Washington: Democrat candidate Bernie Sanders released his 2014 tax returns which showed that he and his wife had a total household income of $205,617. Sanders released the tax return on Friday, a day after being challenged to do so by Democrat front-runner Hillary Clinton at Thursday's debate in Brooklyn, which came after Clinton was questioned about releasing transcripts of her paid speeches, NBC News reported. The tax returns showed the Sanders household paid $9,666 in state income tax and $31,825 in federal income tax, and received a federal refund of $4,172. The documents also showed charitable contributions of $8,350. The household income includes a little more than $46,000 in Social Security benefits and business income of $4,900. At the debate, Sanders said he would release the 2014 returns on Friday, which is traditionally tax day (Taxes are due on Monday this year). Sanders had already released on year of tax returns. He faced questions over releasing more years as he questioned Hillary Clinton's paid speeches and called for her to release transcripts. Last week, Sanders told NBC's "Meet the Press" moderator Chuck Todd that more years would be released, and added, "Trust me, there is nothing that is going to surprise anybody." According to research group, Centre for Responsive Politics, Sanders had a net worth of $460,000 in 2012, making him the 84th wealthiest person in the US Senate.
