Does a Foreign-Owned LLC Pay US Tax?
The internet is full of "gurus" claiming that a foreign-owned US LLC pays 0% tax. While this is true for many online businesses, it is dangerously false for others. It all comes down to two IRS concepts: ETB and ECI.
Quick Answer
A foreign-owned LLC only pays US federal income tax if it is Engaged in a Trade or Business in the US (ETB), which generates Effectively Connected Income (ECI). If you have no physical presence, no US employees, and no dependent agents in the US, your LLC usually has no ECI, meaning you owe 0% US federal income tax.
Key Points for 2026
- Physical Presence is Key: Storing physical inventory in the US (like Amazon FBA) usually triggers US taxation.
- Digital Services: Selling software, consulting, or digital goods from your home country to US clients usually does not trigger US taxation.
- State Taxes: Even if you owe no federal income tax, you may still owe state sales tax depending on where your customers are located (Economic Nexus).
Understanding ETB and ECI
To owe US tax as a foreigner, two things must be true:
1. Engaged in a US Trade or Business (ETB)
You are considered ETB if you have "considerable, continuous, and regular" business activity in the United States. In the modern era, the IRS generally defines this as having a Permanent Establishment. You have a permanent establishment if you have:
- An office, factory, or retail store in the US.
- Physical inventory stored in a US warehouse.
- W-2 employees living and working in the US.
- A "Dependent Agent" in the US (someone who works exclusively for you and signs contracts for you).
2. Effectively Connected Income (ECI)
If you are ETB, then the income you generate from that US business is considered Effectively Connected Income (ECI). You must file a non-resident tax return (Form 1040-NR) and pay US income taxes (up to 37%) on that specific income.
Even if you determine you have no ETB, no ECI, and owe 0% US tax, you must still file Form 5472 every year. The IRS wants to know what you are doing, even if they aren't taxing it. Failing to file Form 5472 results in a $25,000 penalty.
Example Scenarios
Scenario A (0% US Tax): Maria lives in Spain. She owns a Wyoming LLC. She provides freelance graphic design services to clients in New York. She works entirely from her laptop in Madrid. She has no US office and no US employees. Result: No ETB, No ECI. She pays 0% US tax (but she must pay Spanish taxes on that income).
Scenario B (Owes US Tax): David lives in Australia. He owns a Delaware LLC. He buys products from China and ships them to an Amazon FBA warehouse in California, which fulfills his US orders. Result: The US warehouse creates a Permanent Establishment. He is ETB, has ECI, and must pay US federal income tax on his American profits.

- Analyze your supply chain: If you sell physical goods, speak to a US CPA about your warehouse logistics before you incorporate.
