Ive been asked a couple times now on phone interviews if I am incorporated, have a fed tax ID #, etc. and Im starting to wonder why... I operate as a sole proprietor, so my tax ID is just my SSN, and I havnt felt the need to form an LLC or the like yet. Is hiring an LLC over an individual more attractive to line producers though? I know it can change the way they make payment... Does it just allow them to bypass a payroll company?
