note: be careful about how you accumulate said cash. CTRs are generated if you withdraw too quickly. This is very bad advice, as it's illegal in the US to intentionally evade CTRs by aggregating smaller transactions. It's known as structuring: http://www.irs.gov/irm/part4/irm_04-026-013.html http://www.irs.gov/irm/part4/irm_04-026-013.html Also, CTRs aren't inherently a bad thing, and they aren't generated behind your back. If you hit the $10k reporting limit, it's a simple one-page form, and you're on your way. Legitimate businesses are required to complete them all the time. Suspicious Activity Reports (SARs) are filed at the discretion of the institution, are secret, and are independent of the transaction amount. Withdraw $9,990 and you'll probably have a SAR under your name instead of a CTR. Ditto if your deposit smells like drugs, or if you're dealing in large amounts of currency as an individual, and the bank staff can't determine why.
