--- title: "Connecticut Single-Member LLC: Charging Order Protection & Taxes 2026 | LLC Attorney" description: "How a single-member LLC works in Connecticut in 2026: the explicit 'one member or more than one member' statutory language, operating agreement rules, and taxes." canonical: https://llcattorney.com/states/ct/single-member-llc-connecticut image: https://llcattorney.com/images/share-cover.png source_path: /states/ct/single-member-llc-connecticut --- Key Takeaways - Connecticut extends charging-order-as-exclusive-remedy protection to single-member LLCs the same as multi-member LLCs — Conn. Gen. Stat. § 34-259b (whether one member or more than one member) - Connecticut does not legally require a written operating agreement, but you should have one anyway - Connecticut applies standard instrumentality and identity tests for veil-piercing, without a confirmed Connecticut LLC case applying heightened scrutiny specifically to single-member LLCs. (A case sometimes cited in this context, Naples v. Keystone Building & Development Corp., 295 Conn. 214 (2010), appears to involve a corporation rather than an LLC, so it shouldn't be relied on as direct single-member LLC precedent.) As with any single-member entity, there's no second owner's independent conduct to point to as evidence the company is genuinely separate, which is why formalities matter in practice even without a specific unfavorable ruling on the books. - Connecticut has a graduated personal income tax ranging from 2% up to a top marginal rate of 6.99%, 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. - Yes. Conn. Gen. Stat. § 34-259b explicitly states its charging-order-exclusivity rule applies "whether the limited liability company has one member or more than one member" — a deliberate, named statutory extension to single-member LLCs, not a generic charging-order provision that merely happens to be silent on the issue. - Same-day single-member LLC formation and a solo-owner operating agreement available through LLC Attorney, at no markup on state fees A single-member LLC is the most common way solo owners in Connecticut structure their business — and Connecticut is one of a small number of states that wrote explicit, named single-member charging-order protection directly into its statute. This guide covers exactly how a Connecticut single-member LLC works in 2026 — the § 34-259b "one member or more than one member" language, whether you need a written operating agreement, alter-ego risk, and how the LLC is taxed at both the federal and state level.

A single-member LLC (SMLLC) is a limited liability company with exactly one owner. It's formed the same way as any other Connecticut 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 Connecticut 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. Conn. Gen. Stat. § 34-259b makes the charging order the exclusive remedy against a member's interest, and the statute states that other remedies — attachment, garnishment, foreclosure — "are not available to the judgment creditor, whether the limited liability company has one member or more than one member." This language was enacted via Public Act 16-97, effective July 1, 2017, specifically to remove any ambiguity about single-member LLCs, putting Connecticut in the same flagship-tier protective category as Delaware. ## Do I Need an Operating Agreement for My Connecticut SMLLC? No. Connecticut does not require a written operating agreement, and it doesn't need to be filed with the state even if you have one. It's still worth putting in writing given how much weight courts generally place on a clear, contemporaneous operating agreement when evaluating whether an LLC is being run as 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 Connecticut probate — worth including even though Connecticut doesn't require the document itself. ## Is a Connecticut 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. Connecticut applies standard instrumentality and identity tests for veil-piercing, without a confirmed Connecticut LLC case applying heightened scrutiny specifically to single-member LLCs. (A case sometimes cited in this context, Naples v. Keystone Building & Development Corp., 295 Conn. 214 (2010), appears to involve a corporation rather than an LLC, so it shouldn't be relied on as direct single-member LLC precedent.) As with any single-member entity, there's no second owner's independent conduct to point to as evidence the company is genuinely separate, which is why formalities matter in practice even without a specific unfavorable ruling on the books. **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. ## Does Connecticut Have a Law Written Specifically for Single-Member LLCs? Yes. Conn. Gen. Stat. § 34-259b explicitly states its charging-order-exclusivity rule applies "whether the limited liability company has one member or more than one member" — a deliberate, named statutory extension to single-member LLCs, not a generic charging-order provision that merely happens to be silent on the issue. ## How Is a Connecticut 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. Connecticut has a graduated personal income tax ranging from 2% up to a top marginal rate of 6.99%, 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. Connecticut LLCs owe an Annual Report, $80, due between January 1 and March 31 each year, filed with the Secretary of the State — a flat filing fee, not an income-based tax, and it applies regardless of whether the LLC made any profit. ## Does My Connecticut 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 Connecticut 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. ## How to Set Up Your Connecticut Single-Member LLC ### If You Do It Yourself **Step 1 — File your Articles of Organization.** Form your LLC the same way any other Connecticut LLC is formed — the state doesn't use a different form or process for single-member LLCs. **Step 2 — Appoint a registered agent.** Connecticut 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. Connecticut does not require a written operating agreement, and it doesn't need to be filed with the state even if you have one. It's still worth putting in writing given how much weight courts generally place on a clear, contemporaneous operating agreement when evaluating whether an LLC is being run as 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 Connecticut probate — worth including even though Connecticut doesn't require the document itself. **Step 4 — Understand your charging-order exposure.** Yes, explicitly and by name. Conn. Gen. Stat. § 34-259b makes the charging order the exclusive remedy against a member's interest, and the statute states that other remedies — attachment, garnishment, foreclosure — "are not available to the judgment creditor, whether the limited liability company has one member or more than one member." This language was enacted via Public Act 16-97, effective July 1, 2017, specifically to remove any ambiguity about single-member LLCs, putting Connecticut in the same flagship-tier protective category as Delaware. **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 Connecticut 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.** Connecticut LLCs owe an Annual Report, $80, due between January 1 and March 31 each year, filed with the Secretary of the State — a flat filing fee, not an income-based tax, and it applies regardless of whether the LLC made any profit. Connecticut has a graduated personal income tax ranging from 2% up to a top marginal rate of 6.99%, 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 Connecticut-specific SMLLC traps.** The most common Connecticut-specific mistake is not realizing how strong the state's statutory language actually is — owners sometimes assume they need to add a second member or take other steps to "protect" their single-member LLC's charging-order status, when § 34-259b already extends that protection explicitly by statute.

Conn. Gen. Stat. § 34-259b explicitly states the charging order is the exclusive remedy against a member's interest "whether the limited liability company has one member or more than one member" — a deliberate statutory extension, not a gap that happens to work in solo owners' favor. ### Is a written operating agreement legally required for a Connecticut single-member LLC? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) No, Connecticut does not legally require a written operating agreement for a single-member LLC, and it doesn't need to be filed with the state even if one exists. It's still worth putting in writing as evidence of a genuinely separate, deliberately operated entity. ### Are Connecticut single-member LLCs at greater risk of having their liability shield pierced? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) Connecticut applies standard instrumentality and identity veil-piercing tests without a confirmed case singling out single-member LLCs for heightened scrutiny. Keeping clean formalities still matters, since a solo owner has no second member's conduct to point to as evidence the company is genuinely separate. ### Does Connecticut have a law written specifically for single-member LLCs? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) Yes. Conn. Gen. Stat. § 34-259b names single-member LLCs directly, confirming the exclusive-remedy charging-order rule applies "whether the limited liability company has one member or more than one member." ### Can a single-member LLC in Connecticut elect partnership taxation? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) No. Partnership taxation requires at least two members. A Connecticut single-member LLC can only be taxed as a disregarded entity (the default), or elect C-corp or S-corp taxation instead — Connecticut's graduated income tax follows whichever federal election you make. ### Does a single-member LLC in Connecticut need an EIN? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) 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 Connecticut bank requires it to open a business account, and it keeps your SSN off business paperwork. ### Can a Connecticut single-member LLC's operating agreement help my heirs avoid probate? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) 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 Connecticut's probate process — even though Connecticut doesn't require the operating agreement itself. ### Should I add a second member to my Connecticut LLC just to get better asset protection? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) Because Connecticut'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 — it would mainly change your tax treatment and governance. Most Connecticut single-member LLC owners don't need to add a second member purely for asset-protection reasons. ### Does LLC Attorney form single-member LLCs? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) Yes. LLC Attorney forms single-member LLCs in Connecticut, including a solo-owner operating agreement, starting at $0 + state fees. ## Related Connecticut Resources - [Connecticut LLC Formation](/states/ct/llc-formation-connecticut) - [Connecticut Registered Agent](/states/ct/registered-agent-connecticut) - [Connecticut EIN Number](/states/ct/ein-number-connecticut)
