The Clintons' annual income increased steadily each year since 2008. That year, their combined total income was $5.6 million; by 2014, it had reached $28.3 million. The couple's most lucrative years were 2013 and 2014, when Hillary Clinton had left her post at the State Department and had joined the paid speaking circuit.
"We've come a long way from my days going door-to-door for the Children's Defense Fund and earning $16,450 as a young law professor in Arkansas — and we owe it to the opportunities America provides," Clinton said in a statement accompanying the release. "I want more Americans to have the chance to work hard and get ahead, just like we did."
Friday's release adds to information from the Clintons' personal financial disclosure back in May. According to that document, Bill and Hillary Clinton made more than $25 million delivering just over 100 speeches since the beginning of 2014.
The new disclosures include itemized speech income for both Bill and Hillary Clinton in 2013. That year, Bill Clinton gave 41 paid speeches and earned a total of $13.2 million from those speeches. His highest-grossing appearances included a speech to Handelsbanken Capital Markets in Stockholm, for $750,000, and one to Leaders and Company, Ltd. in Abeokuta, Nigeria, for $725,000.
Hillary Clinton also gave 41 speeches in 2013, earning $9.7 million in total speaking fees. Her standard rate appeared to be $225,000 for most speeches; her most expensive ones were an appearance for the Jewish United Fund/Jewish Federation of Metropolitan Chicago, for which she made $400,000, and one to Beaumont Health System in Troy, Mich., for $305,000.
The newly released tax returns also revealed how much money Bill Clinton collected for his role as an honorary chancellor of Laureate Education Inc., a massive for-profit college system. From 2010 through 2014, the former president took in $16.5 million from the organization. He left Laureate, which has been a major donor to the Clinton Foundation, in April of this year, less than two weeks after his wife launched her presidential campaign.
During her four-year tenure at State, Clinton made a total of $652,555 in salary. The newly released returns also include her total salary for her final two years in the Senate, in 2007 and 2008 (and into early 2009): during those years, her total Senate earnings were $313,775.
The returns illustrate how Hillary Clinton's last run for the presidency impacted the couple's finances.
In 2007, the Clintons had an adjusted gross income of $20.9 million and paid more than $5.2 million in total taxes. Hillary Clinton also managed to make $123,372 in net profit from her work as an author, while the former president earned more than $9 million in speaking fees and $4.3 million from his own work as an author. They also earned made $2.7 million in income from partnership or S corporation income.
