Absentee Voting

You may vote an absentee ballot by mail or in person at the St. Charles County Election Authority starting approximately six weeks before Election Day if one of the following applies:
  • Absent on Election Day from the jurisdiction in which you are registered
  • Incapacity or confinement due to illness or physical disability, including a person who is primarily responsible for the physical care of a person who is incapacitated or confined due to illness or disability
  • Religious belief or practice
  • Employment as an election judge
  • Active military or overseas civilian and immediate family living with you

Vote an absentee ballot in person:  You may vote an absentee ballot in person at the Election Authority's office.  Such voting begins approximately six weeks before an Election and continues until 5 p.m. the day before the Election.

Absentee ballot for a family member:  A family member within the 2nd degree may apply for the ballot in person to be mailed to the family member.

Applying for an absentee ballot by mail: You will need to request a ballot in writing, and you must reapply for a new ballot before each election.  If you have registered to vote by mail, proof of identification is required before an absentee ballot may be mailed to you.  After you receive your ballot, insert the voted ballot inside the provided return envelope, and a Notary must witness your signature on the Affidavit on the outside of the envelope.  Notary officials may perform this service free of charge for absentee voters.

Disabled:  You can request to be put on a list to receive your ballots by mail.  Initially download, complete and return the "Permanently Disabled Absentee Ballot Application" form, and then you will automatically be sent an Absentee Ballot Application before each subsequent Election, which you will then need to complete, sign and return if you wish to receive your ballot by mail for that Election.

Military and Overseas Civilian:  You may request an absentee ballot from the commanding officer or by contacting the Election Authority.  To vote on all ballot issues, you must be a registered voter or provide proof of identification.  You may download, complete and return the Federal Post Card Application Form. This form may also be used for an Overseas Civilian of the U.S. who claims an address within St. Charles County, Missouri.

The Affidavit Envelope does not have to be notarized for anyone requesting an absentee ballot because of sickness or disability, including a person who is primarily responsible for the physical care of a person who is incapacitated or confined due to illness or disability, or a resident of the State of Missouri or immediate family living with them who resides outside the boundaries of the United States or who is in active duty with the armed forces of the United States.

If you are hospitalized, within our county, after 5 p.m. on the Wednesday prior to an Election, you may call the Election Authority's office to request an absentee ballot.  A bi-partisan team of election judges will be sent to your hospital room to allow you to vote.

Written requests for Absentee ballot must be received in the Election Authority's office no later than 5:00 p.m. the Wednesday before any Election.  You may download, complete and return the "Application for Absentee Ballot for St. Charles County, MO"  or your request must contain the following information:

  • Your full name
  • Address where you live
  • Address where you would like the ballot to be mailed (if different)

  • Your political party preference, if you are applying for an August Primary ballot

If you are voting absentee, your ballot must be returned to the Election Authority office no later than 7:00 p.m. the day of the Election.  The Election Authority will only accept absentee ballots that are delivered via mail, registered carrier, or personally returned by the voter or a family member with the 2nd degree.
