Cash deposits exceeding $10,000 are automatically reported to authorities (e.g., FINTRAC in Canada, IRS/FinCEN in the US) via a Currency Transaction Report (CTR). However, any deposit—even smaller ones—can be deemed suspicious if it appears to be "structured" to evade detection, or if it is unusual compared to your normal banking activity, often triggering a Suspicious Activity Report (SAR).

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.

To avoid issues, have clear records for the cash's source, like invoices or sales receipts, especially if you deal in cash often.
