What to do if you have a customer who pays his employees with checks, but they always turn out to be in hundred dollar balances (not down to the dollar, and certainly never any change). To get checks that even it doesn't seem as though they would be taking out any taxes. Most are not that big, and are just processed through a check cashing company. Any thoughts on what our responsibilities would be SAR wise? We found that they have been doing it for a little while, so the overall total has added up some.
