The documents revealed that Trump paid far less than expected in taxes in the years he was in office. He reported significant losses every year, and the amount he paid in taxes reflected that.
In 2018, however, he did pay almost $1 million in taxes and $133,445 in 2019. While those might seem to be astronomical amounts to us peons, it is, in fact, a very small percentage of Trump's reported income.
Although the IRS is supposed to conduct mandatory audits of the president's tax returns, no audit was done until 2019, when the committee first requested the returns.
