Voter guide to Montana’s 2026 general election

Key takeaways

  • Confirm the official 2026 election calendar.
  • Check and update voter registration information.
  • Review official ballot information tied to your address.
  • Verify the rules for your chosen voting method.
  • Follow official instructions for returning a ballot.

Montana’s 2026 general election will give voters an opportunity to cast ballots in the contests and on the questions listed for them. A voting plan should begin with four items: the official election calendar, registration status, the ballot connected to the voter’s address and the rules for the voting method the voter intends to use.

Exact deadlines and procedures matter. Voters should confirm each detail with Montana election administrators rather than relying on information remembered from an earlier election.

Start with the election calendar

First, confirm the date of the 2026 general election and any deadlines that apply before Election Day. Those may include dates connected to registration, registration updates, ballot requests, ballot return or other steps in the voting process.

Write down the dates that apply to your plan and leave time to complete each step. If a deadline or instruction is unclear, ask an election administrator what must be completed, where it must be submitted and when it must arrive.

Voters should also check whether an action must be completed by a particular date or received by election officials by that date. Confirming that distinction can help avoid a late application or ballot.

Check what will be on your ballot

The ballot lineup should be confirmed before voting. Request official ballot information connected to your voting address, then review every contest and ballot question listed.

A sample ballot can help a voter become familiar with the names, offices and questions before it is time to vote. Review the entire ballot, including items that may appear farther down the page. Make notes separately rather than marking or returning a sample ballot unless election officials instruct otherwise.

This guide does not list candidates because none are directly linked to the page. It also does not describe candidate positions. Voters should use official ballot information to identify who and what will appear before researching their choices.

Verify registration and choose how to vote

Check your voter registration status and confirm that your name and address are current. Anyone who needs to register or update a record should ask Montana election administrators which form or process to use, what information is required and which deadline applies.

Next, choose an available voting method and confirm its rules. Ask where voting takes place, what identification or documents may be required, when voting is available and how a completed ballot must be returned. Do not assume that instructions from another state or an earlier election apply in Montana in 2026.

Voters who need assistance or have accessibility questions should contact election administrators early enough to understand the available process before voting.

Make a final voting plan

Before casting a ballot, check the election date and relevant deadlines one more time. Confirm registration status, review the official ballot information and follow the instructions for the chosen voting method.

Keep election-office contact information with your plan in case a question arises. If instructions conflict with something seen elsewhere, use the directions issued by Montana election administrators and ask for clarification before submitting a form or ballot.

After completing a ballot, follow the official return instructions carefully. The key is to verify each required step in advance rather than waiting until the final deadline.

What to watch

  • Publication of the official election calendar
  • Release of ballot and sample-ballot information
  • Registration and ballot-request instructions
  • Voting-location and ballot-return guidance
