For the personal trainers who do in house training, do you have a business license?

In order to know if you need a business license or not, you need to talk to your tax person I believe. Obtaining a business license is for tax reasons and in some states, if you do business under your legal name, you won’t need a business license. Like I said, the best way to find out if you need one or not is to see the person who helps you with your taxes. Good luck!
