Since the goal of your new business is to generate income and you are working with a partner, then you should choose a business structure (partnership; LLC; etc) first. Then register your business name with your local government office (county office likely). Very quick and inexpensive.
Then you will take your DBA certificate (given to you when you register the biz) and open a business checking account. Also quick and easy.
Now you will be ready to accept payments and pay your taxes.
Since you are not selling products yet you don't need to worry about sales tax. That's another step. When you are ready, you simply fill out a form with your state tax department and you're set.
