Federal income taxes paid in 2017 (jointly with spouse):

Joe Biden - $3,742,974
Kamala Harris - $516,469
Bernie Sanders - $343,882
Elizabeth Warren - $268,484

Donald Trump - $750 https://twitter.com/shearm/status/1310326157062086657

Of course, we did not need a NYTimes investigation (plus I presume some whistleblower) to find tax returns for Biden, Harris, Sanders, and Warren.

For people wondering, Biden's income history looks like this. The big payday was from his post-VP book sales and speaking engagements: https://www.forbes.com/sites/michelatindera/2019/07/10/bidens-made-nearly-twice-as-much-in-2017-than-previous-19-years-combined/#3898c1b868ef

We have sparse details about what Trump makes the federal government pay him. We do know that, in 2017, the Secret Service paid at least $159,000 to his DC hotel and $17,000/month to his Bedminster club: https://www.washingtonpost.com/politics/secret-service-has-paid-rates-as-high-as-650-a-night-for-rooms-at-trumps-properties/2020/02/06/7f27a7c6-3ec5-11ea-8872-5df698785a4e_story.html

That same year, he paid only $750 in income taxes.

Federal income taxes paid for 2019 (jointly with spouse):

Joe Biden $299,346
Kamala Harris $1,185,628

Both could've saved a lot if, like Trump, they committed tax fraud by claiming a debt of "over $50,000,000" to their own LLC: https://www.motherjones.com/politics/2019/09/donald-trump-has-never-explained-a-mysterious-50-million-chicago-unit-acquisition-loan-is-it-evidence-of-tax-fraud/ https://twitter.com/kylegriffin1/status/1310994011398844417
