I have seen some helpful answers on here, and maybe someone here can
help.  I reside in New Jersey, and plan on doing business in jersey,
pennsylvania and georgia.  I am planning on registering the LLC in
Delaware for the tax and legal benefits. I am the sole owner.

I have a in-home tutoring business with no home office.  I hire local
tutors as independent contractors to provide the tutoring services.  I
will have an online ING bank account and the business address (my home
address) will be in jersey. My questions are:

1.  Will I be considered doing business in those states even though I
am using independent contractors?
2. Along with question 1, will I have to register in those states as a foreign LLC?
3.  Will I be responsible for any state income taxes, franchise taxes,
or any other fees besides the SE tax and pass-through income tax?
4. Do I have to charge sales tax for my orders with my LLC registered
in Delaware and the company doing business in other states when I am
not registered there?

The goal of this question is to understand my registration liabilities
and tax liabilites in the states where the tutoring will be done using
independent contractors...
