Your client is thinking of opening up a business that will sell alarm systems. The business will be headquartered in New Jersey, but there will be employees in various other states. In some states, the employees will merely be soliciting sales. In other states, the employees will be performing repair and installation services. There will be some travel by the employees between the states. What state tax issues would you advise your client need to be addressing the various states?
