C-Corporations, S-corporations, LLCs and sole proprietorships have different tax advantages and burdens. It’s all a matter of whether your business and personal situation is such that you are legally allowed to operate as that entity, the type of business you are operating, how much net income you are making, and the tax benefits you value most in your overall situation. I can help you break down these categories to target the best business entity for your situation, and how to move you from one entity to another if necessary for maximum tax savings.
You can compare tax effects of different entities at my C vs. S Corporation, Corporation vs. Partnership and Corporation vs. LLC pages.
