this is all based on personal experience, in Texas, and reading a bit on the subject (nolo.com is great, and they have books as well), so may vary. Not a lawyer, just a guy who started a few businesses.
So, as far as how to organize:
A sole proprietorship is easiest to create and register, and cheap, but it means income is your own as well as any legal exposure. Your business = you.
A corporation is a separate entity in both regards and if I remember right costs about $350 to set up and register. It comes with some additional pains like the need to file “franchise tax” forms each year. Income can be the corporation’s and legal exposure for you is limited somewhat. Your business = it’s own entity.
The advice I received from a lawyer and accountant basically boiled down to if your business is anything more than a hobby, you should go ahead and set up the corporation. (there are different types and it’s probably better to just read through those)
Other things to consider… Are you going to charge sales tax to anyone? If so you need to register with the state as well and get a permit. Your business may also need a permit depending on what you’re doing. If you’re going to do business with any public entities (government) then sometimes they have additional perks for women and minority owned businesses, it’s worth looking into requirements if that’s a possibility.
If your husband is going to participate, then it can make sense to put him as a partial owner, but if not you don’t really need to. As your husband he gets your assets anyway if something happens to you, right? This would be no different.
As far as better for taxes, my understanding is that it depends on so many things it’s better to just sit down with someone. Your current household income, how much business you expect to do, whether or not you intend to turn a profit right away, and whether you will draw a salary are all considerations for both business type and taxes. Pay someone for a few hours of their time to get some custom answers up front. They’ll probably have additional advice that can save you time and confusion down the road.
Good luck with it, let us know when you get it going so we can support your venture.
