Key Takeaways
- New York does NOT clearly extend charging-order-as-exclusive-remedy protection to single-member LLCs — 245 Park Member LLC v. HNA Group, No. 22-1046 (2d Cir. Apr. 8, 2024)
- New York legally requires a written operating agreement, even for a single-member LLC
- New York's veil-piercing test requires (1) complete domination of the LLC by the owner and (2) that domination being used to commit fraud or a wrong against the plaintiff — and courts have acknowledged single-member LLCs are more susceptible in practice to satisfying the "complete domination" prong, since there's no second member's independent conduct to point to. Combined with 245 Park Member LLC's turnover precedent, a New York single-member LLC owner faces meaningfully higher practical exposure than in most states.
- New York has a steeply graduated personal income tax across 9 brackets, with a top marginal state rate of 10.90% on income over $25,000,000 (2026), and New York City residents owe an additional, separate NYC personal income tax of 3.078%–3.876% on top of the state rate — so a New York single-member LLC owner in NYC faces meaningfully higher combined state-plus-city tax exposure than almost anywhere else in the country.

A single-member LLC is a common way solo owners in New York structure their business — but New York is also home to the single most important case in this entire 50-state guide: 245 Park Member LLC v. HNA Group, a 2024 federal appellate decision that let a creditor take a debtor's entire membership interest, not just a charging order on distributions.
This guide covers exactly how a New York single-member LLC works in 2026 — the 245 Park Member LLC turnover risk, the mandatory written operating agreement under § 417, the often-overlooked publication requirement under § 206, and how the LLC is taxed at both the federal and state (plus NYC) level.
What Is a New York Single-Member LLC?
A single-member LLC (SMLLC) is a limited liability company with exactly one owner. It's formed the same way as any other New York LLC — same Articles of Organization, same registered agent requirement — the only difference is ownership structure. By default, the IRS treats a single-member LLC as a "disregarded entity," meaning its income passes through to the owner's personal tax return rather than being taxed at the entity level.
Does New York Protect Single-Member LLCs From Charging Orders?
A charging order limits a creditor of an LLC member (a personal creditor, not a business creditor) to collecting distributions from that member's interest — rather than letting the creditor seize LLC assets outright or force a sale. Many states extend this protection to multi-member LLCs without question, but treat single-member LLCs differently since there's no other member to protect from an unwanted co-owner.
No — and New York has the single most important case in this entire 50-state series. In 245 Park Member LLC v. HNA Group (International) Co., Ltd., No. 22-1046 (2d Cir. Apr. 8, 2024), the Second Circuit affirmed a district court order forcing a debtor to turn over its 100% membership interest in a single-member LLC directly to a creditor — not merely a charging order limiting the creditor to distributions, but the entire interest itself. New York LLC Law § 607 already gave courts discretion between a charging order and other remedies rather than making the charging order exclusive, and courts have read the absence of any other member needing protection as license to go further for single-member LLCs specifically. This makes New York one of the weakest states in the country for single-member LLC asset protection, and it's a real 2024 federal appellate decision, not an old or unsettled one.
Do I Need an Operating Agreement for My New York SMLLC?
Yes — New York is one of only a handful of states that legally requires this. NY LLC Law § 417 requires every LLC, single-member or multi-member, to adopt a written operating agreement within 90 days after the Articles of Organization are filed. It's an internal document (not filed with the state), but the statutory duty is real, and skipping it is a compliance gap, not just a missed best practice.
Your mandatory written operating agreement can also name a successor member and include transfer-on-death language, letting your LLC interest pass to an heir without going through New York probate — a meaningful add-on to a document you're already required to have.
Is a New York Single-Member LLC Easier to Pierce?
Courts everywhere apply the corporate veil doctrine to LLCs, but with only one member, there's no second owner's independent conduct to point to as evidence the company is a genuinely separate entity — which is why single-member LLCs face more practical scrutiny than multi-member LLCs even where the legal test is identical on paper.
New York's veil-piercing test requires (1) complete domination of the LLC by the owner and (2) that domination being used to commit fraud or a wrong against the plaintiff — and courts have acknowledged single-member LLCs are more susceptible in practice to satisfying the "complete domination" prong, since there's no second member's independent conduct to point to. Combined with 245 Park Member LLC's turnover precedent, a New York single-member LLC owner faces meaningfully higher practical exposure than in most states.
Formalities to maintain: keep a dedicated business bank account and never commingle personal and LLC funds, sign every contract and check in the LLC's name (not your own), keep your mandatory written operating agreement current, keep basic records of major decisions and distributions, and adequately capitalize the LLC for the business it actually runs.
How Is a New York Single-Member LLC Taxed?
By default, the IRS disregards a single-member LLC for federal tax purposes — you report business income on Schedule C of your personal return, and you'll owe self-employment tax (Social Security and Medicare) on net earnings. You can elect corporate taxation instead by filing Form 8832 (C-corp) or Form 2553 (S-corp) if that fits your situation better — but unlike a multi-member LLC, a single-member LLC can never elect partnership taxation, since that requires more than one owner.
New York has a steeply graduated personal income tax across 9 brackets, with a top marginal state rate of 10.90% on income over $25,000,000 (2026), and New York City residents owe an additional, separate NYC personal income tax of 3.078%–3.876% on top of the state rate — so a New York single-member LLC owner in NYC faces meaningfully higher combined state-plus-city tax exposure than almost anywhere else in the country.
New York layers two distinct costs on top of each other. First, an annual LLC filing fee ranging from $25 to $4,500 based on New York-source gross income (most single-member LLCs sit in the lowest bracket, at $25). Second — and often overlooked — the LLC Law § 206 publication requirement: every domestic New York LLC, including single-member LLCs with no exemption, must publish notice of formation in two newspapers for six consecutive weeks within 120 days of formation, then file a Certificate of Publication. This is a one-time cost, separate from the annual filing fee, but it's real and can run into four figures in NYC-area counties depending on which newspapers the county designates — plan for it as a genuine formation-stage expense, not an afterthought.
Does My New York SMLLC Need an EIN?
Technically, a single-member LLC with no employees can use the owner's SSN for federal tax filing purposes. In practice, get an EIN anyway (it's free and instant from the IRS) — nearly every New York bank requires one to open a business account, and using an EIN instead of your SSN keeps your personal information off business paperwork and vendor forms.
245 Park Member LLC v. HNA Group is a 2024 decision and remains good law as of 2026 — treat single-member charging-order protection in New York as materially weaker than a charging-order state, not merely untested.
How to Set Up Your New York Single-Member LLC
If You Do It Yourself
Step 1 — File your Articles of Organization.
Form your LLC the same way any other New York LLC is formed — the state doesn't use a different form or process for single-member LLCs.
Step 2 — Appoint a registered agent.
New York calls this role a "Registered Agent" — you can serve as your own if you have a physical in-state address, or use a commercial service for privacy and reliability.
Step 3 — Draft an operating agreement built for a solo owner.
Yes — New York is one of only a handful of states that legally requires this. NY LLC Law § 417 requires every LLC, single-member or multi-member, to adopt a written operating agreement within 90 days after the Articles of Organization are filed. It's an internal document (not filed with the state), but the statutory duty is real, and skipping it is a compliance gap, not just a missed best practice. Your mandatory written operating agreement can also name a successor member and include transfer-on-death language, letting your LLC interest pass to an heir without going through New York probate — a meaningful add-on to a document you're already required to have.
Step 4 — Understand your charging-order exposure.
No — and New York has the single most important case in this entire 50-state series. In 245 Park Member LLC v. HNA Group (International) Co., Ltd., No. 22-1046 (2d Cir. Apr. 8, 2024), the Second Circuit affirmed a district court order forcing a debtor to turn over its 100% membership interest in a single-member LLC directly to a creditor — not merely a charging order limiting the creditor to distributions, but the entire interest itself. New York LLC Law § 607 already gave courts discretion between a charging order and other remedies rather than making the charging order exclusive, and courts have read the absence of any other member needing protection as license to go further for single-member LLCs specifically. This makes New York one of the weakest states in the country for single-member LLC asset protection, and it's a real 2024 federal appellate decision, not an old or unsettled one.
Step 5 — Maintain formalities to avoid alter-ego risk.
keep a dedicated business bank account and never commingle personal and LLC funds, sign every contract and check in the LLC's name (not your own), keep your mandatory written operating agreement current, keep basic records of major decisions and distributions, and adequately capitalize the LLC for the business it actually runs.
Step 6 — Get an EIN and open a business bank account.
Technically, a single-member LLC with no employees can use the owner's SSN for federal tax filing purposes. In practice, get an EIN anyway (it's free and instant from the IRS) — nearly every New York bank requires one to open a business account, and using an EIN instead of your SSN keeps your personal information off business paperwork and vendor forms.
Step 7 — Handle ongoing state compliance.
New York layers two distinct costs on top of each other. First, an annual LLC filing fee ranging from $25 to $4,500 based on New York-source gross income (most single-member LLCs sit in the lowest bracket, at $25). Second — and often overlooked — the LLC Law § 206 publication requirement: every domestic New York LLC, including single-member LLCs with no exemption, must publish notice of formation in two newspapers for six consecutive weeks within 120 days of formation, then file a Certificate of Publication. This is a one-time cost, separate from the annual filing fee, but it's real and can run into four figures in NYC-area counties depending on which newspapers the county designates — plan for it as a genuine formation-stage expense, not an afterthought. New York has a steeply graduated personal income tax across 9 brackets, with a top marginal state rate of 10.90% on income over $25,000,000 (2026), and New York City residents owe an additional, separate NYC personal income tax of 3.078%–3.876% on top of the state rate — so a New York single-member LLC owner in NYC faces meaningfully higher combined state-plus-city tax exposure than almost anywhere else in the country.
Step 8 — Watch for New York-specific SMLLC traps.
New York has two well-known SMLLC-specific traps beyond the charging-order gap. First, the mandatory written operating agreement under § 417 — due within 90 days of formation, and easy to miss if you're used to states where an operating agreement is optional. Second, the § 206 publication requirement — publishing notice of formation in two newspapers for six weeks and filing a Certificate of Publication, a one-time but real cost, especially in NYC-area counties, that catches new owners off guard because it's separate from and in addition to the annual filing fee.

When Should You Talk to an Attorney About Your New York Single-Member LLC?
Talk to an attorney before finalizing your New York single-member LLC's structure if asset protection from personal creditors is a primary goal (245 Park Member LLC materially weakens the default protection here), if you're deciding whether to add a nominal second member specifically to strengthen your position against a turnover-style remedy, or if you want help budgeting and executing the § 206 publication requirement correctly so your LLC doesn't fall out of good standing.
Is New York a State Where SMLLC Asset Protection Matters More?
New York is arguably the most consequential state in this guide for a single-member LLC owner specifically. 245 Park Member LLC v. HNA Group let a creditor take a debtor's entire 100% membership interest rather than being limited to a charging order — a gap even larger than Florida's Olmstead carve-out, and confirmed by a federal circuit court in 2024, not a state supreme court applying older reasoning. If asset protection is a primary reason you're forming an LLC, New York's default posture is worth understanding clearly, and worth weighing against forming your primary asset-holding entity in a stronger charging-order state instead.
What You Actually Get With LLC Attorney's New York SMLLC Formation
The part of forming a New York single-member LLC that generic templates miss is 245 Park Member LLC — most multi-state formation services don't flag that New York single-member LLCs face weaker charging-order protection than multi-member ones, on top of a mandatory operating agreement and a publication requirement most states don't have at all. LLC Attorney builds your formation and operating agreement around all three realities from the start.
- Single-member LLC formation in New York, starting at $0 + state fees.
- Solo-owner operating agreement with transfer-on-death provisions, starting at $49.
- Charging-order, alter-ego, and tax considerations addressed for your specific state — not a generic multi-state template.
- Access to professionally trained Business Success Advisors at no charge, plus flat-fee attorney consultations (no retainer) for asset-protection questions.
New York's single-member LLC rules have real traps — 245 Park Member LLC, the mandatory written operating agreement, and the publication requirement — and LLC Attorney makes sure your formation accounts for all three from day one.

Frequently Asked Questions
No. In 245 Park Member LLC v. HNA Group, No. 22-1046 (2d Cir. Apr. 8, 2024), the Second Circuit affirmed an order forcing a debtor to turn over its entire 100% membership interest in a single-member LLC to a creditor, rather than limiting the creditor to a charging order on distributions. New York LLC Law § 607 already gives courts discretion beyond a charging order, and this 2024 decision confirms courts will use that discretion more aggressively against single-member LLCs specifically.
Yes — New York is one of the only states that legally requires this. NY LLC Law § 417 requires every LLC, including single-member LLCs, to adopt a written operating agreement within 90 days of filing the Articles of Organization.
New York's veil-piercing test looks at complete domination of the LLC plus fraud or wrongdoing against the plaintiff, and courts have acknowledged single-member LLCs are more susceptible to satisfying the domination prong. Combined with 245 Park Member LLC's turnover precedent, keeping clean formalities matters more in New York than in almost any other state.
Not a dedicated statute, but § 417's written operating agreement mandate applies to every LLC regardless of member count, and 245 Park Member LLC shows courts reasoning specifically from single-member status to justify a stronger creditor remedy.
No. Partnership taxation requires at least two members. A New York single-member LLC can only be taxed as a disregarded entity (the default), or elect C-corp or S-corp taxation instead.
Technically optional if the LLC has no employees (you can use your SSN instead), but get one anyway — it's free from the IRS, nearly every New York bank requires it to open a business account, and it keeps your SSN off business paperwork.
Yes. Your mandatory written operating agreement can name a successor member and include transfer-on-death language, letting your LLC interest pass to an heir outside of New York's probate process.
Some New York single-member LLC owners add a nominal second member (often a spouse or family trust) specifically because 245 Park Member LLC's reasoning turned on the entity having only one member — a second member changes the calculus a court would apply. This has real tradeoffs in tax treatment and governance, so it's worth discussing with an attorney rather than doing informally, especially given New York's unusually weak SMLLC asset-protection posture.
Yes. LLC Attorney forms single-member LLCs in New York, including a solo-owner operating agreement, starting at $0 + state fees.
