Series LLC States: Full List - Anonymousllc.co's 2026 reference. Covers the rule, the controlling statute or regulation, common questions, and how Anonymousllc.co handles it in practice. Primary-source citations linked throughout.
A series LLC is a single parent LLC that can create internal cells - called series - each holding its own assets, members, and liability protection, so a lawsuit against one series does not reach the assets of another. It is a container structure for owners running several distinct ventures. The appeal is a liability firewall between cells without forming a separate LLC for each. A real estate investor can hold each property in its own series, and a creditor of one property cannot pursue the others, provided each series keeps separate records and bank accounts. Not every state authorizes series LLCs, and the ones that do vary on how each series is filed and taxed. Delaware pioneered the structure under 6 Del. C. § 18-215, and about twenty states plus the District of Columbia and Puerto Rico have followed.
About twenty states plus the District of Columbia and Puerto Rico authorize series LLCs. They include Delaware, Illinois, Texas, Nevada, Wyoming, Tennessee, Oklahoma, Utah, Iowa, Kansas, Missouri, Montana, North Dakota, Wisconsin, Alabama, Arkansas, Indiana, Nebraska, and Virginia. Delaware's statute (6 Del. C. § 18-215) is the oldest and most tested. Illinois and Texas are common choices because their statutes explicitly grant each series its own liability shield. Wyoming and Nevada added series provisions to their LLC Acts, which matters for owners who also want anonymity. States without a series statute do not offer the structure, so an owner in one of those states forms the series LLC in an authorizing state instead. The list changes as legislatures act, so verify against the current state statute before filing.
Three of the four anonymous states allow series LLCs: Wyoming, Delaware, and Nevada. New Mexico does not have a series LLC statute, so a series structure cannot be formed there. That overlap lets an owner combine two features - a liability firewall between cells and members kept off the public record. A Wyoming or Delaware series LLC can hold multiple ventures in separate series while the beneficial owner stays out of the state filing. For an owner who wants anonymity but not a series structure, New Mexico remains the lowest-cost anonymous state at $347 with no annual report. Anonymousllc.co matches the state to whether the series feature is actually needed.
A series LLC suits owners running multiple separable ventures - real estate investors with several properties, operators of distinct product lines, and holding-company structures. It is over-engineered for a single business with one revenue stream. Real estate is the classic use: each property sits in its own series, isolating the liability of one from the others without the cost of a separate LLC per property. The same logic fits a founder holding several brands or funds. A single-venture owner rarely needs it - one standard LLC delivers the same liability shield with simpler compliance. Anonymousllc.co forms standard anonymous LLCs in Wyoming, New Mexico, Delaware, and Nevada, and advises when a series structure is worth the added complexity.
The IRS treats each series as a separate entity for federal tax purposes under proposed regulations, so each cell files based on its own classification - disregarded entity, partnership, or corporate election. IRS Publication 3402 is the umbrella reference for LLC taxation. In practice, each series with its own members and activity is accounted for separately, and each may need its own EIN to bank and file. A single-owner series treated as a disregarded entity flows its income to the owner's return. State tax treatment of series LLCs varies, and some states tax the series as one entity while others follow the federal separate-entity approach. Anonymousllc.co routes the series tax questions to Alif Al Razi, who covers the classification detail.
Anonymity in a series LLC works the same way as in a standard anonymous LLC: the parent's members and managers stay off the public record, and only the registered agent appears on the state filing. The series cells are internal and not individually public. A Wyoming or Delaware series LLC keeps the beneficial owner out of the Articles, and the individual series are recorded in the private operating agreement rather than on state filings. The decision-maker remains the owner through the operating agreement, not the public record. Because New Mexico has no series statute, an owner wanting both a series structure and anonymity forms in Wyoming, Delaware, or Nevada. Anonymousllc.co forms the anonymous parent and structures the series internally.
Anonymousllc.co's flat pricing applies to the anonymous parent LLC: $397 all-in in Wyoming, $407 in Delaware, and $722 in Nevada - each a $297 service fee plus the state fee. New Mexico ($347) does not authorize series LLCs. Each price includes state filing, registered agent for year one, an operating agreement, an EIN, and 4-5 US bank applications. The full formation completes in 5-10 business days end-to-end, with the state accepting the filing in 1-3 days and the EIN following 5-7 days after. Add-ons are priced separately: EIN $99, ITIN $299, BOI initial filing $150, registered agent $100/year after year one. A series with its own bank account may need its own EIN, quoted per series.
Per the March 21, 2025 FinCEN interim final rule, domestic reporting companies are exempt from BOI filing, and a US-formed series LLC is a domestic entity. Foreign reporting companies remain obligated. Because the exemption came through an interim final rule rather than settled statute, an owner should verify the current requirement against the live rule rather than assume it. Anonymousllc.co's BOI Status Tracker shows the standing requirement. Where a foreign reporting company is involved, Anonymousllc.co files BOI reports at $150 each. For a domestic Wyoming, Delaware, or Nevada series LLC, no BOI filing is due under the current rule.
The most common series LLC mistakes are commingling assets across series, forming a series LLC when a standard LLC would do, and forming in a state that does not authorize series LLCs so the liability firewall between cells never legally exists. The firewall only holds if each series keeps separate records and separate bank accounts - commingle them, and a court can disregard the separation and expose every cell. Choosing a series structure for a single venture adds compliance cost with no benefit. Anonymousllc.co avoids these by confirming the series feature is needed, forming in an authorizing anonymous state - Wyoming, Delaware, or Nevada - and structuring separate records so each series holds its intended protection.
Anonymousllc.co forms the anonymous parent LLC in an authorizing state - Wyoming, Delaware, or Nevada - structures the series internally in the operating agreement, and files the EIN and bank applications. Start on WhatsApp and filing begins the same business day. Because New Mexico has no series statute, Anonymousllc.co matches the state to the feature set you actually need - series plus anonymity in the three authorizing states, or standard anonymity anywhere including New Mexico. The one-page quote states the exact state fee. The sister resources linked below cover the operating agreement that defines each series and the state fee charts, for owners verifying the structure and cost before they commit.
