The top 25 richest Americans saw their wealth rise to $401 billion from 2014 to 2018 collectively and they only paid a total of $13.6 billion in federal income taxes in that period according to an analysis of IRS documents by ProPublica.

Moreover in 2018, the top 25 wealthiest Americans reported $158 million in wages, which is just 1.1% of what they submitted in their tax form as their total income. Most of their income came from the sale of stocks, bonds, dividends and other investments which are taxed at a lower rate.

Warren Buffet's wealth rose by $24.3 billion between 2014 & 2018 but he paid only $23.7 million in taxes, which means the effective tax rate was about 0.1% or in other words, he paid less than 10 cents for every $100 he added to his wealth.

In 2007, Jeff Bezos paid "zero" in federal income taxes while his wealth grew to $3.8 billion. Similarly in 2011, when his wealth stood at $18 billion, he filed a tax return reporting a loss that year and even received a $4,000 tax credit for his children.

On the other hand, the median income of an American household was about $70,000 annually & paid 14% in federal taxes. With the new tax rates, couples earning more than $628,300 will receive a deduction as high as 37%.
