When I helping my step-dad Sunday and we were talking about me setting up my business and I told him in a couple weeks I'm going to register my name and get a tax id#. He said be careful when I get the tax# that my utlities (phone, electric, etc.) at home will be double or triple in price because of it being a business. Now at first I'm going to have to run things out of the home until I can get a place of business. If I register my name and tax id# using a P.O. Box will the price of utilities and such go up? Also, how about a cell phone # for the business instead of a land line? I'm trying to get everything legit before I start and was just wondering how to go about things like this.
