but being overpaid isn't just about the amount earned but the skill and effort involved in doing the job. I'd have to wonder how much of the tip money skycaps earn is reported or if IRS audit triggers are in place to prevent under reporting. Of course you get to state you occupation in your own words. It would take a job code system to set such triggers, I'd think. Hmmm...job codes....have to wonder if that's been mulled over by the treasury dept.
Another largely cash business, as I understand it, is towing. I don't know what the average tow truck owner/operator reports but I've seen a few when I've worked a charity gambling operation (yeah, I know it might be sinful ) and was amazed at the wads of cash these guys would carry in their pockets.
