At a glance
You must register before the deadline below.
Without photo ID, vote a provisional ballot that counts if you return with ID by 7 p.m. that day or your signature matches. No ID? Ask your election office whether it offers a free one for voting. First-time voters who registered by mail may need to show ID under federal law.
Excuses: absent from jurisdiction, illness/disability (or caregiver), religious belief, election worker/first responders/health care/law enforcement, incarceration with voting rights, ACP participant Return deadline: received by 7 p.m. Nov 3 (close of polls).
No-excuse in-person absentee Oct 20 - Nov 2 (second Tuesday before through day before; photo ID required)
Since HB 1871 took effect Aug 28, 2026, most people on parole or felony probation can vote; those convicted of certain serious felonies (e.g. murder, first/second-degree assault) remain barred until probation/parole ends.

Where the road gets harder
Every rule is a cost, and it doesn't fall on everyone the same. A deadline, a document or a trip to an office is easy for some people and a real obstacle for others: people who work hourly jobs, move often, live far from an office, don't drive, or have a disability. Here is what that looks like in Missouri.
- Registration closes before Election Day (in person: Wednesday, October 7). Miss it and you can't vote in this election. If you've moved, your registration may need updating by then too.
- Registration isn't automatic. Each person has to sign up on their own, which leaves out people who don't know the rules or move often.
- You need an accepted reason to vote by mail. Excuses: absent from jurisdiction, illness/disability (or caregiver), religious belief, election worker/first responders/health care/law enforcement, incarceration with voting rights, ACP participant. Everyone else votes in person.
- A mail ballot envelope needs a witness or notary signature, an extra step that is harder for people who live alone or are homebound.
- Mail ballots have to arrive by Election Day; a postmark isn't enough. A ballot mailed in the last days can arrive too late and won't count, so return it in person if it's close.
- After a felony conviction: Since HB 1871 took effect Aug 28, 2026, most people on parole or felony probation can vote; those convicted of certain serious felonies (e.g. murder, first/second-degree assault) remain barred until probation/parole ends.
- Missouri's 2022 election law established a photo ID requirement at the polls; a state judge left it in place in November 2024 after finding challengers lacked standing.Source: KSMU / Missouri Independent
