I would NOT go sole proprietor… Too much liability. I would go LLC or INC. And that depends on how much money you will be making. Based on your tax bracket, there is a breaking point where an INC is better for taxes. Starting out I would form an LLC, because you will have less taxes to worry about that way. As you grow, an INC is better, because of the way you can structure it, (pay yourself a small payroll for income tax and less SS tax, and then you can pay yourself dividends on the rest…) If your are making closer to 6 figures, an LLC will have higher taxes, because you cant use the lowball salary, and dividend tricks… You need to talk with a tax advisor first. I don’t know what part of Florida you are in, but my brother is a CPA in Kissimmee, and I could get you his info.
Liability wise, they have the same advantages as long as you are not mixing your business and personal spending. Make sure you are using two different bank accounts. If you intermingle, the courts will be able to say that the business account is also a personal account!
