A skincare founder I'll call Priya built a fast-growing e-commerce brand out of Jacksonville. Two years earlier she had filed a single-member LLC through a $99 online service, never adopted an operating agreement, and routinely paid personal expenses straight from the business account. When a supplier sued over a disputed order, their lawyer did not just sue the LLC. They came after Priya personally, arguing the company was her alter ego. The commingled bank records were the entire case against her.
That is what a pierced veil looks like in practice. The LLC did its job at formation — it just stopped doing its job because the owner stopped treating it as a separate entity. A Florida LLC is not a one-time purchase. It is a discipline. Here are the five mistakes that hand a creditor the keys to your personal assets, and how to close each one.
1. Commingling Personal and Business Money
This is the mistake that pierces more veils than all the others combined. The moment you pay a personal credit card, a car note, or a grocery run out of the business account — or deposit business revenue into your personal checking — you have given a creditor the single best argument they have: there is no real separation between you and the company.
Florida courts applying the alter-ego doctrine look first at the money. If the LLC's bank account is functionally the owner's second wallet, the entity is a fiction and the court can disregard it. The fix is mechanical and free: a dedicated business bank account, a dedicated business card, and a clean paper trail. When you need money out of the company, take it as a documented owner draw or salary — never as a casual swipe.
2. Skipping the Operating Agreement
Florida does not require you to file an operating agreement to form an LLC, which is exactly why so many owners skip it. But the absence of one is affirmative evidence in a veil-piercing fight. It tells the court the owner never bothered to treat the LLC as a separate, governed entity with its own rules.
An operating agreement does the structural work: it documents that the company exists apart from you, defines how decisions and distributions happen, and — for single-member LLCs especially — establishes the formalities that prove the entity is real. It is one of the cheapest forms of asset protection on the menu. I wrote more about what happens when there isn't one in what happens to a Florida LLC with no operating agreement.
3. Signing Contracts in Your Own Name
The LLC can only protect you on deals the LLC actually entered. When you sign a vendor agreement, a lease, or a purchase order as "Priya Sharma" instead of "Priya Sharma, Member, Sharma Skincare LLC," you have personally bound yourself to that contract. The liability shield never attaches because the other side contracted with you, not the company.
Every signature on behalf of the business must name the entity and your capacity. The format is simple: the LLC's full legal name, then your name, then your title (Member or Manager). Get this wrong even once on a six-figure agreement and the entity protection is irrelevant for that deal.
4. Undercapitalizing the LLC
An LLC formed with no meaningful capital — no initial contribution, no operating reserve, nothing in the account — looks to a court like a shell built to hold liabilities while the owner keeps the assets safely outside. Chronic undercapitalization is one of the recognized factors Florida courts weigh when deciding whether to pierce the veil.
You do not need a fortune. You need a documented initial capital contribution and enough working capital for the business to actually meet its obligations. Record the contribution in the operating agreement and the company's books. A business that is funded to do its job does not look like a sham, and that perception matters when a creditor is hunting for personal assets.
5. Letting the LLC Lapse
Florida requires every LLC to file an annual report with the Division of Corporations and maintain a registered agent at a physical Florida address. Miss the annual report and the state administratively dissolves the company. An owner who keeps operating after dissolution may be personally liable for obligations incurred while the LLC was not in good standing — the shield is simply gone.
The annual report is due by May 1 each year, with a steep late fee that the statute does not let the state waive. Calendar it, keep your registered agent current, and confirm your status on Sunbiz once a year. This is the easiest of the five to fix and the one owners most often forget.
The Shield Is Maintenance, Not a Purchase
Notice what these five mistakes have in common: none of them are about how you filed the LLC. They are about how you run it afterward. A creditor piercing the veil is not attacking your formation paperwork — they are pointing to your behavior and saying the company was never really separate from you.
That is good news, because every one of these is within your control. Separate the money, sign the operating agreement, contract in the entity's name, fund the business honestly, and keep it in good standing. Do those five things and the protection you paid for at formation actually holds when you need it. If you want the formation and operating agreement done right from the start, that is exactly what the firm's flat-fee work covers — and you can read what every Florida LLC owner should know for the foundational picture.
