The Internal Revenue Service expects the 2014 tax filing season to be delayed one to two weeks due to the federal government shutdown.
The IRS is exploring options to shorten the expected delay, according to a news release from the government agency. It will announce a final decision in December, according to the release.
The original start date for the 2014 filing season was Jan. 21.
Additional time is needed to program and test tax processing systems, according to the release. Approximately 90 percent of IRS operations were closed during the shutdown, which put the IRS nearly three weeks behind its timetable for programming, training and testing demands on systems to provide refund fraud and identity theft detection and prevention.
The agency received 400,000 pieces of correspondence during the government shutdown, according to the release.
"In the days ahead, we will continue assessing the impact of the shutdown on IRS operations, and we will do everything we can to work through the backlog and pent-up demand," acting IRS Commissioner Danny Werfel said in a prepared statement.
The April 15 tax filing deadline will remain in place.
