This list has been updated.

Agencies on Friday began posting their contingency plans online to prepare for a possible government shutdown on Tuesday, Oct. 1. If the government closes, approximately 800,000 federal civilian employees could be furloughed. Those placed on unpaid leave will receive official furlough notices on Oct. 1, if necessary.

We’re compiling a list of agency shutdown guidance as it’s posted. We’ll continue to update this information over the next few days as agencies publish their plans. The Office of Management and Budget also will link to agencies’ guidance on its website.
