Indiana authorized the formation of series limited liability companies in 2016 under IC § 23-18.1-6. A series LLC is a single parent LLC that can create unlimited internal “series,” each with its own assets, liabilities, members, and managers—with a statutory liability shield between series. For real estate investors, this structure promises a way to hold multiple properties with isolated liability without forming and maintaining a separate LLC for each property. The promise is real, but so are the limitations that most promoters of series LLCs do not mention.
How an Indiana Series LLC Is Structured
The parent LLC is formed by filing Articles of Organization with the Indiana Secretary of State, with specific language establishing the authority to create series. Each series is then created under the operating agreement—not by a separate state filing. Each series can own property, enter contracts, sue and be sued, and grant security interests independently of the parent and other series. The operating agreement must document the assets and liabilities allocated to each series, and—critically—the records of each series must be maintained separately from the parent and from every other series.
The Liability Shield Between Series
Under IC § 23-18.1-6-4, the debts, liabilities, and obligations of one series do not become the debts, liabilities, and obligations of any other series or of the parent LLC, provided that the series maintains adequate records and separate accounts. This is the core value proposition: if a tenant is injured at Property A (held in Series A), a judgment against Series A cannot reach Property B (held in Series B) or the other assets of the parent LLC.
However, this liability shield is only as strong as the separation you maintain. If you commingle funds between series, fail to keep separate records, or treat the series as interchangeable, a court can disregard the liability barriers—just as it can pierce the corporate veil of a traditional LLC. The series structure demands more administrative discipline, not less.
The Myths That Get Investors in Trouble
Myth: A Series LLC Is Cheaper Than Multiple LLCs
On paper, you pay one filing fee to the Secretary of State and file one biennial report. But each series needs its own bank account, its own accounting records, and its own insurance policy or endorsement. Many banks will not open accounts for individual series within a series LLC, or will charge fees for each account. Many insurance carriers do not understand series LLCs or will not write policies that clearly allocate coverage by series. The administrative cost savings are smaller than promoters suggest.
Myth: Each Series Is Automatically Protected
The statutory shield exists only when the requirements of IC § 23-18.1-6-4 are met: separate records, separate accounting, and proper documentation in the operating agreement. Investors who create a series LLC and then run all properties through a single bank account with informal bookkeeping have no effective liability separation. The structure exists on paper but not in practice, and a creditor’s attorney will exploit that gap.
Myth: Series LLCs Are Recognized Everywhere
Indiana recognizes series LLCs, but not all states do. If you own property in a state that does not have a series LLC statute, a court in that state may not respect the liability barriers between your series. This is an unresolved area of law. Investors with properties in multiple states should consult an attorney about whether a series LLC provides adequate protection for out-of-state holdings.
When a Series LLC Makes Sense
A series LLC is best suited for Indiana real estate investors who hold multiple properties within Indiana, want liability isolation between properties, and are willing to maintain the administrative discipline required. The ideal candidate is an investor with 5 or more properties who would otherwise need to form and maintain 5 separate LLCs. For investors with 1–3 properties, the administrative burden of maintaining proper series separation may not justify the cost savings over individual LLCs.
When a Series LLC Does Not Make Sense
If you own properties in states that do not recognize series LLCs, if your bank or insurance carrier cannot accommodate the structure, or if you are not prepared to maintain rigorous separation between series, a traditional multi-LLC structure may provide more reliable protection. Additionally, if you plan to sell individual properties, the title transfer from a series within a series LLC can create complications that a standalone LLC avoids.
Frequently Asked Questions About Indiana Series LLCs
Does each series within a series LLC need its own EIN?
The IRS has not issued definitive guidance on the tax treatment of series LLCs. In practice, many accountants recommend that each series obtain its own EIN and file its own tax return, though some treat all series as a single entity for tax purposes. Your accountant and attorney should coordinate on the approach that best fits your situation.
Can I convert my existing LLC to a series LLC?
Yes, Indiana allows conversion of an existing LLC to a series LLC by amending the Articles of Organization and updating the operating agreement. However, existing contracts, loans, and insurance policies may need to be renegotiated or restructured, and any existing creditors retain their claims against the assets that were in the LLC at the time of conversion.
How does a series LLC affect property insurance?
Insurance is one of the most practical challenges with series LLCs. Each series should have its own policy or a clearly allocated endorsement under a master policy. Many carriers are unfamiliar with the structure and may not issue policies that explicitly protect individual series. Work with an insurance broker experienced with real estate investor structures before forming a series LLC.
Get the Structure Right from the Start
A series LLC can be an effective asset protection tool for Indiana real estate investors—but it is not a shortcut. The liability shield only works when the administrative requirements are followed, and the cost savings only materialize when your banking, insurance, and tax infrastructure can accommodate the structure.
