Amazon will pay ZERO in taxes on over $11 Billion in profits.

Thanks to the new Tax Cuts and Jobs Act (TCJA), Amazon’s federal tax responsibility is 21% (down from 35% in previous years). But with the help of tax breaks, according to corporate filings, Amazon won’t be paying a dime to Uncle Sam despite posting more than $11.2 billion in profits in 2018.
How is that possible?
