People have until Tuesday, April 18, 2017 to file their 2016 returns and pay any taxes due. The deadline is later this year due to several factors. The usual April 15 deadline falls on Saturday this year, which would normally give taxpayers until at least the following Monday. However, Emancipation Day, a D.C. holiday, is observed on Monday, April 17, giving taxpayers nationwide an additional day to file. By law, D.C. holidays impact tax deadlines for everyone in the same way federal holidays do. Taxpayers requesting an extension will have until Monday, Oct. 16, 2017 to file.
