Senator Elizabeth Warren criticized Amazon's tax practices following the conclusion of Prime Day 2023, reminding that the company paid no federal income taxes in 2018 despite making over $10 billion in profits. Warren noted that Congress passed her plan for a minimum tax on massive corporate profits, which became applicable from Dec. 31, 2022. Amazon paid zero federal taxes in 2018 and 2019, but had to foot a federal tax bill of $162 million in 2019, a fraction of the $13.98 billion it earned as pre-tax income.
