Upcoming Elections in Idaho

Tuesday, May 19, 2026 - Primary Elections

Tuesday, November 3, 2026 - General Election

What are Primary Elections?

Primary elections are held in even-number years on the third Tuesday in May to pick party candidates for federal, state, and county offices. Candidates receiving the most votes in the primaries go on to run in the general election.

Your party affiliation affects which primary races you can vote in. In Idaho, each political party determines which voters can participate in its primary elections. Learn more about party affiliation.

Any voter can choose to vote on a non-partisan ballot, which includes ballot measures and judicial positions. Information about registration requirements, voting eligibility, election day, and other information can be found here.

What are General Elections?

Successful party candidates from the primary election and nominated at their party’s convention appear on the ballot as well as statewide constitutional amendments, initiatives, referendums, and some taxing district elections. In a general election, voters choose their preferred candidate from among those listed on the ballot. Voters will receive the same ballot based on their Legislative District, regardless of party affiliation.

  • Check your voter registration ahead of time to make sure it matches your current legal name, especially if you’ve recently changed it.
  • Register and vote using your current legal name.
  • Register to vote early, either online, by mail, or in person. Alternatively, you can register to vote in person at the polls on election day with your ID and proof of residence.
  • Identify your polling place and note the hours of operation.
  • Bring a photo ID with your current legal name.
  • If voting in person is uncomfortable for fear of being outed or because your gender marker does not match your identity, consider voting by absentee ballot.

Voting Scenarios

If your ID and voter registration match, you should have no issue.

If you need to re-register to vote with your new legal name, don’t worry. You can pre-register to vote up to 25 days prior to the election. You can also register in person at the polls on election day or during early voting with your ID and proof of residence.

If your gender identity and/or presentation does not match the gender marker on your ID, don’t worry. You have the right to cast a ballot. Ask for a Personal Identification Affidavit.

Gender discrepancies on ID are not a valid reason to deny a ballot. If you are not allowed to cast a ballot, ask for a Personal Identification Affidavit and request follow up instructions to make sure your vote gets counted.

Voting with a Criminal Conviction in Idaho

To be a successful voter, make sure to do the following:

  • Register to vote early, either online, by mail, or in person at least 25 days prior to the election. For in person early registration, you will need to visit your county clerk’s office.

Do you have a felony conviction?

If you are convicted of a felony, your right to vote is automatically restored once you complete your sentence, including prison time, any probation, parole, or extended supervision.

Do you have a misdemeanor conviction?

If you are convicted of a misdemeanor, you never lose your right to vote. If you think you will be in jail on Election Day, you can request an absentee ballot application, complete the form and send it to your County Clerk.

Absentee Ballot Process

To request an absentee ballot, you will need to submit an absentee ballot application online, apply in writing to the County Clerk, or, if you are incarcerated, request an absentee ballot application from jail administrators.

Complete the application form and personally sign it. Submit the form early enough that the County Clerk gets it at least 6 days before Election Day. Mail-in absentee ballots (not the absentee ballot application) must be received by 8:00 pm on Election Day.

Voting While Experiencing Homelessness

I am staying at a shelter - can I still vote?

Yes, you can use the shelter address as your home address to register to vote. If you register to vote early by mail, no proof of residency or photo ID is required, only your Social Security Number and you can simply list the shelter’s address as your residency/mail address.

OR you can obtain a proof of residency letter from the shelter you are staying at and register on Election Day. If you decide to register on Election Day, you will need to present a photo ID and proof of residency.

What if I don’t have a driver’s license or form of photo ID?

You can still vote! Make sure to register to vote 25 days before the election so that your registration is processed on time. On Election Day you can sign the Personal Identification Affidavit to prove your identity instead of showing your ID.

What if I don’t have an address?

If you don’t have an address, you can use the following options:

  • The address of a shelter you are currently staying at
  • The cross street or the spot where you usually sleep (for example, “9th and Main” or “Julia Davis Park”)

Helpful Tips

  • Indicate that you are currently experiencing homelessness if you use the courthouse or a cross street on your voter registration card to clarify the process of verifying an address.
  • Follow up with your County Clerk in person or over the phone to receive confirmation on where your precinct and polling place are located to ensure you know where to vote on Election Day. You can also do this online.
