Absentee Information


Registered Missourians who are unable to go to their polling place on Election Day, may vote absentee beginning six weeks prior to an election.

 Absentee voters must provide one of the following reasons for voting absentee:
  1. Absence on Election Day from the jurisdiction of the election authority in which such voter is registered to vote;
  2. Incapacity or confinement due to illness or physical disability on election day, including a person who is primarily responsible for the physical care of a person who is incapacitated or confined due to illness or disability and resides at the same address; 
  3. Religious belief or practice;
  4. Employment as an election authority or by an election authority at a location other than such voter’s polling place, a first responder, a health care worker, or a member of law enforcement;
  5. Incarceration, provided all qualifications for voting are retained.
  6. Certified participation in the address confidentiality program established under sections 589.660 to 589.681 because of safety concerns.

Voters can request absentee ballots in person, by fax, mail or email.  Relatives within the second degree (spouse, parents and children) may complete an absentee ballot application, in person, on behalf of the voter who wishes to vote absentee.

Absentee ballot requests must be received by the election authority no later than 5:00 p.m. on the second Wednesday prior to any election. Voters can vote by absentee in the office of the election authority until 5:00 p.m. the night before the election.

Voters requesting an absentee ballot by mail who have registered by mail and have not voted in person are required to submit a copy of their personal identification unless they provided a copy with their registration application. 

Examples of acceptable identification are:

  • A nonexpired Missouri driver or non-driver license;
  • A nonexpired military ID, including a veteran’s ID card;
  • A nonexpired United States passport; or
  • Another photo ID issued by the United States or the state of Missouri which is either not expired or expired after the date of the most recent general election.

This identification requirement, as well as the notary requirement for absentee ballots, does not apply to overseas voters, those on active military duty or members of their immediate family living with them or voters who are permanently disabled and their caregivers.
