The U.S. government is set to potentially shut down if Congress and President Donald Trump do not reach an agreement on a spending bill by the end of Tuesday, September 30, 2025. The government funding will expire at 12:01 a.m. on Wednesday, October 1, 2025, and if no funding bill or continuing resolution is passed by then, a shutdown will begin at that time.
The key deadline to watch is midnight between Tuesday and Wednesday. If a deal is not finalized by then, federal agencies will face shutdown procedures, including furloughing many employees and halting various government services except essential ones.
In summary, the official determination of a government shutdown will be known right after midnight as the new day on October 1 begins, contingent on whether Congress passes the necessary funding to keep the government operational.
