New analysis of President Biden's tax proposals has suggested that nearly 60 percent of Americans may still face bigger bills, despite his continued promise that no one earning less than $400,000 a year would be impacted. The findings from the nonpartisan Tax Policy Center show that the majority of the burden would be placed on America's richest families - also known as the one-percenters - earning more than $800,000. Around 99.8 percent earning between $500,00 and $1million will pay more an average of $8,810 more in taxes each year.
