I'm considering starting an online retail business in PA but I don't want to use my home address to register this so what options do I have?
As a Franchise Attorney I can only say this. You may be able to rent a PO Box at the post office or a private company, like Mail Boxes, Etc. (now known as the UPS Store). Whether a PO Box is acceptable for business license, etc. purposes is another issue. Consult with a good business or franchise attorney in your area for specific advice.
