You don't have to establish it as an official business entity but it is probably a good idea because it will shield you from personal liability.
Not a tax attorney but if you run the business so that you sweep out any income as salary by year end the business itself should not have any taxes. Also, partnerships, like LLCs and Subchapter S Corps, are "pass-through" entities that don't pay taxes, their owners do.
We can help you get a federal tax ID number, it's easy.
Don't know the "accreditation" rules off-hand. What is the nature of the course you plan to teach? For example, a traffic school would obviously need state accreditation.
You do not need to be a NYC resident.
I would not use a PO Box. I would use your actual address or your counsel's address.
Hope these answers were helpful to you and we can do the work for you for a flat fee if you would like some help.
