New York Single-Member LLC — Formation & Tax Guide

A single-member LLC in New York provides liability protection for sole owners while keeping taxes simple. However, NY's unique requirements (mandatory operating agreement, publication, state income tax) make it more complex than single-member LLCs in no-income-tax states. See all LLC types or our formation guide.

NY-Specific Considerations for Single-Member LLCs

Operating agreement is mandatory: Even as a solo owner, NY LLC Law Section 417 requires a written operating agreement. This is not optional. Include: your name, capital contribution, management authority, dissolution triggers, and succession provisions.

Publication still required: Single-member LLCs must complete the full publication requirement (2 newspapers, 6 weeks). No exemption for sole owners. Budget $300-$2,000 depending on county.

PTET election not available (by default): The Pass-Through Entity Tax election requires either multi-member status or S-corp election. Single-member disregarded entities cannot use PTET. If you want PTET benefits (SALT cap bypass), you must elect S-corp status.

Privacy on filing: NY's Articles of Organization do not require member names. A single-member LLC's owner is not identified on the DOS filing — providing meaningful privacy (though the publication notice may include your name or the LLC name).

Tax Treatment

Default (disregarded entity):

• Report all income on NY Form IT-201 (resident) or IT-203 (non-resident) — Schedule C flows to state return
• Pay NY income tax (4%-10.9%) on all NY-source income
• Pay NYC income tax (3.078%-3.876%) if NYC resident
• Pay IT-204-LL filing fee ($25 minimum at entity level)
• No separate LLC return needed with NY Tax Dept for disregarded entities (reported on personal return)

S-corp election:

• Enables PTET election (major SALT benefit)
• Saves self-employment tax on distributions
• Must file CT-3-S and pay yourself W-2 salary
• More complex but significant tax savings above $80K net profit

FAQ

Does a single-member LLC need to file IT-204 (partnership return)?

No. A disregarded entity does not file IT-204. The income is reported on the member's personal return. However, you DO still owe the IT-204-LL filing fee ($25+) as the entity.

Is a single-member LLC more vulnerable to veil piercing in NY?

NY courts analyze the same factors for single and multi-member LLCs: commingling funds, inadequate capitalization, using the LLC for personal purposes. Having a written operating agreement (required anyway), separate bank account, and proper records protects against piercing.

Can a single-member LLC add members later?

Yes. Amend your operating agreement to admit new members. No state filing required (Articles do not list members). This changes your federal classification from disregarded entity to partnership (Form 1065 required going forward).
