The Indian origin Democratic presidential candidate Senator Kamala Harris has released 15 years of her tax returns, showing that she and her husband Douglas Emhoff earned almost $1.9 million in 2018, according to media reports.

The returns released on Sunday, marking the Tax Day in the United States,  showed most of the adjusted gross income of $1,884,319 in 2018 reported by Harris came from her husband’s earnings as a lawyer, reports The Washington Post.

Harris reported $157,352 in Senate salary and $320,125 in net profit from the memoir ‘The Truths We Hold: An American Journey’ that she released ahead announcing her political campaign.

The returns covered every year that Harris, a former attorney general of California and district attorney of San Francisco, has served in elective office.

Harris and Emhoff have filed jointly since they were married in 2014. Emhoff has reported more than $1 million in income in every year since, and the couple has paid more than $2 million combined in federal taxes.

Harris's income has been relatively consistent since she began serving as San Francisco's top prosecutor in 2004, then as attorney general from 2011 until 2017, the year she joined the United States Senate.

She joins Senators Elizabeth Warren, Kirsten Gillibrand, and Amy Klobuchar, as well as Washington Governor Jay Inslee, in making tax returns public as part of their Democratic presidential campaigns.

Warren has released 11 years of her returns, while Klobuchar and Gillibrand 12. Harris's household income places her in the upper tier of candidates who have shared their returns thus far, The Washington Post reported.

Warren's 2018 returns revealed roughly $900,000 in combined income for her and her husband. Gillibrand's filing included her $167,000 Senate salary and $50,000 in book proceeds. Klobuchar released her tax returns through 2017 and reported less than $300,000 in combined income for her and her husband that year. Inslee's 2018 return reported an adjusted gross income of $202,912.

Former presidential hopeful Senator Bernie Sanders also has vowed to release his tax returns by Monday.

Senator Cory Booker, former congressman Beto O'Rourke and South Bend, Indiana Mayor Pete Buttigieg are yet to release their financial documents.
