WASHINGTON — Hillary and Bill Clinton earned $10.6 million last year, according to a tax filing released by her campaign that sought to pressure presidential rival Donald Trump to disclose his tax returns.

The filing shows that the Clintons paid a federal tax rate of 34.2 percent in 2015. The bulk of their income – more than $6 million – came from speaking fees for appearances made largely before Hillary Clinton launched her campaign in April 2015. They gave more than $1,042,000 to charity, with $1 million going to the Clinton family foundation. That is the financial vehicle the family uses to give money to museums, schools, churches and other charitable causes. It is not the same organization as the better-known Clinton Foundation.

The Clintons’ income puts them well within the ranks of the top 0.1 percent of Americans, though they pay a higher tax rate than many of their elite peers, according to an analysis by the nonpartisan Tax Foundation, based on 2013 data.

The release on Friday is part of an effort to undercut Trump’s character by questioning the celebrity businessman’s record. Trump has refused to make his filings public, saying they’re under audit by the Internal Revenue Service and he’ll release them only once that review is complete. All major U.S. presidential candidates in modern history have released their returns.

Trump steered clear of mentioning his personal taxes Friday. A spokesman pointed to Clinton’s move to delete tens of thousands of personal emails from her private account as secretary of state and questions about whether she used her government post to benefit the Clinton Foundation.
