Donald Trump’s vice presidential running mate, Indiana Gov. Mike Pence, on Friday released 10 years worth of tax returns to the press — revealing a modest family income, relative to the top of the ticket, and reliable contributions to charity.

The document release draws an uncomfortable contrast for the campaign: Trump himself has not released his tax returns, which he says he has been advised not to release because he is currently under audit. Critics have accused Trump of seeking to conceal his net worth or business practices.

The Pence family’s returns were straightforward. Between 2006 and 2015 the family made an average of about $160,000 a year, largely from Pence’s government income as governor and member of the U.S. House of Representatives.

Their highest combined income was $187,495, in 2009, and their lowest family income was $113,026 in 2015. The couple paid an effective tax rate of 12.40 percent in state and federal taxes in 2015, with similar levels in previous years.

On average, the Pence family gave 10 percent of their take-home income to charity.

“The Pence family has been honored to serve their state and their nation for the past 16 years, while raising three great children and putting them through college,” Pence spokesperson Marc Lotter said in a statement. “These tax returns clearly show that Mike and Karen Pence have paid their taxes, supported worthy causes, and, unlike the Clintons, the Pences have not profited from their years in public service.”
