Key Takeaways
- Colorado does NOT clearly extend charging-order-as-exclusive-remedy protection to single-member LLCs — In re Albright, 291 B.R. 538 (Bankr. D. Colo. 2003)
- Colorado does not legally require a written operating agreement, but you should have one anyway
- Colorado is one of the two or three most commonly cited cautionary states in asset-protection literature for single-member LLCs, and for good reason. Martin v. Freeman, 2012 COA 22 (Colo. App. 2012), held that a court can reach a single-member LLC's assets without even showing fraud or bad faith — a materially lower bar than the standard veil-piercing test, which normally requires some showing of wrongdoing. Sedgwick Properties Development Corp. v. Hinds, 2019 COA 102 (Colo. App. 2019) reaffirmed a three-part alter-ego test in a case that again involved a single-member-type entity. Combined with Albright's bankruptcy-context erosion of charging-order protection, Colorado is genuinely one of the more unfavorable states in this guide for single-member LLC asset protection — this is case-law-based exposure, not a statutory gap, so it can't be fixed by amending your operating agreement alone.
- Colorado has a flat personal income tax of approximately 4.25%–4.40% (the exact rate can shift slightly year to year based on state revenue triggers under TABOR), so a single-member LLC owner pays that rate on the LLC's pass-through profit in addition to federal income tax and federal self-employment tax.

A single-member LLC is the most common way solo owners in Colorado structure their business — but Colorado is also one of the most commonly cited cautionary states in asset-protection literature, thanks to two separate rulings, In re Albright and Martin v. Freeman, that both weaken the protection a single owner gets compared to a multi-member LLC.
This guide covers exactly how a Colorado single-member LLC works in 2026 — the Albright charging-order gap, Martin v. Freeman's lowered alter-ego bar, whether you need a written operating agreement, and how the LLC is taxed at both the federal and state level.
What Is a Colorado 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 Colorado 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 Colorado 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 this is Colorado's most important SMLLC quirk. C.R.S. § 7-80-703 makes the charging order exclusive on its face, with no statutory carve-out for single-member LLCs. But In re Albright, 291 B.R. 538 (Bankr. D. Colo. 2003) held that "the charging order limitation serves no purpose in a single member limited liability company" because there are no other members' interests to protect — the bankruptcy trustee was permitted to step directly into the sole member's shoes and liquidate the LLC's assets. Albright is a U.S. Bankruptcy Court ruling (a bankruptcy-trustee context, not a Colorado state-court decision), but it remains the most widely cited case nationally for the proposition that charging-order protection may not meaningfully protect single-member LLCs, and Colorado courts have not repudiated its reasoning.
Do I Need an Operating Agreement for My Colorado SMLLC?
No — C.R.S. § 7-80-102 states the LLC agreement "need not be in writing." Given Albright and Martin v. Freeman, a well-drafted written operating agreement is worth considerably more in Colorado than in most states, since it's part of the evidence a court will look at when deciding whether the LLC is a genuinely separate entity.
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 Colorado probate — worth including even though Colorado doesn't require the document itself.
Is a Colorado 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.
Colorado is one of the two or three most commonly cited cautionary states in asset-protection literature for single-member LLCs, and for good reason. Martin v. Freeman, 2012 COA 22 (Colo. App. 2012), held that a court can reach a single-member LLC's assets without even showing fraud or bad faith — a materially lower bar than the standard veil-piercing test, which normally requires some showing of wrongdoing. Sedgwick Properties Development Corp. v. Hinds, 2019 COA 102 (Colo. App. 2019) reaffirmed a three-part alter-ego test in a case that again involved a single-member-type entity. Combined with Albright's bankruptcy-context erosion of charging-order protection, Colorado is genuinely one of the more unfavorable states in this guide for single-member LLC asset protection — this is case-law-based exposure, not a statutory gap, so it can't be fixed by amending your operating agreement alone.
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 — all of this matters more in Colorado given Martin v. Freeman's lowered bar for reaching a single-member LLC's assets.
How Is a Colorado 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.
Colorado has a flat personal income tax of approximately 4.25%–4.40% (the exact rate can shift slightly year to year based on state revenue triggers under TABOR), so a single-member LLC owner pays that rate on the LLC's pass-through profit in addition to federal income tax and federal self-employment tax.
Colorado LLCs owe a Periodic Report, $25 (raised from $10 effective July 1, 2024 per SB 23-276), due in a five-month window centered on the LLC's anniversary month — a flat filing fee, not an income-based tax, and it applies regardless of whether the LLC made any profit.
Does My Colorado 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 Colorado 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.
In re Albright is a federal bankruptcy court decision applying Colorado law in a bankruptcy-trustee context, not a Colorado state appellate ruling, so a future Colorado state court could theoretically decline to follow its reasoning — but Martin v. Freeman is a Colorado Court of Appeals decision and remains good law as of 2026. Treat both as controlling the practical asset-protection analysis until a higher Colorado court says otherwise.
How to Set Up Your Colorado Single-Member LLC
If You Do It Yourself
Step 1 — File your Articles of Organization.
Form your LLC the same way any other Colorado LLC is formed — the state doesn't use a different form or process for single-member LLCs.
Step 2 — Appoint a registered agent.
Colorado 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 — C.R.S. § 7-80-102 states the LLC agreement "need not be in writing." Given Albright and Martin v. Freeman, a well-drafted written operating agreement is worth considerably more in Colorado than in most states, since it's part of the evidence a court will look at when deciding whether the LLC is a genuinely separate entity. 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 Colorado probate — worth including even though Colorado doesn't require the document itself.
Step 4 — Understand your charging-order exposure.
No — and this is Colorado's most important SMLLC quirk. C.R.S. § 7-80-703 makes the charging order exclusive on its face, with no statutory carve-out for single-member LLCs. But In re Albright, 291 B.R. 538 (Bankr. D. Colo. 2003) held that "the charging order limitation serves no purpose in a single member limited liability company" because there are no other members' interests to protect — the bankruptcy trustee was permitted to step directly into the sole member's shoes and liquidate the LLC's assets. Albright is a U.S. Bankruptcy Court ruling (a bankruptcy-trustee context, not a Colorado state-court decision), but it remains the most widely cited case nationally for the proposition that charging-order protection may not meaningfully protect single-member LLCs, and Colorado courts have not repudiated its reasoning.
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 — all of this matters more in Colorado given Martin v. Freeman's lowered bar for reaching a single-member LLC's assets.
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 Colorado 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.
Colorado LLCs owe a Periodic Report, $25 (raised from $10 effective July 1, 2024 per SB 23-276), due in a five-month window centered on the LLC's anniversary month — a flat filing fee, not an income-based tax, and it applies regardless of whether the LLC made any profit. Colorado has a flat personal income tax of approximately 4.25%–4.40% (the exact rate can shift slightly year to year based on state revenue triggers under TABOR), so a single-member LLC owner pays that rate on the LLC's pass-through profit in addition to federal income tax and federal self-employment tax.
Step 8 — Watch for Colorado-specific SMLLC traps.
The most common Colorado-specific mistake is assuming an LLC (of any member count) automatically gets the same charging-order protection multi-member LLCs enjoy elsewhere — In re Albright specifically reasoned that charging-order protection "serves no purpose" for a single-member LLC, and Martin v. Freeman lets a Colorado court reach a single-member LLC's assets without even showing fraud or bad faith.

When Should You Talk to an Attorney About Your Colorado Single-Member LLC?
Talk to an attorney before finalizing your Colorado single-member LLC's structure if asset protection from personal creditors or potential bankruptcy exposure is a primary goal (Albright and Martin v. Freeman both materially weaken the default protection here), if you're deciding whether to add a nominal second member specifically to move outside these single-member-focused rulings, or if you're holding significant assets in the LLC and want your formalities and operating agreement reviewed given Martin v. Freeman's lowered bar for reaching single-member LLC assets.
Is Colorado a State Where SMLLC Asset Protection Matters More?
Colorado is one of the more consequential states in this guide for a single-member LLC owner specifically because two separate lines of case law — In re Albright on charging orders and Martin v. Freeman on alter-ego liability — both work against single-member LLCs in ways that don't apply to multi-member LLCs. If asset protection is a primary reason you're forming an LLC, Colorado's default posture is one of the weaker ones in this guide and is worth understanding clearly before you rely on it.
What You Actually Get With LLC Attorney's Colorado SMLLC Formation

Frequently Asked Questions
Formally yes under C.R.S. § 7-80-703's plain text, but In re Albright, 291 B.R. 538 (Bankr. D. Colo. 2003) held that charging-order protection "serves no purpose" for a single-member LLC and let a bankruptcy trustee liquidate the LLC's assets directly — a federal bankruptcy ruling, not a Colorado state-court decision, but the most widely cited authority on this exact issue nationally.
No, Colorado does not legally require a written operating agreement for a single-member LLC — C.R.S. § 7-80-102 says it "need not be in writing." Given Albright and Martin v. Freeman, a written operating agreement is worth more in Colorado than in most states as evidence your LLC is genuinely separate from you personally.
Yes, more so than in most states. Martin v. Freeman, 2012 COA 22 (Colo. App. 2012), held that a Colorado court can reach a single-member LLC's assets without even showing fraud or bad faith — a materially lower bar than standard veil-piercing. Keeping clean formalities matters more here than almost anywhere else in this guide.
No. Colorado's exposure for single-member LLCs comes entirely from case law (In re Albright and Martin v. Freeman) rather than from any statute written specifically for single-owner companies — the underlying LLC Act applies the same text to single- and multi-member LLCs alike.
No. Partnership taxation requires at least two members. A Colorado single-member LLC can only be taxed as a disregarded entity (the default), or elect C-corp or S-corp taxation instead — Colorado's flat income tax follows whichever 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 Colorado 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 Colorado's probate process — even though Colorado doesn't require the operating agreement itself.
Some Colorado single-member LLC owners do add a nominal second member (often a spouse or family trust) specifically because both In re Albright and Martin v. Freeman turned on the entity having only one member — adding a genuine second member changes that fact pattern. This has real tradeoffs — a second member changes tax treatment and governance — so it's worth discussing with an attorney rather than doing informally.
Yes. LLC Attorney forms single-member LLCs in Colorado, including a solo-owner operating agreement, starting at $0 + state fees.
