"The 379 profitable members of the Fortune 500 paid an effective federal tax rate of 11.3% last year" https://www.axios.com/fortune-500-companies-corporate-income...
Amazon, in particular, made over $10b in 2018, but the US government paid them over $100m.
ETA: And for comparison, I made $36k last year (missed a lot of time for health reasons) with a family of 3 (= negative profit, I'm still in debt from it!), and my tax rate is ~8%.
