What single-member LLC liability protection actually covers

Less than most people think, and it stops in places that matter.

What it does

Generally separates the company's obligations from your personal assets. If the company owes a vendor and can't pay, the vendor generally can't reach your house.

That's real and it's worth having.

Where it stops

Your own conduct. If you personally do something wrong, the entity doesn't shield you. If you're driving the truck, you're exposed. If you gave the negligent advice, you're exposed.

Anything you personally guarantee. Most small business loans and many commercial leases require one. A personal guarantee is a promise to pay personally, and the entity is irrelevant to it.

Certain taxes. Payroll taxes in particular can reach responsible individuals directly.

Obligations you take on personally by signing in your own name rather than the company's.

Where it fails entirely

When the entity isn't respected as separate. Paying personal expenses from the business account, no separate records, no operating agreement, ignoring formalities. A creditor arguing the entity is your alter ego has more to work with the sloppier the operation.

Single-member LLCs are more vulnerable here, because there's no second owner creating natural separation.

What people misunderstand most

That the entity protects the business from you. It generally doesn't. Your personal creditors can typically reach your ownership interest in the company, and depending on the state and the structure, that can affect the business.

What actually helps

Adequate insurance, which handles most of what people hope entities will handle. Separate accounts and clean records. Signing everything in the company's name and in your capacity.

Reading personal guarantees before signing them.

What to do

Check your insurance limits. Check whether your business account has ever paid a personal expense. And look at what you've personally guaranteed — most owners have signed more of those than they remember.
