From reading this, it sounds like Grayson most likely owes the IRS a few million, rather than Derivium owing him. The interest and penalties are accruing every minute. Questions are was he audited, did he pay taxes, and was he knowingly trying to evade income taxes? I hear there’s no statute of limitations on FRAUD.
So it turns out Grayson did receive IDT Stock Warrants with a cost basis of $1.00 per share on February 2, 1996. Still no mention, other than his own words, that he founded the company. IDT Stock peaked at around $70.00 per share in 2004 (currently worth $3.84 per share). With a cost basis of $1.00, if he sold all shares at the 2001 low of $25, (most likely) his taxable gain would have been $13.8 million with taxes due of $2.1 million at 15% Capital Gains Tax Rates.
