a tax on U.S.-based income by "any citizen of the United States residing abroad" to discourage individuals from avoiding civic duties during a national crisis48.
In recent decades, the definition gained heightened prominence with the enactment of legislation like the Foreign Account Tax Compliance Act (FATCA) in 2010. FATCA was designed to target non-compliance by U.S. taxpayers using foreign accounts, requiring foreign financial institutions to report information about financial accounts held by U.S. taxpayers or entities in which U.S. taxpayers hold a substantial ownership interest to the IRS47. This dramatically expanded the reach and practical implications of being classified as a U.S. person. Similarly, in securities law, definitions of "U.S. person" are crucial for determining when foreign offerings need to comply with U.S. registration requirements, as outlined in rules like Regulation S.
Key Takeaways

- The definition extends beyond U.S. citizenship to include Resident Aliens meeting specific tests, as well as domestic partnerships, corporations, estates, and certain trusts46.
- Classification as a U.S. person often triggers worldwide income tax liability and reporting requirements to the IRS45.
- For securities law, being a U.S. person determines the applicability of U.S. registration rules for offerings and sales.
- The concept is fundamental to international tax Compliance and financial transparency efforts.
Interpreting the US Person
Interpreting the "U.S. person" classification requires careful consideration of the specific legal context—whether it's for tax purposes, securities regulations, or other areas of law. For individuals, the IRS defines a U.S. person as a U.S. citizen or a Resident Alien. 44A resident alien is generally someone who holds a Green Card or meets the substantial presence test, which counts days spent in the U.S. over a three-year period. 43This broad definition means that even individuals who are not U.S. citizens can be considered U.S. persons for tax purposes based on their physical presence or immigration status.
For entities, domestic partnerships and corporations are generally considered U.S. persons. Trusts and estates also fall under this classification if certain conditions are met, such as primary court supervision in the U.S. or control by U.S. persons. 42The interpretation directly dictates the scope of U.S. Jurisdiction over financial activities and assets, compelling disclosure and adherence to U.S. laws regardless of where the income is earned or where assets are held.
Hypothetical Example
Consider an individual, Maria, a citizen of Spain, who accepts a job offer in New York City. She arrives in the U.S. on January 1, 2024, and intends to live and work there for several years. For tax purposes, Maria would be considered a "U.S. person" because she meets the "green card test" if she obtains a lawful permanent resident (Green Card) status, or she will likely meet the "substantial presence test" during her time in the U.S..
41
Under the substantial presence test, Maria would be a U.S. person for the 2024 tax year if she is present in the U.S. for at least 31 days in 2024, and 183 days over the three-year period that includes 2024, 2023, and 2022 (counting all days in 2024, 1/3 of days in 2023, and 1/6 of days in 2022). 40Assuming she remains in the U.S. throughout 2024, she will easily exceed this threshold. As a U.S. person, Maria will be required to report her worldwide income to the IRS, not just her U.S.-sourced income, and comply with all applicable U.S. Taxation laws. This includes income from investments held in Spain or any other country.
Practical Applications
The classification of a "U.S. person" has significant practical applications across various financial and legal domains:
- Tax Compliance: U.S. persons are generally subject to U.S. income tax on their worldwide income, regardless of their country of Residency. This requires reporting all income, including that earned from foreign sources, and potentially filing additional forms like Form 8938 (Statement of Specified Foreign Financial Assets) or FinCEN Form 114 (Report of Foreign Bank and Financial Accounts, or FBAR). 38, 39The Foreign Account Tax Compliance Act (FATCA) significantly impacts Financial Institutions globally, compelling them to identify and report U.S. person account holders to the IRS, or face penalties.
37* Securities Offerings: Under U.S. securities law, particularly Regulation S, the definition of a U.S. person determines whether an offering of securities must be registered with the SEC. Transactions made to non-U.S. persons outside the U.S. may be exempt from registration, while offerings to U.S. persons generally require registration unless another exemption applies. 36This is crucial for international capital markets and cross-border transactions. The SEC provides detailed guidance on the definition of a "U.S. person" in the context of Regulation S to ensure compliance in offshore offerings.
35* Wealth Management and Estate Planning: For individuals with global assets, identifying as a U.S. person directly influences their Wealth Management and Estate Planning strategies. This status impacts how foreign assets are held, transferred, and taxed, necessitating specialized advice to navigate complex international tax treaties and reporting requirements.

Limitations and Criticisms
While the "U.S. person" classification is fundamental to the U.S. regulatory framework, it faces several limitations and criticisms, particularly concerning its broad application in tax law. The primary criticism centers on citizenship-based taxation, which requires U.S. citizens and Green Card holders to report and potentially pay U.S. taxes on their worldwide income, even if they live permanently abroad and pay taxes in another country. 33This dual taxation burden, although mitigated by mechanisms like the Foreign Earned Income Exclusion and foreign tax credits, can lead to significant financial and administrative complexities for U.S. persons residing overseas.
32
Critics argue that this system places an unfair burden on expatriates, often necessitating costly international tax advice and compliance efforts. The complexities can even lead some U.S. citizens to consider Expatriation to sever their tax ties with the U.S., a decision that itself involves substantial costs and implications. 31The FATCA legislation, while aimed at combating tax evasion, has also drawn criticism from foreign Financial Institutions due to the administrative burden and costs associated with identifying and reporting U.S. person accounts. Some financial institutions have opted to refuse services to U.S. persons due to the compliance complexities.
US Person vs. Resident Alien
While often overlapping, "U.S. person" and "Resident Alien" are distinct classifications, with the latter being a subset of the former primarily for tax purposes.
