Forming a professional corporation, (P.C.) or professional LLC (PLLC) in New York State is more difficult than most of other sates. Because in NYS, it is a dual process. 

First, you have to get consent from Education Department (excepted for a law firm, just attached a good standing file directly with Department of State), then you go to the Department of State to file the Certificate of Incorporation. 

Second, only members of the same profession can be shareholders of a professional corporation in many (but not all) provinces. The officers and directors of a professional corporation must generally be shareholders of the corporation as well.

Many states are not required Education Department’s consent for filing a P.C. And many states allowed a non-professional be a shareholder or officer in a P.C. But not for NYS.

Even thou you need to have a consent from Education Department first, but you have to check the name available from the Department of State, before getting a consent from Education Department. 

Many people calling Education Department for opining to file the application. But don’t take the person on the phone’s answer as an official answer. It happened to me when I follow their answers to file the application then got rejected. 

From my experience, choosing a name for the P.C. is most important. Most the rejections are due to the improper names. 

The corporate name must end with the words “Professional Corporation” or“P.C.”. The limited liability company name must end with the words“Professional Limited Liability Company” or “Limited Liability Company” or“P.L.L.C.”, “PLLC”.

For the profession of medicine, licensed physicians may use the initials “M.D.”after their name in an entity title only if they have earned that specificacademic degree.

The following is the filing tips I copied some from NYS Education Department’s website, I found it is very helpful:
