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 the default tax classification for an LLC?
Single-member LLC: disregarded entity (Schedule C on personal 1040). Multi-member LLC: partnership (Form 1065 with K-1s).
How do I elect S-Corp treatment?
File Form 2553 with the IRS. Must be signed by all members. Late election relief available for many missed deadlines.
When is S-Corp election beneficial?
Generally once net profit (after expenses, before owner pay) crosses $60-80k. Saves on SE tax. Below that, payroll complexity outweighs savings.
Can a single-member LLC elect S-Corp?
Yes. Owner becomes employee-shareholder, draws W-2 wages plus distributions.
Can non-US persons own an S-Corp-elected LLC?
No. S-Corp eligibility restricts ownership to US persons (individuals or qualifying entities). Non-US members make the LLC ineligible for S-Corp.
When does C-Corp election make sense?
Raising venture capital (investors require C-Corp), planning for QSBS exclusion, certain international structures. Rare for typical small businesses due to double taxation.
Can I switch back from S-Corp to default?
Yes, but 60-month waiting period before re-electing S-Corp. Some exceptions allow earlier re-election.
Does S-Corp election affect liability protection?
No. The LLC liability shield is unchanged. Only federal tax treatment changes.
Do I need a new EIN to change classification?
Generally no for S-Corp or C-Corp election from default. EIN required when single-member converts to multi-member (default partnership) in some cases.
