How do you file your taxes, under what type of business (Corporation, LLC,ect)? I am trying to decide how to file for my business from now on (I have been a sole proprietor for the past 3 years - I have a small two man operation with me working another job on my own). My approach to this decision would be to try and do what everyone else does. Also, if I decide to buy and sell real estate and possibly own another small business, what should I do (does that have any bearing on the decision?).
