FY2027 NDAA Status: Not Passed Yet

Q: What is the status of the FY2027 NDAA?

As of October 1, 2026, the House passed H.R. 8800 ($1.15T topline) on July 22, 2026, 216–212. Senate cloture on the motion to proceed to S. 4784 failed July 14, 2026, 50–46; a motion to reconsider was entered, and there has been no further Senate floor action. The Senate adjourned September 30, 2026, returns the week of November 9, and leaders deferred the NDAA to the lame-duck session. Fiscal year 2027 began October 1, 2026 without an enacted NDAA.

Q: When will the FY2027 NDAA be signed into law?

Not yet scheduled. Leaders punted the NDAA to the post-election lame-duck session. The expected path is a compromise text negotiated by the four Armed Services committee leaders, which wouldn't require the Senate to pass S. 4784 on the floor. Government funding expires December 11.
