Maria launched a Jacksonville home-staging business and formed her LLC herself on Sunbiz in an afternoon. She listed her condo as the registered agent address, left the company member-managed without thinking about it, and never put her sixty-forty split with her silent-partner brother in writing. A year later she moved. She missed the annual report and a lawsuit that was served to the old address, her LLC was administratively dissolved, and she found herself personally exposed on a vendor claim and in an argument with her brother over what he actually owned.
None of that was caused by the filing. It was caused by the decisions no one made before the filing. Forming a Florida LLC is deliberately easy — the state wants businesses to form — but easy is not the same as right. After 30 years of setting these up and cleaning them up, these are the six decisions that decide whether your LLC protects you or just exists on paper.
1. The Name — and Whether You Can Actually Use It
Your LLC name has to be distinguishable from every other entity on file with the Florida Division of Corporations and must include a proper designator ("LLC" or "L.L.C."). Searching Sunbiz for an exact match is the easy part. The part people skip is checking whether the name collides with a registered trademark or a brand already operating in your market — a clear Sunbiz search does not clear you under trademark law.
Decide early whether the legal name and the brand you market under are the same. If they differ, you will likely need a fictitious name ("doing business as") registration. Picking the name is also the moment to grab the matching domain and handles before you commit — changing a name after you have printed cards, signed contracts, and opened accounts is its own small project.
2. The Registered Agent and a Durable Address
Every Florida LLC must name a registered agent with a physical Florida street address who is available during business hours to receive legal process and state notices. You can serve as your own agent, and plenty of owners do. The hidden risk is not who the agent is — it is whether the address stays current.
This is exactly where Maria's LLC failed. A registered agent address that goes stale means a served lawsuit or a state notice lands somewhere you no longer are. Miss a served complaint and a default judgment can be entered against the company without you ever seeing the papers. Miss enough notices and the state administratively dissolves the entity, which can erase the very liability shield you formed the LLC to get. If you move often, a commercial registered agent service is cheap insurance.
3. Member-Managed or Manager-Managed
The Articles of Organization ask you to choose a management structure, and most DIY filers click "member-managed" without weighing it. In a member-managed LLC, every owner can act for and bind the company. In a manager-managed LLC, authority sits with designated managers — who may be owners, outside professionals, or a mix — and passive owners do not have day-to-day authority.
The choice matters the moment there is an investor who writes checks but should not sign contracts, or a silent partner like Maria's brother. If the structure on the filing does not match how the company actually runs — and does not match the operating agreement — you get exactly the ambiguity that produces disputes over who was allowed to do what. Decide who holds authority before you file, not after someone exercises it.
4. Ownership and Capital — in Writing
The single most expensive thing founders leave undocumented is who owns what and what stands behind it. Write down each member's ownership percentage, the capital each one actually contributed (cash, equipment, or property), and whether the company can require more money later through a capital call. When one member contributes work instead of cash, or the contributions are unequal, this is the provision that either prevents a future fight or creates one.
Maria and her brother "agreed" on sixty-forty, but it lived only in a text thread and their memories, which had diverged by the time money was at stake. Ownership economics settled on a handshake are ownership economics you will relitigate. Settle the split, the contributions, and the capital-call mechanics while everyone still likes each other.
5. Tax Classification and the EIN
An LLC is a state-law entity; the IRS does not have an "LLC" tax box. By default a single-member LLC is taxed as a sole proprietorship and a multi-member LLC as a partnership, with income passing through to the owners. An LLC can also elect to be taxed as an S corporation, which can reduce self-employment tax once the business clears a certain level of profit — but it adds payroll and filing obligations that are not worth it for a brand-new venture.
You do not have to solve this perfectly before you file, but decide the starting point and get your EIN from the IRS right after formation so you can open a dedicated business bank account. That separate account is not a formality — commingling personal and company money is one of the fastest ways to undermine the liability protection the LLC is supposed to give you. Coordinate the election with your CPA; this is a place where tax and legal decisions touch.
6. The Operating Agreement You Think You Do Not Need
Florida does not require an operating agreement and does not file one with the state. That is exactly why so many companies end up governed by the default rules of Chapter 605 of the Florida Statutes — rules the owners never chose and usually never read. The operating agreement is where decisions one through five get captured and where the questions that wreck companies get answered in advance: what happens on a deadlock, when a member dies, when someone wants to sell their interest to an outsider.
Even a single-member LLC benefits from a short one, because it documents the separateness between you and the company that a court looks for if anyone ever tries to pierce the veil.

The Pattern Worth Remembering
Maria's LLC was never the problem. The afternoon on Sunbiz worked fine. What failed were the six decisions that the filing form does not force you to make well: a name she could keep, an address that would follow her, a management structure that matched her partner, an ownership split in writing, a tax and banking setup that kept the money separate, and an operating agreement that answered the hard questions before they arrived.
A truly simple single-member LLC with no investors and no unusual economics can be a genuine do-it-yourself project. Once there is a second owner, unequal contributions, outside money, or a real business at stake, these six decisions are the work — and they are far cheaper to get right at formation than to unwind after a dispute, a lawsuit, or an administrative dissolution.
