The Zuckerberg Tax

Hugh Pickens writes "David S. Miller writes that when Facebook goes public later this year, Mark Zuckerberg plans to exercise stock options worth $5 billion of the $28 billion that his ownership stake will be worth and since the $5 billion he will receive will be treated as salary, Zuckerberg will have a tax bill of more than $2 billion making him, quite possibly, the largest taxpayer in history. But how much income tax will Zuckerberg pay on the rest of his stock that he won't immediately sell? Nothing, nada, zilch. He can simply use his stock as collateral to borrow against his tremendous wealth and avoid all tax. That's what Lawrence J. Ellison, the chief executive of Oracle, did, reportedly borrowing more than a billion dollars against his Oracle shares to buy one of the most expensive yachts in the world. Or consider the case of Steven P. Jobs who never sold a single share of Apple after he rejoined the company in 1997, and therefore never paying a penny of tax on the over $2 billion of Apple stock he held at his death. Now Jobs' widow can sell those shares without paying any income tax on the appreciation before his death — only on the increase in value from the time of his death to the time of the sale — because our tax system is based on the concept of "realization." Individuals are not taxed until they actually sell property and realize their gains and the solution to the problem is called mark-to-market taxation. According to Miller, mark-to-market would only affect individuals who were undeniably, extraordinarily rich, only publicly traded stock would be marked to market, and a mark-to-market system of taxation on the top one-tenth of 1 percent would raise hundreds of billions of dollars of new revenue over the next 10 years."

Such systems have been proposed before

and are uniformly shot down as a tax on wealth rather than income. And that is correct: it is, after all, an income tax, not a wealth tax. The author of this piece wishes us to ignore his sleight of hand. That is, this is not a bug, but a feature.

One more issue

[Scareduck]

Calling this "mark to market" is horribly misleading, not only for the reason I cited above (it's actually a wealth tax, not an income tax) but also because a wealth tax would demand a substantial fraction of assets would have to be shed each year, thus diluting the market for that asset class. It becomes an Heisenbergian problem.

A wealth tax assumes liquidity: for instruments such as REITs where the underlying asset is not itself terribly liquid (imagine, for instance, owning a shopping mall outright), how does one go about liquidating such a thing in part? Finding another partner? And then the next year, when the same thing has to happen again?

Finally, the issue remains of incentives. France has a wealth tax, and the net result of this is that while it has collected $2.6 billion (equivalent), it has resulted in $125 billion in capital flight since 1998.
