The bank i worked at filed an internal report for any cash transaction over 3k and reported any cash transaction over 10k to the feds. But they get an annual audit and I'm confident the 3k transactions got reported in those as well. Even if you do it in different transactions, if they all occur on the same day it is tracked and gets reported as a total amount for that day. They'll ask you for you social (if you don't bank there and are cashing a check drawn on them) but if you bank there they already have it and your DL #, DOB, Occupation, address and what the money is for...the teller cannot bypass it. Either give them the info or they have to cancel the transaction all together. Every transaction gets an OFAC check (patriot act bs). If you have a bank account the teller can see everything about you. Be nice to your teller they could ruin your life easily. I quit my banking career bc I didn't want to be standing in a bank when the s hit the fan. I knew I'd be a sitting duck. It's a "gun free" zone but you bet your ass I had a gun on me every day I was there and so did my branch manager. No way in hell I was going to be in charge of that amount of money with no gun.
