NDAA Amendment Tracker: FY2027 House vs Senate

Amendments by chamber

• House (H.R. 8800): passed the House with a $1.15T topline. The official list of House floor amendments is on the Congress.gov amendments tab for H.R. 8800.
• Senate (S. 4784): approved by the Senate Armed Services Committee with a $1.14T topline. No floor amendment votes, because the bill never got past the motion to proceed. Any filed amendments are listed on the Congress.gov amendments tab for S. 4784.
• Final bill: Expected December leaders' compromise: a text negotiated by the four Armed Services committee leaders, which wouldn't require the Senate to pass S. 4784 on the floor.

House vs Senate differences to settle

Any compromise has to reconcile two different texts. In the parsed bill text on this site, H.R. 8800 has 723 sections and S. 4784 has 611. 411 section numbers appear in both bills, 312 appear only in the House bill, and 200 appear only in the Senate bill. A shared number does not mean the text matches; the House vs Senate diff shows the word-level changes for each section.

• Sec. 847: Promoting the United States drone industrial base is in the Senate bill only.
• Military pay raise: how the House and Senate bills handle the January 2027 raise.
• H.R. 8800 vs S. 4784 guide: the main policy fights between the two bills.

Recent reporting on provisions in play

• Unions back Senate push to limit stock buybacks for defense contractors (Federal News Network, 2026-10-06). Labor unions led by the UAW urged the Armed Services leaders to keep Section 815 of S. 4784, which would bar Pentagon contracts with companies doing stock buybacks, in the final NDAA. The House bill has no such provision, and the U.S. Chamber of Commerce urged Congress to drop it.
• Congress Heads Home, But MOAA's NDAA Push Continues (MOAA, 2026-10-05). House and Senate are reconciling H.R. 8800 and S. 4784 through an informal process rather than a traditional conference committee. MOAA and other military and veterans groups met SASC staff Sept. 23 to press for health care, reserve benefits, housing safety, and child care provisions in the final text.

What happens next

The Senate is scheduled to be in session only 8 days in November and 14 days in December, counting Fridays, which aren't typically Senate workdays. Government funding expires December 11, competing for lame-duck floor time. Thanksgiving recess is November 23–27 and the Senate is out December 21–31. Sen. Mike Rounds said, "I think the NDAA will come together after the election." 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.
