My business is a single member LLC. I think I now understand what to do regarding attaching the Schedule C to the 1040.
Does it make a difference on the amount of taxes owed if I use my EIN or SSN? My question refers to any tax, federal or state. For example, if I do work under my EIN, don't I then owe state sales tax for the money earned? Whereas if I did the work under my SSN, I wouldn't owe that sales tax?
