Other Democratic presidential candidates have released tax returns or promised to do so soon, but Kamala Harris surged past the field Sunday by making public her returns for the past 15 years. The release covers every year Harris has held public office, Politico reports, starting when she was elected district attorney of San Francisco. The most recent return for Harris and her husband, Doug Emhoff, a lawyer, showed an adjusted gross income of $1.89 million. That total included her Senate salary and $320,000 in income from her book, "The Truths We Hold." They paid $563,426 in federal taxes for 2018 and donated $27,000 to charity. Harris and Emhoff have filed jointly since they married in 2014. Over the past five years, per CBS, the couple has paid more than $2.2 million in federal taxes at an average effective tax rate of about 33 percent.
During the 2016 campaign, Hillary Clinton released tax returns for the past eight years. Bernie Sanders released a summary of his 2014 return and said he'd give details once he won the nomination. This time, the Democratic field is larger and the issue pressing, given the battle over releasing President Trump's returns. Elizabeth Warren's release last fall covered 10 years, and she's since released her 2018 return. Sanders has said he'll release a decade's worth by Monday. But Sunday's release by Harris, an aide told CNN, makes "her the most transparent candidate in the field when it comes to information about personal finances." (Read more Kamala Harris stories.)
