I don't know all the tax loopholes billionaires use, I'm not an accountant. He's probably not giving $500M in cash or all cash, it could be old equipment valued higher, buildings, etc. If I donated an old beat up Chevy pickup, I could say it was worth $10,000 when it was really worth $200 in scrap, maybe. Do that with a fleet of 100 trucks and that's a million right there. You just pay an expert to value it higher if you need to, but you probably don't even need to do that. The IRS isn't in the business of valuing things, and it's hard to prove what the value of something is at any given time. He could be donating it to another company he owns, who knows. If there's one thing I know, billionaires don't pay much tax. You know how the art trick works for deductions?
