If you are the sole owner of the business, you will be taxed as a sole proprietor (schedule C) whether you do business as an LLC or as a sole proprietor. This is referred to as the disregarded entity provisions. As a sole proprietor, you can deduct your health insurance premiums on page 1 of form 1040, but you will not be able to deduct them on schedule C. This applies whether you do business as an LLC or as a sole proprietor. If you want to deduct health insurance premiums against business income the only way to do that is to be a C corporation. If you are the only employee, then anything that happens will involve you, so doing business as an LLC will afford you no liability protection. Only if you plan on having other people working for you will operating as an LLC give you a liability benefit. If this is a new business and you will be the only owner and employee, I suggest you start off as a sole proprietor and if the business is successful change the structure at a later date. Even if you operate as a sole proprietor, you will still need a separate checking account in the name of the business. You do not have to operate the business under your name, but be sure to file an assumed name certificate if you decide to use a business name other than your own. I do not practice in California, so understand I can not assist you in the nuances of California law.
