Hillary and Bill Clinton released their 2015 tax returns on Friday, showing they paid $3.6 million in taxes on adjusted gross income of $10.6 million.

The release appeared to be aimed at drawing renewed attention to Donald Trump's refusal to release his own tax records.

The Clintons deducted $2.24 million last year, and paid an effective federal tax rate of 34.2 percent and an effective combined tax rate of 43.2 percent. They gave 9.8 percent of their adjusted gross income to charity, according to a campaign release.

Of the the $1,042,000 the Clintons gave to charity as listed on their return, $1 million of that went to the Clinton Family Foundation. The other $42,000 went to Desert Classic Charities.

Hillary Clinton also listed $1.475 million in gross income from speaking, and Bill reported $5.25 million in gross income from speaking. No details were provided on those speaking engagements.



The Clintons made $10.7 million in total income, but reported an adjusted gross income of $10.6 million due to a self-employment tax deduction.

Other significant sources of income included $3 million in book proceeds for Hillary, and $1.6 million for Bill's consulting with GEMS Education, an international education company, and Laureate Education, Inc., a for-profit education chain.

In 2014, the Clintons reported $28.3 million in total income, deducted $5.1 million, and paid $9.9 million in total taxes, according to a tax return posted on the campaign's website. They paid an effective combined tax rate of 45.8 percent in 2014, according to the site.



The Clintons have paid more than $43 million in federal taxes and more than $14 million in charitable contributions since 2007, according to the campaign's website.

Clinton's running mate, Virginia Sen. Tim Kaine and wife Anne Holton, also released 10 years of their own tax returns. They paid an effective combined tax rate of 25.6 percent in 2015, according to the release.



Clinton's previous returns from 2007 through 2014 were already posted on her website. The campaign noted that the couple have now released all their tax returns dating to 1977.
