Hold multiple assets under one parent LLC with liability isolation between each series. One state filing, one annual report, one registered agent — unlimited internal series.

A Series LLC is a special type of limited liability company authorized under Wyoming Statute Section 17-29-1101 et seq. It allows a single parent LLC to create multiple internal "series," each of which can hold separate assets, incur separate liabilities, and have separate members or managers — all without forming separate legal entities with the state.
The defining characteristic of a Series LLC is internal liability segregation. If Series A holds a rental property and that property generates a lawsuit, the judgment creditor can only reach the assets of Series A. The assets in Series B, Series C, and the parent LLC itself are insulated from the claim — provided proper formalities are maintained.
Wyoming adopted Series LLC legislation following Delaware's model but with Wyoming's additional advantages: no public member/manager disclosure, single-member charging order protection, and no state income tax. The result is a structure that combines multi-asset liability protection with full anonymity.
Under Section 17-29-1101, a Wyoming LLC can establish one or more series by including a series designation in its Articles of Organization and providing for series in its operating agreement. Each series must maintain separate records and accounts. The statute requires that the assets associated with a series be held and accounted for separately from assets of any other series and the parent LLC.
The critical legal requirements for liability protection between series:
If these formalities are not maintained, a court could pierce the series separation and allow a creditor of one series to reach assets of another. This is the Series LLC equivalent of piercing the corporate veil.
The anonymity benefit of a Wyoming Series LLC is substantial. Only the parent LLC is filed with the Wyoming Secretary of State. The individual series are created internally through the operating agreement — they do not appear on any public state records.
This means a real estate investor holding ten rental properties through ten series of a single Wyoming Series LLC has one public entity on record. An outsider searching the Wyoming Secretary of State database sees one LLC with a registered agent. They cannot determine how many series exist, what assets each series holds, or who the members of any series are.
Compare this to forming ten separate LLCs: ten public filings, ten registered agents, ten annual reports, and ten sets of records that could be cross-referenced to identify a common owner pattern. The Series LLC eliminates this exposure entirely.
The most common and well-suited use case for a Wyoming Series LLC is real estate investment. An investor holding multiple rental properties faces liability from each property independently — tenant lawsuits, slip-and-fall claims, environmental issues, contractor disputes. Without liability segregation, a judgment against one property could threaten the equity in all properties.
With a Series LLC, each property is placed into its own series. Series A holds 123 Main Street. Series B holds 456 Oak Avenue. A tenant lawsuit arising from 123 Main Street is limited to the assets of Series A. The equity in 456 Oak Avenue and all other properties is protected.
Other common use cases include:

One of the primary advantages of a Series LLC is the ability to add new series without filing anything with the state. When you acquire a new property or want to segregate a new business line, the process is:
No state filing is required. No additional state fee. No additional annual report. The only state-level cost remains the single $60 annual report for the parent LLC regardless of how many series exist. This is where the cost savings versus multiple individual LLCs become dramatic.
The alternative to a Series LLC is forming a separate LLC for each asset. Both achieve liability isolation. Here is how they compare:
Cost comparison (5 assets, 3-year horizon)
Series LLC: $547 formation + ($60 annual report x 2 years) + ($49 RA x 2 years) = $765
5 individual LLCs: $397 x 5 formation + ($60 x 5 x 2 annual reports) + ($49 x 5 x 2 RA renewals) = $3,075
Administrative burden
Series LLC: 1 annual report, 1 registered agent, 1 set of state compliance deadlines. Individual LLCs: 5 of everything. Miss one annual report and that entity risks administrative dissolution.
Privacy
Series LLC: 1 public filing, impossible to determine number of series or assets. Individual LLCs: 5 public filings, possible to identify common registered agent and infer common ownership.
Legal certainty
Series LLC: Series statutes are newer and less court-tested. Cross-state enforcement is uncertain in states without series legislation. Individual LLCs: Traditional LLC liability protection is well-established in all 50 states.
The operating agreement for a Series LLC is more complex than a standard LLC operating agreement. It must address provisions specific to the series structure:
Anonymousllc.co provides a comprehensive series operating agreement that covers all statutory requirements under Section 17-29-1101. The agreement includes a template appendix for establishing new series so you can add series over time without redrafting the entire agreement.
Banking is one area where Series LLCs require careful attention. The parent LLC opens the primary bank account. Individual series should maintain separate bank accounts or, at minimum, separate sub-accounts with clear accounting. Commingling funds between series undermines the liability segregation that is the entire point of the structure.
Not all banks are familiar with Series LLCs. Some banks will open one account for the parent and allow you to maintain internal tracking. Others, particularly Mercury and Relay, may require explanation of the series structure during onboarding. Anonymousllc.co handles this communication during the bank application process and provides banks with the relevant operating agreement provisions.
For real estate investors, a practical approach is to open the parent bank account through the standard Anonymousllc.co process, then open additional accounts at local banks near each property as needed for series-specific operations (collecting rent, paying property management, etc.).
Not everyone needs a Series LLC. The structure adds complexity to your operating agreement, bookkeeping, and tax reporting. It is overkill in the following situations:

The IRS has provided guidance (Revenue Ruling 2008-8 for insurance-related series and proposed regulations in 2010) but has not issued final comprehensive regulations on series LLC taxation. The general consensus and IRS practice is that each series is treated as a separate entity for federal tax purposes. This means each series may need its own EIN and may need to file its own federal return depending on its membership structure.
In practice, many CPAs treat a single-member Series LLC (where all series have the same single member) as a single disregarded entity for simplicity. Multi-member series with different members in different series are clearly treated as separate entities. Consult a tax professional for your specific structure — this is an area where generic advice is insufficient.
There is no statutory limit on the number of series. You can create as many series as your business requires. Each new series is established through an operating agreement amendment, not a state filing.
No. Only the parent LLC appears on Wyoming Secretary of State records. Individual series are internal to the operating agreement and are not filed with or visible through any state database.
Yes. Each series can have its own members and managers independent of the parent LLC and other series. This allows joint ventures on individual assets while maintaining separate ownership of others.
No. As of 2026, approximately 20 states have Series LLC legislation. In states without series statutes, the liability segregation between series may not be recognized by local courts. If your assets are in a state without series legislation, research that state's treatment before relying on series protection.
