If an individual accountholder were to deposit two hundred plus thousand into their private checking account in one go, I guarantee you that his account would be flagged and the Feds would be notified ASAP.
A better idea would be to convert the cash to collectible gold coins, sew them into your clothes, drive to Mexico or hire a boat to Brazil, and then slowly sell the coins off to collectors or dealers on an as-needed, cash-only, face-to-face basis. Even so, you're probably going to attract attention. It's hard to make two hundred thousand dollars dissappear.
Another option: Hire two hundred illegal immigrants to each send a $1000 giro (money order) to their relatives in Mexico. Go to Mexico and have the relatives cash the money orders in. Pay the families 5% ($200 each) for their trouble. Total cost $40,000, but you'd be damned near untraceable.
Another option: Hide the cash in your attic and spend it a little at a time. As long as your lifestyle stays the same and you make no deposits no one will notice anything funny. Downside: if you suddenly buy that sixty-foot cabin crusier, the gig is up.
Another option: Buy a gun, go to the Mexican border and cross illegally. Once in Mexico, dump the gun, then use the cash to purchase Mexican identity papers plus as many politicians, cops and judges as you need to keep inquistive types from snooping around. Mexico is full of generous foreigners with a penchant for privacy. Extra credit: establish a legitimate business in Mexico and use it to whitewash your cash. Put Mexico's traditional corruption to work for you!
There just aren't very many legal ways to obtain $200,000 in cash in the United States. We use checks and transfers to handle legit money in such amounts. If you dump over five grand in cash into a bank account in the U.S. you might as well stamp DRUG MONEY on every bill before you hand it to the teller. Carry big cash in the U.S. and you ARE going to be checked up on. That's a guarantee.
Seriously though it is not difficult to move that kind of cash around. I know someone that sold some laser equipment to some guys in Greece and shipped it over there, then went over to Greece and they gave him $60K USD in cash. He put it in a briefcase and flew back to the USA.
Or buy collectables like LLadro figurines and coins, parcelled out over a long time period. Let your paycheck go where it goes and invest and live on cash. Convert $100 bills at the Vegas crap tables. One at a time, without winning too big.
