How an LLC Is Taxed (Classification)

An LLC is a creature of state law. You form it in Delaware, Wyoming or New Mexico, and the state gives you a company. The IRS does not have a matching tax category called "LLC," and there is no federal return that an LLC files as an LLC.

So the IRS assigns your LLC to one of the categories it does have. It taxes your company as a sole proprietorship, as a partnership, or as a corporation. Which one you get depends on a single fact: how many owners the LLC has. You never chose that classification, and nobody tells you what it is.

You can override the default by filing a form. Most founders never do, and most of them are right not to. But you should know what you were given by default, because it decides which return you file, when you file it, and what happens if you file nothing.

What the rules actually require

The classification rules are in the Treasury regulations, at 26 CFR § 301.7701-3. An LLC is what the regulation calls an "eligible entity," which means it is allowed to pick its own tax classification. If it does not pick, the regulation picks for it.

Here are the two defaults for a domestic LLC:

• One owner. The LLC is a disregarded entity. The IRS treats it as not separate from its owner. The company still exists under state law, and your liability protection is unaffected, but for federal income tax the IRS looks straight through it to you.
• Two or more owners. The LLC is a partnership. It files its own information return, Form 1065, and hands each owner a Schedule K-1 showing that owner's share of the income. The partnership itself does not pay federal income tax. The owners pay it on their own returns.

Note what does not appear in either rule. Nothing about citizenship. Nothing about where the owner lives. Nothing about where the owner's money is. The default classification of your LLC is decided by counting members, and that is all.

Changing the default

You change the classification by filing Form 8832, the Entity Classification Election. That is how an LLC becomes a corporation for tax purposes. A single-member LLC that files Form 8832 stops being disregarded. A multi-member LLC that files it stops being a partnership.

The timing is not free-form. The regulation lets you pick an effective date, but that date cannot be more than 75 days before the day you file the form, and it cannot be more than 12 months after it. So if you file Form 8832 on 1 June, the earliest effective date you can ask for is 18 March, and the latest is 1 June of the following year.

Missing that window is not always fatal. Rev. Proc. 2009-41 lets an eligible entity request relief for a late classification election filed within 3 years and 75 days of the requested effective date, if it meets the conditions in that procedure. Outside those conditions, the ordinary route is closed.

There is a second limit that catches people who treat this as a switch they can flip. Once an entity elects to change its classification, § 301.7701-3(c)(1)(iv) blocks it from electing again for 60 months after the effective date of that election. Two things narrow the rule. The regulation says an election by a newly formed entity that is effective on the date of formation "is not considered a change" for this purpose, so a first election made at formation does not start the clock. And the Commissioner may allow an earlier change if more than 50% of the ownership interests are held by people who owned no interest at the time of the prior election. Neither is a plan. If you switch an LLC that has been running on its default classification, assume five years.

The S-corporation election is a different form, Form 2553, and a different set of conditions. It is not part of the default rules at all. It is discussed below, because the answer to "can I use it" is one of the few places where the two lanes truly split.

🇺🇸 If the IRS counts you as a U.S. person

Your defaults are the ones above, and the filing that follows is ordinary.

One owner. The LLC is disregarded. You do not file a separate business return. You report the business income and expenses on Schedule C, attached to your personal Form 1040. For a small operation this is the lightest reporting the tax code offers. It is one of the real reasons the single-member LLC is so common.

Two or more owners. The LLC files Form 1065 and issues a Schedule K-1 to each member. Each member reports their K-1 amount on their own 1040.

If you want corporate treatment. File Form 8832 and the LLC is taxed as a corporation, filing Form 1120. If what you want is the S-corporation regime, file Form 2553 instead. Under § 301.7701-3(c)(1)(v)(C), a timely S election is itself treated as an election to be classified as a corporation, so an LLC does not have to file Form 8832 first. You are eligible for the S election, which is the point: the door is open to you, and whether you walk through it is a business decision rather than a legal one.

Nothing here requires an extra information return. If you are a U.S. person with a single-member LLC and no employees, the whole federal reporting duty for the company can be one extra schedule on the return you were filing anyway.

🌏 If it does not

Start with the good news, because it is genuinely good news. The default classification does not change. A single-member LLC owned by a person in Seoul, São Paulo or Berlin is still a disregarded entity. A two-member LLC owned by two foreigners is still a partnership. There is no separate foreign-owner classification rule, and anyone who tells you a foreigner "cannot own a disregarded entity" is wrong.

Now the part that costs people money.

A single-member LLC that is foreign-owned has to file Form 5472, attached to a pro forma Form 1120. The rule is in 26 CFR § 301.7701-2(c)(2)(vi): a domestic disregarded entity that is solely owned by one foreign person is treated as a corporation for the reporting rules of IRC § 6038A. That is the entire change, and it is a reporting change only. Form 5472 is an information return. It reports the dealings between the LLC and its foreign owner, and between the LLC and other related parties. The pro forma 1120 is a mostly empty corporate return that exists to carry the 5472 to the IRS, and the Form 5472 instructions say to file it by the due date of that return, including extensions. Filing it does not mean your LLC is taxed as a corporation. Its classification is unchanged. It is still disregarded.

What triggers the filing is a transaction, not income. Form 5472 is due for any year in which the LLC had a reportable transaction with a related party. For a foreign-owned disregarded LLC the definition is wide: 26 CFR § 1.6038A-2(b)(3)(xi) counts "amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity, including contributions to and distributions from the entity." Money you put into the LLC is a reportable transaction. Money you take out is one. So an LLC that made no sales at all normally still has a filing duty in its first year, because it was funded.

There is one narrow exception, and it is narrower than it sounds. 26 CFR § 1.6038A-2(e)(1) says a reporting corporation is not required to file Form 5472 if it had no transactions of the reportable types with any related party during the year. An LLC that sat completely still, with no money moving in or out and nothing paid on its behalf, is outside the rule for that year. One transfer from your own account puts you back inside it. Do not build a filing position on this.

The penalty for not filing Form 5472 is $25,000 for each year you miss. IRC § 6038A(d)(1) sets it, and it attaches to the failure to file, not to any tax owed. If the failure continues more than 90 days after the IRS notifies you, § 6038A(d)(2) adds a further $25,000 for each 30-day period the failure runs on. An LLC that earned nothing and owed nothing can still be assessed the full amount.

This is the fact that overturns the most common belief about LLCs. Founders are told an LLC is "just pass-through, so there is barely anything to file." For a foreign-owned single-member LLC, the reporting burden is heavier than it is for an American-owned one, not lighter. The American files a schedule. The foreigner files a schedule-equivalent in their own country, plus a corporate shell return, plus an information return with a $25,000 penalty behind it.

The S-corporation election is closed to you, by statute. This is not a practical difficulty or a paperwork hurdle. 26 U.S.C. § 1361(b)(1)(C) says an S corporation cannot have a nonresident alien as a shareholder. If a nonresident alien holds shares, the entity is not an S corporation. Read the term carefully. It says nonresident alien, not foreign national. A foreign citizen who is a resident alien for tax purposes, for example a green card holder, can be an S-corporation shareholder. The test is your tax residency, not your passport. Our page on who counts as a U.S. person explains how that test is run.

Same rule, different paperwork

Most of this table is identical down both columns. That is the honest answer, and it is worth seeing the sameness laid out before the differences.

The classification rules do not care where you live. The reporting rules care very much.

Common mistakes

🇺🇸 If the IRS counts you as a U.S. person

• Thinking "LLC" is a tax status. It is not. Ask instead whether your LLC is disregarded, a partnership, or a corporation, because that is the question the IRS is answering.
• Switching an established LLC off its default classification with Form 8832 or Form 2553 because a video said the S-corporation "saves tax," then finding the 60-month lock in the way when the business changes shape a year later.
• Adding a second member (a spouse, a co-founder) without noticing that the LLC has just become a partnership by default, with a Form 1065 duty that did not exist before.

🌏 If it does not

• Believing that no U.S. income means no U.S. filing. The trigger for Form 5472 is a reportable transaction, not revenue, and funding your own LLC is a reportable transaction. A foreign-owned single-member LLC with zero sales normally still owes Form 5472 and the pro forma 1120, and the $25,000 penalty is for not filing, not for not paying.
• Thinking the pro forma Form 1120 means the LLC is now taxed as a corporation. It is not. It is still disregarded. The 1120 is a carrier for the information return.
• Trying to elect S-corporation status because a U.S.-focused article recommended it. If you are a nonresident alien, the statute does not allow you to be a shareholder.
• Assuming an accountant who handles domestic small businesses knows the 5472 rule. Many do not, because their clients never trigger it.

FAQ

What is the default tax classification of a single-member LLC?

It is a disregarded entity. Under 26 CFR § 301.7701-3, the IRS treats a one-owner LLC as not separate from its owner for federal income tax. The company still exists, and the liability shield is unaffected. Only the tax treatment looks through it.

Does the default change if the owner is not American?

No. The default classification depends on the number of members, not on where the owner lives or what passport the owner holds. A foreign-owned single-member LLC is still disregarded. What changes is the reporting: it must file Form 5472 with a pro forma Form 1120.

Is a foreign-owned LLC with no income really required to file?

Usually yes, and the reason matters. The trigger is not income. It is a reportable transaction with a related party, and under 26 CFR § 1.6038A-2(b)(3)(xi) that includes contributions to and distributions from the LLC and amounts paid in connection with forming it. An LLC you funded but never traded through has had a reportable transaction. The one exception, in 26 CFR § 1.6038A-2(e)(1), covers a year in which there were no reportable transactions with any related party at all. That is a narrow position to hold, and the $25,000 penalty is for the failure to file, not for unpaid tax.

If my LLC files a Form 1120, is it now a corporation?

Not if it is a pro forma 1120 filed only to carry Form 5472. The LLC's classification is still disregarded. You become a corporation for tax purposes only by electing it on Form 8832.

Can I choose S-corporation status if I live outside the United States?

If you are a nonresident alien, no. 26 U.S.C. § 1361(b)(1)(C) says an S corporation cannot have a nonresident alien as a shareholder. If you are a foreign citizen who is a resident alien for tax purposes, you can. The line is drawn by your tax residency, not your nationality.

How late can I file Form 8832 and still have it apply to a past date?

The election can take effect no more than 75 days before the date you file the form. It can also take effect up to 12 months after that date. If you miss that window, Rev. Proc. 2009-41 allows a request for relief for a late classification election filed within 3 years and 75 days of the requested effective date, subject to the conditions in that procedure.

If I elect corporate treatment and regret it, can I switch back?

Not quickly. After an election to change classification takes effect, the entity generally cannot elect a different classification for 60 months. Two carve-outs exist: an initial election by a newly formed entity effective on its date of formation is not counted as a change, and the Commissioner may allow an earlier switch if more than half the ownership interests have turned over. Outside those, treat the election as a five-year decision.

My LLC has two members. Do we file anything separate?

Yes. By default a multi-member LLC is a partnership. It files Form 1065 and gives each member a Schedule K-1. The partnership itself does not pay federal income tax; the members report their shares on their own returns.
