It's not illegal to carry large amounts of cash, but you must declare amounts over $10,000 when traveling internationally to/from the U.S. by filing FinCEN Form 105; failure to declare can lead to seizure. Domestically, banks report cash transactions over $10,000 (CTRs) and law enforcement can seize cash under civil asset forfeiture laws if they suspect it's linked to illegal activities, even if you aren't charged with a crime.

How much cash can I put in the bank without raising a red flag?

You can deposit any amount of cash without being automatically flagged if it's under $10,000 in a single transaction, but banks must report deposits of $10,000 or more to the IRS via a Currency Transaction Report (CTR). While large, legitimate deposits are fine, making multiple deposits to stay under $10,000 (structuring) is illegal and triggers Suspicious Activity Reports (SARs), leading to potential account freezes or law enforcement scrutiny, so transparency with your bank is best for large sums.
