Mahaska County Voter Registration and Election Day Information

OSKALOOSA — Mahaska County Auditor and Commissioner of Elections is asking that eligible voters in Mahaska County who have not yet registered or changed their Mahaska County address with the Auditor’s Office consider doing so before the early voter registration deadline of 5:00 p.m. Monday, October 24, 2022. After October 24, new
registrations in Mahaska County, will be required to follow the same process as those registering on election day. If voting at the polls, any Mahaska County voter who has not changed their address with the Auditor’s Office prior to the deadline, will need to change their address at their new voting precinct on election day and show proof of residency and ID.

Eligible persons are allowed the right to register to vote and cast a ballot on Election Day if they are able to provide proof of both their identity and residency at the polls. The best form of ID is a valid Iowa Driver’s license with current address.

Pre-registered voters are required to provide an approved form of identification at the polling place before receiving and casting a regular ballot. Voters who are not pre-registered – such as voters registering to vote on election day – and voters changing precincts must also provide proof of residence. A voter who is unable to provide an approved form of identification (or prove residence if required):

  1. May have the voter’s identity / residence attested to by another registered voter in the precinct,
  2. Prove identity and residence using Election Day Registration documents, or
  3. Cast a provisional ballot and provide proof of identity / residence at the county auditor’s office by Noon, Monday, November 14.

Election Day Registrant attesters must provide an approved form of identification and complete the attester’s oath. For additional information about providing proof of identity and / or residence visit: or call 641-673-7148.

Voter Registration forms can be obtained online at or or at the Auditor’s office. Registrations should be mailed to Mahaska County Auditor, 106 South 1st Street, Oskaloosa, IA 52577. The Auditor’s office is open weekdays from 8:00 a.m. to 4:30 p.m. Any questions concerning this process or about the General Election can be answered by calling 641-673-7148.
