LLCs

The limited liability company is the entity form the Internal Revenue Code does not mention: no subchapter, no return of its own, no definition anywhere in the statute. What there is instead is a classification regime that treats the LLC as raw material — State law creates something, and federal tax law then decides, on its own terms, what that something is. Almost every mistake made about LLCs is a mistake about which of those two systems is answering the question in front of you.

The rule

Federal classification does not follow local law. whether an organization is an entity separate from its owners for federal tax purposes is a matter of federal tax law and does not depend on whether the organization is recognised as an entity under local law (Reg. § 301.7701-1(a)(1))^TY2026Verified 2026-08-2126 CFR § 301.7701-1(a)(1), read at law.cornell.edu/cfr/text/26/301.7701-1

That single sentence is the whole architecture. An LLC is unmistakably an entity in the State that chartered it — it holds title, it can sue, its members are shielded from its debts — and none of that decides anything for federal tax purposes.

What is a corporation regardless. a business entity is a corporation for federal tax purposes if it is organised under a federal, State or tribal statute that describes or refers to it as incorporated or as a corporation, body corporate or body politic; if it is an association; if it is a joint-stock company or association, an insurance company, a State-chartered federally insured bank, an entity wholly owned by a State or a foreign government, an entity taxable as a corporation under a Code provision other than IRC § 7701(a)(3), or one of the listed foreign entities (Reg. § 301.7701-2(b))^TY2026Verified 2026-08-2126 CFR § 301.7701-2(b), read at law.cornell.edu/cfr/text/26/301.7701-2

An LLC is not on that list. It is not organised under a statute that calls it a corporation, so it falls outside the first limb (Reg. § 301.7701-2(b)(1)), and every other limb is either about a different kind of entity or, in the case of an association, about the classification election itself. That is precisely why an LLC has a choice: it is an eligible entity under Reg. § 301.7701-3(a).

What it is if nothing is done. unless it elects otherwise, a domestic eligible entity is a partnership if it has two or more members and is disregarded as an entity separate from its owner if it has a single owner (Reg. § 301.7701-3(b)(1))^TY2026Verified 2026-08-2126 CFR § 301.7701-3(b)(1), read at law.cornell.edu/cfr/text/26/301.7701-3

What may be elected. an eligible entity with at least two members may elect to be classified as an association, and so a corporation, or as a partnership; one with a single owner may elect to be classified as an association or to be disregarded. The election is made on Form 8832, and is not accepted unless every item the form and instructions require, including the entity taxpayer identifying number, is supplied (Reg. §§ 301.7701-3(a) and (c)(1)(i))^TY2026Verified 2026-08-2126 CFR § 301.7701-3(a), (c)(1)(i), read at law.cornell.edu/cfr/text/26/301.7701-3

When the election takes effect. an election takes effect on the date the entity specifies on Form 8832, or on the filing date if none is specified. The date specified may not be more than 75 days before the filing date nor more than 12 months after it; an election specifying an earlier or later date is effective 75 days before, or 12 months after, filing (Reg. § 301.7701-3(c)(1)(iii))^TY2026Verified 2026-08-2126 CFR § 301.7701-3(c)(1)(iii), read at law.cornell.edu/cfr/text/26/301.7701-3

The bar on changing again. an eligible entity that elects to change its classification may not change it by election again during the 60 months succeeding the effective date, unless the Commissioner permits it because more than 50 percent of the ownership interests at the effective date of the later election are held by persons who held none on the filing date or the effective date of the earlier one. An election by a newly formed entity effective on the date of formation is not a change (Reg. § 301.7701-3(c)(1)(iv))^TY2026Verified 2026-08-2126 CFR § 301.7701-3(c)(1)(iv), read at law.cornell.edu/cfr/text/26/301.7701-3

The S corporation shortcut. an eligible entity that timely elects to be an S corporation under IRC § 1362(a)(1) is treated as having elected to be classified as an association, provided it meets the other IRC § 1361(b) requirements as of the effective date — so no separate Form 8832 is needed (Reg. § 301.7701-3(c)(1)(v)(C))^TY2026Verified 2026-08-2126 CFR § 301.7701-3(c)(1)(v)(C), read at law.cornell.edu/cfr/text/26/301.7701-3

Employment tax is a separate question. an entity disregarded for any purpose is nonetheless treated as a corporation for the taxes imposed by subtitle C — chapters 21, 22, 23, 23A, 24 and 25 — so it is the employer of its employees, files the Form 94X series and Forms W-2 under its own name and EIN, and is liable for withholding, FICA and FUTA (Reg. § 301.7701-2(c)(2)(iv)(B))^TY2026Verified 2026-08-2126 CFR § 301.7701-2(c)(2)(iv)(B), read at law.cornell.edu/cfr/text/26/301.7701-2

Self-employment tax is not. the disregarded-entity rule still applies to subtitle A, including chapter 2 self-employment tax, so the entity is not the employer of its own owner; the owner is not an employee and is subject to self-employment tax on the entity activities. The same holds for a partner of a partnership that owns the disregarded entity (Reg. § 301.7701-2(c)(2)(iv)(C)(2))^TY2026Verified 2026-08-2126 CFR § 301.7701-2(c)(2)(iv)(C)(2), read at law.cornell.edu/cfr/text/26/301.7701-2

The limited partner exclusion. in computing net earnings from self-employment there is excluded the distributive share of any item of income or loss of a limited partner, as such, other than IRC § 707(c) guaranteed payments to that partner for services actually rendered to or on behalf of the partnership to the extent established to be in the nature of remuneration for those services (IRC § 1402(a)(13))^TY2026Verified 2026-08-21IRC § 1402(a)(13), read at law.cornell.edu/uscode/text/26/1402

Current figures

How it works in practice

Start with the count of members, because that fixes the default and the default is what most LLCs live under. Two or more members and no election: a partnership, filing Form 1065. One member and no election: disregarded, and the activity goes on the owner’s own return — Schedule C for an individual carrying on a trade or business, Schedule E for rentals. The LLC itself files nothing for income tax purposes.

The word to hold onto is default. An LLC that has never filed Form 8832 has still been classified, by the regulation rather than by its members. There is no such thing as a missing classification; the question is only ever whether the classification in force is the one the client wanted.

The effective-date rule is where the practical work is. Both limits are self-correcting rather than fatal: an election naming a date too far back is effective 75 days before filing, and one naming a date too far forward is effective 12 months after. A client who formed an LLC in January and comes to you in June wanting corporate treatment from the start of the year cannot have it under the regulation alone (Reg. § 301.7701-3(c)(1)(iii)), and needs relief for a late election under separate administrative authority.

The 60-month bar is a real constraint on planning and it is easy to overlook because of how it is phrased. It bites on a change of classification, not on the first election, and it is measured from the effective date of the election, not the filing date. An LLC that elects association status effective 1 January 2026 cannot elect back to partnership status effective any date before 1 January 2031, unless the membership has turned over by more than half. A newly formed LLC electing association status effective on the day it is formed has not made a change at all, so its clock has not started.

The deemed election removes what used to be a two-form trap (Reg. § 301.7701-3(c)(1)(v)(C)). An LLC that wants to be an S corporation need not elect association status on Form 8832 first; a timely Form 2553 does both, provided the entity meets the small business corporation requirements on the effective date. The S election presupposes a corporation, and the regulation supplies the classification it needs.

The split between employment tax and self-employment tax produces the most real-world error, because the same entity is treated two ways in the same year. For payroll the disregarded LLC is a corporation: its own EIN, its own Forms 941 and 940, Forms W-2 in its own name. For the owner’s own tax the disregard holds: the LLC is not the owner’s employer, the owner cannot be on that payroll, and the owner pays self-employment tax on the LLC’s net earnings. An owner who has been drawing a W-2 wage from their own single-member LLC has a problem in both directions at once.

The limited partner exclusion is regularly stated too broadly (IRC § 1402(a)(13)). Note what the statute turns on: the words are “limited partner, as such”, which qualify the capacity rather than the label, and guaranteed payments for services actually rendered are expressly carved back in. An LLC member who runs the business is not obviously a limited partner “as such” — unsettled ground, not a rule to apply confidently.

Scenarios

How this has changed

The classification regime itself is the change. Before 1997 an unincorporated entity was tested against four corporate characteristics — continuity of life, centralised management, limited liability and free transferability of interests — and was an association if it had more than two. State legislatures drafting early LLC statutes wrote them to fail that test deliberately, which is why first-generation operating agreements contain provisions whose only purpose was to defeat a regulation that no longer exists. The check-the-box rules replaced the apparatus with an election and a default.

The employment tax rule is the more recent movement and the one still mis-stated in practice (Reg. § 301.7701-2(c)(2)(iv)). When check-the-box first arrived, a disregarded entity was disregarded for payroll too, so the owner filed employment tax returns under their own EIN. That was reversed: the entity became the employer. The carve-back preserving the disregard for the owner’s own self-employment tax came with it, which is why the split exists at all. It is deliberate, not an anomaly.

Exam focus

Expect the default classification to be the answer more often than the election. The recurring shapes are: an LLC with a stated number of members and no election, where the answer is the return that is due; an LLC whose membership changes during the year; a Form 8832 with an effective date outside the window; a client with both a Form 8832 and a Form 2553 in mind, where the point is that the second is enough; and a single-member LLC with employees, where the entity is an employer for its staff but not for its owner.

Read carefully for whether a question is asking about State law or federal tax law. Questions that offer “the LLC is a separate legal entity” as an option are usually testing the classification rule (Reg. § 301.7701-1(a)(1)), and the separate legal existence is true and beside the point. Where a question asks which entities are formed under State law, note that S corporation status is a federal election applied to a corporation formed under State law — the entity is a State creation, the S status is not.

Check yourself

1. An LLC organised in Ohio has three members and has never filed Form 8832. What return does it file for the year?

Answer: Form 1065. Under Reg. § 301.7701-3(b)(1)(i) a domestic eligible entity with two or more members is a partnership unless it elects otherwise, and an LLC is an eligible entity because it is not a corporation under any limb of Reg. § 301.7701-2(b). No election was needed for that result and none is needed to continue it.

2. A single-member LLC files Form 8832 on 1 October 2026 electing association status and specifying an effective date of 1 March 2026. From what date is the election effective?

Answer: 18 July 2026 — 75 days before filing. Reg. § 301.7701-3(c)(1)(iii) provides that an election specifying an effective date more than 75 days before the filing date is effective 75 days before it was filed. The election is not invalid; it simply does not reach March.

3. A domestic LLC with two members files a timely Form 2553 electing S corporation status and meets every requirement of IRC § 1361(b). It does not file Form 8832. Is the S election effective?

Answer: yes. Under Reg. § 301.7701-3(c)(1)(v)(C) an eligible entity that timely elects S status is treated as having elected to be classified as an association, provided it meets the other small business corporation requirements on the effective date. A separate Form 8832 would be redundant, and filing one could start the 60-month clock unnecessarily.

4. A single-member LLC has nine employees and pays its owner a monthly amount recorded as salary. Is the owner’s payment subject to FICA withholding?

Answer: no. The LLC is treated as a corporation for subtitle C purposes as to its nine employees under Reg. § 301.7701-2(c)(2)(iv)(B), but Reg. § 301.7701-2(c)(2)(iv)(C)(2) preserves the disregard for the purpose of employing the owner. The entity is not the owner’s employer, the payment is not wages, and the owner’s liability is self-employment tax on the entity’s net earnings.

5. An LLC that elected association status effective 1 April 2026, with no change in its membership, wants to be classified as a partnership from 1 January 2029. May it elect?

Answer: no. Reg. § 301.7701-3(c)(1)(iv) bars a further classification election during the 60 months succeeding the effective date of the earlier one, so nothing is available before 1 April 2031, and the ownership-change relief cannot help because the membership has not changed.
