Llc Tax Classification · all 51 jurisdictions

LLC tax classification. Four options. The right pick depends on profit and goals.

An LLC is a state-created entity. Federal tax classification is separate, determined either by default rule (based on member count) or by affirmative election. The four possible classifications produce dramatically different tax outcomes. This guide explains each, when to choose each, and the timing rules for electing or reverting.

In depth

The full explanation.

01

Disregarded entity

Single-member LLC default. The LLC is "disregarded" for federal tax: profit/loss flows directly to the owner's personal return on Schedule C. Self-employment tax applies to all net profit (15.3% × 92.35% × net profit). Owner pays personal income tax on net profit at marginal rates. Simplest classification; no separate entity return.

02

Partnership

Multi-member LLC default. Files Form 1065 (informational return) at the entity level. Each member receives Schedule K-1 reporting their allocated income, deductions, credits. Members pay tax on K-1 amounts on personal returns. Active members pay SE tax on distributive share. Allocations can be disproportionate to ownership if "substantial economic effect" is satisfied. Common for multi-owner businesses.

03

S-Corp election

Filed on Form 2553. Effect: LLC is taxed as S-Corp for federal purposes. Owner-employees who work in the business receive W-2 wages (subject to FICA) plus distributions (not subject to SE tax). Saves SE tax on distribution portion. Requires payroll service, "reasonable compensation" analysis, and Form 1120-S annual return. Eligibility: US individuals or qualifying entities only (no non-US persons, no partnerships, no most trusts). Max 100 shareholders. Single class of stock requirement.

04

C-Corp election

Filed on Form 8832. Effect: LLC is taxed as C-Corp for federal purposes. Entity pays 21% federal corporate tax on profits. Distributions to owners are dividends, taxed at 15-23.8% based on bracket. Double taxation. Rarely chosen by LLCs except: (1) raising venture capital where Delaware C-Corp is investor-required; (2) planning for QSBS exclusion under Section 1202; (3) certain international structures.

05

Default rules

Single-member LLC: disregarded entity. Multi-member LLC: partnership. Both can elect S-Corp or C-Corp. Adding/removing members can shift default classification: single-member becoming multi-member shifts from disregarded to partnership (new EIN may be required, separate Form 1065).

06

Election timing

Form 2553 (S-Corp): file by 75 days into the tax year you want it effective, or any time during prior year. Late election relief available under Rev. Proc. 2013-30 for many situations. Form 8832 (C-Corp): file any time, with effective date 75 days before to 12 months after filing.

07

Reverting

Once you elect a classification, reverting is restricted. S-Corp reverting to default: 60-month waiting period before re-electing S-Corp. C-Corp reverting to default: may trigger deemed liquidation (taxable). Plan elections carefully.

08

State conformity

Most states follow federal classification. California: separate $800 minimum franchise tax for LLCs + additional fees if S-Corp elected. Tennessee: separate franchise + excise tax. Several states have unique treatment. We map your state-specific implications.

FAQ

Common questions.

What is LLC tax classification?
LLC tax classification is how the IRS taxes your LLC, which is flexible: by default a single-member LLC is a disregarded entity and a multi-member one a partnership, but it can elect to be taxed as an S-corp or a C-corp. The entity stays an LLC; only the tax treatment changes. We help you choose the right classification.
What are the tax classification options for an LLC?
Four main ones: disregarded entity (single-member default), partnership (multi-member default), S-corporation (by election), and C-corporation (by election). Each has different filings and tax effects. We flag which fits your income, ownership, and goals so you are not on a default that costs you.
What is the default classification?
A single-member LLC is a disregarded entity taxed on the owner's return, and a multi-member LLC is a partnership filing an information return with K-1s, unless you elect otherwise. Many LLCs stay on the default, and we flag when electing something else would help.
When should I elect S-corp classification?
Once profit is high enough that the self-employment tax saved beats the payroll and second return, often low-to-mid five figures and up. Below that the default is simpler. We run your numbers before you elect so the classification change saves rather than costs.
When would an LLC elect C-corp classification?
Occasionally, for reasons like retaining earnings at corporate rates, certain benefit plans, or fundraising, though most small LLCs are better off pass-through or S-corp. C-corp taxation brings potential double taxation. We help you weigh whether it genuinely fits before electing.
Does changing classification change my entity?
No: your LLC stays an LLC legally regardless of how it is taxed, since classification is a federal tax choice layered on top of the entity. You do not convert at the state to change tax treatment, and we keep your LLC and just change the IRS classification.
Can I change classification later?
Yes, but with limits: after electing corporate or S-corp treatment there is generally a five-year wait before changing again, so it is not a casual switch. We flag the consequences before you elect so you do not lock yourself out of a change you may want.
Does my state follow the federal classification?
Usually, but not always: many states follow your federal classification, while some require a separate election or tax certain classifications differently. We flag how your state treats the classification so there are no surprises at the state level.
Can File.Business help me classify my LLC?
Yes: we form the LLC, run your numbers, and file the appropriate election, S-corp or otherwise, so your LLC's tax classification is chosen deliberately to fit your income and plans rather than left on a default that may not suit you.
