The #1 Mistake
The #1 Mistake People Make When Filing Their Own LLC
Forming an LLC feels like the finish line. You file the paperwork, get your approval, and suddenly you’re “official.” But here’s what almost nobody tells you: forming the LLC is only step one. The mistake we see over and over — one that quietly cancels out the entire point of having an LLC — happens after the paperwork is filed.
The mistake: mixing personal and business money
The single most common error we see is business owners who form an LLC, but never:
Get an EIN (Employer Identification Number) Open a separate business bank account Keep business expenses and personal expenses apart
On the surface, this seems harmless. You’re still “technically” an LLC, right? Unfortunately, it doesn’t work that way.
Why this matters: “piercing the corporate veil”
The entire reason people form an LLC is liability protection — the idea that if your business gets sued or goes into debt, your personal assets (your house, your car, your savings) stay protected because the business is a separate legal entity from you.
But that protection depends on you actually treating the LLC as separate. When a business owner pays personal bills from the business account, or deposits client payments into a personal account, courts can determine that the LLC isn’t functioning as a distinct entity at all — it’s just an extension of the individual. Legally, this is called piercing the corporate veil, and when it happens, the liability shield disappears. Creditors and plaintiffs can go after your personal assets exactly as if the LLC never existed.
In other words: you paid to form an LLC, but if your finances are tangled together, that LLC may not be protecting you at all.
The fix is simple — but it has to happen from day one
Protecting your LLC status doesn’t require anything complicated. It requires consistency:
Form your LLC properly, with all required state filings completed. Get your EIN right away — this is what allows you to open a business bank account and is required by the IRS for tax purposes, even if you have no employees. Open a dedicated business bank account and run every dollar of business income and expense through it — nothing personal. Keep records separate, including receipts, contracts, and invoices, in the business’s name, not your own.
That’s it. No accountant-level complexity required — just discipline about keeping the line clear between “you” and “the business.”
Why this trips up so many new business owners
Most people who run into this issue aren’t being careless — they simply didn’t know the rule existed. Online LLC formation services often file the paperwork and stop there, without explaining what has to happen after formation to keep the protection intact. That’s the gap that causes real problems down the line, usually right when a business owner needs that protection most: during a lawsuit, an audit, or a major debt dispute.
