Voting Information for Missouri

Don’t miss your next election!

Your application for voter registration must be received by Oct. 7th. To vote by mail, voters must request an absentee ballot and provide an excuse.

For the duration of 2020, the state has extended its absentee voting excuse requirement to accommodate voters that have contracted or are at risk of contracting COVID-19. More info on what qualifies here.

Vote-by-mail systems are different in every state. It is critical that you follow directions and pay attention to the details, or your ballot could be challenged or even tossed.

The signature on your ballot must match your DMV signature, or signature that is on file with your voter registration if you do not have a state-issued ID. If your signature does not match, your ballot could be tossed.

Here are some important things to know about voting by mail in Missouri:

When you return your ballot, postage is prepaid. You do not need to add stamps.

Your state has a "received by" deadline of Tuesday, November 3rd. The post office suggests that ballots are mailed at least two weeks prior to make the "received by" deadline. Don't wait! You may also return your ballot via a delivery service, like FedEx or UPS, to ensure delivery date.

Your state does NOT offer voters a chance to address challenges to their ballot. Your ballot will be tossed if your signature does not match or you do not follow directions. Pay close attention to your state’s completed absentee ballot requirements so your vote is counted.

Be sure to sign your ballot in the presence of an official notary. They must also sign your ballot.

Presidential Primaries

No party affiliation is required at registration to participate in a primary. See Missouri Republican Party or Democratic Party sites for more details.

Statewide Primaries

Some congressional seats, state offices and constitutional amendments may be included on the ballot.

Early Voting + Absentee Voting



Early Voting Dates: Varies by County to Nov. 2nd

You can vote in person at your local election authority through Nov. 2nd at 5:00 p.m. before the election, using an absentee ballot. Visit your local election authority’s website for the start date.

To vote absentee by mail, first you’ll need to apply for an absentee ballot no later than Oct. 21st 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 ballot.

During 2020, the state has extended its absentee voting excuse requirement to accommodate voters that have contracted or are at risk of contracting COVID-19. Similarly, voters that qualify for an absentee ballot because they have or are at risk of contracting COVID-19 do not have to obtain a notary or witness signature on their ballot.

Whether it’s in-person or by-mail, you’ll need to give an excuse to vote by absentee ballot. Info here on what qualifies.

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