You can register at the Johnson County Auditor's Office during regular business hours, 8:00 a.m. - 5:00 p.m., Monday - Friday. If you have questions, we can help you at our office.

Register on Election Day

It is easier to vote if you register in advance. However, it is possible to register on Election Day or after the pre-registration deadline (15 days before election day) using the Election Day Registration procedure. This requires ID and proof of address.

Updating your registration

You will need to update your registration whenever you move, change your name, or change your political affiliation. Use the links above to update your registration online, or to print a Voter Registration Form.

The voter registration deadline is 15 days before any election. The safest thing to do is to update your registration as soon as you move. (We cannot accept address changes before you move; you need to wait until you move in and can get mail at your new address.)

You can still make changes within the county after the deadline. You can also register after the deadline using Election Day Registration procedures.

If you move to another county in Iowa, you should register in your new county and their Auditor's Office will update your record in the statewide voter system.

If you move out of Iowa, you are not required to cancel your registration in Johnson County. However, other jurisdictions may have rules about being registered in two places. We encourage you to complete the Voter Registration Cancellation Form and return it to our office. We can't accept cancellation requests by phone or email - the law requires a paper document with a signature.

College student voters

College students have a choice to register to vote at their home address or at their school address.

Voting From Your School Address:

Students attending college in Johnson County may register with their school address. If you reside in a dorm, please include the dorm name and room number (we don't need the street address for dorms). In the "Where You Receive Mail" portion, do not list your home address if you are intending to vote in Johnson County under your school address. If you live in an apartment, please remember to include your apartment number.

Voting From Your Permanent or Home Address:

If students choose to register or remain registered at their home address, they will have to vote in that county or vote by absentee ballot.

Early voting
Voting by mail

Iowa voters may not request mailed ballots until 70 days before an election. You cannot request a ballot for the November 5 General Election (presidential election) until August 27. Forms received before that date will be returned to the voter. (Overseas and military voters may request ballots at any time.) We are currently accepting requests for the September 10 University Heights special election ONLY.

Ballots may not be mailed until 20 days before an election. Iowa does not have permanent absentee status, so you must submit a new request form for each election. The deadline is 15 days before the election.

Steps to vote by mail:

  1. Print and complete an Absentee Ballot Request Form (Do not mail before August 27, except for University Heights voters voting in the September 10 special election.)  If you can't print, you can pick up a form, or you can call our office and we can mail you a form.

  2. Mail or hand deliver your request to our office (we need the hard copy paper form):

                  Johnson County Auditor
                  913 S Dubuque St, Suite 101
                  Iowa City, IA 52240

    Anyone may deliver a request form for another voter.

  3. Your ballot will be mailed to you. (Even if you hand deliver your form, we must mail your ballot.)

  4. Your ballot must be returned to our office by the time the polls close on Election Day. (This is a recent change in state law. Ballots postmarked before Election Day which reach our office after Election Day will no longer count.)

Voting at the Auditor's Office

Voters can cast an absentee ballot in person at the Johnson County Auditor's office beginning 20 days before any election, through the day before Election Day. Ballots must be voted in the office, you cannot take a ballot home with you.

On Election Day there is no in-person absentee voting at our office, and voters must go to their polling place.

Satellite voting

Under a recent change in state law, auditors may no longer schedule satellite sites on their own, and sites must be petitioned by the public.

Overseas and military voters

The Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) extends federal absentee voting rights to Service members, their eligible family members, and overseas citizens. There are special rules for requesting an absentee ballot for these voters. We encourage you to call our office or email [email protected] with questions about this program.

Voter lists

The Johnson County Auditor's Office can produce electronic voter lists for Johnson County or for any state legislative or school district which includes part of Johnson County. Congressional district and statewide lists may be ordered from the Secretary of State.

NOTE: Voter data is made available for political purposes only. Use of voter registration information for commercial purposes, such as debt collection or sales, or for any purpose other than those allowed by law is a serious misdemeanor. (Code of Iowa, Section 48A.39) Persons purchasing lists must specify their political purpose (for example, the name of a campaign or political organization). All list requests are kept on public file.


There is a minimum $10.00 charge for any voter list. Any list with less than 20,000 records will be the $10.00 minimum. For larger lists, the rate is $1.00 per 2,000 records. The voter file is constantly being updated, and actual costs are calculated at the time the list is prepared. A list of all active registered voters in the county usually cost between $45 and $50.

Voters may request copies of their own voter record at no charge, but still need to complete the Voter Registration Record Request Form.


Cash or check made payable to Johnson County Auditor's Office is due at the time the list is requested. (Unfortunately, we do not accept credit cards at this time).

For more information, contact our office.
