What is budget reconciliation?
Budget reconciliation is a fast-track process that lets Congress pass certain tax, spending, and debt-limit legislation with a simple majority in the Senate, because debate is capped by law and no filibuster is possible.

Votes needed: A simple majority in each chamber; 60 votes only to waive the Byrd rule
What budget reconciliation is
Reconciliation is the exception to the Senate's 60-vote reality. Created by the Congressional Budget Act of 1974, it lets Congress adjust spending, revenue, and the debt limit through a bill with special protection: Senate debate is capped at 20 hours by statute (senate.gov). A process with a legal debate limit cannot be filibustered, so a reconciliation bill needs a simple majority, 51 votes or 50 plus the vice president, instead of the 60 needed to break a filibuster.
How it starts
Reconciliation begins with a budget resolution. Both chambers adopt a budget blueprint containing reconciliation instructions, directions to named committees to report legislation meeting fiscal targets. The committees' products are assembled into one reconciliation bill, and that bill rides the fast track. The supply is limited: a budget resolution supports only a small number of reconciliation bills, so a majority party typically gets one big swing per budget cycle, not many.
The Byrd rule
The price of the fast track is the Byrd rule, adopted in 1985 and named for Senator Robert Byrd. It lets any senator raise a point of order against "extraneous" provisions: language with no real budget effect, provisions whose fiscal impact is merely incidental to a broader policy change, anything touching Social Security, and provisions that raise deficits beyond the budget window (senate.gov). The Senate parliamentarian advises on what qualifies, which is why whole sections of reconciliation bills die in what the chamber calls the Byrd bath. Setting the rule aside takes 60 votes, the very threshold reconciliation exists to avoid.
Reconciliation in the 119th Congress
The current record shows the process working as designed. On June 5, 2026, the Senate passed S. 2, a reconciliation bill moving under that budget cycle's instructions, 52 to 47, a margin that would have been hopeless against a filibuster. The same day shows budget enforcement's teeth: senators moved to waive budget rules blocking their amendments, and every such motion failed despite majority support, including the Coons motion at 54 to 45, short of the required 60.
Vote-a-rama
When the 20 hours of debate expire, senators may still offer amendments, just without debate. The Senate then votes back to back for hours, a marathon nicknamed the vote-a-rama, and the roll calls pile up in the record. Most amendments fail. For senators, a vote-a-rama is a forced tour of hard votes; for a vote tracker, it is the densest data of the year. Laws passed by reconciliation include the 2017 tax law and the 2022 Inflation Reduction Act.

Common questions
Reconciliation is an expedited process under the Congressional Budget Act of 1974 for legislation changing spending, revenue, or the debt limit. Senate debate on a reconciliation bill is capped at 20 hours by statute, so it cannot be filibustered and passes with a simple majority instead of 60 votes.
A Senate rule, adopted in 1985, that strips extraneous material from reconciliation bills: provisions without real budget effects, changes to Social Security, or deficit increases beyond the budget window. Any senator can raise the point of order, and waiving it takes 60 votes.
A simple majority: 51 of 100 senators, or 50 plus the vice president breaking a tie. On June 5, 2026, the Senate passed the S. 2 reconciliation bill 52 to 47, a margin far below the 60 votes ordinary legislation needs to overcome a filibuster.
