banks have to report any transaction that are 10k +, if your single deposit is 10K or more, check money order cash or direct depo, it will get reposrted, others, u can do 9k a week and ur good, as just dont do 9k cash, i m banker and a business owner both, so i have had my fair share of this, i own a gas stastion and made that mistake of depositing the weekends deposit all at once over 10k, they made me fill out a form and it gets reported, now i work at BofA and learned all about it, just stary away from 9k cash depos, and u'll b aite, wires over 10k get reported to....
