When you deposit a large check, your bank typically places a temporary "exception hold" (often 2-7 days) to verify funds, potentially calls you for identity confirmation, and may release a small portion immediately while holding the rest to check the check's authenticity and the payer's funds, with longer holds possible for new accounts or suspected fraud. Banks also report large cash/check deposits over $10,000 to the IRS, but this is a routine process, not usually an issue unless suspicious activity is detected.
