I don't know what "business license" you're talking about.
In MA, one journeyman can run a business but can only have one apprentice. He/she needs no other license except their journeyman's license. He cannot hire additional journeymen.
In Ma someone with a master's license can hire as many journeymen as he wants and higher apprentices up to the level allowed depending on how many journeymen he has.
If a master incorporates, he must turn in his individual master's license and he will be issued a new masters license in the company's name.
Ma is currently under the 2020 nEC which they adopted, subject to the MA amendments attached. What I attached may or may not be the most recent issue
