Ultra-rich skip estate tax and spark a 50% collapse in IRS revenue

Revenue from the U.S. estate tax has been cut in half in two years, new data from the Internal Revenue Service shows, even as dynastic wealth soars.

Just 1,275 wealthy families paid $9.3 billion in estate tax to the U.S. Treasury in 2020. As recently as 2018, the IRS collected more than $20 billion from nearly 5,500 families.

The dramatic decline — to the point where the tax is paid by 0.04% of dying Americans — is largely the result of the tax overhaul enacted by Republicans in 2017, which doubled the amount the wealthy can pass to heirs without triggering the levy.

Married couples can now transfer $23.4 million over their lifetimes tax-free, but families with vastly greater sums can hire sophisticated advisers to get around the tax. Nike Inc. founder Phil Knight used a variety of techniques to transfer billions of dollars to his family tax-free, according to a Bloomberg investigation last month.

Democrats in recent months had proposed cutting the exemption in half and closing many of the loopholes used by the super-wealthy. But, after pushback from some moderate Democrats, the latest version of President Joe Biden’s Build Back Better bill dropped those provisions.

The estate tax’s haul of less than $10 billion now represents an imperceptible share of revenue for the federal government, which in the last fiscal year collected more than $4 trillion. The modern estate tax was introduced in 1916 to help counter the growth of dynastic wealth.

Even before former President Donald Trump and Republican lawmakers loosened estate tax rules, revenue from the levy had stagnated, despite a surge of wealth among the very richest.

In the last five years, U.S. billionaires have doubled their collective net worth to more than $5 trillion, according to the Bloomberg Billionaires Index. At the top of the wealthiest families are the heirs of Walmart Inc. founder Sam Walton, worth more than $200 billion.

Though the levy is now easy to avoid, the IRS data give some insights into the U.S.’s largest fortunes, including where they’re located. More than a fifth of estate-tax payers lived in California, followed by Florida at 13%, New York at 9% and Texas at 6%.

Because the IRS gives families time to file estate tax returns, the 2020 data mostly reflects deaths that occurred in 2019.
