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" lives only in marketing copy: the reality is subtler and rests on two concepts — disregarded entity and effectively connected income.
Where the Popularity Came From
The first state to pass an LLC statute was Wyoming, in 1977; a decade later the form spread to every state. The turning point was the check-the-box regime of 1997, which let an LLC choose its own tax classification — disregarded entity, partnership or corporation. For a single foreign owner, that default "transparency", combined with access to American banks and payment services, turned the LLC into the standard wrapper for online businesses and holdings. Hence the persistent myth of a "tax-free US company", which lives a life of its own in registrar advertising.
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, for tax purposes, effectively does not exist. Income is treated as received directly by the member. If the member is a foreign person and the company does not carry on a 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: An Annual Discipline
Since 2017 a foreign-controlled single-member LLC, even as a disregarded entity, must file Form 5472 each year together with a pro forma Form 1120 — a report of transactions with related parties. It must be filed even if there was no activity at all. The base penalty for a missing or incomplete form is $25,000; if the delay runs more than 90 days past an IRS notice, a further $25,000 is added for each additional 30 days, with no upper limit. E-filing is unavailable for such LLCs — only by mail or fax to Ogden; the company needs an EIN to operate and to file.
BOI and the Corporate Transparency Act
From 2024 the Corporate Transparency Act required companies to disclose their beneficial owners (BOI) to FinCEN, and initially this reached non-residents' LLCs too. But on 21 March 2025 FinCEN issued an interim final rule that redefined the term "reporting company": only entities formed under the law of a foreign country and registered to do business in the US now fall within the reporting scope. US LLCs — including those owned by foreigners — are exempt from federal BOI reporting, and FinCEN stated that it will not enforce penalties against them. As of mid-2026 FinCEN's final rule has still not been issued — the exemption operates in the form of an interim final rule, so the status is worth checking at the time of formation; in addition, some states maintain their own beneficial-ownership registries.
Wyoming or Delaware
Wyoming is prized for low fees, the absence of a state income tax and registry privacy — it is the workhorse for a non-resident's holding and online business; the annual license tax here starts at $60. Delaware is chosen for reputation and the Court of Chancery — when fundraising or deals lie ahead where counterparties expect precisely a "Delaware" company, up to a Series LLC for individual projects; for this it charges an annual franchise tax — a flat $300 due 1 June. For most private purposes the difference between the states is small: the outcome is decided by correct tax structuring and deliberate planning of the owner's residency.
Typical Scenarios
Most often a non-resident's LLC serves online services and SaaS sold to clients outside the US: there is no activity on US territory, no ECI arises, and the company owes no federal tax either. Similar logic works for consulting delivered from abroad and for a holding through which IP or stakes in foreign companies are held. Frequently the main value of such a structure is access to Stripe, PayPal and dollar accounts itself, and the tax effect is secondary. The line is crossed where physical presence appears: a warehouse, employees or inventory in the US (the classic case being Amazon FBA) move the income into the ECI category with all that follows.
What an LLC Does Not Eliminate
The absence of tax in the US does not mean the absence of tax altogether. An LLC's profit is taxed where its owner is a tax resident, and CFC rules can attribute undistributed profit to the controlling person. The LLC itself falls within the CRS perimeter as a financial account, while Series LLCs and holding structures require separate analysis — as does the question of beneficial ownership. A US company is a Flag 4 tool (business domicile) from the five flags theory, and it works only in combination with deliberate planning of the owner's residency and real economic substance.
