Where a business involves the United States in some form, a key question is whether that activity gives rise to U.S. tax exposure. This is often approached in terms of whether a company is “doing business” in the United States. In practice, the answer depends on the nature of the activity, how it is carried out, and how it is structured.
General framework
U.S. tax exposure is generally linked to the presence of a trade or business in the United States, or to specific types of U.S.-source income.
For foreign-owned structures, this requires consideration of whether activities carried out in or connected to the United States are sufficient to create a taxable presence. This is not determined by a single factor, but by the overall pattern of activity.
Nature of activities
The type of activity is a primary consideration.
Activities such as providing services in the United States, maintaining inventory, or operating through personnel or representatives located in the country may give rise to U.S. tax exposure.
By contrast, activities conducted entirely outside the United States, even where customers are located in the United States, may not in themselves create a taxable presence.
The distinction depends on where the activity takes place and how it is performed.
Physical and operational presence
Physical presence is often an indicator, but not the only one.
Having employees, agents, or other representatives in the United States, or maintaining facilities such as offices or warehouses, may indicate that business is being conducted within the country.
In some cases, even limited presence — for example, individuals regularly acting on behalf of the business in the United States — may be sufficient to create exposure, depending on the circumstances.
Role of structure
How the business is structured plays an important role in determining whether U.S. activity results in tax exposure.
For example, the use of a U.S. entity, the allocation of functions between entities, and the way in which activities are carried out can all influence the analysis.
A structure in which activities are formally outside the United States but are effectively carried out within it may not achieve the intended result. Conversely, a properly aligned structure may limit exposure where activities are genuinely conducted outside the country.
Transactions and revenue flows
The way in which revenue is generated and transactions are structured also affects the outcome.
Where income is connected to activities carried out in the United States, it may be treated as effectively connected with a U.S. trade or business. This can result in U.S. tax obligations, even for foreign-owned entities.
Understanding how revenue flows through the structure, and how it relates to underlying activities, is therefore an important part of the analysis.
Treaty considerations
In some cases, tax treaties between the United States and other countries may affect the outcome.
Treaties may limit taxation where certain thresholds are not met, such as the presence of a permanent establishment. However, the application of treaty provisions depends on the specific facts and on how the structure is implemented in practice.
Treaty protection is not automatic and must be considered as part of the overall framework.
Practical approach
Determining whether U.S. activity creates tax exposure requires a practical assessment of how the business operates.
This involves:
The objective is to ensure that the structure reflects the actual operation of the business, and that any exposure is identified and addressed appropriately.
Conclusion
U.S. tax exposure does not arise solely from the presence of U.S. customers or connections to the U.S. market. It depends on the nature of the activities, how they are carried out, and how they are structured.
A clear understanding of these factors is necessary to determine whether exposure arises and how it should be addressed within the broader framework of the business.

Determining whether U.S. activity creates tax exposure requires a practical assessment of how the business operates.
This involves:
- identifying where activities take place
- understanding who performs those activities
- reviewing how functions are allocated across entities
- considering how revenue is generated and recognized
The objective is to ensure that the structure reflects the actual operation of the business, and that any exposure is identified and addressed appropriately.
