FBI opens investigation into IRS tax data leak

Amazon’s Jeff Bezos, Tesla’s Elon Musk, and investor Warren Buffett were among those who had tax information leaked

The Federal Bureau of Investigation has opened an inquiry into the leak of personal income and tax data of some of the wealthiest Americans, a law enforcement source tells Fox News.

The independent, nonprofit publication ProPublica last week published the tax liabilities and incomes of billionaires including Amazon’s Jeff Bezos, Tesla’s Elon Musk, and investor Warren Buffett, among others. The publication says it obtained thousands of tax returns for the country’s wealthiest individuals that span more than 15 years. 

The records showed Buffett paid a "true tax rate" of 0.1% from 2014 to 2018 while Bezos and Musk paid 0.98% and 3.27%, respectively, according to ProPublica. The top marginal tax rate is 37%, but that rate is only applied to any income above $510,301 for individual filers. ProPublica says the "true tax rate" is calculated by comparing how much the individuals paid in taxes with how Forbes estimates their net worth grew over that time.  


Word of the investigation comes two days after Senate Minority Leader Mitch McConnell and Republican Sens. Chuck Grassley and Mike Crapo demanded the Department of Justice and FBI to look into the leak. It is illegal to publish an unauthorized tax return.
