I'm on the same boat as you, from what ive heard you can either go with an LLC or an S Corporation. I believe with an S corporation you can pay yourself with a dividend so that your company would have no profit/loss for that year, so you would only be paying the income tax on your dividend. I just started reading up on this a couple days ago, so im no expert, but from what ive read, it really depends on the state you are forming your business in. But in either case, you really don't want to be paying self-employment tax (without a company). Then you could be paying around 40%.
