LLC is a "Limited Liability Corporation". "Sub-chpater S" is a reference to the IRS code that creates a different sort of limited liability corporation. The intent of LLC and S corporations is to allow a small business to limit their liability while avoiding some of the requirements of a full-fledged corporation.
When I was making this decision I talked to a lawyer and to an accountant. Both recommended the LLC route, but I thought their recommendations were more about future fees to them than actual benefits to my company. I did some research on the web that seemed to confirm my first impressions (I have not done business with either the lawyer or the accountant since) and I'm doing business as a Sole Proprietor.
Check with a lawyer and an accountant that you feel you can trust. Then carefully evaluate their recommendations in the calm of your own mind. If the two don't jibe then either try a different pair of crooks or use Google.
The key to me was the risk/cost ratios. In my case neither an LLC nor an S corp would protect my personal assets in a dispute about an engineering decision (the PE imparts
personal liability in most cases). Once I got to that point I couldn't see paying these folks several hundred dollars up front and several thousand a year thereafter.
Good luck to you, and don't make any decisions based on what you read in this forum--use that information to formulate your own questions to professionals that you employ.
