For that amount of money, you should hire a tax specialist. Depending on FR advice would be foolish, even if well-intentioned.
For that amount of money, no one is really going to look. If you want to not pay your taxes, buy gold or bitcoin. You can unload both anonymously. Anything else and the IRS will seize it for the unpaid tax bill.
ALWAYS PAY YOUR TAXES! You do not want them combing through your business.
