The options he exercised were about 9% of those he will need to exercise by August of 2022, or the option to purchase them will expire. But exercising those shares will result in a $1 billion federal tax bill, under the top federal income tax rate of 37%, with another 3.8% net investment tax on top of that.
He also will face an unknown amount of state income taxes in California, even though he has relocated to Texas, where there is no state income tax. California has a top state income tax rate of 13.3%.
But Wednesday night’s filing suggests that Musk is not looking to sell all 22.9 million shares he will acquire when he exercises the options between this week and next August.
He already owned 170.5 million shares outright before this transaction, worth $182 billion based on Wednesday’s close. And even after exercising the options this week, he has already qualified for unexercised options to buy an additional 71.4 million shares, including the remaining 20.7 million options due to expire in August 2022.
He made a nifty $2.5 billion profit on the share purchases he made, since he only had to pay $6.24 per share to buy each share under the terms of the 2012 option, which is what Tesla shares cost at that time on a split-adjusted basis. And the shares he acquired were worth $1,180, based on the average selling price of the shares he sold.
But the $2.5 billion profit is only a small fraction of his net worth. His net worth, as calculated by Bloomberg, is nearly $300 billion, making him the richest person on the planet.
A $2.5 billion profit to someone worth $300 billion is the equivalent of the typical US household earning just over $1,000 on a sale of stock it already owned. The Federal Reserve’s most recent estimate puts median US household net worth at $121,700.
