Effective July 1, 2026, a single Florida limited liability company will be able to establish one or more protected series — sub-entities with their own members, managers, assets, and liabilities, each insulated from the debts of the parent LLC and the other series. For Florida real estate investors holding multiple properties through separate LLCs, family offices stacking investment vehicles, and operating businesses spinning up discrete product lines, this is the most consequential change to Florida entity law in more than a decade.
The structure is not new in principle — Delaware, Illinois, and a handful of other states have allowed series LLCs for years. What is new is Florida adopting the cleaner “protected series” framework that the Uniform Law Commission has been promoting, with explicit statutory horizontal liability shields and a defined records test. The drafting mechanics matter, and the firms that move first will set the precedent for how the statute is read.
What Changes on July 1
Three core changes take effect. First, a Florida LLC may form a protected series by complying with the statutory notice-and-recordkeeping requirements. Second, each protected series has horizontal liability shields: creditors of Series A cannot reach the assets of Series B, and vice versa, even though both share a parent LLC. Third, each protected series may have distinct economic rights, voting rights, members, and managers.
What does not change is equally important. A protected series is not a separate legal entity for all purposes — it is a sub-organization of the master LLC. Federal tax treatment is unchanged. Series-by-series filing obligations (franchise, sales tax, payroll) still apply where the activity warrants. And the horizontal liability shields depend on contemporaneous compliance with the recordkeeping requirements; sloppy bookkeeping defeats the structure.
When a Protected Series Beats the LLC Stack
We walked through the real estate use case recently, where a Northeast Florida investor with eight rental properties was evaluating the traditional stack of single-asset LLCs against the new protected series. The math comes out differently depending on scale and operational pattern.
The protected series tends to win when:
- The number of sub-entities is large. Annual filing fees and registered-agent costs compound across a stack. A protected series collapses those costs to a single master LLC.
- Sub-entities share operational infrastructure. One bookkeeper, one bank treasury platform, and one insurance broker servicing all series is materially cheaper than coordinating across a stack of separate entities.
- Sub-entities are similar in nature. Multiple single-family rentals, a portfolio of franchise units, or a series of investment fund vehicles work well in the series structure.
- The investor anticipates frequently adding new sub-entities. Spinning up a new protected series is faster and cheaper than incorporating a new LLC.
The traditional stack still wins when:
- Sub-entities have third-party investors with distinct economics. Outside capital still tends to prefer a familiar, fully-distinct LLC at the investment vehicle.
- Operations cross state lines. Series treatment is not uniform across states. A series with operations in a non-series-friendly state may face uncertain treatment.
- Lenders require a stand-alone entity. Mortgage and commercial lenders are still working out how to underwrite protected series. Many will not touch them yet.
- The sub-entity is being prepared for sale. Selling a single property or business line out of a protected series is mechanically more complicated than selling a single-asset LLC.
Drafting the Master Operating Agreement
The master operating agreement is the architectural document. It must (a) authorize the formation of protected series, (b) establish the general framework for series formation, governance, and dissolution, (c) define how the horizontal liability shields will be maintained, and (d) address tax allocation, fee allocation, and dispute resolution mechanics.
Five drafting moves we recommend on every master operating agreement we paper:
- Define the series-formation mechanic precisely. Specify how a series is created (a written designation document executed by the manager and recorded in the LLC’s books), what minimum information it must contain (name, manager, members, initial capital, scope of activity), and the effective date.
- Address the records test up front. The statutory liability shield requires that the LLC maintain records that account for the assets of each protected series separately from the other assets of the company or any other protected series. Specify exactly how that recordkeeping will be done — separate ledgers, separate bank accounts, separate tax allocation methodologies.
- Address the name convention. Statutory practice has converged on a naming pattern that identifies each series clearly (e.g., “Master LLC — Series A”). Use it consistently in contracts, deeds, financial statements, and tax filings.
- Allocate shared expenses with a defensible methodology. If the master LLC’s management fee is shared across all series, the allocation must be reasonable and applied consistently. Document the methodology in the operating agreement.
- Provide for series dissolution and asset distribution. A protected series can be dissolved without dissolving the master LLC. The operating agreement should specify the process and the priority of claims against the series’ assets.
The Records Test — What It Actually Means
The horizontal liability shield depends on continuous compliance with the statutory recordkeeping requirements. This is not a one-time setup; it is an operational discipline. Florida courts have not yet had occasion to interpret the new statute, but they will apply familiar veil-piercing logic where the records are sloppy. Delaware and Illinois case law on series records is the best available guide.
In practice, the records test means: each protected series should have its own bank account (or, at minimum, sub-account with clear ledger separation); each series should keep its own balance sheet and P&L; transactions between series should be documented as intercompany transfers with arms-length terms; and the master LLC should not commingle series assets to pay master-level expenses without a clear allocation methodology.
Pre-July-1 Entities and Conversion Paths
Existing Florida LLCs cannot retrofit themselves into protected series until the statute takes effect on July 1, 2026. After that date, conversion is possible but mechanically careful. Three paths are common.
Path 1: Restate the operating agreement. An existing LLC can adopt a restated operating agreement that authorizes protected series after July 1. Assets currently held by the LLC become master-level assets; new acquisitions can be allocated to newly-formed series.
Path 2: Form a new master and contribute. An investor with a stack of single-asset LLCs can form a new Florida LLC with master-series provisions and contribute the existing LLCs as series. The mechanical execution involves merger documents, lender consents, and title transfers; lender consents are typically the bottleneck.
Path 3: Wait and pre-position. Investors not under time pressure can paper the master operating agreement now (with effective date July 1, 2026), and execute the formation/contribution steps after the effective date. This path minimizes statutory risk.
Federal Tax Treatment
The IRS has historically treated each protected series as a separate entity for federal tax purposes when the series has separate ownership, separate assets, and separate business activity. Proposed regulations under Treas. Reg. § 301.7701-1 (issued in 2010, not yet finalized) point in that direction. In practice, this means each series files its own federal tax return (or is treated as a disregarded entity if single-member), pays its own tax, and is subject to its own audit. The federal classification is independent of the Florida statutory framework.
Practical Takeaways
- If you are a Florida real estate investor with five or more single-asset LLCs, the protected series structure likely saves you meaningful annual cost. Start the conversion analysis now.
- Paper the master operating agreement before July 1, 2026 with a forward-effective date. The conversion mechanics are smoother when the document is ready on day one.
- Get lender consents lined up before conversion. Most mortgage lenders have not yet developed a protected series underwriting framework; expect friction.
- Treat the records test as an operational discipline. Sloppy bookkeeping defeats the liability shield, and Florida courts will apply familiar veil-piercing logic.
- Do not assume federal tax treatment follows Florida law. Each series is generally a separate federal entity, with its own filings.
- For cross-state operations, evaluate the protected series in the most-restrictive state where the LLC will do business.

Frequently Asked Questions
When does the Florida Protected Series LLC framework take effect?
The framework takes effect July 1, 2026. Existing Florida LLCs can be restated to authorize protected series after that date; new master LLCs can be formed with protected series authorization on or after July 1, 2026.
How is a protected series different from a single-asset LLC?
A protected series is a sub-organization of a master LLC, not a separate legal entity. Multiple protected series share a single master LLC. Each series has its own members, managers, and assets, with statutory horizontal liability shields between series. A single-asset LLC is a distinct legal entity with its own filings and structure.
Will banks and lenders work with a Florida protected series?
Lender practice is still developing. As of 2026, many mortgage lenders and commercial banks have not yet finalized their underwriting approach to protected series. Expect friction. Investors planning to use the series structure should pre-clear the structure with their lenders before conversion.
How is a protected series taxed federally?
Each protected series is generally treated as a separate entity for federal tax purposes, consistent with proposed Treasury regulations. Each series files its own federal return (or is treated as a disregarded entity if single-member) and is subject to its own audit. The federal classification is independent of Florida state law.
Can I convert an existing stack of LLCs into protected series?
Yes, after July 1, 2026. Three paths are common: (1) restate the operating agreement of an existing LLC to authorize series, (2) form a new master LLC and contribute existing LLCs as series via merger or asset transfer, or (3) prepare paperwork now with a forward-effective date. Lender consents are typically the bottleneck.
