Conference Report

A document produced by a conference committee that reconciles differences between House and Senate versions of a bill before final approval.

Updated April 23, 2026


How It Works

When the United States Congress passes legislation, both the House of Representatives and the Senate often create their own versions of a bill. These versions may differ in wording, provisions, or funding levels. To resolve these discrepancies, a conference committee composed of members from both chambers is convened. The committee negotiates to reconcile the differences and produces a conference report—a single, unified version of the bill that reflects compromises acceptable to both the House and Senate.

What It Means in Practice

The conference report is crucial because it represents the final legislative language that both chambers must approve before a bill can be sent to the President for signature. After the conference committee submits the report, both the House and Senate vote on it without further amendments. Approval of the conference report signifies that both chambers agree on the legislation’s final form.

Why It Matters

The conference report ensures legislative coherence and prevents conflicting laws from being enacted. Without this reconciliation process, the House and Senate could pass incompatible bills, leading to legal confusion or administrative difficulties. Additionally, the conference committee process fosters bipartisan negotiation and compromise, which is essential in a bicameral legislature.

Conference Report vs Committee Report

A common misconception is to confuse a conference report with a committee report. While both are documents related to legislation, they serve different purposes. A committee report is prepared by a standing committee that initially reviews and amends a bill before it reaches the floor. In contrast, a conference report comes at the end of the legislative process and reconciles differences between the two chambers' versions of a bill.

Real-World Examples

A prominent example of a conference report’s role was during the passage of the Affordable Care Act in 2010. After the House and Senate passed different versions, a conference committee worked out the final provisions. The conference report was then approved by both chambers before the bill was signed into law.

Common Misconceptions

Some believe that conference reports can be amended during the final vote, but this is not the case. Once the conference report is submitted, it must be accepted or rejected as is. Another misconception is that the conference committee can introduce entirely new provisions unrelated to the original bills; however, their role is to reconcile existing differences, not to create new legislative content.

Example

During the 2010 healthcare reform, the conference report reconciled differences between the House and Senate versions before the bill became law.
