Zucman: It's Time To Tax The Billionaires

New York Times Op-Ed:  It's Time to Tax the Billionaires, by Gabriel Zucman (Paris School of Economics & UC-Berkeley; Google Scholar):

Until recently, it was hard to know just how good the superrich are at avoiding taxes. Public statistics are oddly quiet about their contributions to government coffers, a topic of legitimate interest in democratic societies.

Over the past few years, I and other scholars have published studies and books attempting to fix that problem. While we still have data for only a handful of countries, we’ve found that the ultrawealthy consistently avoid paying their fair share in taxes. In the Netherlands, for instance, the average taxpayer in 2016 gave 45 percent of earnings to the government, while billionaires paid just 17 percent.

Why do the world’s most fortunate people pay among the least in taxes, relative to the amount of money they make?

The simple answer is that while most of us live off our salaries, tycoons like Jeff Bezos live off their wealth. In 2019, when Mr. Bezos was still Amazon’s chief executive, he took home an annual salary of just $81,840. But he owns roughly 10 percent of the company, which made a profit of $30 billion in 2023.

If Amazon gave its profits back to shareholders as dividends, which are subject to income tax, Mr. Bezos would face a hefty tax bill. But Amazon does not pay dividends to its shareholders. Neither does Berkshire Hathaway or Tesla. Instead, the companies keep their profits and reinvest them, making their shareholders even wealthier.

Unless Mr. Bezos, Warren Buffett or Elon Musk sell their stock, their taxable income is relatively minuscule. But they can still make eye-popping purchases by borrowing against their assets. ...

So what should be done? ...

There is a way to make tax dodging less attractive: a global minimum tax. In 2021, more than 130 countries agreed to apply a minimum tax rate of 15 percent on the profits of large multinational companies. So no matter where a company parks its profits, it still has to pay at least a baseline amount of tax under the agreement.

In February, I was invited to a meeting of Group of 20 finance ministers to present a proposal for another coordinated minimum tax — this one not on corporations, but on billionaires. The idea is simple. Let’s agree that billionaires should pay income taxes equivalent to a small portion — say, 2 percent — of their wealth each year. ...

[T]his proposal wouldn’t increase taxes for doctors, lawyers, small-business owners or the rest of the world’s upper middle class. I’m talking about asking a very small number of stratospherically wealthy individuals — about 3,000 people — to give a relatively tiny bit of their profits back to the governments that fund their employees’ educations and health care and allow their businesses to operate and thrive.

The idea that billionaires should pay a minimum amount of income tax is not a radical idea. What is radical is continuing to allow the wealthiest people in the world to pay a smaller percentage in income tax than nearly everybody else. In liberal democracies, a wave of political sentiment is building, focused on rooting out the inequality that corrodes societies. A coordinated minimum tax on the superrich will not fix capitalism. But it is a necessary first step.
