"Disregarded entity" is the name the IRS gives to a business with one owner that it does not treat as a separate taxpayer for income tax. Most single-member LLCs are disregarded entities. You do not apply for this, and you do not file anything to get it. It is what happens if you do nothing.
The name causes a specific problem. People read "disregarded" and conclude that the company does not exist for federal tax at all. The regulation does not say that. It says the company is disregarded as an entity separate from its owner, and the regulation then lists purposes where the company is not disregarded: employment taxes, certain excise taxes, and one information return.
For a founder who lives outside the United States, the second half of that sentence matters more than the first. The exception that applies to you is the one that carries the largest penalty in this whole guide.
What the regulation actually says
The rule lives in 26 CFR § 301.7701-2(c)(2)(i). The text is short:
"a business entity that has a single owner and is not a corporation under paragraph (b) of this section is disregarded as an entity separate from its owner."
So there are two conditions. The entity has one owner, and it is not already a corporation under the list in paragraph (b) of that section. An LLC formed under state law is not on that list, so a single-member LLC meets both conditions.
Nothing is filed to make this happen. 26 CFR § 301.7701-3(b)(1)(ii) sets the default: a domestic entity with a single owner is disregarded unless it elects otherwise. The election, not the default, is what needs a form. That form is Form 8832. The same regulation sets the other default: if the entity has two or more owners, it is treated as a partnership instead.
Now the part that people miss. Being disregarded is not a general condition. It applies purpose by purpose. Under § 301.7701-2(c)(2), the entity is treated as separate from its owner for:
- employment taxes, if the company has employees,
- certain excise taxes, and
- section 6038A information reporting, if the owner is a foreign person. This is the rule explained further down.
For those purposes the company files in its own name. It is not you.
One more distinction, because it is the source of a lot of bad advice online. "Disregarded" is a federal tax classification. It says nothing about whether your LLC is a separate legal entity under the law of the state where you formed it. The liability protection an LLC gives you comes from state law, not from how the IRS taxes it.
🇺🇸 If the IRS counts you as a U.S. person
Your single-member LLC is disregarded by default. In practice this means:
- The LLC files no separate income tax return. Its income and its deductions go on your own Form 1040.
- You do not send the IRS anything to choose this. Silence is the choice.
- If you want the LLC taxed as a corporation instead, you file Form 8832. After that election the LLC is no longer disregarded.
- An S election is open to you, if you qualify. An LLC gets there by being taxed as a corporation first. Once it is an S corporation, it is not a disregarded entity.
What the word "disregarded" does not get you:
- If you have employees, the company is a separate entity for employment taxes and files those returns in its own name.
- The same is true for the excise taxes the regulation lists.
- Adding one more owner ends the classification. The LLC becomes a partnership by default and files a partnership return (Form 1065). Selling 1% to a co-founder is enough to trigger this.
🌏 If it does not
Start with the good news. The classification rule is the same for you. Your single-member LLC is still disregarded for income tax, and it still files no separate income tax return.
Then read 26 CFR § 301.7701-2(c)(2)(vi), which was written for exactly your situation:
"An entity that is disregarded … is treated as an entity separate from its owner and classified as a corporation for purposes of section 6038A if—(1) The entity is a domestic entity; and (2) One foreign person has direct or indirect sole ownership of the entity."
Read the two conditions slowly, because neither one is about where you live.
Condition 1 is about the company. "Domestic" means formed in the United States. A Wyoming LLC is a domestic entity even if every human being connected to it lives in Seoul, Lagos or Lisbon.
Condition 2 is about the owner. One foreign person owns all of it. "Indirect" is in the text on purpose. Holding the LLC through a foreign holding company does not remove the requirement.
If both conditions are true, your LLC is a corporation for the limited purposes of section 6038A, and here is what that costs you in practice:
- You file Form 5472 for any year the LLC has a reportable transaction with you or another related party. Funding the LLC, paying its bills, and taking money out all count, so an active company files nearly every year. The year you form it and the year you close it both count too.
- Form 5472 is not filed on its own. It is attached to a pro forma Form 1120. "Pro forma" means you are not filing a real corporate income tax return. The IRS instructions say the only items to complete on the Form 1120 are the name and address of the entity and items B and E on the first page.
- You cannot file it electronically. The IRS instructions restrict this filing to mail or fax. Founders who expect to e-file discover this in the last week before the deadline, and then miss it.
Failing to file carries a penalty per form, per year. It is the largest number most non-resident founders will meet in their first year, and it is not reduced because the LLC made no money. Our Brief on the current penalty is linked from this page.
What is the same, and what is different
Most of this table is identical for the two lanes. That is the point. The difference is not created by the disregarded-entity rule. It is created by one extra paragraph, § 301.7701-2(c)(2)(vi), that only turns on when the owner is foreign.
| 🇺🇸 U.S. person | 🌏 Not a U.S. person | |
|---|---|---|
| Default classification of a one-owner LLC | Disregarded | Disregarded (same) |
| Separate income tax return for the LLC | None | None (same) |
| Where the income is reported | Your Form 1040 | Your own return (Form 1040-NR) |
| Employment tax and listed excise taxes | The company is a separate entity | The company is a separate entity (same) |
| Electing corporate treatment on Form 8832 | Available | Available (same) |
| Form 5472 with a pro forma Form 1120 | Not required by the ownership rule | Required for any year with a reportable transaction |
| How that filing is submitted | Not applicable | Paper only. Mail or fax, no e-filing |
| S-corporation election | Available if you qualify | Barred by law. IRC § 1361(b)(1)(C) says a non-resident alien cannot be a shareholder |
One clarification on the last row, because nationality is not the test. The bar applies to a non-resident alien. A foreign citizen who is a resident for tax purposes can hold shares in an S corporation. The question is the same one this whole guide runs on: does the IRS count you as a U.S. person?
Common mistakes
🇺🇸 If the IRS counts you as a U.S. person
- Reading "disregarded" as "no federal tax duties." If the company has employees, it is a separate entity for employment taxes and files in its own name.
- Believing the classification weakens the LLC's liability protection. It does not. One is a tax rule, the other is state law.
- Bringing in a second member and not noticing that the LLC is now a partnership by default, with a partnership return to file.
🌏 If it does not
- Concluding that a disregarded entity with no income and no U.S. profit has nothing to file. It still files Form 5472 with a pro forma Form 1120.
- Trying to e-file that package. The IRS does not accept it electronically, and finding this out at the deadline is how the penalty happens.
- Assuming that owning the LLC through a foreign company solves the problem. The regulation says "direct or indirect sole ownership."
- Assuming the rule depends on where you live. It depends on the entity being domestic and one foreign person owning all of it.
FAQ
Does a disregarded entity file its own tax return?
Not an income tax return. Its income goes on the owner's return. It can still have to file other things: employment tax returns if it has employees, certain excise tax returns, and, if one foreign person owns all of it, Form 5472 attached to a pro forma Form 1120.
Is a single-member LLC automatically a disregarded entity?
Yes. Under 26 CFR § 301.7701-3(b)(1)(ii), a domestic entity with one owner is disregarded unless it elects to be taxed as a corporation. The default is what you get by doing nothing. The election is what needs Form 8832.
Does "disregarded" mean my LLC does not protect me from liability?
No. It is a federal tax classification. Whether your LLC is a separate legal entity, and what that protects, is decided by the law of the state where you formed it, not by the IRS.
I live outside the United States and own 100% of a Wyoming LLC. What do I have to file?
Under 26 CFR § 301.7701-2(c)(2)(vi), your LLC is treated as a corporation for section 6038A purposes because it is a domestic entity and one foreign person owns all of it. So it files Form 5472 with a pro forma Form 1120, on paper, for any year it has a reportable transaction with you or another related party. For an active company that is effectively every year, and forming or closing the LLC counts on its own.
Can I e-file the pro forma Form 1120 and Form 5472?
No. The Instructions for Form 5472 restrict this filing to mail or fax. Plan for the extra days that takes.
What happens if I add a second owner?
The entity no longer has a single owner, so it is no longer disregarded. By default it becomes a partnership and files a partnership return. The Form 5472 rule for foreign-owned disregarded entities stops applying, but other reporting rules for partnerships with foreign partners can start.
Can a disregarded entity be an S corporation?
Not while it is disregarded. An LLC can elect to be taxed as a corporation and then elect S status, and at that point it is no longer a disregarded entity. But the S election has an eligibility rule: IRC § 1361(b)(1)(C) says a non-resident alien cannot be a shareholder. That is a legal bar, not a preference. A foreign citizen who is a U.S. resident for tax purposes can be a shareholder.
Is a foreign-owned disregarded entity really "a corporation" now?
Only for the limited purposes of section 6038A. The IRS instructions use the phrase "for the limited purposes of the requirements under section 6038A." The entity is still disregarded for income tax. Nothing else about it changes.
