Tax day is a costly annual annoyance for most, but for some of the wealthiest people in the United States, this year’s April 18 tax deadline might not mean much. That’s because according to a new report, the richest sliver of our population has managed to avoid billions in tax obligations by hiding their money offshore.

What’s more, it could get easier for the megarich to hide their taxable income, thanks to efforts by the Supreme Court and the Biden administration.

A recent study from academic and Internal Revenue Service (IRS) researchers found that wealthy Americans have stashed nearly $2 trillion in foreign tax havens, with much of that fortune linked to a handful of the country’s richest households.
