withdrawing and depositing thousands of dollars on a weekly basis

I don't really like leaving cash around the house or in my wallet. As soon as I am done gambling I like to deposit everything in the ATM (a few grand). And then for the next trip, I go to the bank to withdraw a few grand. I do this like every 1-2 weeks.

Is my bank going to ban me for this type of behavior? What's the threshold limit for frequent withdrawals/deposits before getting cut off?

The only time I ever had a problem with withdrawing money from an account too many times was when I had something like seven electronic transfers from my savings account. There's some federal regulation that restricts how many times you can transfer funds to/from a savings (as opposed to checking, and "electronic" as opposed to ATM or through a teller) account; I got caught out once because I think the period is 35 days, so occasionally two sets of monthly payments went through in the same "month", putting me over the limit; my bank charges $10 per monthly infraction, and can close my account if I repeat too many times in a 6-month period.

As long as the total isn't $10,000 or more within a certain period (so they don't think you're trying to get around the RICO money laundering laws), it shouldn't be a problem.

I know a few professional AP's that have had difficulties in this area in the last year or two. Two National type banks, Chase and BofA, seemed to have been involved.

They way I handle things is to deal with several banks, spread it around, I guess sort of like my blackjack play. :) I have a national type bank which comes in handy for helping you transport money. Just withdraw some funds at the destination location, rather than carry lots of money on planes (or worse yet these days in cars).

But I also have a couple regional or local type banks that I deal with. With these, which is actually where the majority of my transactions take place, I like to introduce myself to the branch manager and explain to him what I do for a living and that I might be making frequent cash deposits and withdraws. This has done the trick for me.

In addition, you may save yourself some headaches, by eliminating some SAR's that might have been generated if the bank was not aware of your situation. Just what constitutes the 'suspicious' part of an SAR is pretty vague and open to interpretation, so informing the branch manager of your situation can only help. Remember with SAR's you are likely not to know they have been filed, so it is better to minimize the chance that they are filed and a discussion with your banker (branch manager) can only help.

I've taken out $1200 a day (my ATM max withdrawal) a couple times a week and never had any problems. Also I've deposited and wired <$10k a couple times as well. I've read an article that said if you make tons of big deposits and big withdrawals you might be flagged as a drug dealer, but knock on wood I've had no problems. I do worry about structuring but I will tell the truth if anything every comes down to it, that I am a professional gambler and need access to cash.

Banks in Vegas aren't too surprised by people taking out thousands, I guess they already know the deal with what the money will be used for. One time at the ATM drive-through with the tube things I've requested $8k and they sent it all through.

The other states, the smaller bank branches usually get a manager involved. They don't carry over $10k and I usually call ahead a few days earlier since they need time to funnel all the money through. I'm worried more about taking money out then depositing, since they probably see a lot of business owners come through with many denominations of bills from their store. As long as the tellers thing I'm a degenerate gambler I could care less, but I still do worry about being flagged for illegal activity, because I never broke the law before in my life aside from a few speeding tickets.

Low four figures less than once a week should not be a problem. More than once per week and / or five figures, might have limits placed on your account

Bigger issue for me, is that you start to have a paper trail of income the IRS can look into

Get to know your bank manager. I also ask for checks for bigger wins so when I deposit a few checks that add up above 10K, I don't generate a CTR (currency transaction report). Instead, I get " Oh you're so lucky, can I go to AC with you?" from my friendly neighborhood teller. Checks also keep me from feeding the hungry machine with my winnings.

Money Market accounts can only be withdrawn from 6 times/month. Anything more than that, and the bank must convert the account to an ordinary checking account, and there are rules about how/when they can open a new savings/MM account for you.

As far as the OP's scenario, I've been doing that for years with my checking account. Inside casinos is (are?) the only place(s?) I ever carry any cash. When I was in PA, I did this with a couple thousand dollars 6-8 times/month with no issue.
