Tesla’s stock was going for more than $1,000 a share when Musk bought 22.9 million shares late last year, but by the time he sold the 9.6 million shares last week, the price had fallen, and he received only $883 a share, on average. That difference comes to about $1.7 billion.
In the eyes of the IRS, the sale could count as a massive tax loss that would reduce Musk’s future taxes by between $400 million and $700 million.
It may sound like cheating, but it’s legal — and a common practice for wealthy investors.

Here’s how Musk could get his tax break.
Musk acquired Tesla stock through the exercise of options at the end of last year, part of his compensation for being CEO. Musk paid only $6.24 per share to exercise the options, even though each share was worth more than $1,000 each.
The basis is typically the cost of shares or other assets at the time they’re purchased. That amount is deductible from the revenue an investor receives when calculating capital gains tax.
It’s not certain that that those shares he acquired last year are the ones he just sold. But it’s probable, tax experts say, because those would have the highest cost basis of any of the shares he owns.
“Of course, you’re going to sell the big basis shares first, and you’re allowed to do so in the law,” said Lee Sheppard, contributing editor of Tax Notes Federal.
Tax law allows investors to pick and chose which shares they sell when they are disposing of only a portion of a holdings. And the tax experts agree that selling the shares Musk acquired through exercising 22.9 million options in the final two months of 2021 would be the most beneficial for his future tax bills.
“It’s a common strategy,” said Steve Rosenthal, senior fellow, at the Tax Policy Center, a nonpartisan think tank. “Taxpayers like to select their losses as an investing tool.”
Musk’s paper tax loss means he can avoid paying taxes on that much capital gains in the future, depending upon how long he held onto the whatever asset he is selling for a profit. He will be able to cash in that tax loss only against future capital gains in order to reduce his taxes, not shield what he might owe in regular income tax. But he can wait and use it whenever he does have a gain.
“He can carry it forward forever and ever,” said Sheppard.
It’s possible he might not have to wait long.
The fact that Musk is able to use the value of the shares at the time he acquired them to calculate capital gains or loss, rather than what the nominal amount the shares cost him, is a big advantage for him and others in his position.
“It’s a very good deal,” said Rosenthal. “If someone gave me the chance to buy Tesla shares for $6.24 a share when they were worth $1,000, I’d jump at it. Even if I had to share big chunk of that with the government, I’d be way ahead.”
