You can deposit any amount of cash without the IRS knowing if it's legitimate, but banks must report cash deposits or withdrawals over $10,000 via Currency Transaction Reports (CTRs) and suspicious activity over $5,000 via Suspicious Activity Reports (SARs), triggering IRS awareness for large sums. Attempting to avoid reporting by breaking deposits into smaller amounts (structuring) is illegal and can still be reported by the bank, leading to penalties, even if the source of funds is legal.

Can I deposit $5000 cash in a bank?

Yes, you can deposit $5,000 cash in a bank, as most banks don't limit deposits, but it's close to the $10,000 federal reporting threshold, so you might get asked about the source, though it's a normal process for the bank to check, not necessarily an audit trigger. Large deposits trigger a Currency Transaction Report (CTR) to the government to prevent money laundering, but it's for legitimate reasons too, like wedding gifts or business income, and you should be ready to explain the source if asked. 

Is depositing $2000 in cash suspicious?

Depositing $2,000 in cash isn't inherently suspicious, but it can attract scrutiny if it seems unusual for you or if it's part of a pattern to avoid reporting thresholds (like the $10,000 limit for Currency Transaction Reports), with banks potentially filing a Suspicious Activity Report (SAR) for amounts over $5,000 or for structuring. To avoid issues, have clear records of the cash's legitimate source (e.g., business invoices, pay stubs) and avoid breaking up larger amounts into smaller deposits to hide them (structuring).
