How much deposit in bank not reported to IRS?

In the United States, banks are required to report cash deposits exceeding $10,000 to the IRS as part of anti-money laundering regulations. However, deposits under this amount are not automatically reported. It's important to note that even smaller, frequent deposits can raise suspicion and potentially lead to scrutiny if they appear to be structured to avoid reporting requirements. Always consult a tax professional for specific guidance regarding banking and tax obligations.
