Which business structures each therapy license may use, where to file and what it costs, the taxes to expect, and the order to do it in. Every fee shows the date we checked it.
For all four licenses, we confirmed: LLC and PLLC and Professional corporation. A sole proprietorship works in every state and needs no company filing.

Boards ask for different things, so follow the one for your license.
Check that no one in the state already has the name, and follow the state's name rules for professional practices.
The state requires a registered agent with a street address in the state. That can be you, if you have a street address in the state, or a registered agent company.
