I'm working through the tax calculations for different scenarios. Starting with the total income of 300k and the base tax and interest of 102k, then comparing what happens under voluntary disclosure versus nonwillful underpayment, where the penalties stack differently depending on the approach taken.

If detected outside the program, the fraud penalty and offshore account penalties push the total to 409,500. For quiet amended returns, I'm calculating the expected value as a weighted probability between detection and voluntary disclosure outcomes, which comes to 317,250. The no-action scenario has an expected value of 245,700, which is actually lower than voluntary disclosure on pure financial grounds, so there's no tradeoff there—voluntary disclosure is the better choice economically.

I'm also noting that the criminal referral risk varies by path, and checking the liquidity situation: the voluntary disclosure amount of 228,000 is payable from the 260,000 liquid assets, leaving a 32,000 cushion, though borrowing might be worth considering to preserve reserves. Now I'm looking at the willfulness evidence—the taxpayer checked "no" on their form despite fifteen years of returns, and there's an email exchange that's relevant to establishing intent.

The conduct shows voluntary, intentional violation of a known duty, so I cannot certify this as nonwillful. Rule 5 makes false certification a separate offense with no protection, and I'm ethically prohibited from describing the conduct as nonwillful or assisting any false statement. The twelve-day window under rule 3 means eligibility ends when the authority receives the taxpayer's identity, so I need to act immediately—file and submit the disclosure request today, since this option depreciates as time passes. For payment, I'm structuring it as: pay the tax, interest, and penalties; borrow against the domestic investment account for the remainder; avoid any liquidation or movement of the offshore account that could look like concealment; and preserve all banker emails and records.

The numbers show the offshore penalty alone is substantial at 108,000, and comparing the total exposure of 228,000 against the expected outcome of 317,250 or 245,700 with criminal risk factored in—the voluntary disclosure
