1. Whatever they got out was divided into five boxes on the Capenter's kitchen table. One each for everyone who got out. Grey turns his down and Harry gives it to Marcone as a weregild. Harry gives ?/half/? of his to Murphy. So 1/8 of the total after the wergild. Check my math. I failed arithmetic.
2. I'll give you some links which explain the tax codes for gifts for education and medical bills. I'm stating this poorly so here's a link.
3. I should tell you this is money from a criminal enterprise. Hitting the gift tax limit might be the least of their worries. It isn't reportable income. You can't bank it. Cash transactions over a certain figure are automatically reported to the IRS.
4. And your cost calculations assume selling the diamonds on the open market. Not gonna happen in the US. You'll need a fence, which will mean a significant discount from market.
5. You weren't suffering under the illusion that you could just drop 20 million in a saving account and call it good? Harry's covered by the White Council, it's one of their purposes. Valmont and Binder are criminals and know the ropes, Murphy is a cop and knows what not to do. Do the archangels have a bank?
6. The word is that Marcone is hosting. Ivy is attending. I assume that Harry and Ramirez are tasked by the White Council. And Molly is apparently in the mix somewhere.
I added the numbers for reference purposes.
1. Ok. I thought you meant he got 1/8th a box. I think he got a tenth of the score. Five boxes (1/5 the score). Marcone gets Grey's, still fifths. Harry takes half of a fifth which is 1/10th. I have no objection to my math being checked. The big complicated equations in high school were never my problem. It was all the simple math.
2. Harry can pay for just about any of his child's needs straight up. He can't just dump money in an irrevocable trust. He can front load about 70K in education expenses and pay as he goes no problem. I did forget the medical expense exemption from the gift tax. Yeah, Harry could just pay those without worrying about gift tax consequences, but it would still be better to funnel it through a 501(c)(3).
3. They stole the diamonds from a place the authorities believe is fictional. Income from a criminal enterprise is totally reportable. In fact, it is illegal to not report it. Here's a CNN article about it:
https://money.cnn.com/2013/02/28/news/economy/illegal-income-tax/index.html. It's still a sticky wicket. Harry would be able to afford a good lawyer to help him do it in a way that minimizes criminal liability exposure. The figure is ten thousand (or was last time I looked). Let's say Harry can sell all the diamonds to one buyer in one go. If that buyer writes him a check, then Harry can just deposit it and pay taxes on it. Additionally, if Harry gets cash, he can store it on Demonreach and deposit large sums and say it is income from his detective business and fill out a form 8300. He can also spend large sums (less than 10K) without worrying about the forms or taxes (sort of). Technically, his largest tax law concern is that he has a massive income that he has to report in the year he received it, but he can't pay it because he wasn't paid in cash or a cash equivalent. The IRS probably has procedures for that; I don't know.
4. That's why I said "[t]hat's not taking into account any discounts if he is fencing them." We need to remember that Harry can now get just about anywhere in the world in short order because of his mother's amulet. He also has access to supernatural markets that we can only speculate about. The first thing I'd look into is selling them to the diamond cartel. I've heard they murder people, and selling them to the cartel probably violates anti-trust laws, so I'd be real careful about it.
5. Under the right circumstances he could. It would be difficult and knowing Harry, he would probably just keep the cash in Demonreach without any sophisticated laundering of it.
6. I got nothing on this one.
