This statistic I think is with respect to those that owe tax rather than for all households (it excludes 1/3rd of those that file returns):
"The most recent IRS data revealed that Americans who filed taxable returns paid an average income tax payment of $15,322 in 2018. This number was calculated based on the returns of over 153 million American households who filed during that period, which included just over 100 million taxable returns."
I'm actually fairly shocked that $10K is the median income tax liability given that a substantial percentage of households pay no net federal income tax.
I can't imagine the majority of people happily accept a 10% (more for half of households) tax hike, when companies already CC the IRS on all the forms they're regurgitating.
