Concept
The US LLC is one of the most misunderstood tools in international planning. For a non-resident of the United States, it is attractive for its combination of jurisdictional prestige, access to payment systems, and—when properly structured—the absence of federal tax. But a "tax-free American company" exists only in marketing copy: the reality is more nuanced and rests on two concepts—disregarded entity and effectively connected income.
Disregarded Entity: Tax Transparency
A single-member LLC is by default treated by the US tax authorities as a disregarded entity—a "transparent" structure that effectively does not exist for tax purposes. Income is considered to be received directly by the member. If the member is a foreign person and the company does not engage in trade or business in the United States, no federal income tax arises for the LLC: there is nothing to tax under US rules. There is no special exemption here—the US taxes non-residents only on income from US sources, and such an LLC simply does not generate a US tax base.
ECI and ETBUS: Where the Line Is Drawn
The key concepts are engaged in a US trade or business (ETBUS) and effectively connected income (ECI). As long as the company has no ECI (no dependent agent, office, warehouse, or employees in the US, and services are provided outside the country), there is no US income tax. Once real activity occurs on US territory or goods are sold with a physical presence, the income becomes ECI and is taxed at ordinary rates. The line is thin and in disputed cases requires individual analysis—especially for marketplace sales and Amazon warehouses (FBA).
Form 5472: Discipline, Not a Formality
Since 2017, a foreign-controlled single-member LLC, even as a disregarded entity, is required to file Form 5472 annually together with a pro forma Form 1120—a report of transactions with related parties. Filing is required even if there was no activity at all. The penalty for failure to file or for an incomplete form is $25,000, and another $25,000 if the delay continues for more than 90 days after IRS notification. Electronic filing is not available for such LLCs—only by mail or fax to Ogden. An EIN is required for the company to operate.
Wyoming or Delaware
Wyoming is valued for its low fees, absence of state income tax, and registry privacy—it is a workhorse for holding companies and online businesses of non-residents. Delaware is about reputation and the Court of Chancery: it is chosen when investment fundraising or deals are ahead where counterparties expect a "Delaware" company; there is an annual franchise tax here (minimum $300). For most private purposes the difference is not dramatic—what matters more is not the state, but correct tax structuring.
What LLC Does Not Eliminate
The absence of tax in the US does not mean the absence of tax altogether. LLC profits are taxed where the owner is a tax resident, and CFC (controlled foreign corporation) rules can attribute undistributed profits to the controlling person. The LLC itself falls within the scope of CRS as a financial account, and Series LLCs and holding structures require separate analysis. A US company is a Flag 4 tool (business domicile), and it only works in combination with thoughtful owner residency planning.
💡 A US LLC for a non-resident pays no federal tax only in the absence of ECI—and is still required to file Form 5472 under penalty of $25,000. "Tax-free" status in the US does not eliminate tax in the owner's country of residence or CFC rules.
