While LLC owners enjoy limited personal liability for many of their business transactions, it is important to realize that this protection is not absolute. This drawback is not unique to LLCs, however -- the same exceptions apply to corporations. An LLC owner can be held personally liable if he or she:

• personally and directly injures someone
• personally guarantees a bank loan or a business debt on which the LLC defaults
• fails to deposit taxes withheld from employees' wages
• intentionally does something fraudulent, illegal, or clearly wrong-headed that causes harm to the company or to someone else, or
• treats the LLC as an extension of his or her personal affairs, rather than as a separate legal entity.

This last exception is the most important. In some circumstances, a court might say that the LLC doesn't really exist and find that its owners are really doing business as individuals, who are personally liable for their acts. To keep this from happening, make sure you and your co-owners:

• Act fairly and legally. Do not conceal or misrepresent material facts or the state of your finances to vendors, creditors, or other outsiders.
• Fund your LLC adequately. Invest enough cash into the business so that your LLC can meet foreseeable expenses and liabilities.
• Keep LLC and personal business separate. Get a federal employer identification number, open up a business-only checking account, and keep your personal finances out of your LLC accounting books.
• Create an operating agreement. Having a formal written operating agreement lends credibility to your LLC's separate existence.

A good liability insurance policy can shield your personal assets when limited liability protection does not. For instance, if you are a massage therapist and you accidentally injure a client's back, your liability insurance policy should cover you. Insurance can also protect your personal assets in the event that your limited liability status is ignored by a court.

In addition to protecting your personal assets in such situations, insurance can protect your corporate assets from lawsuits and claims. Be aware, however, that commercial insurance usually does not protect personal or corporate assets from unpaid business debts, whether or not they're personally guaranteed.
