IR-2017-183, Oct. 31, 2017 WASHINGTON —The Internal Revenue Service today reminded people, including those in disaster areas, who want to file a 2016 tax return electronically to do so by Saturday, Nov. 18, 2017. Filing of paper tax returns will remain available after that date. IRS Modernized e-file, the system that processes electronically-filed individual returns, will shut down after Nov. 18 so the agency can perform annual maintenance and to enable the IRS to reprogram the system for the upcoming 2018 tax-filing season. As a result, any taxpayer needing to file after Nov. 18 will need to do so on paper. While most individuals have already filed their 2016 federal tax returns, certain taxpayers may qualify for an extension until Jan. 31, 2018. This includes taxpayers who live in a federally declared disaster area, have a U.S. tax filing obligation, and had previously obtained a valid 6-month extension of time to file their federal tax return. The federally declared disaster areas include hurricane and tropical storm victims in Georgia, Florida, Puerto Rico, the Virgin Islands and parts of Texas, Louisiana and South Carolina, as well as wildfire victims in parts of California. See the IRS disaster relief page and e-file page for more information.
