First, something simple: the LLC is transparent
A single-member LLC owned by a non-US person is, in the eyes of the IRS, a disregarded entity. By default it pays no income tax in its own name. The profits "pass through" to you. And in Wyoming, the state ninety-nine percent of non-residents pick, there is no state income tax either.
So the real question is never "does the LLC pay tax?". The real question is: where are you taxed on those profits? That is where the three conditions of the 0% come from.
Condition 1: you are not a US tax resident
The zero on the American side assumes that you are not yourself a US tax resident. That means no green card, and no substantial physical presence in the United States over the year. If you spend enough days on US soil, the IRS treats you as a US tax resident, and at that point your worldwide income becomes taxable in the United States, LLC or no LLC.
Condition 2: your LLC is not "engaged in trade or business in the US"
This is the ETBUS test, and it is the part most videos skip. In practice: no office in the US, no employees or dependent agents on US soil, and the substance of the work is not physically performed in the country.
Selling your service or your product from abroad to clients who happen to be American is generally not ETBUS. Flying to the US to consult on site, or hiring an American employee, can be. When ETBUS is triggered, the income linked to that US activity becomes taxable in the US, with a personal filing to match.
Independent from ETBUS, some US-source income is taxed at source even with no US activity at all: dividends from US stocks, rent from US real estate, certain royalties. If your revenue comes from services delivered from abroad, you are generally outside that scope. If it comes from assets located in the United States, the 0% does not hold.
Condition 3, the one everyone forgets: where you actually live
Because the profits pass through to you, in the end your country of tax residence decides. The 0% is only real if you are resident in a country that does not tax that income: a territorial system (Paraguay, Panama), or a country with no personal income tax (the United Arab Emirates, a few others).
If you are still a tax resident of France, Germany, Belgium, Canada or any worldwide-taxation country, your American 0% turns back into tax at home. The LLC does not erase your residency. Trying to hide the profits behind it is not optimization, it is fraud, and it is detectable: banks report, and tax authorities exchange data across borders more every year. This is the condition that makes or breaks the 0% for the vast majority of people.
Some countries do not even see your LLC as transparent. France, for instance, may treat it as an opaque foreign company, with the risk of a double layer of taxation. In other words, even the direction of the pass-through depends on your country. One more reason to check your own case rather than trust a video selling a dream.
The real combination: territorial residency + US LLC
The zero that stacks on both sides only happens in one scenario. You live in a country with territorial taxation or no income tax, where foreign income is left alone by the local system. The US LLC is fiscally transparent. The combined result is a legally clean zero. Not a trick: a structure that has to line up on both ends. It is the setup our founder runs himself from Paraguay.
Wondering whether a US LLC even makes sense in your case, before the 0% question? We answer it without sugar-coating here: Why open a US LLC as a non-resident.
The trap: 0% tax is not 0 obligations
This is the most important point if you want to avoid a very expensive mistake. Even at zero tax, you are not at zero paperwork. A foreign-owned single-member LLC must file an information return every year: Form 5472, attached to a pro forma Form 1120.
If you forget it, the penalty starts at $25,000 per year. And do not assume the United States does not apply these penalties: it does. "No tax" and "nothing to do" are two completely different things, and that confusion is what costs the most.
On top of that, depending on your case: the annual report of the state where the LLC is registered, and the registered agent to maintain. On the beneficial ownership report (BOI), whose rules changed in 2025, we have a dedicated page: BOI reporting for a non-resident LLC.
Don't want to handle Form 5472 yourself?
We take care of your annual IRS filings, Form 5472 and pro forma 1120 included, for $297 per year.
Where to start, in the right order
The process is simple when taken in the right direction. First, you settle your tax residency. Then you look at the nature and source of your income. And only then do you set up your structure. In that order, never the reverse.
There are exceptions, but overall this is the order that avoids undoing a badly calibrated setup six months later. The engineering is not in the LLC. It is in the residency behind it.
If the residency question is still open, start there: our residency guides by country cover Paraguay, Panama and the other destinations of the Americas, with the real procedures and the tax rules of each.
Want it done for you?
Wyoming formation, EIN, Operating Agreement, registered agent and your first-year IRS filings, handled by us. And if you want to make the zero real, residency in Paraguay or Panama plus the LLC, end to end.
Frequently asked questions
Does a US LLC really pay 0% tax for a non-resident?
Not automatically. It is transparent: the profits pass through to you. The real 0% depends on the three conditions above. If one is missing (US tax residency, ETBUS, or a country of residence that taxes the income), the 0% disappears.
I live in France or Germany. Is my US LLC tax-free?
No. The profits pass through to you, and your country of residence decides. As a French or German tax resident you are taxed at home, with or without an LLC. The LLC does not create a tax residency, does not move it, and does not make it disappear. The benefit there is operational, not fiscal.
Does 0% tax mean nothing to file?
No, and that is the main trap. Even with no tax due, the LLC must file Form 5472 with a pro forma 1120 every year. Failing to file triggers a penalty starting at $25,000, actually applied.
How do I know whether my activity is "engaged in trade or business in the US"?
The classic signals are a US office, a US employee or dependent agent, inventory in the US, or performing the service physically from US soil. Selling to American clients from abroad generally does not fall into that category. It is a conclusion that has to be checked case by case.
This guide explains the principle. It is informational content, not personalized tax or legal advice. Your situation depends on your country of residence and has to be checked case by case.
