I want to open a business, but I do not know in which state to open it, because of the profit taxes. Does someone know how can I find out which are the profit taxes for each US state? I understood that in some states are lower."
Your best bet is to open the business in the State that you live in. I think that would keep things much easier for you. Besides, why would you want to do business in a different state that you live in? Its to complicated...
What you need to do is go to your state resources. They usually have a web site and check out and see what the tax bracket for taxation is.
