An LLC has no tax classification of its own under federal law. By default, the IRS treats a one-owner LLC as a disregarded entity (taxed like a sole proprietorship) and an LLC with two or more members as a partnership; either kind can instead elect to be taxed as a corporation with Form 8832, or as an S corporation with Form 2553. Choosing well can change how much Social Security and Medicare tax you pay, which returns you file, and how much paperwork you sign up for.
Below is how each classification works, when an election makes sense, the deadlines that trip people up, and a worked example with real numbers. Federal rules only; your state may tax LLCs differently.
The default rules: what happens if you file nothing
Single-member LLC: disregarded entity
The IRS says a one-member LLC is "treated as an entity disregarded as separate from its owner" for income tax, unless it elects otherwise. If you own it personally, the business results go on Schedule C of your Form 1040, and your net profit is subject to self-employment tax in the same way as a sole proprietorship.
Disregarded does not mean invisible. For employment taxes and certain excise taxes, the IRS still treats the LLC as a separate entity, so if it hires employees it must report payroll taxes under its own name and employer identification number (EIN).
Multi-member LLC: partnership
A domestic LLC with two or more members is classified as a partnership by default. It files Form 1065, issues each member a Schedule K-1, and pays no federal income tax itself; the members pay tax on their shares.
Changing the classification: Form 8832
Form 8832, Entity Classification Election, lets an eligible entity choose a classification other than its default. An LLC uses it to elect to be taxed as a C corporation, or, less commonly, to move between classifications later on.
- Effective date window: the election cannot take effect more than 75 days before the date you file it, or more than 12 months after. Pick a date outside that window and it is moved inside it.
- The 60-month rule: once an entity changes its classification by election, it generally cannot change again by election for 60 months after the effective date. An initial election by a newly formed entity, effective on its formation date, is not treated as a change for this purpose. The IRS can permit an earlier change by private letter ruling in some cases, such as when more than 50% of the ownership has changed hands.
- Late elections: the IRS says late election relief may be available in certain circumstances, so a missed date is worth raising with your preparer rather than ignoring.
You do not file Form 8832 just to keep the default classification.
LLC taxed as an S corp: Form 2553
Most owners who talk about "electing S corp" want pass-through treatment but with part of the profit paid as wages and the rest as distributions. An LLC gets there by filing Form 2553. The Form 2553 instructions say an eligible entity that makes a valid S election is treated as a corporation from the election's effective date and does not need to file Form 8832 as well.
Eligibility
- Domestic entity, with no more than 100 shareholders (members).
- Only individuals, estates and certain trusts and exempt organizations as owners; no nonresident alien owners, and no partnerships or corporations as owners.
- Only one class of stock, disregarding differences in voting rights. For an LLC, operating agreement terms that give members unequal rights to distributions can put this at risk, so have the agreement reviewed before you elect.
- A permitted tax year, usually the calendar year.
The deadline
File Form 2553 no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the tax year before. For a calendar-year LLC that wants S status from January 1, 2027, that means any time in 2026, or by March 15, 2027. Every member must consent and sign.
Miss it, and Revenue Procedure 2013-30 offers simplified late-election relief if you request it within 3 years and 75 days of the intended effective date and can show reasonable cause; outside that, you generally need a private letter ruling and a user fee.
The catch: reasonable compensation
An S corporation must pay a shareholder who works in the business reasonable compensation as wages before taking non-wage distributions. Those wages run through payroll with withholding, Form 941 filings and W-2s. Setting your salary artificially low to save employment tax is exactly what the IRS looks for.
Worked example: a Tucson drone-mapping LLC
Priya owns Kestrel Aerial Mapping LLC, a single-member LLC in Tucson. In 2026 it expects net profit of $120,000 before any owner pay.
- Default (disregarded): the full $120,000 goes on her Schedule C. All of it is net earnings from self-employment, so all of it feeds into Schedule SE.
- With an S election: suppose that, after looking at what comparable surveyors in her market are paid, she and her CPA settle on a reasonable salary of $70,000. The LLC runs payroll on that salary, and the remaining $50,000 of profit passes through to her on a K-1 from Form 1120-S.
- The tax difference: wages carry Social Security tax at 6.2% and Medicare tax at 1.45% each for employee and employer in 2026, so 15.3% combined. The $50,000 passed through as an S corporation distribution is not subject to those employment taxes. A rough upper bound on the saving is $50,000 × 15.3% = $7,650; the actual self-employment tax that amount would have carried on Schedule C is somewhat lower, because Schedule SE applies the rate to a reduced base.
- The costs on the other side: a separate Form 1120-S, a payroll provider, quarterly payroll filings, state unemployment registration, and in some states franchise or entity taxes. If those costs eat most of the saving, the election is not worth it.
If Kestrel expected $45,000 of profit rather than $120,000, a reasonable salary might absorb nearly all of it, and the election would mostly add cost. That is why the S election tends to suit owners with steady profit well above a market salary.
Choosing a C corporation instead
Electing C corporation status on Form 8832 makes the LLC a separate taxpayer that files Form 1120 and pays the flat 21% corporate rate. Profit paid out as dividends is then taxed again to the owners. Founders usually consider this only when they plan to retain most profit in the business or raise outside equity. Because of the 60-month rule, it is a hard decision to reverse.
Common mistakes with LLC elections
- Filing both forms when electing S status. Form 2553 alone is enough for an eligible LLC.
- Missing a member's signature on Form 2553, which can invalidate the election.
- Electing S status and never running payroll, taking all profit as distributions.
- Forgetting the effective-date window on Form 8832 and assuming an election can be backdated to the start of the year.
- Ignoring state treatment, since not every state follows the federal classification for its own taxes and fees.

The classification changes which return gets filed, but every one of them is built from the same books. HelloBooks keeps a customizable chart of accounts, so a disregarded LLC can track owner draws, while an S corp LLC can separate officer wages, payroll tax expense and shareholder distributions. If you run payroll in HelloTime (TimeX), the HelloBooks sister product, payroll journals sync into your books instead of being keyed by hand. The P&L and balance sheet show your real profit through the year, which is the number you and your CPA need when deciding whether an election pays for itself, and the trial balance and year-end close give your preparer a clean starting point for Schedule C, Form 1065 or Form 1120-S. The election itself is filed by you or your CPA with the IRS.
This is general information as of November 2026 about federal LLC classification, not tax or legal advice; check the IRS instructions for Forms 8832 and 2553 or talk to a CPA before you elect.
