Key Takeaways
- Delaware extends charging-order-as-exclusive-remedy protection to single-member LLCs the same as multi-member LLCs — 6 Del. C. § 18-703 (whether 1 member or more than 1 member)
- Delaware does not legally require a written operating agreement, but you should have one anyway
- Delaware courts are notably reluctant to pierce the LLC veil — Verdantus Advisors, LLC v. Parker Infrastructure Partners, LLC (Del. Ch. 2022) requires showing the entity existed for "no other purpose than as a vehicle for fraud," a demanding standard. The countervailing risk is emerging reverse-veil-piercing exposure: Sky Cable, LLC v. DirecTV, Inc., 886 F.3d 375 (4th Cir. 2018), predicting how Delaware law would apply, suggested Delaware would recognize reverse veil-piercing especially readily against single-member entities used purely as asset-holding repositories. That's a federal court's prediction of Delaware law, not a Delaware state-court holding, but it's worth knowing about if your single-member LLC exists solely to hold assets rather than to run an active business.
- Delaware has a graduated personal income tax ranging from 2.2% up to a top marginal rate of 6.6% on income over $60,000. This applies to a Delaware-resident single-member LLC owner's pass-through profit in addition to federal income tax and self-employment tax — but a single-member LLC formed in Delaware and owned by an out-of-state resident who doesn't do business in Delaware generally owes no Delaware income tax at all, which is a major reason many out-of-state owners choose Delaware for holding-company structures.
- Yes. 6 Del. C. § 18-703's "whether the limited liability company has 1 member or more than 1 member" language names single-member LLCs directly and guarantees them the same exclusive-remedy charging-order protection multi-member LLCs receive — one of the clearest examples of deliberate SMLLC-inclusive statutory drafting in this guide.

A single-member LLC is the most common way solo owners in Delaware structure their business — and Delaware is one of the states that wrote explicit, named single-member charging-order protection directly into its statute decades ago, longer than almost any other jurisdiction in this guide.
This guide covers exactly how a Delaware single-member LLC works in 2026 — the § 18-703 "1 member or more than 1 member" language, the flat $300 annual tax, whether you need a written operating agreement, alter-ego and reverse-piercing risk, and how the LLC is taxed at both the federal and state level.
What Is a Delaware 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 Delaware 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 Delaware 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.
Yes, explicitly and by name. 6 Del. C. § 18-703 states that a charging order is a judgment creditor's exclusive remedy, and that attachment, garnishment, foreclosure, and other remedies are unavailable "whether the limited liability company has 1 member or more than 1 member." Delaware was one of the first states to write single-member protection directly into its LLC statute rather than leaving the question to case law, which is part of why it's a common jurisdiction of choice for holding companies built from single-member LLCs.
Do I Need an Operating Agreement for My Delaware SMLLC?
No. 6 Del. C. § 18-101(7) defines a limited liability company agreement broadly as "any agreement...written, oral or implied," and expressly states an LLC "is not required to execute its limited liability company agreement" at all. Most single-member LLCs adopt a written agreement anyway, since Delaware courts will enforce whatever terms it contains with unusually broad deference to the parties' own drafting.
An operating agreement can name a successor member and include transfer-on-death language, letting your LLC interest pass to an heir without going through Delaware probate — worth including even though Delaware doesn't require the document to exist in writing, or at all.
Is a Delaware 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.
Delaware courts are notably reluctant to pierce the LLC veil — Verdantus Advisors, LLC v. Parker Infrastructure Partners, LLC (Del. Ch. 2022) requires showing the entity existed for "no other purpose than as a vehicle for fraud," a demanding standard. The countervailing risk is emerging reverse-veil-piercing exposure: Sky Cable, LLC v. DirecTV, Inc., 886 F.3d 375 (4th Cir. 2018), predicting how Delaware law would apply, suggested Delaware would recognize reverse veil-piercing especially readily against single-member entities used purely as asset-holding repositories. That's a federal court's prediction of Delaware law, not a Delaware state-court holding, but it's worth knowing about if your single-member LLC exists solely to hold assets rather than to run an active business.
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), maintain a written operating agreement even though it isn't required, keep basic records of major decisions and distributions, and adequately capitalize the LLC for the business it actually runs.
Can a Delaware Single-Member LLC Use a Series Structure?
Delaware pioneered the series LLC structure — 6 Del. C. § 18-215 has authorized series LLCs since 1996, longer than any other state. For a single-member owner running multiple properties or business lines, a Delaware series LLC can wall off each line's liability under one formation filing and one flat $300 annual tax — though banks and title companies in other states are still inconsistent about recognizing series structures internally, so confirm your specific use case works in practice before relying on one.
Does Delaware Have a Law Written Specifically for Single-Member LLCs?
Yes. 6 Del. C. § 18-703's "whether the limited liability company has 1 member or more than 1 member" language names single-member LLCs directly and guarantees them the same exclusive-remedy charging-order protection multi-member LLCs receive — one of the clearest examples of deliberate SMLLC-inclusive statutory drafting in this guide.
How Is a Delaware 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.
Delaware has a graduated personal income tax ranging from 2.2% up to a top marginal rate of 6.6% on income over $60,000. This applies to a Delaware-resident single-member LLC owner's pass-through profit in addition to federal income tax and self-employment tax — but a single-member LLC formed in Delaware and owned by an out-of-state resident who doesn't do business in Delaware generally owes no Delaware income tax at all, which is a major reason many out-of-state owners choose Delaware for holding-company structures.
Delaware LLCs owe a flat $300 annual tax, due June 1 each year, with no annual report required — just the flat payment. Late payment carries a $200 penalty plus 1.5% monthly interest. The flat, predictable amount (regardless of income or LLC size) is one of Delaware's most-cited administrative advantages.
Does My Delaware 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 bank (Delaware or otherwise) 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.
Sky Cable is a Fourth Circuit prediction of Delaware law, not a Delaware Court of Chancery or Delaware Supreme Court holding — so its ultimate reach for single-member holding LLCs remains somewhat unsettled, even though Delaware's core charging-order statute (§ 18-703) is squarely settled and explicit.
How to Set Up Your Delaware Single-Member LLC
If You Do It Yourself
Step 1 — File your Articles of Organization.
Form your LLC the same way any other Delaware LLC is formed — the state doesn't use a different form or process for single-member LLCs.
Step 2 — Appoint a registered agent.
Delaware 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.
No. 6 Del. C. § 18-101(7) defines a limited liability company agreement broadly as "any agreement...written, oral or implied," and expressly states an LLC "is not required to execute its limited liability company agreement" at all. Most single-member LLCs adopt a written agreement anyway, since Delaware courts will enforce whatever terms it contains with unusually broad deference to the parties' own drafting. An operating agreement can name a successor member and include transfer-on-death language, letting your LLC interest pass to an heir without going through Delaware probate — worth including even though Delaware doesn't require the document to exist in writing, or at all.
Step 4 — Understand your charging-order exposure.
Yes, explicitly and by name. 6 Del. C. § 18-703 states that a charging order is a judgment creditor's exclusive remedy, and that attachment, garnishment, foreclosure, and other remedies are unavailable "whether the limited liability company has 1 member or more than 1 member." Delaware was one of the first states to write single-member protection directly into its LLC statute rather than leaving the question to case law, which is part of why it's a common jurisdiction of choice for holding companies built from single-member LLCs.
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), maintain a written operating agreement even though it isn't required, 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 bank (Delaware or otherwise) 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.
Delaware LLCs owe a flat $300 annual tax, due June 1 each year, with no annual report required — just the flat payment. Late payment carries a $200 penalty plus 1.5% monthly interest. The flat, predictable amount (regardless of income or LLC size) is one of Delaware's most-cited administrative advantages. Delaware has a graduated personal income tax ranging from 2.2% up to a top marginal rate of 6.6% on income over $60,000. This applies to a Delaware-resident single-member LLC owner's pass-through profit in addition to federal income tax and self-employment tax — but a single-member LLC formed in Delaware and owned by an out-of-state resident who doesn't do business in Delaware generally owes no Delaware income tax at all, which is a major reason many out-of-state owners choose Delaware for holding-company structures.
Step 8 — Watch for Delaware-specific SMLLC traps.
The most common Delaware-specific mistake is assuming the flat $300 annual tax is the only ongoing state-level cost — owners who actually live in Delaware and run active operations there still owe Delaware personal income tax (up to 6.6%) on the LLC's pass-through profit, separate from the flat entity-level tax.

When Should You Talk to an Attorney About Your Delaware Single-Member LLC?

Frequently Asked Questions
Yes. 6 Del. C. § 18-703 explicitly states the charging order is the exclusive remedy against a member's interest "whether the limited liability company has 1 member or more than 1 member" — a deliberate statutory extension, one of the clearest and oldest of its kind in the country.
No, Delaware does not require a written operating agreement — 6 Del. C. § 18-101(7) confirms an LLC agreement can be oral or implied, and the LLC isn't even required to execute one. Most single-member LLCs still adopt a written agreement given how much deference Delaware courts give to its terms.
Delaware courts are notably reluctant to pierce the LLC veil, requiring something close to the entity existing solely as a vehicle for fraud. The main countervailing risk is reverse-veil-piercing exposure flagged in Sky Cable v. DirecTV for single-member LLCs used purely to hold assets rather than run an active business.
Yes. 6 Del. C. § 18-703's "whether...1 member or more than 1 member" language names single-member LLCs directly and confirms they receive the same exclusive-remedy charging-order protection as multi-member LLCs.
No. Partnership taxation requires at least two members. A Delaware single-member LLC can only be taxed as a disregarded entity (the default), or elect C-corp or S-corp taxation instead — the flat $300 annual Delaware tax applies regardless of which federal election you make.
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 bank requires it to open a business account, and it keeps your SSN off business paperwork.
Yes. Your operating agreement can name a successor member and include transfer-on-death language, letting your LLC interest pass to an heir outside of Delaware's probate process.
Because Delaware's charging-order statute already names single-member LLCs and extends the same exclusive-remedy protection multi-member LLCs receive, adding a nominal second member here wouldn't unlock protection you don't already have for charging-order purposes. It could still be worth discussing with an attorney if your specific concern is the Sky Cable reverse-piercing signal for pure asset-holding entities.
Yes. LLC Attorney forms single-member LLCs in Delaware, including a solo-owner operating agreement, starting at $0 + state fees.
