The next U.S. government shutdown is likely to occur if Congress does not approve new funding legislation by the deadline of September 30, 2025. As of now, no full-year appropriations bills for Fiscal Year 2026 have been enacted, and the Senate recently rejected a short-term funding bill to keep federal agencies operating beyond that date. This means if Congress and the President do not reach an agreement by midnight on September 30, 2025, the government will shut down, suspending non-essential federal agency operations until new funding is authorized.
