Official voter resources
Make your Missouri voting plan
Use Missouri's official voter services to register, check your record, locate your polling place, request an absentee ballot, review photo identification, and confirm your local election authority's in-person absentee locations.
First steps
Start with these three actions
Plan in-person absentee or Election Day voting
Reason-based absentee voting begins September 22. No-excuse in-person absentee voting runs October 20 through 5 p.m. November 2 at locations designated by the local election authority. Election Day polls are open from 6 a.m. to 7 p.m.
Request and return an absentee ballot
A mail or fax request must reach the local election authority by 5 p.m. October 21. The completed ballot must reach the election authority by 7 p.m. November 3.

Election timeline
Reason-based absentee voting begins
The absentee period begins on the sixth Tuesday before the election. Before October 20, in-person absentee voters need an eligible reason, and a reason is required whenever requesting a ballot to return by mail.
Voter registration deadline
Registration is due by the fourth Wednesday before the election. A mail registration application must be postmarked by this date.
No-excuse in-person absentee voting begins
From the second Tuesday before the election through the day before Election Day, registered voters may vote an in-person absentee ballot without stating a reason at a location designated by the local election authority.
Mail or fax absentee request deadline
The local election authority must receive a mail or fax request by this deadline. Applications go to the appropriate local election authority, not the Secretary of State.
Write-in declaration deadline
A write-in candidate generally must file a declaration of intent with the proper election authority by this deadline.
In-person absentee voting ends
Absentee voting in the office of the local election authority is available until 5 p.m. on the day before the election.
General Election Day and absentee ballot receipt deadline
Polls are open from 6 a.m. to 7 p.m. Anyone in line at 7 p.m. may vote. The election authority must receive an absentee ballot by the close of polls.
Check the current rule: Missouri in-person voters should bring an acceptable photo ID: a qualifying Missouri driver or non-driver license, military ID, U.S. passport, or another qualifying federal or Missouri photo ID. A registered voter without one may cast a provisional ballot under the official verification rules. A reason is required when requesting a ballot to return by mail, and reason, identification, and notary rules have specific exceptions. Confirm the location and method with your local election authority.
5 certified statewide ballot measures
The Missouri Secretary of State confirms Amendments 3, 6, 7, and 8 and Proposition A for the November 3, 2026, general election. The summaries below track the official ballot titles and fair ballot language without predicting legal or fiscal outcomes.
- Amendment 3A yes vote would repeal the 2024 constitutional reproductive-health provision, permit abortion restrictions with stated exceptions, require consent provisions including parental or judicial consent for minors, and prohibit specified gender-transition procedures for minors with stated medical exceptions. A no vote would leave the 2024 provision in place.
- Amendment 6A yes vote would make the initiative and referendum process a fundamental right, limit legislative changes to voter-enacted or referendum-rejected laws, require an 80 percent vote in each legislative chamber for specified referrals, and preserve existing petition signature and statewide majority requirements. A no vote would leave current constitutional provisions in place.
- Amendment 7A yes vote would create the Show-Me Prosperity Fund as a permanent public endowment, restrict legislative access to the fund, and provide for eliminating state-imposed taxes if net investment earnings become sufficient. A no vote would not create the fund.
- Amendment 8A yes vote would place county sheriff elections and specified sheriff duties in the Constitution, limit removal of an elected sheriff to a quo warranto action initiated by the Attorney General, and recognize the office as part of the administration of justice. A no vote would leave current constitutional provisions unchanged.
- Proposition AA yes vote would approve House Bill No. 1 from the 2025 Second Extraordinary Session and its replacement congressional boundaries. A no vote would leave the congressional district boundaries enacted in 2022 in place.
1 statewide Supreme Court retention question
The Secretary of State's judicial certification lists Paul C. Wilson for the Missouri Supreme Court. That retention item is decided statewide. The five Court of Appeals judges are assigned to the Eastern, Southern, or Western District, and circuit and associate circuit judges are geographically limited, so those items are outside this statewide count.
