The Internal Revenue Service said today that it successfully started accepting and processing 2016 federal individual income tax returns on schedule.

More than 153 million returns are expected to be filed this year.

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.
