I would open up a couple of new bank accounts at different banks. And dump $3,000 a month into each one This wouldn't attract attention. Start paying the bills I could with cash.
I have always wondered if one just declare it as income, pay the tax man his cut if you could just move on without the worry of the feds going forward? I know there is laws on books mainly at state level of "unjust enrichment" but that is basically saying the money you found was theirs to begin with and/or obtained it through fraudulent means.
The feds would want to know where the money came from. The other idea would be to start some type of business like a repair shop where everyone paid you in cash. But you wouldn't have any real customers. You would have receipts with labor charges on them. Pay your taxes on that.
Everything I have found from the perspective of the IRS is that they really do not care about provable sources of income, just that the tax is paid for what is declared. Proving source only comes into play if you are taking deductions against that amount.
You could always ask Raymond Reddington for money laundering advice, or perhaps an attorney, or a handful of other options. Personally, I would start with a tax attorney.
First thing you do is check the bag for a tracking beacon. Has no one seen No Country for Old Men?
