What an LLC Actually Protects (And What It Doesn't)

We formed our first LLC because someone told us it would protect our personal assets. That was true, and it was also not the whole story, and the part that was missing turned out to matter more than we expected.

The LLC liability protection is real. If the company is sued and a judgment is entered against it, a properly maintained LLC limits the plaintiff's recovery to the company's assets. Your personal bank account, your car, your house: these are not part of the company's assets and cannot be reached to satisfy a judgment against the company.

That protection disappears when specific things happen. None of those things are uncommon. All of them are things a new business owner might do without realizing the consequence.

What "piercing the corporate veil" means

Piercing the corporate veil is the legal term for a court disregarding the separation between the LLC and its owners and holding the owners personally liable for the company's obligations. Courts pierce the veil when they find that the separation between the person and the company was not real in practice, regardless of what the formation documents say.

The specific behaviors that lead to piercing are consistent across jurisdictions: commingling personal and business funds, failing to keep business records separate from personal records, undercapitalizing the company at formation (forming it without enough money to actually operate), using the company to commit fraud, and failing to follow the formalities that the operating agreement requires.

The last one is worth naming specifically. If your operating agreement requires member votes for major decisions, and you made major decisions without holding votes, a court can use that failure as evidence that the corporate form was not being respected. The operating agreement is not just a document you sign at formation. It is a description of how the company is supposed to operate, and departing from it creates exposure.

Why single-member LLCs are more vulnerable

A single-member LLC has one owner. The separation between the company and the owner is structural but thin. A plaintiff arguing for veil-piercing in a single-member LLC has an easier case to make: the owner and the company are the same person operating through different accounts. Courts in some jurisdictions apply stricter scrutiny to single-member LLC liability shields than they do to multi-member LLCs for this reason.

This does not mean a single-member LLC's liability protection is worthless. It means the behaviors that protect it, separate accounts, separate records, adequate capitalization, matters more in the single-member context. The protection is there if you maintain it. It is not automatic.

What the LLC form does not touch

A personal guarantee is not a company obligation. If you personally guarantee a lease, a loan, or a vendor contract, you are personally liable for that obligation regardless of the LLC structure. The guarantee exists alongside the entity. If the company cannot pay, the guarantor pays.

Professional liability in licensed fields operates differently than general business liability. In many states, licensed professionals (attorneys, physicians, CPAs, engineers) cannot limit their personal liability for professional negligence by operating through an LLC. Some states have specific entity types, professional LLCs or professional corporations, designed for this purpose with different rules. If you are a licensed professional, the standard LLC form may not provide the protection you expect for claims arising from your professional services.

Tax obligations flow through the company to the owners regardless of the liability protection for other purposes. If the company fails to pay payroll taxes, the IRS has specific authority to pursue "responsible persons" personally for the trust fund portion of those taxes. The LLC does not shield you from the IRS for payroll tax shortfalls.

What maintaining the protection requires

Open a business bank account and use it only for business transactions. Never deposit business income into a personal account, and never pay personal expenses from the business account. This is the most commonly violated rule and the most cited basis for a veil-piercing argument.

Keep the company's financial records separate from personal records: separate bookkeeping, separate tax filings, and treating the company as a distinct entity in every way that accounting and recordkeeping touch.

Capitalize the company adequately at formation. A company formed with $500 to its name and $500,000 of potential liability was undercapitalized, and undercapitalization is a factor courts look at when deciding whether to pierce.

The LLC is a tool. It does not protect you automatically. It protects you if you use it correctly, and using it correctly means behaving as if the company and you are genuinely different things, even when you are the only person in the room.
