Do banks report deposits over $10,000 to the IRS? What really happens when you cross the cash reporting threshold

A cash deposit exceeding $10,000 in a single day triggers an automatic report to the federal government. Financial institutions do not make this decision based on suspicion or branch policy. The Bank Secrecy Act mandates it. When an individual or business deposits large sums of physical currency, the bank must file a Currency Transaction Report (CTR), specifically FinCEN Form 104, alongside IRS Form 8300.
