Find a different job very soon. If you're 23, then you don't want to be connected to a disreputable or scandalized employer where you've had enough exposure for the recruiter to have doubts on your integrity. I don't think a little more $$$ or easy work hours is worth that long term hassle.
Every single small business cuts taxes. How the hell do you think they make any money? Don't even get me started on personal owned hair salons, tutoring facilities, etc... I can't believe people are comparing it Enron. LOL.
You realize everything you posted on here could easily be found by anyone and used as evidence against you? im not a lawyer and just trying to give ya a heads up.. You stated you know it is shady/illegal, but keep on doing it because "everyone likes to make a tax free buck"..... I hope you haven't gotten in too deep, but I would suggest not posting anymore evidence online against yourself, just in case ***** hits the fan.
Your loyalty is to your superiors (your boss) and your company. You must do anything to make as much profit for your company. Thus I suggest doing nothing, and being content still having gainful employment.
