Series LLC Explained: One Entity, Multiple Properties

If you own multiple rental properties or investment assets, you have probably been told to create a separate LLC for each one. That provides liability isolation — if a tenant sues over Property A, Property B is protected. But managing five, ten, or twenty separate LLCs is a compliance nightmare. Enter the Series LLC.

What Is a Series LLC?

A Series LLC is a single LLC that can create multiple "series" (sometimes called "cells"), each functioning as a separate legal entity within the parent LLC. Each series can:

• Own separate assets
• Have separate liabilities
• Have different members and managers
• Enter into contracts independently

Crucially, the liabilities of one series do not cross over to another series or to the parent LLC. If Series A (holding Property A) gets sued, the assets in Series B (holding Property B) are protected.

Which States Allow Series LLCs?

Not all states recognize the Series LLC structure. States that currently allow formation of Series LLCs include:

• Delaware (the pioneer)
• Illinois
• Texas
• Nevada
• Iowa
• Oklahoma
• Tennessee
• Utah
• Wyoming (added in recent years)

However, a major caveat: states that do not have Series LLC laws may not recognize the liability separation between series. If you own property in a state that does not recognize Series LLCs, the liability protection between series is uncertain.

Advantages Over Multiple LLCs

• One filing fee. You pay one state filing fee for the parent LLC, not one per series.
• One annual report. One filing instead of many.
• One registered agent. One fee instead of ten.
• Simplified administration. One operating agreement (with series-specific addenda) instead of separate agreements for each entity.

Disadvantages and Risks

• Uncertain cross-state recognition. If your Series LLC is in Delaware but your property is in Georgia, Georgia courts may not honor the series separation.
• Tax complexity. The IRS has not issued definitive guidance on how Series LLCs should be taxed. Most practitioners treat each series as a separate entity for tax purposes, but this adds complexity.
• Banking challenges. Some banks are unfamiliar with Series LLCs and may require separate accounts and EINs for each series.
• Limited case law. There are very few court cases testing Series LLC liability protection. The structure is relatively new and largely untested in litigation.

The Alternative: Holding Company Structure

Many real estate investors opt for a traditional holding company structure instead: one parent LLC that owns separate child LLCs, each holding one property. This is more expensive to set up and maintain, but the liability separation is well-established in every state.

Should You Use a Series LLC?

A Series LLC can be a cost-effective solution for investors with multiple assets in states that recognize the structure. But the legal uncertainty means you should consult with an attorney before relying on series separation for liability protection, especially for properties in non-Series-LLC states.
