Florida recognizes four practical LLC structures: single-member, multi-member, professional (PLLC), and series LLCs. The first two describe ownership and federal tax treatment, while the last two are distinct statutory structures created for specific purposes under Florida law.
A single-member LLC has one owner. Under the Florida Revised LLC Act (Chapter 605, Florida Statutes), a single-member LLC has the same liability protection and formation process as any other LLC. For federal tax purposes, the IRS treats a single-member LLC as a disregarded entity by default, meaning the owner reports business income directly on a personal return, unless the owner elects corporate taxation instead.
A multi-member LLC has two or more owners. Florida law governs it the same way it governs a single-member LLC, since Chapter 605 does not create separate entity categories based on ownership count. The distinction is primarily a federal tax matter: the IRS defaults a multi-member LLC to partnership taxation, with each member reporting a share of income and loss on a personal return, unless the members elect otherwise.
A professional LLC is organized for individuals licensed in fields such as law, medicine, accounting, or engineering. Under Section 621.051, Florida Statutes, a professional LLC is organized under the provisions of Chapter 605, but it operates under the added requirements of Chapter 621, the Professional Service Corporation and Limited Liability Company Act. Florida requires professional LLCs formed on or after January 1, 2014, to include a designation such as "PLLC" in the company name.
A series LLC allows a single Florida LLC to establish one or more internal "protected series," each with its own assets, liabilities, and members segregated from the others. This structure is authorized under Chapter 605, Part XXI, Florida Statutes (Sections 605.2101 through 605.2802). Florida's series LLC provisions, including the liability-shielding rule in Section 605.2103, took effect July 1, 2026, making this the newest of the four structures. Businesses considering a series LLC should confirm current filing procedures with the Florida Division of Corporations, since implementation guidance is still developing.
No. Florida law applies the same liability protection framework regardless of member count. The practical difference is in federal tax treatment and, in some other states, in how courts have treated single-member LLC asset protection in specific disputes.
Florida requires certain licensed professionals to form a PLLC rather than a standard LLC when organizing a professional practice. Confirm your specific licensing board's requirements before filing.
Florida's series LLC statute is newly effective as of July 1, 2026. Confirm current eligibility and filing requirements with the Florida Division of Corporations or a Florida business attorney before relying on this structure.
