How a Bill Becomes Law in 2026: The Real Process

The textbook version of how a bill becomes law — the cartoon where both chambers pass an identical bill and the President signs it — is a real route. It is not the only one, and the Congressional Research Service is direct about how loosely it describes practice: "the process by which a bill can become law is rarely predictable and can vary significantly from bill to bill. In fact, for many bills, the process will not follow the sequence of congressional stages that are often understood to make up the legislative process."

This guide follows the sequence anyway, because it is the frame everything else gets measured against, and stops at each step to say what the rules actually provide.

Step 1: Introduction

CRS describes introduction in one sentence per chamber: "In the House, a bill is introduced when it is submitted electronically or dropped in the hopper (a wooden box on the House floor). In the Senate, the bill is submitted to clerks on the Senate floor." Two methods, both current.

On introduction the measure "will receive a designation based on the chamber of introduction, for example, H.R. or H.J.Res. for House-originated bills or joint resolutions and S. or S.J.Res. for Senate-originated measures." H.R. is a House bill; H.J.Res. is a House joint resolution. They are different things that both start in the House.

A bill that becomes law is issued a public law number. S. 1884, the Holocaust Expropriated Art Recovery Act of 2025, became Public Law 119-82 on April 13, 2026. The 119th Congress has issued 102 public laws so far, numbered 119-1 through 119-102.

Introduction commits nothing beyond the number. CRS records that "each committee receives many bill referrals over the course of a Congress—far more than the panel is capable of pursuing in any detail," and that committees "do not formally consider each of these referred bills."

Step 2: Committee Referral

Once a bill is introduced, "it is typically referred to the committee (or committees) in that chamber with jurisdiction over its elements." In the House a bill can go to several committees at once, and "one of those committees will be designated the primary committee of jurisdiction and will likely take the lead on any action that may occur." In the Senate, "in almost all cases, the bill is referred to only the committee with jurisdiction over the issue that predominates in the bill" — though "in a limited number of cases, a bill might not be referred to committee, but instead be placed directly on the Senate Calendar of Business through a series of procedural steps on the floor."

The chair decides what happens next: "the committee's chair has the chief agenda-setting authority for the committee." CRS adds one qualification worth keeping: "Committees are not limited, however, to consideration of measures referred to them and may initiate legislative action on their own."

Committee inaction is not the end of the road. Clause 2 of House Rule XV provides that a member "may present to the Clerk a motion in writing to discharge—(A) a committee from consideration of a public bill or public resolution that has been referred to it for 30 legislative days." When "a majority of the total membership of the House" — construed since a 1936 ruling by Speaker Byrns to mean 218 members — signs that motion, "it shall be entered on the Journal, published with the signatories thereto in the Record, and referred to the Calendar of Motions to Discharge Committees." Our guide to the discharge petition covers the procedure in detail; how often that threshold is actually reached is a different question from whether the mechanism exists.

Step 3: Subcommittee Review and Hearings

Whether a subcommittee handles a bill first is not fixed by any rule. CRS records that "the extent to which subcommittees play a formal role in policymaking—for example, by holding hearings or marking up legislation prior to full committee consideration—varies by chamber and by committee tradition and practice," and that "whatever role a full committee allows its subcommittees to play, subcommittees cannot report legislation to the chamber; only full committees may do so." A committee "may conduct hearings on a bill to provide committee members and the public an opportunity to hear from selected parties (e.g., a federal agency or organized interest) about the bill's strengths and weaknesses."

Step 4: Markup

If a committee "wants to formally recommend that the bill receive consideration from its parent chamber, it will hold a markup on the bill, at which committee members vote on any proposed amendments." The markup "concludes when the committee agrees, by majority vote, to report the bill (with any recommended changes adopted in the markup) to its chamber." What emerges is the bill with those changes in it.

A reported bill is, in CRS's words, "often accompanied by a committee report". That document has a life beyond the committee: CRS's survey of statutory interpretation notes that "some judges have suggested certain forms of legislative history are more reliable than others, with committee reports providing stronger evidence of Congress's understanding of the law than individual floor statements from non-sponsors, for example."

Step 5: Scheduling and the Rules Committee (House)

"In the House, majority party leaders generally decide which bills will receive floor consideration; typically, they schedule a bill for a type of streamlined floor consideration, or instead ask the Rules Committee to propose a set of tailored parameters for floor consideration." A special rule is "a simple House resolution (an H. Res.)" adopted case by case, and CRS lists the "common provisions found in a special rule": "the identification of the text to be considered, a specified period for general debate, and limits on the amendments that can be offered on the floor." The committee "could report a special rule that places few restrictions at all on amending. Typically, however, the special rule will allow only specified predetermined amendments to be offered or may instead preclude floor amendments altogether." The committee itself "generally operates as an arm of the majority party leadership, and majority party members outnumber minority party members, nine to four."

A special rule is one route to the floor, and not the busiest one. CRS records that "in the House, most bills that receive consideration do so under a procedure called 'suspension of the rules,' which limits debate to 40 minutes and prohibits floor amendments, but requires two-thirds of Members voting to agree." Only then does it add that "most other bills are considered under tailored debate and amending parameters set by the terms of a special rule reported by the House Rules Committee (which often operates as an arm of the majority party leadership)." Under suspension, "there is no requirement that a bill must be reported from committee before the House can consider it."

The Rules Committee is also itself dischargeable. The same clause 2 of Rule XV reaches "the Committee on Rules from consideration of a resolution that has been referred to it for seven legislative days and that proposes a special order of business for the consideration of a public bill or public resolution that has been reported by a committee or has been referred to a committee for 30 legislative days" — on the same 218 signatures. The Senate reaches its floor by a different route entirely: bills there "are brought to the floor only after the Senate agrees to a motion (typically offered by the majority leader) to proceed to a specific bill or, alternatively, if no Senator objects to a unanimous consent request to bring it up."

Step 6: Floor Consideration and Debate

House floor debate runs on the parameters the rule sets, which include "a specified period for general debate." The House "first considers that special rule itself on the House floor, for approximately one hour," and "only after its adoption will the House then proceed to" the bill. After debate and any amendments, "the House then typically votes on a motion to recommit offered by a minority party member before proceeding to a final vote on passage."

The Senate works differently, and CRS names the reason: "A defining feature of Senate floor consideration is that no rule permits a numerical majority to end debate and proceed to a final vote on most questions (e.g., a bill or amendment). Thus, Senators may wage a filibuster, effectively threatening extended debate or other actions that would delay or prevent a final vote." The way out is cloture. Supporters "can file a cloture motion, signed by at least 16 Senators. Two days of session later, Senators vote on the cloture motion. If three-fifths—usually 60 Senators—agree, then further consideration of the bill is limited to 30 hours." Senate Rule XXII states the threshold itself, and states its own exception in the same sentence: debate closes if the question is "decided in the affirmative by three-fifths of the Senators duly chosen and sworn—except on a measure or motion to amend the Senate rules, in which case the necessary affirmative vote shall be two-thirds of the Senators present and voting."

That machinery is not the Senate's only route. CRS: "frequently the Senate decides it can more effectively act by putting aside the formal rules and instead agreeing—by unanimous consent—to tailored parameters on debate and amending." The Senate's own reference page says the same of outcomes: "much of Senate business is conducted by unanimous consent, in which a measure passes so long as no senator objects." Our guide to unanimous consent covers what a single objection does.

Step 7: Voting

In the House, a member's request for a recorded vote is granted when it is "supported by at least one-fifth of a quorum," and the House Manual states what that means in members: "in a full House (total membership of 435), a recorded vote is ordered by one-fifth of a quorum (44), but in the Committee of the Whole a recorded vote is ordered by 25 (clause 6(e) of rule XVIII)." Votes are taken by electronic device, and clause 2(a) of Rule XX provides that "the minimum time for a record vote or quorum call by electronic device shall be 15 minutes" — a minimum, not a fixed window, which clause 9(a) lets the Speaker cut "to not less than two minutes" on a question that follows another electronic vote.

The Senate votes by calling the roll. Senate Rule XII provides that "when the yeas and nays are ordered, the names of Senators shall be called alphabetically; and each Senator shall, without debate, declare his assent or dissent to the question." The Senate takes a roll-call vote "if one-fifth of a quorum of senators request it"; otherwise a question can be decided on a voice vote, in which "the names of the senators and the tally of votes are not recorded." Our guide to voice votes and roll calls covers each method and what it leaves in the record.

Step 8: Resolving Differences Between the Chambers

For a bill to become law, both chambers must agree to identical text. CRS: "One chamber frequently agrees to a bill—without changes—that was sent to it by the other, but sometimes a chamber proposes changes to a bill sent to it by the other." When there are changes, there are two routes.

Amendments between the houses. "A back-and-forth trading of alternative proposals," also called amendment exchange or ping-pong. "For the bill to have a chance of becoming law, one chamber must eventually agree to the proposal that the other chamber sent it."

Conference committee. "Sometimes, the resolution of differences between the House and Senate proposals may instead be accomplished through a conference committee" — a temporary committee of conferees "drawn primarily from the standing committee(s) with jurisdiction over the bill," whose compromise "is embodied in a conference report." A conference report "may be considered under the same procedures used for other business, though it cannot be amended."

Resolving differences is not budget reconciliation, which is a separate statutory process, described below.

Step 9: Enrollment and Presidential Action

Two different printings happen at two different points, and the statute assigns them to different officers. Under 1 U.S.C. 106, when a bill "passes either House" it is printed and "such printed copy shall be called the engrossed bill"; the engrossed bill "shall be signed by the Clerk of the House or the Secretary of the Senate, and shall be sent to the other House." Once it "shall have passed both Houses, it shall be printed and shall then be called the enrolled bill... and shall be signed by the presiding officers of both Houses and sent to the President of the United States."

1 U.S.C. 107 governs what it is printed on: enrolled bills "shall be printed on parchment or paper of suitable quality as shall be determined by the Joint Committee on Printing." Parchment is one of two options the statute allows. Congress has also repeatedly waived both sections outright. The waiver enacted on October 27, 1990 covers "any reconciliation bill, appropriation bill, or continuing resolution of the One Hundred First Congress", sends those to the President as a hand enrollment that "shall be in such form as the Committee on House Administration of the House of Representatives certifies to be a true enrollment," and then has the Clerk of the House "prepare a printed enrollment of the bill or joint resolution as in the case of a bill or joint resolution to which sections 106 and 107 of title 1, United States Code, apply" once it is enacted. A waiver enacted on November 20, 1995 reached "A debt limit extension measure" as well; there the certifying body is named as the Committee on House Oversight.

Article I, Section 7 then sets out every outcome:

1. Signature. "If he approve he shall sign it."
2. Veto. "If not he shall return it, with his Objections to that House in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it." A returned bill becomes law only if two thirds of each chamber agrees to pass it again — and those votes must be recorded: "in all such Cases the Votes of both Houses shall be determined by yeas and Nays, and the Names of the Persons voting for and against the Bill shall be entered on the Journal of each House respectively." CRS notes that "successful overrides of presidential vetoes are rare."
3. Inaction while Congress sits. "If any Bill shall not be returned by the President within ten Days (Sundays excepted) after it shall have been presented to him, the Same shall be a Law, in like Manner as if he had signed it."
4. Pocket veto. The same sentence carries the exception: "unless the Congress by their Adjournment prevent its Return, in which Case it shall not be a Law." Whether a particular adjournment "prevents" a return is contested rather than settled. CRS records that the 1929 Pocket Veto Case's statement about delivering a veto message to a legislative agent "was dicta and not the central holding of the case," and that when President Ford claimed five pocket vetoes in 1974 he returned the bills anyway — a protective return, in which "the President claims the power of pocket veto but, at the same time, returns the bill to Congress for a possible override." Congress treated them as ordinary returns and acted on one: "both Houses overrode the veto of the Vocational Rehabilitation Act Amendments: the House on November 20 and the Senate on November 21. Nevertheless, the Administration refused to promulgate it as a law."

Budget Reconciliation: The Simple-Majority Path

Cloture normally puts a three-fifths threshold in front of Senate legislation. Budget reconciliation is the route around it, and CRS explains why in mechanical terms: "a distinctive feature of reconciliation is that debate time is limited in the Senate, which means cloture (and its requisite three-fifths majority vote) is not necessary to reach a vote on final passage." The limit is statutory, and it binds the Senate: 2 U.S.C. 641(e)(2) provides that "Debate in the Senate on any reconciliation bill reported under subsection (b), and all amendments thereto and debatable motions and appeals in connection therewith, shall be limited to not more than 20 hours." That is what puts a final vote within reach of a simple majority.

Reconciliation is a two-phase process built on a budget resolution, and its directives come in three kinds: "to change laws providing for spending, to change laws providing for revenues, and to change the public debt limit."

It is not limited to one bill per budget resolution. CRS: "no more than one reconciliation bill may include provisions in response to each type of instruction in one budget resolution, for a maximum of three reconciliation bills. In practice, Congress has generally combined the reconciliation submissions from every committee into a single, omnibus reconciliation measure."

Four points of order bind the contents, and CRS sorts them by where they apply. Two apply in both chambers: "amendments to reconciliation legislation cannot increase the deficit" under section 310(d) of the Budget Act, and "reconciliation legislation cannot amend the Social Security program" under section 310(g). The statute states that second one broadly — 2 U.S.C. 641(g) bars any reconciliation bill "that contains recommendations with respect to the old-age, survivors, and disability insurance program established under title II of the Social Security Act", a bar on OASDI recommendations of any kind, not only on benefit levels. Two more apply in the Senate only. The Byrd rule, section 313, prohibits matter "extraneous to the instructions to a committee", and 2 U.S.C. 644 makes a provision extraneous if, among other tests, "it produces changes in outlays or revenues which are merely incidental to the non-budgetary components of the provision". And section 310(e) requires amendments to be germane, which is otherwise unusual: "in general, the standing rules of the Senate do not impose subject matter limitations on amendments to legislation."

CRS's appendix lists every reconciliation measure Congress has considered since 1980. The enacted ones include the Economic Growth and Tax Relief Reconciliation Act of 2001 (P.L. 107-16), the Jobs and Growth Tax Relief Reconciliation Act of 2003 (P.L. 108-27), the Health Care and Education Reconciliation Act of 2010 (P.L. 111-152), the FY2018 reconciliation law (P.L. 115-97), the American Rescue Plan Act of 2021 (P.L. 117-2), the FY2022 reconciliation law (P.L. 117-169) and, in this Congress, the FY2025 reconciliation law (P.L. 119-21), enacted July 4, 2025. Three of those go by names that are not their legal titles. CRS records that "the short titles for some reconciliation measures were omitted or struck pursuant to points of order and are referred to by other means," and names among them the FY2018 law (P.L. 115-97), "sometimes referred to as the Tax Cuts and Jobs Act"; the FY2022 law (P.L. 117-169), "sometimes referred to as the Inflation Reduction Act"; and the FY2025 law (P.L. 119-21), "sometimes referred to as the One Big Beautiful Bill Act."

How LegislationPatch Tracks the Process

LegislationPatch reads the Congress.gov API to establish where each bill stands. A bill's stage is derived from its action history rather than from its latest action line, and the labels the site uses are the steps above: Introduced, In Committee, On House Calendar or On Senate Calendar depending on the bill’s origin chamber, Passed House, Passed Senate, and Signed into Law. The date shown beside a stage is the most recent action Congress.gov records for that bill, not the date the stage was reached: our refresh script bumps it on any new activity, including housekeeping actions that advance no stage, because it is also the key the bill list sorts on.

For bills with recorded votes, roll-call results come from the Clerk of the House for House votes and from Senate.gov for Senate votes — the chambers' own published records rather than aggregated third-party data.
