When filing for 1120s for a business in Massachusetts, how do we file a state return for the business?
I filed a 1120s return for a business located in Massachusetts. I have locked everywhere in ProConnect tax, and it wasn't an option to file a state return when filing a 1120s return. Client keeps asking me for his state return of the business.
I also filed his personal return for both federal and state which is what I believe all I had to do. If I missed something can someone, please tell me what it was.
