body: Today US Senator Elizabeth Warren released her family's tax returns, as [reported here by LA Times](https://www.latimes.com/politics/la-na-pol-elizabeth-warren-tax-return-20190410-story.html?utm_source=dlvr.it&utm_medium=twitter). Article says that:
  
  
  
  > 
  > Democratic presidential candidate Elizabeth Warren has released her
  >  tax return for 2018, reporting that she and her husband paid more than
  >  $200,000 in taxes on a joint income of about $900,000 last year.

  That comes down to about 22% tax rate. When I take into account marginal tax rate total tax comes up to about $275k = $164k+0.37\*$300k which is effectively 30%, following [this table](https://www.forbes.com/sites/kellyphillipserb/2018/11/15/irs-announces-2019-tax-rates-standard-deduction-amounts-and-more/#3b321e6d2081):

  Is that calculation correct? Does it mean Senator's family got deductions worth $75k in taxes?
