No. Also, note that depositing cash in any amount is not a crime. It's just that the bank must report it if it's over $10,000 in all cases, and also for smaller amounts if it's 'suspicious'. But neither the large cash deposit report, nor the suspicious activity report, have any direct tax consequences or impose any restrictions on what you do with the money. If as you say it's your money, that you received legitimately, and paid or will pay whatever taxes may (or may not) be due on it based on where it came from, then there shouldn't be a problem, and there's no reason to structure.
