Early Voting + Absentee Voting

Early Voting Dates: Jan. 19th - March 1st

You can vote in person at your local election authority from Jan. 19th to March 1st at 5:00 p.m. before the election, using an absentee ballot. Visit your local election authority’s website for the start date. You do not need a qualifying excuse to vote with a mail-in ballot in person due to COVID-19.

Due to COVID-19, Missouri has two vote by mail options.

All voters can request a mail-in ballot to reduce the risk and transmission of COVID-19. If you request a mail-in ballot you must have it notarized prior to returning it. Voters with qualifying excuses are asked to request absentee ballots. In this case, if your excuse is being high risk of COVID-19 or coronavirus 2, you do not need to have your ballot notarized.

In either case, to vote by mail, first you’ll need to apply for a ballot no later than Feb. 17th at 5:00 pm. Then, when you complete your absentee ballot, it must be received by Election Day. If you have not voted in-person at your current address, you’ll need to submit a copy of your photo I.D. with address and signature with your application.

Absentee ballot requests by-mail open 90 days prior to any election. Applicants must apply for each election.
