<prompt> Human: My father has always hoarded cash that he has earned and paid taxes on!, and he just gave me and my two siblings 75,000 each in actual cash - a mix of 20s, 50s, and 100s.I do not wish to keep cash-on-hand beyond the 2K that I already I keep in my home safe for emergencies more than 10 years, and Ive literally never needed any of it!.So, Im going to deposit this newly-received cash into my bank account, which Ill use to pay off my mortgage 45K, and add to my taxable investment account.I am very clear that there is nothing illegal here, but it does seem like a cash deposit of this amount will be viewed as suspicious. Is there anything I should do, proactively, to reduce the appearance of impropriety?  <response>: Just deposit it all at once, and if asked where it came from, tell the honest truth. Deposits 10K and up have to be reported by the bank but its no big deal if you truly arent engaged in money laundering.DONT try to fly under the radar by making numerous small deposits to avoid the bank reporting. This is called structuring and is itself illegal.
