Quoted from jester523:
Every AZ bank from what I'm told. I use midfirst and chase. These are both business accounts though. So maybe business only? I found out because there was a fee on my bank statement at midfirst, so I called to ask what it was and they told me it was because I deposited too much cash in that month. I then went to chase and opened an account there and they told me it's a state thing. The limit is five 5k per month at chase but if you have over 100k they waive the fee.
The banker told me you can "get around it" by depositing cash in the atm.
Edit - I think it's just business accounts (You can see cash deposit fees in the chase link below)
I looked at the Chase link. I see a bank with 3 tier levels of accounts. If you are a small business, for a $1500.00 balance you get free checking and the agreement that you can deposit up to $5000.00 cash per month with no extra fees. Banks have to hire people to count and handle cash whereas direct deposits are a no-labor transaction. So, if you want to run a lot of cash through your checking account and you don't want to deposit a larger amount of cash so the bank can make some interest off of your cash to help offset bank's labor cost of handling your cash deposits the then you are going ot pay a fee.
In that link, it shows that Chase allows you so many transactions per month before any fees are accessed. Unspoken is what the bank would define as a transaction. Also unspoken is how the bank classifies any checks you deposit. Checks, like cash, need human interaction; so does the bank classify any check in your deposits as cash? Or does each check you deposit count as one transaction?
The banker telling you that you can "get around it" by depositing at the ATM sounds strange. I just don't see every business owner lined up at the ATM to deposit of thousands of dollars of cash to avoid a $15.00 monthly fee.
So, I see a bank making its own policies for business checking accounts. I don't see anything anywhere that supports the notion that Arizona has some cash deposit limit in effect. I not saying that AZ does not have a law about cash deposits but I cannot find anything anywhere that talks about it.
