Reconciliation is a legislative process of the United States Senate intended to allow consideration of a budget bill with debate limited to twenty hours under Senate rules. Because of this limited debate, reconciliation bills are not subject to the filibuster in the Senate. Reconciliation also exists in the United States House of Representatives, but because the House regularly passes rules that constrain debate and amendments, the process has had a less significant impact on that body.
A reconciliation instruction is a provision in a budget resolution directing one or more committees to submit legislation changing existing law in order to bring spending, revenues, or the debt ceiling into conformity with the budget resolution. The instructions specify the committees to which they apply, indicate the appropriate dollar changes to be achieved, and usually provide a deadline by which the legislation is to be reported or submitted.
A reconciliation bill is a bill containing changes in law recommended pursuant to reconciliation instructions in a budget resolution. If the instructions pertain to only one committee in a chamber, that committee reports the reconciliation bill. If the instructions pertain to more than one committee, the House Budget Committee reports an omnibus reconciliation bill, but it may not make substantive changes in the recommendations of the other committees.
