The prior answer offers good advice. Here are a few additional thoughts.
When operating in the corporate arena, it is important to know what "hat" you are wearing at any one time. Are you making a decision as an owner or as a corporate officer carrying out tasks?
Keep in mind that a corporation or LLC can only operate through their agents. So it is good to keep records or minutes that reflect what decisions were made and what authority a corporate officer was granted. If you are going to loan money to your corporation, then best to create a promissory note assessing a reasonable interest rate. Best to keep the corporation's funds separate from that of the owners. If you want the protection of limited liability you have to be willing to respect the integrity of the entity.

First, from a legal stand point, GA doesn't recognize the difference between an S-Corp or C-Corp. S-Corp and C-Corp designations are for IRS tax purposes. In GA, a corporation whether S or C class must keep corporate formalities such as keeping corporate minutes and elections, being adequately capitalized, and maintaining the corporation as a separate entity by doing things such as maintaining a separate account. There is also what is known as a statutory close corporation that isn't required to keep the same corporate formalities as a regular Georgia corporation but that is another discussion.
Commingling assets means that there is no distinguishable difference between the ownership and control of an asset. As an example, if you are doing business through your personal bank account by accepting payments from customers through your personal account, you are commingling your personal funds with your business funds. Such would be an example of commingling and a reason to ask a court to pierce the corporate veil of a business entity.
Whether someone can pierce the corporate veil of a company is a highly factual question that requires legal research. If you believe that your may be personally subject to litigation due to the Plaintiff attempting to pierce the corporate veil, you must hire a corporate litigator NOW.
