A week after unveiling legislation that would make it easier to send C.E.O.s to prison, Elizabeth Warren rolled out a proposal on Thursday likely to send an exponentially larger chill down the corporate world’s collective spine: a tax on their profits, specifically designed to eliminate loopholes and exemptions. That sound you hear is the inhabitants of the nearest c-suite shitting a brick.

Called the the Real Corporate Profits tax, the 7 percent tax would kick in at the first dollar over $100 million in profits, which, in 2018, would have affected roughly 1,200 companies. In her Medium post debuting the plan, Warren writes that the reason for not simply raising the current corporate tax rate is that current rules are so “littered with loopholes” that firms’ highly paid lawyers would simply find a way around it. Because corporations have an incentive to report as low a profit as possible to the I.R.S., the 7 percent tax would apply to the figure they report to shareholders and the public. An accompanying analysis estimated the tax would raise at least $1 trillion over the next 10 years.

As an example, Warren said Amazon would have paid $698 million in taxes last year under her plan, rather than the zero dollars and zero cents that it actually got away with. And the Seattle juggernaut did not appreciate the name check! “Amazon pays all the taxes we are required to pay in the U.S. and every country where we operate, including paying $2.6 billion in corporate tax and reporting $3.4 billion in tax expense over the last three years” the company said in a statement. “Corporate tax is based on profits, not revenues, and our profits remain modest given retail is a highly competitive, low-margin business and our continued heavy investment.” To which Warren essentially responded, bitch, please:

In a statement, a spokesperson for Amazon told the Hive: “We have invested more than $160 billion in the U.S. since 2011, building a network of more than 125 fulfillment and sortation centers, air hubs and delivery stations as well as cloud-computing infrastructure and wind and solar farms. We invest heavily in research and development at our Seattle headquarters and 18 tech hubs across the country. We are creating tens of thousands of quality jobs each year with industry-leading pay for people of all skill levels, bringing our total workforce in the U.S. to more than 250,000.”

Warren wasn’t the only one Amazon tussled with on Thursday. After founder Jeff Bezos used his annual letter to shareholders to “challenge [Amazon’s] top retail competitors (you know who you are!) to match our employee benefits and our $15 minimum wage,” C.E.O.s from eBay to Walmart snapped back that Amazon should focus on paying its taxes and dinged the company for “competing with [its own] sellers” and “[bundling] endless services to create barriers to competition.”
