When U.S. Activities Create Federal Income-Tax Exposure

A foreign manufacturer does not need to establish a U.S. subsidiary before U.S. federal income-tax exposure can arise. The analysis depends on what the company actually does in the United States, who performs those activities, and how revenue-producing operations are organized.

Entity Structure Is Only the Starting Point

A U.S. subsidiary is generally a separate U.S. taxpayer. Operating directly through the foreign company may instead create a U.S. trade or business, with income connected to those activities potentially subject to U.S. tax. A branch structure can also create additional tax and reporting considerations. The absence of a U.S. legal entity therefore does not, by itself, prevent a federal filing obligation.

People, Authority, and Contracts Matter

Employees, secondees, contractors, sales representatives, or other agents working in the United States can materially change the analysis. Relevant activities may include soliciting business, negotiating commercial terms, concluding contracts, providing technical support, installing or servicing products, managing customers, or exercising authority on behalf of the foreign company.

Where an applicable income-tax treaty applies, the foreign enterprise may be taxed on business profits only when its U.S. activities create a permanent establishment. That threshold is not identical to the domestic-law concept of a U.S. trade or business. A fixed place of business, sustained service activity, or a dependent agent with sufficient contracting authority may create treaty exposure, depending on the treaty and the facts.

Inventory and Services Can Shift the Position

Holding inventory in the United States, using a warehouse or distribution facility, maintaining consignment stock, or controlling fulfillment operations may contribute to a taxable presence, especially when combined with local sales or operational activity. Storage alone may receive different treatment from active distribution, customer service, repair, or order-management functions.

Services performed physically in the United States are particularly important because they can generate U.S.-source income and support a finding that the foreign company is conducting business in the country. Clinical support, training, installation, field service, management, and consulting arrangements should therefore be reviewed before personnel begin work.

A filing obligation can arise even when deductions eliminate taxable income or a treaty position is expected to prevent tax. In some cases, a protective return may be appropriate to preserve deductions and disclose the company’s position. Federal income-tax analysis must also be coordinated separately with state income, franchise, payroll, sales-tax, and corporate-registration requirements.

MDD Options can help foreign medical-device companies design a U.S. operating model that separates distribution, importing, inventory control, contracting, and support activities in a deliberate manner. Its hybrid distribution model can provide U.S. operational infrastructure without assuming that every manufacturer should immediately establish its own subsidiary or place personnel on the ground. Where tax exposure requires specialist analysis, MDD Options can map the factual operating model, identify the relevant activities and contractual relationships, and coordinate efficiently with the company’s U.S. tax and legal advisers.
