How Congress Counts Electoral Votes: Procedures

Updated: October 27, 2026

Introduction: How Congress Counts Electoral Votes

Congress’s count is the final federal step in identifying the president and vice president chosen by the Electoral College. Voters cast ballots on Election Day, but electors meet in their states in December and cast separate ballots for president and vice president. Congress then convenes in a joint session on January 6 after the election, unless that date falls on a Sunday, to count the state-certified electoral votes. The procedure is not a new election: the Electoral Count Reform Act of 2022 sharply limits Congress’s role to counting validly appointed electors under rules set by the Constitution and federal law.

• 538 total electoral votes, based on 435 House seats, 100 senators and three votes for the District of Columbia
• 270 electoral votes required for a majority when all 538 are appointed
• January 6 date Congress meets to count electoral votes under current law, with a Sunday exception
• Two hours maximum debate in each chamber on a qualifying objection

Legal Framework Governing Electoral Vote Counting

The 12th Amendment, ratified in 1804, requires the president of the Senate to open the certificates “in the presence of the Senate and House of Representatives” and have the votes counted. The Electoral Count Act of 1887 supplied statutory procedures after the disputed 1876 election. Congress revised that framework through the Electoral Count Reform Act of 2022, enacted as Division P of Public Law 117-328. The amended law governs modern counts, including the 2025 count of the 2024 election.

Key Legal Provisions

• 12th Amendment: Electors cast distinct ballots for president and vice president. A majority of appointed electors is needed to win; if no one has that majority, the amendment assigns the presidential choice to the House and the vice-presidential choice to the Senate.
• Electoral Count Reform Act: Sets January 6 for the joint session, establishes the objection threshold and clarifies that the vice president’s duties are ministerial. An objection must be written and signed by at least one-fifth of each chamber’s members.
• Federal election deadlines: States appoint electors under state law, and federal law sets a December meeting date for electors and a process for states to issue certificates. The governor generally issues the certificate of ascertainment identifying appointed electors.
• Presidential succession law: The Presidential Succession Act of 1947 addresses succession if a president cannot serve; it does not set the voting rules for a contingent election, which come from the 12th Amendment.

The distinction matters: Congress does not decide which candidate won each state from scratch. State election and certification processes determine the slate of electors, while federal law specifies how Congress counts the certificates and handles a properly raised objection.

Step-by-Step Procedures During the Joint Session

At 1 p.m. on January 6, the House and Senate assemble in the House chamber, with the vice president presiding as president of the Senate. The Electoral Count Reform Act directs the chambers to meet on that date unless it is a Sunday, in which case the session takes place the following day. The House appoints tellers, and the certificates are taken up in alphabetical order by state.

Overview of the Counting Process

• Certificates opened: The vice president opens the certificates and papers purporting to be electoral votes, in the order prescribed by law.
• Votes read and recorded: Four tellers—two House members and two senators—read and tally the votes. The count records each state’s votes for president and vice president separately.
• Objection considered: A member may submit a written objection during the relevant state’s presentation, but it must carry signatures from at least one-fifth of the House and one-fifth of the Senate. With the House at 435 voting members, the threshold is 87 representatives; with 100 senators, it is 20 senators.
• Separate chamber action: If an objection meets the threshold, the joint session suspends and each chamber may debate for no more than two hours. Each chamber then votes separately.
• Count completed: The chambers reconvene, the count continues, and the presiding officer announces the final totals and whether a majority has been reached.

The count can take longer when objections qualify, but the statute does not set a general one- or two-hour limit for the entire session. The two-hour cap applies to debate on each objection in each chamber, not to opening and reading all certificates.

Handling Objections and Disputed Electoral Votes

Objections have been made in modern counts, but they rarely alter the result. In 2005, the House and Senate separately debated an objection to Ohio’s 20 electoral votes; both rejected it. On January 6, 2021, members objected to Arizona’s 11 votes and Pennsylvania’s 20 votes. The Senate rejected both objections, and the House rejected them as well. The attack on the Capitol interrupted the count, which resumed that evening.

Criteria and Outcomes of Objections

• An objection must be in writing and signed by at least one-fifth of the House and one-fifth of the Senate—not merely one member of each chamber.
• Under the 2022 law, an objection may be based on a limited ground: that electors were not lawfully certified under the relevant federal requirements, or that one or more electoral votes were not “regularly given.”
• Both chambers must agree to sustain an objection for the challenged vote or votes to be excluded. If either chamber votes against it, the count proceeds without excluding them.
• The statute directs Congress to give conclusive effect to a state’s certificate of ascertainment issued under state law, subject to the law’s defined procedures and judicial review provisions.

The change from one signer in each chamber to a one-fifth threshold was designed to limit objections that trigger debate. It did not give Congress a general power to revisit state vote totals or choose a different slate of electors.

Contingent Elections: What Happens If No Majority?

If no presidential candidate receives a majority of appointed electors, the 12th Amendment sends the presidential choice to the House. The House chooses from the three candidates with the most electoral votes. This is not a vote of all 435 representatives: each state delegation casts one vote, and at least 26 states are needed to elect a president. The District of Columbia has no vote in this House procedure.

House and Senate Roles in a Contingent Election

• House chooses president: A quorum requires representation from two-thirds of the states, or 34 state delegations. A candidate must receive a majority of all states, currently 26.
• Senate chooses vice president: Senators choose between the two vice-presidential candidates with the highest electoral totals. A quorum is two-thirds of the full Senate, and a majority of the whole Senate—51 votes in a 100-member chamber—is required.
• Different voting rules: In the House, each state delegation has one vote; in the Senate, each senator casts an individual vote. A tied House delegation cannot contribute a state vote for either candidate.
• Inauguration deadline: The 20th Amendment sets noon on January 20 as the start of the new presidential term. If no president-elect has qualified by then, the vice president-elect acts as president if qualified; otherwise the succession statute applies.

The last contingent presidential election was in 1824. Andrew Jackson won more popular and electoral votes than any rival but lacked an electoral majority; the House selected John Quincy Adams in February 1825. The Senate has selected a vice president through a contingent election once, in 1837, choosing Richard Mentor Johnson.

Role of the Vice President and Congressional Officers

The vice president presides over the joint session but does not decide which votes count. The Electoral Count Reform Act expressly states that the president of the Senate has no power to determine, accept, reject, or otherwise adjudicate disputes over electors. That clarification followed the January 6, 2021, pressure campaign urging Vice President Mike Pence to reject electoral votes; Pence declined, and the count proceeded under the law then in force.

Congressional Officers and Their Duties

• Four tellers: Two members from each chamber read the certificates and prepare the tally.
• Clerk of the House and Secretary of the Senate: Assist with the official papers, records and administration of the session.
• Sergeants at Arms: The House and Senate officers help maintain order and carry out chamber instructions.
• Presiding officer: The vice president announces the state-by-state results and the final count but has no unilateral vote or veto in the count.

Congress can alter the result only through the procedures provided by the Constitution and statute, including a qualifying objection approved by both chambers—not through a ruling by the vice president.

Frequently asked questions

Key takeaways

• The 12th Amendment and the Electoral Count Reform Act of 2022 govern the count; the 2022 law amended the framework originally enacted in 1887.
• Congress meets in joint session on January 6 at 1 p.m., unless January 6 is Sunday, to count certificates state by state.
• A written objection needs signatures from one-fifth of each chamber—87 House members and 20 senators when the chambers have their full membership—and both chambers must sustain it to exclude votes.
• A majority is 270 of 538 electoral votes when all electors are appointed. Without a majority, the House chooses the president by state delegation and the Senate chooses the vice president by individual senator votes.
• The vice president presides but cannot independently accept or reject electoral votes.

Conclusion

Congress’s electoral-vote count is a defined constitutional procedure, not an opportunity for lawmakers or the vice president to conduct a second election. The 2022 Electoral Count Reform Act sets an 87-member House and 20-senator signature threshold for objections, caps debate at two hours per chamber for each qualifying objection, and makes the vice president’s role ministerial. If no candidate reaches 270 electoral votes, the 12th Amendment supplies a separate fallback: the House elects the president through state votes, while the Senate elects the vice president. Those rules connect state certifications to the peaceful transfer of power while giving Congress a narrow, structured role in resolving disputes.
